I have some seriously bad luck with spicy pillows. I had a nexus 4 and 5 that had their battery swollen. Also an iPhone 6 and a Poco X3 pro. Also, a ZTE z959 and moto E4. I don't want a spicy pillow. I'd rather the phone turn itself off before the battery swells up but ideally it should automatically disconnect the battery and keep running off of the wall unless it is too hot, in which case, it should shut itself off.
