EDITORIAL: (this is a pre-test listing based on reasonable expectation of battery, screen and imaging performance) The second flagship Motorola phone comes with considerable increase in weight, size, processing power, battery, screen and price. Still present are industry leading drop protection, OS support length and desktop replacement functionality. If you're okay with its 77mm(3.03in) width, you need to consider getting this phone.

EDITORIAL: (this is a pre-test listing based on reasonable expectation of battery and imaging performance) On the day Qualcomm announced it's 2nm Snapdragon 8 Elite Gen 6 chip it got released in the latest Xiaomi phones. The 18 Pro Max gets the "Extreme" version that should deliver somewhat better performance across the board but 18 Pro will still beat the other competition. Unlike 17 Pro, the latest model is going global!
