The Galaxy S5 improves on its predecessor in multiple ways, including a water-resistant design, fingerprint reader and even a heart rate monitor. But this powerhouse can also get you through the day. The T-Mobile version of the S5 lasted a whopping 10 hours and 57 minutes on our battery test. The AT&T (9:28) and Sprint (8:34) models also delivered great endurance. The Verizon S5 lasted 7:30, which is still above average.
