So now that you know your iPhone's battery is mortal, practically degrading bit by bit each time you recharge, wouldn't you want to know how to extend your battery life? There are steps you can take so that you don't have to recharge as often, as to extend your the overall lifespan of your battery before it has to be replaced:

1. Update to the latest software. The update may contain ways for your iPhone to use less energy.
2. Use your iPhone so that you charge it at least once a month. It keeps the electrons flowing in the battery.
3. Lock your screen when you're not using your iPhone. This would prevent it from turning on everytime you touch the screen, saving battery power.
4. Turn off your WiFi and Bluetooth if you're not using it.
5. Turn on your Auto-Brightness. This saves your battery the extra energy if you don't need that much light to see the screen.
6. Turn off your equalizer when you're playing music. It might not seem like much, but your iPhone still needs extra energy to process it.

If you want to be really extra careful about your iPhone, you can also make sure you only operate it in 32 to 95 degree Fahrenheit environments. That's when they work best. Room temperature is, of course, well within that so relax. Just don't put it in the oven.
