Battery drain since iOS 15.6 is ridiculous

It doesn’t make sense. I just got my iPhone 11 and the battery is draining like crazy. If even new phones are doing it then I would definitely bet on it being the update for a lot of people

If you just got your phone, it's most likely still doing some background updates and indexing. You'll need to wait several days before you can get an accurate idea of battery life.

Not so sure you are right here Lawrence. My Wife's Iphone 6s plus has gone from usable to unusable with this update.

I've checked every setting, looked at battery usage that shows the battery going from a night charge 100% to close to 5% in under 2 hours, yet the phone doesn't show any obvious candidate for the drain, safari was the highest on 'battery usage by app' but it had barely been used - this was a period of minimal usage.

Same result after many days of overnight charge (and optimised battery charging is enabled, always has been).

According to the phone's presentation of the data it is 'like' it has evaporated - though I know it's impossible, just something is draining it, but ios 15.6 is not recording or showing what it is.

Never seen anything like it

rwps ~ With an older model such as the 6s Plus, an obvious candidate for the drain is a weak, aging battery...

Does the iPhone 6s Plus still have its original battery?

And what's the Maximum Capacity % here?...

Settings > Battery > Battery Health

the bit that seems to be missing here is that the phone has consistently worked well lasting all day with regular use, only minor degradation of its battery life that was not impacting or being noticed.

Building in obsolesnce via an update seems to be excused by some as acceptable. Our world can't afford so much waste.

Same here on a iPhone 11 Pro. Is there hope this will resolve with newer updates or is the battery damage permanent…?

2 iPads (one brand new generation 9) pretty much having the same issues. I watch the battery drain before my eyes with light usage 😬🙄

I am having a similar problem with excess battery drainage on two iPhone 12 pro maxes, an iPad Pro, and an iPad Pro second generation. I am using AT&T in St. Louis, Missouri. My problem started after installing iOS 15.6.1 and updating my apps. I am getting as much as 3.5 GB per day of "Settings > Cellular> System Services> Push Notifications", and my (otherwise healthy) battery requires unusually frequent recharging. I turned off all app Notifications (except Phone and Messages), and all background app refresh. Also, at Apple Support's suggestion, in Privacy>Location Services>System Services, I turned off several location related System Services (such as Location Based Alerts). This has not worked to stop the Push Notification data hemorrhage. Phone calls to Apple Support on 8/21/22 and 8/22/22 also failed to solve the problem. So far, the only way to stop the Push Notifications is to turn off Cellular Data, which defeats the main purpose of having a mobile smart phone. Even after stopping Cellular Data, I have noticed unusually rapid battery depletion if Wi-Fi is turned on. Please check your Push Notifications. If that is your problem, perhaps Apple Support will be able to help you.

Ye u noticed it too. I only bought my ip13 lat feb .and 100 % til this june. July 98% and aftr updating it to 15.6 it drains too fast Frm 98 to 94! For just a month ! It drops for about 5-6 days aprt! Really wnted to cry! Idont know if ill be updating to ios 15.6.1 cos it doenst fix the issue.. and i read and wtch that ios 16 also has batt issue. Maybe my batt will end up 70 or les by sept .. wat shoud i do!! Im thinkng not to use it until apple fix ths issue

The thing that impressed me most about my iPhone was the battery life. IOS 15.6 has destroyed that perk. Battery now completely drains several times each day, and charging takes forever, even with my quick charge device. FIX THIS PLEASE, or I’ll switch to a different phone. Google Pixel is looking better and better.

IOS 15.5 and 15.6 totally ruined my experience. Moving from 14.8 couple of months ago, I’ve now lost 7% battery health and have to charge my phone twice a day. I’m seriously consider moving to Sony pro series.

hank ~ What model of iPhone is it?...

Does it still have its original battery?

And what's the Maximum Capacity % here?...

Xs Max, purchased in Jan 2020, brand new. I hardly use my phone, original factory battery, I mainly use my ipad. I was on 14.8 for a long time and my battery lasted at almost twice longer than what it is now. Battery health was 98% on 14.8. Then upgraded to 15.5 when released losing 2% health. I had horrible battery drain on 15.5 then upgraded to 15.6 and losing further 3% battery health with it. Now battery health is at 93% and my daily usage hasn’t changed. I have lost 5% battery health between two IOS releases. Seriously, something is wrong here. Yes, my battery may degrade over time but I hardly even use it and my phone looks still as pristine condition following best charging practices as I can. I truly regret upgrading to ios 15. Worst experience for me ever.

hank ~ To have lost only 7% caoacity since Jan 2020 is unexpectedly good — a decline of 1% each month or two being typical. At that rate it should have declined by at least 16% (1% every two months during 32 months.)

Thanks IdrisSeabright. I will disable that feature.

It's actually a great feature that will, in the long run, increase the overall life of your battery. I'd recommend considering using it. See the article above on when to charge your battery.

Like the majority of us his phone was fine until that dreaded update. Mine was. It’s just another unfortunate apple bug that comes with each update. Even after the new update they still haven’t fixed it. Sucks.

IWhat if had optimized battery on before the update and it was always fine? Does that update affect that part of the phon? Nine of the updates did before. It’s a new bug in my eyes. Still not fixed either and I rarely use anything and stuff is always off. So low battery mode redux.
