My battery is toast as well. I am getting like 2 hrs SOT before I hit 30% which is pretty bad.
I think I am going to go for the ZeroLemon one on Amazon. The Anker one has numerous reviews indicating that the battery swells on it. Total crap shoot I guess - wish there was an actual battery mfg that sold premium products. I would pay $30 for a fresh, true OEM quality battery, the RAV Power, Anker, and Zero Lemon ones are all $12! If it lasts me a year I would be surprised.
Actually, looks like the Zero Lemon one is discontinued
Looks like it is down to Anker, RAV Power, or some ****ty brand called PowerBear. Better than a knockoff Samsung that is utter garbage I suppose
