Samsung Galaxy S25: Compact, Fast, and Still Ahead in 2026

Samsung had a lot to prove after the Galaxy S24. Across Europe, the Exynos chip in most Galaxy S24 units drew complaints: thermal throttling crept in under sustained load, and battery life disappointed compared to the Snapdragon version available in the US. The S25 changed that. For the first time globally, Samsung shipped the Snapdragon 8 Elite, and the difference is measurable.

At 162g and 7.2mm thin, the S25 remains one of the few compact phones that pairs top-tier performance with a pocketable form factor, a combination that grows harder to find in 2026. With the Galaxy S26 now at launch pricing, the S25 has dropped considerably: available refurbished for a fraction of its launch price, with 6 Android updates still to come.

Why the Samsung Galaxy S25 still wins in 2026

Snapdragon 8 Elite: no thermal compromise. The S25 runs the Snapdragon 8 Elite without thermal panic. In extended benchmark sessions, the external surface stayed below 42°C, disciplined for a phone this thin. App switching, gaming, and 4K video run without hesitation, and 18 months of updates have refined the experience further.

One UI 7: the version Samsung’s software always promised. Multiple reviewers called it a turning point. Good Lock adds another layer: custom icon packs, tailored home screen grids, and advanced gesture animations, without the fluidity loss that third-party launchers introduce on Pixel or the forced Google bar that limits customisation elsewhere.

7 years of updates, actively honoured. The S25 launched with Android 15 and is running Android 16 in 2026, with 6 major updates still ahead. This is not a theoretical commitment.

What the Samsung Galaxy S25 genuinely excels at

Compact when compact matters. At 162g and 7.2mm, the Galaxy S25 fits in a front trouser pocket without a second thought. Multiple reviewers across 2025 and 2026 called this increasingly rare: a phone easy to use one-handed in a market moving toward wider, heavier slabs. If that matters to you, the S25 delivers.

Fingerprint sensor that works every time. The ultrasonic under-display fingerprint sensor reads fast from standby and stays consistent, even through a thick tempered glass screen protector. Multiple long-term reviewers flagged it as one of the best implementations on any phone available now.

Call AI that earns its place. The S25 records calls, transcribes them, summarises them, and translates in real time: voice to text to voice, within the same call. Users on long-term daily-driver reviews confirmed it as a practical tool, and the capability is ahead of what iOS offers natively.

One UI depth without the trade-off. Good Lock, Samsung’s free customisation layer, enables custom icon packs, grid size adjustments, and gesture animation tuning, all without installing a third-party launcher or losing the phone’s native fluidity. Pixel forces a Google bar on the home screen. iOS does not allow icon packs. On the S25, both constraints are gone.

Battery that lasts the day. The Snapdragon 8 Elite’s efficiency makes the 4,000 mAh battery go further than the number suggests. Normal use returns 3 to 5 hours of screen-on time. Under a sustained stress test, used as a 5G mobile hotspot for nearly 5 hours during a live video upload, the phone still made it to 19:00 before running out.

Galaxy S25: handy for everyday work, with a few catches

The compact S25 earns its keep in everyday work. In One UI’s Battery settings, cap the CPU at 70% of its maximum speed on quieter days of browsing, messaging or music to extend battery life. Long-press an image or screenshot and pin it to the edge of the screen: a number or recipe stays visible while you switch apps. Samsung’s built-in recorder transcribes meetings; paste the transcript into Gemini for a summary in under two minutes, without a third-party subscription. Good Lock from the Galaxy Store also lets you apply icon packs without changing launchers or losing fluidity.

That ease has a battery ceiling. In the countryside, a basement or a commute dead zone, weak signal makes the modem raise its transmit power. The resulting drain can exceed an hour of gaming. Wired charging is 25W when 35W or 45W is common at this price point: 30 minutes from empty gets you roughly 50%. If a quicker top-up matters more than compact size, the Galaxy S25+ offers 45W.

The cameras suit everyday shots better than demanding ones. Food mode, under More in the camera, automatically adjusts colour warmth, sharpness and depth for a meal. In good light, the main camera takes natural, accurate photos, with better colour processing than the Galaxy S24 and earlier models. But the hardware traces back to the S22 era: the ultrawide has no autofocus, so it cannot take macro shots; the 10MP telephoto suits social sharing better than large prints; and demanding low-light stills show digital noise. Choose the S25 Ultra if serious photography is the priority.

A case solves one problem, provided you choose the right one. ‘Qi2 Ready’ is not native Qi2. Unlike the Google Pixel 10, the S25 has no built-in magnets, so magnetic Qi2 accessories require a magnetic case. Samsung’s clear case costs around £30 but is poorly reviewed for its slippery, flimsy feel and lack of screen protection. The Spigen Ultra Hybrid S is the better pick, adding grip, drop protection, built-in magnets and a kickstand.

Galaxy S25: a leap from S22, not an automatic S23 or S24 swap

If you have a Galaxy S22 or older, the S25 offers a clear reason to upgrade: stronger performance, better battery efficiency and 6 major Android updates still ahead. Its Snapdragon 8 Elite ships globally and is the defining step forward.

A working Galaxy S23 or Galaxy S24 is another matter. If it still meets your needs, replacement is hard to justify. The notable exception is an Exynos S24 whose heat or battery life frustrates you; the S25’s Snapdragon 8 Elite gives you a concrete reason to switch. Otherwise, keep your S23 or S24 rather than upgrading for novelty alone.

Samsung Galaxy S25 refurbished: smarter value, same experience

What refurbished means for the Galaxy S25. A refurbished Galaxy S25 from refurbed is professionally tested, cleaned, and reset before it reaches you. Battery health is checked and verified. The grade shown on your listing reflects actual condition. A minimum 12-month warranty and 30-day free return are included as standard.

Android 16 in 2026, with 6 updates still to come. The S25 launched with Android 15 and is actively running Android 16 today. Six major Android updates remain. Buying a refurbished S25 now is not buying into a near end-of-life device. It is buying at the right moment in that device’s long software life.

Choosing refurbished over new makes a measurable difference. Based on research by Fraunhofer Austria, verified under ISO 14040/14044 standards, buying a refurbished smartphone instead of a new one avoids:

↓ 63.9 kg CO₂ SAVED, 83% fewer emissions (equivalent to approx. 447 km driven)
↓ 23,990 litres of water SAVED, 87% less virtual water (equivalent to approx. 160 bathtubs)
↓ 139.1 g of e-waste SAVED, 76% less electronic waste
↓ 33.4 g of critical raw materials SAVED, 63% reduction
↓ 1.12 g of conflict materials SAVED, 96% reduction

Samsung Galaxy S25 questions answered

Is the Samsung Galaxy S25 still worth buying in 2026?

Yes. Performance, software, and display are virtually unchanged compared to the S26. All three are also a step forward from the Galaxy S24. GSMArena’s lab verdict after head-to-head testing: ‘if you can live without the incremental upgrades, better go with the S25 and save cash.’ Refurbished pricing makes that case even stronger.

Should I buy the S25 or wait for the Galaxy S26?

Buy the S25 if you shoot 3x telephoto at night, want to save money, or the compact size matters to you. Buy the S26 if the extra 2 hours of battery life is essential or the improved selfie camera is important for your workflow. The performance gap in daily use is undetectable.

Will Galaxy AI features stay free?

Yes, confirmed still free in 2026. Call recording, transcription, and real-time translation are all active with no subscription. Samsung has indicated it may introduce pricing in future, but has not done so.

How does a refurbished S25 battery hold up?

After a full year of real-world use, independent reviews found the S25 battery still delivers a full day. On refurbed, battery health is checked and graded: the grade on your listing reflects actual capacity. A grade A or B unit performs like a new device.

Ready to get the Galaxy S25 for less?

Snapdragon 8 Elite performance, a compact form that most phones in 2026 have abandoned, and a software platform that keeps getting better. Available refurbished, the Galaxy S25 offers top-tier Android at a fraction of its original price.
