TL;DW: Fast charging over 2 years only degraded the battery an extra 0.5%, even on extremely fast charging Android phones using 120W.
And with that, hopefully we can put this argument to rest.

It’s as if engineers knew what they’re doing.
If engineers were the ones in control that would mean something.
As I see it, phone manufacturers have zero reasons to keep the battery degradation low, but many reasons to push advertised capacity and charging speed. If you were cynical, you could also assume that they’re trying to make sure the battery doesn’t last too long because they want to keep selling new phones.
I think we all know that if an engineer went to upper management and said “I can charge these batteries faster, but it degrades the battery life by 20% over a year.” they would have said “Do it! We won’t mention that last part.”
Engineers have the best of intentions. The Bean counters have very different intentions and they’re the ones that corporate listens to.
You say that like batteries don’t need replaced every few years or that they didn’t design the Samsung Note 8 phone that kept catching on fire.
Engineers get told to make the phone charge as quickly as possible, while still lasting 2 years. After that, the company with those engineers pretty much wants the battery to fail, so they can sell a new device.
The one thing I wanted to see from that video, was also just testing the batteries until they went below like 75% capacity. The initial degradation may start off similar for capacity, but that doesn’t mean it will stay that way.
Yep. I’m gonna miss real engineering with the coming Ai-driven Idiocracy.
