2. Super-fast Charging with the Single press of a Button
Strapped for time and need to be out in a jiffy? Wait a minute; you didn’t charge your phone last night; what a nightmare.
Fortunately, according to plenty of forums on the net (though there’s never been an affirmation from Apple), turns outputting your iPhone 7 (and higher versions) on flight mode helps increase the charging juice.
By engaging the Flight Safe mode, you’ll be limiting the naughty shadow battery drainers such as Wi-Fi and data, making the battery less strained as it strives to get some more juice.
