Hi. Extremely sorry for the delayed reply. The battery life will depend on two variables
- The size of the battery installed - Mobicel sadly does not mention the size (in mAh) of the battery install
- Usage and settings - brightness, background running apps, internet based apps and voice calls contribute much on the extend to which a battery will discharge from full to empty.
I you already own this tablet, you could install a certain app that would give you an estimation that should closely answer your question.
