One extra perk of buying a gaming phone is that they usually offer a range of accessories to go with them. These vary by manufacturer, so there's no hard-and-fast rule on what to pick up. Strap-on coolers and fans are a good way to maintain performance and reduce long-term damage to the phone's chip from overheating. If you find it fiddly to play on the touchscreen, you might also want to grab a Bluetooth controller. As with any phone, a protective case and screen protector are always a good bet too.
