According to a report by the Chinese Website GizmoChina, there is an isolated event where the battery of a Xiaomi device exploded, while it was being charged. 

The most notable battery explosions can be accredited to the Galaxy Note 7 by Samsung, due to which Samsung had to withdraw the device from the market worldwide. 

There have been isolated cases of other smartphone companies meeting the safe fate due to faulty batteries.

According to a Weibo post, the incident occurred when the phone was plugged in to charge near the owner while he slept. The smartphone reportedly went up in flames but did not cause any harm to the owner, as it was in a protective case. The case was able to subdue the effect of the explosion which prevented damage. 

Since it's Xiaomi's Mi A1, we aren't entirely sure where the incident took place, as it was launched globally by the Chinese company. The Mi A1 was a huge success in India and prompted the eventual launch of the Mi A2. 

Since this is an isolated event and a first for the model, it's fair to say that this is a one-off case and is not prominent for every Mi A1 device.

The explosion of a battery can be attributed to various factors such as a defective battery, defective charging cable or adapter, third-party cables, and others. 

As of now, it is not known whether the user was using a third party cable or had erratic charging patterns that may have caused it to explode. The affected user reportedly said, that the phone has been in use for 8 months and has reported the issue with Xiaomi's customer care. 

The Mi A1 launched a while ago and sports a 5.5-inch LCD display. It comes with Android One out of the box and is powered by Qualcomm's Snapdragon 625 chipset. The Mi A1 comes in two configurations i.e. with 4GB and 6GB of RAM.
