I have 0 expertise in phone battery replacements, but I have one recent experience of a neighbour in my apartment building recharging his electric scooter, and a dodgy (or cheap or both) battery in the said scooter blowing up at 3am in the morning on a cold winter night decimating the neighbour's apartment and with sprinklers flooding two stories with water. Residents from both floors could not return to their apartments for a day (the floor above) and two (on the floor where the explosion happened). The fire brigade attending the scene told me that the only reason the neighbour survived the blast was due to him recharing the battery in a spare bedroom. The explosion nearly vapourised the bedroom door, threw what remained of it out, and it blew the window frame out as well. There was a gaping hole on that side of the building. Luckily, the ordeal took place seven stories below me, but, no, I do not want the same thing to happen anywhere in the nearest vicinity ever again. No, it doesn't console me that phone batteries are smaller, and the physical damage would be less. If a dodgy battery in someone's phone explodes whilst their are handling the phone in their hands, I do not want to wish anyone to be that person who could lose a limb, an eyesight, an eye (or both), or a permutation thereof. People do stupid things, and some will do absolutely them one day (i.e. manually installing a dodgy knock-off battery into their phone and accidentally shortening the contacts).
