First, some pictures:
Phone with extended back cover, compared with TPU case:
Front and back of phone, with extended battery cover on. The cover is quite solid and fits flush with the phone. The build quality is very good, quite similar to the stock back cover IMO.
As far as the performance goes, I'm pretty happy so far. After I got it, I charged it completely, and then started using it. Here is my usage graph so far. I accidentally left TuneIn Radio running in the background overnight, hence the big "awake" section. Even after 16 hours of some decently heavy use, I've still got 34% left. And this is on the very first charge, before any calibration has been done. The stock battery definitely could not last through this much use on one charge.
