Use This Simple Trick to Charge Your Phone in a Flash
Especially when you’re on the go, checking your phone’s battery life may not be the first thing on your mind; but leaving it to die can be crippling, as the average smartphone can take up to 2 hours for a full charge. If you need your phone and you need it now, just use this simple trick:
Switch your phone to Airplane mode while you charge.
For iPhones: go to Settings > Airplane Mode > Slide “On”
For Android: Swipe down at the top of the screen > Swipe Left > Tap “Airplane Mode”
The difference in charge time isn’t earth shattering, but you do get to 25% significantly faster.
