After the mobile phone is used for a long time, the battery is prone to malfunction. If the battery is damaged, it will cause the mobile phone to not work normally, and even cause the mobile phone to stop. Now, let us come to Deji battery manufacturers to teach you how to judge whether the mobile phone battery is damaged.
1. Judging from the appearance of the battery
If the battery is raised, dented, etc., it can be judged that the battery is likely to be damaged.
2. Voltmeter to measure battery voltage
Use a voltmeter to measure the voltage. Under normal circumstances, when the battery is fully charged, the voltage value is about 4.2V, and the voltage after the battery is used up is about 3.6V, so if the voltage after charging is still 3.6V, It can indicate that the battery has been damaged.
3. Software operation status
If you use the software in the mobile phone and find that the software always crashes and the running speed is very slow, you can also judge that the battery is broken.
4. Charging time becomes longer
If the battery charging time becomes longer than before, it can be judged that the battery is about to break down.
