Over the last few months my nexus 7 has had appalling battery life, and has taken a whole day to charge up 17%, which is unheard of. I was surprised as i was careful to not leave the device on charge for long periods of time etc etc. The battery would also go down from the 17% to 0% in a mere 30 minutes. I was sure this must have been a fault, so i returned the item to Argus, hoping for a easy solution, however their excuse for not repairing/replacing the device was that my device had "external damage" (my screen had unfortunately cracked several days before. I argued that this was not a valid point, as surely a damaged screen could not effect the battery? I may be wrong however, does anyone know?
