We are just two months away from the launch of the Galaxy S23, and some of its features have already leaked. The design renders of all three phones in the series have also leaked. Now, the priciest phone in the lineup, the Galaxy S23 Ultra, has received FCC certification ahead of its launch.
The Galaxy S23 Ultra received the FCC certification two days after the Galaxy S23 and the Galaxy S23+ received it. The phone has the FCC ID A3LSMS918B. It is the international variant of the smartphone, and it seems to be missing two important upgrades. As per FCC's certification documents, the Galaxy S23 Ultra still uses 25W charging (EP-TA800) and has Wi-Fi 6E (802.11ax). However, you should take this information with a grain of salt as it might not reveal the full picture.
Galaxy S23 Ultra's FCC certification might not reveal the complete picture
Samsung usually tests its phones with the same 25W charger even though the devices support faster charging standards. Similar was the case with the Galaxy S22+ and the Galaxy S22 Ultra, as they support up to 45W charging, but their FCC certification only listed the 25W EP-TA800 charger. Moreover, it has been widely rumored that the Snapdragon 8 Gen 2-equipped Galaxy S23 series will be among the first phones to feature Wi-Fi 7 (802.11be). So, more accurate information could be revealed by its Wi-Fi Alliance certification.
The Galaxy S23 Ultra's battery (EB-BS918ABY) is listed in the FCC database, and it was revealed a few weeks ago that it has a 5,000mAh battery. So, you shouldn't expect the smartphone to have a bigger battery than the Galaxy S22 Ultra. The battery is manufactured by Samsung SDI, Samsung's battery manufacturing arm. The certification also reveals that the Galaxy S23 Ultra is compatible with the S-Pen (EJ-PS918), which features Wacom's technology.
Samsung is expected to bring various smaller improvements with the Galaxy S23 Ultra, including a much faster Snapdragon 8 Gen 2 processor globally, a bigger 3D Sonic Gen 2 fingerprint reader, an improved front-facing camera with OIS, faster Bluetooth and Wi-Fi, and more durable glass protection for the display and the camera lenses. The biggest upgrade would be the 200MP rear-facing camera, though, which can take some amazing images.
