    Is there any evidence that this really matters on top of the protections and limits that are already built in and obscured from the user? There’s such a cult around this feature, but I’m not convinced.

      What I don’t understand is do any of the OEMs giving this feature also combine it with passthrough power? So besides not charging the phone at 80%, it would keep it working using the wire instead of the battery.

      Fair question. I’d assume that the buffer which the BMS/low level firmware reserves is relatively marginal. Having too high a margin at that (low) level would take away a lot of capacity and might make people mad

      Honestly I thought it was standard for modern electronics, or cells themselves, to internally consider 80% as full

        This is untrue. Overcharge protection is for preventing catastrophic events like the cell catching fire. You can easily verify this by measuring the voltage at full charge.

    I thought they had it, like a lot of phones, Samsung has a limiting to 80% or even disabling fast charging

      This is only the ability to turn it on manually. My old Pixel 4 lives on a charger and does it automatically.

        Is this the Adaptive Charging feature? That’s the only thing I see in my Pixel 5a.

          If you keep your Pixel plugged in for a few days, it will give you an option to limit charging to 80% (or maybe just turns it on on its own, not sure about that). There’s no other way to activate it currently, but that should change soon (the Adaptive Charging option will have three options instead of just on/off).

      Honestly, if I have the option to keep it toggled on/off I’m fine with it, but I also don’t see it in my latest update which came in last night. But not too concerned yet (Pixel 8a) so it’s still pretty new I guess. :)

    Is this different than Charging Control? I’m on 7 Pro CalyxOS and have been using that since I was on 4 XL [a couple years ago]. I figured it was AOSP…

    Edit: added a cleared timeline.
