SAVE A SMARTPHONE BATTERY’S LIFE
Modern smartphone batteries last longest if they’re kept between about 50 and 70 per cent charged. As they get closer to their capacity, the electrical effort required to continue charging increases, and the risk of reactions that degrade the battery grows when it’s full. In other words, charging close to 100 per cent means treating the battery like an overstuffed suitcase. It’ll hold that huge amount, sure. But it’s tough on the zippers and fabric. If you want your battery to last, charge it intermittently.
