How much data does Apple Music use for lossless audio quality?

Apple Music’s Hi-Res Lossless audio consumes up to 2.9GB per hour, significantly exceeding the 120MB required for standard High Quality streams. Users can manage data consumption by configuring separate settings for cellular and Wi-Fi playback. Because Bluetooth connections cannot transmit lossless audio, high-resolution streaming requires wired hardware or an external DAC for full fidelity.
