I posted about the Toshiba battery. 20 years ago cell phones resembled a
brick because of the battery size. Within a few years the battery was
minuscule. There was little advancement over the years in batteries as
the
"pressing" demand was not there. Arguably there was always a demand.
Amazing what they can do when they want to.
Yes battery tech to some extent, but a lot of cleaver tech in how they
use the battery nowadays to get long service times;!...
That applies to all batteries.
