<p>The iPhone 18 Pro is the better phone for people who film video, use their phone one-handed and live inside Apple's ecosystem. The Galaxy S26 Ultra is the better phone for people who want a big screen, long zoom and a display nobody can read over their shoulder. Price alone does not separate them as cleanly as it first appears.</p>
<h2>Two flagships, two sizes</h2>
<p>Apple's iPhone 18 Pro starts at $1,199 for 256GB in the US, according to Apple's store. Samsung lists the Galaxy S26 Ultra from $1,299.99 on its US site, and PhoneArena lists $1,300 for 12GB and 256GB, $1,500 for 512GB and $1,800 for the 1TB model. Samsung announced the Ultra on February 25, 2026, so it is the older phone by about seven months. Apple's phone arrived with iOS 27 in September.</p>
<p>The size gap matters more than the $100 headline difference. The iPhone 18 Pro has a 6.3-inch screen, while the S26 Ultra has a 6.9-inch panel. Apple's closer match in size is the iPhone 18 Pro Max, which has a 6.9-inch display and starts at $1,299. We compare the smaller Pro here because it is the phone most buyers cross-shop, and because the Pro Max differs mainly in screen size and battery.</p>

<p>Apple's figures come from its tech specs and store pages, and Apple notes its tests used preproduction units. Samsung's camera, battery, weight, storage and price figures come from its US product page. The Galaxy's resolution, refresh rate and water resistance rating come from PhoneArena, because Samsung's own specs page could not be read.</p>
<h2>Design and display</h2>
<p>Both phones use an aluminium frame with durable front glass: Ceramic Shield 2 on the iPhone, and Gorilla Glass on the Galaxy. The weights are nearly identical at 211g and 214g, which is the surprise. Samsung has spread almost the same mass across a much larger body, so the Ultra feels thinner and lighter than its size suggests, while the iPhone feels dense and compact.</p>
<p>The Galaxy's headline display feature is the built-in Privacy Display, which Samsung calls the first on a mobile device. It can hide the entire screen, specific apps, notifications or PIN entry from viewers at an angle. Nothing on the iPhone matches it. Apple answers with brightness: its outdoor peak of 3,000 nits beats Samsung's 2,600 nits, though both are far brighter than most people will ever need.</p>
<h2>Performance</h2>
<p>The A20 Pro has two high-performance cores and four efficiency cores, plus a seven-core GPU with neural accelerators. Samsung's Snapdragon 8 Elite Gen 5 for Galaxy is, by Samsung's own claim, 19 percent faster on CPU than the S25 Ultra. Neither company publishes a head-to-head figure, and we have not benchmarked either phone, so treat both as fast enough for anything you will throw at them. The Galaxy carries more memory, with 12GB or 16GB depending on storage. Apple does not publish RAM.</p>
<h2>Cameras</h2>
<p>This is where the two phones diverge. TechRadar's side-by-side test of the iPhone 18 Pro and Galaxy S26 Ultra found the iPhone's colours more natural and its shadows stronger, while the Galaxy was brighter, more contrasty and more saturated. Detail on the main sensor was roughly equal. In low light the iPhone took slightly brighter pictures, though the reviewer called it close.</p>
<p>Zoom favours Samsung. The Galaxy has a 5x telephoto against Apple's 4x, and TechRadar found it sharper at those distances. It also keeps usable results to roughly 50x, against a 40x digital limit on the iPhone. Reports differ on whether the Ultra also carries a separate 3x lens, since Samsung's spec block lists only the 200MP main, 50MP ultra wide and 50MP 5x telephoto. Apple's trick is cropping: its 48MP telephoto gives an optical-quality 8x at 200mm.</p>
<p>For video, iGeeksBlog prefers the iPhone, citing Dolby Vision recording, Smart Focus Tracking and Audio Mix. Apple supports 4K Dolby Vision at up to 120fps, ProRes, ProRes RAW and Apple Log 2. The Galaxy records 8K at 30fps and 4K at 120fps, according to PhoneArena. The iPhone's 18MP Center Stage front camera also beats Samsung's 12MP selfie sensor on paper, and TechRadar gave Apple the edge for selfies.</p>
<h2>Battery and charging</h2>
<p>On paper the iPhone wins the battery contest. Apple rates the 18 Pro at up to 36 hours of video playback, against 31 hours for the Galaxy, and the Pro Max stretches to 45 hours. These are manufacturer claims measured under different conditions, and no independent battery test of the 18 Pro against the S26 Ultra has been published in the reviews we read, so we will not call a winner on endurance.</p>
<p>Charging is closer. Apple claims 50 percent in about 15 minutes, but only with a 60W-capable adapter, and the box contains only a USB-C cable. Samsung claims 75 percent in around 30 minutes with its Super Fast Charging 3.0. Samsung does not state a wireless charging speed on the pages we could read. Outlets list figures of 15W and 25W, so check the configuration you buy. Apple lists 25W on both MagSafe and Qi2.</p>
<h2>Software and updates</h2>
<p>The iPhone 18 Pro runs iOS 27, and the Galaxy runs One UI 8.5 on Android 16. Samsung is reported to promise seven years of OS updates for the S26 series, according to PhoneArena and iGeeksBlog, though we could not find that figure on Samsung's own pages. Apple does not publish a support period. The practical difference is ecosystem: if you own a Mac, iPad or Apple Watch, the iPhone fits into them with no effort, while the Galaxy suits people who like customisation and use Windows or Android accessories.</p>
<h2>Which should you buy?</h2>
<p>Buy the iPhone 18 Pro if you want a phone that fits in one hand, shoot a lot of video, take selfies, or already use other Apple devices. It is also $100 cheaper at the entry tier. Buy the Galaxy S26 Ultra if you want a 6.9-inch screen, longer optical zoom, a Privacy Display for commutes and offices, or a long update promise. If screen size is the deciding factor, step up to the iPhone 18 Pro Max at $1,299, which matches the Galaxy's size and nearly matches its price.</p>
<p>Both phones are strong enough that you will not regret either choice. The deciding questions are size and zoom, not speed.</p>
