The Facebook iOS app ain't too good for your iPhone's battery life apparently.
The complaints of users have been flooding the internet since the past few days about the Facebook app on iPhones draining a huge amount of battery and data, even when you're not using it. A Reddit thread, dating about 2 months from now has been on the same issue with the application of the social network. The battery consumption hikes up to preposterous 91 percent of battery usage in a 24-hour period.
The technical details of the audio are yet to be uncovered.
But to stay on the safe side till a solution is brought, I suggest all the iPhone users to browse the social network website through your mobile web browser rather than the app.
