I recently got my XPS 15 and was messing around with the BIOS settings for battery life. I changed from the Adaptive mode to Custom charging, from around 80% to 90% thresholds. When I booted up my machine, the battery indicator on the taskbar shows "plugged in, charging", but that clearly is not the case, as the battery life gradually decreases as if it is not charging at all. Also, it no longer shows the estimated remaining time, but "Calculating...". I tried reverting back to the Adaptive mode, but it still has the same problem. I also installed the Dell Power Manager program to see if that helped things, but it hasn't.
Has anyone else had this problem after changing the battery settings in BIOS, and how can I fix this?
