I know some of you who only buy flagships were unimpressed with the iPhone 16 and felt the Pixel was “meh.” You have no place for a Google-less tri-folding Huawei and don’t trust any other brand. Who are we kidding? We have a large number of loyal Samsung fans who would never buy anything else. This one’s for you.

I know you’re looking forward to the launch of the Samsung Galaxy S25 series in just a few weeks. We now have some confirmed specs on these phones, and here’s what you can look forward to.

Where we got the confirmation

In many countries, electronic devices that use radio frequencies (like smartphones with Wi-Fi and cellular connectivity) must receive approval from regulatory bodies before they can be sold.
This process involves submitting documentation (and sometimes the device itself) for testing to ensure compliance with safety and electromagnetic interference standards.

With the S25 series only a few weeks away from launch, Samsung submitted documentation to the US regulatory body, and it is this listing that made its way into the public’s hands.

What was confirmed

I guess we can start with the fact that there will be three devices: the S25, S25 Plus, and S25 Ultra. They are all still flagships and will have the features you’d expect on such devices.

In a recent conversation, I realized some people may not fully understand what some of these features are about. So, I’ll briefly explain the more obscure confirmed details.

Wi-Fi and Cellular Connectivity

The S25 series will have 5G, NFC, and:

Dual-band Wi-Fi: This means the phones operate on two frequency bands, 2.4GHz and 5GHz. The 2.4GHz band offers wider coverage and better penetration through walls, while the 5GHz band delivers faster speeds and reduced interference for bandwidth-heavy tasks. Fortunately, dual-band Wi-Fi is now common, even on budget devices.
Dual-band GNSS: Global Navigation Satellite System technology lets your phone pinpoint its location using multiple systems like GPS, GLONASS, Galileo, and BeiDou. Dual-band functionality enhances accuracy, reduces interference, and performs better in tricky environments. Most budget devices stick to single-band GNSS, which is less precise.
Bluetooth: While not confirmed, the S25 is likely to feature Bluetooth 6.0. You can read about the benefits of 6.0 vs older versions of Bluetooth here. Flagship phones almost certainly will have it, while midrange and budget devices may not.

Charging

At this point, we shouldn’t expect Samsung to improve its charging technology. Documentation shows the S25 will charge at a maximum of 25W, the same as the S24 and even the S20.

While charging speeds remain consistent, improvements in battery efficiency and thermal management enhance the overall experience. Still, faster charging would’ve been nice—especially with brands like Realme offering 320W charging that tops up a phone in under 5 minutes.

The S25 Plus and S25 Ultra aren’t much better, charging at a maximum of 45W, as they have for years.

On the bright side, reverse wireless charging is improving. The S25 will offer 9W reverse wireless charging, up from 4.5W, making it faster to top up your earbuds or smartwatch.

The New Stuff

We expected all of the above, but the S25 Plus and S25 Ultra will also feature UWB (Ultra-Wideband) support.

UWB uses radio waves to pinpoint the exact location of other UWB devices with incredible accuracy (within a few centimeters). This allows features like keyless car entry, finding lost keys, or sharing files by pointing your phone at another device.
UWB is still considered a premium feature, so it’s reserved for the Plus and Ultra models. The standard S25 won’t have it.

As you can see, there isn’t much to get excited about from the confirmed specs. Rumors suggest all three devices will be powered by the Snapdragon 8 Elite chip globally—fingers crossed for that.
