Yeah but what I meant is after the TX device sends the payload, if you let the device connected for a bit it will most likely be charging, but if you remove it from the switch instantly after the payload is sent, it will probably never charge it and after some times it gets fully discharged...Not that he removed it too fast, maybe that he's used his Switch for days and the capacitors discharged. Remember, we have the sleep bug fix. No reason to interact with the dongle unless you're making changes (adding games, etc.). What TX has never told us is how long the capacitors hold power.
So probably if you always send the payload and keep the device after booting the OS for a few time every time it won't probably get this problem and be always fully charged.
