Hi All, Last night, I changed my batteries at 10:00 PM. They had depleted fairly quickly. I read a .brf file for a couple of hours and my battery level remained at 100 percent. I checked the battery level at 8:00 AM this morning still 100 percent. When I just updated to beta 22 at 9:50 AM, the battery level was at 96 percent and is still there. So, my batteries did not drain overnight with beta 21. We will see how it goes with beta 22. Robert Carter
