8 reasons for the loss of laptop batteries

1. The battery itself is of poor quality
2. Use low-quality chargers
3. Long time operation in high temperature or low-temperature environment
4. The battery is connected to high-load peripherals, and the plugging is not standardized.
5. Excessive charging and discharging (the remaining power of the battery is less than 3%). The circuits are protected, but it happens occasionally.
6. Incomplete charging and discharging (not to recharge after using up, but to use and recharge if you want)
7. Long-term use of the battery in strong electromagnetic radiation (will interfere with the conductivity of the metal in the battery)
8. Long-term use of batteries in humid conditions (wet batteries will reduce performance)

For Windows 8 and above, you can enter powercfg /BatteryReport in the command prompt to view battery usage and consumption, or you can use hardware detection software (such as Everest) to see, and sometimes false alarms.
