I compared the speed of the cellular network to two applications - a native application from Qobuz and USB player. I tested one quality track 24-192. How the native application works:

At first there is a surge in speed, and then the speed rhythmically jumps, but the recording is not interrupted:

USB player for some reason behaves differently:

Changing the buffer size, network packet size, client type does not change the result. Why is this happening? The official application is able to maintain a constant speed of downloading music, and with a USB player, communication is constantly interrupted.
We suggest excluding the app from battery optimisation. Of course the app streams data in chunks.
