My bb 9790 bold only last 5 hours or less in battery life, is it normal?
Five hours is on the moderate to low side.
But with better application usage management such as closing apps not in use, you may get better battery life.
The most important practice you can adopt is to be sure to CLOSE applications when you are finished using them.
If you just hit the red "end call" key to go back to the home screen the application actually stays open and running in the background, and that will drain the battery. If you do this repeatedly you will have lots of apps open and consequently your memory will get used up. Lack of memory is the biggest reason your BlackBerry slows to a crawl or locks up. If you get into the habit of actually using the menu key to close the applications this will at least slow down this memory-clogging process. You still may have to do a battery pull or use the "Quickpull" app once in a while when things get slow.
To check what applications are running on your device in the background, press the Menu key then choose Switch Applications. You will see the icons of each application there.
So now, check your applications running in the background. There are commonly four or five applications that will always be running (Messages, Call Logs/Phone, BlackBerry Messenger, Homescreen, and the Browser; there are other third party applications such as BeeJive, and BlackBerry Alerts which will also run in the background which you cannot close if you want them to operate). Make certain that the browser is NOT on an active webpage (open the browser and choose Menu > Close). Close any other applications that do not need to be running (the camera or a game you were playing or Google Maps).
