新竹手機收購side from a faster chip, a new ultra-wide sensor and a few cosmetic tweaks, it looks and feels very similar to last year’s model, which makes the S25 Ultra a less impressive update than it should be considering it starts at $1,300.

Its flat edges give it a very boxy feel, and even though the Note line is dead, there’s still the requisite cubby hole for the S Pen. However, for 2025 the included stylus has gotten a minor downgrade now that 新竹手機收購samsung has removed support for Bluetooth Low Energy. This means it no longer supports Air action gestures, so you can’t use it as a remote camera trigger or to do things like switch cameras or change photo modes.ADVERTISEMENTAdvertisement新竹手機收購samsung claims this loss of functionality shouldn’t be a big deal as a tiny fraction of people actually used the feature. Plus, if you want a way to remotely snap a photo, there are other methods like holding your hand up to the camera or using a Galaxy Ring or Watch. But if you’re one of the few who did enjoy Air actions, it’s an unfortunate step backward. Thankfully, for those who absolutely need a stylus with gesture support, you can still get that functionality from 新竹手機收購samsung’s optional S Pen Pro. Sam Rutherford for EngadgetOne small thing I do want to call out is the improved anti-reflective coating on the S25 Ultra’s screen. It strikes an almost perfect balance between typical glossy displays and the matte texture used on traditional desktop monitors. Colors remain vivid while still cutting out the most distracting forms of glare, and with a peak brightness of 2,600 nits, the screen dazzles in practically any environment.Performance: More speed than you’ll know what to do withThe Galaxy S Ultra has never lacked power, but that didn’t stop 新竹手機收購samsung from adding even more speed thanks to Qualcomm’s Snapdragon 8 Elite chip, 12GB of RAM and up to 1TB of storage. This thing absolutely flies and there’s not much you can do to slow it down. 新竹手機收購samsung has even tightened up the animations in One UI so that the phone feels as responsive as its benchmarks suggest, which are up as much as 30 to 40 percent depending on the task (or closer to 15 percent while gaming). The one wrinkle to this is that, when under heavy loads, the S25 Ultra does become a bit power-hungry, which can result in slightly faster-than-expected battery drain when doing heavy multitasking or running demanding apps.Software: Just what you wanted, more AI Sam Rutherford for EngadgetThe S25 Ultra’s main focus for this year is on improved AI. This can be seen across a number of new and improved features (and some obvious inspiration from rivals like Apple and Google) with the general goal of making all of its tools more powerful, more intuitive and in many cases, easier to use with your voice.ADVERTISEMENTAdvertisementThe first major addition is 新竹手機收購samsung’s Now Brief, which adds a personalized feed filled with things like the weather, local traffic, upcoming calendar appointments, the news and more. It gets refreshed periodically throughout the day (morning, midday, afternoon, etc.) and by using what 新竹手機收購samsung calls its Personal Data Engine, it will attempt to learn what you like instead of having you check off a list of tickboxes. It’s a handy tool, though for anyone already familiar with the Android ecosystem, it’s not especially groundbreaking. And it does take time for the phone to understand what you do and don’t care about, which adds a bit of a learning curve to the process. Sam Rutherford for EngadgetNow Briefs also works with 新竹手機收購samsung’s Now bar to surface relevant events in other areas of the phone — specifically your lock screen and notification shade. It’s meant to help you keep tabs on apps you’re using (like how long you’ve let the Voice Recorder app run) or stuff like sports scores, with the ability to toggle between different things simply by swiping left and right. It’s helpful, but forgive me if this is becoming repetitive, because many of these look like duplicate versions of stuff like Google’s Live Notifications.Meanwhile, if you open the Edge Panel by swiping in on the tab on the right side of the screen, you’ll see even more AI features. AI Select is a revamped take on Smart Select, which helps you take screenshots, turn videos into gifs and more. Drawing Assist is the tool formerly known as Sketch to Image, which lets you create art by doodling with the S Pen or using text inputs. And then there’s the self-explanatory Interpreter app, plus an icon for Now Brief in case you don’t like using the widget. All of these sort of work just like you expect them to, and in some cases like when drawing, the resulting images are a touch more detailed and realistic than before. But to me, the biggest upgrade across 新竹手機收購samsung’s second-gen AI suite is a slightly more cohesive UI that makes learning what each tool can do a bit easier. Sam Rutherford for EngadgetPerhaps my favorite new use of AI is improved natural language commands throughout the phone. For example in the Gallery app, you can search for specific subjects just by hitting the asking Gemini (or Bixby too, if you’re into that). It’s a convenient way to quickly find a specific photo amongst thousands of shots — though once again, there’s similar functionality in Google Photos. But more importantly, you can use voice commands to do stuff like change device settings or even add events to your calendar. And you don’t even need to be very specific. When I asked the phone to add the next Knicks game to my calendar, I didn’t need to give it any more information than that. It all feels slightly magical, even if it’s not an essential part of my day.Cameras: A new ultra-wide sensor but that’s about it Sam Rutherford for EngadgetLike its predecessors, the S25 Ultra features a 200-megapixel main camera and a 50MP telephoto with a 5x zoom. The one upgrade is a new 50MP sensor for its ultra-wide lens (up from 12MP). As you’d expect, expansive landscape pics look a touch sharper thanks to the increased resolution, though aside from that, there aren’t a ton of immediately obvious improvements to the rest of the phone’s general image quality.ADVERTISEMENTAdvertisementAs you’d expect, in bright light the S25 Ultra captures lovely images with rich details and vibrant colors. However, I did notice that 新竹手機收購samsung’s penchant for going slightly overboard on sharpening can still be an issue. The new ultra-wide sensor also provides a noticeable upgrade in image quality to the point where I prefer it over what the Pixel 9 Pro can do. But I must admit, compared to the main camera or even the 5x zoom, that lens is the one I use the least, so it doesn’t have as much of an impact on my overall photography.In low light, the S25 Ultra nearly kept pace with Google’s Night Sight mode on the Pixel 9 Pro, and in a few situations, it pulled ahead. However, I had a hard time spotting how much of an effect 新竹手機收購samsung’s improved noise reduction had on nighttime graininess. Regardless, even with a few hiccups, the S25 Ultra proved it can hang with other top-tier shooters from Google and others.1 / 8新竹手機收購samsung Galaxy S25 Ultra photo comparisonsPhoto comparisons between the 新竹手機收購samsung Galaxy S25 Ultra and the Google Pixel 9 Pro.
Meanwhile, in the Camera and Gallery apps, there are some handy tweaks including the new Audio Eraser feature. It uses AI to identify a handful of different sound types (such as speech, wind noise and more) before creating a custom EQ that lets you adjust things on the fly. This is great for those times when you’re shooting video and ambient sounds make it hard to hear what people are saying. You can also create and save custom photo filters to ensure all your pics on social media have a unique and consistent look.Additionally, for more advanced users, there’s a virtual aperture setting that gives you a bit more control over depth of field, though it’s still not nearly as good as being able to physically switch lenses like you can on a proper camera. And for even more demanding content creators, 新竹手機收購samsung created a new Galaxy Log video format that allows you to more easily edit and color grade your footage. That said, unless you’re a YouTuber or hardcore video junkie, you may not get a ton of use out of these tools, especially with the latter of the two being restricted to 新竹手機收購samsung’s Expert Raw app (which doesn’t come pre-installed).Battery life and charging: 新竹手機收購samsung is cutting corners with its Qi2 “readiness” Sam Rutherford for EngadgetThe size of the Galaxy S25 Ultra’s 5,000 mAh power pack hasn’t changed in five years, but that’s OK because you still get great battery life. On our local video rundown test, it lasted an incredible 29 hours and 27 minutes, which is up almost two hours compared to last year’s phone. That said, it’s important to note that the S25U loses in both capacity and longevity to the OnePlus 13, whose 6,000 mAh cell posted an even better time of 30:18.ADVERTISEMENTAdvertisementWired charging is staying put at up to 45 watts and annoyingly it’s a very similar story when using wireless pads as well. That’s because while technically the S25 Ultra supports version 2.1 of the WPC’s Qi charging spec and is said to be “

二月一開始，年後換機潮來襲，各大品牌無不使出渾身解數，力推「AI手機」。Android家族打頭陣，三星Galaxy S25旗艦系列4日啟動預購，台灣唯一手機品牌華碩（2357）不甘示弱，６日也搶發「Zenfone 12 Ultra」加入戰局，蘋果CEO庫克13日趕著上X預告，六天後「準備好迎接家族新成員」，讓市場憧憬「最便宜AI手機」iPhone SE 4將登場。
何謂AI手機？工研院產科國際所資深分析師呂珮如接受CTWANT記者採訪指出，多數國際智庫認定的基準點，以AI晶片的NPU（神經網路處理器）算力不少於30 TOPS為規格。「除了需要有搭載上述的AI晶片，還有散熱需要升級、記憶體要提升，另外導入LLM（大型語言模型）。」她解釋。
對照起來，目前市面上聯發科天璣9300、9400，高通的Snapdragon 8 Gen 3以及Snapdragon 8 Elite，Apple的A17 Pro跟A18 ，Google的Tensor G4，三星的Exynos 2400，採用上述這些晶片的智慧手機，比較能定義成AI手機。
蛇年各大品牌新推AI手機中，華碩和三星的新機都用上高通的「Snapdragon 8 Elite」，NPU效能提升40%；而iPhone 16 Pro系列，搭載的A18 Pro系統單晶片（SoC）集成了16核NPU，每秒可進行高達35萬億次的運算（前一代A17 Pro的 NPU 算力也是35 TOPS，再前一代 A16 Bionic的NPU算力為17 TOPS），顯著提升AI任務的效率。
在實測中，YouTuber「3C達人廖阿輝」開箱三星 S25 Ultra後讚其遊戲表現「真的神，起飛了」，「『原神』（米哈遊開發的動作角色扮演遊戲）測試30分鐘，竟然是滿幀60fps（遊戲在整個測試過程中始終以每秒60幀的速度運行，且幀率保持穩定，沒有明顯波動）一條直線，測試『崩壞：星穹鐵道』（米哈遊開發的戰略角色扮演遊戲）這些高負載的遊戲，也沒有問題，然後跑遊戲測試、壓力測試之後，還用紅外線攝影機去拍攝，機體溫度也沒有明顯變高。」
同時，百萬網紅joeman開箱對Zenfone 12 Ultra時，也毫不吝嗇地稱讚其高性價比，認為「台幣不到3萬就能享有8 Elite」的效能配置，對於注重性能的用戶而言無疑是一大吸引力。

至於LLM方面，手機廠商通常會自行訓練大模型，並搭配如ChatGPT的通用大模型。以蘋果為例，iOS 18不僅本地內建了一個低延遲、擁有30億參數的LLM，還接入蘋果私有雲計算的雲端大模型和ChatGPT，使用戶能以GPT接管siri，提升智慧體驗。三星則利用Google的Gemini AI引擎，結合自家 Bixby 語音助理，展現跨平台整合能力。
華碩新機除了搭載ChatGPT、Meta Llama 3 8B外，還導入自家開發的「福爾摩沙AI大模型」，在繁體中文辨識度上大幅優於對手，號稱市面上最懂繁體中文語意、台灣文化的AI。
與去年市售AI手機所謂的「AI」應用，例如修圖、畫圖、問答、執行簡單的操作（如定鬧鐘、行程等）等，今年品牌大廠則尋求讓AI更落地化、更先進的解決方案。
比如三星S25旗艦系列，「3C達人廖阿輝」發現，多數AI選項方面「可以完全設定成本地運行」，比如較有隱私疑慮的通話翻譯、通話文字轉錄、錄音會議筆記等；不過S Pen拿掉藍牙功能，「是非常可惜的一個點」，他感歎，這對於習慣遠端拍照或控制音樂播放等的用戶來說是一大遺憾。
YouTuber「3cTim哥」實測三星S25內建Galaxy AI跨應用執行鏈，一句「幫我查一下附近的海鮮料理餐廳，記錄我的新竹手機收購samsung Note」，即可自動從日程表讀取地址，並傳遞至地圖應用，省卻繁瑣的複製黏貼步驟，也就是以一個指令控制多個程式，成了新亮點。
華碩Zenfone 12 Ultra支援六大AI功能，強調能夠在雲端與地端自由切換，其中有五種功能可在手機（地端）執行，四款則以雲端運算，僅「AI即時通話口譯2.0」跟「AI圖片搜尋助手」則100%吃手機NPU，而「畫圖搜尋」功能則必須調用雲端資源搜尋。
儘管產品技術、功能推陳出新，YouTuber「彼得森」提醒消費者，選購時要注意「系統使用期限」，他在華碩Zenfone 12 Ultra評測中點到，該機系統更新期限僅有2年，三星和Google則提供7年，蘋果5至6年，相比之下，使用期限成了明顯劣勢。
▲華碩全球副總裁林宗樑透露，Zenfone 12 Ultra導入自家開發的福爾摩沙AI大模型。
華碩在6日發表會上就公告，「所有AI功能免費到2025年底」，未來的變化則另行公告；三星早在去年初就預告，Galaxy AI功能將在2025年底前，免費向支援該功能的裝置提供服務。台灣旗艦機雙雄的動作，是否為AI有價模式埋下伏筆，後續值得觀察。
究竟如何選出性價比高的AI手機？光華商場一位通路商告訴記者，選機時不僅要關注產品參數和價格，更要從實際應用場景出發，考慮哪些功能能真正解決日常需求，例如，商務洽談的用戶需要即時翻譯、語音轉文字等功能，愛攝影的用戶，應重視鏡頭性能與影像處理技術，此外，電池續航、充電速度、是否支持eSIM等都會是標配。
