If you managed to snag a new HTC Trophy on Verizon, you may at times feel a little underwhelmed by the 1300 mAh battery on board (most WP7 devices sport around 1500 mAh). If that's the case, remember to pick up an OEM extended battery via Verizon's accessories.
The extended battery is a plump 2150 mAh, which should work even for the biggest users out there. Of course, it does feature an extended "hump" door but it doesn't seem too large for those who need the juice. The big juicer goes for a fair $49.99 + tax.
It's nice to have options!
