Problem:

The user wants to confirm that a new phone/tablet battery, replaced through an unofficial channel, is genuine.

Cause:

An unofficial channel does not provide official HUAWEI batteries, and the quality of their batteries cannot be guaranteed.

Solution:

1. A Huawei store can help check the authenticity of the battery on certain models (which you can determine in the store). If the battery life significantly decreases after an unofficial replacement, back up your data and take your device and proof of purchase to an authorized Huawei Customer Service Center for assistance.
