Andrew is CNET's go-to guy for product coverage and lead photographer for Europe. When not testing the latest phones, he can normally be found with his camera in hand, behind his drums or eating his stash of home-cooked food. Sometimes all at once.
As rumors predicted, the base S21 will have a 4,000-mAh battery powering its 6.2-inch screen. The S21 Plus will increase that size to 6.7 inches and in so doing will squeeze a higher capacity 4,800-mAh battery inside. The S21 Ultra will be the biggest of the three at 6.8 inches and will pack a 5,000-mAh battery.
That's pretty much in line with the battery sizes used in the S20 series: The base model S20 has a 4,000-mAh cell and the S20 Ultra ups that to 5,000 mAh. We hope to see similar performance when it comes to battery life. You probably won't struggle to get through a day with careful usage, but streaming video for ages and taking lots of photos and videos will likely mean you'll need to recharge in the evening. As always, we'll be putting the
through our usual array of battery tests when we get hold of them.
