I received my item and charged them in my phone...they worked for 24 hours and then I got a dead battery warning on my phone. I bought two and it happened with both of them. I could kind of understand if it was only one of them, but the fact that it happened with both batteries on different phones leads me to believe that this seller is deliberately selling faulty batteries. This is a scam...don't buy.
