I've been using the HTC Express 1700's for about a month with no trouble, I have no hard data to back me up, but they do actually seem to have at least a little more capacity than stock. The important thing though is just to have an extra or two!
That's been my experience too, and not just with cheap batteries but also with the more expensive Seidio batteries as well.I'd be interested to know how they last in say 4-6 months, that's the real test, because i noticed that cheap batteries seem to do okay at first, and then start to lose capacity as time goes on faster than oem, though that could just be my bad luck.
