why my Huawei MateBook X Pro Battery capacity loss is detected by third-part app?

Your computer uses a lithium-ion polymer battery, which negatively correlates with the number of charge/discharge cycles, that is, the battery capacity will gradually decrease as the number of charge/discharge cycles increases.

Huawei batteries are subject to strict screening and control, and undergo rigorous testing during the production process to ensure product quality. Therefore, even if the battery is factory new, it will still have a very slight capacity loss due to testing. However, there will be no case where the actual battery capacity is significantly lower than the design capacity.

Third-party apps may also experience capacity-reading errors due to algorithm differences.

It is recommended that you continue charging your computer for 30 minutes or more after it is fully charged (displaying 100%) so that third-party apps can obtain more accurate battery capacity values.
