i'm not trying to flame, but getting that type of run time on one charge means you basically haven't used the phone since it's been off the charger, imo. if your display time is an hour or more i just don't see how it's possible to get past 24 hrs (much less 40) with 30% battery left especially once you add in calls totaling 15 mins or longer, wifi, mobile data, push, pop polling, etc. like i said, keeping wifi on helps, but i don't see it helping that much.
for those of you getting more than 24 hrs with 30% battery left i'd be really interested to know what your display time is and phone calls made and what battery you're using.
for example i have the 1750 battery and i use my phone what i think is fairly normal as it's my only mobile device that i use for work and personal. my display time is usually close to 2 hrs, calls totaling around 10-15 mins, wifi on most of time, mobile data, activesync push, one pop3 at 5 min intervals, occasional bluetooth. my phone is off the charger starting around 7am and doesn't get back on until around 11:30pm. by the end of day i have about 25-30% battery left if lucky and been around a strong signal all day. with the 1300 battery i would make it to about 9pm and the phone would be telling me to charge up.
i haven't tried the 1500 battery so i have no clue what type of battery life it can put out, but i don't expect that it will be better than the 1750 battery. this is another reason why it will be interesting to see the results from dustinf00.
