[Zammer]

Well I got mine last Friday - not much time to really stress the first charge - but it lasted until today before needing its second charge. Seemed to really not get below 30% for almost a full day of my usage (subjective to my habits)

So far so good !! And I am impressed after being used to chargin at minimum once a day, sometimes twice.

And to add, the bigger case cover is just like the oem one. Same rubberized coating feel.
excellent fit and quality IMHO
