Battery Drains in iOS 8.0.2 iPhone 5s

I have the same issue. Had a iPhone 5s...new in November. Not sure when but in April time the phone started hearing 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.

Thank you to all

Guess what, Apple called back and are replacing the phone after testing it. They admit is is faulty.

Something in the software update upset the hardware and they are replacing at no cost

Indeed there was a continuous power reboot which they saw in their tests

Best solution - replace the phone, which is still under guarantee.

Happy Appling everyone!

DE9.

sounds awesome. I actually was able to do that with the original phone and got a new refurbished phone wwhich worked great for a month or two. Warranty was 90 days and apparently I was 95 days in and the apple store said you're Sol and even said doesn't look like its my fault but looks to be another faulty phone. Yea the store is 2hrs away so it's a pain to get too. I had a coworker who also had the same problem and she tried everything but it kept dying. She just got rid of it which I hope to be doing soon unless Apple would do something about this...

I had a perfectly good iphone 5S until the last few updates. Called Apple yesterday, wiped out and rebuilt the phone from scratch per their directions (battery tested fine per them), and today after waking up and pressing one notification, it happened again. The phone went from 70% to 0% in one second. Plugged it in and within seconds said battery was nearly charged again. Yet I know it is unusable because it is so unpredictable. You never know when it is going to fail. I don't know why Apple doesn't at least own up to this issue and provide a fix. Can't buy the new 6/6S for several months yet personally. I wonder, do people with the newest version also have this problem with the software updates anyway?

Oh, and Apple Store/Supervisor was a real pain yesterday. First they wanted to charge me 29.00 to even speak to someone at the store about the potential security issue (so I thought due to it being a power problem). Then when I got someone who said I didn't need to pay for this issue to speak to anyone, after working with me for a while on the phone, his supervisor took the call, sent him on another, refused to turn her headset down so that we could carry on a decent conversation (echo was so bad we could not communicate), took my phone number, and then never called me back. I waited 45 minutes. No call. Then this morning found the darn phone and alleged fix did not resolve the issue.

Come on Apple. What the heck are you thinking?

iOS 8 also drains my iPhone 5s 32GB battery, that's why I upgraded to iOS 8.0.1 and then 8.0.2.

But then I found out both decisions turned to be a nightmare!

I need iOS 7.* back!

i have same problem bro, battery like sh1t, i am using iphone5 battery drain very fast from 100% to 20% its only 3 hours usage and 5 hours device stanby.. w7f i hate ios 8 😕

Yes, I am experiencing email issues, as well.

My 16gig at&t 5s is having same battery issues. phone feels warm and battery just disappears for no reason.

Downgraded to 8.0 and will see if there is a difference tomorrow

Downgraded to ios 8.0 and still having the same issue. Hope they fix this soon

Same issue here. iPhone 5s. Drains from 100% TO 10% in an hour!!!!! This makes the phone unusable. Gonna try the downgrade back to 8.0 to see if that helps.

I am having the same issue with my 4S. Soon after updating to iOS 8 the battery wont even charge. It drains fast even when connected to charger. This is a serious mess by Apple.

My Iphone 5S after upgrade to 8.0.1, the finger print unlock function not working,

then upgrade to 8.0.2, the battery life draining crazy.

Now my iphone becomes useless.

As an experiment today, i put my phone on airplane mode while working and appeared to have no excessive battery drain.

So many people with the same problem, and apple seems to ignore it... and support denies it!
