In October 2015, the app Facebook for iOS has been updated to fix a problem with excessive battery consumption. Virtually four months later, no one else had brought up the subject. But Samuel Gibbs, from The Guardian, decided to do some tests and concluded that the app continues to consume a lot!
Using an iPhone 6s Plus for a week without the main Facebook app installed, I recorded the battery life every day at 10:30 pm, for a week, comparing it to an average daily one week ago with the app. I recharged the phone at night, unplugging it at 7:30 am and used it normally. I accessed Facebook for the same amount of time and for the same tasks, using the excellent social networking mobile site on Safari, just as I had done using the application. I also left the Facebook Messenger app installed.
The result? Gibbs ended the day (10:30 pm) with about 15% more battery life in the device. In addition, when uninstalling the Facebook app, he won back 500MB (111MB of the app plus 389MB of cache).
To further prove his theory, Gibbs asked other Facebook users to take the same test. The results were very similar, with an increase in battery life when using the uninstall app and using the social network through Safari.
Of course, the mobile Facebook site does not have the same features / navigation as the app, but it is up to you to make the decision. If you have a lot of battery problems throughout the day and use a lot of social media, it may be a good idea to do this test for a period.
