Home & Lock Screen consuming screen time after iOS 18

I've been noticing for two days after the iOS 18 update on my iPhone 13. Home & Lock screen are consuming huge amounts of screen time and thus battery. These time intervals are where the phone wasn't in use, kept aside in airplane mode/DND. I have no widgets on home/lock screen. No live wallpapers, just solid black empty screens.

Mention worthy points:

I have extensive use of Face ID for app lock but those are outside of the usage time frame.
These intervals are somewhat particular to where I check time on my phone during night but I remember keeping it aside locking it afterwards.
I keep low power mode on 24/7 (that also limits screen on time to 30 seconds and disable background refresh)

I figured it out. For me at least it was the new Mirror my iPhone feature introduced with MacOS Sequoia and ios18. I have an M2 Macbook Air that I only restart once a week and it appears that even when it was in standby mode it would maintain a connection to my phone thus consistently running in the background and draining my battery, even at night in battery saver mode. This seems like a major bug as when I disconnect my phone it should be disconnected.

I removed my mac from my phone by going to Settings > General > AirPlay & Continuity > iPhone Mirroring to effectively disable Mirror my iPhone and battery drain was reduced significantly. I will be keeping this feature off until Apple acknowledges the bug and notifies us that it is fixed in a subsequent update.

Only getting worse. I’ve tried everything. I’m at my wits end. 18.01 fixed nothing.

I also thought it could be that. So, by disabling the feature, have you noticed significant improvements?

Yes, it reduced overnight battery drain by half. Idle battery drain is still there (could be any number of things) but it was much less and no longer said “Home and Lock Screen” were draining it.

I tried that too. However, the problem persists. Home & Lock Screen App keeps draining the battery.

Same here. Wait for iOS 8.1

The same happens to me, once I updated to ios18 my battery percentage is reduced to 94% to 98%

Did anyone manage to solve the problem of abnormal battery consumption in the background of the home Lock screen on iOS 18?

Oct 25, 2024 5:06 AM in response to Aahan13

Same exact problem here after the upgrade to iOS 18 on iPhone 15 Pro.

Did they tell you if it's solvable with iOS 18.1?

Oct 25, 2024 10:45 AM in response to Moskino86

I tried the iOS 18.1 (through the public “B” myself) to see if it would help and unfortunately it did not fix anything. I went Apple Store after trying that unsuccessfully.

Now I'm waiting for next week, let's hope well, I don't feel like setting everything up from a new iPhone.

Oct 30, 2024 5:10 AM in response to PhilliePharmer

iOS 18.1 doesn't seem to solve the problem. Do you have any news? Did you solve it by going to the Apple Store?

Nov 1, 2024 3:39 AM in response to Aahan13

Same problem here. iPhone 15 Pro max. Happened with 18.0 and now 18.1.

Nov 7, 2024 6:00 AM in response to BokOpStok

Too bad that as far as I'm concerned that setting in mine has always been disabled, and the battery consumption continues anyway. We are waiting for iOS 18.2.

Nov 7, 2024 6:04 AM in response to Aahan13

The battery life on my 15 Pro increased drastically after the 18.1 update.
