3. Avoid disabling all location services.

3.不要禁用所有位置服務

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.

很多應用都只是間歇獲取你的位置。就算使用地圖應用做短期導航，也不會耗費很多電能——讓手機屏幕一直亮著才是導航功能費電的原因。

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.

換言之，不必為了省電禁用手機里所有和位置有關的應用。這樣不會大量增加使用時間，但卻會讓你錯過很多有用的功能。你可以根據上文的提示，檢查哪些耗電最多的應用在使用定位功能。如果你不需要它的定位功能，就可以關掉。
