As phones have become more capable of performing various tasks, allocating battery power has become crucial to maximizing its lifespan, especially if your smartphone is draining fast. Today, our phone’s SoC significantly regulates power consumption between the apps and features we use daily. Even if you don’t have one of the Android phones with the best battery life, you can still extend your device’s lifespan with this feature. Let’s look at how Android’s Adaptive Battery works and how you can ensure it’s turned on.

What is Android Adaptive Battery, and how does it work?

samsung galaxy s22 batterydisplayWhen you are using your phone, it isn’t just the app you have open that is eating up your battery life. Even when you put your phone down and aren’t touching it, many background processes run behind the scenes. For example, many apps actively retrieve information from other apps, such as contacts or location data, not to mention all the external cellular and Wi-Fi connections.

All of these processes and more need varying amounts of energy to function. Without anything to coordinate power consumption, you would notice a big difference between an optimized battery and a device without one. An Adaptive battery is how your Android phone makes it through an entire day of usage or more. Here are a few essential system tools that Adaptive Battery uses.

Limiting background appsThe most common way Adaptive Battery saves minutes to hours of battery life is by restricting how apps run in the background. As mentioned earlier, some apps can consume a lot of power without you knowing it. When Adaptive Battery is turned on and an app is running too heavily, you will get a notification with the option to put it to sleep.

Over time, Adaptive Battery will learn which apps take up the most background usage and limit some of their functions. This doesn’t really affect your phone performance, but it means the battery won’t drain drastically when your phone is idle.
Learning your habitsAnother way Adaptive Batterylives up to its name is by learning the patterns of how you use your phone. After having Adaptive Battery enabled for some time, your phone will keep track of what apps you use the most, how long you use them, and how quickly your battery drains when not optimized.

Eventually, your Android phone will utilize this data to fine-tune how it expends a full battery so that it can last throughout your daily usage. A crucial piece of information in this equation is learning your charging habits. Once the time is regular enough, Android will start stretching your battery life to when it anticipates you will plug in your phone to charge.
Reducing performanceOne of the subtler ways Adaptive Battery improves battery lifeis by slightly reducing performance. Chips take a lot of power, and your battery can last much longer if that power is reduced to match your current needs.
On Samsung Galaxy phones, a complimentary feature to Adaptive Battery in the settings lets you change your device’s processing speed. This tool can save you more battery life than Android’s Adaptive Battery does. The Exynos processor in the flagship S-series devices barely lags in the “optimized” state, either. However, the difference in performance can be more noticeable in other Android devices, but if you are out and about without a charger, that might not be a concern.

How to turn on Android Adaptive BatteryHere’s how to turn on Adaptive Battery on a Google Pixel or Samsung Galaxy phone.

Most of us — casual users and enthusiasts alike — are forever searching for smartphones with the longest battery life. And while fast charging keeps us topped up every day, the absence of replaceable batteries means eventually, the lithium-ion cells enclosed in our phones are going to age and deteriorate, making it harder to maximize battery life.
If you’ve held onto a phone for a couple of years, you’ve probably noticed the battery doesn’t seem to last as long as it did when your handset was brand new. Four or five years down the line, many phones struggle to make it through the day on a single charge. Holding onto a phone even longer can even spell trouble for reliability too as you may face sudden shutdowns.

Unfortunately, battery capacity inevitably declines with age. But that doesn’t mean you can’t do anything to prolong the lifespan of your smartphone’s battery. If you’ve ever wondered what the best way to charge your battery is, here are some scientifically proven tips to maximize battery life.
If you’re in a hurry, here’s a quick summary of the best battery life-maximizing tips you should keep in mind:

Avoid full charge cycles (0-100%) and overnight charging. Instead, top up your phone more regularly with partial charges.Limiting your smartphone’s maximum charge to 80-90% is better for the battery’s health than topping up to completely full everytime.Use fast charging technologies sparingly and when your device is cool.Heat has the potential to accelerate battery health degradation. Don’t cover your phone when charging, and keep it out of warmer places.Don’t play intensive games, stream videos, or run other intensive workloads while charging to avoid heat and stressing the battery.Keep reading for a more detailed explanation of what factors will prolong your battery life
Partial charging is a healthy habitGoogle Pixel Stand wireless charging Galaxy S21 UltraOne particularly persistent battery myth is that you need to occasionally fully discharge and recharge to erase “battery memory.” This couldn’t be more wrong for lithium-ion batteries. It’s a leftover myth from lead-acid cells, and it’s pretty undesirable to Charge your modern smartphone in this way.
Partial charging is just fine for lithium-ion batteries and can have some positive benefits for cell longevity. To understand why it’s important to appreciate how a battery charges. Li-ion batteries draw constant current and operate at a lower voltage when closer to empty. This voltage gradually increases as the cell charges up, leveling off at around a 70% charge before the current begins to fall until the capacity is full.

Partial charging is just fine for lithium-ion batteries and even has some positive benefits.Notably, operating at a low voltage is good for a battery’s lifespan, increasing the number of available charging cycles before you’ll start to see a significant reduction in capacity. Roughly speaking, every 0.1V decrease in cell voltage doubles the cycle life, according to Battery University. Therefore, charging up your phone in that 30% to 80% range keeps the voltage lower and might slightly prolong the battery’s lifespan.

Avoid idle chargingGoogle Pixel 7a charging plug and wireless dockCharging overnight or in a cradle during the day is a very common habit, but it’s not recommended for several reasons (the old “overcharging” myth isn’t one of them). First, continuous trickle charging of a full battery can cause plating of the metallic lithium, which reduces stability in the long term and can, in rare cases, lead to system-wide malfunctions and reboots. Second, as we just mentioned above, it leaves the battery at a higher stress voltage when at 100%. Third , and most important, it creates excess heat caused by wasted power dissipation.
Some phones disable or slow down charging when nearing full capacity. Use these options.Ideally, a device should stop charging when it reaches 100% battery capacity, only turning the charging circuit back on to top up the battery now and again — or at the very least reducing the charging current to very small amounts.

While some phones disable charging once full, many continue to pull up to half an amp and sometimes more from the wall outlet. Turning smartphones off doesn’t make a difference in many cases either. While this isIt’s not a massive amount of power, it’s going to stop your phone from cooling down as quickly and will continue to cycle through a small part of the battery, resulting in a mini-cycle.A final point worth mentioning is parasitic load. This occurs when the battery is being drained significantly at the same time as being charged, such as watching a video or gaming while charging.

Gaming or watching videos while charging is bad because it distorts charging cycles.The best way to avoid parasitic loads is to turn your device off while charging. But that’s not really realistic. Instead, it’s best to keep the workload light while the device is plugged in, leaving it idle most of the time. Browsing the web is Probably fine. Also, remember to unplug it once the battery is topped up enough.
Heat is the enemy of long battery lifeASUS ROG Phone 5 product shot of the battery and charging logos up closeAlong with all of the above, temperature is an equally key contributor to longevity and maximizing battery life. In fact, it’s arguably the biggest killer of long-term battery health. Like high voltages, high temperatures stress the battery and make it lose capacity far more quickly than when kept at lower temperatures.

Leaving your phone to fast charge up for 5 to 15 minutes won’t lead to major overheating problems, but I certainly don’t recommend using them for a full charge. Instead, you’d be better off using a temperature-aware fast charging solution or switching to a slower charger, especially if you plan to plug your phone in overnight.

How to maximize smartphone battery health long-termmotorola edge plus charging indicatorLithium-ion battery technology is well understood these days, and smartphones are built around our use cases, but bad habits and myths still permeate the public consciousness. While most of these habits won’t severely negatively impact your phone’s battery life in the medium term , the decline in removable phone batteries means we should take extra precautions to maximize battery life and thus our smartphone’s longevity.

Broadly speaking, smaller regular charge cycles and keeping your phone cool are the key things to remember. Although I should point out that different phone batteries will always age slightly differently depending on how we treat them.

Users are forever in search of the best smartphone that has longer battery life.Gone are the days where batteries are easily replaceable. Today, we have to be conscious of our battery usage to minimize the expensive professional service that comes with smartphones.

Almost all smartphones are equipped with lithium-ion (Li-ion) batteries and while we all use the same type, no battery has the same lifespan. It all depends on our habits and how we use our phones that can determine how long can we keep the health of our smartphone batteries.

Best Practices to keep your Smartphone Battery HealthyIf you have been with your smartphone for more than a year, you might notice that batteries don’t last long compared to when it was brand new. Down the line, many phones can’t make it through a day with a single charge.

There are various ways to extend your phone battery lifespan. You might be familiar with it or it might sound new to you, but here are some best practices you can follow to keep your smartphone battery healthy:
Partial ChargingMost of us are guilty of fully charging our phones out of habit but in reality, it’s bad for the battery. Also, some are using their phones until the battery goes 0 percent before plugging it in, which should be avoided.
The best way to charge your phone and extend its lifespan is to charge it partially and frequently. For example, you can charge it for up to 80% and use it until it goes to 20% before charging it again. With this charging cycle, you can improve yoursmartphone’s battery life.

Avoid Extreme HeatLi-ion batteries don’t respond well to heat or extreme cold. If you are located in a cold area, its’ best to use thick phone cases that can keep it warm. For hot weather, don’t leave your phone exposed to sunlight. Heat is the worst enemy for Li-on batteries while cold might damage its health temporarily.
It’s best practice not to leave or store your mobile device in an enclosed space where there’s minimum ventilation as it raises the phone’s temperature, especially inside a hot car.

Decrease Screen BrightnessTurning down your screen brightness will save energy. Your smartphone screen is the component that uses battery the most. For iOS and Android devices, it gives you an option to automatically reduce the screen brightness when there’s light, though it still uses a light sensor. It’s advisable to disable auto-brightness.
You probably don’t require the full brightness, so manually setting your screen’s brightness depending on the ambient lighting is best recommended and will save your phone battery life.

Avoid Using Phone While ChargingMost people can’t keep away from their phones because it’s now considered a necessity. However, when it’s charging, it is better to avoid using it. When you use apps that require a large proportion of battery to operate, it’s consuming a lot of energy, thus reducing your battery life in the process.
It can also lead to overheating the device and as mentioned earlier, heat is the worst enemy for Li-on batteries. The best solution is to turn it off while charging, or if it’s really necessary to use it, then keep the workload very light when your phone is plugged in.
Avoid Using Non-Compatible Charging CablesThe most common practice people do is to use a counterfeit or third-party charging cable. You might think that you are saving some money because you bought it for a lower price, but it can seriously harm your smartphone battery.
Accessories that are not manufactured by the original provider are made of cheap materials that don’t work the same way as the original cables. Ensure that you are only using the right charging cables to protect not only your battery but also your smartphones.
Reduce Screen Timeout or Auto-LockSimilar to laptops or computers, your mobile’s screen can automatically turn off if not in use. You can save energy by reducing the screen timeout or auto-lock by 1 minute or even 30 seconds. Both iPhones and Androids have these features and it’s easy to set up.

Check Your AppsAll smartphone apps use power and data even if they are not in use, like Facebook. To extend your battery life, disable the background refresh activities of apps that aren’t crucial and do it regularly. When apps update, some new features are added and might consume more energy, so you’ll notice your battery draining. Make it a bit to monitor apps that consumes power even if you don’t use them.

Nowadays, Lithium-ion battery technology is more understood, but some myths remain in our consciousness. While most of the habit doesn’t severely impact your smartphone’s battery life, the decrease in removable batteries should be a reminder that we need to take precautions to prolong our smartphone’s battery life.

While iPhones are built with extreme precision and care, they are not immune to common issues. One of those issues is the iPhone not charging one. If you are facing this issue and thinking why my iPhone won’t charge, then there is no need to panic. There are several hacks you can try at your end to either get to the root of the issue or even solve it by yourself.
Even for a seemingly straightforward task like charging, there are several components involved that need to work properly. In this guide, we’ll take a look at everything that can cause the iPhone charging problem and eliminate possible reasons one at a time.

What Could be the Reasons Behind the iPhone not Charging Issue?Wondering why my iPhone is not charging? Well, there could be multiple culprits behind this annoying issue. For instance, the problem could be due to an uncertified charger or a rugged case that might not be supporting Qi-wireless charging or even a scrap of lint that may have sneaked into the charging port. There can be issues with the charging adapter, a faulty software might be preventing the phone from charging or there can be an underlying hardware issue. Thus, we are going to try out all the possible solutions that can help you resolve the iPhone not charging issue.

Remove the Gunk out of Your iPhone’s Charging PortWell, the first thing you should do is check if the lightning port of your iPhone is blocked by gunk or small particles of lint. Believe it or not, debris tends to get stuck in the port and builds up over time to prevent iPhone from charging when plugged in. So, you should clean the port frequently to ensure it can remain clean.
To clean the port of your iPhone, you need to first shut it down. Then, use a normal toothpick to remove the lint gently. Be more careful while cleaning the port as the pins may get damaged and you will have to replace the charging port.

Check Your Lightning Cable and Power AdapterWhile the market is flooded with chargers, not all of them are secure and certified to power iPhones. If you are using a charger which is not Mfi (Made for iPhone/iPad/iPod) certified, you will frequently get a warning pop-up saying, “accessory may not be certified.” As part of security measures, iOS won’t let you charge the iOS device using the uncertified charger.

If your charger is MFi certified, ensure that both the lightning cable and power adapter aren’t damaged. Try using another cable/power adapter to charge your iPhone. If you can charge using another charger, that means your charger is at fault. While the original Apple charger can be too costly, there are several high-quality cables available online that are less expensive. You just need to make sure they are MFi certified and have the recommended 2.1 amps power capacity.

Ensure that the Case Supports Wireless ChargingIf you use a wireless charger to power up your iPhone 8 or above, ensure that the case is compatible with wireless charging. Yeah, you got that right! Not all iPhone cases support Qi-wireless charging, especially the covers that are rugged or the ones that feature metal back plates.
So, just in case you have installed a heavy-duty case or a ring holder cover, remove it before putting the iPhone on the wireless charger.

If you use Qi-enabled wireless chargers, we would recommend you use slim cases that support wireless charging. This way, you won’t have to take the pain of removing the case before putting the iPhone on the charger.
If iPhone Stopped Charging at 80 PercentIf your iPhone won’t charge beyond 80 percent, then you might have nothing to worry about. To extend the lifespan of their device batteries, Apple has started using the Optimized Battery Charging feature. It is available in every Apple device, iOS 13 and higher models.
The feature uses machine learning and temperature sensors to detect when you use your phone the most and if the phone is getting too hot while charging. It will stop charging the phone when it hits the 80 percent mark. If your phone isn’t charging beyond this point, wait for a couple of hours and charge the device again to check if there is an issue with the charging or if it was just the Optimized Battery Charging feature that kicked in to prevent the device from charging further.

Liquid DamageWhile dirt and debris stuck in the charging port can prevent the phone from charging, liquid damage can also pose a big problem. If you dropped your phone in water and have kept it aside for drying, make sure it is completely dry before plugging in the charger. Even a little bit of water can cause the connections to short and lead to even more problems.
Keep your phone aside and let it dry out completely. No matter how important the data inside your phone is or how eager you are to use the phone again, you wouldn’t want to destroy it, right?

Hard Reset/Force Restart Your iPhoneForce restart aka hard reset often turns out to be a saviour, especially when dealing with common problems. So, we are going to try it out as well.
Hard reset iPhone with face ID, iPhone SE (2nd generation), iPhone 8, or iPhone 8 PlusFirst off, press the volume up button on your iPhone. Then, press the volume down button. After that, hold down the side button until the Apple logo appears.

Hard Reset iPhone 7 or iPhone 7 PlusPress and hold both the volume down button and the Sleep/Wake button simultaneously until the Apple logo shows up.

Hard reset iPhone 6s, iPhone 6s Plus, iPhone SE (1st generation) or earlier devicesPress and hold the Sleep/Wake button and the Home button at once until you see the Apple logo.

Software UpdateMore often than not, a mere software update can help you fix several issues on your iPhone and even bolster the performance. If you haven’t updated the iOS for a while, the outdated software version might be the reason why your iPhone won’t charge. So, navigate straight into the Settings > General > Software Update. Then, download and install the latest iteration of iOS without any further ado.

Restore Your iPhoneYou should look at the “Restore” option as the last resort. You should try it out only when none of the basic tricks are working. Before going for this radical solution, you must always take a full backup of your iPhone as the restore process will wipe out all the existing data.

There’s no doubt that your OnePlus smartphone is pretty cool and gets so much done for you! Which is why, if you have experienced your OnePlus screen not Working, then it is natural to feel worried. While OnePlus is known as a ‘Flagship-killer ‘ with top of the line specs, an amazing screen, high refresh rate and low price, it is not completely immune to problems.

A number of users have complained about their OnePlus touch screen not responding properly and experiencing ‘ghost touches’ quite often. Luckily, this article talks about a few reliable solutions, using which you can easily fix your OnePlus screen not working issue. But first, let’s look at why this common hiccup occurs in most OnePlus smartphones.

Why does the OnePlus Smartphone’s Screen Become Unresponsive?Android screens have improved a lot over the past few years, but can still exhibit problems like flickering, flashing, blinking, and unresponsive touch, now and then. As far as the latest OnePlus devices are concerned, touchscreen unresponsiveness on the OnePlus 9/9 Pro or OnePlus 8/8 Pro can ruin the whole experience. But before you call the service center and decide to return the device, the OnePlus touch not working problem could be something other than a hardware issue. It could be due to many reasons such as a worn-out screen guard, cluttered storage or even screen damage. So, if you ever run into a touchscreen not working problem on your OnePlus device, you should take a close look at these above-mentioned aspects. Now, it’s time to check out the solutions.

Simply Restart Your SmartphoneThe first thing that you should do to fix the touchscreen issues on your OnePlus device is to restart or reboot it. Many a time, a simple restart can come in super handy in resolving common problems. So, do not fail to give it a shot .
Simply hold down the power key and then choose the Power Off option. After that, wait for a few minutes and then hold down the power key again to reboot your device. Once your smartphone has restarted, check if the touchscreen has started to work normally If it has, it’s time to get on with your life.

Simply, hold down the power key and then choose the Power Off option. After that, wait for a few minutes and then hold down the power key again to reboot your device. Once your smartphone has restarted, check if the touch screen has started to work normally. If it has, it’s time to get on with your chore.

Remove the Screen GuardIf the touchscreen continues to act erratically on your OnePlus smartphone, remove the screen protector. If the screen guard is worn out or made of cheap material, it could be creating a problem. Besides, do note that dust and smudge may also be preventing the touchscreen from working smoothly.
Clear the Cache of Your OnePlus Smartphone This means, wipe out all the redundant files on your device, including the photos, screenshots, videos and notes that are no longer needed. Also, do not spare the outdated and unnecessary apps, as they could be causing the problem.

Update All Apps and GamesIf the touchscreen trends to become unresponsive inside specific apps, the problem could be with those apps and not your device. So, try updating all the apps on your device. Head over to the Google Play Store > Profile > Manage apps and device > Updates available and then update the apps.

Hard Reset your OnePlus DeviceIf the touchscreen seems unresponsive even after you have wiped out all the unnecessary data, then go for a hard reset. Hard resetting a OnePlus device is quite easy and can solve the issue.
Press and hold the Power and Volume Up button to force your device to shut down. After the phone is switched off, wait for a few moments and then hold the Power button for about 15 seconds or when the phone vibrates and starts booting up. If the phone doesn’t restart on its own, then try pressing the Power button for a couple of seconds more.

Once you have all the backup, power off your device and then hold down the volume up, home and power buttons all at once until you see the OnePlus logo. Now, the Recovery mode screen will appear. Click on Wipe Data/Factory Reset and confirm—use the volume key to scroll and use the power key to confirm the action. After that, reboot the device.

Reset App PreferencesApps and software can also be a reason behind your OnePlus screen not working. If you are unable to pinpoint which app is causing an issue, you can try to reset the app preferences to see if that fixes the issue. Here is how you can do it:
Step 1: Go to ‘Settings’
Step 2: Navigate to the ‘System’ tab
Step 3: Tap on ‘Reset Options’
Step 4: Tap ‘Reset app preferences’ and then choose ‘Reset apps’
This process doesn’t delete any personal data saved for the app, meaning you won’t lose any game progress or past chats. It will reset the app permissions, VPN configurations, clear all paired devices, reset app notifications, delete Wi-Fi passwords, etc.

iOS comes with a built-in diagnostic feature that allows users to find hardware issues on the iPhone. For those unfamiliar with it, the diagnostic feature, which has derived the name from Kernel, is a crucial component of any OS including iOS.
When the Kernel encounters an issue or an error while loading, the problem is termed as Kernel Panic, indicating that something critical has happened to Kernel and even stopped it from loading properly. When it happens, Kernel puts the entire diagnostic information in a file named panic.ips.

With the help of panic.ips file, it becomes a lot easier to get to the root of the problem. And once you have checked the hardware issues on your iPhone with panic.ips file, finding the right solution to the issue becomes relatively straightforward That’s probably the reason why this hack never fails to impress both DIY lovers and the die-hard supertechies at Rapid Repair.

Figure Out If Your iPhone has Hardware IssuesiOS comes with a very helpful feature called “Analytics & Improvements” which lets you check if your iPhone has hardware issues. Moreover, it’s available even on old iOS versions like iOS 10, 11, or 12. So, irrespective of whether you are using an old iPhone or daily driving the iPhone 12 Series, you can use this diagnostic tool to figure out if your iOS device is facing a hardware problem.
To get started, head over to the Settings app on your iPhone > Privacy > Analytics & Improvements > Analytics Data.

Note: In iOS 10 or 10.2, navigate to Settings > Privacy > Diagnostics & Usage.
On the next screen, you should see a lot of logs related to analytics. Now, scroll through the entire list to find an entry named panic-xxx.ips. The file can be either panic-base or panic-full.

If you see any panic file, that means something very serious has happened to your iOS device, which prevented it from starting properly. Though it’s mostly an indication of a hardware failure which requires expert diagnosis and a repair to fix the issue, in some cases , it could be due to software crash as well.

Pro Tip:Though the “Analytics and Improvements” data doesn’t take much space, it’s considered better to remove them from time to time just to keep the device clutter-free.Luckily, it’s quite straightforward to wipe out the diagnostics information. To get it done, open the Settings app on your iPhone General >Reset > Reset Location & Privacy. Next up, you will need to enter your passcode to continue.

Finally, tap on “Reset Settings” in the popup to confirm.It’s worth mentioning that the process of resetting location and privacy is slightly different in iOS 15 and later. Head to the Settings app -> General -> Transfer or Reset iPhone –> Reset. Now, choose Reset Location & Privacy in the popup that shows up from the bottom.If the problem occurs less frequently or seems to be minor, the first thing you should do is restore your iPhone as new. You can get it done right from your iPhone. But be warned that it will wipe out all the existing data. So, don’t forget to back up the device beforehand via iCloud (Settings app -> profile -> iCloud -> iCloud Backup -> Back Up Now) or iTunes/Finder.

After you have taken the backup, head over to Settings app > General > Reset > Erase All Content and Settings (works in iOS 14 or earlier).
Do note that the process of erasing the iPhone has slightly changed in iOS 15 or later. You need to navigate to the Settings app -> General -> Transfer or Reset iPhone -> Erase All Content and Settings. Then, you will need to enter your device passcode to confirm that you want to wipe out your entire iOS device.

Once you have successfully erased your device, set it up as new. During the setup process, you will get the option to restore the device from a recent backup.
Besides, you can also use the Finder or iTunes to restore your device. But before going for the restore, do not fail to back up your entire device as it will wipe out all the existing data.

Side Note:In macOS Catalina or later, you will need to use Finder to restore the device. In macOS Mojave or earlier or Windows PC, you will need to use iTunes to restore the device.After you have successfully restored your iPhone, check if the problem is gone. If it has, you are ready to go.

After you have successfully restored your iPhone, check out if the problem is gone. If it has, you are ready to go. But what if the issue persists? In this case, you should contact a reliable iPhone repair center. With several years of excellent track record, Rapid Repair has come to be known as one of the best iPhone repair centers.
