NeoTeo's verdict
Which of the two is the better buy
The Realme C100x is the more complete choice for battery, charging, and camera priorities: its 8,000 mAh battery, 45 W charging, and 50 MP main camera surpass the C100i. The Realme C100i is preferable when 208 g matters more than 219 g.
Performance is closely matched because both use the Unisoc T7250 with eight cores, two Cortex-A75 cores at 1.8 GHz, and six Cortex-A55 cores at 1.6 GHz. The display glass differs: the C100x uses Panda Glass with Mohs Level 5 hardness, while the C100i uses Gorilla Glass.
The battery is the clearest separator: 8,000 mAh and 45 W on the C100x versus 7,000 mAh and 15 W on the C100i; only the first also offers reverse charging. For the main camera, the C100x combines 50 MP with f/1.8, compared with 8 MP and f/2 on the C100i.
