Having recently read this question with its answers it seems like I should never ever charge my phone/laptop/tablet unattended. It also seems like I should always be worried about my devices exploding without any reason, and keep them locked in some super-secure bag or safe or something at all times, but that's not how we use our devices.
I have my phone in my pocket, in my hand or against my head all day, and at night, it's charging beside my bed. I'm assuming there's about a billion people doing roughly the same. I also usually have my laptop on the top of my lap, with its battery less than a centimeter from my legs, and I can't be alone there either.
I'd like to quantify this risk with some statistics, to compare it to, say, the risk of dying by falling from a chair (8 people in Sweden in 2014, 8e-7 of population per year) or by bicycle accidents (roughly 25 people per year in Sweden, 2.5e-6 of population per year).
How many people die or get injured by LiPo batteries in phones/laptops/tablets (with the casing on)? How worried should I be?
