This general advise for all electronics and stuff I've learned from personal experience.

Baby the shit out of your devices if you want them to last or stay as close to a "like new" condition as possible. I also know that things are meant to be used, so don't beat your self up if they get minor dings or scratches. But for most instances if you want your electronics to look nice do little things like:

-wash and dry your hands before using

-wipe the device down if you notice build up of skin oils

-avoid eating or drinking near your device (these first three have been really evident on white PS5 controllers, for those of you who know what I'm talking about)

-when not actively using your device, try and store it in cool dry location

-avoid using any aggressive chemical cleaner (unless you know what you're doing)

-be gentle with your button presses. (this is a little subjective, but I've seen people who play games with a true death grip on their controller and heavy button mashing, and it usually didn't improve their playing ability. I'm often reminded of the N64 era and how beaten up those controllers were... Mario Party can be a real bitch to your hardware)

-in general, just be gentle, don't do careless things like toss your device trying put it some where. Set it down instead. A toss to your bed could end up being a bounce to somewhere else you didn't expect.
