I noticed a drop off since the GB update. I don't use my DX heavily during the day, and don't have widgets pulling data, and at 1 pm my battery level at 60%. I took it off the dock, fully charged, this morning at 8 am.
Like some others, I had my DX plugged into a USB connected to a laptop (USB Charge only), and it wasn't even registering the USB connection, let alone the charging. When I got into my car, the USB charger worked.
Additionally, yesterday I noticed that BattStatt has not been giving accurate info. I don't know if others have experienced the same. For instance, the widget displays 80%, but when I tap the widget, it shows battery charge at 60%.
