Extend your BlackBerry Smartphone battery life using these power saving tips by @rr_yy
[hr]
  • Delete unnecessary e-mail accounts from your device. I had 7 e-mail accounts before and now only 3 of them on my BlackBerry.
  • Use filters for your e-mail accounts.
    Ex: I filtered twitter and forum subscription e-mails so they are not coming to my BlackBerry anymore.
  • Led settings are important for battery life. Disable led for unnecessary notifications.
    Ex: I disabled leds for e-mails and Twitter.
  • Edit Twitter, BlackBerry News, Facebook, BeWeather (etc) auto refresh times.
    They were set to refresh every 5mins before and now I uninstalled Facebook (which I'm not using so much), set BlackBerry News & BeWeather to auto refresh every 6 hours and Twitter for every hour. (mentions and DMs coming right after they sent anyways)
  • Disable Browser Push; useless and affect your battery life.
  • Disable Browser JavaScript
  • Disable vibration for unnecessary notifications (I disabled them all)
  • Set Backlight Brightness as 10 and Timeout for 20 seconds (or 10 I got it set as 20)
  • Set your Network Mode as 3G or EDGE only. (2G&3G setting let your device search for network and affect your battery)
  • For OS 7.1 set Battery Saving Mode as Always On
  • Set Location Services Off
  • Disable Compression (Storage settings)
  • I got Cell Broadcasting disabled (not sure if it effects)
  • Uninstall unnecessary applications
  • Disable BePopup (etc) for e-mails (got it enabled for SMS only)
  • BlackBerry Protect location option is disabled for me because I got insurance for my device (but keep it on if you want)
  • BeBuzz led settings:
    - Slowdown Led: 1min
    - Stop Led: 2mins
    - Pause Between Flashes: 1sec
    - Pause Between Slow Flashes: 4sec
    - Pause Between Idle Flashes: 10secs
  • Close apps that you're not using. Don't let them run at background.
  • Delete MeterBerry and/or any other battery monitoring app. (use BlackBerry Device Analyzer for OS 7.1)
  • Before updating your device don't forget to shrink your OS w/ BBHTools. (ask for help for what to shrink if you don't know which are safe to shrunk)
