Critic consensus
“The Zenfone 12 Ultra is very much an iterative update. Not a lot has changed since the Zenfone 11 generation. Asus is really not pushing the envelope in any way. We do appreciate the new Snapdragon 8 Elite chipset and the noticeable upgrade in burst performance, but the chip thermal-throttles quite aggressively under prolonged loads. Plus, the new chipset has taken its toll on battery life at least a bit. Another thing that shouldn't go unnoticed is the huge infusion of AI smarts and features in the Zenfone 12 Ultra.”
“The Asus Zenfone 12 Ultra isn't that bad of a phone. It looks a little dull, but that's likely preferable to the gamer aesthetic of the ROG Phone. When you compare the Zenfone and its price to Samsung and Google, it's hard not to notice what you're giving up to support a non-mainstream smartphone brand. The amount of support isn't good enough, and sharing too many features with the ROG Phone line only helps keep costs down while diminishing what makes each release unique.”
“The Asus Zenfone 12 Ultra is a powerful, high-spec phone with a large RAM capacity and a cutting-edge chipset. However, it doesn’t do enough to justify its high price, with no novel or useful extra features to help it compete with big-name rivals. The lack of notable upgrades over its predecessor doesn't help, either.”
“I've always enjoyed using ASUS's phones, and the Zenfone 12 Ultra is no different. It has the best-tuned software package of any Android phone, and the interface is fluid like nothing else available today. The UI itself is clean and uncluttered, and you don't get any bloatware either. It's a similar situation with the hardware, the phone leverages the latest Qualcomm silicon and is a gaming powerhouse, and the battery lasts all day with ease. As much as I like the phone, I can't recommend it — the cameras just aren't good enough for what it costs (€1,099), and ASUS's insistence on delivering just two Android platform updates is a deal-breaker.”
In Depth
Design
The Zenfone 12 Ultra presents a minimalist design that appeals to those who prefer a sleek look. Reviewers at TechRadar were impressed by the “smooth and porcelain-like” feel of the back, of which showcases the logo and a uniquely framed camera bump, lending an elegant touch.
ASUS’s design choices emphasize practicality and durability, with Gorilla Glass Victus 2 for screen protection and a 100% recycled aluminum frame. The phone’s matte-textured back avoids fingerprints and adds a subtle sophistication to its overall appearance, making it a top choice for style-conscious users.
Display(s)
The 6.78-inch AMOLED screen delivers sharp images and vibrant colors, enhancing your gaming and streaming experiences. With FHD+ resolution, it maintains clarity without overloading the visual details.
The adaptive refresh rate reaches up to 144Hz during gaming, offering buttery-smooth performance. In everyday use, it settles at 120Hz, making interactions feel seamless. Reviewers observed that the display excels in bright conditions but can appear slightly dimmer than some competitors.
While the display doesn’t hit the peak brightness levels of some flagship rivals, it’s consistent and reliable for most lighting conditions, ensuring you’re never left squinting on sunny days.
Performance
The Zenfone 12 Ultra performs well with its Snapdragon 8 Elite processor and 16GB of RAM, making gaming and everyday tasks smooth and responsive. However, as “experts pointed out, the performance scores trail behind the competition, especially in graphics-heavy applications.”
During typical use, you’ll experience fast app launches and seamless task switching, which enhances everyday usage. Unfortunately, the performance doesn’t reach the top benchmarks set by phones using the same chip, which might be a concern if top-tier phone gaming or demanding apps are your priority.
Software & Storage
The Zenfone 12 Ultra provides a nearly stock Android 15 experience. Choose between stock Android and ASUS’s version for a personalized touch.
Common AI features include translation and article summarization, all running on-device for added privacy, but setup requires a bulky download.
With just two years of OS updates promised, it lacks the extended support rivals often provide, making future device longevity a concern.
Cameras
While the camera boasts excellent stabilization due to its gimbal technology, it struggles in producing vibrant photos in various lighting conditions, often appearing dimmer and less colorful than alternatives. Android Authority notes the hardware remained unchanged, offering no major improvements from the previous model.
The consistency between the three lenses, including a 50MP main sensor, aims for versatility but sometimes lacks the dynamic range needed for stunning shots in challenging scenarios. The video capabilities impress with stability, compensating for some of the minor flaws noted in still photography.
With a competitive market offering more advanced camera systems at similar price points, reviewers emphasize the importance of balancing stabilization strengths against the need for richer color outputs on the Zenfone 12 Ultra.
Battery
The Zenfone 12 Ultra provides impressive battery life, courtesy of a 5,500mAh battery that supports extended daily use without worry. With moderate use, you’ll often see the battery lasting well into the next day, offering relief from the frequent charger hunt.
Charging won’t keep you tethered for long, thanks to the 65W wired capability that delivers a full charge in under an hour. As reviewers highlighted, “Using a ROG Phone charger, the Zenfone 12 filled to 42% in 15 minutes,” showing how it supports swift top-ups that keep your life moving.
While it doesn’t top the leaderboards for charging speed, its combination of longevity and quick top-off ensures it meets the demands of active, on-the-go lifestyles. This blend of battery prowess offers peace of mind when you’re away from power outlets.
Audio
You’ll enjoy clear and powerful audio whether you’re gaming or watching movies, thanks to the Zenfone 12 Ultra’s large stereo speakers and the inclusion of a headphone jack. This adds a unique layer of versatility not often found in high-end phones these days.
Experts have noted the “loud and meaty speakers” which elevate your audio experience with crisp sound and satisfying depth. Whether it’s blasting music or capturing the subtle details in a film, these speakers get the job done impressively.
For calls, the phone’s microphones and audio enhancements aim to deliver clear conversations, even in busy environments. This makes catching every word hassle-free, whether you’re chatting with friends or instructing voice assistants. Overall, the Zenfone 12 Ultra’s approach to audio sets it apart, offering a feature set that appeals both to the audiophile and the everyday user.
The Bottom Line
This device provides a solid performance with its powerful processor and long-lasting battery, making it suitable for gaming and everyday tasks. However, the camera system lacks refinement, leading to less vibrant and detailed images compared to rivals. Despite its performance, the phone’s value is marred by limited software support, only promising two OS updates. “The Asus Zenfone 12 Ultra is a good phone; it performs well, offers AI features, sports a decent trio of cameras, and has an elegant design,” stated one reviewer.
