Smartphones are miraculous devices – powerful, pocket-size computers that have reshaped modern life so completely it's hard to imagine a time when you unfurled a paper map, popped a CD into the car stereo, or wondered what a friend's new baby might look like (spoiler alert: like a baby). There's a price, though, for all that personal digital empowerment: actual power, sucked from your phone's battery by new apps and features, at a rate that seems to outpace the device-makers' ability to build more energy-dense batteries.
There is a relatively simple solution to energy hemorrhage. You can familiarize yourself with what's arguably the most-used gadget in your life, and plug the leaks by toggling settings, getting new apps, and knowing what's going on now on your phone. Here are ten tips to help eke more electrons out of your smartphone.
Turn on Airplane Mode When You're Asleep
The primary function of airplane mode is based on a superstition – that preventing a phone from trying to emit or receive radio waves will avert some sort of freak communication glitch, and convince a perfectly good aircraft to go into a tailspin. The mode's real value is in preserving battery life, since a phone that isn't searching for data or cell reception is using significantly less energy. So unless you need to be reachable at all hours of the night, when you're sleeping at home, pretend you're 30,000 feet in the air, and activate airplane mode. The phone will still work as a clock (and alarm), but won't be pointlessly leaking power.
