What to do if the battery of smart phone is not durable? How to repair if the battery of mobile phone is not durable

Four seas network: mobile phones update and iterate faster now. It takes a little longer. The battery life is greatly reduced, and even the power will shrink. What about the battery life? Let's teach you some simple and practical methods!

The first one is the freezing method: put the cell phone battery close to the use limit into the refrigerator, freeze it for three days, and then take it out for further use. The use time of the battery is longer than before the freezing! This is the most popular method of repairing the old battery on the Internet recently. I'll take this first!

Find out the earliest Motorola battery. It's still the V70 and rotating screen seven years ago. Now I'm afraid that it can only be used as a toy for children. The battery inside is original. After charging the mobile phone, it will run out of power for more than two days. Take out the battery, wrap it with a plastic film for two layers and then wrap it with a newspaper paper for two layers. This is for moisture absorption and moisture-proof. Put it in the refrigerator freezer for three days, and then take it out Take off the package and let it dry for another two days. Recharge it and put it into the mobile phone. This time, the mobile phone doesn't have power until the third night. It seems that this method is really effective.

The professional explanation of this method on the Internet is that the use of mobile phone battery is a process of charging and discharging, during which the negative and positive charges in the battery collide with each other. The reason why batteries become more and more useless is that the kinetic energy inside the electrons is relatively large at normal room temperature, so the batteries are 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 on the surface of the lithium battery and the electrolyte, as well as the interface between them, will change significantly, which will cause the battery to be inactive temporarily and reduce the leakage current. Therefore, after recharging, the waiting time of the mobile phone will increase.

Second, wipe the metal contact surface between the mobile phone battery and the mobile phone with an eraser, which can make the use of the mobile phone battery better.

It's easy to understand that the metal surface will oxidize after a long time, and the natural contact will be almost the same, and the battery will take a short time. I did the experiment with my Samsung cell phone battery, and I didn't use the eraser. I found a piece of polishing sandpaper, folded it twice, polished the brass contact piece of the cell phone battery with the sharp corner part, wiped it with a clean cloth, discharged it fully and charged it again. This time, the battery was used for a day more than before, and it seems to be effective.

The third is to completely discharge the batteries that are close to the end of life, and then recharge the batteries to activate them.

It seems that there are not many people who have tried it. I have a battery on hand. It is the backup battery of Samsung mobile phone. It may be improperly used. It can only be used for less than a day. It has been left idle in the drawer for more than two years. I found two wires, connected a 1.5V small bulb, and then connected the two ends of the wire to the positive and negative poles of the battery. The bulb barely emits a little light. It only lasted less than half an hour, and the bulb no longer lights up. I charged it for another two hours, and put it into the hand machine. This time, I kept it for more than a day before the black screen of the mobile phone. So, this method can still work It's more or less useful.

Three methods, one by one. The first two are more convenient. If you want to try them, you can try them. However, if you have money, you may think it's a rather troublesome thing. If you think about the mobile phone, it's also a relatively expensive commodity. Thousands of yuan of mobile phones have been bought. It may be more practical to buy one or two high-performance batteries for backup. If the original electricity is too expensive, you can buy them Brand electricity is actually quite a good choice. Japan's imported brand has radiation protection function, which can be used for more than half a day longer than the original one. The addition of radiation protection function can make my family healthier. With two batteries in hand, you don't have to worry about your cell phone running out of power when you meet a business trip or something!
