Sony Xperia 1 V - Excellent 50% and above

So I have never been happy with tests from notebookcheck or the dxomark as they always just focus on PWM at one specific brightness. But this is never the story as usually people don’t use their phone at the brightest level or the lowest all the time. Most of the time we use our phones in the 25% -75% brightness ranges and phones do different things with the pwm and modulation at different brightness levels. So I bought myself an opple test meter and conducted the tests myself. The first phone I tested was the Xperia 1 V which has always been easiest on my eyes. Remember modulation (the difference between peak brightness and low brightness for each flicker) is just as important as the flicker rate. The lower the modulation the better. Lets take a look at Sony's modulation at different levels.

It is interesting to see Sony's wavelengths especially around the 50% and 60%. Around that brightness level on the phone you see a change from a very high level of modulation to a very low level of modulation, lower than any phone I've tested so far. This means that the device is not fully flickering off, just a slight dim, which is much much easier on the eyes then full off and on. Lets take a look at the flicker rate as well as the modulation next.

Here we see that Sony keeps pwm constant at 492hz throughout all levels of brightness but changes the depth of the modulation. It seems at 60% or higher the modulation rate starts at 24% and goes lower as brightness increases. The Sony Xperia 1 V gets a good grade in my book as long as you keep it at 60% or higher brightness. (You can use the dim function to help keep it at that level when your in a dark environment). I have been using the Sony Xperia 1 V as my main device and not had any issues with it.
