Battery issues since update?

[SoYoung]

This morning I let my battery die to recalibrate it. I dont know if its normal but maybe 2 mins before it dies the phone lagged a lot like if there's not enough juice to perform well and when I plugged my phone (when it was died) it takes like 20 min to turn it on again and it shouldwed 7% battery life but it decrease to 3% 2 mins after.

I think my battery % is messed up...

I'll add my story for iOS 11 and iPhone 8 battery issues, it seems worse in inexplicably the battery drains very quickly for a short period of time, independent of any heavy use. It could be a rogue app, or an app that acts rogue due to an iOS 11 bug or feature maybe? Or another idea, as I saw this last night --

I have a Mophie Qi charging pad on my desk, and I happened to be working last night. So when I went to bed, the iPhone 8 was 100% charged (as its is most nights). Now, at night I always sit my phone next to my bed, with Do Not Disturb on, NOT being charged/plugged in. I have been doing this for several months, and I never saw the battery less than 98% doing this; in fact, roughly 50% of the time I would say it is still at 100% in the morning, the other 50% of the time it will be at 99%. This has proved true even with the iPhone 8 which I have had since the first delivery day.

So this morning, I pick up my phone, and it is 78%. Wow. The night before it was 93%, two nights ago it was also in the 70s. Last night there were no phone calls, text messages, there were some notifications that came in for news etc. but nothing out of the ordinary, and being in DND mode (which I verified), the display doesn't light up. So I look under the battery setting to see if anything odd happened - I see Wall Street Journal, which I subscribe to, "1 minute background", 33% of total charge in last 24 hours. I happened to remember I brought it up very briefly once yesterday. I don't know if that would have shown before I went to bed...

I have never had any trouble with that app before, and the other nights it was not the culprit, in fact nothing obvious was. So I don't see any obvious app problem causing the fast drains.

One last part to the puzzle - this morning, at my desk I place the 78% charged phone on the Qi charger, and in 30 minutes it is at 100%! Doesn't that seem fast for a non-fast-charge charge? So now in my theories I am adding that maybe the iOS 11 bug is that the phones are not properly reporting their charge level?

I am thinking the reporting of the battery is the issue - see my post right above!

You're just wasting your battery life cycles by doing those recalibrations. There are no support documents from Apple that suggest to do recalibrations.

I've had really bad battery drain in iOS11. Currently on 11.0.1 because I don't have enough free space for 0.3. While 0.1 is better than 11 the main issue I am experiencing is a sudden 20% drop on the indicator when in standby and when the screen is on the percentage doesn't count down for quite a while and when it starts it drops fast.

Draining alot, warming alot.. good way to destroy pir batteries and a month later we need to get a new phone or replace the battery... my phone feels warm almost all the time, sometimes hot. If that aint foing to break the battery, then nothing...

12hours later today, lost about 90% during the day - with ios10 i didnt even charge it daily.

Yup I didnt realise they were doing planned obsolescence with the batteries before I had to replace mine on my 6. That's when it hit me, how clever their scheme is. They get money either way.

Can you guys that still have these problems post a picture from the apps that are draining the battery the most? In the last 24 hours AND 7 days. That way we can tell if it's caused by any specific app (or not).

My IPP 9.7 (128 GB wifi only):

Battery is down to 57%. Been using for watch videos today. Health of the device: 8% degradation:

And how many of you tried a clean install? *

* This is what I did:

*****************
Ok, after a clean install (as described here http://wccftech.com/clean-install-ios-11-final/ ) and setting up as new (without restoring from a backup), my battery usage improved by about 90 minutes - 2 hours. It’s still somewhat worse than what I had on iOS 10, but definitely a noticeable improvement.
*****************

*****************
Trying this now to see if things change... with iTunes 12.6.3.6:

https://drive.google.com/open?id=0B5ZTWFGLynGWa2psWmsyeE1lSkE

Release date: September 22, 2017; 16 days ago
- Adds iOS 11 support.
- Released to enterprise customers for deploying App Store apps to iOS devices.

I'll do the same and don't restore settings from iCloud, will start from scratch and reconfigure my preferences for all apps. Let's see if things will improve. Of course I'll download everything I had again.

Note: I had to follow these instructions to select the IPSW file:
http://www.redmondpie.com/how-to-clean-install-ios-11-via-itunes-the-right-way/

Which included holding Shift (in PC) to select it from my hard drive, instead of downloading from Apple's servers.

So this is me after downgrading to 10.3.3 on my 6s. As you can see at the end of the day and I've 50% battery left. There were days on iOS 11 where it never made it to the end of the day.

That's rather impressive. I've never seen usage/standby numbers of that type with so much battery left on a few iPhone 7 devices I deal with using any version of iOS 10 (or 11).

All depends what you do on the phone I guess. My screen time is low as I listen to podcasts etc most off the day and just let it play away on my phone.

 

[lookatchu]

Battery drain is ridiculous on my 7 plus. It seems to go down 20% just by breathing on it. It also seems to run hotter.

I guess it's a good thing I'm getting the X. I'm sure Apple is ensuring that the battery time works better on the iPhone X or else they'll get a beating in the press.

 

[SoYoung]

I refuse to buy a new phone because the battery sucks. I bought my 6s plus a year and a half ago and I expected to have it for at least 3 years. Buying new phone every year encourage big corporations to do planned obsolescence.

iOS 9 destroyed my battery. This is a fact.

The iPhone X will get trash battery life next year when iPhone X Plus launches.

And that anecdotal supposition doesn't change what I pointed out.

If only it was so easy... I dont have any special app using the battery. If that was a case, i wouldnt complain here but rather uninstalling that app immediately.

battery life on iOs 11 on my 7 Plus is rather bad too, cant figure out a way to solve it, im gonna do a fresh install when i get my iPhone X next week as opposed to restoring from a local back up.

 

[The-Real-Deal82]

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!!

 

[Radon87000]

Absolutely atrocious and horrible battery life on iOS 11.1 Beta 5 on 7 Plus. Only 6 hours. Very very bad. How many releases are Apple going to take to fix this

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!

You all need to keep sending battery logs for this link:
https://developer.apple.com/bug-reporting/

Click on VIEW BUG REPORTER and enter your Apple ID (login/password). Then post a short text saying the battery is awful. They will ask for 2 logs to be created, sending specific links to you.

I recommend (in the short text description of the bug) posting a link to this thread from Macrumors.

 

[BA2020]

iOS 11 sucks. (Buggy and seems to make my battery worse)

Not worth it on my iPhone. And sucks batteries (or maybe it’s just how it appears, but why would Apple want to make it look worse?)

On my iPad iOS 11 is definitely worth the upgrade, but iPad battery also seems to suck worse.

Processing power of an iPhone 6 is constant. Apple doesn't optimize code for the iPhone 6. Leading to laggy software. The end

That's more along the lines of basic technological progress in play, which is somewhat different than the purported planned obsolescence and all that carries it with it.

Apple priority development:

iPhone X >> iPhone 8 >> iPhone 7 >> iPhone 6s >> iPhone 6>> ......

iPhone X, 8 = iOS 11.1
iPhone 7, 6s = iOS 11.2
iPhone 6,... = iOS 11.3
