UMIDIGI Z1 Pro Review

Overview

UMIDIGI Z1 Pro has been marketed as the world's thinnest big battery smartphone. While we'll discuss its dimensions and weight in the design section of this review, it is worth noting that a 4000 mAh battery cannot be considered "big" when for the past two years there have been smartphones with 6000 mAh, 10000 mAh, and now even a 12000 mAh-battery smartphone is coming up. Another major selling point is the AMOLED display, which is a big thing as we're talking about the mid-range segment here. Finally, the model has two rear cameras, which should be another feature to lure customers. It is always worth making an in-depth review of an UMIDIGI smartphone as they have a history of good smartphones with controversial features and qualities. Of course, we will check every single detail about the Z1 Pro we can and see if it delivers what it promises.
