Google Pixel 6 Pro
The Google Pixel 6 Pro's unique design, great software additions, superb camera quality and solid all-around performance have already earned the phone an excellent rating in our full review. With performance that's every bit as good as its design, it's the best phone Google has ever made. The main camera is on par with the best iPhones.
Apple iPhone 13
The standard iPhone 13 is a reliable choice for most people, sporting a 6.1-inch screen and two excellent rear cameras. For this model, Apple has pledged longer battery life, improved cameras and better durability than the Apple iPhone 12.
OnePlus 9
While OnePlus isn't as well-known as Apple or Samsung, the OnePlus 9 offers great performance at a relatively more affordable price than rivals. It's 5G-enabled, runs a powerful Qualcomm processor and has a decent camera for the money. It's a solid budget phone option if the lofty prices of the Galaxy S21 Ultra are out of your reach.
Google Pixel 6
With a starting price of $599, Google's Pixel 6 is the best Android phone you can get for the money. In terms of design, power, features and performance, the Pixel 6 is a big step up from its predecessor, the Pixel 5. Google's latest and greatest offers improved cameras, Android 12 and the company's in-house Tensor chip.
Google Pixel 5a with 5G

How many inches should a phone be?
Those who want to use a phone comfortably with one hand will likely prefer a phone under 5 inches. Next up is the camera. Budget phones will typically feature one or two lenses, but that's starting to change. The megapixel count doesn't matter that much; pay more attention to the capabilities of the camera.
How much does a stylus cost for a Motorola phone?
The Moto G Stylus costs $299 and there's a handy stylus tucked right into the bottom right corner of the phone. While you won't get S Pen levels of functionality, you will be able to remove the stylus and start jotting down notes on the Motorola phone's screen, all without having to unlock your device.
How much is the Pixel 5A cheaper than the iPhone SE?
It has one of the best cameras you'll find on any phone, and at $349, it's $50 cheaper than the iPhone SE. A newer Pixel 5a is reportedly on the way, but its release date is uncertain. If you want a 5G phone for less than $300, we recommend the TCL 10 5G or OnePlus Nord N200. They're both remarkable values.
How much is the iPhone SE 2020?
The iPhone SE 2020 is what happens when you make a cheap phone that isn't cheap. For $399, this iPhone offers the same fast performance as the iPhone 11 and iPhone 11 Pro, thanks to is A13 Bionic processor. And that same chip gives the iPhone SE photography capabilities that most budget Android phones lack.
Is the Moto G Stylus the same as the Moto G Power?
In many ways, the Moto G Stylus is exactly like last year's edition of the Moto G Power. They've got the same screen size and processor, though the G Stylus comes with more storage and a bigger main camera sensor. The biggest tradeoff, though, is battery, where the Moto G Stylus makes do with a 4,000 mAh power pack.
