Xiaomi issues clarification on 'fake' Note 4 explosion video
According to Xiaomi, they replaced the customer's damaged phone; the old one didn't explode.
The video in circulation was recorded at a Kerala store and didn't feature Arjun, the alleged customer in the incident, at all.
Meanwhile, here's how you can ensure a safe environment
Keep an eye out for danger signals. Stop charging if the phone becomes too hot. Let it cool before re-charging.
Use branded first-party chargers. If you are charging via USB, it is better to use the one provided with the phone.
If you notice the battery swelling, remove it and dispose it off at authorized facilities. Do not discard it in the trash.
