Personally I believe Big D5 & Palladium are both accurate to summarize this thread; possible radio inefficency & larger processor size reduce battery life significantly. I have owned just about every PPC within HTC's lineup on Alltel, Sprint & Verizon and the battey life seems reasonably justified considering hardware, coverage, personal usage, charging habits and applications requiring active downloading/updating.

I learned with my 2nd PPC to always purchase (2) extra batteries & base charger; (1) battery in the car, (1) for work and (1) in my phone and the base charger replenishes any depleted batteries over night. This maximizes battery trained life and ensures optimized battery charge/discharge.

I have been untethered to a charger for years...
