Help!!! Battery curve jumps up and down
I'm using a new Galaxy Tab 3 T210 and noticed, that the battery goes rapidly down when in use (30 min. navigation, down from 100% to 10%), but "recovers" rapidly, when in standby mode (from 10% back to 65% after one hour standby).
I newer had any similar problems with other devices, which steadily went down to zero.
This one "jumps" up and down.
Do you have similar experiences or should I send this tablet to Samsung for check and repair?
They (Samsung) don't gave me a helpful answer, just factory reset or send-in...
