I have run a powercfg /sleepstudy and the top 5 offenders are green, it states it is in connected standby for around 97% of the time but I am receiving something between 900 -1100 mW battery drain, which is around 4-5% battery loss per hour.
I performed a factory reset and did not install any applications, but the behaviour is the same. Windows documentation suggests that the drain should be nearer 150 mW or less.
Does anyone have any ideas what I can try. Technet suggests it is a hardware / driver issue, and I was wondering if there was any further diagnostics I can do or if anyone has any solutions to this?
