How do I reset Battery usage not showing?

Ever since I jailbroke my iPad mini 3 and iPhone 6 Plus, both on 10.2, my battery usage does not appear anymore. Is there something I can reset using iFile ? I tried resetting all settings. That did not do anything. I went to Var/mobile/library/preferences and deleted batterycenter.widget.plist and that didn’t change anything either. What else can I try?
