Purchase Notes:
1. Please carefully check your product model to avoid purchasing an incompatible product that cannot be used
2. Please use a charger that is compatible with the battery or the original charger provided with the phone to extend the battery's lifespan
3. When using the battery for the first time, please fully discharge it. Charge it to 100%, then continue charging for at least 2 hours. Use the device until it automatically shuts down due to low battery. Finally, charge it to 100% again. A new lithium-polymer battery will achieve optimal performance and lifespan after completing 2 to 3 full charge-discharge cycles

Battery Q&A:
1. If the new battery cannot power the phone, clean the battery connector with sandpaper or a stiff brush to remove any oxidation; Check if other flexible cables on the motherboard are properly connected
2. Charge the battery using the original adapter charger for 30 minutes. If the phone shows no charging signs, try using another Android adapter charger
3. If the battery level remains low after installation, it is because some phones require a system reinstallation after battery replacement to allow the system to recognize the new battery cell and display the correct battery level
