In my - not quite one year old - Samsung Galaxy S3 NEO nice slowly eased the battery performance. Since I came right from the beginning not all about the day (I use my cell phone quite a lot), I decided to order this stronger by almost 50% battery including its own lid, in the expectation of a noticeably better term. And my expectations were fully met! With the same user behavior, I am now quite comfortable in a whole day on a single charge. And that innately very lean S3 is even a bit better in the hand.
One tip, if the supplied battery cover does not close: Apparently the old Galaxy S3 and Galaxy S3 NEO a different layout for the location of MicroSD and SIM card. The cover was made for the old Galaxy S3; the Galaxy S3 NEO "spread" a small increase in the battery cover where the old S3 are the slots located (if you look closely, you know what I mean). This increase in the cover can be easily removed with a sharp knife or sharp scissors. The lid also sits on the S3 NEO absolutely perfect.
