That’s true for kinda sorta everything? Battery manufacturers don’t want to have to deal with creating a bunch of custom battery runs, so they end up standardizing and higher level manufacturers buy from there. This is especially true in situations where space isn’t at an absolute premium (like it is in a phone). Open up the battery pack for your cordless drill and you’ll find very standard batteries inside there, probably hooked up in series to get to the desired voltage.
I use a Logitech Marathon M705 mouse that lasts 3 years on two AA batteries, according to Logitech. I’ve got Eneloops in it that I’ve been using for around 10 years now, and I’ve had to charge them maybe 4 times in total?
