Why does my iPhone 5 battery drain so much

My iPhone 5's battery battery goes down 20% in like 2 minutes just from web surfing without Wi-Fi. When I have Wi-Fi enabled it goes down 30% - 40% in like 2 minutes. Other times, I leave my iPhone on standby when I'm a school with 100% and then after school my iPhone has about 30% - 40% battery. When I play a game, it goes from 100% to 50% within 3 minutes or so. Is this how the iPhone 5's battery supposed to be! I'm on iOS 6.1.2 do it's not even up to date like iOS 7.0.2…

  • Why does the YouTube app drain my iPhone battery quickly? When I first got the app, the battery just depleted normally for itself and it was fine. But now it's just getting worse. I even have low-power mode on, Wi-Fi, etc. And still whenever I'm watching YouTube videos, the battery just drains really quick. Has anyone else had this problem? Could it be something else, or does the sound normally take a lot of battery? Is there anything I can do with my phone so that the battery lasts longer? By the way, I have an iPhone 6s.

  • Why does my iPhone battery drain so quickly? I have had an iPhone 4s for almost 2 years. The phone has slowed down a lot since that time and the battery is drained extremely quikly, even when I'm not doing anything. If I just listen to music for 40 mins, doing nothing else, with a locked screen, my battery will go down 20%. It's insane. I never overcharge my phone. I charge it to 100% before I go to sleep and when I wake up its around 96% @ WB, No, even with everything closed it, the battery still leaks.
