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.

    The OP said “all phone ma manufacturers stop charging at 80%.” That means phone manufacturers have a definition for 80% and 100%, and they use 80% universally while showing 100%. The first part is true, the second part isn’t. Some manufacturers show 100% when it’s actually their definition of 100%, meaning charging to 80% manually on those phones has value in prolonging your battery, whereas charging to 80% manually on the phones that cap at 80% doesn’t have value.

      Lol um no they didn’t.

      So what they call “100%” is not actually 100%. Your phone will not charge your battery to full.

      Someone else mentioned “80%” when you didnt understand the first comment, but they didn’t say “all manufacturers stop at 80%” either.

      You have got to be trolling at this point to be this obtuse

        Original comment:

        Here’s a fun fact: phone manufacturers know this. So what they call “100%” is not actually 100%.

        My response, which was a small clarification:

        That depends on the manufacturer, some do, some don’t. My phone has a setting to control the max charge, so I set it to 80% when I got it.

        And the follow up from a different user:

        Yes, but that 100% is not really that. It has been programmed to display that percentage, when i reality its 80%.

        And my response:

        No, I’m saying that not all manufacturers have that limit, and it’s a relatively new setting (last few years). If you have an older phone or something not from the top few manufacturers, it might not have that feature.

        Then our conversation started. That’s the context. Here’s your first comment:

        Exactly, which is neither a user setting or relatively new. Battery manufacturers have always had to decide what voltage is what state of charge (percent).

        The user setting where you limit it to 80% is on top of what the previous commenter was describing

        And then my response:

        Sure, if the manufacturer sets it to not charge to the max. I’m saying some manufactured charge to the max by default, hence why that setting is useful.

        My point is and has always been that this isn’t universal, so don’t just assume that your phone stops charging at 80% if battery longevity is important to you. Check if your phone does it so you can know.

        If anyone is trolling here, it’s you.
