Problem:

The power consumption of the phone/tablet increases when the user makes a call.

Cause:

• During calls, the phone/tablet's RF components, screen, speaker, and receiver run continuously, consuming a substantial amount of power.
• If the network signal is unstable, your phone/tablet will increase its signal transmit power, resulting in higher power consumption.

Solution:

1. Keep the screen off during a call if possible, to effectively reduce power consumption of your phone/tablet.
2. Use a headset when making long calls, to prevent the receiver and speaker from running continuously and draining significant power.
3. It is recommended that you move to a location with good signal reception.

If this issue affects your normal use, back up your data and take your device and proof of purchase to an authorized Huawei Customer Service Center for assistance.
