One of the biggest complaints I've heard about the new iOS 7 operating system is how much it eats into an iPhone's battery life. The question then becomes: how do we counteract that?

The new operating system features the ability to run extra apps in the background, which requires much more power and battery life. There are, however, ways to preserve battery life and Forbes has an outline of how to do just that.

The list is fairly self-explanatory to people already familiar with iPhones and the batteries, but users may need to pay more attention now than ever before because of the power of the new operating system.

Firstly, Forbes says you should kill apps you don't need. With iOS 7 updating more apps automatically, these likely take up plenty of battery power. Secondly, people are advised to dim the screen as the brightness can eat away the battery as well.

For people with the new iPhone or even just the regular iPhone 5, turning off Air Drop is also suggested to save your phone's juice.

Another option is to turn off Bluetooth and WiFi. Most of the time iPhones are set to search for WiFi at all times. However, if you're within WiFi range then it would be best to use it instead of using cellular data.

Lastly, according to Gizmodo, another idea is to make sure the GPS is turned off. The location services do take up a significant amount of battery power at once.
