Hi all

I have got a friends Samsung tablet, which does not charge - I tried another
charger, and it still - slowly goes to 80%, that is it after some 4 hours.
The charger is not the problem, so - a wild guess is the battery itself.

It is 1-2 years old.

Does anyone know anything about this?

Sonnich-

That is young for a battery failure, but is possible. If you search,
you should find independent repair centers that can replace it.

Another possibility is that the tablet's battery monitor circuit is out
of calibration. You may be able to re-calibrate it by completely
discharging the tablet to the point where it shuts down. Then recharge
it overnight using its supplied charger.

Use the supplied charger because some others do not supply sufficient
current. USB computer ports will charge a tablet very slowly, sometimes
supplying less current than the tablet uses when turned on.
