My iPhone 4 dies really fast?

So I have an iPhone 4 and once it's completely charge after only like 20 minutes its dead again. It does this even when I'm not on my phone. Also if i let it die, it takes forever to turn back on. Last week it took a day to turn back on! An I already have all my apps closed, brightness down, locked. All that stuff.

Do I need to get my battery replaced? Where can I go and how much will it cost if I do?

Please answer!

Charge it for a day

go to the apple store

If you didn't charge it to 100% the first time, the battery is often bad. But even if you did, it seems to be something wrong with the battery, and i would probably buy a new one…

Yah it looks like you need to change your battery and try to call the Apple Store explain it to them about it ( thats only if you have warranty in it) if you don't you are screwed. And i don't know how much it cost

There's obviously something wrong with your phone. You might want to try looking in best buy to see what wrong or go to an apple store. It might be more expensive then replacing it yourself but atleast them you know it's done right

  • My iPhone 5 dies extremely fast? I have an iPhone 5 that I pretty much only use while it's connected to the charger it dies anywhere from 90-100% it barely goes lower than that before it dies. I can usually wait a couple minutes and turn it on again but then it dies even quicker than before. Anyone know the problem? Do I need to replace the battery or what? And how much does it cost to get a new battery? Thanks. Oh and it's blacklisted I don't know if that makes a difference
  • My iPhone 4s Dies That Fast? So I was snowboarding with phone listening to music and I really really got cold and i used it and it died at like 46% now like a day later. My phone goes down at least a percent a minute. I want send it in buy I have an app that has almost 500 songs that I downloaded. And I'm afraid ill lose all my apps + all the music. Is there a way I can fix it my self or what should I do?
