ios 8 battery drain issue and Bluetooth issues

I had the same problem with the battery so I contacted Apple support via chat. They had me upload diagnostic info to them and their recommendation was wipe the phone completely, restore the phone via iTunes and setup as a new phone. The tech's thought was downloading the update via Wifi caused some corruption of the iOS 8 update. This whole process took me about 4 hours between diagnosing with Apple and then wiping the phone, downloading the update, etc. It did clear the problem up completely though. I have everything re-enabled again and the battery issue went away. I also let the battery drain from 100% to 0% right after restoring the phone so it would get a chance to re-calibrate where fully charged and discharged were.

It was kind of a POA not being able to restore from backup but it wasn't that bad to set up everything again. My problem is completely resolved.

I tried all that ... TWICE ...it didn't work. If I have to pay to fix this ... I'm done with Apple.

There is an update available but why should I trust that it wouldn't be worse?

I permanently fixed the battery drainage problem by replacing the Apple apps with the Gmail app, Chrome app and Google Map app.

My battery usage is now better than it ever was before!

Google seems to know something that Apple doesn't.

yeah right lol

Hum... My #1 hog now is the phone App.

Waiting for a Google phone app for iPhone.

Did some research: apparently we can get a Google voice number and use it with Google Hangout and use data/wifi instead of LTE (much better energy usage). Anybody tried that?

Given that all my iPhone apps are now Google, and Apple does not acknowledge their problems, I will not order the iPhone6.

Apple managed to convince me otherwise. I will start looking at Google product specs now. They seem more efficient from this first time exposure.

Apple agreed to look at the phone at the Apple Store, out of warranty. I have to say that this is good customer service on their part, I'm happy about that. The out come will determine if the next phone I buy is Apple or Samsung, but they seemed to take my issue seriously. A step in the right direction!

What update? 8.03?

SOCORROOOOO !!!!!!!!!!

Minha bateria está durando no máximo 4 Horas!!! corrijam logo isso Apple!

i am having a battery drain issue as well with my iPhone 5 on ios 8.0.2. I have tried disabling everything including background app refresh, handoff and location sharing. Also tried resetting all settings several times and setting up as new device. I am only able to get 4-5 hrs of uptime on a charge. It used to be 6-7 before. Also my cell reception is definitely worse since the update.

My battery issue is when my phone has a week cellular signal it drains much quicker now then it did with iOS 7

i have the amae problem as well. iOS 8.1 doesnt seems to fix it. Done all the suggestion i found on the web but nothing stop the battery drain.

I have the same problem too! I contacted apple support and I restored my iphone 5s a bunch of times I want my stock 7.1.1 back I only had to charge it once a day and I tried all the fixes to make it work still nothing my battery just drains fast please apple fix this I can't keep charging my phone twice a day on just 4 hours of use! and I never had any problems sending messages on imessage please update apple.

If your battery is draining in three or four hours see if you are sync'ing contacts, email etc from Google within the standard Apple apps, under Settings-> Mail, Contacts, Calendars. When I disable this my battery life goes back to how it was in IOS7. What gets me is the arrogance of Apple in not letting people downgrade.

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.
