Battery drain since iOS 15.6 is ridiculous

Same problem on all our Apple products. Did an upgrade on two IPhone 12, one IPhone 11 Pro, and one Iapd Pro 11“ 2 Gen.

All devices updated form 15.5 to 15.6. On each device the battery is running super fast empty. not usable anymore without a powerbank. O; each devices!!

A clean install on one of the IPhone 12, and then a backup from ICloud also didn‘t fix the problem. Apple said this should fix it, but it doesn‘t. Even ‚‚twas getting worst, after update battery health crashes from 100% health to 94% and one day later to 93%. this come is 6 month old!

So big warning, don’t install IOS 15.6.

Apple, please fix this problem, and don’t let us make extra route with fresh installations. It won’t work!

BR.

As everyone posting in this thread is just complaining, and no one is willing to consider troubleshooting their problem, I’m giving up.

My last advice:

• Apple doesn’t read ASC looking for issues; this is a user to user forum, so saying that “Apple must do something” is as effective as shouting it into the Grand Canyon.
• If you want to passively let Apple know, use this link→Product Feedback - Apple. They will record your issue, but won’t respond.
• If you want to actively let Apple know and get help from Apple, click on Get Support at the top of this page.

Apple has big time messed up with everyone’s Phones with iOS 15.6 update. IPhone 12 Pro Max with iOS 15.5 battery used to last 2 days. No other changes except iOS update to 15.6 and battery doesn’t even last half day.

This squarely is an Apple iOS issue period.

That is a totally different issue, and has nothing to do with the subject of this thread.

How long has it been since the phone was new? The drop in maximum capacity is not always linear, but on average it will be about 1% a month for the average user. So if the phone is 3 months old or more that is a reasonable drop.

Batteries are consumables; they lose a little capacity every time they are discharged, then recharged. On average this works out to about a 1% loss for every 25 “full charge cycles”. As one example, if you charge the phone overnight, every night (and that is what you should do; it is a best practice), it starts the day at 100%. If it drops to 20% by the end of the day before you charge it again overnight that counts as 0.8 full charge cycles (20% to 100%), or about 24 full charge cycles per month of use. For this example your battery capacity will lose about 1% per month. Of course, if the end-of-day level is higher than 20% the capacity loss will be a little less, and if it is lower than 20%, or you charge it during the day, the capacity loss will be higher.

Once the capacity drops below 80%, or if there is a message in Battery Health that the battery is not meeting peak performance expectations, it’s time to change the battery→iPhone Battery Replacement - Official Apple Support

The absolute best way to get maximum use on a charge, as well as slow the decline of battery capacity long term is to enable Optimized Battery Charging (Settings/Battery/Battery Health) and charge the device overnight, every night. The battery will fast charge to 80%, then pause. During the nighttime pause the phone will use mains power instead of battery power, allowing the battery to “rest”, and thus reducing the need to charge the battery quite as often. The phone will resume charging to reach 100% when you are ready to use your phone; it will “learn” your usage pattern. If you enable iCloud Backup (Settings/[your name]/iCloud - iCloud Backup) the phone will back up overnight also, assuring that you can never lose more than the current day’s updates.

How long have you had your iPhone 13? In normal use maximum capacity will drop about 1% a month, so if you have had it for more than 4 months 96% is about right, or if much more than 4 months, better than expected.

FIX THIS PLEASE, or I’ll switch to a different phone.

No one participating in this thread can "FIX" anything on your phone and threatening to buy a different brand of phone won't change that.

If you're having problems with your phone, I suggest you contact Apple directly:

Does it still have its original battery?

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

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

they don't see these posts guys please report on feedback on feedback site otherwise they do nothing

16.0 resolved the battery drain on my iPhone XS Max. I’m procrastinating downloading 16.0.3.

Same problem with my iPhone 13 Pro. Just updated to iOS 15.6 yesterday from iOS 15.5. I don't run a lot of apps ... read two newspapers, talk, text, and take a few pictures. From a full charge, phone drained to 20% in a couple of hours of nearly none use. iPhone 13 Pro got so hot in my pocket that I had to take it out and shut it off. This is not the first time I have had Apple battery issues after an iOS upgrade.

Same here. Upgraded my brand new iPad Air from 15.3 to 15.5 then to 15.6. Battery is draining like a timer. My Xs Max even worse now coming from 14.8 with 96% battery health. I even lost another 2% battery health after upgrading to 15.6. Waited two months for this and look at it.. Hope Apple resolve this.

My battery life has improved greatly after updating to 15.6. After following the best practice of charging overnight, every night with optimized charging enabled, before updating I would be at 20-30% by the end of the day. Now it’s around 50%. So rather than just complaining go to Settings/Battery and check what is using all that energy. Battery energy doesn’t just evaporate; SOMETHING is using it, and that something is always an app or apps.
