Thanks .. but the only thing that's eating my battery is the android os which is 77 percent .. how do I Lower it?!

With all due respect, if the OS is consuming 77% of the total power used, there may be very good reason why and it could easily be related to user-installed applications causing the OS to stall or work harder to take control of the device. It is not normal for the OS to consume this great of a percentage, and other than having a corrupt OS (which is highly unlikely unless it's a custom ROM that you have flashed yourself), I would again point to user-installed applications. By comparison, my RAZR has been on battery power for 5 hours, 50 minutes, and the Android OS has consumed only 22% of the total power usage. The Display was the big user at 31%. Right now, my battery is at 50% and in those 6 hours I have used it for multiple phone calls, emails, internet, Droid Forums App, and other purposes.
Common sense says if your device's hardware and OS is identical to millions of others out there (and you can assume it is unless you are running a custom ROM), and if your device is acting considerably differently than those others, there has to be something else that is causing it. The major variables in this equation are the applications you install, the services you connect to, and your personal usage patterns, along with the quality and availability of cellular and WIFI communications to access these services. It is a simple process of elimination that will point to the cause of your excess battery consumption.
As further evidence of the above, I recently ran into a situation where I couldn't install any apps if they were downloaded as APKs or if they were stored as part of a backup, yet I could install apps directly from the Market with no problems. I rebooted, uninstalled several apps I suspected, tried various troubleshooting processes, and cleared caches, all to no avail. Then I ran the Task Manager, selected ALL installed apps, set it to kill all tasks at 2 minutes after screen power-off, then proceeded to power the phone's screen of. In 5 minutes, I powered it back up, tried to install APKs from the SD Card and they worked without a hitch. Rebooted the phone, turned off the Task Manager, tried to install apps again and found it failed again.
So now I know it was an application that caused the problem and now I simply have to identify what app or apps are at the root of the problem. If I could have used Smart Mode, I would have but that would have disabled the ability to install any apps, so the next best thing was the Task Manager and fortunately - it worked.
