If you prioritize a better camera and longer battery life, the Apple iPhone 13 Pro Max is a solid choice, despite its higher cost. However, if saving money is important to you and you're comfortable with a phone that has generally good but not top-tier camera quality and slightly less battery life, the OnePlus 9 Pro offers significant savings. Both phones have a similar screen size and high refresh rate displays for smooth visuals, but the iPhone 13 Pro Max has a higher peak brightness which can be better for outdoor use. The OnePlus 9 Pro runs on Android, while the iPhone uses iOS, so consider which operating system you prefer as well. Give Feedback

Tom's Guide
Mark Spoonauer | March 2023
"The iPhone 13 Pro Max is that rare phone that gets a 5-star rating from us. You get blistering performance and a very responsive 120Hz display. Plus, the battery life is among the best we’ve seen from a 5G flagship. Some may simply prefer the iPhone 13 Pro because it’s smaller and lighter, as there are no other functional differences between the two handsets. But if you prefer a bigger screen, the iPhone 13 Pro Max is the closest thing to perfect you can get in a phone."

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.

OnePlus, established in 2013, is a smartphone brand that first became known for providing flagship-like devices, at a fraction of the cost compared to more expensive Android competitors. OnePlus focuses on creating smartphones with powerful hardware at reasonable prices. They also bring hardware features normally not seen in other Android phones sold in the US, such as their ultra-fast “Warp Charge” and the beloved “Alert Slider”.
