Just for fun, I charged my phone to 100% yesterday at 3pm. Used it very lightly since then (some podcast, some calls). and it just got to 20% at 11:45am today.
So for light use, the 1750 will give you 21 hrs. 100% to 20%. I could probably squeeze a few more hours until 0, but I need to have the phone working later today, so I'm gonna put it on the charger now.

Thanks!
With light use on mine (HTC everything not synching, google everything syncing) I can get about 40 hours. I would say also about 30 hours normal use. And 15-20 hours heavy use. I think my high for uptime was like 7.5-8 hours (I reset the phone ever full charge to see how its going in this aspect).
