The Best Time to Charge Your Phone

You may be in the habit of plugging in your smartphone to charge it whenever your battery gets low or, simply whenever you have time. But overcharging a battery can hurt its lifespan.

A new study suggests there’s actually a better time to charge your phone’s lithium-ion battery, at a point where it is most efficiently able to accept power. If you want your phone to charge faster, let the battery dip super low before you plug it in.

“Generally, a battery can accept higher charge rates at a lower state-of-charge percentage than it can at higher percentage,” Mark Carlson, an engineer at Motorola, told Forbes.com. “So a battery at 10 percent can generally accept higher charge current than a battery at 50 percent.”
