But other than these quick power-saving fixes, there's not much you can do to prolong your battery's charge. For example, charging your phone in short bursts isn't going to help your battery keep a charge for longer, even though many sites claim this is the case, Gordon told Live Science. And perhaps you've heard the old wives' tale that leaving your phone plugged into the charger overnight will somehow damage your battery, That isn't true either, according to Shearing. Shearing said. Major cellphone manufacturers build "battery management systems" into their products to ensure that phone batteries don't charge indefinitely, which would be a serious problem if it were allowed to occur. These systems include a circuit board and accompanying software, which together serve as a sort of mini-computer that regulates your phone's battery. These battery management systems not only ensure that your phone doesn't accept too much charge, they also make sure it doesn't release too much of its charge.
Draining a Li-ion battery too much can damage the battery, leading to a "reduction in lifetime," said Shearing, who noted that modern cellphones turn themselves off before the battery drains beyond this point of no return. But while today's cellphone battery management systems are smart, the batteries they manage are still big, bulky and not quite long-lasting enough for many users. This is the problem that companies like Apple are trying to solve with their battery-boosting phone cases. If you're holding out for a cellphone with a super-long battery life, you may be waiting a while longer. Shearing said the next major energy storage breakthrough will likely be the emergence of lithium-air batteries that "breathe" out air as they charge. And air-breathing cellphones probably won't be available for purchase for at least 10 years, he said. So don't hold your breath. Follow Elizabeth Palermo @techEpalermo.
