Re: That probably explains..
"If the battery degradation is so great as to warrant this, why not fit a bigger fecking battery to start with..."
Because that would only change the use case, not the outcome. With a bigger battery, users would likely do more - leaving it streaming music, not switching on low-power mode, keeping the brightness up high and so on. Wouldn't change the fact that the number of charge cycles is finite, and as battery performance decreases more and more technological patches are necessary to maintain usability.
