How to handle getting yelled at by MIL?

So we went to visit my MIL and my son fell asleep watching a video on my phone and the screen didn’t turn off automatically causing the phone to overheat it was in hands/lap it was with him for 3 hrs. My MIL got angry and raised her voice saying it would explode all over him and disfigure him and that i would regret it and she also said he’ll suffocate and die. She also sent me a video of a person with their face burned from their charging phone apparently. My phone is an iPhone 12, he always takes my phone and fall asleep with it and it would get hot every time but I didn’t know it could explode or cause suffocation, and I feel like a bad mom. She always makes me feel this way I hate that I can’t stand up for myself and get chocked up every time. Am I a bad mom? I didn’t know it was dangerous.
