Why Does My iPhone Turn Off When I Still Have Battery Life Remaining? Here’s The Real Fix!

I’m going to tell you why your iPhone, iPad, or iPod suddenly turns off when you still have 30%, 50%, or any other percentage of battery remaining and exactly what to do to fix the problem, if it can be fixed. I’ll use an iPhone in this article, but if you have an iPad or iPod with this problem, follow along — the solution is exactly the same.

I’ll be honest right off the bat: I can’t guarantee we’re going to be able to fix your iPhone. Sometimes, issues related to iPhones randomly shutting off are caused by water damage or other unfortunate accidents. But don’t lose hope! A lot of the time, you can fix this problem at home.

I’ve Got A Faulty Battery, Right?

Not necessarily. More often than not, what’s actually going on is that your iPhone isn’t talking to the battery correctly. Your iPhone’s software is in charge of monitoring the amount of battery life remaining on your iPhone. If the software or firmware isn’t communicating properly with the battery, it’s not going to display the right percentage.

Just like apps on your iPhone, your iPhone’s firmware can have glitches, too.

Wait. Isn’t This Deeper Than A Simple Software Problem?

Yes. This isn’t your simple run-of-the-mill software problem where your battery is draining too fast because your apps are crashing. But it’s not necessarily a hardware problem either — so we need to address your iPhone’s firmware. So what is it? If it’s not “soft”-ware, and it’s not “hard”-ware, then its “Firm”-ware.

The Fix For iPhones That Turn Off With Battery Life Remaining

To fix the issue with your iPhone shutting off even though it says there is still battery life remaining, we’re going to do a “DFU Restore”. DFU stands for Device Firmware Update.

A DFU restore reloads your iPhone’s software and firmware, so it’s an even deeper type of restore than putting your iPhone into recovery mode. Check out my article to learn how to DFU restore your iPhone! Afterwards, come back here to finish up.

Your iPhone Needs Time To Recalibrate

Now that your iPhone is good as new and all your apps are downloading, give your phone a few days to recalibrate and get to know the battery again. I recommend fully charging your iPhone and letting it fully discharge a couple times before declaring the problem officially fixed or not.

When You’ve Tried Everything Else

If the issue comes back after you’ve done a DFU restore, you’ve eliminated the possibility that a software or firmware problem is causing your iPhone to turn off with battery life remaining or, in some cases, to randomly jump from one percentage to another. If that’s the case, you may need to repair your iPhone.

Repair Options

If you go through Apple, you can visit a local Apple Store (make an appointment first), or begin the repair process online. If you’re looking for a less-expensive option, I recommend Puls, an in-person service that can arrive in as few as 30 minutes to replace your battery, and offers a lifetime guarantee on their work.

Some people try to use an external battery pack like the ones you’ll find on Amazon as a temporary stopgap, but if your iPhone is damaged, it may not help at all.

Wrapping It Up

Thanks again for visiting Payette Forward. I sincerely hope this article helped you stop your iPhone from turning off when it still shows a percentage of battery life remaining. I wish you the absolute best of luck and hope to hear from you! If you have any other questions, the UpPhone Help Forum is a great place to get answers.

All the best,
David P.

Hi,

I have similar problem with iPhone 5, it keeps on shutting down even though I see battery life is still there. iPhone also becomes little warm when it turns off automatically. I use power home button to shut off it permanently.When I try to start it again after 30 mins or so it works fine however shutdown again and again.

How do I fix this issue?

Dear Sofia, I apologize for taking a while to get back to you, but I did want to take the time to respond for your sake and for everyone else who might be wondering how they can make their iPhone louder. I’d like you to take a look in Settings -> Sounds. Make sure Ringer and Alerts is all the way up, and make sure you have Change with Buttons turned on. If Change with Buttons is turned off, when you use the volume buttons on the side of your iPhone to adjust the volume, the music and other sound… Read more »

Hi there. First of all, thank you very much for your precious tips.
I have a quick question though, after following these steps my iPhone is now asking me for random peoples apple-id’s passwords.

Why is that and what can I do against it?

Thanks for the information. Unfortunately, my power button is stuck down also LOL. So I’m kinda screwed. Ready for a new phone anyway.

Thank you. This has just worked for my iPhone 4 (2010). It had been shutting down at 50% or 60% – once even at 90%. Now it has run down to zero% three or four times so I think the problem is cured. Incidentally the DFU took less than 60 minutes in total (I wasn’t hurrying) and Apple’s restore mode took several hours and had not cured this particular problem. (Clearly the Apple restore must have done other things.) Also for whatever reason the phone now “feels better”. I can’t put my finger on any particular improvement (other than the… Read more »

Hi Dawn, Thanks for the great question and I hope I can help to steer you in the right direction. If you’ve already followed all the directions in this article, especially those under the heading “iCloud Backups”, you’ll need to head to Settings -> iCloud -> Backup and tap the iPhone that shows ‘This iPhone’ underneath. Turn off Camera Roll and any other apps are taking up significant amounts of data. I bet that one app – perhaps another photo or video app – is trying to back up a whole lot of data and preventing your entire iPhone from… Read more »

Thanks, David! Was having to reset (power home button) on my iPhone 4 about once a day. Tried cycling the battery, and restoring via iTunes. The DFU restore seems to have done the trick.

Dear Scott, I’m so happy that you were able to solve the problem with your iPhone 4 with a DFU restore! Thanks for taking the time to let us know it worked for you. All the best, David P.

Hi All,

I have restored a lot of phones this way and often get errors when attempting to do this when iTunes is not fully updated.

if you get an error DURING the restore process please update and try again.

Windows: From the menu bar in iTunes, choose Help > Check for Updates.
Mac: Choose iTunes > Check for Updates.

Hi! I just try that, and I can’t restore my iPhone 5. In the process, iTunes say that an error is happening. So basically, my iPhone is in recovery mode, but I can’t restore it even if I try (my iPhone is plugged all process long). What can I do? I know is not the battery and either of the humidity.

Please, I need help.

Hi
I also tried the procedure many a time but always when almost 59 minutes remaining, there is a msg that network timed out. My phone is IPhone4. What to do? Please help…

Hi, I am trying this out right now. I had already done resets using backups, and the problem still occurred. So, if the phone continues to shut off randomly, when it ‘appears’ to have sufficient battery charge, what else can be the problem? If the battery charge indicator shows a charge, is it still possible its a battery problem, or is something else causing a failure (not errors in programming)? It is a 2009 3GS that up until Jan 2014, was actually working great all this time! Loved using it as ipod/itouch device to use on wi-fi and wish I… Read more »
