iPad Pro M4 iPad Pro hot and draining battery while watching a YouTube livestream

I thought the M4 SoC had hardware AV1 decoding, and that it was way more efficient. However, I’m watching a livestream of something important is happening in a point of our mad world, and the iPad is very hot, very very hot at the place where the M4 is, and the battery is plummeting.

I know this YouTube livestream shouldn’t represent the overall efficiency of the M4, but even before this, I’ve noticed a shorter battery life compared to my M2 iPad Pro. After 6h, battery life fell from 100% to 21%. My M2 after just 6h would be at 40-45% left.

iPadOS 17.5.1

I will report back once I install v. 17.6

This is concerning. If the M4 somehow draws more power than M1 despite being newer generation, I’m worried about how I’d use it later on. I am a heavy iPad user and would prefer a decent battery life out of it.

Has anyone confirmed Google has even bothered to enable AV1 in the iOS app?

I haven't done what the OP did but I use my 13" M4 Pro a lot, including processing 4K videos (Lumafusion), processing lots of large RAW images, watching long movies, etc. and haven't run into it getting hot or being more battery-intensive than my M1 12.9.

The screenshot suggest you use Safari to watch, but just to be sure: you use it or the youtube app? Other than that: approx. A total of 8 hours AV1 playback (what screen brightness btw.? resolution of video?) does not seem to bad, doesn’t seem to bad. 🤓 But, yeah, that your M2 plays with ~50% better efficiency is strange.

Just to clarify, yeah, I use Safari to watch YouTube. Maybe that’s the reason? The brightness is always under 40% because I’m indoors.

Anyways, during other activities it’s pretty efficient so I’m not sure what to think about this. I’ll keep you updated.
