Gionee recently marketed V188 Series / V183 and other products with high-capacity battery. The model, which carries the V381 name is no exception here as it was spotted on TENNA certification website.
As the data of Tenna suggests, Gionee V381 uses a 5-inch 960 x 540 resolution screen, it is equipped with the MT6732 1.3GHz quad-core processor. Also, it has 1GB RAM and 8GB of ROM, supports SD memory card expansion, has a camera combo of 2/8mp. Moreover, it has a support of GSM, TD-SCDMA, TD-LTE, LTE FDD networks and runs Android 4.4.4 system.
As far as design, the Gionee V381 reminds a bit of the Xiaomi and Gione Elife S5. However, because the device spots a massive 4200 mah battery inside the shell, it comes with a few disadvantages. The phone measurers at 144.2 × 71.0 × 9.5 mm and weighs 180g. Still, this downside should not bother you that much if you prefer a huge pack of power on the go.
