No matter what your iphone features are, you can easily extend the battery life for your iPhone.
You can extend the battery life of your iPhone by shutting off Wi-Fi. If left on, the iPhone will constantly scan for nearby Wi-Fi networks. This will rob your iPhone of it's precious daily and overall battery life.
In the first step Go to Settings from your iPhone's home page.
In the second step, while in Settings section please select Wi-Fi
In the third and final step, while in the Wi-Fi section please turn off Wi-Fi by flipping the virtual lever to the off position. This will save the battery life of your iPhone. Try this for a couple days and you will definitely notice a huge difference in battery life. You will not have to charge the iPhone as much. I do this all the time and only have to charge my phone at the end of the day.
