most of aftermarket batteries for galaxy s4 are good

I think most of the aftermarket batteries are very good for the price like my last one for galaxy s4 from mpj, but the durable is the only problem. Don’t expect them to be a long term relationship, My battery lasted very well for about half year and then was on the edge of worn out. However, I actually cannot point fingers at the battery itself as I do stress my phones battery with very heavy ussage.
