Hi @ranaground,
See if you have TLP installed, or something like that, to optimize battery power life.
community/tlp 1.4.0-6 [已安装]
Linux Advanced Power Management
Do I need to delete it?
Can it be optimized?
With THAT I’ll not be able to help you. I don’t have a laptop and neither do I have any blue teeth. Or green for that matter.
I only mentioned it as something you might look into. You’ll have to look closer.
Maybe this’ll help: Power Management - Manjaro
Disable ‘TLP’
Can solve
