This is a common problem with many applications, even just applications built using WPF.

http://arstechnica.com/gadgets/2014/07/why-google-took-years-to-address-a-battery-draining-bug-in-chrome/ is an interesting read.

Basically Google was aware of this since Chrome's release, because they wanted the browser to have better performance or something. So it wasn't a bug, it's a feature!

I had to try this one out for myself. I got two versions of completely identical laptops, and then ran with it. Both laptop version were taken back to the conditions they were built at, all unneeded software removed. They were also battery swapped, to compensate for any differences there might be between batteries.

The two versions of laptops that were used; again restating that they were brought to identical mirrored copies of each other...

2x entry level models of HP laptops with I3's.
2x higher end performance models of Alienware's with I7's.

In the entry level HP's I documented an over 27% reduction in battery life when running Chrome, than running two other internet search engines.

On the Alienware's, I documented a just over 20% battery life difference.

Not sure why Google has not internally addressed this one over so much of a time scale. Also surprised it has never been addressed by some external group of people, especially at one of the many Google events??

Instead of percentages, it would be better to tell us time. For all I know, 20% could mean one hour or 10 minutes.

The percentage relates to the knowen or expected time the battery is stated to last for. For example, if the battery says 5hr usage, minus twenty percent from 5hrs.
