Mark Spoonauer | September 2021
"The iPhone 11 delivers superb cameras, fast performance and excellent battery life, making it the iPhone to buy for many people. The cameras are very good, thanks to an ultra-wide lens and a Night mode for better low-light performance. This device also has IP68-rated water resistance, which means that it can withstand 2 meters of water for 30 minutes, and is one of the best waterproof phones out there."

"The Asus Zenfone 9 is a compact device that still packs more than enough power under the hood. It's compact size, Bluetooth and audio features (including a headphone jack!), and hardware gestures combine to offer a package that does enough differently to warrant your attention."

About Apple
The tech giant called Apple is synonymous with the most popular smartphone in the world: the iPhone. Known for their build quality and aesthetics, as well as for their excellent integration between hardware and software, iPhones have defined the smartphone industry ever since their conception and they continue to do so by setting new industry standards. Apple's own operating system, called iOS, is known for its simplicity and ease of use, and the company tends to complement it well by creating devices with some of the most powerful processing hardware available in the mobile world. The iPhone is also known for its robust ecosystem of accessories, as it facilitates a very seamless experience when interacting with other Apple products, more so than most of its competitors.
About ASUS
Asus is a well-known player in the mobile world, and in the past few years it has been known for covering specific niches in the smartphone market. Their Zenfone line of devices appeal to small phone enthusiasts, by providing very well-rounded and capable phones at a package that is not too large to operate with one hand – something hard to find in modern Android smartphones. Conversely, their ROG line of devices cater to mobile gamers, by providing a slew of hardware and software features, specifically tailored to enhance the mobile gaming experience. Additionally, Asus is one of the only manufacturers left that continues to include headphone jacks in their lineup of phones, a feature that has become exceedingly rare in today's market.
