Hello I feel that my iphone7 battery is being drained even with the gold master and the iphone heats moderately but very quickly with barely no usage. I mean, I answer some texts or browse across wifi and my battery drops about 8% in 20 minutes. I dont know if I'm Paranoic, but I had iOS 10 until last week and it was working great about battery left. I woke up at 6 am and had about 85% battery or 80% by 12pm, now i have 75-70% with very low usage because i dont use it too much at work.

Is there anyone with that feel?
Also, i have been searching for a mean duration of battery during normal use, day to day basis. A real number, not the duration that apple proposes because I feel that is only theorical values. I dont know if im paranoic about my percentage and that's why Id like to compare
 
I haven’t tried any betas but just installed the GM. I feel that my battery is draining faster too. I updated mine before going to bed, so all the indexing should have been done during the night while on the charger. I have a 6s.

Damn but it DRAINS a lot faster... I don't even have features like background refresh, just imagine what that would do. Also, since I updated over 1 day ago, I guess it already finished indexing. I don't know if I should go back to ios 10 because it really get's on my nerves.

I once read that only because of it being a BETA, it will consume more power, doesnt matter if it is GM or not, do you know about that?
 
First 24/48 hours will have different power profile for every new OS install, beta or not.

Let the phone rest, reset once at the end of the day and another after you wake up.

Let us know about battery life after 72h.

My iPad Pro 9.7 is having great battery life through most of the betas, including GM

The GM turns WiFi on by default (seems to always be on)
That may be part of the issue

what do you mean? I use wifi most of the time, that's supposed to lower the battery usage if you have a good stable connection vs cellular, which I do have in this case, that's why I use it.
 
When I turn the phone on, WiFi is on by default. I’m walking around the airport and don’t need WiFi, so I have to turn it off to get better battery . Going from airplane mode on to off, WiFi turns on also; wasn’t like that in iOS 10.
 
Oh yes, I have noticed that toggling airplane mode doesnt turn OFF all communicactions, only cellular. I have reported it as a bug but i dont really know it its normal behavior. However, I do use wifi, and when NOT using I manually turn it off.

hope u know wifi on but not connected or scanning is the same as having it forced off. the difference in power draw is hardly measureable by professional equipment, in english that means ud save a whopping... couple SECONDS on battery... stop believing myths about constantly needing to spam that wifi toggle off.

my 7 plus has normal fine battery same as ios 10.

That’s by design. So you can still connect to a plane’s Wi-Fi and your Bluetooth headphones without having to toggle those settings separately

Too much mis-information out there Most of the stuff on the internet just pass on the same old tired myths and never provide a source. I wish the tech sites did a better job educating their readers instead of just posting press releases.

Here’s an actual news article

Thanks that saved me a couple seconds of battery by posting a broken link. I was worried for a second there...

I haven't seen anything from anybody that claims battery savings of decades, but I have seen your post claiming that it only saves seconds.

He’s actually right. Leaving the WiFi button on doesn’t do much to save battery life. Toggling it on\off all the time does kill your battery more. Because your powering it up and not letting it just sleep in a not connected state.
 
Omg I thought I was the only one, updated my phone literally two hours ago when it was %100.... now %62 which is shocking because all I did is text after the update...

Not saying this is 100% the cause, but you could have 3rd part app(s) which have issues running properly on iOS 11. Wait until next week when updates start rolling out

I was having terrible batter life on iOS 11 GM. I found that Mail was running away with my battery life and making my phone hot. Disabled all Mail accounts (I use Outlook app anyway) and phone no longer hot, and if anything, my battery life has improved vs. iOS 10.
 
Excellent for me. In fact, I’m blown away by how good battery life has been.

Edit: 7+ 128GB here

Were your mail settings configured to push new mail? Instead of losing your desired functionality, you could (if you haven’t already) switch to fetch instead. That’s typically a common battery saving trick, but it could help with your heating too! Just thinking out loud.

What qualifies as 'all the time'?

Thanks for your suggestion. I’m 99% sure it was on manual for 2 email accounts, with push only for iCloud (not email).

To be honest, I’m barely losing anything as I was using Outlook app for all my email anyway.
 
I installed iOS GM on Tuesday my 7. My phone got relatively warm throughout the process of downloading the software (nothing that I haven't experienced with major iOS releases). Since everything has settled, my battery has been as good and even better than it was on iOS 10.3.3. Just my experience.
 
My battery life is shocking after the update to 11GM, it was bad when I did the ota from 10.3.3, but this morning I did an iTunes backup, did an ipsw restore to 11GM, and its still shocking.

I’m hoping it’s just indexing at the moment and will be better tomorrow.
