I am playing Jurassic World Evolution 2, works great on Deck out of the box.
I also have Hades in queue.
They didn't check my laptop or mobile phone, however I didn't really hold any illegal materials.
Just don't bring any food, or any other prohibited things, they care more about real things than files you have in your laptop.
I had all my work related files uploaded to proton, just in case (I was going as tourist, planning on studying).
Good luck :)
You can try InnerTube of you care about music. It is like YouTube Music, but without ads, and can download the songs.
For videos, I am using ReVenced.
Non replaceable batteries are on iPhones, since they are paired with the motherboard, and if you replace it, iOS will keep warning you every day about a non genuine battery presents in your device.
