Battery "drain" on ios 15.0.1

[sbailey4]

no, I didn't try to hard reset the phone, but I did a soft reset, which should potentially restart all the processes. Hard reset is a real pain, it takes a long time to set up everything back as I lime. Also all the MFA devices will be lost, which is a separate issue.

I checked the Analytic Data, and there is a lot of logs. Not sure which should be checked though.

A hard restart as mentioned refers to a process whereby you force reboot the device. Typically not needed as a regular reboot accomplishes the same thing. Some folks just think it does more. Its really meant for times when a device is locked up and you cant reboot normally (like pulling the plug on a computer). Below is more info. See the last of the document and follow that link for the "hard reset" process. As for your issue most times iCloud syncing, indexing, mail hanging, etc causes drain especially after an update. I would close all apps (swipe up partial way and when open apps appear slide them away one by one) and reboot afterwards and see if that helps.

How many of these problems are the OS re-indexing and/or optimizing the storage after a full system installation? It seems to me any time there is a major OS update on a phone or laptop these days there is very high SSD/HDD activity for a day or two and consequent poor battery life until things calm down. (Localization problems excepted; that seems to be pretty well verified in this thread!)

Yes, I've tried all that. None of the apps seem to be "running away" with battery life as per the Battery screen in settings, which I've basically been staring at regularly for the last few weeks.

Anyways, the last two days, the battery life seems to have settled down somewhat. Yesterday I was averaging about 4-5% drop per hour, again without doing too much on the phone. The active use is fine and as expected, it's the stand-by battery drain that I'm unhappy with. I just checked, and turned off (two days ago) the "Send Last Location" under "Find My iPhone". I am literally afraid to turn it back on for now, because the battery life has been more or less as expected over the last two days. I also did try toggling the whole Find My iPhone feature on and off.

Anyways, came back from the Apple store a few hours ago. I knew going in that it was a complete waste of time, but whatever, it's only about 10 min from me. The Genius ran diagnostic on my phone, and shocker, there's nothing wrong with it. His suggestions were: turn off background app refresh, turn on dark mode all the time -- umm, but, but, but shouldn't the ***** phone work right without that? Also these have always been on.
He also kind of commented that iOS15.1 should be out relatively soon. And then we discussed what dumpster fire iOS15 has been.

Try to power off the phone overnight !

When i updated to 14.5 the phone became very hot, and burned some ic in the phone (prob the TriStar) and used like 25%/night of battery when powered off.

The phone is junk now, needs a new motherboard !

It's an easy check ...

What? How is it "easy to check"?

Check % battery when you power the phone off (power button and slide) when you go to bed.
Then check % battery when you power it on again in the morning

If the phone is ok it should barely consume anything, like 2% in 24h with a battery of 90% health

A new phone should consume like 0% in 24h ...

Worth a check if you got probs !

I decided to do a full restore a couple days ago and last night I had no battery drain (sleep focus on). I use a smart plug to shut off charging at 85% and it finished charging at midnight. When I checked the phone at 7am it still had 85% so hopefully it will stay like that at least until Apple drops 15.1 and messes it up again!

FYI: During all this, I tried beta1 or 2 of 15.1, and at the time it did not resolve my battery problems.
But again, I think my problems have largely "settled down" -- going to keep an eye on it again for this afternoon to see what's what.

 

[k.alexander]

And after being seemingly ok yesterday, today, with me having done nothing different at all, the battery is just draining like crazy; 30% in 3 hours with minimal use. I killed all the apps, restarted the phone, and it's still draining, bc the phone is actually warm for prolonged period of time, like it's doing something -- what is it doing? I dunno! I'm going to throw 15.1beta3 on there because obviously 15.0 is pure garbage.

 

[Kentoch Mervel]

Same is happening to me. Yesterday went to work at 9 with 100% battery. Left my phone in a drawer, took it back at midday with 55% battery. I didn't even touched it. In battery menu, Find My was working in the background all the time. Today I removed my AirTag from Find My and my battery is perfect. I guess I'll wait for 15.1 to pair again my AirTag. Unfortunate.

Definitely a bit faster - and Im not one to cry wolf. Then I force rebooted the phone and today its back to champ level battery life.

I have big problems with Home app and enormous battery background drain. iOS 15.01 on iPhone 13 Pro Max.

 

[qassaa]

I signed up macrumors just to highlight my issue of battery drain. 13 pro max.
On iOS15, my battery drain overnight was usually 0-1%. After upgrading to iOS15.0.1, battery drain overnight is 4-5% which is unacceptable. No app usage is reported in battery graph and the battery just mysteriously drains as if someone was using it.

 

[macblokepro]

same situation here. battery drain has never been fixed since 14.7 onwards.

As someone else mentioned a hard reset is fairly simple - on your phone, I also have 13 Pro Max, it’s push volume up button then volume down then press in and hold the side button in until the screen goes completely black and the Apple logo appears. Not a pain at all unless you’re doing something else that is not a hard restart. This shuts down any process that may be running, even sometimes with a regular shutdown and restart.

There will be a battery drain after any iOS update until everything settles in for a day or so. I always wait till one day after an installation and then restart the device. But I’ve seen no abnormal battery issues on iOS 15 or 15.0.1. But I have seen something get stuck in the past on a previous device draining the battery, never figured out what it was but the hard restart took care of it.

I would be careful doing a hard reset. There seems to be a bug in iOS 15.0.1 where the battery percentage will get stuck after doing a hard reset. I would suggest doing a normal shutdown and manually power on the phone.

Don’t reboot/restart your iPhone 13 pro max, I REPEAT don’t reboot it

Me and @Boardiesboi had the same issue, restarted our devices, then battery percentage became stuck, wouldn’t go down, only way to get it to show correctly, was by restarting the phone every time, only restoring the device fixed the issue. 🤦‍♂️ DON’T!!!!!! restart your phone.

From what’s stated in that first post he just rebooted his phone not a hard reboot. I’ve rebooted my 13 Pro Max several times since activating it. I reboot all my devices weekly on a regular basis. I also did a hard reboot on the 13 because I thought there was an issue, there wasn’t but there has been no such battery percentage issue as noted by many in that thread.

It seems to be not a consistent issue. Just something I wanted others to be aware.

I mentioned higher battery drain after iOS 15 upgrade on iPhone 12. Now I’m on iPhone 13 Pro on iOS 15.1.1 and battery drain still seems higher.
I know that I can reset to factory defaults, but I don‘t want to because of my long history.
