Our take
Its 7,300 mAh battery lasted 25 hours 13 minutes in Tom's Guide's battery test, nearly seven hours longer than the iPhone 18 Pro Max and the longest of any phone they tested. TechRadar gave it a perfect score and called it the best battery life its reviewer had experienced.
The trade-offs: weaker night photos than Apple, Google and Samsung, shorter update support, and no Qi2 magnetic charging. 512GB is $999.
