April 1, 2025Is Samsung S21 Ultra worth buying in 2025?
Actually, it is good. I am using it. But it cannot receive major OS updates which is major con. Pros is it is still snappy. Lag? Normal lag for a 4-year flagship. Yeah, just be sure it is in very good condition especially the screen. You can also look at LG V60, iP13 and Pixel 6 series. More on reddit.com

r/GalaxyS21 on Reddit: Is the Samsung Galaxy S21 worth buying in 2025? Pros and Cons, Battery Life?
April 1, 2025 -
Hey everyone, I’m thinking about buying the Samsung Galaxy S21 in 2025. I know it’s a few years old, but I’m curious if it’s still a good choice in terms of performance, camera, battery life, and overall value. Can anyone share their thoughts on the pros and cons of the S21 at this point? How is the battery life holding up after a few years, and does it still perform well for everyday use, gaming, and receiving updates?
