@duc Most people will have some sort of a phone, so that's one, and then people are gonna have various other electronics on them, with varied probabilities, and then some people are not going to have a phone... but I imagine it comes out to >1 in the balance.
@Dee smart watches have become somewhat common, laptops are a thing, and mobile phones are pretty common even in developing countries i believe? which is why it probably is more than 1
@duc@Dee folding phones are starting to come with two batteries to fit into the gimmicky shape. Plus I imagine many diabetics have at least an extra battery for a blood sugar monitor or insulin pump, though they might not be lithium.
Does every set of wireless ear buds count as 3 batteries?
@samueldr@rune@duc I'm gonna go with yes, If you can take it out and power something with it independently... which means that packs assembled from individual batteries also count as separate batteries.
@duc@Dee@samueldr this might be getting out of hand. Even if you only count physical packs Macbooks have a ridiculous amount of individual batteries.. Some with 4-6 discrete packs
