A friend of mine just bought a SX110IS camera and her battery life is aweful.
Initially she used the AA's that came with it and maybe got 40 pics before they died.
Then she bought some 2000mah NIMH AA's and was able to get about 50 pictures before the batteries died. She took mostly non-flash shots outdoors.
The manual says 400-900 shots on a charge of NIMH batteries, so this seems way off, even though I realize that they tend to exaggerate these numbers.
