So I have an iPhone 6, currently running iOS 11.1 PB5.
Most of the posts I see and the people I know say they're getting great battery life on iOS 11, but for some reason I don't.
I turn off as many things as possible, background app refresh, mail push, and more. I did a clean install (11.0.3), didn't help.
I even replaced the battery.
If it's a software issue, why didn't the clean install fix it. If it's a hardware issue, I just installed a genuine battery.
It's been bad since iOS 10.
I even lose ~30% overnight, with airplane mode on, no open apps, and everything off!
Any help is appreciated.
*There are no Apple Stores in my country, so I can't check it there*

Been habbening since iOS 10, hope soemone who had and fixed this can help me.
This thread is for issues after updating to iOS 11.
Well, as far as suggestions or things to try and all of that thread has information of that nature. Now if the thinking is that it's more device related than iOS related (since it's not being associated with iOS 11) then it might be more of a hardware type of issue perhaps with the battery or the device itself and it might be worthwhile to contact Apple about that.

I think you may have a battery issue. My iPhone 6s will sit for six hours overnight on Airplane Mode and still be on 100%.

Sounds like you've tried everything else, so I'd lean towards the battery itself being the issue.

I installed a new genuine battery, didn't help.
There are no Apple stores in my country, how can I know what's causing this issue?
Oh, and I also bought a genuine cable and a wall plug, didn't help.

Had same issue where my phone would lose battery life for no reason, turned out to be a hardware issue and I had the phone replaced.
