Samsung recalls Galaxy Note 7 smartphone over exploding batteries

Samsung recalls Galaxy Note 7 smartphone due to exploding batteries Samsung has recalled its latest smartphone, the Galaxy Note 7, due to a faulty

Galaxy Note 7 smartphone batteryin the Galaxy Note 7 smartphone causing some phones to explode.
The Samsung Galaxy Note was originally due to go on sale in the UK last week, having been announced in August. But after multiple photos of burnt phones (caused by an explosion while charging) emerged online, Samsung has now postponed its launch date. ” 35 such incidents have been reported globally and we are currently conducting a thorough check with our suppliers to identify batteries that may be affected in the market,” Samsung said in a statement.

“However, as customer safety is Samsung’s absolute priority, we have stopped selling the Galaxy Note 7.”
The company said it will voluntarily replace existing Galaxy Note 7 smartphones with the new version in the coming week, but the company did not reveal when the new version would be available in the UK.


The 5.7-inch smartphone has some cool features, including an iris scanner that lets you hold the smartphone up to your eye and take a photo of your iris. From that point on, when you want to unlock your smartphone, hold it up to your eye and if the camera can match the eye picture in its memory to the eye picture in front of it, the phone will be unlocked. Update: Samsung has reportedly “paused” Galaxy Note 7 production after at least five replacement devices were burnt, meaning others could still be at risk of catching fire or exploding. Samsung told the BBC it was “adjusting production schedules to ensure quality and safety issues”. Airlines in Europe, the US and Australia are banning passengers from taking phones in checked luggage and charging devices during flights.

Samsung phone with poor battery life? This function is to blame

Samsung is heavily customizing its Android interface with One UI and a host of additional apps and features pre-installed. Sometimes bugs happen, such as those that affect your smartphone’s battery life. That’s exactly what’s happening now. Behind this is a feature that comes pre -installed on every Samsung phone. Samsung keyboard causes poor phone runtime

If you have installed the One UI 5.1 update on your Samsung device and are wondering why the Samsung phone battery life of your Samsung phone has suddenly become noticeably worse, you now have the answer. Samsung has confirmed that pre-installed keyboard apps with versions earlier than v5 .6.10.31 can cause higher battery consumption (Source: SamMobile). Samsung’s Keyboard app comes pre-installed on every Galaxy device by default and is automatically activated. Not only did Samsung confirm the issue, it also said that updating the keyboard app to version v5.6.10.31 will fix it. This new version has been out for a while. Typically, system apps are automatically updated over time. But if you are still affected by significantly poor  Samsung Galaxy battery life, then you should definitely open the Samsung Galaxy Store and look for updates there.


If you install the new version of the Samsung Keyboard app, your phone’s battery life should improve again. Alternatively, you can try another keyboard, such as Google’s Gboard. For example, I always install them directly on all my devices.
You need to know these Samsung tips:


Samsung has other problemsWhen One UI 5.1 was released, there were some issues with the new interface. Older smartphones receiving updates suddenly have to contend with shorterSamsung  smartphone battery life and higher temperatures. Now that the issue is resolved, the other keyboard bug should also be removed. Hopefully the error won’t show up next time I update.

Samsung answers burning Note 7 questions, vows better batteries

In a press release on Sunday, Samsung said two separate battery defects caused original batches of Galaxy Note 7 phones and replacement phones to overheat.
The first battery allegedly had a design flaw. Justin Denison, Samsung’s head of product strategy and marketing, said the Samsung Smartphone Battery casing was too small for the components inside, causing the battery to short out and catch fire. The second battery came from another supplier and did not have the same defect. The US branch said in an interview before the press conference. However, he said that in the rush to produce enough batteries for replacement units, suppliers introduced manufacturing defects that led to the same result.

The explanation clears up the mystery behind the Note 7 explosion, but also raises new challenges for the embattled company: after a disastrous few months that included two recalls and the decision to discontinue the popular model, mobile phone with good reviews) and regain your trust Sunday’s press conference marked the beginning of Samsung’s campaign to rebuild the company’s credibility, which includes an upcoming flagship Galaxy S8 phone and another Note later this year.
“This is a painful crisis for me,” DJ Gao, head of Samsung’s mobile business, said in an interview before the news conference. He called it the worst period in his 33 years at the company.
Not one but two batteries from different suppliers failed for different reasons, a strange coincidence that may surprise and dismay those looking for a single, clean explanation. On Sunday, Koh and three independent testing companies – UL, Exponent and TUV Rheinland – came to much the same conclusion as Samsung – that it was the battery that caused the Samsung phone’s Note 7’s battery problems, not the phone’s design or Samsung’s manufacturing process.


“The [Samsung-designed] electronics did not cause [battery] cell failures from either manufacturer,” Exponent chief scientist Kevin White said in a news release on Sunday.
While the Note isn’t Samsung’s best-selling line of phones, it’s an important device for the company. It’s one of two major flagships launched each year, notably the Note 7, which aims to compete with Apple’s iPhone 7 Plus, which launches in September. Samsung says its most loyal customer base across all its products is those who have purchased Note models. Just look at the thousands of Note 7 owners still on Verizon — the carrier is directing calls to its customer service department to have them hand over their phones.
Samsung expects the Note 7 incident to result in the recall of 3 million phones, costing the company more than $5 billion. That doesn’t include the blow to its reputation, which could take months or even years to repair.


You can also take a lookEverything you need to know about the Galaxy Note 7 recallSamsung kicks off CES event with Note 7Verizon may have “thousands” of Note 7 phones still in useSamsung’s biggest task this year will be to regain consumers’ trust and show customers and potential customers that its devices are safe and that the company won’t make the same mistakes again. Samsung hopes the transparency marks a good first step, its executives told CNET in interviews.
“If a company does it right, it takes an average of 18 months to turn around a reputation,” said Thomas Cook, a professor at Georgetown University’s McDonough School of Business. “Samsung is on the road to recovery. I think it can be Done.So, what exactly happened?Soon after the Note 7 went on sale in mid-August, users reporting overheating issues. Samsung initially linked the problem to a defective battery and recalled all Note 7  battery phones on the market., this did not solve the problem and the replacement unit also overheated. Samsung issued a rare second recall in October and stopped production of the Note 7. The focus then turns to identifying the problem.


Samsung has devoted significant manpower to responding to the Note 7 investigation, among other challenges. It has established a testing facility in each of the four locations where its phones are produced: Gumi, South Korea; Hanoi, Vietnam; and Huizhou and Tianjin, China In total, these sites tested more than 200,000 Note 7 devices with batteries and more than 30,000 batteries. Samsung’s mobile division has more than 700 engineers dedicated to the testing process. (Samsung has more than 70,000 engineers across the company, but they’re spread across various divisions.)
Engineers studied software, hardware, manufacturing processes, quality and assurance testing, and supply chains. They looked at issues such as whether iris scanners or software algorithms were causing overheating, or whether fast charging of the device could be causing overheating. ng capabilities come into play.

Samsung is turning its focus to the Samsung battery itself. Throughout the testing, engineers were able to cause the battery within the device and itself to overheat.
Samsung has two independent suppliers for its  Samsung cellphone Note 7 batteries, which are custom-made for the Note 7. It specifies characteristics such as voltage and physical size. It’s then up to the suppliers to design and build the cells however they see fit. “If you open Battery A and Battery B, they are different batteries,” Denison said.

In the first supplier’s battery, known as Battery A, Samsung discovered a design flaw that caused the battery to short circuit. The supplier manufactured a bag (the battery’s casing) that did not have enough room for the battery to expand and contract during normal charge and discharge cycles. This causes the positive and negative terminals to come into contact, causing the battery to short out.


(Some early reports speculated that Samsung phones would have no room for Samsung phones batteriesthemselves. That was not the case, but Samsung plans to create more battery space inside its devices in the future.)


For B batteries from Samsung’s second supplier, the defects were related initially to manufacturing and quality issues. The supplier supplied cells that worked well in early Note 7 devices, but the battery maker made a mistake when Samsung increased orders and forced the supplier to become its sole battery supplier. The ultrasonic welding process left some protrusions that caused the battery to short out.
Samsung has asked a second supplier to produce about 10 million new batteries. “Ultimately, they weren’t able to produce a quality product,” Denison said.
What is Samsung doing now?One of the biggest problems Samsung faced during the Note 7 fiasco was that its quality and assurance process (the testing a phone goes through before it’s sold) didn’t catch problems.


Samsung had to X-ray the A battery to find the problem, while the B battery required Samsung to take it apart to find the error. Koh said both steps are not part of Samsung’s normal testing process and are handled by the battery manufacturer. Samsung is now changing its testing process for key moving parts. For b Samsung batteries in particular, Samsung is developing an eight-point inspection process. Some of the previous steps were handled by their vendors; some are new.

One of the checks is a durability test, which checks whether the battery has been overcharged, punctured by nails, or exposed to extreme temperatures. Samsung will visually inspect each battery and conduct X-ray testing to check for abnormalities. Conduct large-scale charge and discharge tests on the battery to simulate consumer accelerated use scenarios, and disassemble the   Samsung battery to check the overall quality. Other tests will look for leaks in battery components and throughout the device, or any changes in voltage during the manufacturing process.

Samsung Is Giving A Surprise Battery Boost To Galaxy Phone Owners

Not only are Google Pixel owners getting new battery health tools, Samsung is also planning to add newGalaxy phone batteryprotection methods to the upcoming Galaxy S24 and current Galaxy phones.


Spotted by Tipster Tarun Vats on Twitter/X, the updated Phone Battery Saver feature will add three new options to extend the life of your phone’s power pack. The options boil down to “Basic Protection,” which stops charging at 100% and doesn’ t resume until it drops to 95%, rather than constantly charging to stay at 100%.
The other is adaptive charging mode, which slows charging down to 100% until you wake up. It learns your routine for doing this and provides “moderate protection” according to instructions in the functions menu.


The last option, “Maximum Protection,” stops charging completely when the battery reaches 80% and won’t resume until the phone’s battery drops below that value. Currently, some Samsung phones offer a single Samsung phones battery protection feature that stops charging when the battery reaches 85%. These three new tools will give Samsung users the option to limit battery degradation.


Samsung insider confirms three surprising Galaxy S24 Ultra decisionsSamsung offers surprise free offer to every Galaxy S24 ownerSamsung Galaxy S24 details leaked prematurely, possibly by accidentIf these tools sound familiar, Apple has also updated iOS iPhone 15 BatterySaver tools for iPhone 15 along with additional battery health information. Samsung’s battery protection levels are graded because the phone’s battery degrades faster when it’s charged and drained from zero to 100% (called a cycle) than when it’s fully charged.


Forbes Daily: Get our best coverage, exclusive reporting and essential analysis on the day’s news in your inbox every Sunday. A leak earlier this month stated that Samsung’s new feature is exclusive to One UI 6.1, which is expected to launch alongside the Galaxy S24 next month. But according to Tarun Vats, it can now be activated in One UI 6 by downloading an app called Activity Launcher and enabling it by searching for “batterypro”. However, Tarun said that the feature is not working properly yet, so the setting may be reserved for the next One UI update.


new wave of energy savingDue to the lack of easily removable smartphone batteries (a short-lived Android trend in 2016), companies are working to extend the life of device power packs. Google has a new set of battery health features that show the number of cycles, manufacturing date , and how much charge the battery can currently hold. Apple offers similar functionality for its iPhones, as well as somesmartphone battery protection tools. Google is making it easier to diagnose and repair its Pixel 8, promising to supply parts (including batteries) for seven years. Considering Apple, Google, and Samsung launched a similar slate of new battery health and protection features in the same year, I wonder if we’ll see Samsung offer expanded software and replacement parts support for the upcoming Galaxy S24.


Samsung doesn’t want to be the company that offers the least support. So will it match seven years of Android and security patches provided by Google? Or something closer to Apple’s (roughly) six-year promise? We’ll know more when S24 launches in a few weeks.

The real secret to better Android battery life

Attention, Android phone owners: Stronger smartphone stamina is well within your reach. All you’ve gotta do is reach out and grab it.
If there’s one question I hear more than any other here in the land o’ Googley matters, it’s how to grant oneself the invaluable gift of better battery life on Android.

Here’s the good news, though: While the notion of achieving better Android battery life may sometimes seem like rocket science, it’s actually just regular science — and the secret to making it happen actually isn’t all that difficult at all, once you understand the mechanics around it.[ How to switch from iPhone to Android ]In fact, all it requires is a touch of careful planning.


The Android battery life mechanicsThe main thing to know about your phone’s physical battery is that it’s a limited resource that loses capacity over time.
That’s an inherent quality of that type of technology, unfortunately, and the same is true no matter what type of mobile device you’re using: The more you use it — and, specifically, the more you stress it via ongoing charging — the less power it’s able to hold, and thus the worse battery life it gives you over time.

And here’s the easiest and most effective one of all: Stop charging your phone all the way to 100% and letting it sit on the charger indefinitely.
Ask most any battery expert, and they’ll tell you the same thing: The fastest way to shortening your battery’s life and making it perform more poorly is regularly charging it all the way to full — or, worse yet, keeping it plugged in and maintaining that fully charged state for extended periods.

In human terms, the takeaway is this: Letting your phone go super-high or super-low in charge is bad, mmkay? Instead, what you want to do is stay in the middle as much as possible.
Your better Android battery life options
We’ll tackle three separate categories and associated options for boosting your Android phone’s battery life and setting yourself up for lasting stamina success:
1. For the Google Pixel owners among usFirst, if you’ve got a Google-made Pixel phone from 2019 or later — so the Pixel 4 model and up, in other words — take 20 seconds now to dig up your device’s Adaptive Charging setting:
Open up the Battery section of your system settings.Tap “Adaptive preferences.”Find the line labeled “Adaptive Charging” and make sure the toggle next to it is in the on and active position.

Android Battery Life: PixelJRThat’ll allow your phone to take a slow ‘n’ steady approach to charging when it knows you’re gonna have it plugged in for a while, like during the overnight hours. That way, at least in theory, it’ll reach the 100% mark at the end of your charging period instead of getting there quickly and then continuing to maintain that full-charge state with ongoing power pushing.


Now, notably, this feature originally worked only when you charged your Pixel between 9 pm and 4 am and you had an active alarm set for somewhere between 3 am and 10 am That’s a pretty significant limitation, to say the least.

Either way, this setup is a smart start — and leaning on it is absolutely a good first step. But if you really want to take your Android battery life to the max and allow for the best possible battery health and thus best possible stamina over the long haul, you’ll want to keep reading (to number 3 in this list, specifically).
2. For the Samsung Galaxy gangGot a reasonably recent Samsung Galaxy-flavored Androidd device?

Your phone has a similar sort of system in place that can automatically limit charging, though with a bit of a different twist:
Head into your system settings and search for the word battery.Find the option labeled “Protect battery” and tap it.Turn the toggle on the line labeled “Protect battery” into the on position.Android Battery Life: SamsungJRThat’ll stop your phone from charging anytime it hits the 85% mark, which is a sensible limit for long-term battery health and maximum ongoing stamina. That does mean you’ll have a little less battery power to work with on a day -to-day basis, but as long as you can make that work — or even do a midday top-off, if you need to — you’ll get better battery life over the lifespan of your device as a result.

3. For anyone and everyone using AndroidEven if you’re already using a battery-saving system from Samsung battery,Google, or any other Android phone-maker who offers a similar sort of setup, you’d be well-advised to consider this last step as a stamina- protecting supplement . And if you’re using a phone that doesn’t offer any sort of built-in battery protection feature, you’ll definitely want to do this:


Install an excellent app called AccuBattery onto your Android phone of choice.Open the app up and, on its main Charging tab, look for the blue slider floating off the percentage circle at the top.Slide that little blue flag left or right to land on the value you want. I’d suggest starting at 90%; if you find that works okay for you, you can then inch your way down closer to 85% or even 80% and see how you do.


With that step finished, AccuBattery will now sound an alarm anytime your phone reaches the level you set — and that’ll be your indication that it’s time to take it off the charger.

Now, the manual part of this process is a minor hassle, admittedly — but once you get used to it, it really isn’t that big of a deal to manage. The easiest way is to get in the habit of charging your phone either immediately before bed or first thing in the morning, as soon as you wake up. And, again, you can always do a midday top-off to get through the day and avoid letting your battery level drop too low (another stamina no-no , remember?).


If you really want to go all out, there are also some physical accessories that can manage this for you and essentially cut off the power for every charge completely once a certain battery level’s been reached. That’s a fine enough option, if you don’t mind dropping the extra dough and charging only in a spot where that specific apparatus is available. But I’m telling you: Taking your phone off the charger when it hits a certain point is something you’ll get accustomed to quickly, provided your schedule supports it.
However you go about it, the ultimate ideal is to keep your phone between 20% and 80% of its battery capacity as often as possible, without any extended time sitting on a charger and constantly being fed fresh power.

The same is true whether you ‘re using an Android phone battery or any other type of battery-dependent gizmo.
And with any combination of the tactics we just went over, you’ll be able to make that happen — and enjoy betterAndroid batterylife for longer than ever as a result.

Recent Developments in Mobile Phone Battery Technology

The importance of mobile phones in the daily lives of human beings can’t be denied. Their prevalence is primarily due to their efficient utility and portability, which is enabled by a compact and strong battery. To satisfy the rising demands of smartphone consumers, its battery technology is continuously evolving. In recent years, there have been numerous advancements in rechargeable batteries for mobile phones leading to increased battery life and efficiency. 


A Brief History of Mobile Phone Battery TechnologyMobile phone battery technology has evolved tremendously throughout the years. A research article published in InfoMat (Willey) has presented a thorough overview of the technological evolutions of the battery. As per the research, 1983 was a significant year as it saw the release of Motorola’s DynaTac 8000X, which employed a Ni-Cd battery with a modest 500mAh capacity.


Nickel-Metal Hydride (NiMH) batteries substituted NiCd batteries in the 1990s. NiMH batteries had an improved power density and were more environmentally friendly than NiCd batteries. Nevertheless, NiMH batteries were susceptible to the memory effect, which diminished their efficiency over time.
The transition period between 1998 and 2000 led to the substitution of NiMH batteries with Lithium Ion batteries. The energy density of Li-ion batteries was significantly greater than that of NiMH batteries, and they were immune to the memory effect. Li-ion batteries are the most common form of battery used in mobile phones today.


Solid State Batteries – A Novel Battery InnovationSolid-state batteries have been viewed as prospective future technologies for energy storage mainly due to their improved energy density and enhanced safety when contrasted to commercial operations lithium-ion batteries with liquid electrolytes.
Toyota, Samsung, and BMW are among the businesses that are developing solid-state batteries for cell phones. A United States startup Solid Power is among the top-notch manufacturers of solid-state batteries as well as Sulfide solid electrolytes for smartphones and electric vehicles Their batteries outperform traditional lithium-ion batteries due to the utilization of better-performing electrodes such as high-content silicon and lithium metal, so consumers may expect a 15-35% cost savings at the pack level.


Graphene-Based Batteries for Mobile PhonesGraphene is the 2-dimensional framework of graphite, in which one layer of planar carbon atoms is organized in the form of a honeycomb lattice. Even at absolute zero, graphene is regarded as a semi-metallic material. Graphene has four times the tensile strength of steel, is extremely adaptable, transparent, and an exceptional conductor of heat and electricity due to its bonds. These attributes of graphene make it a suitable material for both mobile phone batteries and supercapacitors.
Huawei, Samsung, and Graphene Flagship, a research project financed by the European Union, are among the corporations working on the development of graphene battery packs for cell phones.
Hydrogen Fuel Cells Based BatteriesThe utilization of hydrogen fuel cells presents a novel technological advancement with the potential to significantly transform the mobile phone battery landscape. These fuel cells function through the combination of hydrogen and oxygen, resulting in the production of water as a byproduct. Such a process renders hydrogen fuel cells an environmentally friendly and proficient energy source.


Various corporations are currently involved in the research and development of hydrogen fuel cells for mobile phones, including Intelligent Energy, a UK-based enterprise that has engineered a fuel cell that can power an iPhone for up to a week without necessitating a recharge. The organization is presently in the process of creating a commercial version of the fuel cell to cater to the mobile phone industry.


Sodium Ion Mobile BatteriesSodium-ion batteries represent an alternative to conventional lithium-ion batteries for energy storage and release, utilizing sodium ions instead. The abundance and comparatively lower cost of sodium compared to lithium render sodium-ion batteries a more cost-effective choice. additionally, sodium -ion ​​batteries demonstrate a higher energy density in comparison to NiMH batteries.
A research article published in the Journal of Physics: Energy has presented an overview of sodium ion mobile batteries. As per the research, Titanium-based oxides are regarded as highly potential and versatile anode materials for sodium batteries, given their affordability, facile processing, and lack of toxicity. These materials exhibit greater safety in comparison to carbon-based anodes due to their elevated operating voltage, which helps prevent the formation of metallic sodium plating.
Notably, a select number of corporations, including Faradion (UK), Tiamat (Europe), Altris AB (Europe), HiNa (China), and Natron Energy (USA), are currently dedicated to the development of sodium batteries.


Novel Thin Film Battery – A Game Changer for Mobile PhonesA company based in Rzeszów is aiming to revolutionize the global market with its latest thin-film battery, which is expected to have a lifespan of up to 68 years. Developed by The Batteries, this cutting-edge technology has already earned the label of ” a game changer” from the industry press, and the company plans to begin large-scale production once construction of their “pilot factory” is complete.


Polish scientists have created a battery that can charge from 0 percent to 100 percent in merely eight minutes, offering an alternative to the conventional lithium-ion batteries which have dominated the market for the past 25 years. The new technology developed in Poland obviates the requirement for supplementary chemical compounds, and as a result, the energy density of the battery has increased by almost twofold to 1,200 Wh/l.
Market Analysis and Future PerspectiveAllied Market Research has published a thorough report focusing on the market analysis and industry forecast of  iphone batteries. According to the report, the global market for mobile batteries had a value of $21.2 billion in 2020, and it is anticipated to grow to $38.6 billion by 2030, exhibiting a compound annual growth rate (CAGR) of 6.3% between 2021 and 2030.


The report highlights that the Asia-Pacific region is projected to hold the largest market share, with China, India, and Japan emerging as major players in the mobile battery market. Nevertheless, North America and Europe are also predicted to experience substantial growth, debt to a surge in demand for superior battery technology fueled by the growing popularity of smartphones and other mobile devices.


The future of mobile phone batteries appears bright, with various promising new technologies currently under development. Notably, the advancement of flexible and stretchable batteries is an area of ​​active exploration. Such batteries can be easily integrated into wearable devices and possess the ability to bend and stretch without compromising their functionality. This will facilitate the creation of novel types of wearable devices that are presently unfeasible.
In short, the recent technological innovations in mobile  apple phone batterieswill play a crucial role in the further commercialization of smartphones and modern industrial infrastructure.

How an iPhone battery works and how to manage battery health

Your iPhone uses a lithium-ion battery that degrades over time, but there is little reason to worry about battery health in a new device. Here’s what you need to know about your iPhone’s battery.

Batteries are not mysterious black boxes that power your iPhone, in fact, they are quite simple products compared to the advanced silicon they are powering. The physical nature of batteries mean that they will ultimately wear out and become less useful over time, but device owners don’t need to worry.


Understanding a little bit of the science behind batteries can go a long way in intelligently managing your device’s lifespan. Controversies surrounding iPhone relating to planned obsolescence and expected upgrade cycles can easily be dismissed as hyperbole with a little bit of knowledge.Lithium-ion battery basicsA battery consists of an anode (+) and cathode (-) separated by a generally flammable electrolyte. When a device draws power from the battery, charged lithium ions move from the anode to the cathode through the electrolyte, releasing electrons.


These freed electrons power the device and return to the cathode, creating a complete electrical circuit. The opposite occurs when charging the device — electrons are passed into the anode and move to the cathode.
Without getting too technical, these two chemical reactions are imperfect and introduce heat loss and wear to the battery. The lithium material slowly depletes, oxidization reduces usable surface area, and filaments grow from battery plates. All this leads to cell degradation and eventual battery exhaustion .


There is nothing a user can do to stop this process desolately. Take using fuel in a car, for example, it eventually runs out. However, exhausting a lithium battery takes a great deal of time and can be mitigated somewhat by user and software behaviors .
So, when a new iPhone has a 100% battery rating, it has all of the rated milliamp-hours of power available when fully charged. It also means the battery can provide enough power to the CPU at peak current draw without issue.
Apple says its batteries are designed to retain up to 80% of their original capacity at 500 complete charge cycles. A charge cycle is defined by a complete drain of the battery to zero, followed by a complete charge to 100%.


This expected battery life can vary from user to user. The average user is expected to keep their battery health north of 80% for the first two years with regular use. Hitting 80% within a year is cause for concern, and Apple will replace your battery for free with AppleCare or for a fee without.


Others who use their iPhone constantly and charge their device from near dead to 100% multiple times a day will see their battery degrade faster. Looking at your Screen Time will reveal if you’re unconsciously overusing your device — maybe it’s time to put down your iPhone if TikTok shows multiple hours of use in a short time.
Of course, iPhones are bought to be used. But, like anything, moderation is important, especially if you’re worried about something as physical as battery chemistry.
Ultimately, once the battery degrades below 80% of its original capacity, protections within the operating system will engage to ensure the device doesn’t shut down inadvertently. This throttling can be avoided by having the battery replaced at an Authorized Apple Service Provider.


After the iPhone throttles the processor for the first time to prevent a shutdown, a new toggle will appear in battery settings. This gives users the ability to turn off the throttling feature and allows the processor to draw full current.
However, the device will shut off as soon as the current draw exceeds what the battery can provide. It is highly unadvisable to turn off the throttling feature and can lead to battery damage.


Degraded batteriesBefore iOS 10.2.1 in 2017, the iPhone didn’t do much to account for aging batteries in its software. However, a perfect storm of circumstances set AppleBattery up for user complaints about inadvertent shutdowns in older devices.
Recent devices had more powerful processors, thinner designs, and brighter displays. These factors led to smaller batteries with lower capacities that died faster. A smaller battery also meant a lower peak voltage, which meant aging batteries would dip below peak rated voltages sooner.
Those factors were coupled with more people buying iPhones than ever, then keeping them for longer than expected, which led to more reports of batteries becoming exhausted. Note that the “Plus” models and iPads were not encountering shutdown issues thanks to their larger battery capacities .


Intermittent shutdowns were reported by owners of the iPhone 6, iPhone 6s, and iPhone SE. Users complained that the device would show battery levels of 30% or more then suddenly shut off as if the battery died.


This occurred because these devices’ batteries had been exhausted to the point that they could no longer provide peak power during peak CPU draw. Since there were no other protections in place, the iPhone would sense the CPU power draw exceeding the available current and just shut down to protect the iPhone battery.

We spend so much money on tech that it’s incredibly frustrating when our devices break. A little prevention can go a long way. Here are six checkups to give your tech now to avoid a shocking repair bill later.


Then there are the mistakes you make day in and day out. Bad charging habits can shorten or disrupt your smartphone battery life if you aren’t careful.
Don’t rely on knock-off chargers
High-quality chargers have circuits inside of them that switch off when there’s too much power draw. This protects your phone battery from overcharging, breaking, or overheating your phone.
Heat is your battery’s biggest enemy. Some cheap chargers and cables have even led to fire and injuries. Saving money is great, but don’t skimp on quality here.
Here’s a list of safe options that will charge your phone safely.
Be careful with power banks
Just like with cheap chargers, cheap power banks can ruin your battery over time. Be sure any power bank you use has overcharge protection. If not, you can still use it, but keep an eye out. Once your battery is almost full, unplug it.


It would be best if you avoided also power banks with quick charge options unless they’re from a reliable brand. Here’s a rule of thumb: If you’ve never heard of it, say no.
Rapid charging can send too much electricity to your phone and cause battery damage. This high voltage could, at the very least, shorten your Smartphone Battery lifespan.

Don’t download battery-draining apps


Lithium-ion and lithium-polymer phone batteries only have a limited number of charging cycles before they degrade. This is why most people encounter battery problems after two years of use.
There’s nothing you can do about your battery wearing down eventually, but some things have more of an impact. If you have performance apps that monitor your battery life, they could harm it in the long run. These apps constantly use power to monitor your battery life.


Spyware, adware, and other malware are also taxing on phones. Most constantly run in the background. Tap or click here for signs your phone is infected.
Don’t use your phone while it’s charging
Your phone is at 1%, so you plug it in. Leave it alone! Using your phone while charging can rapidly increase the temperature, putting strain on your battery, screen and processor.


Charging rules are essential when it comes to your computer, too. Tap or click for steps to check your  battery health.
Take it out of the case
Phone cases can be a great way to customize your phone and add some physical security. When it comes to charging, though, they can cause temperature problems.
When your iphone battery heats up too much, it can cause damage to the rest of your phone. To be safe, take the case off while you charge iphone battery especially if you notice your phone heats up while it’s plugged in.
