What’s the Best Mobile Phone for Gaming in 2021?

Do you like to play online casino games such as online blackjack, or online mobile games like PUBG? If you do, you might be wondering: “What is the best mobile phone for gaming in 2021?” Check out our pick of the top 5 gaming phones (listed in alphabetical order) to find out! 


1. Asus ROG Phone 5

Display: 6.78in; 1,080 x 2,448; AMOLED; 144Hz

System on chip (SoC): Qualcomm SM8350 Snapdragon 888 5G

RAM: 8-16GB 

Storage: 128-256GB 

Battery: 6,000 mAh


Asus, a well-known manufacturer of computer hardware, launched its first ROG smartphone in 2018. The ROG Phone 5, its latest entry, continues the legacy of these gamer-focused devices by offering excellent gaming performance, a high-refresh-rate screen for smoother gameplay, as well as a dedicated handset (the Kunai 3 gamepad is compatible with the ROG5), for those who prefer a traditional controller setup. With a whopping 6,000 mAh battery equipped with fast-charging capability, you’ll be able to play for hours without needing to worry about plugging in, and if you do need to top up the battery, doing so will be relatively quick.

However, you may want to think twice about this device if you’re concerned about the weight, as the ROG Phone 5 is a bit heavier than most; and unfortunately, it is a bit lacking in the camera department, at least compared to some other higher-end phones. 


2. iPhone 12 Pro Max

Display: 6.7in; 1,284 x 2,778; Super Retina XDR OLED; 60Hz 

SoC: Apple A14 Bionic


Storage: 128-512GB

Battery: 3,687 mAh


If you prefer Apple devices and are looking for a phone that you can play games on, unfortunately, Apple doesn’t sell a dedicated gaming phone. However, that doesn’t mean the iPhone 12 Pro Max isn’t up to the task of running high-end online games, and it will definitely be more than enough if you like casino games such as online roulette. Hardware reviewer AnandTech highlighted that the iPhone 12 Pro didn’t offer much more performance than its predecessor, the iPhone 11 Pro, but that the slight performance gains made on the graphics front put it in the lead. 

If you’re willing to pay the premium for this Apple flagship device, you’ll get a phone that offers you great performance, battery life, and undoubtedly one of the best cameras on the market.

3. Lenovo Legion Phone Duel 2

Display: 6.92in; 1,080 x 2,460; AMOLED; 144Hz

SoC: Qualcomm SM8350 Snapdragon 888 5G

RAM: 12-16GB 

Storage: 256-512GB

Battery: 5500 mAh


If you’re interested in a gaming phone with a unique look, you might want to take a look at the Lenovo Legion Phone Duel 2. The Duel 2 offers gamers some incredible specs that will let you play all kinds of games, including online scratch cards, for hours on end plus an interesting cooling system that forms part of the design of the back of the phone. It also has funky features, such as its forward-facing camera, which pops out of the side in portrait mode, or out of the “top”, if you’re holding it in landscape mode. This has been designed for gamers who like to livestream their sessions. It also has incredible dual 90W charging, meaning you’re able to recharge your phone quickly, on the off chance that the large 5,500 mAh battery is running low.

So if you’re a gamer with an interest in live streaming, be sure to check out the Duel 2. Other smartphone gamers may be slightly put off by the phone’s interesting, but niche approach to forward-facing cameras.


4. Xiaomi Black Shark 4 Pro

Display: 6.67in; 1,080 x 2,400; Super AMOLED; 144Hz

SoC: Qualcomm SM8350 Snapdragon 888 5G

RAM: 8-16GB

Storage: 256-512GB

Battery: 4,500 mAh


Xiaomi may not be the most popular smartphone brand, but it’s definitely become better known, thanks to the combination of high specs and affordability that it offers in its devices. The same is true of the Black Shark 4 Pro, which offers amazing value for money, especially when compared to some of the higher-end phones on this list. This phone offers great performance, shoulder buttons (think: smaller versions of what you would find on a PlayStation or Xbox controller), an incredible 120W charge speed, and great audio. 

The Black Shark 4 Pro may not have the best cameras, but if you’re looking for an affordable mobile gaming solution, you’re unlikely to regret picking up this phone.

5. ZTE nubia Red Magic 6

Display: 6.8”, 1080 x 2400, AMOLED, 165Hz

SoC: Qualcomm SM8350 Snapdragon 888 5G


Storage: 128-256GB

Battery: 5050 mAh


While some of us may be wondering what ZTE is, the company has actually been in the technology business since 1985, and is one of the largest mobile phone vendors in the world! To meet the demand for great gaming on the go, ZTE released the nubia range; and more recently, it has welcomed the Red Magic 6 into its product line. 

The first thing people are likely to notice is the phone screen’s blisteringly fast 165Hz refresh rate, which is the highest of the screens on our list. This allows the device to deliver buttery-smooth video, but does it have the performance to back it up? Thankfully, the answer is yes, and gamers will be able to enjoy high-end gaming performance thanks to the specs of this device. Just like the Black Shark series, this phone also has shoulder buttons, which gamers are bound to love.

Unfortunately, the Red Magic 6’s screen is a bit dull compared to some other models, and the battery life is average at best, but at least you can give it more juice reasonably quickly with its 66W-charging capability.
