WHEN it comes to smartphones, everyone suffers from a bit of range anxiety. Not in the car sense, where you might wonder if you’re going to make it to the next petrol pump, but instead in whether you’ll make it through the day before your phone conks out.
There are all sorts of tips and tricks you can find online to try to combat battery fatigue, some more useful than others.
So one rather annoyed former Apple expert — an Apple Genius, in fact — decided to take a long hard look at what actually works to extend your battery life without removing the core functionality of your iPhone.
You could always switch off services like Wi-Fi or 3G/4G data, or not use apps — but where’s the fun in that?
What Scotty Loveless found was that the chief culprit in iPhone battery drain was, rather surprisingly, the Facebook App. In his tests, which involved running specific developer tools to track activity on an iPhone, he found that the Facebook app was continually requesting resources, and as a result hogging battery power, even when he wasn’t using it.
He wrote this finding on his blog:
“During this testing, Facebook kept jumping up on the process list even though I wasn’t using it. So I tried disabling Location Services and Background App Refresh for Facebook, and you’ll never guess what happened: my battery percentage increased. It jumped from 12% to 17%. Crazy. I’ve never seen that happen before on an iPhone.”
That doesn’t mean that you should immediately uninstall Facebook if you’re happy using it on an iPhone. Instead, the solution rests in disabling the background services that Facebook is using that hog so much power.
Specifically, Location Services (found in Settings>Privacy>Location Services) and Background App Refresh (found in Settings>General>Background App refresh) for Facebook appear to be the culprit.
Disable these, at least when you’re not using the Facebook app, and you should see a resultant uptick in your iPhone battery life.
