15% of battery…
My solution was to set BIOS defaults after this discharge of battery and again full charge.
I have more than 15% ….it’s 66% maximum.
Better than 15% but it isn’t 100% still.
Jumper company sent me information:
“The Battery is good, it is the BIOS and Battery did not good debugging.”
I asked what does it mean. They said:
“The way is very complexity”    “The problem can not solved by you” only return laptop to factory is the solution they mentioned….
In my opinion BIOS update maybe can fix this problem. But no update at present time.
