Unfortunately, Windows 7 is still a resource hungry machine, slightly better than Vista but not as efficient as Windows XP. One of the feature in Windows 7 and Vista that is hogging all of the battery juice is the AeroGlass feature.

Aerofoil extends Vista and Windows 7 notebook battery life by:
- Allowing you to manually disable Aero Glass.
- Optionally managing Aero Glass user interface.
- Optionally managing sound muting (NEW!).
- Optionally managing Windows Sidebar.
- Optionally showing a quick hibernate button
One of the smart feature found in Aerofoil is the auto mode where it will automatically turn off the Windows Aero Glass feature and switch to other low battery usage settings. Aerofoil is a free download, open source, and works with Windows 7 and Vista only (Windows XP don’t come with Aero Glass feature).
p.s. Unless you have a really fast computer, the best option is to use the classic theme, simple, easy and fast.

Aero actually has no significant effect on battery life. In fact, it might actually increase it — that’s if you have a compatible GPU.
With Aero, most of the UI rendering will be hardware accelerated — something GPU’s are much more efficient at processing. Without Aero the main processor would be left to render everything; and since it’s not as efficient at graphics processing, it will use more power.
My advice is not to use this tool.
Are you sure, turning of Aero can save your battery life? Is this the only factor which saves battery time?
