The Galaxy S25 has a 4,000mAh battery and supports 25W wired charging. While Samsung claims better battery performance with the new Snapdragon 8 Elite chipset, that's not entirely believable. The S23 supports the same wired charging speeds and has a 3,900mAh battery.
Many people might reconsider if Samsung had packed a larger battery into the same compact form factor. But an extra 100 mAh isn't very appealing.
People are also disappointed that Samsung hasn’t adopted silicon carbide (SiC) battery technology. This new design allows for larger batteries in the same form factor. Other flagship devices like the OnePlus 13 have had success with this technology, and we’re hoping Samsung will adopt it in the S25.
The biggest thing Samsung is changing is that the Galaxy S25 is the company’s first Qi2 Ready device, which means it should offer better connectivity with wireless chargers. However, even this upgrade seems minimal, as the device itself isn’t Qi2 certified. Instead, you’ll need a specific case to take advantage of the feature.
A fully Qi2-certified device or another big battery upgrade might have convinced many to switch to the S25, but it looks like we’ll have to wait at least another year.
2. Performance is still great on the Galaxy S23

The Galaxy S23 still feels as fast and smooth as the day you bought it. Samsung shipped the S23 with the Snapdragon 8 Gen 2, and it still handles everything you throw at it with ease.
Apps open quickly, animations are smooth, and there's no noticeable slowdown. The S25 may be more powerful on paper, but you won't notice much of a difference in real-world use.
3. S23 will still be supported for many more years

So far, the Galaxy S23 has only received one major update – the upgrade from Android 13 to Android 14. However, with Samsung committing to five years of updates for older devices, the S23 still has plenty of time before you're forced to stop using it.
Sure, the Galaxy S25's seven years of OS upgrades sounds great, but the S23 still has four years of updates to go. That's more than enough to keep your phone fresh, making upgrading unnecessary at this point.
4. Camera improvements are not compelling enough

One of the main reasons people would want to upgrade to the S25 is because of the better camera for photos and videos. However, Samsung seems reluctant to upgrade the cameras on its base Galaxy phones, as it has kept the same camera for the second year in a row.
This means the Galaxy S25 has the same setup as the S23: a 50MP main camera, a 12MP ultra-wide lens, and a 10MP 3x telephoto lens. It also has the same 12MP selfie camera and can shoot up to 8K 30fps video from the rear sensors.
Samsung is promising better image processing on the S25, but without any actual hardware changes, those promises aren't enough to make people want to upgrade right now.
5. The best AI features are coming to the S23
Like many other smartphones these days, Samsung is leaning more toward software features and changes rather than focusing on major hardware upgrades. That includes the Galaxy's new AI features, most of which will come to older devices later this year, including the Galaxy S23.
Sure, users may have to wait a little longer to take advantage of new AI features like the improved Now Bar and Circle to Search, but so far, One UI 7 seems more exciting than the Galaxy S25 .
6. Galaxy S25 lacks must-have features

The Samsung Galaxy S25 feels more like a tweaked version of its predecessors than an exciting upgrade. It has the same overall design and battery life as Samsung's older Galaxy devices. Plus, the AI features that make it stand out are already available on older devices via software updates.
That leaves the Galaxy S25 without any must-have features, aside from being Samsung’s first Qi2 Ready device. But that’s not enough reason to upgrade to the S23, which still handles everything you throw at it perfectly.
With minimal changes over previous generations, there’s nothing truly groundbreaking here. The Galaxy S25 is a great option for those looking for a compact Android flagship. However, if you already own a Samsung flagship that’s a year or two old, the upgrade isn’t worth it. That’s why many will stick with the Galaxy S23 and hope for something truly exciting next year.
