Battery issues since update?

[I7guy]

I’ve got to say the battery life is dreadful on my iPhone 6S since updating to iOS 11. Up until a couple of weeks ago I was going an entire day and ending it on about 35-40%. Now I’m looking to charge my phone by the end of the afternoon. I’ve been through turning background app refresh off etc and it’s made little difference.

I don’t want to do a fresh install because I want to keep all my old photos and texts on my phone and to be honest I shouldn’t have to compromise on things like that. I have updated to the latest version and it seems this battery life issue still hasn’t been addressed?! As I write this post my battery is super low and I’ve hardly used my phone today. Not happy and hope Apple are on it!!

I am on b5 and my battery life seems to be what I’m used to. B5 has better power mgmt it seems than previous iOS 11 releases.

i WISH i was able to get 6 hours on 10.3.3, my iphone 6 is very very old and i only get about 2-3 hours every day until i get the 20% message, when i'm lucky i get 4 hours out of my phone!

Check battery health in Coconut Battery. I have an iPhone 6 which was having battery issues like you but the battery health had deteriorated to 70%. I got it replaced and now its susbtantially better although not as good as on iOS 8.

Is B5 what we are to expect from the next update?

I normally record my phone’s battery life. I always restore my iPhones and set them up as new when updating the software, so there’s no corrupt app or setting draining the battery. My 7 Plus’s battery health is at 98%. That’s from Coconut Battery, so it’s accurate.

On iOS 10.3.1, this is what I used to get. Battery health was at 99% with 80 odd charge cycles.

This is iOS 11.0.2. Restored and set up as new. Same usage patterns. Battery health at 98% with 140 charge cycles.

Again, both are clean installs over iTunes and set up as new. So there’s nothing corrupted that’s draining the battery. It’s purely down to the OS’s optimizations. Same settings. Same usage patterns. Same battery health.

It’s pretty clear that iOS 11 drains the battery faster. Now, since my phone has been set up as new, it doesn’t drain the battery overnight, or drop 10% in 20 minutes. That happens when somethings corrupted. That can be fixed by doing a restore. But what I’m seeing on iOS 11 is as good as it gets. It’ll be 1-2 hours less than iOS 10.

B5 is probably close to 11.1 gm.

I get just over 5hours using my 6S+ on 11.0.3, I used to get 9-10 hours of usage. I really hope Apple fixes this..

Restore it and set it up as new. You will get 7-8 hours guaranteed.

This is flawed and unscientific, I shouldn't doubt, but anyway:

That's dramatic.

Maybe Apple just changed how usage time is calculated. Look at your first pic, 12 hrs of listening to music but iOS says you used your phone for 8hrs. Wtf

The 12 hours would be from the last 24 hours, while the 8 hours would be from the last full charge (which was a little over 13 hours ago based on the standby time). Different time periods are involved.

More horrible battery life.

Yeah, like C DM said, that’s during the last 24 hours. The 8 hours of usage shown is purely on screen time. Maybe it counts a few background push notification checks. I know because during a period of 8 hours of sleep, the usage time goes up by around 30 mins. Let’s reduce 30 mins from the usage time. Still a lot better than iOS 11.

HAHA - you sir should apply for the marketing department of Apple!

Did you have apple do it or you did it yourself?

What do you want to do? Do you want to just sit there and complain about how the bad the battery life is, or do something to make iOS 11 work as intended? The choice is yours.

Believe me, I acknowledge the bad battery life. It’s not as good as iOS 10. BUT, it’s only down by 1-2 hours. It hasn’t been reduced in half. It doesn’t drain overnight. Doesn’t drop 20% in half an hour. If you’re experiencing that, there’s something corrupted on your phone. You gotta get rid of that to get iOS 11 working as intended, and the best way to do it is by restoring and setting it up as new. That way, you have a “clean slate”.

Try it. It works.

I got it done by Apple.

You are kidding, right? 1-2 hours less isn't a big deal? It wouldn't if over the years the battery was as good as it was in the past.

10 hours is nothing. The only improvement these devices had was less weight and faster charging with the 29W adapter... and that's it.

Anyone that claims the battery of these Apple devices is good should be punched to death. That's not funny.

And as you can see here Samsung also has the same issues:

I did a clean install on my 7 Plus and battery life is still half.

Did you restore your backup?

 

[itsmilo]

More horrible battery life.

this looks good to me lol 4,5 h of usage and still only at 44%. my iPhone 7 Plus only lasts a total of about 6 hours

 

[joeblow7777]

Perhaps more frustrating than the overall diminished battery life for me is the fact that the battery percentage has become wildly inconsistent for me on my iPad Mini 4, and remains so as of 11.0.3.

I’ll turn in my iPad with say 60% power, use it for a bit, put it down still saying 60 or maybe 59, wake it up 10 minutes later and it says 48%.
Then I plug it in and the second I connect the cable it says 55. I really hope 11.1 fixes this.

 

[raulsbd79]

Any improvement on battery on the iphone 7 on the 11.1 betas anyone?

 

[LA_LEE]

Nope, none on my iphone 7. The battery life was cut in half and the beta did not increase that at all.

So shady of Apple and I am sick of people defending a corporation who has screwed over tens of thousands of their customers.
