I was messing around with my phone so i deleted all the live tiles to rearrange them and before adding them again i used some apps no more resuming or loading screen and the phone got more speed and when i added some live tiles the loading screen is here again and the more live tiles u add the more you will get these screens and for more seconds you can try it guys

Makes sense, I read something on their website about how to get a longer charge out of your battery, and pinning less live tiles to Start was one suggestion. Live tiles require more processing power than regular tiles (mainly when they are updating) which explains longer resuming times.
