Confirmed Features on the Upcoming Samsung Galaxy S25
The much-anticipated Samsung Galaxy S25 series is set to hit the market with several significant improvements, according to a recent listing submitted to the US regulatory body. The new devices are expected to offer superior Wi-Fi and cellular connectivity, faster charging speeds, and Ultra-Wideband (UWB) support.
Wi-Fi and Cellular Connectivity
The flagship Galaxy S25 Ultra will support advanced Wi-Fi 7 standards, including 802.11ax/be in 2.4GHz, 5GHz, and 6GHz bands. This upgrade, coupled with EHT320, MIMO, and 4096-QAM modulation, promises a substantial improvement in speed and stability over previous generations. For cellular connectivity, the device will support a broad range of 4G LTE bands, along with extensive 5G Sub6 and TDD Sub6 bands, ensuring global connectivity.
Charging
Samsung is rumoured to boost the charging speed for the S25 series significantly, potentially surpassing the previous 45W cap. Leaks suggest the charging speed might reach around 60-65W, enabling faster recharge times of around 30-45 minutes for a full charge, depending on the exact wattage used.
Ultra-Wideband (UWB) Support
The Galaxy S25 Ultra will notably include UWB technology, which offers highly precise spatial awareness. This feature enhances device tracking, smart home interaction, and secure device-to-device communication. UWB is a premium feature, so it will be reserved for the Plus and Ultra models.
Additional Features
The S25 series will also feature dual-band GNSS technology, including GPS, GLONASS, Galileo, and BeiDou, for improved accuracy and reduced interference. The devices will have 5G, NFC, dual-band Wi-Fi, dual-band GNSS, and likely Bluetooth 6.0. The standard Galaxy S25 will not have UWB support, but the S25 Plus and S25 Ultra will.
The S25 series will charge at a maximum of 25W, the same as the S24 and S20, and offer 9W reverse wireless charging, up from 4.5W. However, there is no information available about any changes to the battery efficiency or thermal management in the S25 series.
Rumours suggest all three devices in the S25 series will be powered by the Snapdragon 8 Elite chip globally. UWB allows features like keyless car entry, finding lost keys, or sharing files by pointing your phone at another device.
The Samsung Galaxy S25 series consists of three devices: S25, S25 Plus, and S25 Ultra. The S25 Plus and S25 Ultra will charge at a maximum of 45W. Dual-band Wi-Fi operates on two frequency bands, 2.4GHz and 5GHz, offering better coverage, penetration, and faster speeds. UWB uses radio waves to pinpoint the exact location of other UWB devices with incredible accuracy (within a few centimeters).
Gadgets such as the smartphones in the Samsung Galaxy S25 series, including the S25 Ultra, are set to benefit from advances in technology, offering superior Wi-Fi connectivity that utilizes upcoming Wi-Fi 7 standards, Ultra-Wideband (UWB) support for enhanced device tracking and interaction, and potentially faster charging speeds of around 60-65W for the flagship models.
These new devices, like the Galaxy S25 Ultra, also employ Dual-band Wi-Fi for better coverage, UWB for precise spatial awareness, and a range of cellular connectivity options such as 4G LTE, 5G Sub6, and TDD Sub6 for global connectivity.
