So i’m guessing streaming lossless audio all day has a bigger effect on your battery vs non lossless? I‘ve been seeing an unusual amount of battery drain on my phone lately And it seems it may have to do with this.
In theory lossless should be LESS of a strain on battery since the decoder has to do less work. In reality, this is almost impossible to test for without jailbreak tools.
There will be an extra strain on the battery as you’re constantly downloading from the server. More data streaming means your iPhone spends more time constantly online instead of going into idle.
