When Huawei's battery health reaches 86%, it can still be used normally and does not need to be replaced. Only when the maximum capacity ratio of the battery drops below 85%, the running performance of the mobile phone may be affected. You can check the current state of the battery through "Battery Health" in the phone settings to determine whether it is necessary to replace the battery.
Therefore, if the battery is in good condition, there is no need to worry about the power problem, and there is no need to replace the battery frequently.
