Battery Life
One of the standout features of the Gionee Marathon M4 is its massive 5000 mAh non-removable battery, which was a significant selling point. Official specifications promise stand-by times of up to 400 hours on 3G and talk time of roughly 18 hours on 3G. In practical use, this translates to impressive battery life, easily lasting more than a day with moderate use, and well up to several days for more conservative users.
