The usage method of mobile phone lithium battery, simply speaking, is:
1. Do not charge for too long, just charge it full. (Charging a new phone for 12 hours is wrong, that's the way to charge nickel battery, not lithium battery.)
2. Do not let the battery idle for too long. If it will be idled for a long time, pre-charge it with about 70% power.
3. Lithium battery can be charged at any time while using, or can be charged after use.
4. Do not wait until the battery is completely dead to charge, charge when the phone prompts low power.........
