Tablet Losing Battery While Off

[owensdj]

Is it normal for a Lenovo A10-70 tablet to lose about 1% of its battery charge a day while turned completely off? This is starting from a full 100% charge.

How long was it? 1% per day sounds normal if it's just for 2-3 days (probably a calibration issue or drains while turning off-on, which is no big deal).

If it's two months and it's down to ~30%, then something is probably draining it just a little and preventing the tablet to be completely off. What's the OS on this tablet?

Note that the best way to store (connected) battery inside a device that's turned off is about 50% charge. This is why when you bought a new device and turn it on it's usually around 50%.

A good way to minimize discharge is to place the tablet in Airplane Mode before turning off.
