I am charging my laptop with one of the “quick charging” phone chargers right now, currently it says 5 hours until full charge. Does this wear out the battery faster or something? Or does it make no difference apart from taking a little bit longer?

    This. I still keep my old 500mA phone chargers and use them on my phones to be gentle on the battery for slow, overnight charges. I am also a battery expert in my day job…

      😁nice!

      😄did you have the joy of working USB-C PD charging and dead battery with self protection and USB OTG support? (On embedded Linux 4.15)

      (Plug in -> 5vSAVE due to CC pull down on default -> power negotiation -> agreement on 20v -> death of Linux due to short interupt of supply on Vbus and no power from battery because of self protection -> back to step plug in -> 5vSAVE)🤪

      See I worried about this with my phones for a while, but then I realized I’m literally just doing the job of a charge controller for the phone which only cost about $300, and by the time any wear might show up from enjoying the fast charge capabilities I’ll have already have switched to a newer phone since I tend to upgrade every 2-3 years

        Batteries have a logarithmic degradation of capacity, meaning using the quick charge function will cause the capacity to drop about 10-15% really quickly, likely within the first year. So dumping the phone in 3 years is likely right when you hit the shallow part of the curve and the battery stops degrading much.
