Samsung Galaxy S27 Ultra and S27 Pro batteries pictured in a new certification
The Galaxy S27 Pro and Galaxy S27 Ultra have 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's SM-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.

Thankfully, we already know them. The capacities first leaked back in July, and China's 3C certified 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 the Galaxy 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 reportedly tested a 7,000 mAh prototype before settling on a smaller cell to keep the S Pen. It's still unclear exactly when the S27 series will launch, though a recent report suggests Samsung may return to its usual January/February time frame.
