Well I only had the phone running stock for about a week with WM6 offical. I then unlocked and flashed with kitchen. Now that I am getting a refurb I flashed to stock MR1 WM6.1 Verizon Offical. And battery life is MUCH better. I was at 100% untill 12:00 noon and was pushing e-mail all morning over WiFI. I was going to make a thread on this before cause the kitchen build is even worse battery than stock WM6. And stupid me even bought a new battery. But both hold a great charge with MR1. Can anyone verify this? Cause if the kitchen build has bad battery I will have to stay with MR1 even though I want my GPS
