When you first charge your ZeroLemon battery, you need to continue charging for 12 hours, even though the charge reads "Full" or "100%". If you only give it a 6 hour initial charge, your battery will not be correctly charged. And you need to charge 5 or 6 full cycles at first.

I have been using my ZeroLemon 10000mAh Battery in my Note 3 for a little more than 22 months now, and still going strong !!! I am impressed with the ZeroLemon 10000mAh battery. I never need to worry about my Note 3 going dead. Unfortunately, my Note 4 has the know issue of serious battery drain. So I use my Note 3 for watching movies, YouTube, playing games. Still get at least two days on my Note 3, even though the battery is going on two years old now.
