I was just doing random stuff on my phone and went to click a button near the top right of the screen, and was mildly horrified to see “1%”, so I immediately put it into the charger, where the phone promptly started showing “0%” for the next ~30 seconds. The phone never died.

Has this happened to any of you?

    Not entirely sure if this would apply in your case, but for future reference you can sort of “recalibrate” the battery percentage by:

    1. charging the device to 100% and keeping the charger on for a while (normally a few hours)
    2. drain the battery until the device shuts off
    3. charge the device back to 100% without unplugging it (keep it connected for a few hours again just to be sure)

      That generally works when replacing OEM with OEM. But when you replace a 3000 milliamp hour battery with a zero lemon 10,000 milliamp hour pack, Samsung’s algorithm just couldn’t sort that out.

      My old Note 4 ran for years with a giant zero lemon pack It always thought it had about 27 hours worth of life at full charge, but I would constantly get 40 hours plus.

      It didn’t help that old phone, there seem to be limits to just how much adjustment it can make (including to dying batteries with less capacity also)

      I don’t like doing that because it wears the battery. Better to have slightly inaccurate percentages than to actively make the long term situation worse

        1 up-down cycle doesn’t wear the battery, negligible. It would only count if you would do this every day. It’s recommended to calibrate a new battery

        I was under the impression that’s not how LiIon batteries work. Was it a NiCad or some older type?

          I think they are referencing how Li-ion batteries just generally have a limited number of charge cycles, so they don’t want to waste a whole one.

            That’s why I asked. I knew about the cycles but I’m not aware of it causing any additional wear. I thought maybe there were new findings recently. I’ll have to go look myself, just to satisfy my curiosity.
