Asus Zenfone 11 Ultra Review


The Asus Zenfone 11 Ultra is a curious case. It boasts impressive specs and features, yet it leaves you wondering exactly who it’s for. Unlike some phones that struggle with usability or strange gimmicks, the Zenfone 11 Ultra is simply hard to place within Asus’s lineup and the wider market.

Part of the confusion stems from its name. The “11 Ultra” moniker suggests it’s a follow-up to the Zenfone 10, but its design borrows heavily from the ROG Phone line. Additionally, while the feature set is undeniably powerful, it doesn’t offer a clear value proposition compared to established flagships.

So, is the Zenfone 11 Ultra worth your money? It depends. If you crave a phone with top-of-the-line specs, a fantastic display, and a versatile camera system, it’s certainly a contender. However, if brand identity and a clear differentiation from competitors are important to you, you might want to explore other options before making a decision.

The Asus Zenfone 11 Ultra throws its hat into the crowded flagship phone ring, boasting a powerful processor, a stunning display, and a camera system that’s hard to ignore. But with so many contenders, how does the Zenfone 11 Ultra stack up?

Under the hood, the Zenfone 11 Ultra packs the latest Qualcomm Snapdragon 8 Gen 3 chipset, offering top-notch performance for even the most demanding tasks. With options of 12GB or 16GB of RAM and 256GB or 512GB of storage, you won’t have to worry about running out of space or slowing down.

Asus has nailed smartphone software, providing a generally clean and logical interface over the top of Android and offering a few subtle enhancements — for example, an alternative volume menu, a split Quick Settings view, and a different look to the incoming call screen — that can be manually activated if you want them. It’s all built around Android 14 on the Zenfone 11 Ultra, and the general software use is one of the best parts of the phone. It’s not exciting, but you buy the ROG Phone 8 Pro if you want the option of a flashy interface as well.

But wait, there is some AI to jazz it up! In what is rapidly becoming one of the least interesting “feature” sets on 2024 phones, AI modes like AI Transcript, AI Noise Reduction, and AI Call Translator are all onboard for your enjoyment. The noise reduction for calls seems to work well, and I’ve left it active throughout my time with the phone, but I have not found any use for the other features yet. This is a problem with AI on other phones and not exclusive to the Zenfone 11 Ultra.


The Zenfone 11 Ultra boasts a versatile triple-camera system on the back. The main 50MP sensor with gimbal stabilization promises sharp and steady photos and videos.

A 32MP telephoto lens provides 3x optical zoom, while a 13MP ultrawide sensor captures expansive shots. The 32MP front-facing camera ensures high-quality selfies and video calls.

Don’t write it off, though. The Zenfone 11 Ultra takes good photos, and while it’s not going to take any grand prizes, it won’t disappoint you when you use it. Photos can be fun and vibrant, white balance is effective, and the gimbal seems to help with lowlight images as nighttime photos are balanced and sharp. Look closely, and you can see noise and haloing. Switching between the main and wide-angle camera shows there isn’t much consistency, with the wide shots being far more saturated than the main camera.


The 5500mAh battery keeps the phone going all day long, even with heavy use. When it’s time to recharge, the 65W fast charging gets you back to 100% in under 40 minutes. The phone also supports 15W wireless charging and 10W reverse wired charging for powering up your other devices.


Android 14” refers to the software that the Asus Zenfone 11 Ultra runs. In this case, the phone operates on the Android 14 operating system.

Android is a mobile operating system developed by Google. It’s the most widely used operating system for smartphones and tablets globally.

Unboxing the Asus Zenfone 11 Ultra

The Asus Zenfone 11 Ultra arrives in an eco-friendly cardboard box, ditching unnecessary packaging. Here’s a glimpse of what you’ll find inside:

  • Minimalist Packaging: Asus prioritizes eco-friendliness with a cardboard box.
  • SIM Tool and Case: A SIM card ejector tool is included for easy setup. You’ll also find a basic case to protect your phone from scratches and bumps.
  • The Star of the Show: The Asus Zenfone 11 Ultra itself will be nestled securely within the packaging.
  • Charging Cable: A USB Type-C cable is included for connecting to your computer or a power adapter (not included).

Missing But Not Forgotten

One notable absence in the box is a power adapter. Asus has joined the trend of some manufacturers in excluding chargers to reduce waste. You’ll need to provide your own charger or purchase one separately.

The Verdict

The Asus Zenfone 11 Ultra is a compelling option for users looking for a powerful and feature-rich phone with a long-lasting battery. The stunning display, excellent camera system, and clean software experience are all major selling points. However, the lack of a charger in the box and potential thermal throttling issues are drawbacks to consider. If these aren’t dealbreakers, the Zenfone 11 Ultra is a strong contender in the flagship phone market.
