The battery was initially very good. I will note it arrived completely dead and an overnight charge brought it up. It remained good for 6 weeks with a 45 - 50% charge at the end of day. Now it drops to 35% within 8 hours after 35 minutes of voice and a cumulative 15 minutes of data usage. I placed it on a charger with several 5 hour charge times. I want to fair and add I began to have it on a charger overnight for 8 hours. I am unable with it's current limited charge and will continue my search for a replacement. Some other units with poor service are labeled 'made in Corea', and the better ones seem to made in Japan and assembled in (red) China. The commonality of china counterfeits are rampant. I may try one more Great Offer Stock model if I can't find another alternate.

Read MoreThis is not like getter a new battery. Its like getting another old one... It doesnt even last through the day!! When you buy a new battery it should be like when you 1st get your phone. Depending on how much you use it, it should last a day and a half with a lot of use, when its brand new! wouldnt recommened this...

Read MoreThis is the perfect battery. It works way better than the one i got with the phone. I am very happy with this product. Definitely buy if you want an extra battery.
