I got mine around 1:30pm on Thursday, had about 45% battery, and killed it by 11pm with pretty moderate usage getting it set up, apps downloaded, texting and a couple of quick 10 min phone calls. Put it on the charger over night, and pulled it off the charger around 9:30 am, continued playing with it to finalize setting it up and learn some of the new features. Sent/received around 600 texts, about an hour and 20 minutes of talking on the phone, half of that via bluetooth. About 3 minutes of web browsing, took 6 pictures with it, did have it hooked up to my laptop to push ringtones, pictures and some app data onto it. Finally went into the orange on the battery around 3:30 am, sent a few more texts and then set it on the charger until 10am this morning. So far I have sent/received 92 texts, and talked on the phone for about an hour and 27 minutes (that was a one call phone call) and I am at 88%. So, I guess time will tell.
