Just a quick follow up on my side.
It's been about 3 months (already) with these new batteries I got from eBay, and I have to say that all is still going well with the one I'm using, Dr. Battery is still showing the Health as 100% (1218 mAh).
With data only turned on if and when needed, my phone can easily last the day, even 2, possibly 3 but I tend to put it on my Touchstone whenever I see the battery icon showing anything but full as a reflex as I never know when I'd need to be away from a power source.
But lots of times, I simply leave it on my desk at night and if in the morning it's showing to be a bit low I pop it on the touchstone until I leave for work, most times, it's enough to top it to 100%.
I've always been amazed on how fast the Touchstone charges all the Pres I've had (original, 2 and 3). The kids with their other phones, plugged in with cable, always seem to take a lot longer for them to get fully charged, and always seem to die a lot faster.
