Looking for an iPhone with long battery life? Here Are the Best in 2025
If you’re shopping for a new iPhone or a refurbished one, you’re probably wondering, which iPhone has the best battery life in 2025? Whether you’re a heavy user or just tired of midday charges, battery performance is a deal-breaker.
And while the latest iPhone 16 series is out now, newer doesn’t always mean better. In fact, some older iPhone models still outperform in real-world usage, especially the Pro Max and Plus variants.
So, before you hit that checkout button, here’s what you need to know.

Plus, with the rising quality of refurbished iPhones, you can now get a like-new device with a fresh battery at a lower price.
