Samsung Galaxy S23 Ultra Review, An Epic Return

I have been using a Galaxy S22 Ultra since its launch last year. It’s one of the Android devices that I always carry with me every time I travel as it has all the features I need to connect with friends, take amazing photos, and play some games.

I must confess that though that the Galaxy S22 Ultra, while being an amazing device, isn’t perfect and it’s my least choice especially in terms of playing mobile games. I end up playing games on my ASUS ROG Phone 6, especially when it comes to FPS titles like Call of Duty Mobile and PUBG.

One year later, as expected, Samsung launched the Galaxy S23 Ultra. It is much better than I expected. In fact, it is so good, I had to renew my Smart plan bundled with Galaxy S23 Ultra to receive pre-order benefits that include a free memory upgrade and a few discount vouchers.

This review will cover all the phone’s essential features from design to battery performance. As usual, I will point out the positive and negative things about the device, and let you know if it’s a good purchase. Yes, the title is a dead-giveaway, but I must say that this phone isn’t exactly for everyone because of several points that are written on this review.

Design – Old but New

The Galaxy S23 Ultra features a recycled design with subtle changes. These subtle changes, however, have major impact on the device’s overall feel. The less curved corners give it more grip compared to its predecessor. Accidental input on both sides is almost eliminated, and that’s a huge change especially when compared to my experience with the Galaxy S22 ultra. The camera module on the back is a standout feature, with its bold design but familiar layout. I’ll talk about cameras in a little bit.

One of the most notable design features of the Galaxy S23 Ultra is its expansive display. The phone boasts a massive, edge-to-edge screen that provides an immersive viewing experience for everything from video content to mobile gaming. The screen is also protected by Corning Gorilla Glass Victus 2, which offers improved durability and scratch resistance compared to previous generations.

The Galaxy S23 Ultra’s design also incorporates a range of practical features that enhance the user experience. For example, the phone’s power button and volume rocker are thoughtfully placed and easily accessible, ensuring that users can quickly adjust settings and power the phone on or off as needed. Additionally, the phone’s USB-C port and headphone jack are both located on the bottom of the device, making it easy to charge and listen to music at the same time. Of course, the mighty S-Pen returns with better precision and performance. These small but impactful design choices demonstrate Samsung’s commitment to creating a smartphone that is both stylish and functional.

Performance and Power

The Samsung Galaxy S23 Ultra is a true powerhouse when it comes to performance. With its latest Qualcomm Snapdragon 8 Gen 2 and 12GB of RAM, the device can handle just about any task you throw at it with ease. Multitasking is a breeze, and apps launch in the blink of an eye. The device’s processor is lightning fast, and it handles even the most demanding tasks with ease. Whether you’re a power user who needs a device that can handle multiple applications running simultaneously, or you’re just someone who wants a fast and responsive device, the Galaxy S23 Ultra won’t disappoint.

It is also worth noting that the phone is using a slightly tweaked version of the Qualcomm Snapdragon 8 Gen 2. Unlike the OnePlus 11 that we reviewed, the Galaxy S23 Ultra has slightly higher frequencies to boot, and can deliver more power when needed. Unfortunately, it comes with the cost of having higher thermals overall. Based on my FLIR test, the Galaxy S23 Ultra sometimes reaches 40C-42C when playing games like Tower of Fantasy and Genshin Impact at Maximum Settings. This is totally understandable, but when you’re a gamer, I highly recommend that you invest on a case, cooler or third-party controller so you can play comfortably.

The tool generates an overall score based on the device’s performance in different tests, including CPU and GPU tests, RAM and storage tests, and user experience tests.

The Antutu Benchmark score is commonly used to compare the performance of different mobile devices and to identify the strengths and weaknesses of a particular device. Higher scores generally indicate better performance, but it’s important to note that the benchmark score is just one factor to consider when evaluating a device’s overall performance.

Camera Performance

The Samsung Galaxy S23 Ultra’s camera performance is a force to be reckoned with. It’s equipped with a quad-camera system that takes your photos to the next level. The new 200MP primary sensor captures the most stunning and detailed images, with fantastic color accuracy, dynamic range, and sharpness. The telephoto lens can zoom up to 10x optical zoom, allowing you to get close to your subject without sacrificing image quality. The wide-angle lens is perfect for capturing landscapes or large groups of people, while the macro lens is great for close-up shots of flowers or insects.


One of the most notable features of the Galaxy S23 Ultra’s camera is its ability to capture up to 8K30p video. With 8K video recording capabilities, you can take stunning videos that are incredibly detailed and clear. The device’s image stabilization technology ensures that your videos are smooth and steady, even if you’re moving around. You can also take advantage of the slow-motion video feature, which allows you to capture moments in slow motion, giving you a unique perspective on the action. There are also dedicated portrait and pro video features built in its camera applications. This gives me additional shooting options, including the ability to choose omnidirectional, front or back microphones, which are very handy when shooting vlogs, interviews, or YouTube videos.


The Galaxy S23 Ultra’s camera performance is further enhanced by its advanced AI-powered features. The device’s camera app is designed to make taking photos and videos as easy as possible. With features like Scene Optimizer, the camera can automatically adjust settings based on the subject, making it easy to get the perfect shot every time. The camera app also includes a range of fun and creative features like AR Emoji, which lets you create your own personalized emoji, and Single Take, which captures multiple photos and videos with a single press of the shutter button.

When shooting photos, you will experience a long shutter lag. This can be fixed by downloading Camera Assistant to help increase the speed of processing the photo from the time the shutter button was clicked. This would not have been possible without downloading this fix from Galaxy Store.

Battery Performance

The device is equipped with a 5,000 mAh battery, which the same compared the previous version. Despite this, the Galaxy S23 Ultra lasts longer than its previous generations, based on my experience. You can enjoy your favorite apps, stream your favorite movies, and listen to your favorite music without worrying about running out of battery. In fact, I only needed to charge my phone once every 42 hours as it can usually last for more than 18 hours in a single charge after a week of usage. I needed to give it some time to learn my usage habits so its AI can tweak its settings on the fly, thereby saving battery life.

It has a built-in power saver mode that reduces battery consumption by limiting the performance of some features. Moreover, it has an adaptive battery feature that learns your usage patterns and optimizes battery life accordingly. With these features, you can enjoy your device for longer periods without worrying about running out of juice.

One of the best things about the Galaxy S23 Ultra’s battery performance is that it supports fast charging. The device can be charged from 0 to 100% in less than an hour, which is a significant improvement over previous models. Additionally, the device supports wireless charging, so you can charge it without having to plug it in, making it even more convenient to use.
