Battery drain since iOS 15.5

me too, i m also facing the same issue.

Same here :(

Is there a way to uninstall the update?

There are a bunch of posts about this in the developer forum..even for 13 models. How do we get help? How do we uninstall?

In general, you do not get help for a beta - it's because o f the NDA you agreed to. However, we can post the link to the Apple article:

How to uninstall iOS or iPadOS beta software - Apple Support

Yep, this is how it works

They won’t. From the looks of it. This is the new model of business. experienced the same thing as you and believe that this is 100% on me because I decided to update, updates is how they get you.

It’s not faulty, it’s your mistake for updating the phone from iOS 15.0.. In a nutshell you got got like everyone else who updated

Is there a way to have the battery replaced?

yes there is, but you have to buy a new one, and it is not granted that it will solve the draining.

Good for you. I´ve been waiting since 20th July 2022, still running bad on battery.

My battery is draining like 2% every 10min since updating to ios 15.5 three weeks ago. My battery health is 98% percent. My new ipad air also behaving the same. No draining over night, solid performance but soon as start using it, starts to count down, fast. Hope to see ios 15.5.1 with fixes.

Both my iPhone 8 and iPhone 12 were updated to IOS 15.5 2 days ago. Both are now experiencing very fast battery drain. The IPhone 8 use to last me all day, now only a few hours if I don’t use it for phone calls etc. Apple did this to me when I had my iPhone 5. I did the updates back then. The battery basically died, I wiped the iPhone and reinstalled everything but it was never good enough to last even 9 hours at work and ultimately forced me to buy a new phone. Now I’ll have to replace my iPhone 8.

Has Apple abandoned us so they could sell a few more iPhones?

I found two possible options somewhere else to try:

• If you have a PiHole setup: Disable „Limit IP Adress Tracking“ in the Settings of your Wifi (if it‘s disable: activate and deactivate)
• Sign out from your Apple ID, restart and sign in again (you need to re-add your cards and keys to Apple Wallet)

I applied both, battery is now (9.30pm) at 33%. Before it was about 20%-point less.

There is still some issue I guess, but at least it helped a bit (me, maybe not you :/).

Good luck.
