Samsung could decide to shake things up considerably with the Galaxy S21 Ultra. However, previously when we reported about the alleged battery capacity of the upcoming flagship, turns out Samsung might be retaining the same cell as it did on the Galaxy S20 Ultra. Any hopes of a change taking place could also be turned to ash because of the latest leak, so let us discuss more details here and talk about other ways in which the Galaxy S21 Ultra could become a compelling upgrade for customers.

The battery capacity was found out thanks to a 3C certification, and for those that don’t know, it’s a Chinese telecom authority. According to the details, the Galaxy S21 Ultra battery capacity is rated at 4,885mAh, meaning that its typical capacity will be around 5,000mAh. This means that the Galaxy S21 Ultra and the Galaxy S20 Ultra won’t be different in terms of cell capacity count, so Samsung will have to find other ways to make its upcoming flagship more energy efficient.
