The Samsung Galaxy S21 Ultra will have the same battery as the S20 Ultra; only the Plus model is in line for a larger battery
The Galaxy S21 Plus will be the only S21 series handset with a larger battery than its predecessor, according to GalaxyClub. The website has revealed that the Galaxy S21 Ultra will have a 5,000 mAh battery, the same capacity as the one that Samsung includes in the S20 Ultra. The battery, which Samsung has assigned the product number EB-BG998ABY, has a rated capacity of 4,885 mAh - the minimum performance of the battery.
The S21 Ultra should also bear the model number SM-G998, if the characters within the EB-BG998ABY battery product number are anything to go by. GalaxyClub adds that the battery in the S21 Plus will have rated and typical capacities of 4,660 mAh and 4,800 mAh respectively. From what we can tell, this battery is the EB-BG996ABY, which the 3C certified earlier this month. As we reported at the time, this battery should correspond to the S21 Plus having the model number SM-G996. The S20 Plus has a 4,500 mAh battery, so a switch to a 4,800 mAh battery for the S21 Plus is a modest upgrade at best.
As for the regular model, the 3C has also certified the EB-BG991ABY. Again, this should correspond to the model number SM-G991. This battery has rated and typical capacities of 3,880 mAh and 4,000 mAh, which would see the S21 match the battery capacity of its predecessor.
While the battery capacities of the Galaxy S21 series may disappoint, more efficient SoCs should help the three devices achieve better battery life than their predecessors. Samsung will probably release the Galaxy S21 series in Q1 2021, either in February or March.
