Laptop battery and mobile phone battery calibration method

Abstract: Whether it is a mobile phone battery or a laptop battery, it has special power consumption for a long time. The result of the three-day one-charge mobile phone cannot be supported for one day. At this time, you can correct the repair. Do you know how to correct these batteries? Everyone illustrates the laptop battery calibration method and the Android phone battery calibration procedure.

How to correct laptop battery power

Method 1, standard calibration method: use the battery correction function in the BIOS

Many brands of laptops integrate battery-corrected programs in their BIOS. The general English phrase is called "BatteryCalibration", which means "battery calibration." Directly enter the BIOS to complete the battery calibration operation, take the Asus notebook as an example, simply talk about how to operate, other books operate similarly.

Step1: Power on, press [F2] to enter the BIOS menu after the startup screen appears; use the left and right arrow keys to select to enter the Power menu.

Step2: Go to the Power menu and you will see the “StartBatteryCalibration” option, select it and press Enter to execute.

(1) Select the "Battery Correction" program

Step3: At this time, the screen will turn blue, and there will be an English prompt to plug in the notebook's power adapter to charge the battery. When the battery is fully charged, the screen prompts the user to disconnect the power adapter. The notebook then continues to discharge the battery until the battery runs out.

(2) Follow the on-screen instructions

Step4: This process takes a while, wait for the battery to run out and then automatically shut down, then connect the power adapter to charge the battery, but do not turn it on. After the charging is completed (the charging indicator is off), the battery calibration process is completed.

Method 2, some notebooks, how to find in the BIOS cannot find the battery calibration option

Isn't such a notebook able to perform battery calibration? Actually, it can be operated by the "cottage version" battery calibration method. The reason why it is called "cottage" because this is not the official method, but through some manual settings, letting the books discharge in normal work until the automatic shutdown.

The necessary steps for manual battery calibration:

Step1: In the operating system (for example, Windows XP), enter the "Power Options". Select "Power On" as "Always On" and set "Off Monitor" and "Close Hard Disk" to the shortest time, and the system standby should be set to "Never".

Step2: In the "Alarms" of "Power Options", cancel all alarm options in order to completely drain the battery until it is turned off.

(1) Set power options

(2) Cancel the battery alarm function

Step3: After setting, close all applications, turn off WIFI, unplug the power adapter, and use battery power. Do not do anything until the battery is completely turned off and then automatically shut down. This process is estimated to be long and may take several hours. After the discharge is completed, connect the power adapter and fully charge the battery, and complete the battery calibration.

Precautions

After the calibration, try to increase the battery life time. If it is not obvious, you can do it again according to the above method, but it is not recommended to do it frequently. If the battery has been used for a long time, and after the battery calibration, the effect is not obvious, it may be that the life of the battery itself is naturally aging. In addition, if the battery life of the laptop is normal, battery calibration is not recommended.

At present, the main problems of Android mobile phone batteries are as follows:

The reason is that the first grid power is fast: the battery power of the mobile phone is already full to 100%, and it will fall below 90% after a while.

The second reason is that the battery power is erratic: the phone is used for a while, for example, playing a game for a while, watching a video, and then prompting that the battery is insufficient, please charge. Then I used the battery for a while and went back.

Android users who are not Root:

Step 1. In the boot state, use the original charger of the mobile phone or the brand charger (do not use the ground stall, noisy charger) to fully charge the mobile phone.

Step 2. Press and hold the power button to turn off the phone.

Step 3. Let the phone continue to charge in the off state until it is full.

Step 6. Select "WipeBatteryStats".

Step 7. Select "Yes, WipebatteryStats". It is usually completed in 1 second.

Step 8. Return to the Recovery homepage and restart the phone.

Step 9. This power calibration is completely completed. However, if there is still a problem with the phone battery, please consider replacing the battery. Normally, charging is not very thorough at the power-on state, and it cannot be fully charged, so that there is actually no loss to the battery in the long run. In particular, using a USB cable to connect to the computer to charge, the entire charging process is very slow, but the battery damage is minimal. In order to extend the life of the battery, it is recommended to use it with the charge, do not wait until the battery power drops to 20% to charge, but one or two times a month is allowed, but also good for the battery.
