    The result will be about 50% more effective battery life for the cdma Pro over the cdma 800w. You would be for example charging 575 mAh battery in an 800W more than twice as often as an 1150.

    In terms of why the treo pro has a 1500 battery the answer is a simple "lessons learned." As has been mentioned even though a cdma versionm of the pro is likly to come in much less than a year, the development cycles between the tow is probably more than a year.

    To quote our esteemed leader, "The math doesn't work!"

    1150 / 1500 = .76667

    The Centro/800w battery has 76.7% the capacity of the Treo Pro battery.

    Or, inverted, the Treo Pro battery is 130.4% the capacity of the Centro/800w battery. So where are you getting this 50% figure? And no matter how many times I read it, I can't make any sense out of "You would be for example charging 575 mAh battery in an 800W more than twice as often as an 1150." What does that mean?

    Because a 575 MaH battery would give you less than half the usable time of a 1150. Users would be recharing a 575 not twice as often as an 1150 but close to three times as often.

    That is why a 1500 will give you around 50% more usable time than an 1150.

    This isn't even to mention a 1150 will degrade faster over time than a 1500.

    But his application of the math is incorrect. Battery draw is not linear. Voltage drops as well. Also users who would charge at 200 mA remaining on either battery would be have 50% more use time even linear.

    Ask yourself why a 2000 mA batteries in a camera give you about three times the number of pictures as 1000 mA batteries.

    Simple logic. Good job.
