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.”

Granted, with all the planned obsolescence happening, you could also argue that engineers "knew" what they were doing.

Planned obsolescence happens but it's not as common as most people think it is.

[-] umbrella@lemmy.ml 1 points 3 weeks ago

its exactly as common as people think, when most people's phones are lasting 3 years tops.

And probably not as intentional as most people think it is vs just laziness and maybe a lack of planning.
