While I'd believe that Verizon wants to suck as much money as possible, a 200mAh difference would get you at most another hour. Think of it this way, if a 1500mAh battery gets you 8 hours, that's about 187mAh per hour of use. So a 200 mAh difference is negligible. To double your user time, you either have to double the capacity of your battery, tweak the settings on a stock phone, or play with different kernels on a rooted one.
I just don't get all of these people who think that extra 200mAh will be the key to tremendous battery life. My phone can do almost as much as my laptop can, but with a 4800mAh battery in it I'll get at most 2 hours on battery, and that's hardly doing anything on it. I know there is a larger screen, physical hard drive and such running on it, but comparing the two that's 187mAh/ hour for the phone and 2400mAh/hour for the laptop.
The reason we have this issue is because of the i*hone. Everyone wants something as slim as that, so the android manufacturers try to produce what the people want. Everytime your read a new phone review, if it's say an 1/8" thicker than the i*hone, it's a monster or a tank. But apple isn't really on a level playing field. Their battey isn't removable, that gives them a little more space for a larger battery. Then there's lack of true multitasking and no LTE. My Inc2 usually gets around 2 full days with the stock battery and most of use coming from web browsing, phone calls, & games. That's with a 3G phone. That's why apple has been so hesitant to go to LTE. They'll get around the same battery life as the LTE androids and that's not something they want. Until the LTE radios become a lot more efficient, I doubt we'll see anything other than a 3G or hspa version from them.
