Battery life

We ran the camera through our new battery life test. This test is designed to be fair and comparative to each camera and battery type:

- Take 4 shots without flash
- Wait 2 minutes (50% of the time powering the camera off)
- Take 1 shot with flash
- Wait 1 minute
- Repeat

All batteries had been fully discharged and recharged before the test and all cameras were reset to their factory default settings. Here are the results:

Other test notes:
• LCD monitor is left on during the battery test
• The camera is powered off half of the time and left on half of the time (switch every 10 iterations)
• There are now higher capacity AA NiMH batteries available, however in the interests of fair comparison we will continue to use our 1600 mAh test set.

I think it's fairly clear to see that Fujifilm's decision to switch from the NP-80 to four AA batteries was well justified. Battery life has been extended by an hour and is in fact one of the best performances we've seen from a camera which takes AA batteries.

You can find that Canon PowerShot G3 is the longest battery life / number of shots. But you can also note that the battery power of Canon PowerShot G3 is 8.1Wh (rather higher).


The battery life / number of shots is approximately proportion to the battery power (Wh). And since the battery power (Wh) is different for different camera, the number of shots cannot be compared directly. In order to compare the power consumption of each camera, I change the battery power of each camera to the same (8.6Wh) and convert the battery life and number of shots in direct proportional to battery power. The result is as follows:

Camera Battery Power Battery life Number of shots
Canon PowerShot S45 NB-2L 8.6 Wh 5 hr 26 mins 240
Fujifilm FinePix 6900Z NP-80 8.6 Wh 5 hr 12 mins 250
