Samsung Galaxy S25 review: a genuinely good small phone that is hard to justify at full price

Somewhere in the last few years the small phone quietly became a niche product. Screens grew, batteries grew with them, and anyone who wanted a phone they could reach across with one thumb was told to buy last year’s model or accept a compromise. The Samsung Galaxy S25 is Samsung’s answer to that: a 6.2-inch display in a body that still fits a hand, with the same flagship chip as its larger siblings.

That is the case for the S25, and it is a good one. The case against it is narrower but sharper, and it is entirely about money: the specification is appealing, and the full price is hard to defend, because the improvements over the previous generation are modest. Whether it is right for you depends less on what it does than on when you buy it.

This review is based on Samsung’s published specifications, the manufacturer’s documentation, and the consistent themes in owner reports. We have not handled a Galaxy S25, and we have not run our own battery or camera tests.

What the Galaxy S25 is actually for

Read the feature list and the intent is clear: a 6.2-inch display, the Snapdragon 8 Elite, seven years of OS updates, and wireless charging. That is a specification for someone who wants a flagship experience in a compact body, and who intends to keep the phone for a long time.

The size is the defining decision. A 6.2-inch screen is small by the standards of 2026 flagships, and that is the point: it is the size that lets you reach the far corner with the hand already holding the phone, whether you are carrying a coffee, holding a child’s hand, or standing on a bus with one arm on a rail. Anyone who has owned a large phone knows how often that matters.

Seven years of OS updates is the second defining feature, and it changes what you are buying. A phone with seven years of support is not a two-year purchase with a three-year tail; it is a device you can plan to keep until the battery gives out. That reframes the price: a phone that lasts twice as long can cost more up front and still be cheaper per year.

The Snapdragon 8 Elite and wireless charging round out a package designed to feel current rather than experimental. This is not a phone chasing a novel form factor; it is a phone trying to be the best small Android device available.

What the published specifications tell you

Four specification points are worth reasoning about.

The first is the 6.2-inch display. The important consequence of a smaller screen is not resolution but ergonomics: a phone you can operate one-handed is more comfortable in the situations where phones are actually used.

The second is the Snapdragon 8 Elite. A flagship chip in a compact body means the S25 does not ask you to trade performance for size, which was the traditional compact-phone compromise, so it should stay responsive for years rather than feeling slow after the second one.

The third is seven years of OS updates, which Samsung describes as the longest commitment available on Android. That claim is worth taking seriously, because software support is what determines how long a phone stays usable and safe, and it is the specification most likely to be undervalued at purchase.

The fourth is wireless charging, which is convenience rather than capability. Paired with Samsung’s claim that the S25 charges quickly enough for a useful top-up before you go out, it makes the smaller battery less of a daily problem than the capacity alone suggests.

Living with it: the scenarios that matter

The one-handed commute

This is the scenario the S25 was built for. Standing on a train with one hand on a rail, you can reach the top of a 6.2-inch screen without shifting your grip. Owners consistently describe this as the reason they chose a compact phone and would choose one again.

The long-term purchase

If you keep phones for four or five years, the S25’s case gets stronger. Seven years of updates means the software will not be the reason you replace it, which leaves the battery as the main long-term wear item. For someone who dislikes changing phones, long support plus a body that will still feel modern is a more honest value than a cheaper phone that stops receiving updates in year three.

Battery anxiety on a heavy day

This is where the S25 gives ground. Its battery capacity is smaller than the Plus and Ultra models, the inevitable consequence of a compact body. Samsung’s claim that it charges quickly enough for a top-up before going out softens the problem for anyone near a socket. But if your day involves heavy use away from power — long travel, navigation, lots of photos — you will notice the smaller capacity by evening.

Photography in ordinary life

The S25 is a competent everyday camera. If your priority is photographing fast-moving children or pets, camera processing matters more than hardware, and Google’s Pixel line is the more specialised tool.

Where it falls short

Two downsides are on the record, and both are real.

The first is price. At full list, the S25 is hard to justify against last year’s model, because the changes between generations are iterative rather than dramatic. You are paying flagship money for a modest step forward, and in a category where the previous generation is still fast and now cheaper, that is a genuine cost of buying new. The phone becomes easy to recommend the moment it discounts — which, historically, it does.

The second is battery capacity. It is smaller than the Plus and Ultra, so heavy users will feel the difference by the end of a demanding day. Fast charging helps, and it does not remove the constraint; it means the constraint can be managed if you have a socket.

Who should buy it, and who should not

Buy it if you want a compact Android phone without giving up flagship performance. Buy it if you keep phones for years and want the longest software support Android offers, because seven years of updates is what makes the price defensible over time. Buy it if one-handed use matters to your daily life.

Skip it if you are buying at full list and you are not in a hurry; the improvements over the previous generation are modest, and the sensible play is to wait for a discount. Skip it if you need maximum battery life away from power, because the capacity is smaller than the Plus and Ultra. Skip it if photography of moving subjects is your priority, because that is the Pixel’s strength rather than Samsung’s. And skip it if you want the biggest screen or the most camera hardware in the range.

How it compares to the alternatives

	Samsung Galaxy S25	Apple iPhone 16	Google Pixel 9
Display	6.2-inch	6.1-inch	6.3-inch
Chip	Snapdragon 8 Elite	Apple silicon	Tensor G4
Update commitment	Seven years of OS updates	Long support as part of Apple’s ecosystem	Seven years of updates
Best for	One-handed use, Android users leaving a large phone, long support	iPhone upgraders, families on shared Apple services, reliable point-and-shoot photos	Photos of children and pets, clean Android, discount hunters
Standout strength	Compact without the usual battery penalty, and the longest update commitment on Android	Consistent photos without fiddling, USB-C, and strong resale value	The most reliable point-and-shoot photos of moving subjects, with clean Android
Main tradeoff	Smaller battery than the Plus and Ultra; full price hard to justify against last year	Display refresh rate behind Android rivals at this price; slow charging by 2026 standards	Runs warmer under sustained gaming; average rather than class-leading battery

Read that as a set of priorities rather than a ranking. The S25 is the compact long-term Android phone, the iPhone 16 is the safest choice inside Apple’s world, and the Pixel 9 is the pick for photographing children and pets. All three sit in the same broad tier, so check the current price on each.

Frequently asked questions

Is the Galaxy S25 battery big enough?

The capacity is smaller than the Plus and Ultra, so a heavy user will notice the difference by evening. Samsung’s claim is that it charges quickly enough for a useful top-up before going out, which softens the issue for anyone near a socket. For a full day of heavy use away from power, the larger models are the safer choice.

Why is the S25 hard to justify at full price?

Because the improvements over last year’s model are iterative rather than transformative, so paying list price buys a modest step for a flagship sum. The phone becomes an easy recommendation the moment it discounts, which historically it does.

Does seven years of updates really matter?

It matters if you keep a phone for a long time: seven years of OS updates is the longest commitment on Android, so the phone you buy today stays current long after most rivals stop receiving updates.

Should I buy the S25 or the Pixel 9?

Choose the S25 if one-handed size and long update support matter most. Choose the Pixel 9 if camera processing for moving subjects — children and pets — is your priority, and if you prefer clean Android. Both run for seven years of updates, so the decision comes down to size and camera.

What we could not verify

We have not handled a Galaxy S25. That means we cannot confirm how the 6.2-inch body feels in a hand, how the display behaves in direct sunlight, or whether its balance makes one-handed use as comfortable as the specification implies. Those are the questions a hands-on review would settle, and the ones we are explicitly not answering.

We have not measured battery life, charging speed or camera performance, so every performance claim here comes from Samsung’s published specification or from the pattern of owner reports. We have not verified how the Snapdragon 8 Elite behaves under sustained load in this specific body, where thermal design matters more than in a larger phone. We have not tested the camera’s processing of fast-moving subjects, and we cannot tell you how its output compares with the Pixel 9 in practice. Finally, we have not checked the current selling price at any retailer, so treat every cost reference here as a tier rather than a number.
