> Interesting that this effect may be a byproduct of automatic scaling the CPU frequency based on remaining battery capacity, rather than the newer OS versions being purposefully poorly optimized (like most people assume) 1. If such a common complaint has such a simple fix, why isn't Apple shouting this information from the rooftops? Why do we need anecdotal information posted on Reddit to figure this one out ten years after the launch of the first iPhone? 2. Being a byproduct of automatic scaling or the commonly cited flash degradation doesn't explain the abrupt spikes in the search for "iPhone slow" around the release of a new iPhone (Google Trends: https://trends.google.com/trends/explore?date=all&q=iphone%20slow https://trends.google.com/trends/explore?date=all&q=iphone%2...). Could it be a purely subjective, psychological effect? Does anyone have actual benchmark data on this?
