Why did the battery drain very quickly after installing Linux?

Question

linux

after endless attempts, I decided to go back to windows 10, but now it has the same problem, the battery indicator flies away quickly, and the remaining time constantly shows 13 minutes. What could be the problem, battery wear? It's just that everything was ok before the installation, but as Kubuntu was installed, problems immediately began.

Answer 1

Why is my battery draining after installing Linux?

It also discharges on Windows - __-
Or maybe something was damaged somewhere in the laptop and the change of the Axis is just a coincidence. Maybe overheating, left the laptop on charge overnight, etc.

Answer 2

And why not assume that the battery is dead? Hand it over under warranty, since it is 5 months old - let them sort it out there.

Answer 3

linux may not work correctly with the hardware in the laptop, because of this, the laptop may sit down faster. try a different distribution from a different company.

Answer 4

Drivers, energy saving utilities.

Answer 5

Look at the battery wear, in the same AIDA.
The battery can be "finished" in 1 day))
I think the issue here is not in the OS, try resetting the BIOS, maybe they changed some mode, for example, to a productive one, although it is unlikely, since the spread is at times.
