Things to note to extend lithium battery capacity and life

1. If you use an external power supply to power your laptop for a long time, or the battery power exceeds 80%, remove the battery immediately. You don't need to fully charge the battery at ordinary times, just charge it to about 80%. Adjust the power options of the operating system and set the power alarm to more than 20%. The minimum battery power should not be less than 20% at ordinary times.
2. For small electronic devices such as mobile phones, the power cord should be disconnected immediately after charging (including the USB port for charging function). Keeping it connected will damage the battery. Charge frequently, but you don't have to fully charge the battery.
3. Whether it is a laptop or a mobile phone, be sure not to let the battery run out (automatically shut down).
4. If you are going to travel, you can fully charge the battery, but charge the electrical appliances at any time if conditions permit.
5. Use a more intelligent and power-saving operating system.
