The Ultimate Guide to Saving your iPhones Battery Life

If you have a smartphone, then you have undoubtedly had the experience of your phone needing juice while on the go. Scotty Loveless, a former Apple Store Genius Bar employee, has had the same experience and made it his mission to find out why this happens and what to do about it with a post on his blog Overthought.com.

Here are his steps to saving your battery life:
Step 1: Disable Location and Background App Refresh for Facebook

Head over to Settings > General > Background app refresh and turn off Facebook.  Disabling this will save your battery.
Step 2: Disable Background App Refresh for Apps You Don’t Care About

Same steps as Facebook above. Go to Settings > General > Background Refresh and turn off the apps you don’t care about.
Step 3: Stop Quitting Your Apps in Multitasking
Step 4: Disable Push Email Temporarily
Step 5: Disable Push Notifications for Apps That Annoy You
Step 6: Turn Off Battery Percentage

You can find this setting in Settings > General > Usage, right above where your battery times are listed.
Step 7: Go to an Apple Retail Store
Step 8: Enable Airplane Mode in Areas of Poor Cellular Service

One major reason your battery could be draining too quickly is poor cellular service. When the iPhone detects that you are in a place of low signal, it will increase the power to the antenna in order to stay connected enough to receive calls (primarily) and maintain a data connection.

This will destroy your battery life if you are constantly in a location with 1 bar or no service at all. The unfortunate thing is that this can happen in more places than you expect — any building with metal studs in the walls, aluminum buildings, buildings with dense concrete walls, heavily populated city areas, and downtown areas with with lots of tall buildings.

From the post:

I made it my mission to discover the specific reasons for iOS battery drainage. This article is a product of my years of research and anecdotal evidence I gathered in the hundreds of Genius Bar appointments I took during my time as a Genius and iOS technician, as well as testing on my personal devices and the devices of my friends.
