Jag72- Guess we have to consider these LTE radios are like wifi left on for now when it comes to battery drain. Or the other option is to buy the bigger battery. I wonder what the big deal will be if you have to activate the LTE when you wish to surf the web and then shut it off when all you need is the phone to be on while you carry it around for the day. All my prior phones drained the battery when the wifi was left on too. Looking forward to testing again with the 1600mAh Seidio battery. The one from Verizon that has the thicker case is 2750mAh. What makes me happy is having the option to deal with this issue because I really want the speed. Now that I played with it for a day and a half, I never ever want a phone that is limited by 3G again. I don't know why they didn't name this phone Greased Lightning because it sure does work like one.
