3.不要禁用所有位置服务

Many apps that use your location do so only intermittently. Even using the Maps app for short navigation sessions doesn’t use more than a few percent of your battery’s capacity — and having the phone’s screen continually on is a big part of why navigation uses a lot of power.

很多应用都只是间歇获取你的位置。就算使用地图应用做短期导航，也不会耗费很多电能——让手机屏幕一直亮着才是导航功能费电的原因。

In other words, don’t disable all of your phone’s location-based features just to extend your battery life. You won’t see a big jump in use time, but you may end up disabling — and subsequently missing — useful features. Instead, check (using the tips above) to see if any of apps consuming the most battery life also track your location. If so, and if you don’t need that location tracking, consider disabling it for those apps.

换言之，不必为了省电禁用手机里所有和位置有关的应用。这样不会大量增加使用时间，但却会让你错过很多有用的功能。你可以根据上文的提示，检查哪些耗电最多的应用在使用定位功能。如果你不需要它的定位功能，就可以关掉。
