Motorola Edge vs Samsung Galaxy S21 Ultra

The Galaxy S21 Ultra is the better camera phone and the better long-term buy for most people. Its 108 MP main sensor, 10x optical zoom and 100x Space Zoom beat the Edge's triple camera, and its 1440p Dynamic AMOLED 2X screen is sharper than the Edge's 1080p panel. The Edge wins on newer software, 256 GB storage, 12 GB RAM, a 50 MP selfie camera and 68W wired charging. Buy the Edge if you want a new, current phone with more storage and faster charging. Buy the S21 Ultra if photography and screen quality matter most, and you accept a refurbished unit with 128 GB and no charger in the box.

  • Choose the Motorola Edge if you want a new, current phone with 256 GB storage, a 50 MP selfie camera and fast 68W charging.
  • Choose the Samsung Galaxy S21 Ultra if camera reach, a sharper 1440p display and Samsung's longer software support matter more than storage.

What reviewers say

Motorola Edge

  • 4 / 5140 ratings

Rated 4 out of 5 from 140 ratings. Buyers generally like the large 120Hz OLED screen and the camera setup for the price; some flag the single-SIM setup and carrier compatibility as the main drawbacks.

What people mention
  • DisplayPraisedOwners call the 6.7-inch 120Hz P-OLED smooth and bright for video and scrolling.
  • CamerasPraisedThe 50 MP main sensor and telephoto lens get credit for versatility at this price.
  • BatteryPraisedThe 5200mAh cell plus 68W charging is described as lasting a full day with quick top-ups.
  • Carrier supportCriticisedBuyers note the GSM-only international version will not work on CDMA-first networks.

Samsung Galaxy S21 Ultra

  • 4.7 / 56,796 ratings

Owners rate the S21 Ultra highly for its screen, cameras and battery, and many still consider it a strong used flagship. Complaints center on size, weight and the loss of microSD expansion.

What people mention
  • DisplayPraisedOwners call the 120 Hz Quad HD+ AMOLED screen bright, sharp and smooth.
  • CamerasPraisedThe 108 MP main camera and zoom range are widely praised for detail and versatility.
  • BatteryPraisedThe 5,000 mAh battery generally lasts a full day of mixed use.
  • SizeCriticisedMany find the 6.8-inch body heavy and awkward to use one-handed.

Questions and answers

Which has the better camera?
The Galaxy S21 Ultra. Its 108 MP main sensor and 10x optical zoom give far more reach and detail than the Edge's 50 MP triple camera. The Edge wins on selfies with its 50 MP front camera.
Which is better for battery life?
The Edge has a 5200 mAh battery and 68W charging, so it tops up faster. The S21 Ultra's 5000 mAh cell is close, and its adaptive 10-120Hz display helps it last. Both get through a full day for most users.
Is the S21 Ultra worth stepping up to over the Edge?
Yes if camera zoom and screen sharpness are your priorities. The S21 Ultra's 1440p display and 10x optical zoom are a clear step up. The Edge is the better pick if you want new condition, more storage and faster charging.
Which lasts longer?
The Edge is newer and gets Android updates longer. The S21 Ultra is older and its update window is closing, though its IP68 rating and Gorilla Glass Victus make it the more durable body.
Does the S21 Ultra have a charger in the box?
No. Samsung stopped including chargers with the S21 series, so you need your own USB-C charger. The Motorola Edge ships with original accessories in the box.
Which is better for storage?
The Motorola Edge, with 256 GB against the S21 Ultra's 128 GB. Neither phone takes a microSD card, so the Edge gives you more room for photos and apps.
