Battery Life
With its 3100 mAh non-removable Li-Ion battery, the Hero 2 promised decent longevity under moderate use. Official figures suggested up to 500 hours of standby time and around 15 hours of talk time on 2G, with slightly less endurance on 3G networks, reflecting the energy demands of the large display and octa-core processor. While not groundbreaking, the battery life would typically suffice for most daily activities without needing frequent charges.
