My table is working like a charm.
At home I leave it 24/7 connected to the charger.
Battery always show that it is 100% charged.
When I turn it off and later on again, battery is 100% charged.
Now when I do the same after having avast battery saver installed,
it always shows as 99% charged when I turn the tablet on.
It also takes about 1 hour before it reaches 100% again.
Where is that 1% going when I have the tablet off and connected to the charger ?
