>Really? On my Android phone, the CPU is about the least power-hungry part. By a huge margin, the power-hog is the screen's backlight.

Yes exactly. This is a wellknown fact. If you have an AMOLED (variant) screen, everything light/white consumes a lot of power. Black nothing.

>BTW, have you ever noticed that web-access on a 3G phone is sometimes really, really, really slow (20 seconds + for a google query, yet simultaneously quite quick for a large webpage load)? This is buffer bloat in action.

Interesting. I have the same observation, and always thought of it as "the mobile web has huge latency but quite good bandwidth".
