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. That’s more than the 4,000mAh battery of the Galaxy A50, but less than the 5,000mAh battery of the Galaxy M20.

Unfortunately you have some serious text understanding issues. 2 batteries each with 2k+ mAh capacity will result in one with 4k+mAh total. You mistakenly added a third capacity to the total.
Not dumb at all, you shouldn`t compare an orange to a watermelon. You need to compare 2 phones with same battery ratings and see which one lasts longer. You know not every company has the battery optimization level of Sony.
