I just noticed that Facebook is consuming a lot of my battery! 😳😳😳Do you think it would be a good idea to uninstall it and reinstall it?No problems here with 17.7.1 - mainly the same as 17.7.
Have you checked the battery draining features/widgets/apps in the battery settings?
Maybe you can identify the culprit?
[edit] Also a reset/reboot of the phone could help by an app running wild.
