If you've ever needed to
charge your phone but known you had to leave an outlet behind in just a few
minutes, here's a way to get the most possible charge for your precious time at
a charger: Put your phone in Airplane Mode first.
Putting your phone into
airplane mode turns off all of the wireless radios inside, so while you won't
be able to receive calls, use data, or use GPS, you also won't be fighting
background processes that use those radios for power while your phone is plugged
in. The end result is your phone will charge a little faster, and you'll walk
away with a bit more power in your battery than you would otherwise. Of course,
you could get a similar effect by just turning your phone off (sans power
required to shut down/start up), but this is a bit easier.
