Ok, mixed news. After applying the late Feb update, battery drain seemed to resolve itself. Created the detached problem and the front camera problem when using Hello. Mar 1 update fixed those two items, but when rebooted they reappeared. Did the whole discharge and recharge deal again, and after 25 hours shutdown and unplugged battery one went to 96.4% and batt 2 stayed at 100%. Looks like we are back to the drawing board. I will fill let you know what I find out.
Same thing here. Prior to the Feb 2016 firmware update, at least my SB was able to hold charge after completely shutdown in about 60% of the time. Post Feb 2016 updates, both SB battery 1 and battery 2 drained about 5% overnight consistently 100% of the time.
The only thing I haven't tried is completely wiping the SB clean and re-install Windows. Might try that this weekend and see.
Very frustrated!
