Lithium battery manufacturers explain how to repair mobile phone lithium batteries and restore the vitality of mobile phone lithium batteries

According to news from battery.com, almost everyone has mobile phones nowadays. This electronic product is very common, but after a period of time, the standby time of the mobile phone will become shorter and shorter. Is there any way to restore it? Of course, the lithium battery manufacturer is in Here are a few methods to achieve lithium battery capacity repair. The more common and easy to operate methods: 1. First of all, mobile phone lithium battery is a low-power energy polymer lithium battery, because the mobile phone needs a longer standby time, so the battery will continue to maintain a very low level when the mobile phone is in standby mode. If the power output is to be consumed as much as possible. It is necessary to ensure that the contact points between the battery and the mobile phone motherboard are clean. When the contact points are dirty, you can use an eraser to clean them. Principle 1: The metal surface of the lithium battery will be oxidized to a certain extent for a long time (if the surface is dirty, or this speed will be accelerated), oxidation will directly lead to poor contact between the mobile phone battery and the mobile phone, and the life of the lithium battery It will become shorter, but the rusty material on the surface that can be wiped with an eraser or other cleaning tools will make the battery and mobile phone contact better, and the use time will be restored after the resistance is reduced. All devices using lithium batteries can follow this Method to check. 2. Wrap the lithium battery of the old mobile phone with plastic wrap, as many layers as possible, to ensure that the main body of the lithium battery is in a vacuum state, and then put the wrapped lithium battery in the quick-freezing of the refrigerator for 48 hours, then take it out and let it out. Naturally return to normal temperature, and then release the cling film. (Note: Do not unwrap the cling film in advance. When the frozen lithium battery naturally heats up, the condensation of water on the surface may cause the battery to short-circuit. Principle 2: Low temperature can change the lithium The electrolyte inside the battery promotes the chemical reaction of the battery that has just been frozen. The process of using a lithium battery is actually a process of charging and discharging. During this period, the negative and positive charges in the battery collide with each other. The battery becomes more and more empty. Because electrons have more kinetic energy at normal room temperature, the battery is active and leaks relatively frequently. When the lithium battery is in a low-temperature environment, the microstructure and interface of the lithium film and electrolyte on the surface of the lithium battery will be affected. Significant changes have occurred, causing the battery to be temporarily inactive and the leakage current is reduced. So after charging, the standby time of the mobile phone will increase. 3. Let the lithium battery that is close to being discarded completely discharge, and then recharge the battery to activate it. Method: Deep discharge, using up internal power to achieve deep charging, requires some unconventional methods. A special device connects the mobile phone to a low-voltage light bulb, and the energy of the battery is transferred to the light bulb until the light bulb lights up. 'The phone needs low The voltage will drain the battery slowly. Under normal circumstances, when the rated voltage is less than 3.6 volts, the phone will automatically shut down.'The battery life of the mobile phone after charging is longer. But this operation prohibits skipping the lithium battery protection device ( The circuit board installed on the lithium battery), connect the discharge directly on the electrode of the lithium battery. Excessive discharge of the lithium battery that loses its protection function may cause damage to the battery. The lithium battery with multiple strings and multiple parallels is not suitable for this discharge method. XRecovery2 restore the phone battery 1. Jailbreak, or get root permission, and install xRecovery22. Under normal circumstances, the power can reach 100%, use direct charging instead of USB charging 3. Do not unplug the power cord and restart the phone to enter xRecovery4. In the recovery mode , Find the advanced option -u003e Wipe battery status -u003e Yes, delete the battery status 5. Directly unplug the battery (do not unplug the charging cable); 6. After a period of time (more than ten seconds, grab it yourself) connect the battery, don't The phone will start by itself for more than one minute. 7. When the phone is turned on and enters the system, you will find that the battery level is displayed at about 88% instead of 100%. 8. Continue to charge to 100%. 9. Repeat steps 2-8 4-5 When the phone starts to enter the system (step 7), the battery shows 100%, and the battery is repaired successfully. Phone battery maintenance 1. Charge according to the standard time and procedures, even the first three times; when the phone battery is too low When prompted, try to start charging as soon as possible. Under normal conditions, lithium batteries should try to avoid excessive discharge, such as mobile phones, try to avoid using less than 20% of electricity; 2. Try to avoid charging before going to bed, because it is charged before going to bed. The time is long, and the voltage at night is unstable. The voltage at night in many places is relatively high and fluctuates greatly, which has a greater impact on the battery. 3. The activation of the lithium battery does not require special methods. For newly purchased mobile phones, the lithium battery will be naturally activated during normal use of the mobile phone. The above method is applicable to the maintenance of all lithium batteries.
