iPhone coroutine different Than Editor

Whit coroutine yield in WaitForSeconds editor is different than iphone .

I have this problem in the 2 Mac macbook and imac .

The oddity is that if I show the dock , the editor
increases the time but not like the iPhone, iPhone is faster.

Why?

anyone have my problem ?

it’s a bug ?

The editor may sometimes not behave exactly the same as the device. How much time difference is there with this?

l IPhONE is faster double or more than the editor
