Hardware Battery charge indicator gone totally crazy

[stewacide]

The battery level indication on my Switch has gone totally crazy. It jump around between random levels every second: 100%, 5%, 37%.... This is definitely a hardware issue since it does the same in OFW as in Hekate. Also bears zero relation at all to actual state of charge.

The real capacity seems normal: I drained it down in OFW to attempt to recalibrate (without result) and it took +8 hours. But it’s really annoying since it’s constantly flashing low battery level warnings in Nintendo’s firmware (I use the system mostly for Android).

I assume a sensor has just randomly gone nuts, since I can’t find any report of a similar issue from anyone before. What I’m most curious about or whether replacing the battery will resolve the issue; is the battery capacity logic/sensor on the battery itself or on the main board?

Isn't there a fix for battery in Hekate and under tools?

I will look, but I doubt any software tweak will fix totally spastic battery reporting. Watching it charge up it’s bouncing between totally random numbers no relations at all to the battery’s actual charge.

Is this part of the battery or the soc?

IIRC the option was removed because Hekate now does it automatically on start. But I might be thinking of something else.
@stewacide See if the option is still there, if it is give it a try.

exactly right you are but that didnt helped (i had it aswell and it didnt helped). i got a modchip (rcmx86) and it had a battery gauge fix option in fusee suite..that helped (sorry without modchip i dont know other solution)

Damn, now I can’t get it to boot. Just gets stuck at the low power battery charging screen (black screen with battery at upper left, in this case flashing and indicating charging but seemingly not taking a real charge).

Seems letting it drain down was a really bad idea

Should have followed up sooner for those with the same issue. I packed the Switch away for a few months and after that it fixed itself. I probably could have done that right away by physically plugging in and unplugging the battery. Although now weirdly it reports as an over capacity battery (6001mah to be exact), but otherwise works.
