I think probably a much bigger problem is app bloat. Devs are usually using very recent if not brand new top end devices to test and develop against which naturally makes several types of performance degradation invisible to them (“works on my machine”). Users on old and/or low end devices on the other hand feel all of those degradations.

If we want to take increasing device lifetimes seriously we need to normalize testing and development against slow/old models. Even if such testing is automated, it’d do wonders for keeping bloat at bay.
