Samsung's upcoming Galaxy S27 Ultra and S27 Pro to feature larger batteries
Regulatory filings reveal the Galaxy S27 Ultra will have a 5,700 mAh battery and the S27 Pro a 5,200 mAh unit, marking a notable increase over the previous model.
Regulatory approval documents show that Samsung's forthcoming Galaxy S27 Ultra will be equipped with a 5,700 mAh battery, up from the 5,000 mAh cell used in the Galaxy S26 Ultra. The smaller Galaxy S27 Pro is listed with a 5,200 mAh battery, suggesting a modest but meaningful capacity boost for the mid-range variant.
Analysts note that Samsung has historically been cautious about expanding battery size and fast-charging capabilities, prioritizing safety and longevity. The new capacities indicate a shift toward longer-lasting devices, potentially extending usage beyond a single day on a charge.
