We were able to easily and consistently make it through a single day (meaning morning to evening) on a battery charge, though we chatted with a Verizon spokesman who'd been using the phone for a while and he said that he typically struggled to make it through a typical weekday without a midday fill-up. It could be that our battery was fresh and new or we just weren't beating up on the battery hard enough, but at any rate, your mileage will vary. Pure standby time was easily over three days, and we were able to get about two hours worth of consistent hotspot usage with roughly 40 percent battery drain -- in other words, in-line with what we saw while using the EVO's hotspot functionality.
