Quadrant scores are completely irrelevant, since sooo many, almost an infinite amount, of factors can determine your score.
How to test this:
-Right now, run it at least 5 times. If you get all scores to be the same, you're almost on your way to prove me wrong...
-Reboot the phone, and upon rebooting, run it 5 more times, make note.
-Open up every app on your phone, save quadrant for last, and run it again... make note of the scores.
I will guess for one, no one will have the same score at least twice, even out of the 15 tests, and I will guess two, you high and low will at lest be a difference of 200-300 points.
Post those results, I'd actually like to see those numbers for anyone willing to take the time.
What I'm trying to get at...
Rule of thumb, if the phone feels like its running slow, it's probably the placebo effect and and its not really running slow, other things around you are just faster.
You will blatantly know when your phone is feeling slow and sluggish, you can't miss it. In this case, reboot the phone, and you're good to go.
If it works, and works just fine, stop trying to fix it.
Hopes this sheds some light for you guys, don't worry about benchmarks, sure its fun to compare scores, but don't think your phone is in any way incapable because you got a "low" score.
