How to fix the aging battery of the mobile phone by yourself

1. mobile phone battery repair method 1 wrap the mobile phone battery that is about to be scrapped with newspaper, wrap it in two layers of plastic wrap outside, then put it in the refrigerator freezer, take it out after three days, remove the package and put it in a cool place to dry for two days, and then charge it. a professional explanation of this mobile phone battery repair method ( source network ) : the use process of a mobile phone battery is a process of charging and discharging , during which the negative and yang charges in the battery collide with each other . The reason why the battery will become more and more useless is because at normal room temperature , the kinetic energy inside the electrons is relatively large , so the battery is in an active state , and the leakage is relatively frequent . When the battery is placed in a low-temperature environment, the microstructure of the lithium film and electrolyte on the surface of the lithium battery, as well as their interfaces, will change significantly, resulting in temporary inactivity inside the battery and a reduction in leakage current, so after charging again, the waiting time of the mobile phone will increase.

2. Mobile Phone Battery Repair Method 2 Use a clean eraser to gently wipe the metal contact surface between the mobile phone battery and the mobile phone, this method can effectively improve the use of the mobile phone battery. The principle is that the metal surface of the mobile phone battery after a long time of use has a certain degree of oxidation, resulting in poor contact and shorter battery use time, and the oxide layer on the surface can be erased with an eraser , so that the contact between the battery and the mobile phone becomes better. a lei believes that the second method of repairing the battery of a mobile phone is more suitable for the kind of mobile phone battery where the problem is not very serious .

3. Mobile phone battery repair method 3 Use a battery that is close to scrapping to completely discharge, and then recharge to activate the battery . The specific method is as follows: two wires can be found and connected to a 1 . a small 5-volt bulb , then connect both ends of the wire to the positive and negative poles of the battery , at this time the bulb will emit some faint light , wait until the bulb is completely off and then charge it , so as to improve the performance of the battery . note : the mobile phone battery repair method is not very effective , but it is still somewhat useful .
