Turn your phone off (or change to "Offline" profile): If you're in an area with no signal for a long period of time. Smartphones (N97, 5800XM etc.) shouldn´t be turned off, because this´ll take more battery than to keep them on and change to "Offline" profile.
Fully discharge from time to time: There is no problem in charging the battery often, although you can improve your battery indicator and the the battery life, by discharging it every 15-20 charges in order recalibrate it.
Set a dark theme: Displays consume more energy when bright colors are shown. Use dark themes and wallpaper images in your device.
