To be honest, I actually just received it today and only been using it for 2 hours. It came with a little over 50% charge, no complaints from that. I think twice as thick is an understatement and its also much heavier. Leaves quite the imprint in my pocket. But, on the good side, it feels much better in my hands in all positions. Its grippier too. First thing I did was download the best performance profile for KT tweaker I plan on running 100% of the time. Battery life is definitely improved. Soft keys are much easier to press as well.
If you decide to purchase one, take note to remove the battery from the case, insert the battery into the phone, and then put the case on. It comes assembled, the battery in the case, just separate the two first. Any questions, feel free to ask!!
