How to calibrate laptop battery on Windows?
The battery capacity display is not displayed on time, because long-term plug-in or light charging and discharging of lithium batteries will lead to system identification deviation. Calibration allows the system to re-learn the actual battery capacity through complete charging and discharging. The specific steps are: 1. Fully charge and do not use the computer when charging; 2. Unplug the power supply and discharge it naturally until it is automatically shut down; 3. Leave it for a few hours or overnight after shutdown to cool down; 4. Fully charge again to complete the calibration. In addition, you can also use the command prompt to enter powercfg/batteryreport to generate a battery report for "soft calibration" to view the values of DesignedCapacity and FullChargeCapacity to determine the battery status. It should be noted that some models have discharge protection mechanisms, and priority should be given when the battery ages or expands.
