I got a new iPhone 13 Pro Max, and ordered ahead of time a Belkin Magnetic Wireless Charger (Single device). My phone mostly stays on it OK with no case. With my standard case it wouldn't stick to it at all. When I stay standard case that is a TPU case for it off Amazon that is not specifically Magsafe. I will say that my phone has no real issues staying on the official Apple Magsafe puck. Even with the puck in a portable stand. Thankfully I ordered the Belin through Amazon and returns are painless.
