Compare Mobile Phones Side-by-Side

The Apple iPhone Duo looks like the more ambitious device here. Its 7.6-inch 120Hz display gives it a much bigger canvas than the HMD Skyline G2, which matters if you watch a lot of video, multitask, read, or game on your phone. The 12GB of RAM also gives the iPhone Duo a clear advantage on paper for keeping apps active and handling heavier workloads.

The HMD Skyline G2 is the more conventional pick: smaller 6.67-inch 120Hz screen, nearly the same battery capacity, and a Qualcomm chip, but only 4GB of RAM. That memory gap is hard to ignore, especially for long-term use.

Unless you specifically want the smaller form factor, the iPhone Duo is the stronger-looking phone from these specs. The Skyline G2 may be easier to handle, but the Duo offers more screen, more memory, and a slightly larger battery, which makes it the more capable choice overall.
