i tot the battery can lst quite long one?..
Depend how u use ur phone lah, the phone standby currently only use ~3mA mah...
QUOTE
1. Phone in standby (gsm), no wifi/bt, screen not lid and phone in lock mode
Current measure: Average 3mA through out the day, 1320mAH/3mAH=440 hours.
2. Phone in use, no wifi/bt, screen lid (75%) and phone in unlock mode
Current measure: Average 160mA within 1 hour, 1320mAH/160mAH=8.25 hours.
screen brightness: 100% > 210mA = 1320mAH/210mAH=6.29 hours
screen brightness: 75% > 160mA (different: 50mA) = 1320mAH/160mAH=8.25 hours
screen brightness: 50% > 120mA (different: 40mA) = 1320mAH/120mAH=11 hours
screen brightness: 25% > 110mA (different: 10mA) = 1320mAH/110mAH=12 hours
screen brightness: 0% > 95mA (different: 15mA) = 1320mAH/95mAH=13.89 hours
3. Phone in call mode, no wifi/bt, screen off (sensor) and phone in calling mode
Current measure: Average 165mA within 10 mins, 1320mAH/165mAH=8 hours.
4. Phone in standby (gsm), wifi/bt ON (active), screen not lid and phone in lock mode
Current measure: Average 40mA within 10 mins, 1320mAH/40mAH=33 hours.
5. Phone in standby (gsm), wifi/bt OFF, GPS ON, screen not lid and phone in lock mode
Current measure: Average 80mA within 30 mins, 1320mAH/80mAH=16.5 hours.
From these result we can say the phone will dead easily if you navigating because the screen will lid and the GPS is on which will consume 240mA not include those heavy calculation and voice feedback this make the average navigation from fresh charge can last +/- 5 hours. Other setting like video capture, music playing and photo shoot also consider heavy load on the device but only if someone can do the measurement while I'm done here.
People easily got confuse saying device power hungry but if we really calculate how we use the device it all will add up (come on those wattage won't just dissapear in air)
Overall I can say the device done very well on it's standby current usage (3mA) this is out standing coz your phone still alive while only 3mA been supply to all it's hardware.
