I know this is a very stupid question. Even I know the answer! The problem is: my mum keeps saying that using up to 28% is bad. You can only use until 40%. VERY STUPID!!! I can't fine a good explanation because the she says the owner of the store where she bought the iPad said so. I can't proof anything because she says I know NOTHING! I really need a good answer for this.
Plz help! She's being a maniac just over this stupid iPad
>>> Is using less than 20%-10% on your Apple device effect anything?
