    • Reasons for short standby time of mobile phones and their solutions

    • Профессионального характера:

    Power consumption is relatively faster on smart phones than on functional phones. Normal standby time for smart phones is generally about 2 days (depending on the specific use conditions);

    Running a certain amount of applications in the background during standby will speed up the power consumption;

    The power-hungry function is not closed in time, such as WiFi, GPS and Bluetooth, and it cannot be connected after it is turned on. It is always in a  connection searching state, causing the standby time to be shorter. So it is recommended to have  those functions turned off during standby.

    After downloading and installing a third-party software or updating a certain software, the power consumption rapidly increased and the standby time becomes shorter. It is recommended to uninstall such software;

    If the firmware version such as the beta version is not stable, it is recommended to back up the phone data and restore to factory settings or conduct flash processing.

    If the above said operations can't solve the problem, please send your purchase invoice, warranty card and mobile phone to KXD customer service center for testing.
