Is your iPhone 4 or iPhone 4S struggling to last a whole day without being recharged?

Fortunately, there is a simple trick to saving your battery.

The iPhone OS has the big advantage of offering multitasking which allows you to easily switch from one application to another without closing them.

Unfortunately, battery level, it is felt and it is sometimes even worse than the iPhone 3G or 3GS. Why ?

Because even if you don't use the app, it is not really closed and continues to consume battery ...

The more applications you open, the more the autonomy decreases.

How to properly close the Apps?

1. To properly close already open apps and save battery life, double-click the Home button to bring up all your open apps that are consuming power without you knowing it.

2. Then, you just have to let press on one of them to display the "Delete" button and close them one by one.

And there you have it, you have closed all the applications on your iPhone :-)

It is your battery that will appreciate.

Savings made
