iPhone v1.1.3 battery life giving you the blues? Try this…

How’s that freshly jailbroken v1.1.3 iPhone treating you? It’s pretty nifty, eh? Oh wait, what’s that? Battery life seems to have taken a nose dive? It’s okay. Take a deep breath and try these tips:

• Force-quit the iPhone Mail application everytime you’re done using it.
  Apple (NSDQ: AAPL) designed the iPhone to run all applications in the background (when you’re not using it). This allows for multi-tasking and a speedy application start-up time. However, it seems that some people are experiencing an iPhone v1.1.3 glitch whereby the Mail application is continually pinging the mail server, even between mail-check intervals. A force-quite of the Mail application should stop it from continually checking the mail server.
• Delete and re-sync all Mail accounts
  Your iPhone will sync Mail accounts with your computer (check the “Sync Mail Accounts” checkbox in iTunes), so deleting your iPhone Mail accounts isn’t that big a deal. After deleting, sync your Mail with iTunes and you may notice inproved battery life.
• Re-install/Restore iPhone firmware
  We know, we know. It was a pain in the you-know-where to get the jailbroken iPhone v1.1.3 up and running, but if you really feel that your current iPhone battery life is unacceptable, give the restore-option a go.
