How to get your battery to last on your iphone?

I need help with my battery with my iphone it goes out so quick any help? Give me some advise please help me

You can:
-Turn down brightness
-turn off Bluetooth
-turn off Wi-Fi
-3G/data even
Brightness helps a lot and turning off Wi-Fi helps cuz it keeps your phone from continually searching for internet

Go to settings and turn off everything from Internet to location services e.g. Brightness of screen, volume, notifications and don't play games that require heavy amount of juice to function. It is recommended to let your apple device run out of battery once a month or so. There also many other factors that also takes juice such as the amount of apps you have notes etc.

I carry my charger every where. And I mean every where. The other suggestions are good. If you need to charge it faster, place it on Airplane mode also.
They have a case that is also a charger that gives you longer life but I forget the name.

  • Why doesn't the iPhone 4s battery last? This is annoying me so much. I swear I charged my battery to 70% took it out, by 1 hour of using it my battery just decreased to 35%! Why? I have to charge it every 2 hrs or just use it and keep in the charger. Has anyone experienced the same? Is there a way to increase battery life? And if this helps, my iPhone is actually jailbroken. But ever since I updated to 5.1.1 my battery has been a total nightmare.
  • Why does the last percentage of my iphone battery takes so long to charge? I have noticed that the very first percentages (1-20) of the iphone battery charges very quickly, but when it comes to the last percentage (99-100) it takes like 15 minutes to charge!
  • What can I do to get my iPhone battery to last longer? I close everything running. But if I listen to music or look at videos, it drains very fast. Like 30 minutes.
  • How to get my iPhone battery to last longer? My battery seems to die around 4 pm if I stop charging it at 7 am. (Have to go to school… ) how do I get it to last longer? Maybe to 6-7ish pm? I listen to music ALOT if that does any damage, and in school, I only get 1-2 bars.
