Battery issues since update?

[FeliApple]

Coconut Battery doesn't read iPod Touch because it uses a different battery type, but aren't iOS updates solely at fault? My iPad 4 dropped two hours of usage when I updated it (and it was 5 months old only with like 50 cycles). On the other hand, I tested my iPod Touch 5G on iOS 6 with it being 3 years old on 2015 and it gave me similar battery time to when it was new - 6 hours, all screen on, web browsing with a few videos taken, no music - (no idea about health or cycles because, again, coconut cannot read iPods, but I'll do another battery rundown when I can now and state the result.
I think that as new updates add functionality that invariably drains more battery, no improvements to the battery are made (i.e, you don't install a larger battery, obviously.) So usage should drop, even if slightly.
Note: I could be absolutely wrong because I have no experience updating devices, but in the one case I did, that happened.

My 6s is coming up to two years old and battery life does seem worse since I updated to iOS 11.1.2. That's running in Low Power Mode all the time with most things disabled.

I chatted online to Apple Support and they did remote battery diagnostics. The advisor told me the results were in green and would be amber if the battery had significant wear.

Assuming the diagnostics are correct, it must be iOS that is causing the drain.

Didn't those diagnostics always showed up fine, except from extreme circumstances? I never did one but I read that some forum members whose batteries were in poor condition had them tested and they tested fine anyway even though their condition was everything but fine.
iOS 11 might cause the drain though, of course, as many people reported. I'm just curious about the accuracy of the diagnostics.

Hi there. I’m having similar issues regarding my battery life. Before IOS 11.1 (and even under the current last beta), and specially over iOS 10.3, i‘d get about 9 hours and even 10 of “on screen” usage. Now, with iOS 11.1, I barely get about 6.5 hours of onscreen usage. Before the update, i could use my phone for about 50 minutes before it drains from 100% to 99%. Now I only get 20 minutes with similar usage. I could easily use my phone for two days in a moderate way, without recharge.

Apple really needs to address these issues. How come to be posible this kind of unpractical behavior. More emojis in exchange of less battery life. No go for me.

Same here. InstallEd 11 on my iPhone 7 on Sunday.
I am at work all day and check my phone only during lunch. When I finished up 430 today and yesterday it's at 50% or less. Weird.

Update: I am still on 11.0.3 and still experiencing unusually high battery drain on my iPhone 7 (purchased 1 year ago) with light sporadic usage, and even on standby it drains fast.
When it displays 4% it shuts down right away.
I haven't done any of the resets or re-installs.

I don't have time to review this entire thread...anyone seeing Improvement in battery with 11.1.2 ?

My iPad Air2 is still on 10.3.3 and doing fine.

Thanks for any input!

Yeah, stay with me on 10.3.3 on the 7. It's the best.

Thanks. I will keep both iphone and air2 as is for now.

For whatever reason when I tried to install 11.0.3 on Air2 last month on same day as I did the phone , the install was not successful on the Air2 (whyIDK). glad now that at least my Air2 is still on 10.3.3...

You might not want to upgrade from iOS 10 if you are already on it and it's working fine for you and there's not much that you really need from iOS 11. However, if you are on iOS 11, you might as well go to the latest, in particular if you are seeing some issues.

I've posted this elsewhere but my entire family exhibits severe battery drain cutting between 2-4 hrs of usage across 1 6s, 2 6, 1 5s. I thought it was just me but when the wife started cursing and my kids when they never have before almost 2 days after upgrading to 11.x you know it's not the battery or device. I've been doing all sort of tests and I actually think they may have a driver issue with the wifi (when I had turned it off through settings, things got much better - havne't run enough test to confirm if it matches 10.3.3 though.

Definitely not just you!!

and not just wifi ---
I canceled my wifi service at home 9 months ago (many months before Install of 11) and I choose not to connect to the wifi at work, so unless I am at friend or family house It is rare that i connect to wifi on my phone. I have it turned off in settings and really only switch it on when I am staying at friend or family house for weekend, esp since the 11 update prevents you from REALLY turning off wifi thru the control panel...so to prevent the annoying pop ups I just keep wifi turned OFF off.

So the battery drain I am experiencing on my 7 is dramatic and Wifi is turned OFF thru settings.

I leave for work at 645 am with a fully charged battery. By lunchtime, just on standby in my desk, no usage, my phone is at 87%.
During my 30 min lunch break I MIGHT at most send or receive 2 texts, two emails, maybe surf 3 or 4 sites, make a phone call or two of 5 mins or less.
Aside from the light surfing most days I do none of the other during my 30 min lunch and am not able or allowed to use phone anytime except for during lunch.

no videos, YouTube or music. I don't watch Netflix on my phone. I don't listen to music or talk on phone during my 1 hr round trip commute.

When I get home at 530 pm phone is at 50% or less. A bit of light surfing And a 10 min phone call or two in the evening my battery is in the red.

Sorry, that was a bit of a cranky ramble! I look forward to this being remedied as I'm sure you and your family are too!

Before the update, i could use my phone for about 50 minutes before it drains from 100% to 99%. Now I only get 20 minutes with similar usage

Exactly my findings also. I now seem to average around 15-20 minutes before 99% hits and is downhill quickly after that. This seems to me quite a dramatic shift in behaviour that I can only pinpoint it originating with iOS11 install. Something is off.

Same here.

Plus, the battery drain more in standby mode as well. Yesterday after a phone call at midnight my phone was at 79% and this morning at 7 AM it was at 71%. On previous iOS, I would lost around 2-3% max over the night.

Yes I will keep the Air2 on 10, no issues there, so don't see need to update it.

For my phone I am happy with most of the 11 features so far, aside from the battery drain and having to go into settings to turn off wifi.
so you're right, prob no reason not to install the the latest 11, that I know of anyway.
Thanks for input.

I monitor my cpu usage using system status lite. It’s always around 20% with WiFi on. As soon as I turn it off, cpu usage drops to 4%.

What are these phones doing on WiFi?!

 

[kebrone]

I get 6 hours usage. 7+
It was double before I updated.

I know a lot of people are buying X model because of the battery on their old phones. I guess Apple succeeded with converting people from old to the new phone by reducing battery on the old models. I don't understand why we are accepting this. Is there nothing to do with this? I

Those people could be buying cheaper iPhone 8 or even 7 phones if the battery is somehow the main/only reason they are buying a new phone.

Why? THe battery hardware isn’t at fault. It’s iOS 11.

What are you supposed to be demonstrating here? You’ve only showed the bottom of your usage and, in any case, not all “usage” is equal.

So why are they buying more expensive iPhone X phones then? Let's at least pretend to keep things in the context that they appear in rather than just jumping in with something else.

That’s with moderate use as usual. 2.4 hours of Safari browsing and 1 hour of Apollo on Reddit.

Same usage with iOS 10 easily reaches 10 hours of usage and with extremely heavy use it lasted 7 hours on iOS 10. I know this because this has been my usage pattern for more than a year.

Because since iOS 11 is only optimised for the iPhone X and iPhone 8 to a certain extent there is no point getting a phone which will not run iOS 11 well. If you are going to upgrade, get a phone which is actually a upgrade. The 8 isn’t much of a upgrade over the 7 and hence people are buying iPhone X just like me.

 

[Feenician]

moderate use

It’s meaningless. You have no accurate measure of time and look at something like the the YouTube app which had massive issues with inefficiency. Your “moderate use” metric is meaningless.

People with 8 aren't really dealing with some sort of battery issues. iOS 11 is the iOS that came with it, so by your own take on how it all works, that's the iOS that would work best on those phones. Just because you want to make things more fitting to promote some iPhone X agenda once the earlier iPhone 8 agenda didn't quite work out and the promoted "facts" didn't hold up and had to be revised and deselected, doesn't make it all so simply based on twisting things to fit the narrative.
