New battery in iPad mini 4 is draining just as fast as old one - lasts barely 2 hours of ordinary browsing
Now on 2nd new battery and no difference. Service bloke (not Apple specialist) says it is a mainboard issue but not being specific. Is there a simple way to test the mainboard.
Am hoping he isn't putting dud batteries in - both seem not to have made any improvement.
Any suggestions most welcome.
Thanks in advance.
