joy-con glitches when used wirelessly for around 45 mins

so i replaced the casing on two joy-cons about a month ago and a week ago I noticed that the right one would glitch when it was in TV mode for around 45 mins and would completely die for 5 mins before reconnecting to the switch, it works fine in handheld mode, but glitches in TV mode and handheld mode.

so uh edit-

it kinda dies for 5 mins still but now you have put the switch in handheld mode and then take the joycon back off for it to be able to be used wirelessly again.
