15.13 Why does my phone sometimes repeatedly restart
after it is connected to a charger and powered on?

When your battery is over discharged, the power supply is insufficient when your phone is connected to a small-load charger,
resulting in insufficient current that causes the repeated restarts of your phone. Use the 5 V 2 A charger that comes with your
phone to provide sufficient current for your phone.

15.14 How do I save my phone's battery power?

1. Set your phone to close unwanted applications when you turn off the screen.

Choose

Settings

>

Power saving

>

Protected apps

and deselect the power-intensive applications and other unwanted

applications. Then the deselected applications will be automatically closed after the screen is turned off.

2. Adjust your screen brightness.

To turn on ROG technology:

Go to

Settings

>

Display

>

Brightness

and drag the slider to adjust the screen's brightness.

3. Reduce the time for the screen to go to sleep when the screen is idle.

Go to

Settings

>

Display

>

Sleep

and set a shorter time for the screen to go to sleep.

15.15 Will the indicator respond when my phone's battery
level is less than 10%?

When the battery level is lower than 10% but higher than 2%, the LED is turned off, the
indicator does not blink, and event reminding will not be affected.

When the battery level is lower than 2%, the indicator is blinking red.

15.16 What can I do if my phone's standby time is short?

1. Set your phone to close unwanted applications when you turn off the screen.

Close unwanted power-intensive applications under

Settings

>

Power saving

>

Background

power-intensive apps

. Alternatively, you can choose

Settings

>

Power saving

>

Protected

apps

and deselect the power-intensive applications and other unwanted applications. If some

applications are needed in the background, they can remain unclosed. This method helps save
battery power after the screen is turned off by reducing the number of power-intensive
applications that are running in the background.

2. Adjust the screen brightness.

Go to

Settings

>

Display

>

Brightness

and drag the slider to lower the screen's brightness.

Use this method based on your actual situations. The screen consumes relatively much power,
so this method can help reduce the power consumption of the screen.

3. Close unwanted background applications.
