Hi everyone! I wanted to ask if anyone experienced issues like this with theri New 2DS LL/XL.

So one day I noticed that my 2DS is going low on battery so I plugged it to charging though what was wierd was that console was looking like it’s not charging and was stuck at 1%. At first I though it was issue with charging cable so I replaced with new one and still not charging. Then I did like force hard reboot (long power push) and subenly battery is at 99%. Did anything like this happened to anyone?

    Yes it shouldn’t destroy them right away, especially if they’re new. But if you already have doubts about the battery’s life or monitoring, discharging it fully can make things worse, because that’s just how that chemical process works.

    Normally the monitoring gets reset fully by charging the battery and leaving it on the charger for a few hours. Which is why people don’t encounter errors too often, since most charge things overnight.

    It’s known that Ninty uses some damn good batteries in the DS-3DS so they tend to fine with discharging, but it’s not a good general advice.

      You’re right, it’s poor general advice; normally batteries function as they should with a few hours in a charger. In that case I would not recommend discharging a battery as it harms the overall lifespan of a battery.

      But when things aren’t normal, and it’s an issue with battery capacity not displaying properly, and charging to full didn’t fix it, discharging is a reasonable next step to be taken before getting a new battery or checking fuses. If a battery is already in poor health enough that one discharge-recharge cycle makes an appreciable dent in the remaining life of the battery, it has very little time left either way and needs to be replaced soon.

      Some more research seems to back this up; advice to discharge batteries when having issues is present in most battery troubleshooting/repair guides, on forums, and in various device manuals. I stand by my original advice to OP given their description of the issue; and I find “Charging to full is completely enough to recalibrate the monitoring circuit.” to be demonstrably untrue in many situations.

      Given all that, and multiple personal experiences with issues being fixed by discharging (and not by just charging), frankly I don’t see my thoughts on this changing much and I’ll continue to use the method as a troubleshooting step when restoring and fixing devices as long as it continues to work. You’re free to give whatever advice you wish, and I’ll do the same, but I don’t see much point in continuing this discussion.
