Mobile doesn't have 4K screens, any phone released in the last few years can handle 1080p or 1440p AV1
I mean ANY phone. My phone is $160 from 2019 and it can play 1440p AV1 on youtube (with a few frame drops, but nothing noticeable), even though it has a 720p screen. I'd have to get my OnePlus 3 (2016) to stutter in 1440p
note that the OnePlus 3 would stutter in h264 1440p as well, it's just old
It's not only about “handle”, it's about not eating through all of your battery before you're done watching the video. But no, “any” phone cannot reliably play 1080p AV1:
“Overall AV1 real-time playback of 720p 30fps @ 2Mbps is feasible for low-end devices with 4 threads and 1080p 30fps @ 4Mbps is feasible for high-end and mid-range devices with 4 threads using Dav1d decoder.”

we're talking about hours of playtime before you run out of power, you can verify this on your own phone on youtube right now, go enable av1 and marvel at how YOUR phone can play these videos at 1080p

Why only 4 threads? My phone from 2020 has 8 cores/8 threads and a 720p screen

Of which half of them are small cores (Cortex-A53), which is pretty likely to throw a spanner in the works of the threading model. But hey, feel free to inform the dav1d authors that their dav1d paper benchmarked dav1d wrong.
Maybe some difficult 1080p videos, but my phone can handle 30 FPS ones from what I've tested. It depends of course if you require NO dropped frames, or simply not noticeable performance degradation. I can't tell when it drops one frame out of a thousand
The Sony Xperia 1 series does (along with a headphone jack, microSD card support, notification LED, a hardware camera button, no hole in the screen for the front camera, etc.).
