No. Otherwise Nexus 6Ps, 5x, HTC, etc. would be having the same explosion issue.
Not necessarily. This still could be an issue related specifically to Samsung's manufacturing process.
After all, everyone else uses lithium batteries too, and yet...
Then it would be an issue with Samsung and their implementation of USB-C.
I thought the OP was asking about it just being USB-C in general and that is why I wrote that answer. .

This was exactly my point, Samsung in moving towards USB-C had to implement a new charging system. In doing so, they obviously had errors along the way either in design, build and new battery charging software.
How many global tales of Nexus 6p or Nexus 5x phones exploding or catching fire have there been? Nil. Both came out in 4th quarter 2015, and both were the first mainstream phones that had USB-C.
Other flagships that have had no issue with their USB-C: HTC 10, LG 5, OnePlus, and a variety of other Chinese Android sets...
Waterproof=limited airflow. Edge screen, s-pen... Even less room for ventilation. A ton of features and technology packed into the thinnest possible case with quick charging. All of this seems far more likely that a charging cable type.
Here's something interesting;
"However, a little digging through a ChipWorks teardown reveals the use of a Dialog DA9155 charging chip, alongside the familiar MAXIM power IC. Importantly, this DA9155 does not appear to be found inside the Galaxy S7 or S7 edge. This chip is a slave charger that extends the current capabilities of a master power IC for increased charging currents up to an additional 2500mA. It’s controlled by the application processor (AP) and, interestingly, kicks in during the high-power constant current charging stage.
A read through the datasheet reveals that this chip features an AP programmable output current, switching frequency, and temperature monitor. As a slave device, programming and controlling the current and cooling is all left to the AP, which Samsung would have to program itself.
Careful consideration has to be made not to exceed the battery’s charging current, optimize the switching frequency to the inductor charging circuitry for efficient power transfer, and monitoring the temperature of the battery. Furthermore, the DA9155M doesn’t force a chip reset until TJUNC_CRIT is triggered at 140°C, so it’s up to the AP and Samsung’s programmers to monitor lower temperatures and adjust power delivery."
Obviously, we don't know if it's the cause or a contributing factor, but it's something else to know.
Source: What caused the great Galaxy Note 7 defect and recall?
Possibly.How does this explain units that caught fire on standby or off..... Battery fatigue?
Given how many phones already exist with USB-C, I'd say that if USB-C were the cause of problems on the N7..Samsung needs to fire whoever builds the charger portion of the phone.
