Q: ios 8 battery drain issue and Bluetooth issues

I'm having the same battery drain issue but the funny thing is it didn't happen right away after the update. It started last week and in spite of deleting all my email accounts except icloud and turning push off on everything but reminders and calendar items, reset all settings, soft-reset, my battery still won't last the day.  I use my iphone5s minimally.  Today after 10 minutes of usage and 4 hours and 34 minutes of standby it was down to 47%.  Bought the phone directly from Apple  6 months ago and it's become a very expensive paperweight.

There are reports of the 8.1.1 beta having some improvements to iPhone5S battery life. I'm installing it now. You can to, follow the instructions at http://www.techglobex.net/2014/06/how-to-install-activate-ios-8-beta-without-reg istered-apple-UDID.html?m=1

Man this is such a pain, my wife was complaining that her battery was draining fast. Little did I realize that she had upgraded and I had not. The moment I upgraded my phone I'm in the same boat.

I did not realize its such a big issue, I would have not upgraded.

Hope Apple is working furiously to resolve this issue. We are an apple devices family...

apple are you listening? apple support put a new battery in my 5 saying that was problem, result, the broke the logic board and gave me a new phone. I was hoping this would solve my drain problems, well it didn't. I contacted customer service and they told me to take my phone back to service and have it checked out, well it checked ok and they sent me on my way.

I own 3 iphones. 2 Ipads, and all have severe battery drain problems since ios 8, 8.1, 8.2. Own up to the problem, IT IS NOT HARDWARE AS YOU WELL KNOW.

8.1.1 does resolve my battery issue, however I suspect that after previous iOS 8 issues they are taking their time releasing 8.1.1.

My iphone 5s (64GB) drain fast. Turn off numerous settings I find on the internet wont help too.

So i sent to check at my mobile provider in which they said battery have no problem and send the same phone back. They also restore the iPhone and set it anew. But the battery drain still here. last night at 23.40 (battery is 74%) and in the morning at 6.21 (battery is 0% phone is dead) without usage (only in sleep mode). I am going to send the iPhone to apple again.

Good to know.  There's hope my issue will be resolved with the next release.

Got a new iPhone 5s as company phone two weeks ago and was perfectly fine with iOS7. 

Installed iOS 8.1 on it lately and now have random battery draining issues.

The battery just runs out completely within a couple of hours, without the phone being used at all and without apps running in background.

The phone feels quite warm, when this happens. Looks like some part of iOS8.x is locked up in an infinite loop and keeps burning CPU cycles.

I can stop this effect by shutting down and restarting the phone. I could not figure out yet, when and why the draining starts.

If Apple does not stop this before December 15, I will give back the iPhone.

Got my iphone 5s  replaced after i sent  to apple a second time. This solve my  the battery problem as i mention earlier. And now I restore my back up on to the phone and it still works great.

Apple what the hill is goin on we have problems with batteries so fix it it the major problem her.

i Can't even use my iPhone 5C the battery it drain so fast that I can't even reach 3 hours of normal use with no WIFI no 3G just with phone calls and few a text messages that it very bad and I'm upset apple.

FIX IIIIIIIIIT !!!!!

I have the same issue. Had a iPhone 5s...new in November.  Not sure when but in April time the phone started heating up and dying quickly.  So in October we got a new phone from apple after doing diagnostics returning nothing and me trying all the same stuff that everyone has tried.

Then we got the refurbished or whatever phone and it was perfect for a couple months. I think I updated the iOS ...not realizing it was going to send this new phone into this crazy state. I've turned my phone on airplane mode nothing installed it'll last maybe 8hrs on standby.  Usage is about 4 hrs at most.  So I'm hopefully getting a new phone non contract and hopefully selling this piece of crap on eBay.
