I've recently installed elementary OS Juno on a laptop and it seems like the way it discharges (according to Elementary) is extremely inaccurate. I'll charge the laptop, unplug it, it'll go alright for a bit, then suddenly drop from something like 30-40% to 5% and try to shut down, however the battery is not empty.
I'll keep it running and it'll stay on 1% for hours, until it then finally fully shuts down due to lack of power, and it won't turn on unless I charge it.
It keeps doing it and I was wondering if there's a way to fix this. It seems like it's a calibration issue or something. I've check the bios and the battery health is still good.
