Samsungs first foldable phone was reported to have two batteries, each with a capacity of 3,000mAh or more. Newer info points to a much smaller battery.
Two batteries with 2,190mAh capacity, 4,380mAh total, were spotted. They have model numbers EB-BF900ABU and EB-BF901ABU and are presumed to be the power units for the Galaxy F.
Battery info for the Samsung Galaxy A70 has surfaced as well. Its battery, EB-BA705ABU has 4,400mAh capacity. Thats more than the 4,000mAh battery of the Galaxy A50, but less than the 5,000mAh battery of the Galaxy M20.
The Galaxy A70 will be powered by Samsungs 10nm Exynos 9610 chipset (same as the A50) and will feature an AMOLED display, unlike most of the new A-series, which will use LCD.
The foldable Samsung Galaxy will be unveiled on February 20. Theres no official reveal date for the new A-series (the M-series is coming on January 28).
