Battery percentage inconsistencies

I am experiencing inconsistent behaviour of the battery state in Windows.
Here is what I have observed:
Rapid draining: The battery seemingly drains very fast when using Windows, however, upon rebooting and plugging in the charger, the battery level seemingly "jumps" to the correct percentage.
After disconnecting the charger, one of the two things will happen:
- The charge level gets stuck on the level it was at the moment the charger was disconnected
- The battery seemingly starts draining very quickly, as I have explained above.
Steps to reproduce:
- Use the tablet with windows. Observe that battery is draining quite quickly.
- Reboot the tablet, using Windows's start menu
- after rebooting and logging in, plug in the charger
- observe that the battery level jumps by a significant amount as soon as the charger is plugged in
- disconnect the charger
- observe that the battery level is either stuck, or starts draining quickly like before
Expected behaviour:
- The battery level stays consistent with the real battery level
Additional note:
I am quite sure that this is a bug in one of the battery drivers reporting the battery level incorrectly, as when I reboot to Android when Windows shows about 10% battery left, Android still reports more than 70%.
