I recently got an onda V10 3g tablet. I have been trying to test the battery's capacity. it is said to come with a 6000mah battery however I have watched it discharge so rapidly from a 97% to a 90% in minutes. on getting a Du battery saver app I checked the battery details and it indicated a maximum capacity of 1000mah. is something wrong with my battery? or its just the app misbehaving?
