If you are getting poor battery life here is a very good clear and concise list posted by Lawrence Finch.
Many people have had suscess in fixing fast battery draining issues by following these some or all of these steps
There is some process that is using the battery when the phone is idle. It is not a problem specifically with 4.2.1, it can happen with any version, and at any time. It IS more common after an upgrade, however. you need to identify the process that is causing the problem. There are several things to try to resolve it. Be sure to reboot (hold HOME and SLEEP until an Apple logo appears, about 10 seconds) after each step. Test after each step and if the problem is resolved do not go further.
1. Go to Settings/General/Reset and Reset Network Settings.
2. Go to Settings/General/Reset and Reset ALL Settings.
3. If you have a Push email account or accounts, go to Settings/Mail,Contacts,Calendar, tap on the push account name and turn if off with the switch. (Turn off the ACCOUNT, not PUSH). Next open the email app so it "knows" the account is off. Quite email. After the reboot go back into Settings and turn the account(s) back on.
4. Close all Safari pages.
5. If you have used Game Center at any time in the past, go to Settings/Restrictions and enable the restriction on Multiplayer games. You will have to assign a lock code. DO NOT FORGET IT!
6. If none of these have helped Restore the phone in iTunes.
7. If that does not fix it Go to Settings/General/Reset and Erase All Contents and Settings. Restore again, but this time set up as a new phone.
If you have gotten this far the phone should be working normally. If it still is not you most likely have a hardware problem.

hi vieaba they always say that even when you come out of your apps it never completely shuts down, & that it's still running in the background,
Not true. The only apps that "run in the background" are a handful of audio streaming and Nav apps, and it's self evident that they're running.
The vast, vast majority of apps are either frozen in the last opened state (iOS 4 compliant) or conventionally closed and use no CPU or battery whatsoever, regardless if they appear on the "recently opened" (AKA multitasking) bar.MacPro4,1 8 Core, MB Air3,2 (13"), Mac OS X (10.6.6), iPhone 4, iOS 4.2.1, iPad 3G iOS 4.2.1, AirPort Extreme, 160GB iPod

When I was having the Same problem with Standby and Usage Times and a very short Battery Life… I tried the usual fixes...
The Only thing that eventually Worked (for me) was to do a Restore as New…
Very Easy and Straight Forward… and the phone has been performing Brilliantly ever since… ( nearly a month now…)
Also, once a week, I make sure to run my Battery right down (5%) and then Recharge over night…
Hope this Helps,
