There is no charging in RCM so yes...Can we not resync battery by charging it to 100% in Horizon then going to RCM and charging it there to 100% as well.?

Nope. Let me reach home and my pc i will qote u sth - hard to search on cell while driving even in traffic.RCM charges battery just fine. Tested by me and many others.
being in RCM drains battery but doesnt charge when connected
There is no charging in RCM so yes...
This is incorrect, it charges fine.Nope.
My battery just got desynced and switch shuts down at 49%. I will charge it to 100% in horizon then will leave it charging in RCM and report back if it fixes it.
Ok. I was wrong sorry.This is incorrect, it charges fine.
I tested this with an USB power meter, see images below:
Console turned on:
Console booted payload:
Console in RCM mode:

As the title says I was wondering if we have any knowledge if it’s something that can be fixed. Mainly because I’m curious if it’s worth taking my switch apart repeatedly to fix the issue. Also I haven’t seen this anywhere so sorry if it’s been asked
No it wont fix it
Ok. I was wrong sorry.
So, Switch charges and does not charges in RCM. xD
The results (battery was 89%):
The switch can charge normally the battery, if the BCT is intact!
In RCM AND in hekate menu.
*BCT is the boot configuration table that autoRCM corrupts.
Tests showed that it was charging with the same current, as in Horison OS.
The current it was drawing with 89% battery, was 800mA - 1000mA, using Switch wall adapter. On PC, it was the max the hub could give.
------------------------------------
The switch cannot charge normally with a corrupt BCT (AutoRCM).
In hekate, it shows similar behavior (read below).
Extra emphasis on the "normally".
With autoRCM, basically a corrupt BCT, the switch behaves differently.
There are 2 behaviors that I saw when connecting to the switch wall charger:
- Common - It was draining 140-250mA.
- Common (in hekate) - 200mA - 400mA
- Rare (normally if you connect charger after powering off from HOS) - Drain of alternating 250mA and 1000mA, with surges of 2.5A.
------------------------------------
Summary - facts:
I don't know for behavior .3 what really happens and what Switch does. This can be easily examined, by connecting a current multimeter between battery and switch and check the readings.
- Switch can charge completely normally in RCM or Hekate with a BCT intact
- The percent % in Horizon OS, after a RCM charge, is not fake.
- Switch does not charge normally with AutoRCM, a.k.a corrupt BCT.
- Either it charges very slowly or sometimes with a broken slow/fast/slow/fast charge pattern:
- Or this behavior is current taken from the USB controller or the BPMP (Nvidia's Boot and Power management processor)
- In AutoRCM, the Charge IC probably can't update the battery calibration file and could make the percent fake.
