How to use a ZeroLemon battery case to charge your phone



The main function of a battery case is to charge your phone up. 


Before charging, you will need to hold its power button on the battery case back for 3 seconds or click it once (for some old products), to turn on the battery case first. Then you'll see its LED lights are on and your phone starts charging.


Most of our battery cases support data sync, you just need to plug into a data cable without removing the battery case.


For issues with other functions, you can contact us directly.




How to recharge a ZeroLemon battery case 



1. When the first LED bar (near the power button) blinks, which means the battery case power is lower than 20%, please use the factory OEM cable (or the one provided with your phone) to recharge the battery case. The first bar would start blinking, and then one by one.


Please unplug the battery case when all 4 LED lights stop blinking.

2. To optimize the battery life, when you receive the battery case at first, please drain it to empty before the next recharge ( for the first 3-4 charge circles when you start using the battery case). After that, please recharge it before it deads completely.

3. You can charge the battery case with or without the phone; While charging both the case and your phone, the phone will go charge first then the battery next.

1. How long it needs to fully charge the battery case alone?


  • For 5000 mAh capacity - around 2.5 hours
  • For 8000 mAh capacity - around 4 hours 
  • For 10,000mAh capacity - 4 to 5 hours 


   If you charge it with the phone together, extra 2 hours would be necessary.



2. Recharge the battery regularly like once every month


 It applies to the situation that you do not often use the battery. When you don't need the battery case as daily power support and keep it in a box, please charge the battery once every month at least.

 

 If you use a ZeroLemon battery case frequently, you can charge it when it is at a low power level.
