I know it's a bit early to say what the impact of 11.1 is on battery life, but this is a thread to report your experience as it becomes available. It's important to include 3 pieces of info:

1)What device and model this pertains to: iPhone, iPad etc. which model, generation and so on.

2)What you are making a comparison from: are you going from 11.0.3 or 10 or what.

3)What is your experience of the battery life from 11.1 compared to what you had before.

Battery life is a super important thing for most people, so this would be helpful in letting people know what they can expect.

Not too early. A lot of people were on Beta 5. I had about 7 and a half hours on the 8+ , now I'm getting about 8 and a half hours from 100% to 0. That's music with the screen on and doing stuff on the phone, FaceTime audio calls while doing things, snapchat videos, etc.
 
Iphone SE Verizon 16GB:

Battery hasn’t changed from 11.0-11.0.3, as in it is absolutely horrible and definitely has me looking for a Pixel. Usage hasn’t changed nor settings from iOS 10.3.3 and I only get 2.5 hours of usage before hitting 50% consistently (every single iOS 11 version, including 11.1).

10.3.3 I would have 4 hours of onscreenusage before hitting 50% consistently.


Been on this public beta 5, which is the same as today’s version so I have used it for a while.
 
iPhone 8 on Verizon 11.1- fabulous battery life! Coming from 11.0.2.

Usually disconnecting at 830am, school finishing at 630pm, battery is around 40-50%. Right now it’s at 76% with the same usage.

Standby at 10hr 10min.
Usage 2hr 11 min.
 
iPhone SE w/ 11.1. No improvement over 11.0. No new apps, enabled features, or usage diff vs 10. Used to end day with 40-60%, now <10%

Ever since 11.0 my iPad Mini 4's battery life has diminished and the percentage reading is inaccurate/inconsistent. It'll change by 15-20% in an instant. Today it died completely while saying 17%.

I'm pretty sure this is a software problem, but what's Apple's policy for battery diagnostics after Apple Care has expired? That is, how much does just the diagnostic cost?

IPhone SE user. No change in battery life since 11.0. Phone is still running warm as well.
 
I’m not sure it’s a “battery” problem. I think it’s a reporting problem.
On my 6s+, 10. Was good. 11.0, the battery % was all over the place. It could spend hours at 1% and not die.
11.1 seems better, but jury is still out.
 
6s there was no improvement on 11.1 still horrible, its about 20-30% worse than 10.3.3. My wifes SE has similar results, it used to have brilliant battery life, not anymore. I am due an upgrade soon and I am thinking about Android as I don't think Apple seem to know what there doing
 
iPhone SE, Verizon 16GB. I had been running beta 5 for a few days and then just went with that since it was the same as the official build. I had been on 11.0 through 11.0.3 and battery life was always horrible on those, and nothing had changed with 11.1.

Yesterday I restored my phone as new and only installed 2 apps: GroupMe and Planning Center Services (as I needed those ASAP). I noticed my battery was back to that of 10.3.3, as I used the phone constant (Safari, browsing, etc). I got the same, if not better, battery than 10.3.3 (4 hours of usage before hitting 50% battery). I then installed Modern Combat 5 and YouTube and set them up. The results were the same, battery was still good. I just recently re-installed my 11.1 backup today and will see if I still get good battery. If not, I will just have to restore as new and install apps one at a time to see which is the culprit.

Hope it helps

Battery life on my iPad mini 4 has been wonky on every version of iOS 11. It even died while reading 17% today.

My iPhone 8 Plus, on the other hand... see attached. Seems pretty good to me.
 
Yes I have noticed more rapid battery drain on the iPad Mini 4 and iPhone 6+ since going to iOS 11. I was hoping 11.1 would improve things but it hasn’t. This is a big deal that Apple must be aware of.
 
iPad Air 2, 11.1 is better than 11.0.3 which was better that 11.02/11.0.1/11.0/10.3.3.

8 Plus is slightly better than 11.0.3. But didn’t have any issues with battery on any version of iOS 11 on my 8Plus. I set it up as new when I got it.

I’ve had no issues with either device and iOS 11.x.x battery. Both devices were setup as new.
 
iPad Air 2 on 11.1 battery has been great. Averaging 13 hours with 5% remaining... 6S has been around 7 1/2 hours with 5%.
 
iPhone 6S. Waited for 11.0.1 and updated thereafter as each iteration came out (so now on 11.1). Battery life currently awful.

I take it off charge at about 7am each morning and, by lunchtime, with very light usage, it's down to <40%. I can no longer trust my phone to last the day. Without a top up it's in low power mode by the time I get home at 6pm, i.e. less than 12 hours. If I actually use it much at all, I need to charge it for the second half of the day.

I have no idea if this is actually bad battery performance or bad measuring of battery performance; i.e. I haven't risked letting it run down to see if it's actually running down or the meter is giving false low readings.

I was going to skip my usual two-year update cycle and get an Apple Watch (with LTE), but the performance of the 6S is so bad now - my wife has the same model and worse issues without updating - that I cannot consider this a viable plan. This happens every time a new phone comes out, so the two thoughts I have for this are that Apple deliberately hobbles old phones with new software to force us to upgrade, or that they make phones that barely last out the two-year purchase plan.

Either way, they are making it hard to stick with an iPhone, which means they're at risk of losing a customer for the phone and the watch at the same time.

11.1 seems to have improved battery things for an iPhone 7. Seems to have more juice again.
 
From what I am seeing iPhone 7 and above 11.1 seems to have improved battery, below the 7 battery life still dire. I can confirm this on my 6S, No matter what I have tried battery life has been awful.

Seems to me that phone has been standby/screen off most of the time... what about on screen time - actual usage time?

It's hard to say how much of the 14 hours of usage was screen-off. I would estimate that no more that 2-3 hours of it was simply playing music (mostly over Bluetooth). The highest energy users were Facebook and Chrome, but I don't have the numbers any more. All I can say is that I used the phone as I've always used my phones and it took over two days to drain.
