After my original battery from S5 slowly by holding only 1 day I bought it. Despite almost complete discharge (charging only at 10-15%), it can after 5 charges after massive. Now I have to do to get through the day, and have therefore again the original battery in it - at least brings the power over the day, so I only need to load again in the evening. So I can only advise, this rechargeable battery to buy, because it is worse than the original contained nearly a year in use!
