I have the S25u and have yet to go a day of heavy usage when I don't have any battery left. But there are people who report that issue (however, that's pretty much with every phone Samsung releases). That being said, with the new foldables expected to be released in July, prices (or at least offers) for the S25 will be better after that. The S26 is still 'too far' from release, but if you can wait, unfortunately it will likely be more expensive.
