> Realistically batteries currently made reach end of service life around 3 years, previously it was around 2. People using devices heavily (gaming/videoconferencing) or living in hot climates will have shorter service life.

I was perfectly happy with the battery life of my iPhone SE and my iPad Mini 4 far longer than just three years. Those batteries were not "currently made", were they? And it was not like I was a light user of those two devices...
