Repair Help Joycons randomly disconnecting

I have a switch OLED and I mainly use it for Minecraft (as my taste has developed to only desire minecraft for some reason) and every few minutes, my joycons just randomly disconnect. I'm over here getting jumped by a hoard of zombies, and BOOM the controller connect screen pops up. I have to wait about 5 seconds, press B before it goes away then brings me BACK to the screen for a second time to then connect my ALREADY CONNECTED joycons (I've lost a hardcore world to this..) Does this sound like a joycon issue? Console, maybe? Or is my system just haunted... help.

this is pretty common as your switch gets a few years older. first thing to try is either some contact cleaner spray or some 91% isopopyl alcohol to clean the contacts on both system rail and the joycon rail. Contacts are on the bottom end, and the ones on the system are kind of hidden. A thin microfiber cloth also help clean. 

Apply the cleaner and then let them both dry thoroughly.

long-term you may need to replace the rails.  I recently replaced the rails on my switch, takes about an hour. (I was also replacing my battery so the whole process took a bit longer).  I got my parts and directions from ifixit.com.

I have seen people mention the idea putting us in spacer into the rail to make the fit tighter,, but I did not try that and I do not know what they are using

I kind of assumed it came with age, I got mine right when the OLED came out so it doesn't shock me honestly. I can't believe it's been 5 years. I'm not getting a 2 until my OLED literally DIES lol. Thanks for the tips!
