I am a top tier "power-user" that has 2 Samsung note phones that I use constantly for calls, data and social media/ video. I have run the both of them for day on one charge without dropping below 25% on this unit before I had time to re- charge it.
Sorry, there was a problem. Please try again later.It should work fine for that I didn’t see a loss in charge even without using it multiple days in a row. Be careful with environmental hazards that can have an affect like rain, etc.,
