do not over charge battery for whole night.kindly charge battery for 4 to 5 hours before first use with swithing off mobile.back up time of battery is depend of usage of internet and video playing.it is always better to buy sharbros brand instead of on the name of big brands.
Battery is very very bad quality. Within 1 hour charge finish & phone getting shut down. Battery is not fit into the cell, it is smaller & it is moving inside the cell whenever I move the phone. So that suddenly phone shut down due to disconnect. I didn't want to give one 🌟 also.
