45% with moderate usage and maybe 20 minutes of Pandora. I did some quick math and when I was hardly using the Pre I was getting 4.2% per hour of usage.
I haven't decided yet if I will keep this nice phone, but if I do, I'll be getting a touchstone plus a Seidio extended battery. I feel like I won't even need to pay attention to the battery anymore. How hard is it to set it on the touchstone while not using it at home/work? It's a brilliant thing.
I am at 50% exactly and it has been off the charger for 8.25 hours. This includes showing it off to some coworkers, a few minutes of Pandora, push e-mail, frequest Facebook checks, and text messaging.
20% - I have been showing off, opening/closing apps, pandora streaming almost an hour, no phone calls, texting, setting up my profiles, editing contacts...so a full day of good workin onthe phone. It's now on the charger at my desk :-)
The APP that IMO drains the phone quickest is the AIM or Google talk app. I would recommend that people shut it off when not in use...makes a huge difference
Its 1:18pm here, and my battery is at 48%. Moderate usage, I would say, mainly e-mail with a little web browsing, app catalog browsing (checking for new apps!), sms and gtalk.
