    It had nothing to do with the capacity of the battery. It had to do with providing instantaneous high current when doing something demanding. Old batteries couldn’t do this and voltage would drop to unsustainable levels causing a brown out/black out.

      Because the capacity was diminished…. New batteries didn’t have this issues since they were… well new…and had the capacity.

      In a fully charged battery you could run demanding stuff, it’s only when the charge depleted that it became an issue, which is it couldn’t acces the capacity for the extra voltage anymore.

      Without capacity, you can’t provide the high current… they’re literally related and go hand in hand………

      Again, you’re literally explaining more or less the same thing, in a far less technical way… so sure to a laymen you’re “correct”, but that’s where it ends.

        But it’s NOT a capacity problem. The phone would turn off and then turn back on. The batteries still had power.

        It’s funny you say I am less technical when I describe the exact technical reason for a shutdown. You just keep saying the same thing.

        It’s a chemical aging issue with batteries. As they age they cannot provide the same amount of current at the same charge level.

        Current draw is not even close to steady, there are lots of spikes. It’s the spike that is a problem.

        If you had a new battery that had say 500mAh of charge remaining the issue wouldn’t happen. If you had an old battery with 2000mAh of charge remaining it’s very possible the issue happens.

        Hopefully this is a simple way to describe to you that capacity does not matter. It’s all about current.

          Yeah… no… that’s not the case at all. A larger battery with more capacity that is aged would do the same thing as a brand new battery with the same capacity.

          They’re a function of each other and your description is now contradicting itself. Capacity is the end function, without voltage can’t have capacity… you’re claiming otherwise.

          A 500mah battery can’t provide the same over voltage as a 2,000, you’re claiming it can, come on dude lmfao. Without capacity, it can’t tap the over voltage needed, so the phone crashes and reboots, until you try the same thing. The phone effectively becomes useless after an hour since it can’t do anything demanding anymore, I never said it was dead….

          Current is a part of the calculation to get capacity…. You can’t have capacity without current (A)…… you can have current (A), but it’s useless without voltage, and voltage and current gives us… capacity!!

            I’m done explaining. You’re still wrong. I understand max capacity is voltage*current but that literally does not matter. Study some electrical engineering and then get back to me.
