My 6s is a few months old and I have some battery issues. Basically it used to shut off at 5, 6%, no huge big deal, but this has blown out to 12, 13% now it shuts off as high as 35/40%. There's no consistency to it though, it can sometimes last right up to 1% although this is very rare. Occasionally I've managed to restart it and it's lasted another hour and the battery % even increases without charge i.e it shuts off at 30% I managed to get it back on and it climbs to 32%. I've updated to the latest IOS and restored to factory defaults numerous times with no luck. I've taken it into my local Apple approved repair centre (Macworx) and was able to demonstrate the battery issue, but they ran a number of tests including a battery health test which came back as all OK. So I've spoken to Apple who say take it into their store, which is miles away, but I'm guessing they are going to want me to demonstrate the problem, which I can't always do and I'm sure they'll just run the same tests as Macworx. It's still covered under it's 1 year manufacturers warranty. Has anyone else has this issue?

Same problem here. Battery indicator says about 30 %, suddenly it shuts down. Won't turn on and screen says I have to charge it. After waiting a couple of minutes, I can turn it on again. iOS is 9.3.2, clock is set to automatically update.

I had a similar problem with my 6, I had to make several visits at the Apple store (diagnostics showed nothing wrong) and try wiping and setting up as new only to have the problem return. As I was covered with Applecare+ I ended up getting a replacement phone out of it. May I ask when you both got your phone btw?

I got mine in November 2015

This is happening to many here. I would suggest not allowing you device to run low on power as when it turns off is unpredictable. Hope Apple fixes in a undate
I wouldn't call 30/40% low on power but anyway, the other issue is the battery life is abysmal so going from 100% to 30% takes no time at all. I have to ensure anything remotely power guzzling is turned off, like Bluetooth, but then half the phones functionality is gone.

Bluetooth is not a known "guzzler" of battery power. I would look at apps like Facebook.

I consider myself a moderate user and never have less than 40% of my battery left at the end of a heavy day.

Have you calibrated your battery?

What is the ambient temperature around where you guys are having your phones shut off on you? Is it normal room temp? Are you guys going from a warmer place to a cooler place?

I got mine (original) in November 2014, my replacement (end of April) seems to be much better - certainly the battery is much better even compared to the first one when it was new. I'm think in the rush to get new phones out maybe the first batches have some faults? My 4 and 5 were purchased 4-5 months after and had no such problems.

On the other hand my 6 had no problems the first year prior to ios 9, so I wodner if there is an underlying software issue at play here?? I've reported it anyway - hopefully Apple can figure out what is wrong.

My current phone usually ends the day with 50-60%, I agree bluetooth doesn't seem to drain my phone, Facebook on the other hand...horrible.

The main issue though isn't the battery life, it's the battery indicator which I think is probably a software issue? i.e reporting an incorrect reading. But then it will die at 30% and come up with the "plug it in to charge" symbol, however you can sometimes manage to power it back on for 5mins, then it goes off then you power it back on and it stays on for another hour. The other day I was trying to demonstrate the crap battery, it was on at 11%, turned the brightness way up, put on a video and 30 mins later it was still on 11%! WTF...

Just normal room temp most of the time.

So I took it to the Apple store and they very reluctantly replaced it after a good 20mins of arguing with the "genius" appointed to look after me. Unfortunately the new phone is doing exactly the same thing.... does anyone know if Apple do refunds? I do not want a 6s!

Hey, what is the status of your battery problem now? Apparently after iOS10 update many users were hit with exactly the same problem, me included:

I’m just curious to learn if you were able to fix it after all.
