The problem isn't very prevalent in Android devices, because they have more "voltage headroom". The chipsets are not pushed to the limits / the red line, so battery degradation won't result in performance drops or sudden shutdowns.

Sudden shutdowns do still occur for some devices, but it is nowhere as iPhone devices pre-throttling. It's also something that didn't affect previous iPhones before the 6, because those devices did not have a very thin redline.
