SPEED UP CHARGING OF YOUR PHONE

Just like everyone else you probably want your phone to charge up as quickly as possible (even more so if you're in a rush). Put it in aeroplane mode and it will use much less battery life and thus charge more quickly. 

So whenever you are in hurry to go somewhere outside but the battery of your phone is too much low then you should activate the aeroplane mode so that your phone will be quickly charged.
