Apple Event: May 7th at 7 am PT
I am using new mac book pro 15 retina display. I feel the machine is very hot while charging.. the plug area and top side of functions keys are very hot. is it a problem?
Also i need adivce about the battery usage .. now i am using the machine 10 hours minimum a day and full time its plugged inn .. is it the right way or need to use battery when its fully charged?

The power area does tend to warm up, but it's nothing to worry about.
I use my MacBook Pro plugged in at least 90% of the time. Every two weeks, I've a reminder set to remind me to take the machine off mains and let the battery drain down to 30-40%. This keeps the ions moving and the battery happy.
If you're going to run off your power adapter most of the time, just remember to run on battery about twice a month. This will keep your battery in fine shape.

The way you are using it is probably typical. Not a problem.
It is normal for the area around the power adapter to be warm while charging it. Heat is dissipated throughout the entire case, which is a reason not to use aftermarket cases or "skins". If it is so hot you think you would burn yourself though, have it checked out by Apple.
Be sure to run the battery down at least once a month to maximize its longevity.
Thanks for the replys .. I believe its nothing to worry and use power connected always and once in a month or twice darin down the battery.
I am not using any case covering n all .. the machine is naked as it is and also sitting in an air conditioned room
The heat in plug area we cannot keep fingers there more than 5 seconds.

Just make sure the contacts on the plug and the pads on the jack are perfectly clean and both mate perfectly flat with no debris to impede it. That takes care of the plug area. See (especially points #7 & 8): http://support.apple.com/kb/TS1713
As for what "very hot" amounts to, you do realize it is a relative term? If it sets your mind at ease, get a utility that can read and display the values from the myriad temp. sensors stuffed on your Mac. If any goes over 100C, then worry. I recommend Marcel Bresink's Temperature Monitor, free: http://www.bresink.de/osx/TemperatureMonitor.html
Edit: if the plug area gets as hot as you state, that is NOT normal. Take it and the power brick to an Apple Store for assessment before it burns out.
One more thing i noticed is . When pluginn the heat is over (On orange light) once its green the temperature is coming down.
As i am using the machine a day more than 10 hours is it good plugged power always ??

That's fine - mine's plugged in 24/7 except for those bi-monthly 'breaks' when I run on battery...

Thanks. Clinton

When orange, it is fast-charging the battery, during which time there can be up to 85W / 16V ≈ 5A of current going thru the connector. When green it is in topping off or float charge mode, with much reduced current. Given the heat you describe, either the pins and pads between the plug and jack are dirty or not making good solid contact, or something else is circling the drain.
This is a brand new machine and it is 200% clean. now it is green light and not much heat.
