Ever since Qualcomm unveiled the Snapdragon 888 processor, there have been rumors and speculations about Samsung going full Exynos with the Galaxy S21 series. However, that doesn't appear to be the case. The Galaxy S21 series will indeed come equipped with the Snapdragon 888 chipset, at least in some markets.
The Galaxy S21 (SM-G991U) received the FCC certification yesterday, and the supporting documents reveal that the phone will use the SM8350 chipset. This is the codename for the Snapdragon 888 processor from Qualcomm. It means that the Galaxy S21 (and other smartphones in the series) will use the newest Snapdragon chipset in the US. It is rumored that Samsung will release the Snapdragon 888 variants of its upcoming flagship smartphones in South Korea and the US, while other markets will get the Exynos 2100 variants.
The FCC certification also reveals that the Galaxy S21 will feature mmWave 5G, Wi-Fi 6, Bluetooth 5.0, NFC, and 9W reverse wireless charging. The Galaxy S21's battery (EB-BG991ABY) was also mentioned in the document, but its capacity wasn't revealed. However, the battery's 3C listing had earlier revealed its capacity to be 4,000mAh.
While the FCC certification also mentions a charger with model number EP-TA800, we can't be sure if Samsung will bundle it with the Galaxy S21. It is a 25W USB Type-C fast charger that comes with the company's current-generation mid-range and flagship smartphones. It is being reported that the Galaxy S21 series might not come with a charger and earphones in the box.
