If a game runs smoothly for twenty minutes and then starts to stutter, the phone has probably got hot. This is the phone protecting itself, not a fault.
The chip that runs a game turns electricity into heat, and a demanding game keeps it working hard for a long time. A phone has no fan, so when it gets too warm it turns itself down. Apple's help page on hot iPhones says that performance is then reduced, with lower frame rates in some apps, that charging slows or stops, wireless charging too, and that the screen may dim. Apple gives 0 to 35°C as the comfortable range around an iPhone. Charging while you play, a thick case and a warm room or direct sun all make it worse.
The coolers in this range are semiconductor coolers, often called Peltier coolers after the effect they use. Each has a metal plate that gets cold when powered, with a small fan behind it to carry the heat away, so they cool much harder than a fan alone. They click onto the back of the phone with a magnet and come off in a second. Several have more than one fan speed, and one has a charging port that passes power through to the phone, so you can charge and cool at once. They need power while they run, so check how each is powered before you choose: a cooler on a cable adds another lead to manage while you play.
A magnetic cooler needs magnets to hold on to. MagSafe-compatible iPhones have them built in; Apple says iPhone 12 and later are designed for MagSafe, except iPhone 16e. Other phones need a magnetic phone case or a magnetic ring stuck to the back. For a phone with neither, clip-on phone coolers grip with a clamp instead.
Put the cooler over the hottest part of the phone, which on most phones is near the top of the back, close to the cameras. A thin case lets most of the heat through. A thick or rugged case holds it in, so take that kind off for long sessions.
Anyone with a pacemaker or another implanted medical device should ask their doctor about magnets near it. Apple's own figure for its MagSafe accessories is to keep them more than 15cm from the device.
A plate colder than the air can gather tiny drops in a damp room, as a cold drink does in summer. Wipe the cooler and the phone dry and use a milder setting. Do not cool a phone that is not warm, and never put a phone in a fridge or freezer.
Yes, through a cooler with a pass-through port or on a separate cable, but charging adds heat. Where you can, charge before a long session, and keep a power bank or a right-angle cable for the times you cannot.
