Win8 Thinkpad X200s battery life

[Monocat]

Hi all,

anybody notices shorter battery life in Windows 8 compared to Windows 7?

on my x200s, the battery life is averagind 4,5 hours of normal use, in Windows 7 it was definitelly much higher.

Are the drivers to blame?

Yes, I am only getting under 4.5 hours battery life on my X220 (only a few weeks old) with Windows 8.

I cannot remember exactly how much I was getting with Windows 7, but I think it was well above 6 hours.

I installed Windows 8 Pro fresh and I'm using the Win7 versions of Power Manager (but the Win8 power drivers from System update), Access Connections, Communications Utility and Hotkey drivers.

well, this is strange, Microsoft promised longer battery life for Windows 8.
Well..
