My best guess right now is something to do with Siri/machine learning/etc - notice how the iPhone 8, 8+, and X have no issues? Those phones have a dedicated processor for machine learning. Every other device still has all of those machine learning processes in the OS, but are still having to process it all - only on top of everything else through the standard processors.

Most posts I read express a drain with standard usage - as if, something extra is churning away with every use (i.e. learning usage patterns, and constant indexing new data as it appears - and perhaps consequent re-processing of it...).

I have zero drain in standby - more so with aeroplane mode. I get all of my weird drain after using the phone for any purpose - I could send a message and will be at 90% - unlock it 5-10 minutes later, and it's at 87-88% for no reason.

from what you describe (also in my case with a 6S+), it's seems like fake , or a inaccurate untrue drainage, that not really the exact value at the given moment..
i think it's a part of the problem because once i start charging the same "jumps" can go upwards..
so it's some calibrating stuff or update... not sure it's actually "real" drainage.

That is exactly my experience also. Standby has zero issues. It’s as soon as I go to do anything with the phone.

22% after 2 hours and 10 Minutes of use?

iPhone 6s 128 GB.

Are you serious Apple?

At first I didn’t think it did, but web-browsing seems to hit it much much worse now. Currently at 5 hours of usage and 13.5 hours of standby and I’m at 58%. Still great, but I feel like the SE had a bit more uuumph to the battery on iOS 10. I regret my upgrade for this new Control Center alone. If I had iTunes and a way to downgrade, I would. I can’t if I restore/erase my phone to default, can I? Which version would reinstall? Does it stay on 11? Ugh! Lol.

I usually web browse on my SE about 75% of the time, and on 10.3.3 I get barely 5 hours at 50% and 8.5-10 hours in all. I can get 5 hours on 60% if I do less instensive apps.
iOS 11 gave me 5 hours with 40%, and at the best 8.5 hours on a full charge. Still great, but I'm already paying in the speed department so I don't wanna lose battery, and I downgraded.
You shouldn't have to lose data, as you can usually just download the IPSW file and "update" via iTunes, but my and some others' experience was that it kills your phone and forces you to wipe it. I was forced to go back to 10.3.3 and restore from a week old backup from before I upgraded to 11. Do it at your own risk, I guess...
 
Iphone 7 plus. Clean install ios11 (ipsw restore via iTunes), no backup restored.

Battery when using phone goes down rather quickly on 11 vs 10.3. It's not atrocious...I still get somewhere around 9 hours usage time...pretty good actually.

Today however I'm using my phone the same way as before but via 2.4ghz wifi instead of normally always via 5ghz wifi. Battery usage today has been much less though...which is interesting. It was almost double that on 5ghz wifi. Going to test this some more...

Btw I do realise this can be a very specific situation in my case (wifi router for example) and therefore maybe not so very applicable for others. Still...

It just might have something to do with Siri.

I unplugged my phone (iP7) last night and restarted it. It drained 10% in 7 hours just sitting here. Battery usage shows 7 hours of use. Something is keeping it awake. I never use Siri, yet it showed Siri used 3% during that timeframe.
 
On the flip side, does it seem like it is taking longer to charge your device back up?
Never have timed it in the past, but both my 7+ and 12 Pro appear to take a good bit longer.
Might be perception ... o_O
 
tl;dr; iCloud Photos is using up battery in the background.

My 6S has only been on iOS 11 since Friday. I just had my battery replaced in my 6S yesterday. Today I decided to see how it did on a full charge without recharging at all (normally I charge on my commute and at work). To my surprise I was at 60% after 3 hours -- some light usage and mostly being on standby. Turns out Photos app has been using a ton of battery in the background (under battery usage says 2.2 hrs). After upgrading to iOS 11 I lost all my thumbnails, so I guess it must be rebuilding them? Also, last night I told it to resume uploading while on battery (it said it had paused to conserve battery) -- does that setting stay that way after you do it once? If so, how do you revert it back?

Also, with a new battery, does it take a while to calibrate before it accurately reports battery life?

I used a new SE on iOS 11 for the last week and had no battery issues. Impressed with the SE on iOS 11 in general.

In any case, I'll start worrying about battery life after iCloud Photos library is fully populated (just recently started using it on iOS 10, and it took a while for all the thumbnails to populate the first time).
 
I get about 6 hours out of my iPhone 7 before having to charge. Pathetic. They best patch this. Really disappointed in ios11 and I rarely ever whinge

Have you tried a hard reboot?

http://ipadinsight.com/ipad-tips-tricks/ipad-tips-how-to-hard-reboot-the-ipad-when-it-freezes-up/

Just wondering how many users complaining have tried that, and what settings they are using. Do you have auto-brightness on or off? And what about background app refresh?
Click to expand...

I have this in one of these iOS 11 threads.....
I was having freezes and app crashes. Worked with Apple, we tried a few things, eventually did a complete reset - set up as new and start over. This did fix the freeze / crash issue.

About one week later ...
  • Battery life is poor in comparison to use under 10.3.3 I have the same apps installed based on my previous setup and the same, as far as I can tell, settings excluding a few new/revised for iOS 11 - by lunch at 40%-50% vs 65%-75%
  • I have had to go back to "Charge whenever I can"
  • Charging feels like it takes longer - nothing data-centric, just impression
  • The freeze is back and apps crash too. Not as frequent as initially but ... :(
Can't go back - watch on OS4
Still - will trudge along and hope that the next update (soon?) will help.

Not the worst update (that was 7), but not the best either.
 
Updated my iP7 to iOS 11.01 two hours ago and rebooted, nothing running. Have not used it since. It’s showing 1:45 standby and 1:45 usage. Something is still keeping my iPhone 7 awake.

My iPP 10.5 is still fine.

Btw who thought it was a good idea to shrink the space bar and put the undo button there on the iPad :confused: it’s driving me insane as I keep pressing it undoing all my typing :mad:
 
My SE has been upgraded from 10.3.3 from 11.0.1, and I'm impressed. Performance is much better than iOS 11.0, much less stutter, and battery hasn't gone down 1% from 100% after using it for 20 minutes and having it on standby for 2 hrs after that. Seems good...:)
 
My phone was great all day (complained a few days ago), was around 30% when I went to bed. Plugged it in to the computer (my nightly routine), dead this morning when I woke up... I thought I was over the hump with this, guess not. I'm going to have to charge it in work now... WTF... I updated Friday and now its Wednesday, more than enough time for this. Brand new wire, my entire household has used it over the last few days with no issues, charged last night just fine.

I'm going to have to buy an iPhone X if this keeps up ;)
 
I am far from an expert on the internals of the phone but I remember a person instructing me what to look for and what to do. If there is an arrow to the left of the Bluetooth and battery percentage, then you have apps running the background you do not need to be on. They have to be switched to: only come one when in use. and make sure that you clear your apps every so often. Mine changed with the new up date (I think) because the arrow was there and I tried looking for the area to change it and then all of sudden it was gone.

Some other weird behaviour I have noticed:

Some system apps randomly using data for no good reason.

Calendar & Reminders - randomly uses data, have no Exchange account, or iCloud set up for it.
Contacts - same as above
Maps - never even open maps, but uses data occasionally
Settings - uses data every time it is opened

Will try toggling these off , and see how that goes - wasn't this bad on iOS10 though
 
I uploaded the battery logs (also from sysdiagnose) to the bug report. The first log created 4 files (17-27 MB total) and the second (sysdiagnose) 164 MB. It was tricky to create the latter since you have no indication it actually worked pressing the volume up+down + sleep/wake buttons (at least using an iPAD). I saw it did going to Settings > Privacy > Analytics > Analytics Data.

Yesterday the battery was down to 6% at 10:59 PM. I left charging the iPAD and today at 8:00 AM it was 100%. At 7:00 PM the battery was already down to 26%. I used during the day to watch videos and listen a few audios.

Does anyone else’s usage times seem messed up? Like it’s not counting the usage time properly? I’ve been using my phone with the screen on for 6 hours nonstop, but my usage time says 4 hours. Standby time is correct though
 
Youtube is massive drain right now, either uninstall or clear from background.
