His methodology is very flawed. Though he set the settings the same on each phone, he doesn't have each phone set up the exact same way. In order to get meaningful results, he needs to do both of these tests in a factory reset state. When each phone has been set up, and set up differently, the results aren't going to reflect an apples to apples comparison.
The 2100 wins by bit in the ultimate test. At last we laughing haha..
