BEST Battery Life Phones in 2025 (TESTED + RANKED!) | Tom’s Guide Battery Test

John V. is back again with the end of year results of the Tom’s Guide Battery Test, ranking the best phones for battery life based on our official benchmarks. All of the smartphones on this list launched in 2025, and while these aren’t our rankings for the best phones of the year overall, this list hones in battery life performance. Some are flagship handsets you’ll definitely recognize like the iPhone 17 Pro and Galaxy S25 Ultra, but then we’ve got Moto G 2026 and even the Razr Ultra. It was a very good year for OnePlus when it comes to battery life testing, too!
