Most High end devices have 7 years of update now (Samsung, Google pixels). No current Gen battery can last that long.
because the manufacturers are not required to make them last that long. if they were required to, they would alter the chemistry / capacity of the battery instantly and this would be solved.
Is there a lithium ion battery chemistry that lasts 8 years after being manufactured and ~3,000 discharge cycles without significant (10+%) degradation?
LiFePO4 can (https://iopscience.iop.org/article/10.1149/1945-7111/abae37/... Figure 1), although I would still like to be able to change my battery.
