Apple - Does the iPhone 6 "CPU-throttling" feature stop after the battery is replaced?

It seems that the CPU throttling will stop once device's battery is replaced. In a statment to TechCrunch, Apple says they will throttle devices "only when needed."

Last year we released a feature for iPhone 6, iPhone 6s and iPhone SE to smooth out the instantaneous peaks only when needed to prevent the device from unexpectedly shutting down during these conditions.

As this happens "only when needed," replacing the battery should stop CPU throttling from happening. Explaining his experience with the same issue, Forbes contributor Antony Leather says that performance did increase on his iPhone 6 after replacing the battery.

My iPhone 6 was a prime candidate - I had actually replaced the battery myself a couple of years ago, but I'm a heavy user and already noticed its longevity had started to decrease again...

Finally, I replaced the battery with a new one from Amazon, charged it to be well away from the low power mode level and re-ran the test. The difference was incredible. The single core score rose from 1038 to 1562 - an increase of precisely 50%.
