Getting the Most iPhone Battery Life

Apple added a feature to allow apps the ability to fetch new material in the background.

The feature called, “Background App Refresh” means that when you fire up Buzzfeed or another similar app it is already updated so you don’t have to wait for new content to load. This can be awesome because of how fast it is, but it also eats a lot of battery.

Turn off “Background App Refresh” on applications you don’t use often.

Settings > General > Background App Refresh
You can also disable the feature entirely if you don’t want any apps eating away at your battery.
