It seems to me that my battery life is much better since the update. However, I've had the phone for just a few days less than a month and perhaps I'm not using it as much and consequently the battery time between charges seems better when in reality it's more because of less use? Anyway, for what it's worth, I'm at 1d,8h,29m on battery with no short term time on a charger with Battery level currently showing as 50%. I am in a strong 4G LTE area and it's on all the time along with my Bluetooth headset. Still I think it's very hard to compare time on battery between users.
