Charger in the box
The Europe specification page’s in-box list does not include a charger, while realme’s Europe product page says a 15 W charger is in the box. The Singapore specification page lists a charger but does not state its wattage. Package contents therefore need to be checked against the local retailer’s exact box listing.
Display and cameras
The 6.8-inch LCD has a 1570 × 720 resolution and a maximum refresh rate of 144 Hz. realme lists typical brightness of 700 nits and HBM brightness of 900 nits. The rear camera is 50 MP with an f/1.8 aperture and autofocus; the front camera is 5 MP with an f/2.2 aperture. The specification page lists digital zoom up to 10× and no optical zoom. These numbers describe hardware and supported modes, not independently verified image quality.
realme also warns that screen protectors with poor light transmission—such as colored or darkened ones—may block the light-sensor opening and affect normal phone use. If applying a protector, choose one that leaves the sensor unobstructed.

Charging and battery-life claims
The phone supports charging up to 45 W. realme says reaching maximum charging power requires its 45 W charger and original cable; charging power varies with the scenario. Check what comes with the regional retail package before buying a separate adapter.
For the 6,600 mAh battery version, realme publishes estimates of 17.2 hours of navigation, 135.7 hours of music playback and 18.3 hours of online video. These are manufacturer test figures, not independent measurements, and realme says actual battery life depends on usage conditions. They should not be treated as guaranteed runtimes for other regional battery versions.

realme’s Europe product page describes IP64 dust and water resistance and MIL-STD 810H shock-resistance testing. These are manufacturer claims, not a promise that the phone is waterproof or immune to damage. The same page projects six years of battery health based on realme Lab testing and stated assumptions; it is not a guarantee of each user’s battery condition or a warranty.
