This is just a seat of the pants review. So far, about 10 hours in and i am loving it. I am not posting percentages or numbers, just my overall impression. I charged it with the phone off for a couple of hours and have been using it all day. And it goes to say, that the battery will perform at its best after 5-6 charges. Fit is great, no issues there. And please, no posting the stale, same old reference to any web site claims, its been done to death. life with this 1750 seidio is going great so far.
