There are some slight differences between these two watches. The XGO3 is our basic product, while the X5 Play is part of our premium line.
The X5 Play has a better chipset (Qualcomm vs. Unisoc W307) and it also offers better connectivity as it connects to more frequency bands than the XGO3. The X5 Play has a slightly bigger screen and it allows you to record videos, while the XGO3 has the same screen resolution, but you can currently only take pictures with it. The X5 Play is operated by Android while the XGO3 is operated by RTOS. The X5 Play has more memory (RAM 512 MB + ROM 4GB vs. RAM 128MB + ROM 128MB), but the XGO3 has 50 mAh more battery capacity. For the location, in addition to WiFi and cell tower data, the X5 Play uses GPS, while the XGO3 uses GPS + BDS.
