frame drop at boot animation

Right after the "powered by android" flash screen I get a blank white screen followed by three swiping movements, on the thrid swipe before the loop there is a very obvious frame drop as the animation lags at 5-10 fps. Is my model faulty or does this has something to do with the software, did factory reset and x companion repair but to no avail. Ahh.. I almost forgot, the phone also tend to crash 2 times a month and at a very bad time a couple of time a day, sometimes it just lags but sometimes a purple noise appeared covering 2/3 of the display from the bottom before crashing.

EDIT: battery performance is ????, amazing I might say, it doesn't seem to affected by it.
