Nintendo Switch battery drained when docked and playing
Hello, I recently picked up a used Switch. This happened when I was playing in docked mode with the original dock and cable.
Things seemed good, but the other day, when marathoning a game, I noticed the screen kinda flicker between pixelated and regular resolution. I realized that despite being in the dock, my switch said it was at 1% battery. I stopped playing and left the console for a bit and now it’s fully charged.
The battery seems to have drained while I was playing pretty intensively for a fair amount of time. I’m wondering if this is a sign of some sort of issue that might be worth fixing.
I haven’t opened up the switch to check if the fans need cleaning, although I wonder if that’s advisable. Not sure if this is a sign that some part needs replacing.
For reference, I’m also using one of those USB adapters to use a PS4 controller with my switch. I don’t know if that also significantly increases power consumption. Also, my room is air conditioned.
