## Description

[About the use of compatible batteries] 1. Depending on the usage environment, the remaining battery capacity is displayed differently. 2. To charge the battery, it is recommended to use the original charger or charge the phone body. 3. The new battery can be charged and discharged 350-500 times in the normal cycle. Regardless of the original or compatible battery, battery life shortens over time. 4. If you save the battery for a long time, please make sure the power supply is not 0, otherwise the life of the lithium battery may be shortened. 5. Do not store it in a place with high temperature (in the car, in a place where the sun shines etc.). 6. If the lithium battery has a charge rate of approx. 60% (approx. 3.7 to 3.75 V), it can be used for a longer period of time. 7. Charge and discharge three times before the new battery: please go off empty, turn off the battery for 4-6 hours, turn it on again and run 3 times to activate the battery use time.
