Hi. Try to follow the instructions on this page in order to maximize your battery life: https://www.apple.com/batteries/maximizing-performance/

Try to reset your device. This won't delete your data stored on the phone.

• Press and hold the Sleep/Wake button
• Press and hold on the Home button
• Keep holding both buttons until the display turns off and back on with Apple logo on it.

You may also try to reset all settings: go to Settings - General - Reset - Reset All Settings

You may also try to follow these steps:

1. Navigate to settings/general/ battery usage. Check the applications. This will show you which app eats up your battery.

2. Turn off iCloud keychain: Navigate to Settings/ iCloud/Keychain / turn it off.

3. Limit apps activity on the background: Navigate to Settings/ general/ Background App refresh/ turn it off for each application which uses to much power.

4. Disable auto brightness: Navigate to settings/ display and brightness/ auto-brightness. Turn this option off.

Same problem, a big battery drain in my iPhone 6, an hour ago it was 96% ..I did not use the phone, and now, I'm at 92% !!

IPhone 6 guaranteed me a good autonomy, finally I was happy,and now the battery has returned to make despair as in previous models.

An update disastrous 😠

I don't know if this will help anyone else, but my phone had lots of issues but this helped:

1. Sign out and then in to the iTunes & Apple Store in the phone settings. Settings > iTunes & App Store (Tap your Apple ID)
2. Turn off "Show Apple Music". Settings > Show Apple Music (Toggle this to off)

   I turned on "Show Apple Music" this morning, and haven't had any issues.

Hi,

I have an iPhone 5/ 32GB. My iPhone started acting really quirky and doing the same as you described. In a perfect world I would only have iPhone problems! Vehicle wouldn't start on the way home, iPhone won't turn on and get's extremely hot then reboots itself. I finally got home synced the iPhone, went through all the resets as described and still nothing. I tried to restore, but the iPhone would not stay on long enough to restore from my MacBook.

Last resort for personal attempt to fix it, I followed these instructions and the problem went away:

• Press and hold the Sleep/Wake button
• Press and hold on the Home button
• Keep holding both buttons until the display turns off and back on with Apple logo on it.

The iPhone appears to be working fine now. It's charging without rebooting from the MacBook and it is no longer over heating.

Best wishes,

If all else fails say a little prayer and run through it again. I was just about to throw mine into a wall, really frustrated.

I had great battery life on my 6+ before the update. Now my battery drains incredibly fast say 100-0% in an hour with the same use as before the update when my phone would be above 20% at 12am. Please fix it apple.

I am having the same issue. I really don't feel like paying $80 to have the battery replaced, only to find that it was a software problem.

My 5s has had great battery life, and I cannot believe that it would become so bad, so fast. It will drop from 60 to 20 to 1 and then shut itself down, all in the space of a few minutes.

I had to tell my corporate IT guy NOT to update the iPhone I use for work, because I'm worried that the same will happen to it.

I Navigated to settings/general/ battery usage and found that "Maps" that I have not opened was using 63% of my power. I cannot delete this app. I think we need a patch. I set location services and updates for this app to "never" and I will see if that helps.

Mine said that Facebook was using 50% in the last 24 hours for "background activity".

And "Mail" was in second place at around 25% with "low signal". I have an AT&T micro-cell in my house, so I'm not too sure about low signal being a real thing.

I'm downgrading to 8.4 as we speak.

Downgrading has already improved my circumstances. The phone has lasted over 1.5 hours without needing to be plugged in, which is more than I could say for it yesterday.

Yes, I tried all of the voodoo tricks like backup/restore, and turning off trivial features that use batteries. None of them worked.

8.4.1 is a total dud, at least for me on my device.

I had a great battery life on my iPhone 5S when it was running in iOS 8.4 but the moment after its update to iOS 8.4.1 the battery is draining pretty fast. The iPhone gets heated up when kept for a while and the battery just goes from 100 % to 80 % in no time.

Waiting for Apple to rollout a new Update that #Fixes the same 😟.

I also have a 5s that's been fabulous since new. I'm not having overheating problems now but have in the past. A hard reset always worked for me.

Today however, after updating to iOS 8.4.1 I had a strange occurrence. I went to send a text but my phone was dead. I thought this strange because just a few hours earlier (with little use since) I had 80% battery. When I got home I plugged it into the charger and nothing happened . I held the home button and the top power button together and still nothing. Uh oh. I went to move away from the phone and I got the  boot screen. Once it went through that sequence I was presented with the familiar screen to enter my password. I looked at the battery and it was charging but showed 56% charged!!!

i Don't know what's going on here but I am pretty confident that this is an 8.4.1 issue.

I hope it doesn't happen again but at least my phone isn't the brick I feared.

Ok, I realize this may come off as pure madness but it seems to be helping me.

My 5S was heating badly as well lately (after the last update) and draining battery (with home screen somehow being the main battery eater in the last 24 hours in which I was actually browsing a lot with weak signal), I was desperate to find a solution. Now, I have tried resetting the network settings (didn't help a bit) and then all settings (helped at first, but then, when I started bringing my usual settings, passcode and touch id in, the phone started heating up badly again). And then it kinda dawned on me - touch ID. I have disabled it and the crazy battery drain (was about 1% per minute) stopped and the phone hasn't been heating up for the last ±20 minutes. From 80% it only went to 79% and I have shot a 20-second video, messaged online for ±3 minutes and sent the mentioned video over wifi to my friend between 80 and 79.

Would be great if this were the true root of the problem.

I logged in specifically to write this reply.

I just put the new update-iOS 8.4.1- on my iPhone 5S on Friday(8-21-15). I went from getting decent battery life to the battery draining in a couple of hours.

Also, my wi-fi connection has been intermittently breaking up. Those are the two problems that I have encountered so far with the new update but it's only been two days. Apple needs to fix this. I would recommend to anyone thinking about updating to iOS 8.4.1-don't do it!

I had this problem too and I guess I am having hardware issues now because of this software problem.

I had to get a new phone because of this also - shame on you apple. You should have better tested backward compatibility on all devices before making a release.

There have been lots of complaints about this, mosty on iPhone5 and iPhone 5s after 8.4.1 update 😠

I have the same issue and its caused by this. The update seems to have triggered a re-scanning (and re-upload to cloud) of all my photos. If you go into Settings -> Photos & Camera you will probably see it 'Preparing XXXX items...' or 'Uploading XXX items'. When that process completes it will calm down but it takes several days 😟
