Cause:

Map and navigation apps keep the phone/tablet screen on and use GPS, voice, and data services, which consume much power.

Solution:

To preserve more power for your phone/tablet, try one or more of the following methods based on your needs:

1. Download offline maps and navigation packages in advance to reduce power consumption caused by GPS and data services during navigation, as well as save mobile data usage.

2. Close any unnecessary background apps in a timely manner.

3. You can also lower the screen brightness and media volume during navigation. If the screen brightness and volume stay high for an extended period of time, the battery will drain faster.
