iPhone heats up when playing sound

[schumannd]

:beetle: Description

When playing sounds, the phone heats up significantly. very noticeable after +10 minutes of continued sound playback. this also happens when the app is in background, so it shouldn't be the playback update callback, right?

:beetle: What is the observed behavior?

phone gets 🔥

:beetle: What is the expected behavior?

phone should stay ❄️

:bulb: Does the problem have a test case?

Play a sound for +10 minutes (make it 20 to be safe) and check the temp of the phone.

:bulb: Is there a workaround?

ice? only releasing in scandinavia? Its probably nothing critical, but still an indicator of unnecessary battery/cpu usage.

:bulb: If the bug is confirmed, would you be willing to create a pull request?

It seems like big players such as spotify and apple seem to have had this problem as well. Maybe a pointer into the right direction would help? Id love to dive into the native side of the player.

This was due to us using the playback update function to frequently (updating an animation every 200ms causes the phone to heat up)
