durability

IP64 rating, splash-resistant onlySurvives accidental splashes and light rain, but cannot be submerged; avoid using near pools or in heavy downpours.

connectivity

GoSolo Verdict

The Infinix Note 50X 5G+ is a large-screen 5G phone aimed squarely at emerging markets, delivering solid battery life and 120Hz scrolling at a price that undercuts most rivals by a big margin. Its weak display resolution, modest cameras, and splash-only water rating mean it trades refinement for reach—fine if you prioritize screen size and 5G access over image quality or peace of mind in bad weather.

Strengths · 4

5500 mAh battery and 45W charging give a full day comfortably and a 60–75 minute top-up, a real advantage in markets where outlets are scarce
6.67-inch 120Hz IPS display is large and smooth for video and scrolling, with 560 nits brightness sufficient for most indoor and outdoor use
Dimensity 7300 Ultra handles everyday apps, streaming, and casual gaming without strain; dual SIM and 5G bands cover most major networks in emerging regions
8 mm body thickness and 195 g weight make it feel light and pocket-friendly despite the large screen

Trade-offs · 3

720p resolution on a 6.67-inch screen yields only 263 ppi—text and icons look soft compared to any modern phone at this price, and the 20:9 ratio exacerbates the awkward width
50MP main camera is let down by modest optics and no telephoto, ultrawide, or macro; video maxes at 4K 30fps, which lags rivals who now offer 60fps as standard
IP64 rating means splash resistance only—no submersion protection, so avoid pools or heavy rain, a real limitation in tropical climates where this phone will sell
