Battery drain and heat - iOS

I am having the same issue on a brand new iPad Air 11

Was only able to watch about two hours of a show and it completely drained my battery from 80% to 10% in about two hours.

Is this being worked with Plex support?

Plex Version : 2025.14.0 (1037)
iOS: 18.14.1
iPad Air 11 512gb WiFi only

I just set up Jellyfin Server in 30 minutes on the same host server as Plex, with Swiftfin IOS on my iPad. I watched the same exactly 4K movie hosted off the same hardware from start to finish on my iPad, without any heat or glitching, and it used a total of 3% battery on the iPad.

The Plex team should be ashamed they forcibly pushed this product to market. There’s no way they didn’t know it wasn’t ready. I am exactly the customer that this company built their business upon, and I am exactly the customer they are alienating with their current decisions and behavior. What a travesty.

Same issue here. I ran into this problem in earlier betas of the preview app, but I was always able to switch back to the tried and true Plex app to avoid it. Recently, I’ve been streaming with the Infuse iOS app, but I decided to give the latest Plex for iOS app another shot — and the problem is still there. I woke up to find my phone burning hot again, so I immediately switched back to Infuse. The issue doesn’t happen there, and honestly, I’m tired of roasting the literal life out of my phone and battery.

In this particular case, the app was just direct playing low bitrate h.264 content.

Again.. this or similar h.264 content has never done this to my phone while direct playing with the previous app or while using the current Infuse for iOS app.

Been watching a 4k movie in version 2025.15.0 (1045), still in beta, for over 30 minutes and have only lost ~3% battery and my phone is cool to the touch.

This is promising.

Severe battery drain on iPad and iPhone with all versions of the new plex app experience. Thus most recent data captured from an iPad Pro (11-inch) (4th generation) running iPadOS 18.4.1 (22E252).

Note for one hour of playback plex used 79% of the battery.

so you are running at least 2025.15.0 (1045) of the app? can you share the app logs?

Just experienced this today on the new app. I was on iOS 18.3.x at the time, only updated to 18.4.1 afterwards. 30 minutes of x264 1080p video took 20% of the battery on a 5th Gen Air and left it very toasty. Hadn’t been a problem before the new app installed; streamed same video yesterday on old app without issue.

Possible to get your app logs?

Yes, how do I share them? I’ve managed to DL and they go back far enough to cover the relevant time frame.

click on my username/avatar and there is a message button so you can send them directly to me

@jabithew your logs indicate you are on version 2025.14 . Can you see if app store shows you can update the 2025.15 version

Yes, that worked. Update was available and video issues have gone now, thanks :+1:

I have version 2025.15.0 on my iPad Pro 3rd gen, just updated it. I wasn’t aware of the issue and watched a 20min video (1080p)…when I went to remove the iPad from the apple keyboard folio, I almost couldn’t handle how hot it was.

I’ve seen apple devices overheat, even with my own code, but this was so hot that I’m scared it could damage the device.

Between this and the bug with keyboards, you should do a ā€œrollbackā€.

This is a huge problem, it’s almost unusable. I have to leave my iPad Pro plugged in constantly now, where before I could go days without charging. I’d very much like an option to turn off what has basically rendered plex on my iPad useless.

I also am running latest version of app 2025.15.0 (1045) with latest version of IOS for iPad. Devices gets extremely hot watching movie/show hosted on Plex Media Server. This never was an issue before until the latest update.

Mine literally gets so hot that the iPad stops charging because of overheat. Even with my iPad plugged into a charger, Plex STILL drains my battery to zero. How is it even possible to write an app that bad? This is a HUGE problem… I can’t believe there has been zero addressing of this. It’s literally unusable…

Same issue here. Ipad Air M3 and even when watching DVR’s SD content, my ipad gets uncomfortably hot. I’m confused as to why this is happening when it didn’t happen before the release of the new app. Direct play, no transcoding happening.

Having the same issue on my M4 pro 11ā€. Watched 10 minutes of hdr 4k and my device is extremely warm. Never had an issue before I’m on 2025.15.0

Same here on a M4 iPad Pro and 2025.15.0

I agree. The update looks great, but it hasn’t been good. There is also a massive battery drain and heat issue. The old app i wouldn’t have to charge while traveling for work and now I’m less than 50% on the first leg of my trip watching one video. Watching that video, the iPad was warm to the touch.
