Editorial report
Realme C100x 4 GB / 128 GB / Global technical sheet
The Realme C100x suits buyers who prioritize a very large battery and clear body protection over performance and display detail. Its main trade-off is speed: the configuration shown pairs 4 GB RAM with eMMC 5.1 storage and an AnTuTu score of 308,681, leaving its hardware among the weakest of its time.
Its 8000 mAh battery has more capacity than most phones of its time. It also supports 45 W fast charging, reverse charging and 90 h of endurance per cycle. IP64 covers water and dust resistance, while MIL-STD-810H covers shocks and drops. The phone is sold in 4 GB / 128 GB and 4 GB / 256 GB configurations; this version is 4 GB / 128 GB and supports expandable storage.
The 6.8″ IPS LCD display reaches 120 Hz and 900 nits, but its 254 ppi is among the weakest pixel densities of its time. The 50 MP rear camera has an f/1.8 aperture but no optical stabilization, and the camera setup is worse than most phones of its time. NFC, USB Type-C, Bluetooth 5.2, dual SIM and GPS are included, yet connectivity overall is worse than most phones of its time. With an overall NeoScore of 4.8, the Realme C100x is mainly a battery-and-protection choice, not a strong pick for performance, display detail or photography.
