How can I improve the battery life on my Pre?

There are several ways to get the most battery life from your Pre. Below are a few helpful tips:

Turn off GPS: If you don't frequently use GPS, go into location preferences and turn it off when not needed.
Turn off bluetooth: Bluetooth usually drains battery faster than normal, so turn it off to maximize runtime.
Close apps: Having many apps open, especially third-party ones, can potentially contribute to battery drain. Flick them away when you don't need them.
Perform a soft reset: Like any device, a soft-reset can work wonders, especially after extended usage. Hold the power button down while toggling the ringer switch three times.
Find a better signal: With a poor signal, the Pre has been known to drain battery trying to hold a good connection. If possible, move to a room with a better signal.
Log out of IM / Exit Hotmail: In early units, this has been known to have a negative effect on battery life. Log out of IM and close hotmail when not in use.
Use Wifi or turn it off: In areas of lower coverage, use Wifi if possible to save a poor 3G signal from draining battery (and to increase speed). When 3G coverage is strong, turn Wifi off.
Carry a spare battery and car charger: If you still need more battery life for extended trips, consider an extra Palm Pre battery or car charger from the Palm store.
