What model is it the 13 or 15?
If you are worried download istat menu or another app to monitor your cpu temp.
Keep in mind this are very thin laptops they are going to get warm.
Usually macbooks get warm near the hinge and that is normal.
Some will disagree but I don't advice using any portable device heavily when charging.

Brand new Macs will still be building the search database, and one result can be extra heat until that task completes.
Give it a couple of days use.

You can use one of the temp utilities that you can download to monitor the sensor temps, if you want.

its the 13"... aren't we supposed to be plugging in the laptop as much as we can when using it whether its charging or not? to save battery counts?

isn't heat harmful for the laptop?

Best case scenario is charge to 100% then use it wile plugged in or unplugged.
When it hits 100% it will run off the charger and not the battery.
You can use it wile plugged in and it's charging but if it's not an emergency I would rather wait till fully charged then using it.
Try smcFanControl if not istat menu.
But if it's the bottom of the laptop it's most likely the battery charging up. In a small/thin compact decice like the 13 MBP it's easier to feel the heat.

I thought I read back then that its not good for the battery to just be asleep while charging as it can affect the memory cycle or something. but once its 100% is it safe to always leave it plugged in, whether I use it or not?

I've used the SystemPal since having to return a rMBP due to excessive heat on lap.
I use the SystemPal app a fair bit to check tempreture and fan speed.
Although best to enjoy rather than be OCD, but I'd be the same, initially, at these prices checking all the time.
If you place the nrMBP on your lap and have all programs closed except safari my 2015 tends to stay at 40 degrees C constanty - no fan - so all good on my rMBP 2015 8GB i5
I would hope the same for the new model or better (dispite thinness).

If the battery is at 100% the laptop will run off the power brick.
It's not going to affect the battery in any way.
What you must do is once in a wile run it off the battery till it hits like 25 or 30%, then charge it back up so the battery doesn't get lazy.

ok so I know its out of the topic, I just checked my battery cycle count and it has 3 already! is it normal? I mean this is brand new and sealed, and literally just arrived today.

I wouldn't read too much into that, as someone else said give it a few days but use it as a laptop off power.

I'd pop 'activity monitor' in the dock and despite what apple say go > energy - time remaining at the bottom
Safari only open.
Should be North of nine hours after settling down, hopefully 10+
If you want to close all apps while testing the FREE alfred app is very good I keep it in the menu bar, I use it daily for-
q + enter closes all apps
just google alfred to download.
I have a feeling all will be good.
cheers

Yep, it's normal. Mine had 3 cycles as well.

As far as heat goes, my 2012 cMBP gets waaaaaay hotter than my 2016 non-touchbar does. It's just my anecdotal experience of course, but this thing (the 2016 model) barely gets warm compared to what I've grown accustomed to over the past few years.

I got a similar heating issue similar to yours. Whenever i browse on safari, the bottom of my laptop heats up so much that its uncomfortable to touch. I went to the Activity Monitor and found out that there is this process called "bash" that uses up ~90% of the cpu...I forced closed it and the heating problem disappeared completely!

The only time my MBP heats up is when I game on it or do some heavy editing on it.

for those who experiencing heating try to do next to find out if your mbp has overheat problems

1. connect mbp to power adapter.

2. you'll need monitor tool for temps ( i used intel power gadget - you can download for free from official intel site https://software.intel.com/en-us/articles/intel-power-gadget-20)

3. run four times terminal with this command "yes > /dev/null"
if your cpu is i7 you need to run 8 threads (8 times with this command, so your cpu can be fully loaded)

4. run it for 5-10 minutes if CPU temps are lower then 95C your ok

share your results please to understand more issue
don't get mistake by proximity temp sensor and CPU sensor they are diffrent
