iPhone 5S getting incredibly hot and high battery usage after iOS 8 update

Hey everyone,
This is the first problem I have ever had with my iPhone.

I own an iPhone 5s and updated to iOS 8 late last night, my phone was fully charged this morning and is now down to 42% after only 1 Hour 37 Minutes of usage...

My battery life could last me a whole day (anything between 6 and 9 hours usage time), so this is a huge issue.

I have also had to remove my iPhone from its case and even turn it off in order to let it cool down, it got hot enough to feel through the case.

I am extremely disappointed as I was looking forward to the iOS 8 update,
and now all I am encountering.

Any suggestions is issues.or advice?

iPhone 5s, iOS 8, Public Release.

Go into settings and find out which app is draining the battery. Settings -> General -> Usage -> Battery Usage. The app that is using the most may not be compatible with IOS 8 and will have to be removed or updated.

Thanks for responding,
The top 3 apps currently are:

Settings at 25%
Home & Lock Screen 18%
and Facebook 17%

(However Facebook is as up to date as it can be, I updated it just before the iOS update).

this is with 25% remaining and a usage time of 2 Hours 26 Minutes.

So I've run my phone right out of battery now (so it turns off) and the last record I got was at 1/2%, they were as follows:

Usage: 3 Hours 30 Minutes
Standby: 10 Hours 25 Minutes

Battery usage percentages:

Settings: 25%

Home & Lock Screen: 20%
Facebook: 15%
No Mobile Coverage: 8% (which is expected as there is only signal in 2 spots in my house)

Messages: 6%
Safari: 5%

Mail: 4%

Phone: 4%
Twitter:3%

App Store: 3%
Snapchat: 2%
Instagram: 2%
Photos: 1%
Calculator: 1%
IMDB: 1%
iTunes Store: 1%

Anyone got any views on this?

Baring in mind I could get between 6-9 hours Usage on top of 10 hours Standby on iOS 7.1.2.

I am having the same issues! I recently updated to iOS 8 on my iPhone 5S last night, prior to the update my battery was working just fine but after I updated to iOS 8 I noticed my battery life change and drain more quickly after minimal use.

Hey dubs24 and phoenix99tm,

kentuckyman78 seems to be the one one who's been able to get through to Apple about the matter,

hopefully he he will get a response soon and we can all be free of battery draining.

I completely agree.

charged my phone up from dead (turned off) to full 100% and had a 1 hour phone call with my partner (which isn't uncommon) and my battery is already down to 70%, the phone call was with everything off but what I needed to call (so no WiFi etc.) and its already down to 70%.

With iPhone 5s specifications suggesting I could get up to 10 hours call time (therefore suggesting 10% per hour of call time), loosing 30% is triple that rate, suggesting our batteries are being drained at at least 3x what they should be.

Another quick update for everyone.

I have successfully depleted my battery for a second time, this time I only got 3 Hours (and about 9 Minutes) usage.

Things are getting worse and the phone is getting hotter, I hope this is sorted ASAP before phones get damaged.

My 5S is behaving fine, but there are some bugs, battery life is shorted byt not by much and thats to be expected. Have you tried a soft reboot? Hold power button and home button till the apple logo appears? If that does not fix it I would suggest aclean install and start from scratch, don't use a backup as that may have some corruption causing this issue maybe. Hope it gets sorted out

thank you for replying killhippie,
I have tried the soft reboot and am still having the same issues.'

I'd prefer not to re-install, because that shouldn't have to be the case after installing the software,, but if Apple provides no solution, then I may have to.
