Hello, I'm glad to answer this question for you, universal charging mobile phone battery, about 5~6 hours. It will have an indicator light, when we are charging, it will have a red indicator light, will flash a way to charge, when we reach a certain amount of electricity, then a blue-green indicator light next to us will light up, when the south green indicator light.
Universal should be charged until the light turns green before it is basically full, generally 80%, and then continue to charge for 30 to 60 minutes, only the original line of the mobile phone is charged for 2 hours to be full, and the first three times the new battery is closed with the original line to charge 12 to 14 hours to activate the battery
