    I updated to iOS 11.1 thinking it’ll be better than 11. It’s worse!

    I'm not sure if this is the same for everyone but on my iPhone 7 I see a little cloud symbol next to only apps that I presume are 32bit. When I click on those apps to download them, it says the developer needs to update the app before it can be installed - see pics below:

    I have no battery issues with my 6 month old SE. Works like a charm.

    Isn’t that for apps you haven’t used in a while which could be offloaded to save space?

    I'd be interested in your set up, but that's more work than it's worth.

    On iOS 10: Settings> General> About> Applications. This will show you a list of apps that are currently incompatible with iOS 11, 32-bit or otherwise.

    Right. With background app refresh and all location services off the battery is at 70%. Yesterday it was 48% so an improvement. Tomorrow I'll turn on background app refresh to rule that one out.

    In my experience, location services and background app refresh are the two settings that can annihilate the battery. It pays to pick through the settings and turn off any you don't need or use.

    Just turn it off.

    No I don’t think that’s it. I have OFFLOAD UNUSED APPS disabled and the message I got specifically mentions the app needs updating from developer to work with this version of iOS (2nd pic in my previous post).

    the SE does seem to have avoided the battery issue. mine is working great. so, seems specific to the SE's battery...

    Most battery tests have proven that iOS 11.1 performs better than 11.0.1. That’s why I installed it. The last beta I installed was iOS 10 Public beta 5 on my iPhone 6s. Absolutely killed my battery. Never wanted to do it again.

    I have no idea why siri is using so much battery:


    Stat is 15% over last 7 days.

    I have an SE, that’s why I was asking.

    So far seeing similar reduction in battery life on my iPhone 7 as well. There is a day here or there where it's closer to what it was like with iOS 10, but for the most part there's a reduction of about 20-25% in terms of average daily battery life (both usage and standby).

    Hopefully an upcoming update will help out with that sooner than later, assuming there's something somewhere that could be addressed to either fix and/or optimize something.

    Definitely feel the same as you do. I dont you if you become paranoic with batter % but I feel that my iphone heats up pretty quick, and it wastes a lot of battery on stupid processes such as sending 2-3 messages, or browsing something pretty quick. I get a lot of standby hours, but as soon I use it for 10-20 minutes it drops about 3-4%. I am almost sure that in ios 10 i got at least 85% on iphone7 from 6am to 12pm normally, now I have about 75% and by 4pm i have 50% with barely no usage

    I'm going too take this back. Battery life is definitely worse compared with iOS 10.3.3

    Public beta testers get paid nothing. You get what you Apple pays for.

    I didn’t have much of a battery drain FWIW with the later betas, only the GM. 11.1 has been pretty stellar on my 7+. I did do a restore and restore from iTunes backup back on 11.0 if it’s any consolation which didn’t help with the battery. 11.1b1 has definitely helped (though it still occasionally warms up a bit randomly on the right upper back corner).

    3 devices on iOS 11.0.2, an iPhone 7 Plus, iPad Pro 10.5,and iPad mini 4. All are suffering battery drain, for every 4 minute of standby time, I have 2-3 min of usage time. That’s with the devices resting and not being used. Something is wrong.

    What the hell is going on with this? I have a BRAND NEW iPhone 7 and after I installed iOS 11 battery life has been draining rapidly. I lose about 20% the 8 hours I am sleeping as well. Even put the phone in low power mode and that doesn’t really help which is surprising.

    Something is going on in the background of these devices. Last night I drained the battery of my 7+, hoping to calibrate the battery and hoping that would help. Nothing has changed this morning. Unplugged at 7AM EST. Down to 94% at 9:16 EST, having barely used the phone. My new iPad Pro 10.5, drains battery all day while not in use. No clue what is going on, but there must be some process working in the background that has to be stopped.
