Check the battery life.
First of all, we can check the battery life through the settings of the phone. Go to the phone settings and click "Battery and Performance". In "Battery Life", you can see the usage time of the mobile phone from the last charging to the present. If the service time is short, the battery life is good.
Check the battery health.
Besides the use time, we can also check the health of the battery. Enter the phone settings, click "Battery and Performance", and you can see "Battery Health" under "Battery Service Time". If "Good" is displayed, the battery life is good; If it is displayed as "average", it means that the battery life has decreased; If it is displayed as "Need to be replaced", it means that the battery life has been seriously reduced and the battery needs to be replaced in time.
Observe the battery charging.
In addition to checking battery life through mobile phone settings, we can also judge battery life by observing battery charging. If the charging speed is slow, it will take longer to fully charge, indicating that the battery life has decreased; If the phone heats up seriously when charging, it also means that the battery life has decreased.
