If you prioritize a lower-cost device with a larger battery life, the Motorola One 5G Ace could be suitable, though you would compromise on camera quality and screen display, as it has a lower-quality LCD screen and camera compared to the Samsung Galaxy S21+. The Samsung Galaxy S21+ offers a higher-quality OLED display, superior camera performance, and more advanced features like an under-display fingerprint sensor and wireless charging, at the cost of being more expensive and somewhat shorter battery life. Both phones operate on Android and support 5G, but if camera and screen quality are important to you, the Galaxy S21+ would be the better option despite its higher price. Give Feedback

Mark Knapp | February 2021
"The Motorola One 5G Ace is on the affordable side, but you don’t get a phone that will expire quickly. It proves plenty speedy for most uses, and has 5G support to get you onto the latest cellular technology. With a 6.7-inch display, the Motorola One 5G Ace is about as big as they come. The display is plenty bright, as sharp as it needs to be, and even offers HDR to round out the package."

"All told, Samsung nailed it with the Galaxy S21 Plus. It has most of the strengths of the smaller S21 in a bigger package. It’s got a lot going for it. If you’re coming from an older device, like the Galaxy S10 series, this is a solid upgrade."
