Samsung Galaxy S27 Ultra and S27 Pro batteries pictured in a new certification

TheGalaxy S27 ProandGalaxy S27 Ultrahave been making the certification rounds for a while now, and their batteries have just shown up in the Safety Korea database, complete with photos. The batteries have the model numbers EB-BS957CBY and EB-BS958DBY, which line up with the S27 Pro's and S27 Ultra'sSM-S957 and SM-S958 model numbers, and both are made by Zhuhai CosMX Power in China. Unfortunately, the capacities aren't legible in the photos. Samsung Galaxy S27 Ultra (left) and S27 Pro (right) batteries at Safety Korea

Thankfully, we already know them. The capacitiesfirst leaked back in July, and China's 3Ccertified them in September. The S27 Ultra's battery has a rated capacity of 5,534 mAh, which should translate into a typical 5,700 mAh, while the S27 Pro's is rated at 5,087 mAh, likely 5,200 mAh typical. Both phones are certified for 60W wired charging, just like theGalaxy S26 Ultra. If those typical figures are right, the S27 Ultra will have 700 mAh (14%) more than the S26 Ultra's 5,000 mAh, and even the smaller S27 Pro will beat it by 200 mAh (4%). Samsung has stuck with 5,000 mAh on its Ultras for years, and it reportedlytested a 7,000 mAh prototypebefore settling on a smaller cell to keep the S Pen. It's still unclear exactly when the S27 series will launch, thougha recent reportsuggests Samsung may return to its usual January/February time frame. Via
