The iPhone 5 doesn’t exactly have the best battery life. Using it more than a little bit for Facebook, texting or calling will quickly run right through that battery. Luckily, there are ways to preserve that a bit. One such way is to turn off location services.
Our friends at CultofMac have a useful way of giving your iPhone just a little more battery life. You will have to go to Settings>Privacy. From there, you can switch Location Services off with the toggle, or you can turn off location services for individual apps (better for privacy if you only want to block out certain apps.)
It’s a simple function, but it can make a world of difference when battery is important.
