Ouch, battery test, what happens when 4 CPUs are hibernating?

The easiest way: use up your cell phone battery completely, then try charging it for 8 hours.

The other two are available online, you can try them. 1. Freezing method: Place the mobile phone battery that is close to the usage limit in the refrigerator, freeze it for three days, then take it out and continue to use it. The battery will last longer than before freezing! This is recently the most popular method of repairing old batteries on the Internet. ----The explanation is: The process of using the mobile phone battery is a process of charging and discharging. During this period, the negative charge and positive charge of the battery collide. The reason batteries are becoming less and less durable is that at normal room temperature, the internal kinetic energy of the electrons is relatively imimportant, so the battery is in an active state and leaks are 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 their interface, will change significantly, causing the battery to be temporarily inactive and current leak. to decrease. Therefore, after recharging, the phone battery standby time will increase.

2. The second statement is that using an eraser to wipe the metal contact surface between the mobile phone battery and the mobile phone can make the mobile phone battery in better condition.

This principle is relatively simple to understand. The metal surface will oxidize over time, natural contact will be less severe, and battery life will be shorter. I had the experience with my phone battery poSamsung table. Instead of using an eraser, I found a piece of polishing sandpaper, folded it twice, and used the sharp corner to polish the brass contacts of the cell phone battery several times , then I used the sharp corner to polish the brass contacts of the cell phone battery. I used it neat. I wiped it with a cloth, unloaded it completely and then charged it. This time the battery lasted a day longer than before, and it seemed effective.

1. Before charging, please use a soft, dry cloth to clean the contact points on both ends of the battery. Try to keep the contact points on both ends of the battery as clean as possible to ensure that the battery is intact. the battery is fully charged. If the battery electrode is oxidized, it should be wiped clean. If it is severely oxidized or damaged, the battery should be replacedimmediately replaced by a new one. After removing the battery, use an eraser to clean the contacts (brass parts) of the battery, then charge it and try it. 2. Lithium batteries are easy to activate. After 3-5 normal charge and discharge cycles, the battery can be activated and restored to its normal capacity. Due to the characteristics of the lithium battery itself, it has almost no memory effect. Therefore, the user's new lithium battery does not require any special methods or equipment during the activation process. Not only is this true in theory, but the “natural activation” method of loading using standard methods from the start is best. 3. You can try the following methods: 1) Wrap the battery in newspaper, then put it in a plastic bag and put it in the freezer for three days (the newspaper can absorb excess water) 2 ) Afters three days, take it and store it at room temperature for two days. 3) 2 Day by day, charge the battery and insert it into the camera for testing (it is estimated that 80-90% can be saved)
