Same type of thing happens with computers though, you keep them on for a really long time and they start to run slow, so your restart it and caches are cleared, the ram is refresed, it closes out of those old background processes you did use awhile ago but now haven't for awhile. Lots of things add to it and it'll happen with a lot of Android devices. Just keep on top of your Task Manager and remember to turn off your phone every once in awhile.
