Hi there,
I have this thing going on: During day, my battery usage is normal and everything is nothing less than perfect. HOWEVER, during night there is some app or something which is using my battery significantly, but i don't know why. It is showing me "usage by app is not available for x:xx - y:yy". Attached a screenshot.
Any ideas? suggestions? did it happen to someone in the past?
iPhone XS, iOS 12
Good morning dor_b!
I see that you have some concerns about battery usage during a specific time at night. I'll be happy to help.
Does this happen every night? If so, are you able to tap the "Last 10 Days" to see if app activity will show for those time periods for different nights? Or does it still say that usage by app is not available?
Another setting to check is to see which apps are using Background App Refresh, as apps that have Background App Refresh toggled on can still use resources even when the iPhone is in an idle state. Learn more under "Use Background App Refresh" here: Switch apps on your iPhone, iPad, or iPod touch - Apple Support
One other thing to look into is to see if you have iCloud backups toggled on, as iCloud backups occur at night, when the iPhone is locked, connected to power and charged. Learn more here: iCloud: Back up your iOS devices to iCloud
Cheers.
