Summary
- The Lenovo S939 features a larger 6.0-inch IPS LCD display with a resolution of 720 x 1280 pixels, while the ZTE Blade A31 has a smaller 5.45-inch IPS LCD with a higher resolution of 720 x 1440 pixels, resulting in a denser pixel density.
- In terms of performance, the S939 is powered by a Mediatek MT6592 chipset with 8GB of RAM, compared to the ZTE's Unisoc SC9863A with 2GB of RAM, which may affect multitasking capabilities.

- Battery capacity is the same at 3000 mAh, but both lack fast charging and wireless capabilities.
- The S939 runs on an older Android 4.2, while the Blade A31 benefits from a more recent Android 11 (Go edition), enhancing the software experience.
