The battery like it as a replacement battery for the Samsung Galaxy S5 very good. It is a cheap alternative to the still relatively expensive original batteries. For the life of course I can not say anything precise, but should be in a similar frame as the original, then it is worth buying anyway. The fact that this battery not NFC is compatible, bother me in any way, as I still do not use this feature. High very clear thumbs :-): So far for me
