The 1620 mAh lilon battery is the culprit behind the Rezound's girth, and unlike on previous HTC devices, the ends justify the means. I'd be lying if I said that battery life on the Rezound is stellar, but it's so much of an improvement from the first generation of Verizon's LTE devices that it's hard to dislike.

You'll easily get through most of the day with a single charge, and with light use you'll make it to the nighttime hours, thanks no doubt to improved standby performance. But if you're tinkering all day at work like you shouldn't be, you're going to need to plug in before the day is up.
I'm hesistant to count this against the Rezound, as it seems the status quo with LTE devices right now, but oh how I yearn for a day when I can leave my charger at home.
