4. Buying Decision Framework

Here are three questions to consider:

  1. How important is display quality to me?

    • If it's critical, the Moto G31's AMOLED and higher resolution are the clear winners.
    • If it's not your top priority, the Nokia G21's display may be adequate.
  2. Do I need fast charging or a smoother visual experience?

    • If so, the Nokia G21’s 18W charging and 90Hz refresh rate will be appealing.
    • If these aren't crucial for you, the Moto G31 will do just fine.
  3. How important is camera versatility and quality?

    • If you want to take wide-angle photos, or enjoy slow motion video, the Moto G31 is a better bet.
    • If you are mainly focused on standard photos, either phone will perform well.

Scenario-Based Recommendations:

  • For the Media Enthusiast: Choose the Motorola Moto G31 for its superior AMOLED display and sharper visuals for media.
  • For the On-the-Go User: Choose the Nokia G21 for faster charging and smooth visuals while you use your phone.
  • For the Budget-Conscious Photographer: Choose the Motorola Moto G31 if you want wide-angle photography, or choose the Nokia G21 for a slightly sharper f/2.0 front camera.
  • For the Gamer: Choose the Motorola Moto G31, featuring a gyroscope and compass for an enhanced gaming experience.

My Personal Choice

If I were choosing between these two, I would lean towards the Motorola Moto G31. The AMOLED display with its higher resolution is just too significant of an advantage for me, especially with the added benefit of its wide angle camera and better audio. While the Nokia G21 offers slightly better performance and faster charging, the difference isn't enough for me to make the sacrifice of such a significant display downgrade, especially since my phone use mainly revolves around consuming media.
