You clearly didn’t grow up before lithium batteries. Before lithium, batteries sucked and they sucked hard. You would spend a small fortune to buy 5 lb of batteries to put in your tape player, CD player, remote control toy, anything portable and then you would get between 5 minutes to an hour of total use time. Or, if it was you rarely used the gadget, or it was something like a remote control that were only on for incredibly short bursts as you push the button, you would leave the batteries in it until they went dead. But then you got the treat of opening it up to replace the batteries and finding that they leaked all over the inside and destroyed the device.
I have lost so many portable devices to leaking batteries that I can’t even begin calculate how much it’s cost me. Before smartphones, I had probably spent upwards of $1,000 ( in today’s money) in calculators alone. I don’t even work in some kind of math-type job or have a mathematics type degree.
