Who wants to make an urgent dash to a power outlet to rescue their laptop battery? That’s no fun, especially if you’re working a crowded convention center, tapping away at an airport gate, or even lounging on a tropical beach. Luckily, modern laptops are much more efficient than their predecessors. Nowadays, even inexpensive desktop-replacement laptops and some gaming behemoths can last for more than eight hours on a single charge. Some ultraportables can endure for 14 hours or more.
Still, the inconvenient truth is that the battery in your PC or Mac laptop won’t last as long as the manufacturer advertises unless you pay attention to some key factors: your power settings, how many apps you’re running, even the temperature of the room in which you’re working. The good news is that none of this requires very much work to sort out, once you know which settings to adjust. Let’s take a look at the highest-yield ways to get the most out of your laptop’s battery.
