How to judge whether the mobile phone battery is normal?

Battery is a key component of all digital devices. It is not only related to battery life, but also the key to the safety of the entire device. Then there are a few tips for judging the health of mobile phone batteries and eliminating hidden dangers. let’s see:

First of all, the easiest way is to observe the appearance of the battery. If the battery of the mobile phone is removable, it is very convenient. If the battery contacts show white or green corrosion marks, this is the first sign of battery failure. If some parts of the battery start to swell, you should be very careful not to continue using it.

Of course, battery aging bulges are not formed in a day. If you want to eliminate the hidden dangers as soon as possible, you can find out the small bumps that are not easy to detect through the rotation test. The method is very simple, find a horizontal surface, such as a desktop, a rotating battery. If the battery spins quickly, the surface is not flat.

Use software to check battery health level

For some mobile phones with a built-in battery, the more convenient way to check is through software. If you use an Android phone, you can enter “*#*#4636#*#*” in the dial interface, then enter the engineering interface, find the battery information item, you can see the detailed battery information, including battery health, you can refer to it.

If it’s an iPhone, you can use some management apps such as iBackupBot to check the number of charges and the actual battery capacity of the phone. If the total power loss exceeds 20% of the original power after being fully charged, you should consider replacing it (the lithium battery will lose 20% of the power after being charged and discharged 500 times).
