I've been waiting until I've gotten a few charges under my belt before writing about this. I get an average of about 120 shots per battery charge. This is without flash, and with the LVF on, using the LCD maybe every so often to review shots. I have the sleep and review settings pretty short. I'm also in California, where it's been in the 50s and 60s out, so no cold temperature effect. I do not shoot that many shots at once, and I wonder if this may be one explanation. That 120 shots equals about 10 days of use. (Or perhaps 10 days of not being used.) So, I'm not thrilled with the battery life. Also, I've noted that once the battery indicator goes down one notch, there will not be very much power left. (I still have and use a Sony S85 that tells you, very accurately, how many minutes of battery life are left. This is about 8 years old.) What are other's experiences with the GF1 battery life? Any tricks to getting more time out of it? My assumption is that this is not a battery that needs to be "trained" or have its charging carried out in a specific manner, but I could be wrong.
