Battery issues since update?

[Prof.]

My iPhone is always at 100% at the start of my class, by the end of class it's normally around 93-ish %. But since iOS 11, my iPhone was at 71% when my two classes were done.

7 plus here and same thing with battery draining fast. Also I can’t find the setting to turn off email fetching. I’m sure that it can’t help when it’s constantly downloading new emails even when locked.

Mine dropped like a rock today. Which is funny because I've been through the entire beta and it was never this bad. I have no doubts it'll work itself out though. And really it only needs to last two more days. 😛

Yesterday immediately after the iOS update, the phone was a little laggy and battery dropped to 40% by end of day (normally it hits about 80% by end of day). Figured it was busy indexing, etc... I also turned Siri back on and had way too much fun downloading all the voices.

Today? Battery life seems pretty normal. Absolutely loving iOS 11 - the new font, battery icon, I am a huge fan of the new menus.

Every time there is an iOS update, there are a ton of people complaining about battery life. Give it a few days. If you're anything like me, a new iOS update means I use my phone 3 times more than I normally do resulting in a lot less perceived battery life from normal usage.

Am I the only one that has noticed an improvement then? My iPhone 7 was at around 75% by 3pm, it's usually half of that if I'm lucky

Thanks to both of you. Got it set correctly now. I’m sure that will help battery life considerably.

I haven’t seen my particular battery issue posted yet and its the worst of the bunch 🙂

Installed os11 in my pro12.9 1st gen yesterday, good to go.
Today with it at 100% charge I completely powered it down, went to work.
2hrs later I tried to turn it on, 0% charge notification came up.
Plugged in to wall, instant power up showing 100% battery charge.

Now any time I unplug it, 20seconds after unplug she goes black screen. Hitting power button brings up no charge prompt.

No issues on iPad Pro 10.5, air 2 or iPhone 6. Pro currently at 79% with 3hr 36min use and over 14hr standby.

What device?

iPad Pro 10.5 and SE both running through battery much quicker than usual.

My iPad usually lasts a few days between charges, but today it went through 80%. SE suggested Low Power Mode unusually early in the day.

I’m hoping this is just indexing as another poster said.

6s and dropping very fast after every charge, never was this bad however the main background activity seems to be photos, so wondering if it will stabilise after photos has done it's thing. Whatever that is. Cannot access the app store but that is another issue.

It should get back to normal depending how much Fotos got to be indexed etc.

My SE 16gb with not much data on it works great for the moment. Only first day after update was a bit battery draining.

Under 10.3.3 I always had Fetch set to 1hr with no problems. Kept the same on 11 then Mail seems to be using battery. Back to 10.3.3 no problems. Think I will wait till a couple of updates before updating again.

Se is buring up like crazy just browsing safari. Holding off on updating 7plus

I'm seeing somewhat higher battery use after upgrading too (Did a set up as new, then restored from backup). End of day used to be 50% remaining on my 6S, and now it's closer to 20%

I did notice that - prior to upgrading - all my email accounts were set to Manual but after installing iOS 11, they all were set to Fetch / Push. I corrected that this morning and I am hoping that's going to bring things back in line.

Battery life is horrible on my 5s. It’s a replacement unit from exactly a year ago. I’m lucky if I can get three hours off a single full charge. LPM gives me five hours of use... though my 5s becomes so damn slow with it on.

Wait a day and it will be fine. First day of new update your phone is still doing all kinds of stuff on the background which drains your battery.

 

[Ashin]

I jinxed mine. 5S, no problems at all, feels really smooth actually compared to beta.

I checked my battery life earlier. Was 19%, which isn’t that great compared to iOS 10 by that time of the day, but soon after I get the 10% warning, what?

I enabled percentage (usually have it disabled), and notice my battery just kept dropping in chunks - fell to 7% with a minute or usage or so, then 5%, then turned itself off. All in the space of around 5 minutes.

So, iOS11 either has major battery issues, or I just need to do a DFU restore and set it up again. This was an upgrade, so it could have just broken upgrading

Mine was horrid yesterday, seems to be back to normal today.

This is normal for a few days after a major OS update. The phone is doing useful behind the scenes optimizations. After a few days, battery life will be back to normal.

My battery life seems to have improved since I installed the update. Things I noticed:

1) Podcasts was using a ridiculous amount of battery (over 50%) despite not listening to many. Dunno what this was, but things have calmed down;
2) Photos was doing a LOT of indexing of faces across devices. Don't know what the impacts of this were, precisely, but that indexing seems to have concluded.

My iPad Mini 4 is draining quick. Seems to be YouTube and Firefox Background Refresh. So turned BR off for almost everything. We’ll see.

My 6S was dreadful for about 18hours after upgrading. Mostly it was plugged in during this time but when I unplugged it and took a few photos it went from 100% to 29% in just 1.5 hours. I then plugged it back in and again it went from 58% to 5% in another 1.5 hours. Utterly shocking. I could pretty much just watch the percentage dropping as I looked at the phone.

During that time, the phone was extremely sluggish. Apps were taking a LONG time to react when opening. Doing anything was taking ages.

Then, things seemed to calm down a bit. Clearly some indexing / analysing operation had completed and the battery drain was reduced and the phone became more responsive.

However, today, I have still had to plug my phone in around 6 times during the day because it keeps getting close to running out of juice. Having looked at the battery analysis info, it had basically gone from 100% to 1% (with being plugged in several times) with only 1.5 hours of active on screen usage.

In my opinion, this is utterly unacceptable and I'm on to apple support about it.

I’m up to over 10hrs with 44% left and 29 hrs standby on iPad Pro 10.5. No issues here.
