Torn between iPhone 17 and S25 Ultra

Both are roughly the same price where I live. I'm coming from an S23 that has horrendous battery life, so I'm definitely looking for an upgrade in that department. I own a Macbook and an iPad, so getting an iPhone would be a nice addition to the ecosystem. However I have concerns about the battery life on the 17. I have seen mixed opinions online. Which should I go for?
