We’ve all been there. Your iPhone battery is under the fifty percent mark and you won’t be anywhere near an outlet for the next few hours. So what do you do? How can you ensure your iPhone won’t die in the meantime? Well, there are few settings you can adjust to add a few more hours to your battery life.

Most of us know that apps can drain battery and slow down your phone. But what if there was a single app that was sucking 20% of your battery, and potentially slowing its speed by 15%. For Android phone users, this looks to be the case. And unfortunately for all those social medial lovers out there, the app responsible goes by the name of Facebook.

In one of the company’s most subdued releases, Apple recently unveiled a new smart battery case for its iPhone 6 and 6s. The product promises to help extend your iPhone’s battery life, and can give you up to an additional eight hours of Internet use or 10 hours of talk time.
