iPad Mini - wifi connection - using tip
Today I've bought iPad mini. Since, this is first iPad I have, I am wonder should I leave wifi on the whole time, or it is better to turn it off? I have skype, viber and other programs, whose should be online. I know I have to keep wifi on if I want them to be online, but is this harmful for the iPad, to wifi be always on?
And what happens to iPad when it goes to sleep? Is wifi still turned on, or it goes off, too?
And how it acts in scheduled do not disturb mode?
