Confused by location of spinning circles on iphone6

I am trying to upload my entire iPhone 6 content to the icloud. When I fire up my phone there is a spinning circle to the right of the wifi symbol but in the left half of the screen. When I just turn on the screen but do not unlock it, and it is plugged in to charge, the spinning circle is now in the right half of the screen to the left of the "Battery Charge" and "Bluetooth" symbol. Is something different being indicated by the slight change in position of the spinning circle?
