FAQ

Q1. How can I tell when my ZeroLemon cell phone battery is fully charged?

We recommend that you leave your phone plugged in for an additional half an hour after it displays as “fully charged”. Many phones display 100% charge when they are actually only at 90%. The extra half an hour of charge time helps alleviate this issue, and ensures your battery is at full capacity.

Q2. How can I know if an ZeroLemon cell phone is compatible with my phone or not?

We offer detailed model descriptions, and lists of compatible phones/devices, on every website on which our products are sold. We highly recommend that you carefully check this information before ordering any of our products.
