You can get a longer life by not looking at your pictures so often. If you do not need the flash, you can turn off the flash and this should also extend your battery life.
The Sony series ought to yield longer battery life as it is made from similar components as the Canon but is physically quite a bit larger.
Canon NB-4L should last 12 hours or longer.
The Canon PowerShot SD780 IS Digital ELPH battery lasts for about 350 shots.
Personally I think that Nikon is better than Canon, and it may be because I started out on a Nikon and have been on one ever since... but I truly believe that Nikon has a better quality and that it will last you much longer.
I think diz nuts last longer
keep the bright the lowest possible and turn off the wifi while not using the internet.
My friend has a Canon camera and is quite happy with it. I have found Canon cameras to be generally high quality and built to last. A good place to buy one would be on the website of a local electronics or camera store. Many of these sites will let you return or exchange in-store on the chance that you are not happy with your camera purchase.
the length of your battery time will depend on the length of time you are using your camera, if it is on constantly then it will only last several hours but if turned off it will last for many days
12hrs
If you want any batteries to last longer then put the batteries in your fridge and that helps them to last longer!!
he uses a canon camera windows 8.1 and last but not least digital clock
To save the battery buy Energizer lithium (the blue battery) ,this battery lasts the longest of all batteries.Also don't let the camera fall asleep because even though you don't see that it's on it still eats away the battery.
