Samsung has not announced the samsung galaxy s27 specs. There is no Unpacked invite, no official spec sheet and no confirmed price. Yet the leak trail is already unusually long: certification filings, a regulatory database listing, dummy units, and reports out of Korea about chip production.
The problem is that much of this coverage mixes solid evidence with guesswork. This guide separates them. Every important claim below is tagged as Certification-backed, Credible leak, Speculation, Unverified or Contradictory, so you can see how much weight it deserves.
The short version
- Lineup: four models are expected: Galaxy S27, S27+, a new S27 Pro, and S27 Ultra. The model names appear in the GSMA device database, which shows they exist internally but is not an announcement. (Certification-backed)
- Launch: early 2027. One tipster with a good Samsung record, Lanzuk, points to early January; other reports say January or February. (Credible leak)
- Biggest Ultra change: a larger battery, around 5,700 mAh typical, up from 5,000 mAh. (Certification-backed)
- Charging: 60W wired for the Ultra and Pro, per China's 3C database. That matches the S26 Ultra. (Certification-backed)
- Chip: the Ultra is most likely Snapdragon 8 Elite Extreme Gen 6, but Samsung is reportedly still deciding whether any Ultra gets Exynos 2700. (Credible leak, partly contradictory)
What Samsung has actually confirmed
Nothing about the S27 is official. What is official is the baseline it will be measured against. When Samsung announced the Galaxy S26 series in February 2026, the S26 Ultra introduced what Samsung called the first built-in Privacy Display on a phone. It kept the 5,000 mAh battery that Ultra models have carried since the S20 Ultra, but moved to 60W wired charging and 25W wireless. It runs the Snapdragon 8 Elite Gen 5 for Galaxy.
The S26 and S26+ carry 4,300 mAh and 4,900 mAh batteries, with 25W and 45W charging respectively. Those are the numbers the S27 models need to beat.
Battery: the one upgrade with real evidence
Samsung's Ultra has been stuck at 5,000 mAh for years, so a change here matters.
- A TÜV certification listing reportedly gives the S27 Ultra a typical capacity of 5,700 mAh, with a rated capacity of 5,534 mAh. The battery code reported by Galaxy Club is EB-BS958DBY. (Certification-backed)
- The S27 Pro is listed at roughly 5,200 mAh typical (about 5,087 mAh rated). Outlets quote slightly different figures here, from about 5,200 to 5,240 mAh, so treat the exact number as approximate. (Certification-backed, minor discrepancy)
Typical vs rated capacity. Manufacturers advertise typical capacity. Certification bodies often list the lower rated figure. 5,534 mAh rated and 5,700 mAh typical describe the same cell, not two different batteries.
A claim that doesn't hold up. An earlier tipster claimed the Ultra would exceed 6,000 mAh. Certification data points lower, to about 5,700 mAh. Where a filing and a single tipster disagree, the filing is the better evidence. (Contradictory, filing favoured)
What it means in practice. A 700 mAh increase is about 14%. Real battery life also depends on the chip and the display. The S26 Ultra's efficiency gains already produced longer web-browsing times in some reviews despite an unchanged cell, so a bigger battery plus a more efficient chip could add up to a visible improvement. That is a reasonable expectation, not a measured result.
Charging
China's 3C database lists the following wired speeds. (Certification-backed)
Model | Wired charging (3C / UL listing) | S26 equivalent |
|---|---|---|
Galaxy S27 | 25W | 25W |
Galaxy S27+ | 45W | 45W |
Galaxy S27 Pro | 60W | n/a (new model) |
Galaxy S27 Ultra | 60W | 60W |
In short, charging speeds are not changing. One tipster has also suggested Qi2 wireless charging for the Ultra, a feature that was rumoured for the S26 Ultra and did not arrive. That has only a single source so far. (Unverified)
Processor: the messiest part of the story
This is where reports contradict each other most, so it deserves care.
- Exynos 2700 is real and in production. Korean outlet The Elec reported mass production of Samsung's 2nm Exynos 2700 for the S27, S27+ and S27 Pro in markets such as Korea and Europe, with volumes reportedly about 10% above the previous Exynos generation. (Credible leak)
- The Ultra is likely Snapdragon. Multiple reports point to the Snapdragon 8 Elite Extreme Gen 6, but The Elec says Samsung has not finalised whether the Ultra also gets Exynos. Leaker kro said in early October that the Ultra may use Snapdragon in every market. (Credible leak)
- The Pro is disputed. Through the summer, Digital Chat Station and kro said the Pro would use Qualcomm globally. The Elec's later October report puts the European Pro on Exynos 2700. When credible sources disagree and the newer one is more specific, the newer report deserves more weight, but nothing is settled. (Contradictory)
- Some outlets are repeating one leak. Many articles restate the same few tipster claims. Repetition across sites is not independent confirmation.
For buyers in India, the practical point is that chip allocation by region is still unknown. Samsung's S26 series used Snapdragon in the Ultra, and nothing official says the S27 Ultra will differ.
Memory and storage
A leaker reported that the S27 Ultra and Pro will use LPDDR6 RAM and UFS 5.1 storage, a step up from the LPDDR5X and UFS 4.0 in the S26 Ultra. Reported configurations run from 12 GB RAM with 256 GB storage up to 16 GB RAM with 1 TB for the Ultra. (Credible leak, single source)
There is a cost warning attached. Memory prices have risen through 2026, and commentary notes that any price figure is provisional.
Display and design
- Size and shape. Dummy units and CAD renders suggest dimensions almost identical to the S26 Ultra (reported at about 163.76 x 78.25 x 7.97 mm, against 163.6 x 78.1 x 7.9 mm on the S26 Ultra). Expect a familiar body. (Credible leak)
- Panel. One tipster claims an upgrade from the M14 OLED panel to an M16 generation, with higher brightness to offset dimming from the Privacy Display, and DC dimming for comfort at low brightness. (Credible leak, limited corroboration)
- Variable aperture. Reportedly dropped from Samsung's plans. (Credible leak)
- Liquid cooling. A Korean report said Samsung is considering a liquid cooling system for the S27 series. "Considering" is not a decision. (Speculation)
Cameras: what's reported, and what isn't
Camera rumours are the hardest to pin down.
- Telephoto change. Some reports say the S27 Ultra drops the 3x telephoto, leaving a main camera, an ultrawide and one 50 MP telephoto. At least one outlet notes that no second source has confirmed this. (Credible leak, uncorroborated)
- Zoom sensor. A tipster says the 5x periscope keeps the S26 Ultra's 1/2.52-inch sensor, so a new zoom sensor looks unlikely. (Credible leak)
- A 250 MP main camera. This appears in some low-quality aggregator articles, with no supporting source. Don't plan around it. (Unverified)
Why megapixels matter less than you'd think. A 200 MP sensor mostly bins pixels into much larger effective ones. Sensor size, lens aperture and image processing do more for night photos and zoom quality than the headline resolution. If the S27 Ultra keeps its main sensor, expect differences to come from processing rather than a bigger number.
The new Galaxy S27 Pro
The Pro is the most interesting addition. Leaks describe a smaller, roughly 6.47-inch phone with near-Ultra cameras, a battery of about 5,200 mAh and Privacy Display, but no S Pen. Its price is rumoured to land between the base model and the Ultra. (Credible leak, details unconfirmed)
If accurate, it would split today's Ultra buyers into two groups: people who want the camera and screen quality, and people who want the S Pen and the largest body.
S27 vs S26 comparison

|---|---|---|
Battery | 4,300 mAh | Not reported |
Wired charging | 25W | 25W (certification) |
Chip | Regional split | Exynos 2700 expected in most markets |
Galaxy S26+ (official) | Galaxy S27+ (reported) | |
|---|---|---|
Battery | 4,900 mAh | Not reported |
Wired charging | 45W | 45W (certification) |
Chip | Regional split | Exynos 2700 expected in most markets |

|---|---|---|
Battery | 5,000 mAh | About 5,700 mAh typical (certification) |
Wired charging | 60W | 60W (certification) |
Chip | Snapdragon 8 Elite Gen 5 for Galaxy | Snapdragon 8 Elite Extreme Gen 6 likely |
Memory | LPDDR5X, UFS 4.0 | LPDDR6, UFS 5.1 (single-source leak) |
Panel | M14 | M16 (limited corroboration) |
Telephoto | 3x and 5x | Possibly one telephoto only |
Price and release date
Samsung has said nothing on either. Reported US prices for the Ultra sit between $1,399 and $1,499, with the Pro lower. These come from leaks and are shaky, because memory costs could shift them. For India, there is no reliable pricing information at all. (Unverified)
On timing, Lanzuk says early January 2027. Other reports say January or February. One summary notes that the launch window has already moved once. Treat any specific date as a projection until Samsung sends an invite.
Software
The S27 series is reported to be associated with One UI 9.5, which Samsung is said to be developing. Samsung's update policy for the S27 has not been announced, and the S26 policy should not be assumed to carry over. (Speculation)
Should you wait for the S27?
That depends on what you own.
- S26 Ultra owner: the reported changes (battery, memory, possibly the panel) look incremental. The main reason to upgrade would be the battery, and that is not yet confirmed by Samsung.
- S24 Ultra or older: waiting makes sense if you can, because the S27 Ultra looks like the first meaningful battery change in years.
- Buying now: the S26 Ultra is a proven product, and its price may fall once the S27 is announced.
