Hi, I hope someone can help me with this problem which is driving me crazy.
I bought a broken Switch Oled, after replacing the M92 and BQ and fixing the display connector it started charging and correctly booting. I fully charged the switch, I tested it with some games and everything was working fine. I discharged the battery by playing and i recharged it with a unofficial charger and everything was fine. I modded it with a picofly, I installed hats pack and everything was working fine. I started playing and everything was fine. After one months I gifted the switch to my gf, she played it some days, than one day she tried to charge it with my charger and the charge light was flickering on the cable. The switch was only slow charging while connected to a PC, the wall charger wasn't turning on. After a full charge with a computer she played a bit and than the switch was not even charging with the computer. So I replaced again the M92 and BQ, and now the light and corrent meter is turning on, but it is displaying 15V 0.01A on both side. The switch display the charging icon on the top right but the battery is actually going down, but it does boot fine and games run fine. I literally don't know how to proceed with the troubleshoot, I checked voltage on the BQ chip and found out that VBAT and VSYS are both 3.87V (same value of the battery voltage registered at the two golden battery motherboard connector), but also the VBUS pin display 3.87V. I tried to look for hetake battery info and it is showing a strange reading on the Fuel Gauge IC. I've read on other forums that it may not be a problem. If you have some suggestion let me know, this switch is driving me crazy.
