Just stumbled on this solid guide to conserving battery life on mobiles. One of BlackBerry’s big selling points is killer battery life, but that’s no excuse to get lazy – you can stretch it even farther by following some of these easy-to-remember tips. A no-brainer is to turn off extra wireless functions like Bluetooth, Wi-Fi, GPS or dual-mode roaming on the World Edition, and turning off vibrating alerts.
Some lesser-known tips include only using your BlackBerry in areas where you have a strong signal, since more battery life is used up trying to establish connections over weak signals. Initializing a new battery with 5-6 hours of juice before using it should also increase the maximum capacity in the long run. The guide also suggests cleaning battery contacts every once in awhile in order to keep power transfer optimized. There’s plenty more there, so take a look.
