From time to time, the reports about exploding smartphones appear in the network. However, it does not look in this way that only a single manufacture has this issue. I remember several reports about Sony, Xiaomi and even iPhone smartphones. However, the latest iPhone explosion was caused by physical damage (bicycle accident) of the battery. This time, this very unpleasant failure happened to owner of the exemplary flagship smartphone, i.e. Nexus 6P.
The Nexus 6P was manufactured by Huawei, but this is generally Google product. This is also the most advanced flagship smartphone with Qualcomm Snapdragon 820 chipset. It supports Qualcomm Quick Charge 3.0 technology and uses USB Type_C reversible interface for charging and data transmission.
Nexus 6P owner was using the original charger and USB type C cable.
We all know that modern smartphones are very hot when we are using them (e.g. gaming) and charging at the same time. However, as it was reported by the Reddit user, the smartphone was charging in the ‘sleep mode’ (very low screen brightness and do not disturb mode enabled) when Nexus 6P exploded at 3 AM. I bet that it was very frightening wake up.
There was also reports that it is not safe to use USB Type-C interface and Quick Charge technology.
However, new USB interface was also designed in order to carry voltage higher than 5V for charging purposes. Also, the charger and smartphone itself are very inteligent devices, therefore charging voltage and current are controlled by special circuits. Google Canadian department has reacted very quickly and the damaged smartphone is investigated. The owner claims that the charger and the cable look to not be damaged. The most probably scenario is that this was a battery fault or one of protection circuits/sensors.
