Yeah, that thing about cell phone cancer? It's a myth. An unscientific myth.
.
Here's how it works:
In the entire electromagnetic spectrum, (visible light, radio, X rays ect)
http://en.m.wikipedia.org/wiki/Electromagnetic_spectrum
it's all radiation and there's two different types. Ionizing and non-ionizing. Ionizing radiation is the kind that CAN cause cancer, it has enough energy to damage the molecular structure of your cells. Non-ionizing does NOT.
.
The point at which this transition takes place is in the Extreme Ultraviolet.
http://en.m.wikipedia.org/wiki/Ultraviolet
All energies at this point and above are ionizing, those below it are not.
.
Cell phones, wifi, television and radio are in the microwave and radiowave end of the spectrum, on the opposite end of ionizing radiation in fact. Micro/radio waves are not ionizing and do not have the energy to cause cancer.
Agreed. Always ensure that your devices have sufficient "breathing room" when in use or being charged.
You should never place them actually on your lap or directly on soft surfaces like blankets or carpet.
What if you put your laptop in the case while charging it? Even if it's off?

Charging does not overheat the battery of a laptop (if it is on a good state), but you should avoid putting it near heat sources just as prevention. Putting it on the case wont do anything bad to it, unless it'd receiving a solid solar light or some kind of heat
That's a bad idea. The heat generated by charging needs to be able to escape.
The results could be similar to the above picture, on a larger scale owing to the larger battery.

Under some circumstances, laptop lipo batteries have been known to explode, not just burn.

.
Also, never, ever use a battery that is not approved by the manufacturer. Say what you will about "overpriced markups," aftermarket batteries simply do not meet the design requirements set by the manufacturer.
.
Lastly, never put any device with a lipo battery in your check baggage when you fly. It's not just dangerous, it's also illegal now too.
That probably hapened because the battery was damaged:
Lithium batteries (assuming this is one of those) store and deliver energy making small, controled reactions of two different types of chemical components, separated by a fine non-reactive material.
That separation may be damaged by overusage, heat or physical damage, making all the chemicals inside the battery react at once and making the battery explode - and light things on fire if anything flamable is near.

Aditional info: ever heard about "not using your phone - specialy calling someone - while charging"?, well, that's why. The battery could get really hot and explode.
Not that is a common thing, nor that you should fear it, but you really should not use your phone when it's really heated up.
That was a Galaxy S4. Some phones, especially when old, doing some sort of intense processing or charging, tend to overheat. Like laptops and other computers, phones also need some ventilation to stay cool. Also, she wasn't using an approved Samsung battery, so that was just overkill.
That's not just Apple or just the charger... any aftermarket electrical/electronic device that is not manufacturer approved increases the risk of failure, fire and explosions.
Not only do they not meet the design requirements set by the manufacturer, the devices themselves were not designed to operate with them, which may lead to unwanted or erratic operation. Also universally, this will void the warranty because the manufacturer has no way of testing all of the aftermarket devices or when a failure occurs, if it was their device, the add on failing or the add on causing the failure.
.
For example with Samsung phones, using a third party battery causes you to immediately lose all near-field communication features... in order to maximize the "near" part of NFC, it's in the battery. Third party manufacturers don't/can't/won't/haven't bothered with that and as a result, you lose it, in addition to voiding your warranty.
Apparently the person's phone caught fire. Malfunction obviously of some kind. Only thing hot enough to cause that damage is the 120 from the charge cable, yeah?
