That's a great TL:DW;

Now I want an iPhone that can charge in 20 minutes. :)

And with that, hopefully we can put this argument to rest.

wow... the idea that the anecdotal evidence of some youtuber should be the proof, not the engineering and chemistry knowledge of people who designed the battery and charging system and know how it works, is on par with the belief that global warming is caused by farts of the turtles carrying the earth. sad noises.

I always thought that charging beyond 85% or so is what degrades batteries. The LiPos of my quadcopter actually actively reduce their charge if left sitting somewhere for a longer period of time. To prevent them from going up in flames.

This is the type of scientific method that can put all this nonsense to rest. I really appreciate their work proving that the difference between fast/slow/30-80% is insignificant to the majority of people.

Thanks!

This isn't a fair like-to-like test though. They used iPhones, which use one battery and then for their 120W test they used iQOO 7, which has two batteries that charge in parallel. They aren't testing the charge rate effects on a single battery, but just how different phones behave.

While it's an okay test to see how certain models of phones hold up, it's not a test for longevity of a single battery using fast and and not-as-fast charging.

So the title, as it often is these days on YouTube, is misleading.
