Hacking Battery Problem After

[EpicLPer]

I think switch can recalibrate itself. There is a guide by Nintendo for People who are on 3.0 I charged mine to 100% (It stucked on 95%) now it is down to 75% instantly, so I asume it recalibrated himself.

If you do so I suspect you'll calibrate it to a lower mA tho as it really is since the calibration value in the Switch OS itself is completely off to begin with.

Funnily enough, I thought for a second that I damaged the right Joy-Con rail pins or the USB-C port, or that I shorted some pins I shouldn't have, because I wasn't being able to enter RCM, and my laptop was instead making the Horizon OS boot. I was beginning to worry when I noticed the battery problem yet again.

I can confirm that during the battery issue there is a strange effect on the ability to enter RCM that can make you think you've damaged the USB C port. But it vanishes as soon as you do the battery connector fix.

Maybe, but it fixed it at least, I get low Energy now and I am at 7% atm. so it seems to work agian.

You obviously have a different problem than ours because we can't do the nintendo method : again the switch turns off every minute or so when it reaches 30%, it's quite impossible or really tedious to then drain it to 0% (and most likely not good for the battery to charge it 1000000 times just to turn it on every minute).

Also I tried to discharge it completely in RCM and charge it fully on Horizon and it didn't fix it. So again, it's a different problem.

Maybe, through I had the same, I Spent tons of hours in Linux and now my Switch shutdown on 30% died. So yeah, I through I am on same boat.

Not impossible or tedious. Just consumes time. Do what I said a page back and youll get it to die at 1% and it will charge the whole way.

But it's still a stupid idea to charge your Switch ~100 times just for this when opening it isn't super hard. I know some don't know how to but then again if you're not willing to risk your console you should never hack it or run stuff that's not designed for it on it.

It doesnt take 100 times. If you step down power consumption, you may have to charge it all of two times.

I tried that method at least 5x. There was a marginal improvement, but still was shutting down without warning at a higher percentage than it should. Disconnecting / reconnecting the battery fixed it completely.

It works 100% of the time for me regardless of desynced percentage, so dont know what to tell you there. Removing the battery fixes it because it probably clears nvram or something. Unfortunately, I'm not opening my Switch every single time I want to do something in linux on it.

 

[Shadow LAG]

Using my own compiled coreboot + kernel + rootfs didn't yield positive results. My Switch is yet again displaying the battery discharge issue. Funnily enough, I thought for a second that I damaged the right Joy-Con rail pins or the USB-C port, or that I shorted some pins I shouldn't have, because I wasn't being able to enter RCM, and my laptop was instead making the Horizon OS boot. I was beginning to worry when I noticed the battery problem yet again.

@Shadow LAG Since I've been able to replicate the issue not once, but twice, using different rootfs, are there any kind of tests you may to perform? Just let me know.

I'm going to do exactly what you did this weekend and see if I can get my switch to be effected. For now, please list your firmware on switch and joycon, pin method, and purchase date. Also we're you effected before, did the battery trick, and then re-effected?

I mean Linux is still pretty shitty on the Switch, I don't see the need to boot into it all the time. I just wanted to grab a nand dump, and now you don't even need linux for that.

And it takes all of 5 minutes to open the Switch - much easier and quicker than draining and recharging multiple times.

 

[guily6669]

And what about anyone who just put all random stuff in the rails or joy-cons, entered RCM and sent payloads...

Did anyone who not boot Linux ever had it?????????

You're entitled to your opinion. I can let it sit there while I do other things, I'm not that obsessed with it. And yea, I guess you wouldn't need to boot into Linux often if you aren't doing anything that requires it. Imagine that.

So what work are you doing that requires a buggy implementation of Linux running on a Switch specifically? It's a novelty.

Who said anything about being obsessed? I'd rather just spend 5 minutes doing a definitive fix then dick around for days with discharging and recharging.

I can confirm this as well.

Switch version: 5.0.2.
Pin method: shorting pins 1 & 10.
Purchase date: that's a big blank for me. I bought it through a reseller almost a month a half ago, but I don't know when they bought it. It's clearly an US console, that much I can tell. If it helps, its serial number is XAW40008842196.

And yes, I fixed the issue the first time with the battery trick, then got the problem a second time. I don't know how to check the Joy-Con version, btw.

 

[naddel81]

so this only occurs when/after using linux?

Yes if you are ready to disconnect your sw battery(or stick to 30% battery bug off) then you can try the above payloads

 

[re.lax]

Really wanted to play around with Linux this weekend but might wait a bit to fix out this kink or too. Ooooor I’ll probably still do it anyways lol.

 

[subcon959]

If only proper hardware power switches were still a thing.
