I got a new S21 Ultra this week. I was disappointed with battery life initially, but have been letting it bed in and learn my usage. I'm still not happy - compares poorly to my old P30 Pro.
The phone was bought from Samsung, a clean UK install, latest firmware, and I've attached a screenshot of the first battery report post calibration - limited 5G usage, but nothing major running apart from that huge screen and a bit of Spotify.
Is this what others have been experiencing? I am minded to return - my results are out of line with the reviewers. I'm not interested in tinkering with the screen or brightness - for this price my view is it should just work.
And - thinking out loud here - could phone companies be jiggering their review models' battery life to give better results, like VW did with the emissions scandal?
