Nokia 6131 Frame Rate Profile


We continue our frame rate profiles with the Nokia 6131. This is the first time we've looked at frame rates for a Nokia phone, the others have been for Sony Ericsson's w300i and w550i. Thanks to vivek at i2fly, he has provided us with some valuable information on the frame rate profile.



The same test (rotating circle) is repeated except at different frame rates. The resulting time to complete the animation is recorded, compared to the theoretical time it should be completed (based on frame rate) and the time ratio is then computed. Here are the results. Click to zoom in:





As you can see from the results, it is essentially a linear function; as frame rate increases, the time ratio also increases. Thus, there is no 'optimal' frame rate to set your animation at, but keep in mind that it is pointless to have the animation at a ridiculously high frame rate when the eye can tell the difference. Higher frame rates will eat up processing power, so it's important to maintain a balance.

In comparison, we saw from the SE w300i/550i profiles, there was a big dip in time ratio at around 45 fps which doesn't seem to be present in this phone. I'd really like to test out other SE or Nokia phones and see what they're like. If you're interested, send me an email at phirewerkz [at] gmail [dot] com.
