M300 Shutting Itself Off Whilst Playing Music
Hello! I bought an M300 last September. I've never had this issue until this week, where it has shut down multiple times whilst listening to music, often after about at least 30 minutes of listening. No issues with the battery, as the device has been at a good battery level each time.
I have a 2TB sd card where I store all my music, 858gb currently being used, no music is stored on the device itself. 99% flac files. File structure is simple, just SD Card/Music/ then all the songs in seperate artist folders. System is up to date, I'm using PowerAmp and Niagra launcher, I don't do any streaming, theres nothing else on there apart from Hiby Player, Brave browser and the system apps. I play with aeroplane mode on to save battery, I listen on bluetooh Shokz Dots or hooked up via aux to one of those brick tabletop Soundcore speakers (the issue has happened with both).
It's getting really irritating now and I'd rather not buy a new one, so any help would be appreciated! Massive thanks in advance!
