iOS 15.2 Battery Drain

@crystal_star

Your screenshots are what my iPhone 13 Pro max and iPad Mini 6 drain looked like. I would lose 4-7% or so per hour, using it or not.

I turned off a bunch of Home Screen widgets, but Apple News made a big impact on helping return battery life. However, Apple News was draining battery and showing up as background activity on the "Settings > Battery" screen.

Nothing else was showing up as a big drain. When it was draining, I found that turning off other things did NOT help, like turn off background app refresh, turn off push mail, low power mode - none of that mattered.

Turning off Apple News widget didn't help to entirely stop the drain though, it just dropped it down to 3-4% drain per hour without using the iPhone or iPad. Something in the OS/system was sucking resources that didn't show up in the battery settings screen.

RESET NETWORK SETTINGS DID HELP, FOR A DAY OR TWO initially.

I tried to figure out why RESET NETWORK SETTINGS DIDN'T LAST LONGER than 1-2 days, and I traced it down to IN MY CASE my devices were being paired with my iMac and MacBook 16", and when I re-paired the devices to Mac it defaulted to "show my iPhone when connected over wifi".

Apparently I would always wait a day or two before connecting back to my computers, and after I did that was when the battery drain came back after resetting network settings.

Now that I don't have them set to show iPhone when connected with wifi, my reset network settings FIX has lasted me for over a week. I only have to plug my iPad in every 3-4 days depending on how much I use it. It has only drained 6% since 1:30AM when I had it at 100%, with about 6 minutes screen on and 43 minutes screen off usage.

Before bed at 2AM last night my iPhone was still at 64% after 16 hours off the charger with over 5 hours screen on and 3 hours screen off use.

I charged it last night, and am off the charger for 5 hours now, with 100 minutes of "screen on" use and I am at 88%. However, prior to doing the Reset Network Settings, my phone would have been down to 70-80% today without using it at all.

...So have the nongenuine battery replaced with a genuine one:

Same story. My SE 1st Gen (same configuration as 12mini) - no battery drain when not used (but huge battery consumption for plain music playing in background! - 11pm -1am).

My 12 mini ... no comments. Significant battery drain is the phone playing music or left unused.

Interesting part on the right. I charged the device using no-name Qi charger (9-12am). After that - no battery charge drop visible. Needs some more time for conclusions.

Yes, my phone is draining the battery very quickly and it is hot, when I am charging it after the 15.2 update.

After 15.2 update battery draining so fast and battery health percentage also dropped on my iPhone 12.

Yup I am losing my battery way faster than before.

I’m also experiencing a battery drain and warm up on both iPhones (6s and 8) and iPad Air 4th after updating to iOS 15.2

You would think before Apple issues a software update they would vent how it affects battery power. I wish I could go back to 15.1.

My phone is charging, but seems to be running down too quickly. I’m going to try CarPlay in a few minutes.
