What's wrong with iphone battery?

I have an iphone 5 with t-mobile and the battery drains out fast, I'm already at 50% after 2 hours. What could the problem be?

Same reason why its a problem on Android, Blackberry, Windows… The more you make the phone do, the faster it dies…

Apple wants to be like Android… So… They copy-catted Android 4.0+ to make modern IOS, especially IOS 6 and 7… Omfg… Notifications? Widgets? Oh no, we made that ourselves… BS! LMAO!

anyways, your answer… Either…

reason 1) you have alot of background processes… Modify your app settings and kill some of these processes… Also take into affect screen brightness etc etc etc… More CPU and RAM = more battery power = more battery drain

reason 2) your battery is defective…

reason 3) your phone is defective

reason 4) nothing is wrong at all, but rather you are raping bandwitdh by user ALOT of media, games, radio, video, youtube, movies, etc… Media is the #1 data plan killer and ALSO the #1 battery drainer!

If you refuse to believe that this is all your fault, but rather its the phone… Then priove it… Do a itunes restoral… If issue is gone, then it was all your fault… Restoral restored factory settings and deleted All your settings… If issue persists, then you know 10000000000% the technology is failing… Replace the phone

Defected batter take it to the apple store or look online to see how to save battery.
