Unlike conventional batteries, supercapacitors have an exceptionally long lifespan, lasting hundreds of thousands of charge-discharge cycles, whereas lithium batteries typically last only five years or less.
So, what’s the conversation rate between charge-discharge cycles and years?
I don’t know if it’s the same in Europe, but here in Canada, I’ve only seen the option to trade in old phones when you’re buying one of the fancier phones with a bunch of bells and whistles I don’t need. There no way they would give me enough for this phone to make up for the price difference.
Also, 40 months is an unusually long time to be holding on to the same phone? What?
