The G810 employs a
1200 mAh Li-Ion cell, which, as the manufacturer claims, can keep the handset up and running for
250 hours in standby and be good for
2,5 hours of talk time. In Moscow the phone lasted roughly
2 days at around an hour of calls (total), some photos and video, and up 15 minutes of Web surfing a day.
This means that the G810 will last as least 2 days with average use, but you can also try to get 3 days out of it. Full charging time – 1,5 hours, give or take. High-capacity batteries are not available for the G810.
The GPS-navigation mode drains the battery clean in 2,5 hours.
We also managed to squeeze 10 hours of pure music playback time out of it.
