Comparison: Zenfone 12 Ultra vs Competitors
When comparing the Asus Zenfone 12 Ultra with other flagship smartphones like the Samsung Galaxy S24 Ultra and iPhone 15 Pro Max, the Zenfone makes a compelling case in several key areas. Starting with the display, it features a large 6.78-inch AMOLED panel with a 144Hz refresh rate, offering a smoother visual experience than both the S24 Ultra’s 120Hz Dynamic AMOLED display and the iPhone’s 120Hz Super Retina XDR screen.
In terms of performance, the Zenfone 12 Ultra is powered by the latest Snapdragon 8 Gen 3 processor, which it shares with the Galaxy S24 Ultra. However, Asus pushes further with up to 16GB RAM and 512GB storage, making it ideal for multitasking and gaming. Apple’s iPhone 15 Pro Max, on the other hand, runs on the A17 Pro chip with 8GB RAM, optimized more for stability than raw performance.
For photography lovers, the Zenfone offers a 200MP triple camera setup with OIS, delivering sharp, vibrant shots. This matches closely with Samsung’s 200MP quad camera system, while the iPhone lags slightly with a 48MP setup. Battery life is another area where Asus takes the lead — its 5500mAh battery with 65W fast charging outpaces Samsung’s 5000mAh (45W) and Apple’s 4422mAh battery that supports only 25W wired charging.
On the software side, the Zenfone 12 Ultra runs Android 14 with Zen UI, providing a clean, customizable user interface. This compares well with Samsung’s One UI and Apple’s iOS 17, although each has its unique ecosystem advantages. Finally, the pricing gives Asus an edge. While the Galaxy S24 Ultra and iPhone 15 Pro Max are priced well above ₹1,20,000, the Zenfone 12 Ultra is expected to launch at ₹84,999, offering flagship specs at a more affordable price point.
