Firstly, thank you for the clear article. Secondly, regarding the soft reset, I always just held the power button and swiped to power off. If I turn the phone off while charging, I keep it plugged in while powering back on just before I leave. I used to just unplug the phone and turn it on while leaving but booting devices uses a fair bit of battery power while they load all the bits up at full speed. I also do it whenever my iPad or iPhone are a bit sluggish.
It works every time! The Apple Geniuses also reset the device whenever someone has a problem. It is the first thing they do, because it fixes so many problems. I thought it could be a calibration problem and googled this subject, and I found that Apple knew about the sudden death issue and has a free battery replacement program for phones sold between Sep and Sep Go to the battery rpelacement program website, key in the serial number to check eligibility.
If YES, make an appointment with Apple. I just did this and got my battery replaced free of chrage. Just thought I share this info. After updating to iOS 8. I did as you told. Thnx man thnx a lot. Good morning. Can i using my i phone for browsing and anything, while my iphone during charging battery. That is ok or will make problem. Thank u. I advise turning your iPhone off while charging, if possible. The battery will last longer if you do that.
You can probably feel it getting warm when you use it and charge it at the same time. Heat will eventually shorten the lifespan of the lithium-ion battery. You can do it either way. Does anyone know of an app that can record a log of battery levels, say, every half hour?
I think this would be very useful for diagnosing poor battery performance, because often the drain is sudden and is associated with entering a poor reception area, etc.
I had such an app on my Blackberry, and it was very useful. If you can remember to run them to record the level, you might as well just write the level down yourself.
There are a bunch of battery life apps in the App Store. If I restored my iPhone 6 from the backup of an iPhone 5 running ios6, could that cause my i6 to skip battery percentages. The restore is only putting back apps, content and user data. Consider having it replaceed or using a DIY kit to replace it yourself. Since it is an iPhone 6, I doubt that the battery is shot. If it is, it is still under warranty. My iPhone 6 had very poor battery life for the first few days. You will experience it with a new phone and also with some iOS updates.
As I am from Pakistan and here there is no apple technicians. Kindly suggest me the possibilities so that I can overcome this problem. Moreover, the battery works absolutely fine. But still I am very much annoyed because of this. Try turning your iPhone 6 Plus off when charging. When you first get a new iPhone, it is running processes in the background to optimize and set up your device. For example, iCloud and other Apple services are synchronizing data.
Your iPhone might also be downloading an update in the background. I knew why it was happening, and after a few days and battery calibration, I now have great battery life. In fact, on the first day I got my iPhone, it went from a full charge to nothing in just 3 hours of use.
This is not unusual. The reason why your iPhone 6 Plus is not charging all the way is because the battery is draining and charging at the same time. It will eventually charge all the way. You can turn it off to remedy this. It is something that will only happen to a new iPhone or maybe after a major iOS update.
In this situation, however, I would recommend leaving your iPhone on, plugged in, and connected to WiFi. Let your iPhone do its optimization and set up. Typically, I recommend charging the iPhone while it is turned off, because it will charge faster and with less heat.
In your situation, letting the background processes run is a good idea. I also suggest installing any iOS updates. Updates usually improve battery life, as their engineers find more ways to improve operating efficiency.
Thanks alot, i followed step by step process and battery issue has been resolved, but now i have figured out another problem, that sometimes the sound in applications gets turned off automatically.
The phone recognizes that the handsfree is still intact, for that i have to restart the phone and then it start working normally. It is mostly likely a software issue, if resetting fixes it. It is also possible that a third-party headset might have an irregular jack. This could prevent the iPhone from recognizing that the headset has been plugged in or removed. Thanks for the information. But I have a problem with my iPhone.. Currently I am in Sweden up north where it is really cold. What you are experiencing is normal and to be expected with any lithium-ion battery powered device.
Cold weather is known to temporarily affect lithium ion battery life. This is why you see it decrease so rapidly. If you turn it on too soon, there could be a problem with condensation. This is true of every electronic device, and most of them have warnings in small print. Given the metal housing of the iPhone, it should get up to temperature within a few minutes.
Just feel it to make sure. It is just a reality of physics and material science. The newer iPhones are metal, which dissipates heat. Unfortunately, this means they are less suitable for cold weather than their glass-sandwich predecessors. Heat is usually a bigger problem than cold for smart phones.
This is actually a great idea for an upcoming tips article. For now, here are some tips that can help:. Keep your iPhone in a pocket that is close to your body or inside a jacket. Turn your iPhone off not just sleep if it is extremely cold.
Make sure that your iPhone has warmed up before turning it on again. Consider purchasing a case that insulates your iPhone. Neoprene seems ideal, as this is the same material used in wetsuits. You can probably find a case that is designed specifically for cold weather. I think condensation on the corroded parts caused short circuits. It is due to the laws of physics, which apply in Sweden.
Ions slow when tempertures drop. This is why ice is a solid. Lithium-ion batteries can only operate at a certain temperature range. When it is too cold, the ions no longer move freely and the battery cannot produce current. What you suggest is also possible, but this sudden drop in battery life is a well-known issue with all lithium-ion battery-powered devices.
I suspect there is no permanent damage, as it works fine under normal operational conditions. The physics and real-world evidence are convincing enough for me. Calibrating the battery will remedy exactly what you are experiencing. As mentioned in the article, you might want to let it sit overnight after it has turned off. This will drain the battery further. Calibration fixes this problem with battery metering inaccuracies. I only do the calibration as needed.
Otherwise, I usually recharge my iPhone regardless of remaining battery life. The reset mentioned in the article just clears some cached data. Hii I am using ios7. Follow the steps for battery calibration. This is exactly the problem that calibration can fix. First, make sure to calibrate the battery as outlined in this article.
This should improve battery life. Also, make sure you are connected to a WiFi network whenever possible. Cellular data uses more energy to maintain a connection, even in standby mode. I find that when I have turned off WiFi, the standby time decreases significantly. You can also do some performance tuning that will speed up your device and help with battery life. There are all sorts of bells and whistles turned on by default on iOS 7 or later. Most notably, app content refreshes and automatic app updates can drain the battery, even in standby mode.
Thanks for the calibration tip! Your opinion would be greatly appreciated. BTW, I do all the steps to keep unwanted battery usage down, e.
On my iPhone 6, I typically get hours of usage with days of standby time. This is with WiFi turned off cellular data uses more energy, even in standby mode. When I first got my iPhone, the battery life was poor for a few days.
It is running some processes to optimize the iPhone, such as Spotlight indexing and iCloud transfers. In fact, I remember seeing it go from a full charge to shutting off in 2 hours. If you continue to experience poor battery life after several days, it could be a faulty battery.
Some apps are known to gobble battery life, due to poor design. You can see the percentage of battery life each app is using.
App updates may solve the issue, but if the app is just poorly designed, you may want to consider finding an alternative.
The alternative would be to just use the web version. I do everything I can to save battery life like reducing screen brightness and so on. Your opinion would be greatly appreciated,. I know this page is about recalibration, but I wonder if these things should be kept in mind, and recalibration only done when necessary. I have been doing this with my iPhone 4 for years, with no battery life problems.
In fact, I still get the expected battery life on my iPhone 4. I continue to do this with my iPhone 6. The Gizmodo article is about smartphones in general.
This is not true of the iPhone. In fact, I feel this article misinforms people. For every day non-calibration charging, you can charge at whatever percentage. The booklet that came with my iPhone 4 instructs users to run the battery fully down at least once a month. Apple used to have this information on their site. You may get it fixed at an Apple Store or buy a new iPhone. MacWorld offers the same advice I do tip 30 , and mentions that Apple recommends draining and recharging the battery once a month.
I will try to find my iPhone 4 booklet and scan in the page with the information. You can charge your iPhone at any time, regardless of the percentage of battery life left.
However, when you calibrate it, you should run the battery down until the device powers off. In theory, this would keep the battery cooler. I never did this with my iPhone 4, and after 4 years, it still offers the expected battery life. I did, however, calibrate the battery regularly. This is not just for the iPhone. I have a family member who always plugs rechargeable devices into chargers when not in use.
The batteries in these devices are completely dead within years. The reason why, according to my research, is that ions do not move freely within the entire battery. This is why Apple mentioned people should drain and re-charge the battery monthly. They no longer mention this because it could be the next Apple-gate. Their battery technology has not changed.
The laws of physics have not changed. This is still true, although it does not help profitability. That's not true at all. They don't even provide a reason, theory or rationale for this. I don't mind the challenges, but they seem a bit asymmetric. I wonder why you so readily accept Gizmodo's claim, which is truly ridiculous?
Not only do you not question it, but you provide it as advice. The article isn't even well-written. It has sentence fragments, run-on sentences and doesn't even seem to have been proof-read, let alone fact-checked: "Well forget all that. Right now. It is a sentence fragment. For some time, I was wondering if you were giving me a hard time, or honestly challenging my advice. Now I know. My iPhone5s 8. Please help me! I think that logic board or battery damaged by a pressure to frame.
Does calibrating has eny influence!? Yes, calibrating can often fix problems like this. It is still under warranty. Hi, thanks for your tutorial and time for answering. I had to change the battery of my old iPhone 3GS used by my daughter. Is there a way to force the charging again? Thanks a lot. So this is a brand new battery that you had installed in an iPhone 3GS? It seems like the battery is faulty. Try having it replaced — it should be under warranty. Keep in mind, it can take several minutes for the iPhone to show it is charging, particularly if the battery has been depleted.
Hi, I am jailbroken on an iPhone 6 plus and have been expieriencing major battery life issues. I just got my phone last christmas and it only lasts me about a day maybe less.
And it charges remarkably fast too. I dont want to unjailbreak because I cant live without it.. Will calaborating my battery fix my drainage issues? I uninstalled every cydia tweak I have so im basically jailbroken but dont have any extensions on my phone. Please give me some advice or tips. It could possibly void the warranty and it could put you at risk for installing malware. Calibration may solve your battery issues. Keep in mind that jailbroken devices can have more processes running in the background.
This will drain battery life faster. Perhaps someone in the jailbreaking community has some tips on tuning the OS to be more battery-efficient. I calibrated my iphone 5s but percentage is wrong again. You may want to look at doing some tuning to improve battery life. The battery can charge beyond this. I still notice this happens, even after calibration.
Thanks for your answers!! I replace my old 5S battery because it drains in just 3 or 4 hours. Actually, I have exactly the same issue with the new battery.
Still decreasing in a 3h or 4h in sleep mode. What can I do? I have the same issues with my iPhone reset to factory original settings. I think this is an iOS configuration issue. My hunch is that you have your device setup to use a lot of the auto-update and content refresh features.
These are turned on by default. If you have installed a lot of apps that update content frequently, your device will be doing a lot of work in the background, even when it is in sleep mode.
Try disabling these features and you should notice a difference. I have an article on how to speed up iOS 8. You can follow this to turn off auto-app updating and automatic content refreshing. This will have the effect of only updating Facebook, for example, when you launch the app, instead of constantly updating it in the background.
There are many other apps, particularly news and social media, that take advantage of the automatic content refresh. Really, the auto app updates and content refresh are the most likely the culprits.
The other possibility is that you live far from a cell tower and this may require your cellular antenna and components to use more energy. When I get my hair cut, the salon has really bad reception, and I notice my iPhone gets warm and the battery drains fast. It must work much harder to maintain a cellular connection. If this is the case, even using the device in WiFi mode may not solve the issue, as your phone is still pinging the cellular network to receive phone calls.
At best, it will amerliorate the issue. You can test this theory by putting the device in Airplane Mode. Also, if you are only getting a few bars of reception, then it is definitely contributing to the drain.
I get very good battery life on my Verizon iPhone. With my 5S and the auto-update and content refresh features off everything off , still happens the same. Does it have to be in charge for atleast 5 hours. The iPhone can be charged for more than two hours. Five hours will ensure that the battery is fully charged. And problem still exists. Do u think restore can fix that? Revert soon. When your phone turns off, the battery is drained. Following the steps in this article should fix this issue.
If not, there may be a problem with the battery. You may need to replace it. Or is that for calibrating purposes only?! Also, should I charge my iphone everyday, or at a certain percentage? I try to do that, but it is not necessary. It is not even necessary for calibration. I recommend it because it will prolong battery life. I will sometimes leave my phone on and charge it while updating apps.
For the most part, I do shut down my iPhone when it is charging. I maintain this practice with my iPhone 6. The thing is, you want to keep your iPhone from getting warm.
I know people who will charge their phone while playing video games for hours. The phone becomes uncomfortably warm. The designers expect normal use, not 12 hour Candy Crush marathons. If I am playing a video game and my iPhone starts getting warm, I will put it in sleep mode and put it down on a metal table.
The whole idea is to not get your iPhone too warm. Check out Optimal. The designers provide a lot of information about heat damaging the iPhone. It will definitely damage the battery. It also seems to be causing some users to permanently damage the WiFi module. Great tips appledystopia, btw is it worth it to download the lastest IOS 8. Or it would kill my battery lifespan again because 8. Some batteries may not recover and cannot be recharged. Hey Kappy I wanted to let you know if you don't already that number 3, 4, and 5 are different links, but all three lead to the same website.

You can check its progress at any time in the battery health section of your iPhone settings. According to Apple , the recalibration capability for the iPhone battery is only available on iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max to address inaccurate estimates of battery health reporting for some users. From the home screen, tap Settings. In the settings menu, scroll down. Tap Battery.
Tap Battery Health. Look for Important Battery Message at the top of the display for information about the battery recalibration process on your phone. The calibration process is automatic, and it can take a while. The battery calibration tool introduced with iOS As it recalibrates your battery, you will see your Maximum Capacity and Peak Performance Capability change to reflect the actual status of your battery.
This process requires you to fully drain the battery, which can be harmful to lithium-ion batteries like the ones found in iPhones. With that in mind, you should only use this calibration process if your battery life is already low, and you should only do it occasionally.
If you only calibrate your battery every few months or when your phone needs it, the benefits you see from calibration should outweigh the potential harm done by allowing the battery to die completely. If your phone has an automatic calibration tool, do not use this process. Allow the calibration tool to do its job, even if it seems slow. Use your phone until it shuts off due to the battery running down. Leave it alone for at least three hours, or overnight if possible.
Plug your phone in using the original cable and charger or a cable and charger that are Apple-certified.
