i've had it wit the battery life and my last shot is restoring the phone to new, can this be done without losing info? i keep reading different facts about it. thanks

Restoring to new does exactly that.
Factory firmware is reinstalled and all personal info, files, and settings are erased.
You can always restore from a backup but then you risk recreating the problem that you were trying to fix with the restore.

If you do a restore like this will you be able to get your app data back, i am thinking of stuff like programs that store password data, or ones like evernote
