You can read my post (it is above yours) to see what I think about the subject, but you
CAN'T use phone arena as a a credible source.
NEVER.
Real professional and objective websites show that the guy that you are answering to is wrong, but they also show that on tasks when the screen is ON, the iPhone is (below) but close to most of those devices, and ahead of a few.
For example, all things being equal (same nits, GPS on or off on both, etc) the iPhone has similar battery life to the Note 3 on WIFI web browsing. Ars technica confirms this too.
