Motorola Moto G Stylus vs Samsung Galaxy S21 Ultra 5G

The Galaxy S21 Ultra is the stronger phone: a sharper 1440p AMOLED screen, a far more capable camera system with 108MP main and 100x zoom, 12GB RAM, and a 5nm chip that still feels fast. The Moto G Stylus wins on the built-in stylus, a headphone jack, and a lighter, simpler Android experience. Buy the S21 Ultra for photography, gaming, and long-term use; buy the Moto G Stylus if you write or sketch by hand and want a headphone jack. Note the S21 Ultra is older and pre-owned units may have worn batteries, while the Moto is a budget 4G phone with only 4GB RAM in this listing.

  • Choose the Moto G Stylus if you want a built-in stylus for notes and sketching, a headphone jack, and a lighter phone for everyday tasks.
  • Choose the Galaxy S21 Ultra if camera quality, a sharper display, and more RAM for gaming and multitasking matter more than having a stylus.

  • Motorola Moto G Stylus: $84.00 at Walmart (last seen Nov 2)
  • Samsung Galaxy S21 Ultra 5G: $258.98 at Walmart (checked today)
  • Difference: the Motorola Moto G Stylus is $174.98 cheaper than the Samsung Galaxy S21 Ultra 5G at the latest prices (Nov 2 and Nov 9)

  • DisplayPraisedThe 120Hz pOLED screen is called bright and smooth for a budget phone.

Samsung Galaxy S21 Ultra 5G

  • 4.2 / 58,900 ratings

Questions and answers

Which is better for taking photos?
The Galaxy S21 Ultra. Its 108MP main sensor, OIS, and 100x zoom give far more reach and detail, especially in low light. The Moto G Stylus is fine for casual shots but trails on zoom and night photos.
Is the S21 Ultra worth stepping up to over the Moto G Stylus?
Yes if camera quality, display sharpness, and gaming performance matter to you. The S21 Ultra is a former flagship with 12GB RAM; the Moto is a budget phone with 4GB. Skip the step up only if you need a stylus or headphone jack.
Which lasts longer?
The S21 Ultra has stronger hardware and should stay usable longer, but it is an older model and pre-owned batteries may be worn. The Moto G Stylus is newer and its 5000mAh battery is rated over 40 hours, but 4GB RAM will feel tight sooner.
Does the Moto G Stylus work with 5G?
This listing is 4G only. The Galaxy S21 Ultra supports 5G, including mmWave on some versions.
Which is better for note-taking and drawing?
The Moto G Stylus, because the stylus is built in and stored in the phone. The S21 Ultra has no stylus support, so you would need a separate S Pen and a case that holds it.
