The point is that they're advertising this phone with 48-hours of "Use Time" which to me means that I should be able to go an entire day of moderate on and off without running low on battery. The reality I'm finding is that the phone will nearly die during the period of 7am to 10pm, and all I'm doing is some texting, Facebook, and internet browsing. The fact that I could charge it during the day at my desk is irrelevant - for $624 and a 3760 mAh battery, I want better longevity than I get with my 2-year old Moto X and it's 2200 mAh battery.
