How to take care of my iphone battery?

So I've just bought a new iphone and I want to make sure I take good care of the battery so it will last for a long time. What do I do? For some reason on my old ipod it dies really fast even with the brightness all the way down, Wi-Fi off, etc. I don't want this to happen to my iphone.

Here are some simple ways through which you can enhance your iPhone battery's lifespan:

Reduce your screen brightness

Update your iPhone's software frequently as new features will minimize your battery consumption

Turn off push notifications, fetch mail less frequently

Turn off Wi-Fi, Bluetooth and Location Services when not in use

Close out running apps

Hope it helps. If you need to secure your iphone from external damages, make use of iphone gears.
