The Nokia 6300's short battery life is a very common problem, so it should
be good to know that you aren't the first to have to deal with this problem.
Here are a list of tips for stretching that battery life...
- Turn your bluetooth and GPRS off when you aren't using them
- Discharge the battery almost completely several times after charging it up, to help stretch the batteries life.
- Turn off any screen savers
- Use the red hang up button to turn the screen off because it works faster
- The more complicated solution is to buy a BL5-C battery and sand it down to fit, which i've heard many people have resorted to doing this
Also the common sense solution is... buy a second battery. It'll double your battery life overnight!
