About Charge and Games
I have iPad mini 3. When I plug and charge it, the battery drain down slowly while I play the Minecraft game.
I use 10w power adapter and 3m long cable. The battery design capacity is 80%.
Is it because of the battery needs to be replaced?
or that 3m long cable which some power is lost during the transmission?
Or if I buy 12w power adapter may it fix my issue?
