We can also check the performance of the charger during use. It is normal for the battery to have a slight temperature rise in the later stage of charging, but if the battery is obviously hot, it means that the charger has not detected that the battery is fully charged in time, causing overcharge, which is detrimental to the life of the battery.
Although many chargers are not overcharged, they have the problem of insufficient charging, which is directly reflected in the short battery discharge time, that is, the short standby talk time of the mobile phone. For users who use the original random new battery, you can compare the approximate reference time provided in the manual for comparison. If the reference value is obviously different from the actual use, there is reason to suspect the problem of the charger. Of course, the quality of the battery and the use of the mobile phone are not ruled out. Environment and other factors.
