Galaxy S26 Ultra: The Best Android Phone Has One Painful Catch for S25 Owners, With a Free Fix

The Galaxy S26 Ultra ran for 30 hours and 3 minutes in Engadget’s video battery test. That is about 30 minutes longer than last year’s model, and it comes from the very same 5,000mAh battery.

That one detail sums up the whole phone. Samsung changed a lot of small things, and almost none of them is dramatic. So the real question is not whether this is a great phone. It is whether it is a great phone for you.

Our answer depends on what you hold now. We have not used this phone ourselves, so the verdict below rests on published specs and lab tests from the reviewers we link. Where they disagree, we say so.

The Short Version

• It is the most complete Android phone right now. Engadget scored it 90 out of 100, and Digital Trends gave it an Editors’ Choice badge.
• The upgrade is small. GSMArena calls it an “unexciting upgrade” over last year, though still a well-balanced phone.
• Battery life and charging are the real gains. With the same cell size, it still lasts longer and charges at 60W.
• Cameras improve in the dark, not elsewhere. The sensors are unchanged, but the wider main lens helps at night.
• Our call: buy it if you are on a phone from 2023 or older, wait if you own an S25 Ultra, and skip the 1TB version.

What Actually Changed on the Galaxy S26 Ultra

First, the shape. The phone is 7.9mm thick and weighs 214g, according to GSMArena’s spec sheet. Reviewers describe it as thinner and lighter than before.

Next, the chip. It uses the Snapdragon 8 Elite Gen 5, with 12GB of RAM on the two smaller versions and 16GB on the 1TB model. In other words, there is no shortage of speed.

Then, the software. Samsung promises up to seven major Android updates. That means a phone bought today should stay supported for years.

Finally, the screen. It is a 6.9-inch panel with a 2,600 nit peak, the same as last year. The new part is Privacy Display, which narrows the viewing angle so people beside you cannot read your screen.

This table shows what the main reviewers measured or confirmed, not what Samsung’s brochure says.

Battery and Charging: The Best Part

Battery life is where this phone earns its score. In Engadget’s test it beat its predecessor by roughly 30 minutes, and only the OnePlus 15 and OnePlus 15R lasted longer among the phones it compared.

Real use looks different from a video loop. Digital Trends reports five to six hours of screen time on heavy days with 5G, gaming and GPS. On moderate days it reached closer to eight hours.

Charging is the other win. Wired charging rose from 45W to 60W, and the review measured a full charge in about 54 minutes. So you spend noticeably less time at the wall.

There is one complaint. GSMArena says the battery density and capacity are still behind the curve. Other makers fit bigger cells into phones of this size.

Camera: Better at Night, Unchanged Elsewhere

The sensors are the same as on the S25 Ultra, according to Engadget. What changed is the glass in front of them.

The 200MP main lens opened up from f/1.7 to f/1.4. As a result, night shots are noticeably better. Engadget’s reviewer found it roughly matched the Pixel 10 Pro in a dim room, with less noise.

The 5x telephoto also improved, from f/3.4 to f/2.9. However, Digital Trends says that lens tends to hunt for focus. It also reports a low-light shutter lag of half a second to a second and a half, and calls 100x zoom mushy.

GSMArena is blunter. It says the camera hardware trails the top Android camera phones. So if photography is your only priority, this is not an automatic win.

Privacy Display is the headline feature, and it works better than most gimmicks. Engadget found that standard mode has very little effect on image quality, so you can leave it on.

Maximum protection is different. It causes a noticeable drop in contrast and brightness, and the reviewer felt it was not worth it.

The smart option is automatic mode. It switches on for notifications or chosen apps, such as banking. That gives you privacy where it counts without dimming everything else.

The catch is elsewhere.

Privacy Display and the Painful Catch

Every reviewer found something to complain about, and the complaints are consistent. First, GSMArena says the CPU throttles heavily under longer loads. Digital Trends also mentions heat and throttling.

That matters if you play demanding games for an hour. For everyday use you are unlikely to notice.

Second, the water rating is only IP68. GSMArena points out that some other Android phones now offer IP69, and iPhones can go deeper.

Third, there is no built-in magnetic ring for Qi2 accessories. Engadget lists this as a con. You need a case if you want magnetic chargers and mounts.

Finally, the screen lacks some features that rivals have, including Dolby Vision, according to GSMArena. None of these is a dealbreaker, but together they explain why the review calls the upgrade modest.

Who Should Buy, Wait or Skip

Buy it if you own a phone from 2023 or older. You get a faster chip, a modern screen, longer battery life and faster charging, plus seven years of updates. For you, the jump is large.

Buy it if you want the S Pen. GSMArena notes that it is still unique among flagships. No other phone in this class offers one.

Wait if you own an S25 Ultra.

The sensors are the same, the screen specs match and the battery is the same size. You would pay for a 30-minute battery gain and faster charging.

Our S27 Ultra wait-or-buy guide explains what the next model is tipped to change, and the S27 release date report covers timing.

Wait if you own an S24 Ultra, unless the battery bothers you. We covered this in our S24 Ultra long-term verdict. The older phone still runs well.

Skip the 1TB version. It costs far more, and most people never fill 512GB. Buy the middle tier at most.

Skip it if you play demanding games for hours. The throttling reports suggest a gaming phone will serve you better.

Galaxy S26 Ultra Price and Where to Buy in India

This section is only for readers in India. Everyone else can skip to the next heading.

At launch, the 12GB and 256GB version cost Rs 1,39,999, the 512GB version Rs 1,59,999 and the 1TB version Rs 1,89,999. Sammobile reported a Flipkart price of Rs 1,24,999 in August, and an effective price of Rs 1,11,699 after offers.

On 3 November, Beebom’s price tracker showed the 256GB version at Rs 1,29,890 on Flipkart and Rs 1,39,999 on Amazon. It also listed a Rs 4,000 cashback with Axis Bank or SBI credit cards, which brings Flipkart to Rs 1,25,890.

Be careful with the headline numbers. My Mobile India reported a Samsung festive effective price of Rs 79,999 on 26 October. However, that assumes a Rs 15,000 discount and the maximum Rs 60,000 exchange value, so few buyers will get it. The same article lists Samsung’s own price as Rs 1,54,999.

We could not confirm the Samsung store price ourselves, and trackers disagree on it. Check the live listing before you pay. We checked these prices on 3 November 2026.

Also, the One UI 9 update based on Android 17 is rolling out, according to Beebom. Our One UI 9 release date guide lists the order by model.

Quick Answers

Is the Galaxy S26 Ultra worth buying?

Yes, if you are upgrading from a phone that is two or more generations old. For S25 Ultra owners, the gains are too small.

How long does the battery last?

Engadget measured 30 hours 3 minutes of video. Digital Trends saw five to six hours of screen time under heavy use.

Does it have a bigger battery than last year?

No. The capacity is still 5,000mAh, but it lasts longer and charges at 60W.

How does it compare with the iPhone?

We cover that in our iPhone 18 Pro Max vs Galaxy S26 Ultra comparison. The short version is that the two are close and suit different people.

The Bottom Line

The Galaxy S26 Ultra is the most complete Android phone you can buy, and it earned that from reviewers who did not agree on much else. Battery life, charging, the S Pen and seven years of updates make it easy to recommend.

The catch is that it is a modest step forward. Buy it if you are coming from an older phone. Wait if you already own the S25 Ultra. That is the free fix: keep your phone, spend nothing, and let the next model come to you.

What we cannot know yet is how the S27 Ultra will compare. Leaks suggest a bigger battery, but nothing is confirmed, so treat that as a rumour for now.
