How to check wearing level / battery life of a Joy-Con?

Ch3ck3rM0n · Feb 7, 2024

Hi all,

does someone know how to read out capacity / wearing level of a JoyCon?

I want to find out, which of my second hand controller needs a battery replacement.

My OLED is also modchip, if there is a Hekate extension or for Armosphere to read out.

Please let me know.

Thanks

I've never seen it.
For the main battery it is shown in Hekate but for the controllers such information doesn't seem to be available.

So u think the only way is measure the voltage fully charged via tool (multimeter) after disampling?

On DBI, tool settings > system info.

Thanks, how good or bad a battery is my interest, thanks for the info. I'll see if DBI has enough because thats a lot easier then connecting them to a PC.
