Third-party reviews

What customers like about realme C100 5G

  • 144 Hz refresh rate makes scrolling look fluid.
  • 6.8 inch screen is large for video and reading.
  • 5G connectivity keeps you on faster mobile networks.
  • 128 GB of storage holds many photos, videos and apps.
  • NFC is built in for tap-to-pay and quick pairing.
  • UFS 2.2 storage helps apps open quicker.

What customers don't like about realme C100 5G

  • 4 GB of RAM means apps reload more often when you switch.
  • No optical image stabilization, so video shakes more when you walk.
  • No ultrawide rear camera for wide group shots.
  • No wireless charging, so you need a cable every time.
  • At 166.8 mm tall and 78.2 mm wide, it is a big phone to hold.

Verdict

Smooth scrolling is the surprise of the realme C100 5G, a budget phone with 5G, 128 GB of storage and a 144 Hz screen on 6.8 inches. Feeds and web pages move along nicely, and the IPS LCD suits films and reading. The 4 GB of RAM is the real limit here, so switching between many apps means some reload. At 254 ppi, small text looks soft when you read closely. The camera has no optical image stabilization and no ultrawide lens, and the body is big at 166.8 mm tall and 78.2 mm wide. It suits someone who mostly messages, streams and browses, and wants a big, fast screen on a budget. Heavy games are not its strength, but everyday apps run without much fuss.
