My iPhone 5 last only 5 hours?

My iPhone 5 lasts only 5 hours of usage and then I have to put it on charge? Is this normal? Do I need a new battery?

Go into settings. Lower your screens brightness. The brightness eats up alot of battery. Also turn off bluetooth unless you need it. Lastly double press you home button and swipe up on your apps to close them so they don't run in the background. TIP - When charging, charge it off you will have a quicker charge and you will increase the life of your battery.

Ok lots of people make this mistake take they higher the brightness to full brightness, then they turn on ere blue tooth, then they ok in other words they have the phone doing everything in it's power running at one time. Turn it on with you need it and turn it off when you don't it will preserve the phones life time, and will save your batter for another 5 hours.
