Editorial report

Realme 12x 12 GB / 256 GB / China technical sheet

The Realme 12x suits anyone looking for a slim, light phone with a large, smooth display; its main trade-off is a camera that falls behind most phones of its time. It is 7.7 mm thick and weighs 188 g. The 6.72-inch IPS LCD has a 1080 × 2400 px resolution, a 120 Hz refresh rate, and 950 nits peak brightness.

The configuration shown pairs 12 GB of RAM with 256 GB of expandable storage. The phone is also sold with 512 GB, so the range runs from 12 GB / 256 GB to 12 GB / 512 GB. The MediaTek Dimensity 6100+ and 5G connectivity round out the setup. It also has dual-band Wi-Fi, Bluetooth 5.3, a 3.5 mm audio jack, and USB-C. Android 14 is the operating system. Google Services are absent, which matters to anyone who relies on them.

The camera falls behind most phones of its time. The 50 MP rear main camera has no optical image stabilization and records video at 1080p at 30 fps. Its 5000 mAh battery and 45 W charging are typical figures for phones of its time, rather than a point of distinction. With an overall NeoScore of 5.5, the Realme 12x makes the most sense for buyers who put a slim build, low weight, and display ahead of camera strengths.
