The short life span of a laptop is because the BIOS system of the laptop misjudged the battery attack during the repeated charging and discharging of the battery. In this case, we can use the battery calibration method to make the remaining laptops fully play. There are two ways to calibrate the laptop battery.
Standard calibration method: use the battery calibration function in the notebook BIOS
Many brands of laptop computers have a battery calibration program built into the BIOS, called battery calibration. Directly enter this BIOS to end the battery calibration operation.
1. After the boot, the boot screen appears, press F2 to enter the BIOS menu; after the left and right direction keys, select to enter the power menu.
2. Enter the power menu, see the start battery calibration option, select and press enter to execute.
3. The screen turns blue and an English prompt asks you to plug in the power adapter of the laptop to charge the battery. When the battery is full, the screen prompts the user to disconnect the adapter. Then the laptop continues to discharge until the battery runs out.
4. This process will take a while. After the battery runs out, it will automatically shut down. The battery calibration process does not end until the charging is over (the charging indicator goes out).
Mobile phone battery calibration skills
The battery life of each mobile phone is indeed safe. According to the analysis number of its charging cycle, it is generally 400-600 times. But the user's usage habits will also have a greater impact on battery attacks. Bad usage habits, such as overcharging, overdischarging, high temperature environment, etc., will cause irreversible damage to the battery, prolong the battery life, and sometimes there may be safety hazards. In addition, through a closed application process, reasonable energy saving, every drop of electricity is used on the blade, and more meaningful work is done with limited electricity.
Develop good usage habits. Don't wait until the total power is reached before recharging, and don't wait until overcharging continues for a long time. Lithium ions like light charges. Of course, for an average user, it is sometimes difficult to remember when to charge or block the software.
