My customer has a mixed estate of WM5.0 MC9090's that have the different display types and have told me that the newer displays are using more power than the old ones, and that when the battery reaches 20% the phone is turned off. They turn the phone on and the units continue to finish the full working shift. I know that in WM6.1 we have the 3 Run Time options, but is there a registry key that we can use to lower this threshold for WM5? Thanks in advance Justin
