About the Samsung Galaxy S25

The Samsung Galaxy S25 is the compact flagship for people who refuse to compromise on power just because they prefer a smaller phone. Launched in February 2025, it packs the Snapdragon 8 Elite chipset into a sleek 162g body that is thinner and lighter than the S24, making it one of the most pocketable high-end Android phones available. The 6.2-inch Dynamic AMOLED 2X display remains sharp and vibrant with adaptive 1-120Hz refresh rate, and Samsung has resolved the low-brightness graininess that affected the previous generation. Camera hardware carries over from the S24 with a capable 50MP main, 12MP ultrawide, and 10MP 3x telephoto setup, but the new chipset brings improved image processing and AI-powered enhancements through Galaxy AI. Battery life holds steady at a full day from the 4,000mAh cell, though charging remains at 25W wired. The real story here is the Snapdragon 8 Elite, which delivers a 37% CPU improvement and 30% GPU gain over the S24, making everything from app launches to gaming noticeably snappier. With seven years of software updates and a refined One UI experience, the Galaxy S25 is Samsung's best small flagship yet.

Frequently Asked Questions

Is the Samsung Galaxy S25 worth buying?

Yes, the Samsung Galaxy S25 is worth buying if you want a compact, powerful Android flagship. The Snapdragon 8 Elite chipset delivers a meaningful performance leap over the S24, Galaxy AI features add genuine productivity value, and seven years of updates ensure long-term viability. It is especially good value if you are upgrading from an S23 or older model.

What processor does the Samsung Galaxy S25 use?

The Samsung Galaxy S25 is powered by the Qualcomm Snapdragon 8 Elite chipset, which features two high-performance Oryon cores clocked at up to 4.47GHz and an Adreno 830 GPU. This represents a significant upgrade over the S24's Snapdragon 8 Gen 3, delivering approximately 37% faster CPU performance and 30% faster graphics.

How good is the Samsung Galaxy S25 camera?

The Samsung Galaxy S25 features a triple camera system with a 50MP main sensor, 12MP ultrawide, and 10MP telephoto with 3x optical zoom. While the hardware is unchanged from the S24, the new Snapdragon 8 Elite chip improves image processing, low-light performance, and AI-powered features. It produces excellent photos for a phone at this size and price.

Does the Samsung Galaxy S25 support wireless charging?

Yes, the Samsung Galaxy S25 supports wireless charging at up to 15W, along with 25W wired fast charging and 4.5W reverse wireless charging. A full wired charge takes approximately one hour and twenty minutes from empty.

How long will the Samsung Galaxy S25 receive software updates?

Samsung guarantees seven years of Android OS upgrades and security updates for the Galaxy S25. This means the phone will be supported through to at least early 2032, matching the update commitment of Apple's iPhones and making it one of the longest-supported Android devices available.

Should I upgrade from the Samsung Galaxy S24 to the Samsung Galaxy S25?

For most S24 owners, the upgrade is hard to justify. The main improvement is the Snapdragon 8 Elite chip, which is noticeably faster, but the camera hardware, battery capacity, and charging speed are unchanged. If you are coming from an S23 or older Galaxy, the S25 represents a much more compelling upgrade.

Is the Samsung Galaxy S25 Ultra worth it over the Samsung Galaxy S25?

The biggest difference is the camera: the S25 Ultra has a 200MP main sensor and 50MP ultrawide versus the S25's 50MP main and 12MP ultrawide, plus it adds a 5x telephoto and a built-in S Pen. You also get a larger 6.9-inch QHD+ display, 5,000mAh battery, and faster 45W charging. The S25 Ultra starts at £1,249 SIM-free vs £799 for the S25, so the S25 is the smarter pick unless you need pro-level cameras or the S Pen. Compare Samsung Galaxy S25 Ultra deals.

Older flagships are de-rated since image processing pipelines have advanced significantly each generation. Megapixel count is deliberately downweighted — it correlates poorly with real-world camera quality.

Based on battery capacity (mAh) adjusted for platform efficiency calibrated against NotebookCheck, Tom's Guide, GSMArena and CNET reviewer tests. Apple A-series gets +45% (iOS process freezing + LTPO 1Hz + tuned panels make iPhone Pro Max outlast many 6500+ mAh Android phones in measured tests). Top Snapdragon / Dimensity flagships get +15%, budget chipsets are penalised −15% to −25% to reflect less efficient displays and looser background limits. Charging speed is excluded — see the separate Fast charging tag for that.
