My HUAWEI phone's/tablet's power consumption is high on trains and high-speed trains

Problem:

The phone's/tablet's power consumption is high on trains and high-speed trains.

Cause:

On a high-speed train, a phone/tablet increases the frequency of network switchovers and network searches. When moving, the device switches between multiple mobile network base stations to ensure smooth communication, which results in an increased power consumption. When data services are enabled, apps are frequently connected to the Internet, which further increases power consumption.

Solution:

It is recommended that you turn off mobile data when you do not need to use it.
