We can better assess your issue if you tell us the apps and activities for which you are using your computer.


Chrome is a known battery drainer on both Windows and Mac laptops. Installing useless after-market apps that claim to clean, disinfect, protect, optimize, or mop your Mac's floors will also accelerate battery drain.


Watching videos or video-conferencing are high-stress as well. I do both on wall power whenever possible.
