iPhone 3GS OS 3.1.3 Battery percentage fail?

Hi there!
I recently updated my iPhone 3GS from OS 3.1.2 to 3.1.3.
I've experienced some bugs with this update. I will try to explain everything sience my other phones camera can't capture good pictures to show the problem.
Here we go:
First I power up my iPhone. Then when it starts up the battery percentage shows me that the battery has 67 percent left. Now comes the bug. After some seconds the battery percentage meter CHANGES to 78 percent. This has never happend before I updated. I am very happy with my iPhone 3GS and I feel pretty disapointed with this update.
I find this highly unacceptable sience it has basicly ruined the user experience because I can no longer tell how much power my battery has left in percent.
I hope that Apple or someone reading this topic can help me with this problem.
Also if i restore my iPhone 3GS, will it delete all my apps and saved data from the apps like high scores from the game "Doodle Jump"?

Recalibrate the battery gauge by running the battery all the way down until the phone shuts off, then charge until full (preferably 4 hours).
