Battery drain and heat - iOS

Can anyone please share their iOS logs from while this is happening so I can add to additional report.

I’m stumped. I’m trying to duplicate the problem and I’m not able to. It seems to come and go for me.

A couple nights ago I was in bed with my iPhone 11 Pro plugged in and charging and watching an episode of Columbo in bed with my Wyze Ear Buds Pro connected and the phone got very hot.

After seeing this post, I plugged my phone into a charger and put on the same episode and I’m listening / watching it right now and the phone is NOT getting hot.

I’ll keep trying to make it happen again and upload logs.

The beta 1053 build of 2025.15.0 seems to have resolved it. I haven’t had the issue for some time now with that build.

It’s not fixed. I’m on 1053 on TestFlight and I’m still getting the heat problem. When it happens I force quit the app and open it again and it doesn’t hear up for a while. But this is unacceptable.

Hi, I’ve also experienced the issue on my ipad. I’ve attached the logs

I may be hard closing more often then. I would agree it shouldn’t happen regardless.

Here are my logs:

Any updates? Yesterday I tried downloading an episode into my ipad (thinking that maybe the issue was in the streaming), but no, even playing the local file it started to get really hot.

Sorry I do not

Crazy. Not a priority I take it.

It’s not something we’ve been able to reproduce internally.

There was an issue in earlier builds that I was seeing myself but that was resolved 2 or 3 patches ago and since then even my old 7th gen iPad no longer has any issues with heat or battery drain during playback anymore.

It may be specific conditions causing it which is why folks are asking for logs.

It happens on both my iPad Pro and my husbands iPad Air. It happens 100% of the time, the Plex app is 100% unusable to me, it gets so hot that the iPad refuses to charge, and drains the battery in about an hour. I sent my logs. If this doesn’t get fixed I’m going to have to move to Jellyfin… I don’t really have a choice. Or you could rerelease the old version of the app for people having this problem.

Thanks, did you post the logs somewhere else (I don’t see them posted in this one)? If you can point me to them I’ll poke somebody on the player team to see if they can spot anything in there.

Log file upload. Finally had the issue happen again last night.

I was watching episodes of Barney Milller on my iPhone 11 Pro running iOS 18.5 and Plex Client version 2025.16.0 (1068)

Server version: 1.41.6.9685

I had the phone plugged in to a wired charger and one of my bluetooth Wyze Ear Buds Pro in my ear. I fell asleep and woke up a little while later after at least 2 or 3 episodes autoplayed. I felt the phone and it was hot to the touch through the Otterbox case it was in.

If you need more info than that, let me know.

I’m surprised you haven’t been able to reproduce as it happens a lot, here is a log from it happening with a downloaded file.

This file played from my downloads seems to heat it up. I had this set to high or medium quality, not original, though it’s an M4 iPad so it should handle h265 or whatever the original file was if it has flipped back

Thanks folks! I’ve poked at @Craig_Holliday about this, hopefully something in the logs can help.

Based on some of the logs shared I have a few ideas of fixes.
If anyone is able to share a sample file that will help me narrow down the issues but either way I’ll be taking a look

Here’s an example of something I was watching yesterday and triggered the issue: https://drive.google.com/file/d/1QtpLj6JlSjV5ULlZeAKNUuzLmcVLeET5/view?usp=sharing

Btw, if it is related to the files, I don’t know if you are aware (or even if it was fixed already), but, at least on the iPad, the streaming kind of stops in the middle of an episode if the file has an empty stream; I don’t know why the files I get sometimes have an empty stream, but it took me forever to debug it, and now I have to run ffmpeg to remove empty streams before moving the files to plex.

Something doesn’t look right, but just one thing to keep in mind. You have selected a specific 1 hour period, where during that 1 hour Plex used 79% of the battery usage at this time.

Not 79% of the whole battery. During this hour your battery reduced from 80% to approx. 44% (36% decrease).

Not suggesting that Plex should be using this much just to be clear.
