Tips for laptop battery maintenance:
1. Lithium battery life is directly related to the number of cycles, not the number of charges. This number of cycles refers to a charging cycle, which is simply the process of the lithium battery from full to empty, and then empty to full, which is a cycle.
2. It is best not to charge repeatedly in the range of 90% to 100%.
3. Do not over-discharge, such as always using the battery with less than 5% left, it is best to keep the battery power above 20%.
