    The battiery on the iphone is okay (6-10) the only problem is, is that you have to know how to use and perserive it! What i mean by this is, is that you should always turn off the screen when listening to music…Also try and plug in your headphones as much as you can as it reducces power wastage.Another thing is if you do NOT have the data plan and you use the wi-fi always keep it off when not in use- that goes the same with bluetooth because it always serches for new signels as it does need power for that…Another thing is go into your settings and adjuest your brightness settings as you do not always need it bright bright as most of the time you will be using it in the light…
