With a smaller display, losing features and a more efficient chip, you would expect better battery life. However, based on Tom's Guide, the S21 Ultra is worse than the S20 Ultra. What's going on? Another major disappointment in addition to gutting the phone of features. Sure the adaptaprive display is better but that's apples to oranges. If you want to set the settings to the maximum battery life, the S20 Ultra takes the crown.
