The latest smartphones boast improvements in battery life, with bigger batteries, longer battery life overall, and features like battery-saver mode. But there are still features and functions that can drain your battery more quickly than others, even if the phone is in standby mode. One feature you might not realize is draining your phone on standby, for example, is having mobile data always active. Turning this feature off prevents the phone from constantly trying to connect to a mobile network when you’re on Wi-Fi. But it also means the phone can take longer to connect to a cellular network once you leave a Wi-Fi zone. Plus, it requires entering developer settings to turn off.
