sounds like a bad phone :S i dont have slow down anytime on my phone on WM side, android is another story since it wasn't designed for it.

or at least the slow part for me is just the processing power of it, which means it never runs faster than it can but it runs at the same speed all the time too

The zoom bar is a sticker or something that lets you know where to rub your finger across so it should always show even when phone is completely off with no battery in it.

try doing a clean "stock" flash for the phone? could be the phone is on a bad rom
