It is not necessary to fully charge lithium batteries before disconnecting them. Just charge whenever you want, try to keep it charged, avoid overheating and don't overcharge, that's it.
In summary, don’t let your “lithium” battery discharge! It is the best protection. Plugging in charging cables and transmission cables at any time will not affect the battery. The characteristics of lithium batteries determine that they have almost no memory effect, so even if you have 80% of the power you can charge. without fear. Once the battery is fully charged, it will automatically stop charging, so your battery will not be overcharged and have no impact on the battery!
Qualified cell phone lithium batteries generally have the following characteristics:
Protection againstovercharges: automatically stops charging when the battery is full (but taking into account heat and safety, etc. For other reasons, it is not recommended to play with the phone while charging, especially when the phone is very hot) .
Over-discharge protection: The battery stops discharging when charging (it is directly powered by the charger when charging, so playing with the phone while charging will slow down the charging speed, but not will not affect battery life).
Short circuit protection: automatic disconnection when the battery is short circuited.
The lithium battery of mobile phones has no memory function and can be charged at any time.
Characteristics of lithium batteries:
1. Excessive charging and discharging will cause the service life to decrease.
The definition ofcharge and discharge: charge the battery once it is exhausted.
2. Charging at any time will not shorten the lifespan.
3. When the external ambient temperature is low, the amount of electricity stored in the battery decreases.
