I remember reading that using either Lakka Ubuntu or android will wear the hardware faster than using HOS to play either emulated games or downloaded games
can anyone tell me which part will wear down if i kept using Lakka Ubuntu or Android
If you use anything at all it will wear down eventually

. The switch is a tablet, your going to get less battery lifetime if you use higher clock speeds or some programs/games as opposed to others. It doesnt matter what OS you use including horizon.
If your super paranoid you can always leave it behind a glass case though

.
Your odds are much higher you will brick your switch within the next 5 years from incorrectly updating Hos, than your switch’s battery being completely consumed.
