Does Aero Glass really reduce battery life?

Does Aero Glass really reduce battery life? I have heard some people say Aero glass reduces battery life and some people say its a myth and it does not.

Well this is under "Real World News" - "It's a conspiracy!". I'd say it should be under Microsoft (Windows) Discussion & Support :).

 

And to answer your question, I think that when laptop graphics cards were crappier, it took more gpu power to run DWM, now I don't think it's an issue.

Hello,

Yes, there is a definite answer. There is no conspiracy.

That still isn't truly definitive, because there is no consistent data in the article. I have read from other experts that aero glass doesn't affect battery life

I would say with certainty, No.

blogs.windows.com is the official Windows team blog.

There are no "other experts" except the experts that made Windows themselves...

As I suspected, the battery consumption for the non-Aero scenario was within 1-2% of the consumption with Aero enabled. In other words, disabling Aero had little or no measurable impact on battery consumption under Windows Vista Ultimate when running a mix of common business productivity (Internet Explorer, Word, Excel and PowerPoint) applications.

There is a definitive answer. Charge the battery to full and run the machine with Aero Glass on till it runs dry, measure this time. Do the same with glass turned off. That's your definitive answer. A conspiracy it is not.

Thanks for all the answers, but I will have to test to see if aero glass really reduces my battery for my self :)

I'd say the most definitive way is to look at a power meter with it enabled and disabled (~$20-30 to purchase). I would suspect that the difference is less than watt. Then just do a ratio of how much the difference is over the total energy being expended to get the % difference in power usage. A difference MAY not even be detectable.

 

I'd test myself but I don't run Windows 7 anymore.

 

You'd probably need to remove the battery or have it fully charged to get a correct reading with such a device because laptops pull more energy when charging the battery.

That's the best plan. You'll never know (or trust any other answers) until you try yourself.

Honestly, since everything is hardware accelerated with glass off (but Aero still on) anyway, the glass itself is just one more pixel shader in the pipeline. It'd be a negligible amount of power.

As far as I know Aero doesn't reduce battery life compared to classic or basic. Aero without transparency might even save some battery. All GPU's can run Aero (even with transparency) in idle speeds. You're actually offloading the CPU a little since the GPU takes over some of the work it's better at.

I have always used Aero Glass, and my laptop batteries have lasted a pretty long time.

^ This is what I imagine also.

I have used Aero glass for quite a long time and I have had very good battery life.  I agree there is little discernible difference between non-aero glass and aero glass.

Hello,

The Windows team (the link I posted) gives you the answer. What is there to test?
