12
across 5 reviews
4.1/5
Reviewers praise
  • Outstanding battery life from a large 5400mAh cell that delivers two full days of use in default settings, paired with 80-watt wired charging that reaches half capacity in twelve minutes and full charge in under thirty minutes
  • Bright, high-quality LTPO display reaching 1600 nits outdoors with excellent outdoor readability, support for both HDR10+ and Dolby Vision, and extremely dim low-brightness mode
  • Snapdragon 8 Gen 3 delivers smooth, fluid performance with improved cooling and noticeably snappier app launches and scrolling compared to some competing flagship chips
Reviewers push back
  • IP65 water resistance rating provides only splash protection, not full submersion protection like IP68-rated competitors, limiting use near water
  • Curved edge display causes light falloff, extra reflections, and occasional false touch inputs that frustrate some users
  • Camera performance shows inconsistent white balance with yellowish-greenish tinge in some conditions, and video footage can appear overexposed with average detail levels
Reviewers agree the OnePlus 12 delivers flagship performance, exceptional battery life, and extremely fast charging at a lower price than ultra-tier competitors, though it compromises on water resistance and camera consistency.
— best for: The OnePlus 12 suits users who prioritize battery endurance and charging speed over cutting-edge cameras and maximum water resistance, especially those seeking flagship performance without ultra-tier pricing.

Je suis vraiment satisfait de mon achat . Le robot cartographie votre maison lors de la première mise en route (il faut avoir une connexion WIFI ! ) toutes les fonctionnalités se font via un smartphone. Il aspire parfaitement (4 puissances différentes) il n'est pas bruyant du tout ! Je trouve que c'est un très bon rapport qualité/ prix ( Moins de 300 euros) Waluc · Cdiscount
