— Robb Lewis (@rmlewisuk) January 10, 2017 David Marcus, the VP of messaging products at the social network, confirmed on Twitter that this problem had arisen due to a bug, and that it should now be solved. “Issue was isolated and fixed server side,” he wrote on Tuesday. “If you restart Messenger the problem should be gone now. Very sorry.” Though Marcus refused to divulge how many Facebook or Messenger App users were affected by this strange battery draining bug, only Android smartphone users seemed to effected by the bug. Marcus also refused to divulge details of the bug or how it was identified and fixed. One Reddit user said he even deleted the Facebook and Messenger apps as a result: “It was draining my battery really bad and smartphone was getting hot. Had to delete them.”

If that doesn’t solve the problem, delete both the Apps and reinstall them again.
