I wanted to see how much current each Pi would consume under four circumstances….
- Idling in command line – low CPU load
- Starting LXDE desktop – heavy CPU load
- Watching Big Buck Bunny in HD – GPU load
- Filming Full HD video with Pi camera – GPU load + camera load
So this was done for each Pi in turn, A+, then B+, then A. I didn’t bother with the B as we had a separate B+/B comparison when B+ was launched. (I did the B rev 2 without filming the next day and updated the table.) All measurements were using a bench-supply set to a regulated 5.2V….
