Third-party reviews

What customers like about realme C100x

  • 256 GB of storage holds a large library of photos and videos.
  • The 6.8-inch screen runs at 120 Hz for smooth scrolling.
  • 5G connectivity is included for fast mobile data.
  • NFC works for contactless payments and quick pairing.
  • HDR mode helps the camera balance bright skies and dark shadows.
  • Notification controls let you decide which alerts get through.

What customers don't like about realme C100x

  • 4 GB of RAM can slow down when many apps stay open.
  • The 1.8 GHz boost clock and 12 nm chip make heavy games and editing feel slow.
  • At 78.2 mm wide and 166.5 mm tall, it is awkward to use with one hand.
  • No optical image stabilization, so handheld video shakes more.
  • No ultrawide camera for wide landscapes or group shots.

Verdict

256 GB of storage and a 6.8-inch screen at 120 Hz make the realme C100x a sensible pick for someone who keeps lots of photos, videos and apps on a phone. The screen is large and smooth, so video and reading feel comfortable. There is 4 GB of RAM and a chip built on a 12 nm process with a 1.8 GHz boost clock, so heavy games and many open apps will slow it down. The screen has 254 ppi, so text looks less sharp than on denser displays. The body measures 78.2 mm wide and 166.5 mm tall, which makes one-handed use harder. There is no optical image stabilization and no ultrawide camera either. It suits a buyer who wants space and a big screen for everyday use and does not mind a slower phone.
