The Zenfone is still significantly larger and heavier than the iPhone mini, which for me is already at the upper limit for one-handed use.
Weight and Dimension 169g, 148 x 68.5 x 8.9 mm
thats a full cm longer than the 2020 SE, which is already bigger than the mini. it might be "an answer to the mini" in features and spirit but not in size by far.
