Model : HB 356687ECW Model Name: nova 3i Compatible Devices: Nova 2i 2 Nova2i Nova2 Plus Honor 7X P30 Lite Battery Cell Composition: Lithium Ion Original Equipment Manufacturer (High Quality Battery capacity) IMPORTANT: Please remember that a new Lithium-Ion battery's full performance and longevity is only achieved after 2 to 3 complete charge and discharge cycles. After you go through 2 to 3 cycles, you'll never have to condition your battery again! All talk and standby times are approximate, depending upon carrier's network settings, signal strength, and features selected. All of our batteries have highest level of security protections. Including, over charging protection, overheating protection, over load protection, short circuit protection, highly effective temperature control. TIPS TO GET THE BEST EXTENDED BATTERY PERFORMANCE: Turn your device off from time to time. Many smartphone users keep their phones on for days and even weeks at time. Every day, or couple days it is smart to turn your phone off if even just for a couple of minutes. That gives it a chance to refresh itself, clear it's running tasks and memory cache, and make it happy again and again. BATTERY CHARGING TIPS: If you are going to be charging your device all night long, make sure it is placed in a well-ventilated area. Make sure you are using a compatible charger. Incompatible chargers are one of the leading causes of malfunction. You should charge your cell phone battery when it gets to around 20% instead of 0% if possible. Letting a battery fully discharge all the way to 0% all of the time is not healthy for the Lithium Ion Cells.
