iPad 3 overheating...the culprits

Some iPad 3 users have reportedly complained that the device may get uncomfortably "warm" especially when playing 3D games or using it in the sun. The device will then turn off as a protection feature so as not to damage the silicon inside.


Let it be known that it is quite common for something to get warm in the sun (quite obvious we must say) especially an electronic. However, we set out to figure what else could cook your hands while having fun with your iPad.


Convict 1: The 4G chip


This is not a big offender for overheating (probably get 1 month for it). However, great speeds come with great power consumption, great power consumption equals great heat emission. Its not that much of heat emission but it contributes to the heat build up.

The Qualcomm 4G/3G transceiver (orange) and Toshiba MCP-Master Control Program (yellow) are the main perpetrators here.


Convict 2: The Display


Remember when Sharp said that they could't supply the iPad 3 display because of the illumination needed to light up the screen? The new screen has 72 LEDs, twice the iPad 2's. This may consume a lot of juice, giving up more heat in return.
oooooh, smoooth


Convict 3 : A5X


What happens when you cram a couple of ICs in a small box and ramp up the amount of graphics they churn every second? Yes, more power requirement, more heat output. 
A5X in all its glory


Main Perpetrator : The Battery


If you draw lots of power from a lithium-ion battery (any), you gonna have some heat coming off it that you can fry an egg on. In this case, we have a 42.5 watt hour Lithium-polymer battery generating and insulating the heat produced by all the above mentioned. It gets 10 years...and probation.
