Why is my iphone battery so bad?

I'm kinda mad because my iphone battery only lasts 5-6 hours of usage, and i used to get about 8 hours, i have brightness low, bluetooth off most of that stuff, and the only heat i had it in was i had it in my backpack while at the beach for a couple of hours, for a week.

If you've had it for like 6-8 months or more, the battery goes bad, but it happens quicker if you do quick charges. To preserve battery life, do full charges (4-5 hours at a time)
hope it helps!

Heat exposure can affect battery life. Also, are you playing apps or running programs a lot? That usually runs the battery down quicker. However I suggest going to your service provider since no one here can really give you a 100% answer. If something is wrong, hope you have insurance on your phone because repairs can be pricey!

Welcome to the iPhone! Aside from amazing apps, Siri, iTunes access, and more you get a horrible battery life.
