EDITORIAL: Motorola comes out with a hybrid: not quite a 8 Elite flagship in terms of processor speed or battery endurance but with a great camera, software, AI performance and build. The IP69 is supplemented with military-level drop protection, outstanding Bose-tuned sound system, excellent imaging and a very long OS support with a growing number of useful AI features.
PROs
flagship build with top drop protection, just 7mm thick, good SD 8 Gen 5 with UFS 4.1 performance, >30hr endurance from a 5200mAh Si-C battery with sub-45min 90W (50W wireless) charging, >1500nits bright 460ppi 165Hz LTPO AMOLED screen with Dolby Vision, excellent 50MP 23mm OIS main + 50MP 71mm OIS periscope telephoto + 50MP 12mm ultrawide (all with PDAF) back camera setup, excellent 50MP 21mm dual pixel PDAF selfie, good video recording, stock-like Android with excellent Motorola additions, up to 7 years of OS updates, lots of AI features along with a physical AI button, desktop replacement software, Bose-tuned speaker system, fast USB-C 3.1 Gen 2 with Display Port and OTG
CONs
limited market availability as with so many Motorola phones, unusual Pantene color choice, no expandable memory, rich AI features need some polishing

EDITORIAL: (this is a pre-test listing based on reasonable expectation of charging, screen and imaging performance) A year after it's first Pro Max phone Xiaomi knows it is ready for the international market. The new 18 Pro Max brings big upgrades in chip, massive 8500mAh battery, double 200MP lenses that replace the 50MP ones and a new HyperOS 4 with Android's native support for desktop replacement functionality. In the process, the phone grew in size and weight, now almost as big and heavy as it's iPhone competitor.
PROs
