My iPhone battery lasts for 1.5 hours maximum, what should I do

It is on whited00r custom 3.1.3 FW, the battery heats too much and won't last for more than 1.5 hours and it drains in stand by mode (and there's no app opened or push or notifications or BT or ShSh ) what should I do about that. Any help is really appreciated.
ThnQ all ^_^

Totally a hardware issue. I invite you to buy a new battery if you're able to get the back off that iphone.

If that doesn't help, set it up against the wall and use it for target practice with a rifle.

My best guess would be an overcharged battery. If you charge your phone every single day and keep it on a charger beyond its full power, they will begin to lose battery life. This happened to my old laptop that I kept plugged into the wall for extended periods of time… Eventually the battery had to be replaced because I couldn't even disconnect it from the wall without the laptop powering down. I would say you need a new battery… Good luck.

Get. An android lol

  • What is the maximum length for sending video from iphone to iphone? Is 30 seconds too much to send via mms on iphone? Sometimes it says the file is too large or long… I know there are a few apps that let you but do they still get the video even if they don't have the app?
  • What is the maximum decimal output of iPhone earbuds? I want to make sure I do not hurt my ears. According to some people, the max is 100 decibels from them. However, where did they get this from? Is this measurement taken from right next to it? People do not recommend more than 85 decibels because after that hearing loss is only a few hours. 85hrs over what time? Per day, per week?
  • What does maximum operating altitude mean? Because I read on apple.com that she maximum operating altitude for a MacBook Pro and iPhones, etc was 10, 000 ft. How do people still use them in planes?
  • IPhone 5 battery lasts less than an hour from a full charge? My battery life is appalling and from a full charge the phone will be dead within the hour. Even when I'm not using the phone the battery still drains around 10% every 20 minutes. I've got most things on my phone disabled to conserve power and I'm running the latest firmware. I changed the battery a week ago and it's exactly the same as it was before. I don't know what to do, has anyone got an explanation or a way to resolve the problem?
