Default Is it normal for my Samsung Galaxy S3 to overheat on a charger

I don't know if I should complain to T-Mobile or not that
my new Samsung Galaxy S3 gets so hot sometimes when I charge
it on the car charger that it has to shut down due to
battery temperature overheating.

Is this normal for your Samsung Galaxy SIII?

Mmm, not a "Samsung Galaxy SIII", and not "so hot ... it has to shut down",
but the batteries in *most* of my cell phones do warm up perceptibly as
they get themselves charged. HTH. Cheers, -- tlvp

My S3 gets slightly warm when its charging, but not so hot that it has
to shut down.

I wonder if you're using the wrong kind of car charger or something.
Is it only when charging from a car socket that you get this problem?
What about on a normal mains powered charger?

I generally charge the Samsung Galaxy S3 at home using a USB adapter
plugged into a 120Volt wall receptacle and in the car using a USB
cigarette lighter adapter plugged into the cigarette lighter socket.

I've switched cables, and the problem does not appear to be cable
specific.

As you implied, I only notice on the battery overheating the road;
but ... that's also when I'm using GPS and Bluetooth; at home, I
generally have Bluetooth & GPS turned off yet I have Wi-Fi turned on.

So, to make an apples-to-apples test, since I'm at home right now,
I just turned on the Wi-Fi, Bluetooth, and GPS - and - I'll report
back if/when it gets hot at home.

But, otherwise, my answer to you is "yes". It does only happen when
I'm on the car charger.

If that remains the case, what does that tell us?

The amount of warmth generated by my S3 during charging, whether in the
house or in the car, is almost imperceptible. I can only feel it if I
tightly sandwich the phone between both of my hands and squeeze.

Do you have a memory card installed? I've heard stories of that causing
additional heat and severe battery drain in rare cases, but I'm not sure if
that's what you're seeing.

I've been testing the Samsung Galaxy S3 for the past few days:
Info: Charging Paused. Battery Temperature Too High

It only happens on the one car charger I have (either slot):

We're not talking warm; we're talking almost burn-your-skin hot.
No memory card installed; and it doesn't happen on a wall wart or
connected to the USB of a PC or Mac (tested it at the library).

Clearly it's the way the phone interacts with the car charger; but,
what would be different about that power supply that would make a
battery get hot?

If it matters, an iPhone connected to the same charger works
fine, as do Motorola Bluetooth devices such as a remote speaker
and a Motorola earbud.

Could you try using a different charger on a different vehicle just to
rule out the possibility it could be a fault with either the charger
itself or something to do with the socket in the car.

If that doesn't change anything could you borrow someone else's S3 and
see if that gets hot too when charging off your car.

You basically need to eliminate one thing at a time to identify where
the problem lies. Easier said than done, I know.

I'd get out my trusty voltmeter and check whether, just perhaps, that "one
car charger" you have is putting out a full automotive 14V or so, rather
than the 5V a USB-powered device expects to be charging from. Such an
overvoltage condition could well occasion the overheating you're seeing.

HTH. Cheers, -- tlvp

This is in line with my suspicions too. These cigarette lighter
to USB power adaptors are generic and cheap - try another one.
