I have a DELL LATITUDE E7450 with battery issues. When it is fully charged (displaying 100%), after some time the battery charge drops suddenly from 100% to 0%. When I unplug the charger, it warns me that the computer will shut down, and it indeed shutdowns after a few minutes as if the battery was completely empty.
When I replug the charger with the battery at 0% charge after the bug, the whole system is much slower (meaning that it takes a lot of time to even load a web page or do other stuff), and I have to hard reboot to have the system back to normal.
Finally what I came across is that if I remove the battery (while it’s at 0%) and put it back, the display will be correct, and if I unplug and replug the charger after that there are no problems on the system.
The bug is usually happening if I let my computer plugged for a night. So I guess after several hours of charge, the bug happens.
I’m running on Ubuntu 18.04.3 LTS, and in the BIOS the state of my battery is Excellent.

And this is the output of
