What would make you leap to that conclusion? That doesn’t follow at all, especially for the average non-technical user.
The shutdowns weren’t situations where the battery was draining to zero faster than it should have. They appeared to the user as random occurrences even with battery left in the tank. This was due to the battery no longer being capable of providing the right power when SoC power draw would peak. That’s why throttling the chip to run slower mitigates the issue.
The former. The random shutdowns would make you think the battery needs replacing, meaning you wouldn't need to replace the whole phone.
The latter would make you think that modern apps aren't able to run on it anymore, or you are suffering from windows-style software bloat.
