    There is a glitch that is known, keeping background activity on even when Background App Refresh is all off. It’s not registering correctly.

    You should give it a day or two to settle.

    This is Low Power Mode. It can be enabled in Settings/Battery/Low Power

    Settle? You mean an update to fix the glitch?

    I understand usage is increased with a new system giving the false sense that battery life is worse. But today I have hardly used my phone at all. Plus it’s registering background activity with that setting off. It’s a known glitch (hopefully by Apple as well) and needs fixed

    Apps will run in the background, regardless of whether Background App Refresh is on or not. Background App Refresh helps apps run in the background more efficiently, using less resources. Apps need to run in the background so they work as you need them to. You probably have a few apps trying to adjust to iOS 11. Try swiping any suspects out of multitasking, then do a hard reset (reboot).

    After a major upgrade, as I understand it, Spotlight on iOS re-indexes all of the content on your phone in the background, using battery (and making the phone feel laggy.) In my experience, battery life and performance seems to settle down by the next day after I do a major update (or reinstall the device from scratch, or even from a backup.)

    It’s okay, not as good as 10.3.3 on my 7 Plus.

    I have this (probably wrong) sensation that is draining faster after iOS 11, like the battery % go down faster, but truth is that it still lasts me all day and more with normal or heavy usage. And the stand by/used time is about the same...so it’s just me I guess :-/

    Seem to have the usual battery life
    One thing I did notice that was draining a bit of life was that photos upload to iCloud via cellular was turned on by default. Before 11 I had it turned off and didn’t know it had turned it on until today.

    Definitely and issue in iOS 11 with battery.

    Unplugged 7 hours ago on 100%, light usage, and I'm on 54%.

    I can confidently say that with iOS 10, I'd be on at least 80-85% with the same usage.

    No settings have been changed at all.

    As others have said above it could just be the re-indexing that happens at each major update. If you restore your phone to any version (including back to 10) it will rebuild the indexes again.

    A week after updating? Nah, i'm not having that this re-indexing thing even exists.

    Updated, reloaded, restored, rolled back many-a iOS and other branded OS' in the past to know that this kinda thing is a load of tosh.

    My phone suddenly got better yesterday, and I had the final iOS 11 update from almost two weeks ago. Until yesterday, Safari was draining my battery more than any app. Suddenly, it's back down to iOS 10 battery use levels.

    For the record, my battery is lower than usual. Worse than it was with 11 GM on 7.
