Cell phone battery repair Daquan comprehensively enhances the "life" of mobile phones

According to Battery.com.cn, mobile phones are now very popular, and they are the most frequently used electronic products in daily life. But everyone will feel that after using a mobile phone battery for a period of time, the standby time will come. The shorter, this is very relevant to the quality of the battery and everyone's use. Then, after the mobile phone battery has been used for a short period of time, we have no way to let him recover. Xiaobian also check some related information, sort out some mobile phone battery repair methods, I hope to be helpful to everyone.

Common mobile phone battery repair methods:

1. Use a clean eraser or other cleaning tool to gently wipe the metal contacts on the lithium battery and the metal contacts on the phone to help with the charging status and power lasting.

Principle of lithium battery repair method 1: The metal surface of the lithium battery used for a long time will have a certain degree of oxidation, resulting in poor contact between the mobile phone battery and the mobile phone. The lithium battery is used for a shorter period of time, and can be wiped with a rubber plaque or other cleaning tool. In addition to the rusting material on the surface, the battery is in good contact with the mobile phone.

2. The old mobile phone lithium battery that will be automatically shut down will be wrapped tightly with plastic wrap. When wrapping, try to serve as much as possible. There are three layers inside and outside to ensure that the battery is in a vacuum state. Then, the three-layer newspaper on the outside of the plastic wrap is used to completely seal the lithium battery. After being placed in the frozen layer of the refrigerator, after 48 hours, the battery was taken out, and the six-layer paper film wrapped outside was removed one by one. The lithium battery was not swollen or deformed due to freezing. After cooling for a while, then charge.

The low temperature can change the electrolyte inside the lithium battery and promote the chemical reaction of the battery that has just been frozen. The use of lithium batteries is actually a charging and discharging process. During this period, the negative and positive charges in the battery collide with each other. The reason why the battery is becoming more and more useless is because under normal room temperature, the internal kinetic energy of the electron is relatively large, so the battery is in an active state and the leakage is relatively frequent. When the lithium battery is placed in a low temperature environment, the lithium film on the surface of the lithium battery and the microstructure of the electrolyte, and their interfaces will change significantly, resulting in a temporary inactivity of the battery and a decrease in leakage current. Therefore, after recharging, the waiting time of the mobile phone will increase.

3. Discharge the lithium battery that is nearly scrapped and recharge it to activate the battery. The specific method is: deep discharge of the mobile phone, that is, by exhausting the internal electric energy, to achieve a deeper degree of recharging, which requires some unconventional methods. Connect the phone to a low-voltage small light bulb with a specific device, and the internal power of the battery will be transferred to the small light bulb until it is completely illuminated. “The mobile phone needs to slowly run out of power through a lower voltage. Under normal circumstances, if the mobile phone is connected below the rated voltage of 3.6 volts, it will automatically shut down.” After the battery is discharged, the rechargeable battery can be used again. Long time.

Deep discharge of the mobile phone is to achieve deeper recharge by depleting the internal power, which requires some unconventional methods. Try to connect the phone to a 1.5V small light bulb, and the internal power of the lithium battery will be transferred to the small light bulb until it is all light. “The mobile phone needs to slowly run out of power through a lower voltage. Under normal circumstances, if the mobile phone is connected below the rated voltage of 3.6 volts, it will automatically shut down.” After the battery is discharged, the rechargeable battery can be used again. Long time.

Repair your phone battery with xRecovery2

1. The phone must be ROOT and xRecovery2 is already installed.

2, the normal charge to 100%, please use direct charge, do not use computer USB charge

3, do not pull the power cord, restart the phone into xRecovery

4, in the recovery mode, find Advanced options --> Wipe Battery Stats --> Yes, delete the battery status

5. Unplug the battery directly (do not pull the charging cable);

6, after a while (more than ten seconds, grasp it yourself) put the battery on, do not move, the phone will be started for more than a minute

7. After the phone starts to enter the system, you will find that the battery level is displayed at around 88%, instead of just 100%.

8, continue charging to 100%

9. Repeat steps 2-5 for 4-5 times. When the phone starts to enter the system (step 7), the battery shows 100% indicating that the battery repair is successful.

Mobile phone battery maintenance

1. Charge according to the standard time and procedure, even if it is the first three times; when there is a low battery power prompt, you should start charging as soon as possible;

2, try to avoid charging before going to bed, because the charging time before going to bed is longer, and the voltage at night is unstable, the night voltage in many places is relatively high and fluctuating, the impact on the battery is greater.

3. The activation of the lithium battery does not require a special method. The lithium battery will naturally activate during normal use of the mobile phone.


Introduction:

 Brake fluid detection pen is based on the change in conductivity to determine the moisture change brake fluid. It shows clearly the extent of moisture contained by the light-emitting diode, high moisture content will lead to lower boiling point, affect braking performance. Red indicates the brake fluid needs immediate replacement, green represents good condition, yellow indicates the state is acceptable but soon replaced.

 

Features:

Five LED indicators show the test results more accurate.

Testing DOT 3, DOT4, DOT5 brake fluid

Press the switch to turn on the power, the green LED light that represents the battery properly, the green light does not shine on behalf To replace the battery

Automatic shutdown

 

Specification

1, check the car brake oil quality

2,5 LED lights display the percentage of moisture content in brake fluid

3, auto power off

4, 1 LR03 AAA batteries (not included)

 

 

1, the green LED lights = water content in the brake fluid H2O <1.5%, brake fluid qualified

2, the yellow LED lights = brake fluid water content H2O = 1.5% to 3%, can continue to use, test again six months later

3, the red LED lights = water content in the brake fluid H2O> 3%, can not continue to use the brake fluid needs to be replaced

Red LED: change brake fluid

4, LED red flashing: battery replacement

5, LED yellow: low moisture content, check again in six months

6, LED green: brake fluid lines / cell row
