I fear that we in the tech media shoulder some responsibility for making people worry — sometimes to the point of obsession — about theirsmartphone’s battery life. It amazes me how close of an eye some smartphone owners keep on their devices.
We’re constantly monitoring our phone’s health.

To be fair, I’m like that too. A bit. No, not really. A lot.

And if there’s one thing that we battery watchers get good at spotting, it’s when the battery is discharging faster than normal. And there’s no easier thing to notice than a battery going from 100% to 99%.When the battery was new it may well have remained at 100% for a few hours. But after a few months of wear, that tick-over from 100% to 99% happens a lot quicker.

But why? Is this a problem?
No, it’s nothing more than normal battery wear.
Every charge/discharge cycle that your iPhone goes through wears the battery a little. 
According to Apple, the battery in your iPhone is designed to retain up to 80% of its original capacity at 500 complete charge cycles.

You can see this measure if you tap on Settings > Battery > Battery Health & Charging, and it’s under the heading Maximum Capacity.
Battery Health on IOS 16 showing Maximum CapacityThe more you use your phone, the more it wears the battery. That’s physics. And you can’t change the laws of physics.
The bottom line: As part of the normal battery-wear process, your battery will lose about 1 percentage point off this Maximum Capacity for every 25 cycles.
This, in turn, affects how quickly your iPhone’s battery drops. That is, an old iPhone charged to 100% holds less charge than a new iPhone changed to 100% because of this wear.

Also: The price of replacing your iPhone battery has gone up
But it gets more complicated.
If you watch that Maximum Capacity figure, you’ll notice — when your iPhone is new — that it takes weeks, maybe months, before that 100% maximum capacity rolls over to 99%.
Why is that?
Because the battery inside your iPhone has a higher actual capacity than Apple claims. Apple under-promises on the capacity because new batteries have a natural variation in capacity, and Apple would prefer that your battery has slightly more capacity — not less — than what’s in the spec sheet.

If you’re interested, you can actually get iOS to show you how much capacity your battery had when new, what its current capacity is, what its rated capacity is, and how many charge cycles it’s been through.
Confused? Don’t worry! Put simply, what this means is that when your battery is new, it can hold more power than its rated capacity; and because of this, it looks like it can stay at that 100% mark for longer. 
So, is this slow erosion of how long your battery will stay at 100% a problem?
No.
This is what normal battery wear looks like.

That said, there are a few steps you can take to take the stress off your battery to reduce additional wear.

Use a good-quality charger – either a genuine Apple charger or a good quality third-party charger.Keep your iPhone at room temperature as much as possible – don’t leave it baking in the sun or in a car window all day.Don’t keep your iPhone on a charger all the time – the battery is meant to be used.So, if this is normal, what are the signs of a dying battery?

Here’s what I look out for:
Rapid discharging over a few hoursCrashing when under load (for example, when playing a demanding game)Phone refusing to charge to 100%Physical damage such as bulging or overheatingThese are signs that your battery could be worn. But remember, all is not lost! It’s not much of a hassle to get it replaced, giving your iPhone a new lease of life.

The iPhone 15 reveal is happening on Sept. 12 during the Apple September Event. Apple hasn’t released much in the way of official details about its next best smartphone, but a glut of leaks, analyst predictions and insider speculations has given us an inkling of what to expect.
This much is clear: expect more changes than those brought by last year’s iPhone 14. Speedier and more power-efficient processors, higher resolution periscopic lenses, USB-C, and a handful of surface design alterations – and it’t be long until we have confirmation of changes coming.
With new features could also come a less welcome iPhone 15 price hike. Hopefully, that’s one rumor that will be proven wrong. Read on for all the details we have ahead of the next Apple event.

iPhone 15 Release DateApple plans to reveal the iPhone 15 on September 12, 2023, before the smartphone goes on sale a week later. The event will start at 10 am PT/ 1 pm ET, and will likely run for about an hour. At the event, we ‘ll likely see exactly what the iPhone 15 will look like and everything it will be able to do, including whether or not it’ll actually have that USB-C port we’ve been asking for.
When Can You Buy iPhone 15?You should be able to buy the iPhone 15 on September 22, according to Bloomberg’s own sources. (This corroborates an earlier report from 9to5mac). The last several iPhones have been released in September (barring the later October launch of the iPhone 12), with the iPhone 14 hitting shelves on September 16, 2022. The iPhone 15 is unlikely to be different.

iPhone 15 PriceThe iPhone’s price has remained static for the past few years, with the last three generations of the standard model launching for $799. But a report by Bloomberg claims it’s all changing for the premium-tier iPhone 15 Pro and Pro Max, as Apple plans to increase prices in anticipation of slowing projected phone sales.
The company is already dropping hints that a price rise is on the way. During a quarterly earnings call last February, Apple CEO Tim Cook said “the iPhone has become so integral into people’s lives” that customers are “willing to really stretch to get the iPhone devotees, in other words, can suck it up.
How much will the iPhone 15 Pro cost?For reference, here are the retail prices of the 128GB versions of the iPhone 14 models. The iPhone 15 probably won’t look too different:
iPhone 14: $799iPhone 14 Plus: $899iPhone 14 Pro: $999iPhone 14 Pro Max: $1,099iPhone 15 modelsLike the last few generations of Apple’s flagship smartphone, the iPhone 15 line-up is expected to consist of four models: the iPhone 15, iPhone 15 Plus, iPhone 15 Pro and iPhone 15 Pro Max.
A report from the top of this year suggests the Pro Max may be renamed Ultra, though Bloomberg later walked back on those claims and suggested Apple instead plans to introduce the Ultra as a distinct, higher-tier model in 2024.

iPhone 15 FeaturesAs ever, big changes are coming to the iPhone camera. Apple industry and markets analyst Ming-Chi Kuo predicts both the standard iPhone 15 and iPhone 15 Plus will inherit the 48-megapixel camera sensor of the iPhone 14 Pro and Pro Max. It’s a sizable upgrade on the 12-megapixel camera that’s been a feature of the last three generations.

The iPhone 15 Pro and Pro Max, however, are expected to get an even snazzier periscope lens. Already found on a handful of premium smartphones, periscope lenses essentially support high levels of optical zoom, letting you capture crisp pictures from a distance. With the Samsung Galaxy S23 Ultra sporting a 10x zoom periscope lens and the Google Pixel 7 Pro a 5x zoom, Apple may well be looking to catch up.

The Dynamic Island – the pill-shaped black cutout at the top of the iPhone 14 Pro and Pro Max – is expected to become a staple feature too. It’s essentially an interactive notification area that replaces the top notch, which has been a mainstay of the phone’s design since the iPhone X. It can display music controls, incoming phone calls, AirDrop transfers, and a bunch of other app alerts. And since it’s interactive, the notification cutout can be expanded, shrunk, or split in two if displaying multiple background activities. While it was previously only a feature of last year’s Pro iPhone models, several insider rumors suggest it’ll hop over to the standard iPhone 15 and iPhone 15 Plus.

For a while, it was also thought the iPhone 15 Pro and Pro Max would ditch their typical side buttons in favor of solid-state haptics that could vibrate and change intensity in response to pressure. But after Ming-Chi Kuo and others first hinted at the idea, they’ve more recently suggested that development issues have delayed integration, and Apple has reverted back to its standard physical button design.
iPhone 15 SpecsIt’s likely the whole iPhone 15 line-up will get a beefy chipset upgrade. Model identifiers pulled from the back end of a recent tvOS update suggest the standard iPhone 15 and Plus models will adopt the A16 chip found in the current iPhone 14 Pro and Pro Max.

The next-gen A17 chip, meanwhile, looks to be reserved for the coming Pro and Pro Max. It’ll be Apple’s first 3-nanometer chip and, according to one prolific leaker, will feature six CPU and GPU cores, each running at up to 3.7GHz. That will offer the usual performance improvements, but its manufacturer has also reportedly boasted it will reduce power consumption by up to 35%, according to a report from Bloomberg – a big boon for battery life. More unusually, a recent report by The Information claims that the same manufacturer has signed a deal to exclusively develop the 3-nanometer chips for Apple for a full year before making them for competitors. If true, it’ll be one way Apple keeps ahead of the game.

Analysts have also predicted the iPhone 15 will include a newer ultra-wideband communications chip to support compatibility with Apple’s recently unveiled mixed-reality headset, the Vision Pro. Apple has framed the headset as a consumer and commercial device that directly will integrate with several cores iOS apps. Improving the connectivity between the headset and other Apple devices seems like a natural step to shore up the Apple ecosystem.

iPhone 15 Design – What Will the iPhone 15 Look Like?At the top of the list of potential iPhone 15 design features is the disappearance of the Lightning port. After the EU introduced legislation last year requiring that all phones sold within its member countries use USB-C, Apple confirmed it would comply with the changes. It has until 2024 to do so, and is yet to clarify whether this year’s iPhone line-up will be the first to feature the port. It’s also yet to explicitly outline whether all iPhone models will make the switch to USB-C or just those sold within the EU.
Renders of the iPhone 5’s design provided to 9to5Mac by a Chinese case manufacturer show a USB-C port in place. They also show a handful of other design tweaks; the iPhone 15 Pro line will reportedly include:
Titanium frames, making it lighter and more durableThinner bezels thanks to new screen technology (that was first used on the Apple Watch Series 7 to make the wearable’s bezels thinner)More protruding camera lenses in a square array

More significantly, rumors suggest the mute switch – which has been present since the first iPhone– will be replaced by an Action button. It’s claimed to function as an all-purpose, programmable shortcut that can instantly open various apps and features. An iOS 17 beta build from July mentions several functions that can be assigned to it: silent mode, camera, flashlight, accessibility, focus, magnifier, translate and voice memos. We’ll have to wait to see exactly how it works in practice if it is even real in the first place.

Here’s everything you need to know about optimised battery charging on iOS including what it does, and how to turn it off.

Optimised battery charging is a feature on iOS 13 or newer that limits overnight charging to protect your phone’s battery in the long term. Charging your phone to 100% for extended periods reduces the battery’s lifespan, so Apple’s software only charges it to 80%, reducing strain on the battery. Using optimised battery charging can increase your phone’s lifespan, but it may not be beneficial if you have irregular sleep patterns or don’t charge your phone overnight. You can easily turn off the feature in your phone’s settings.

Have you ever noticed that when you charge your iPhone late at night it stops at around 80 per cent? This isn’t a bug, it’s a feature called optimised battery charging doing its thing. It’s designed to increase the longevity of your phone’s built-in battery, ensuring that it works optimally for years to come. However, it’s not always beneficial, so it’s useful to know how to turn it off, too.

In this article, we’ll tell you everything you need to know about optimised battery charging, including how it works, why you should or shouldn’t use it, and how to control it. Let’s dive in.

What does optimised battery charging do?

Optimised battery charging is enabled by default on all devices running iOS 13 or newer. It’s a feature that’s designed to protect your battery in the long term by limiting overnight charging.
The majority of people plug in their phones when they go to bed, leaving them plugged in overnight. This is convenient as it’s the one time that you know you’re not going to need your phone, and most homes have an outlet near the bed that can be used for charging.

As convenient as it is, it’s not the best thing for your battery. It’s not dangerous, there’s built-in protection on all modern smartphones that will stop the battery from overcharging, but keeping the battery at 100 per cent charge for extended periods reduces its lifespan.

That’s because as well as the physical age of your battery, its lifespan is also affected by its chemical age. The chemical age of your battery can be affected by how hot your battery gets, and how and when you charge your iPhone. As your battery chemically ages, the amount of charge it can hold will slowly decrease, meaning you’ll need to charge it more often.
iPhone 14 Pro Max shown from the bottom displaying Lightning portTo combat this, Apple’s software monitors your daily activity and will only charge the phone to 80 per cent when it’s plugged in at night. Then it will wait until just before your usual wake-up time to complete the charge to 100 per cent.
Only charging to 80 per cent reduces the strain on the battery, which can help to reduce the chemical aging of battery. When it’s working as it should, you won’t notice any difference from charging the old-fashioned way – except for the fact that your battery will remain in good health for much longer. You may also see a notification on your iPhone indicating that it’s using optimised battery charging, along with an estimate of when your iPhone will be fully charged.

Optimised battery charging does a few other clever things, too. Apple says that it only triggers in locations that you spend a lot of time in, such as at home or work, so long as you have location services enabled. This means that it shouldn’t impact you when travelling. Ironically, having location services turned on may actually run down your battery more quickly, as the GPS components in your iPhone will require power to make location services work. Indeed, turning location services off is one of the common suggestions for ways to extend your battery life.

Why should you use it?Using optimised battery charging means that your phone will have a much longer lifespan. There’s nothing worse than having a handset that works great but won’t hold a charge for more than a few hours, and this feature should help prevent that from happening.

Of course, batteries aren’t perfect, and they all have a finite lifespan. So even if you use this feature, you should expect your overall battery life to decrease as the years go by. It’s just that with this feature enabled, it’ll take much longer for that to happen, and the usable period is likely to greatly exceed the time that you use the device, before deciding to upgrade to a fancier model.
So, sound like a no-brainer, then? Well, there are a few scenarios where optimised battery charging might be more of a hindrance than a convenience.
Five reasons to buy the Apple iPhone 13 
The system requires iOS to learn your habits in order to work effectively, so if you keep irregular hours or regularly change shift patterns at work, then you might find that it’s not working as you’d hoped.

Similarly, if you don’t charge your phone overnight, then it won’t be doing anything useful – and could even slightly decrease your battery life by trying to learn your habits in the background.
In cases like that, it’s probably best to turn off the feature entirely. Thankfully, Apple makes this easy to do, and we’ll explain how in the next section.

Samsung’s best phone might be all Qualcomm, all the time.
According to a reliable leaker, all models of the Samsung Galaxy S24 Ultra will feature Qualcomm Snapdragon processors, regardless of the region.

 Samsung has a close relationship with Qualcomm in terms of Snapdragon chips. Buyers of the Galaxy S24 Ultra can expect a super-fast flagship phone no matter where they are located, but confirmation on the chips will only be provided at the official announcement next year.If you pick up the best Samsung phone next year you’re going to also get the best chips, according to a new report.

We’d been expecting Samsung to use the Qualcomm Snapdragon 8 Gen 3 in the United States but go with the Exynos 2400 in other parts of the world, including South Korea and Europe. Now, it appears that will only be the case for the Galaxy S24 and Galaxy S24 Plus – choose the Galaxy S24 Ultra and you’ll get Qualcomm silicon, no matter where you happen to be located.

That’s according to a new report by one X leaker who has a reliable track record when it comes to these kinds of things, although it’s always important to note that nothing is 100% guaranteed with leaks this far out. The Galaxy S24 lineup isn’t expected to be announced until January or February of 2024, for example.
All Qualcomm, all the timeThe leaker in question is @tech_reve, and they believe that “regardless of the region, all models of the S24 Ultra feature Qualcomm Snapdragon processors.” That will surely be music to the ears of some, although this Exynos chip might not be the poor performer that we’ve come to expect from Samsung’s in-house chip designs.

Regardless of the region, all models of the S24 Ultra feature Qualcomm Snapdragon processors. — Revegnus A recent Ice Universe leak, again on X, shared details of the Exynos 2400 clock speeds with the chip expected to have a 1o-core CPU. But given Samsung’s close relationship with Qualcomm and the fact it’s likely to use overclocked versions of the Snapdragon 8 gen 3, many will surely prefer to carry a phone with that chip inside.

Regardless, it’s looking increasingly likely that buyers of the Galaxy S24 Ultra will get a super-fast flagship phone no matter what part of the world they are in at the point of purchase. We’ll get confirmation of exactly what chips will go where when the new phones are announced next year of course, and givenSamsung’s leaky history we might even find out before then, too.

This is everything we have heard so far about the Apple iPhone 15 and iPhone 15 Plus.
The iPhone 15 and iPhone 15 Plus are expected to be announced on September 12, with pre-orders starting on September 15. The standard iPhone 15 models may have a frosted finish and new color options, while the display size is expected to remain similar to the iPhone 14. The iPhone 15 and iPhone 15 Plus could feature a 48-megapixel main camera sensor like the iPhone 14 Pro, but may not have the same camera upgrades as the Pro models.Apple iPhone leaks typically run throughout the entire year. No sooner does the latest iPhone series arrive – sometimes even before – then rumours start about the next models. For 2022, there were four iPhone models: the iPhone 14, iPhone 14 Plus, iPhone 14 Pro and the iPhone 14 Pro Max.
We’ve covered off what the rumours are saying about the iPhone 15 Pro and 15 Ultra in a separate feature, but here we are looking at what we can expect for the standard iPhone 15 and iPhone 15 Plus.

iPhone 15 release dateApple has sent out invitations to an event on 12 September, where we’re expecting to see the launch of the iPhone 15. The iPhone 14 series arrived on 7 September 2022, which was a week earlier than most expected, with Apple now falling back into its usual launch cadence.

That would likely mean the iPhone 15 is available to pre-order on 15 September, and available to buy from 22 September. It’s possible that not all models will go on sale at the same time, as has been the case in the past. iPhone 14 Plus was later than the iPhone 14 for 2022, so the same could happen this year too.
iPhone 15 designThe Apple iPhone 15 and iPhone 15 Plus are likely to look the same as each other, aside from their physical size. They will also probably be a little less premium in their material choice than the iPhone 15 Pro models – aluminum instead of stainless steel or titanium for example. So far, details have been thin on the ground in terms of their designs, though there have been a number of suggestions that the iPhone 15 models will be getting the Dynamic Island cutout we saw on the iPhone 14 Pro and iPhone 14 Pro Max in 2022. It’s also said that the Dynamic Island will include a proximity sensor within it rather than underneath it for the iPhone 15 models, though this shouldn’t change its appearance.
There wasn’t a huge design change between the iPhone 13 and the iPhone 14 so we wouldn’t be surprised to see a bigger difference in the iPhone 15 models, though Dynamic Island would sort of do this.
It’s also been claimed the iPhone 15 models could come in cyan and magenta color options and it’s been claimed the finish could be frosted rather than glossy, matching what we currently see on the iPhone 14 Pro models. Elsewhere, it’s also been suggested the iPhone 15 models could see a switch to eSIM only for the UK and Europe, matching what Apple did for the iPhone 14 models in the US.

iPhone 15 displayIt’s claimed the iPhone 15 and iPhone 15 Plus will feature the same display sizes as their predecessors – or at least very close to the same size. The iPhone 14 has a 6.1-inch Super Retina XDR OLED screen with 2532 x 1170 pixel resolution. This results in a pixel density of 460ppi. The iPhone 14 Plus meanwhile, has a 6.7-inch Super Retina XDR OLED screen with a 2778 x 1284 pixel resolution, resulting in a 458ppi.
Both devices have a 1200nits peak brightness and both support True Tone, Haptic Touch and HDR. It’s expected the iPhone 15 models will offer the same, though there is some talk of a 6.12-inch or 6.2-inch display for the standard iPhone 15. There was also talk of slimmer bezels around the display, though this appears to be for the Pro models rather than the standard models.
Whether the iPhone 15 models will adopt the Always On Display featured on the iPhone 14 Pro and iPhone 14 Pro Max isn’t clear yet, though it would require them to also adopt ProMotion, and rumours are suggesting that won’t be the case.

iPhone 15 hardware and specsThe Apple iPhone 14 and iPhone 14 Pro opted for the same chip as the iPhone 13 Pro and iPhone 13 Pro Max models rather than running the A16 chip featured on the iPhone 14 Pro and iPhone 14 Pro Max. It’s possible Apple will do the same for the iPhone 15 and iPhone 15 Plus, moving them onto the A16 chip rather than the A17, which is what is expected to run the iPhone 15 Pro and 15 Ultra.
It’s also claimed that Apple will use Qualcomm’s 5G modem for the iPhone 15 models rather than a modem built in-house as it was initially thought for this year. Rumors suggest the first model to run an in-house 5G modem will be the iPhone SE (2024).
In terms of storage, no rumours have appeared detailing any changes to storage as yet. If the iPhone 15 and iPhone 15 Plus offer the same as the iPhone 14 and iPhone 14 Plus, then we can expect 128GB, 256GB and 512GB options. There have been suggestions of improved RAM though.

While there might not be huge changes, we’d also expect some battery improvements on the iPhone 15 and iPhone 15 Plus. The iPhone 14 Plus has an excellent battery performance, so we’d expect similar from the iPhone 15 Plus. It’s also been claimed this will be the year Apple will finally make the switch from Lighting to USB-C, though it’s said you will need a certified cable and charging speeds may be restricted depending on the cable. That said, we might see a bump to 35W charging – and there’s also talk of braided cables for some models, or color-matched cables for others.

iPhone 15 camerasWhen it comes to cameras, there have been reports suggesting the iPhone 15 and iPhone 15 Plus could see an upgrade to the 48-megapixel main sensor, though it may not be the same as the one found in the iPhone 14 Pro and iPhone 14 Pro Max. It’s also claimed that the standard iPhone 15 models might feature a stacked image sensor that will allow more light to get in, though it’s said a couple of different configurations have been tested. It’s also not clear if the iPhone 15 Pro models will get This upgrade.

If the standard iPhone 15　models do move to a stacked image sensor with a 48-megapixel resolution, we don’t expect to see the iPhone 15 or iPhone 15 Plus offer the telephoto lens offered by the Pro models in order to continue to offer a differentiation between the standard and Pro models.
We would expect to see similar features across the four models though, with perhaps a couple of extras on the iPhone 15 Pro and iPhone 15 Pro Max.

Apple slows down processors used in legacy iPhones – but what does that mean?
In 2017, Apple revealed it slows down older iPhones such as the iPhone 6, iPhone 6S, iPhone 7, and the first generation iPhone SE in order to prevent unexpected shut downs by managing the performance peaks.

The performance management feature – or throttling as some have described it in the past – is also included on the iPhone 8, 8 Plus, iPhone X, iPhone XS, iPhone XS Max and iPhone XR, but it only kicks in after an unexpected shutdown first occurs on a device with a battery that has diminished ability to deliver maximum instantaneous power.

Apple iPhonesfrom the iPhone 6 and later also have a Battery Health tool that was introduced with iOS 11.3 back in March 2018, along with the ability to turn off the iPhone’s batterymanagement feature. Here is everything you need to know about Apple iPhone’s Battery Health and performance management features and how to control them.
What is the iPhone performance management feature?Apple’s performance management feature is specific to iPhones and it’s designed to prevent a device from unexpectedly shutting down so the device can still be used. Unexpected shutdowns can occur for a number of reasons, be that extreme cold temperatures, or a device with a battery of high chemical age, for example.

Apple’s iOS software will dynamically manage performance peaks in order to manage shutdowns. It looks at a combination of things, like device temperature, battery state of charge and battery impedance. The software then assesses whether action is required and if it is, the maximum performance of some of the system components, like the GPU and CPU, will be managed in order to balance out workloads and allow for a smoother performance overall.

Some of the things you might notice when the performance feature has kicked in are: Longer app launch times, lower frame rates when scrolling, backlight dimming, lower speaker volume, gradual frame-rate reduction in some apps, disabled camera flash in extreme cases and apps refreshing in the background may require reloading upon launch.
Some of the things that won’t be impacted by the performance feature are: Mobile call quality and networking performance, captured photo and video quality, GPS performance, location accuracy, sensors like gyroscope, accelerometer, barometer and Apple Pay. 

With regards to the performance management feature, Apple describes it as: “If the battery health is able to support the observed peak power requirements, the amount of performance management will be lowered. If an unexpected shutdown occurs again, then performance management will increase. This assessment is ongoing, allowing more adaptive performance management.”
iPhone Battery Health explained: Why Apple throttles iPhone performance and how you can control it photo 2Apple
What is the Battery Health feature? Apple iPhones running iOS 11.3 and later have a Battery Health tool built in. To access the tool, go to Settings > Battery > Battery Health. From there, you’ll see information about your iPhone’s maximum capacity and peak performance capability. 
You’ll also see if your iPhone is being slowed by Apple’s performance management feature.
For example, we have an older iPhone XR showing as having a 94 percent battery capacity. Apple is not yet throttling the phone though: “Your battery is currently supporting normal peak performance”.
In the Battery Health feature, you’ll also see whether your iPhone needs service and you can subsequently turn off the controversial performance management feature that’s throttling your iPhone if you want to.

How to disable throttling on an iPhoneThe ability to disable – and even enable – throttling is only available for iPhones more than a year old running iOS 11.3 and later.
Under Battery in the Settings app you’ll notice the Battery Health option. Tap it. You’ll then see a screen with a link to more information about lithium ion batteries. Below that, you’ll see your battery’s maximum capacity.

If this indicator is under 80 per cent, you’ll see another message at the bottom of the screen that warns your iPhone’s battery is “significantly degraded”. There will be another link that will point you to a page about how to get your phone serviced. 
Disable ‘performance management’ featureIf your device has shutdown due to battery degradation, this same screen will tell you that “performance management has been applied to prevent this from happening again”.
There will also be an option to disable the throttling. You can’t enable the performance management feature until you experience another shutdown. Your iPhone will auto-enable it should that ever happen.

It’s also worth noting that “all iPhone models include fundamental performance management to ensure that the battery and overall system operates as designed and internal components are protected. This includes behavior in hot or cold temperatures, as well as internal voltage management. This type of performance management is required for safety and expected function, and cannot be turned off”. 

What do those percentages mean?In the Battery Health menu, you’ll see a percentage that indicates your iPhone battery’s maximum capacity, followed by a message explaining your iPhone battery’s peak performance capability. The message you get depends on the percentage shown.
For instance:
100 percent: Your battery is currently supporting normal peak performance.95 percent: This iPhone has experienced an unexpected shutdown because the battery was unable to deliver the necessary peak power. Performance management has been applied to help prevent this from happening again. Disable…

79 percent or less: Your battery’s health is significantly degraded. An Apple Authorized Service Provider can replace the battery to restore full performance and capacity. More about service options…Unknown: This iPhone is unable to determine battery health. An Apple Authorized Service Provider can service the battery. More about service options…
Maximum capacity and peak performance

Maximum battery capacity measures your iPhone’s battery capacity to when it was new. Batteries will start at 100 per cent when first activated and will have a lower capacity as the battery ages. According to Apple, a normal battery is designed to retain up to 80 per cent of its original capacity at 500 complete charge cycles when operating under normal conditions.

Now, as far as peak performance capability goes, it is the ability of your iPhone’s batteryto supply adequate charge. If your iPhone’s battery maximum capacity is under 80 per cent, then its health has been significantly degraded and it needs replacing.

Are you tired of constantly having to charge your iPhone throughout the day? If your iPhone’s battery health goes down, it cannot keep up with your busy schedule. Battery health reducing fast is one of the most common complaints among iPhone users. But don’t worry. I will share ways to maintain your iPhone’s battery health. 

First, you should know why your iPhone’s battery health is reducing so fast. Here are some of the most common reasons:

High usage: Constantly using your phone for streaming, gaming, browsing, and downloading large files can put a strain on the battery and cause it to reduce fast. Leaving apps running in the background: When apps run in the background, they continue to use power, especially those that track your locations, even when you’re not actively using them. Battery life can be significantly reduced as a result.

Exposure to heat: High temperatures can damage the battery and cause it to reduce more quickly.Not updating the iOS: The update patches contain iOS optimizations. So, not updating your iPhone can also affect the battery’s health.Using third-party battery cases or chargers: If you use non-Apple accessories, it can cause damage to the battery and degrade its overall health over time.Battery age: Batteries have a limited lifespan. And as they age, they will naturally lose some of their capacity.

11 Ways to maintain your iPhone’s battery healthTo view the current health status of your battery, go to Settings → Battery → Battery Health & Charging and check the Maximum Capacity percentage.
Go to Settings, Battery, Battery Health & Charging, Check Maximum CapacityApple considers 80% and above battery capacity to be ideal. To avoid going below that mark and stopping your battery from malfunctioning, you must employ best practices and maintain your iPhone’s battery health.
1. Don’t let your iPhone overheatYour iPhone battery’s worst enemy is extreme temperatures and heat. According to Apple, your iPhone can operate without harm at temperatures as high as 95°F. Beyond that, the battery may suffer irreparable harm, and even your iPhone may explode. Though your iPhone has built-in safety features to temporarily turn it off in certain circumstances. 

To prevent your iPhone’s battery from overheating, don’t leave it in the sun or in front of a heater vent in your car. Moreover, temperatures below 32°F (0°C) also degrade battery life. It impairs the battery’s capacity to store charges. So, taking precautions will assist in keeping your iPhone’s battery in good shape.

2.Use Apple’s original chargersApple always advises using its official cords, adapters, and wireless chargers. The third-party chargers have poor wires and don’t maintain standards properly though they may juice your iPhone. Moreover, the official apple accessories prevent power surges and short circuits.
Use Apple original chargersSome petty companies make copy products. So, if you bought MagSafe products online, it’s good to check the Apple MagSafe charger firmware and ensure you’ve got a genuine product.

3.Avoid letting your iPhone dieLetting your iPhone battery discharge is one of the worst things you can do to it. If a discharged lithium-ion battery is left in that condition for a long time, it will go into a deep discharge state and never function again. So, Apple addressed the issue and made iPhone batteries retain some reserve energy after being dead. 
However, if your iPhone runs out of power, charge it as quickly as you can. Also, use your iPhone’s Low Power mode when the battery is 20% or less. It prolongs the battery life until you can go to an outlet. Usually, I juice my iPhone multiple times a day to avoid completely draining it.

4. Don’t charge overnightMost people charge devices overnight. But do you know overcharging your iPhone harm the battery and reduce the battery’s health? Maybe your iPhone needs one hour of charging but plugging it in for 7-8 hours results in overcharging. It pushes more current into already charged cells. 
Therefore, to avoid overcharging turn on adaptive charging. It’s a built-in feature in your iPhone to maintain the battery healthy. Go to Settings → Battery → Battery Health → toggle on Optimized Battery Charging. So, it will enable your iPhone to learn your charging pattern.

Besides, juicing iPhone fullest generates heat. You may notice the charging speed becomes slow after 80%. Therefore, I suggest avoiding charging your iPhone to 100% and keeping the battery level between 40% and 80%.
6. Get the best wireless charging iPhone casesIf you are using wireless channelargers, always use an official MagSafe case for that. So, your iPhone will not struggle to maintain a good magnetic connection and capture the charge properly. Besides, premium cases tend to have plugs to close the charging port. Therefore, dirt and dust won ‘t be gathered. 

Ringke Magsafe case for iPhone 14Also, waterproof cases safeguard your iPhone from water damage and protect the battery. But keep your eye out to check if your iPhone is overheating due to the case. If required, take off your iPhone cover while it’s charging to avoid this problem.
7. Measures to store iPhone for the long termAs I said before, keeping your iPhone switched off for a long could result in battery malfunction. So, if you are storing your iPhone, charge it to 50% and turn it off. Also, don’t forget to juice it once every six months. Don’t charge to 100% while storing your phone for a lengthy period of time.
8. Optimize your iPhone’s settingsWithout a doubt taking the mentioned precautions will help to maintain your iPhone battery health. Besides, I have optimized a few settings to improve my iPhone battery capacity and fix the battery drain issue. I’d suggest you do the same. 

9. Turn off the Always-On displayFor the iPhone 14 Pro lineup, Apple added a new feature called Always-On display. It keeps the lock screen turned on in low-power mode. So, the display is updated once per second with dimmed screen brightness. As the function is always in operation, turning off the Always-On display will get you the most use out of your iPhone’s battery.

The iPhone 14 Pro Max is the best iPhone available right now, but it probably won’t be for long, as the iPhone 15 line is set to launch on September 12. It’s almost guaranteed that the iPhone 15 Pro Max will be a better phone , but what about the standard iPhone 15? Will that in any way better Apple’s current top handset?

That’s what we’ll aim to answer below, by looking at the key differences between these two phones. Obviously, until Apple unveils the iPhone 15 we won’t know anything for sure about that phone, but leaks and rumors have given us a good idea of ​​what to expect.

So from the price to the design, display, cameras, performance, and battery, here’s how the iPhone 15 is likely to compare to the iPhone 14 Pro Max.
IPHONE 14 PRO MAX VS IPHONE 15: SPECS COMPARISONBefore discussing the differences between these phones in detail, it’s helpful to get an overview of their core specs, so we’ve included that in the table below. In the case of the iPhone 14 Pro Max, these are confirmed specs, while for the iPhone 15 they’re based on leaks, rumors, and educated guesses.
IPHONE 14 PRO MAX VS IPHONE 15: PRICE AND AVAILABILITYApple iPhone 14 Pro Max angle with screen on
The iPhone 14 Pro Max will probably cost more (Image credit: Future / Lance Ulanoff)The iPhone 14 Pro Max is globally available and starts at $1,099 / £1,199 / AU$1,899, for which you get 128GB of storage.

The iPhone 15 release date is set for September 12, and while we don’t know for sure what this phone will cost, it’s sure to be at least as pricey as the iPhone 14, which starts at $799 / £849 / AU$1,339. That’s again for 128GB of storage.
If anything, the iPhone 15 price will possibly be a bit higher, as some sources suggest as much, with one saying the iPhone 15 costs 12% more to produce than its predecessor.
But not all sources agree that the price will be increasing, and even if it does, it will probably still be a fair bit more affordable than the iPhone 14 Pro Max – though note that the latter phone will likely see a price drop when the new models land.
IPHONE 14 PRO MAX VS IPHONE 15: DESIGN AND DISPLAYUnofficial renders showing the front and back of the iPhone 15 Plus

An unofficial render showing how the iPhone 15 might look (Image credit: 9to5Mac)The iPhone 14 Pro Max has a matte glass back, a stainless steel frame, and a large screen, leading to dimensions of 160.7 x 77.6 x 7.9mm and a weight of 240g.
The iPhone 15 might also have a matte glass back, but will probably have an aluminum frame, and be much smaller. We don’t know the exact dimensions but they’re likely to be similar to the iPhone 14, which is 146.7 x 71.5 x 7.8mm. The weight will probably also be similar to that phone’s 172g, making it much lighter than the iPhone 14 Pro Max.
It will probably match the iPhone 14 Pro Max’s IP68 rating for dust and water resistance though, as well as looking generally similar, with a Dynamic Island on the front and a square camera block on the back.

However, the iPhone 15 might have curved edges if leaks are accurate, which the iPhone 14 Pro Max doesn’t, and the colors will almost certainly differ. Specifically, the iPhone 14 Pro Max is available in Deep Purple, silver, gold, and Space Black, while the iPhone 15 colors are rumored to include Cyan, Light Blue, Pink, Midnight, Starlight, and Product (RED), or a subset of those.
As for the iPhone 15 screen, that will probably be similar to the iPhone 14’s, meaning a 6.1-inch 1170 x 2532 OLED display with a 60Hz refresh rate and a peak brightness of at least 1,200 nits. will probably just be the presence of a Dynamic Island.
The iPhone 14 Pro Max also has a Dynamic Island, but attached to a much larger, 6.7-inch 1290 x 2796 OLED display with a 120Hz refresh rate, and a likely higher peak brightness of 2,000 nits. than we’re expecting the base iPhone 15 to have.

IPHONE 14 PRO MAX VS IPHONE 15: CAMERAApple iPhone 14 Pro Max camera array
The iPhone 14 Pro Max has more cameras than we expect from the iPhone 15 (Image credit: Future / Lance Ulanoff)The iPhone 14 Pro Max has a triple-lens camera on the back, consisting of a 48MP main sensor, a 12MP ultra-wide, and a 12MP telephoto, offering 3x optical zoom. There’s also a 12MP camera on the front for selfies.
The iPhone 15 camera is unlikely to match this, with rumors widely suggesting it will have just a dual-lens rear camera, with no telephoto snapper. However, the ultra-wide and selfie camera will likely have 12MP sensors, like those on the iPhone 14 Pro Max.
That just leaves the iPhone 15’s main camera, which will reportedly be 48MP, like the iPhone 14 Pro Max, but possibly with a smaller (and therefore weaker) sensor.
IPHONE 14 PRO MAX VS IPHONE 15: PERFORMANCEA picture of the A16 Bionic chipsetOne area where these two phones could be very similar is their performance, as the iPhone 15 might inherit the iPhone 14 Pro Max’s A16 Bionic chipset, and will probably also have the same amount of RAM (6GB).
So you likely won’t get a power upgrade by replacing your older iPhone 14 Pro Max with a newer iPhone 15, but nor will the 14 Pro Max beat any model in the iPhone 15 line for performance, assuming leaks are accurate.
IPHONE 14 PRO MAX VS IPHONE 15: BATTERYApple iPhone 14 Pro Max bottom edge
The iPhone 14 Pro Max has a Lightning port (Image credit: Future / Lance Ulanoff)iPhone 15 battery leaks suggest the phone will have a higher capacity one than its predecessor, at 3,877mAh, up from 3,279mAh battery in the iPhone 14. However, even if that’s true it will still have a smaller battery than the 4,323mAh iPhone 14 Pro Max.
Of course, the iPhone 15 will also have a smaller screen to power, and if it has the same chipset as the iPhone 14 Pro Max (as we’re expecting) then it will likely be similarly power efficient, so it’s unclear which phone will last longer between charges. The iPhone 14 Pro Max should have its variable refresh rate on its side though in terms of minimizing battery drain, as it can move between 1Hz and 120Hz as needed, whereas the iPhone 15 will probably be locked to 60Hz.

It’s also unclear which phone will charge faster. The iPhone 14 Pro Max officially supports up to 20W charging, though third-party tests have found it can charge at around 27W. However, the iPhone 15 may get 35W charging according to one report. haven’t heard this from other sources though, so we’d take it with a pinch of salt. Alternatively it will probably top out at 20W like the iPhone 14.
One big difference though will be how you charge these phones, as while the iPhone 14 Pro Max charges via a Lightning port, the iPhone 15 will probably switch to USB-C.
IPHONE 14 PRO MAX VS IPHONE 15: VERDICTThe iPhone 14 Pro Max might be a year older than the yet-to-be-launched iPhone 15 but it will almost certainly be the better phone in most ways.
Going by what we’re expecting from the iPhone 15, it’s likely that the iPhone 14 Pro Max will have a larger screen, a higher refresh rate, better (and more) cameras, and a bigger battery.

However, there’s a chance the iPhone 15 will charge faster, and it will also probably use USB-C rather than Lightning, which many people will likely consider an upgrade. A lot of other aspects will be similar between the two phones too, such as their chipsets and the presence of a Dynamic Island. All that, and the iPhone 15 will almost certainly cost less than the iPhone 14 Pro Max.
So depending on what you want from your phone, an argument could definitely be made for buying the iPhone 15, rather than the iPhone 14 Pro Max. But if you already have an iPhone 14 Pro Max, there’s no real reason to buy the standard iPhone 15 – you should look to the iPhone 15 Pro Max instead.
