*S21 numbers are based on leaks and rumors
An interesting observation here is that Samsung has narrowed the gap between the S21 Ultra and the S21 Plus. While the battery size on the Ultra has not changed from last year’s model, the S21 Plus has gotten a bigger 4,800mAh battery while at the same time that model remains considerably thinner. The Galaxy S21 Ultra is rumored to be 8.9mm thick vs just 7.8mm thickness on the Plus model, so the Plus might be a great option for those who want excellent battery life without having an extra large device.
