Galaxy S27 Ultra Rumors: Bigger Battery, New Camera Layout and What to Expect
SpexHive Editorial

news
Three Ultras in a row, and the battery has never moved. The Galaxy S24 Ultra, the Galaxy S25 Ultra and the Samsung Galaxy S26 Ultra all carry exactly 5,000 mAh. Now the first serious rumors about the Galaxy S27 Ultra say Samsung is finally ready to break that streak, and that is only one of the changes people are talking about.
Samsung has not announced anything, so every figure below comes from leaks and rumors from our sources, or is an educated guess. We went through the latest rumors, checked them against what the current Ultra really offers in the SpexHive database, and sorted them by how believable they sound. Read to the end for the section that matters most: which rumors we would trust, and which we would not.
Current model figures come from the SpexHive database. The S27 Ultra column is rumor only.
The battery: finally more than 5,000 mAh?
This is the rumor with the most weight behind it. Several leaks now point to a battery of about 5,700 mAh, up from 5,000 mAh in the current Ultra. That would be roughly 14% more capacity, and the first increase after three generations at 5,000 mAh. A separate certification listing, according to our sources, shows a rated capacity of 5,534 mAh. Rated and typical figures are not the same thing, so the two numbers could fit together: 5,534 mAh as the guaranteed minimum, and 5,700 mAh as the figure Samsung would put on the box.
The charging story is more interesting than the capacity. According to our sources, Samsung is keeping the 60 W limit but changing how it gets there: pushing harder in the early part of the charge so the battery fills faster overall, while keeping heat lower. For comparison, the Samsung Galaxy S26 Ultra already charges at 60 W by wire and 25 W wirelessly, so nothing changes in the headline numbers.
Is it enough? The Xiaomi 18 Pro Max in our database carries 8,500 mAh in an 8.4 mm body, and some Chinese phones are reportedly shipping with batteries above 10,000 mAh. A 5,700 mAh Ultra would still be conservative next to them. Silicon carbon technology is the reason, and you can read how it works in phones that already ship with it.
Cameras: 200 MP stays, the telephoto is the question
The main camera is the safest part of the leak. Leaks expect a 200 MP Samsung ISOCELL HP6 sensor again, which fits the roughly 200 MP main camera on the S24 Ultra, S25 Ultra and S26 Ultra. Most of the talk is about image processing instead: better results in low light and in high contrast scenes, with more AI assistance. Samsung does not usually publish processing details before launch, so treat any claim about specific gains with care.
The telephoto is where our sources disagree:
According to leaks, Samsung wants a 50 MP 5x telephoto (reportedly with an f/2.9 aperture) and would drop the separate 3x lens, leaving a three camera system on the back.
Another leak, from a well known Samsung leaker, says Samsung is not changing the telephoto camera at all.
The current Samsung Galaxy S26 Ultra has four rear cameras: the 201.3 MP main, a 50.3 MP ultra wide, a 10 MP telephoto and a 49.9 MP periscope with 5x optical zoom. Losing the 10 MP telephoto would simplify things but would leave a gap between the main camera and 5x, which would have to be filled by cropping into the 200 MP sensor. That works well on a sensor this large, but it is a real change for people who shoot portraits at about 3x.
Chip and cooling: 2 nm arrives
Samsung is expected to move to a 2 nm chip for the S27 series. The current Ultra uses the Snapdragon 8 Elite Gen 5 for Galaxy, built on 3 nm. For the S27 the rumors expect the Exynos 2700 in some markets and a next generation Snapdragon in others, as Samsung has done in some earlier generations.
One leak says early benchmarks, which our source does not name, put the Exynos about 10% ahead in multi core performance of its Snapdragon counterpart. That is a claim to hold at arm’s length. Unnamed benchmarks on pre release hardware are the least reliable kind of evidence.
The cooling story is easier to believe, because it is practical engineering:
A larger vapor chamber, to keep the phone cooler under load.
A layout in which, according to leaks, Qualcomm positions the memory modules around the chip to help spread heat.
Earlier software tuning by Samsung, so the phone feels finished on day one.
Design: a new look on the back
From the front, the S27 Ultra is expected to look very familiar. The change is on the back, where leaks describe a horizontal, rectangular camera module in place of the vertical column of individual rings that has defined recent Ultras. Another leak mentions a flat, redesigned back with built in magnets for charging accessories.
The details conflict. One source says the phone will be slightly heavier because of the larger battery, while another headline talks about a slimmer build. Both cannot be right. The current Samsung Galaxy S26 Ultra is already thin at 7.9 mm and weighs 214 g, so a bigger battery inside the same shell would almost certainly add a few grams.
The rumored colours are black, blue, light pink and white, with a violet version sold only through Samsung’s own store. This has not been confirmed.
Memory and storage
The two upgrades with the most day to day impact are probably the least discussed. Our sources expect LPDDR6 RAM and UFS 5.1 storage, both a step faster than the previous generation. Up to 16 GB of RAM is mentioned, matching what the Samsung Galaxy S26 Ultra already offers. Faster storage means quicker app launches, faster 8K video saving and quicker large file copies, all things you notice every day.
Price and release date
Price. The leaks say the base model will cost roughly $74 to $96 more than its predecessor, and that the 1 TB version will pass $2,000. Memory prices have been rising across the industry, and several phone makers have already raised prices this autumn, so an increase is plausible. Taxes and local pricing will make the final figure different in every country.
Release date. Our sources vary. One points to a window of about 10 to 15 January 2027, another to January or February 2027. Samsung’s own history, from the dates in our database, supports that range:
Galaxy S24 Ultra: announced 17 January 2024;
Galaxy S25 Ultra: announced 22 January 2025;
Galaxy S26 Ultra: announced 24 February 2026, and released on 6 March.
A few rumors even give 2026 launch dates for the S27, which cannot be right with the year nearly over. Our sources also mention a fourth model, a possible Galaxy S27 Pro, joining the lineup.
How much should you believe?
Almost all of this comes from leaks and rumors passed along by our sources, with a few mentions of certification listings and well known leakers. That is very different from a supply chain report or official documents. Here is our honest ranking:
How believable
Rumors
Likely
A bigger battery (several leaks agree and a certification listing fits), a 200 MP main camera, a 2 nm chip, a January or February 2027 launch, a price increase.
Possible
The new horizontal camera module, LPDDR6 and UFS 5.1, a larger vapor chamber, a violet online only colour.
Doubtful
The dropped 3x telephoto (directly disputed), the 10% Exynos benchmark lead, any claim about a slimmer body.
Our confidence in each rumor. This is a judgement, not a measurement.
Should you wait for the S27 Ultra?
Own a Galaxy S26 Ultra? Stay put. A bigger battery and a new chip are nice, but a one year old Ultra will not feel old. See what really changed last year in our Galaxy S26 Ultra vs Galaxy S25 Ultra comparison.
Own an S24 Ultra or older? Waiting until early 2027 makes sense if you are not in a hurry. If you cannot wait, the current model is excellent.
When will the Galaxy S27 Ultra launch? Nothing is official. Our sources point to January or February 2027.
How big will the battery be? Rumors say about 5,700 mAh, against 5,000 mAh in the Galaxy S26 Ultra.
Will it charge faster? The 60 W limit is rumored to stay, with a reworked charging curve to cut the time.
Will it have a new camera design? Leaks mention a horizontal rectangular module, but this is unconfirmed.
How much will it cost? Leaks suggest a rise of about $74 to $96 on the base model, and a 1 TB version above $2,000.
What we think
If even half of these rumors are right, the Galaxy S27 Ultra will be the biggest change to the Ultra in years: a battery that finally grows, a new chip generation, faster memory and a redesigned back. If the price rises as well, the question will be whether Samsung has done enough to justify it. We will keep this story updated as soon as Samsung says anything official, so check back.
