Facebook status setting problem?

[punit n]

Hey there hi,
I am using iphone 4s.
I’ve Just download Facebook application
And I am using randomly iphone and PC for Facebook.
Now facing problem telling you step by step.
I have turnoff the chat in my iphone but back to the wall its running for notifications,
But when any of my friends sign in on pc with their account, my status seems to them “I am on mobile as it should be”, (with mobile symbol right to my name)
But when they click on my offline status, my status appears automatically online to them with green symbol.
Then I also check my Facebook in my iphone, it still saws chat is off.
How to solve this problem?
Please let me know step by step.
Thank you in advance.
