Samsung galaxy s25 ultra

Ignoring massive hardware changes year on year, Samsung focused on Galaxy AI in 2025. The new Galaxy S25 Ultra advances mobile A.I in general. 

The new S25 Ultra features cross app actions, allowing the use of a built-in digital assistant to communicate between apps on your galaxy. This feature applies to Samsung apps and Android apps, especially Google apps, Spotify, WhatApp, Google Maps and others. With a single command you can do multiple things, allowing you to look up info while chatting for example. 

The phone learns your habits and routines and creates what Samsung calls a "Now Brief" screen. This screen displays choice information on weather, calender evens and more. The feature learns as you use the phone over-time, growing in capacity with greater use of the Galaxy S25 Ultra.

The phone has  A.I apps tailored to Samsung. Circle to Search, Now Brief, Now Bar etc. These are similar but also quite different and better performing than iPhone's Live Activities platform.

Performance: The Snapdragon 8 Elite inside the Galaxy S25 Ultra does more than just help the new phone last longer on a charge. It also delivers some of the best performance we've seen on an Android device, especially since Samsung is using an overclocked version of the silicon. That helps the Galaxy S25 Ultra produce better benchmark numbers than the OnePlus 13, which also has a Snapdragon 8 Elite chipset. But the gaming-focused Asus ROG Phone 9 Pro can lay claim to the speed king title, thanks to its numbers on some tests. The neural engine on the Snapdragon 8 Elite coupled with 12GB of RAM on the base model give the Galaxy s25 Ultra enough processing muscle to handle more AI tasks on device. And the Galaxy S25 Ultra comes with a bigger, brighter display than last year's model so everything from gaming to streaming looks better on this new device. Verdict: The Galaxy S25 Ultra proves that big hardware changes aren't necessary to make a splash in the smartphone world. The Galaxy AI features debuting on this year's premium Samsung phone are reason enough to upgrade, especially if you've got an older phone. And the improved cameras, longer battery life and brighter screen add to the value, even if you find the Galaxy S25 Ultra's high price a little hard to swallow.

Camera: The Galaxy S25 Ultra presents an all new ultrawide sensor. The picture quality is upgraded to 50MP, allowing excellent detail and macros sharpness. There are upgrades to the ProVisual Engine. This processes photos excellently and adds to the brilliance of the camera of the Galaxy S25 Ultra. The S25 Ultra beats the iPhone 16 Pro Max, extensively in comparison, on many points of camera quality. Samsung's Galaxy S25 has excellent quick shots, selfie shots and shoots in low-light. It beats the iPhone 16 Pro Max in macro photos. With nice improvements to this model the Galaxy S25 Ultra becomes the best camera phone of 2025.

Battery/Power: The Battery on the S25 Ultra lasts longer than that of the s24. The stats show capacity for a little over 17 hours of online web browsing. The battery is supported by the Snapdragon 8 Elite chip which manages power use with ultra efficiency. In terms of charging it is very fast and supports Qi2 wireless charges. You may need a Qi2 adapted case in some cases because this model does not have a rear magnet.

Price and value: The Galaxy costs more than the competition at $1,299, this means that it is $100 more expensive than similar main offerings by Google and Apple and even more expensive more moderate competition like OnePlus. This is still the same price point as the last S24 and so no price up from the last model is seen. Their Base model of the Galaxy S25 comes with a 256GB storage but more more can be had for a little more money. Samsung also offers some Galaxy S25 Ultra deals that can help you get the phone for less depending on where and how you buy so ask questions.
