80% of my usage is browsing the web. Why on earth would I want my i5 at 100% CPU to be able to open a website? Lol. I also edit simple documents and simple powerpoints. This is 80% of my usage. The other day while I was at the hospital (befre the NO MORE THROTTLE OR FANS thread came out) I whipped it out. It told me I had 4-5 hours left. Last night, working it harder, I had 9-10 hours! I don't think it would stay at 9-10 hours, but in 1 hour it lost 11%.... That's INCREDIBLE for my SP4! I didn't change my usage AT ALL! I streamed 45 episode from our Plex server, and then streamed the sound to the bluetooth speakers in my room! in 1 hour it lost only 11%! My on the normal plan it would have gone down a lot more. And for what? Now, with a single click, I can go back to balanced, or power saver, or my new plan called CPU DOWN haha... And with CPU DOWN my device lasts 8-9 hours vs the 5-6 it did before with my normal usage.
Bless you +Geo Hutchings! Haha.
