An interesting point to be made is that on the surface these results may seem like what we got from last year's iPhone 6s. But you also have got to remember that due to the change of the battery testing methodology, we conducted the web browsing and video playback tests back then with a screen brightness of 150nits instead of the 200nits of brightness that we use now as standard. Hence, if screen brightness levels were to be equalized, it would become apparent that the new iPhone 7 indeed offers an improvement in battery life.
