Numerous users have voiced their concern that the Calendar app is hogging an astronomical amount of battery from their devices. Users have reported that if they check the Battery stats for the past 24 hours, then the Calendar app is sitting right there at the top, running for over 15 hours in the background and around 83 hours in the last 7 days.
Correspondingly, it seems to hog around 40% of the battery which is definitely not what one would expect from an app belonging to this domain. What makes the matter worse is the fact that Calendar isn’t even present under background app refresh, so you cannot disable its background activity as well. With that said, there does exist a nifty workaround that shall help you resolve this bug. So without further ado, let’s check it out.
Nearly all the users who were getting bugged with this issue had one thing in common- they were all using the Apple Watch. Upon further debugging the issue, it turned out the issue is the watchOS. So here’s what you need to do to rectify this bug once and for all.
That’s it. These were the steps to fix the Calendar app excessive battery drain issue on your iPhone. If you have any queries concerning the aforementioned steps, do let us know in the comments. We will get back to you with a solution at the earliest.
Turning off Live Activities under FaceID definitely worked for my 13 Pro. Before it lost 30% overnight, after turning this off only lost 1% overnight.
It’s all the Home Screen, when I look at the battery setting over 50 percent of battery usage is coming from new Home Screen. Even removed widgets, static image wallpaper and it’s still draining. I just turned off live activities and it seems better but still too soon to be definitive. Basically I’m turning off everything that I updated to IOS 16 for.
Hello everyone, same problem here with my 13 Pro Max. Doing nothing and it’s just draining the battery.
try turn off Live Activities in settings! I think this helps I tried this and the battery is normal since I turned it off.
settings > Face ID > at the bottom allow Live Activities on Lockscreen
Yes — I was able isolate culprit to Siri and Find My apps. It seem got better once I turned off “listen for Hey Siri” and “reset location and privacy settings”…. Apple under Cook has turned into MSFT of of early 2000s - boring and full of bugs… (eg Windows Me and Vista)…
PS: I have 13Pro Max
After some further testing in my case it looks like the Contacts of the Gmail account and iCloud Contacts sync are going in some strange loop, something is synced back and forth constantly. One indicator was the frequent loading circle in upper left corner while using the Contacts (Apple native app or phone).
Hey bud, after reading the comment about recovering the phone. I restored it through my MacBook and then used my iCloud backup and the battery drain issue has gone now! Still on 16.1.1 and no issues now!
Hope this helps bud.
Cautious optimism that I may have solved my problem. Here's what seems to have worked (I say seems because a couple times today I have had spikes where the phone gets warm and Home & Lock Screen use over 40% of the battery, but it eventually calms down--maybe just reindexing my 150 gigs of phone data.)
This time I took the phone into recovery mode while connected to the computer (If you can't update or restore your iPhone or iPod touch - Apple Support) and restored the software, which wipes the phone and reinstalls the system software from scratch. After this was done I restored from my last iCloud backup. I did this because I have over 100 apps on the phone, and really didn't relish resetting up my entire home screen, and re-inputting every.single.password. After that, I let it index overnight.
When I got up this morning I started working on the phone and after 10 minutes the battery still hadn't dropped even 1%, a dramatic improvement. However midway through the day I saw that suddenly the battery was dropping and the phone was getting warm again, so I turned on reduced energy mode and use the phone for a little while, then I turned off reduced energy mode and the battery seems to be holding pretty well. I'll follow up again after I know for sure.--Home & Lock Screen was using 46% of batteryWhen I got up this morning I started working on the phone and after 10 minutes the battery still hadn't dropped even one percent, I dramatic improvement.

Crazy process, and crazy that Apple expects the average user to go through these steps to fix *their* problem.
I have a brand new iPhone SE 3rd gen that had massive battery drain. For me it was also the sync of Contacts to iCloud that was the cause.
A good trick for everyone is to reset your mobile data statistics and then turn off Wi-Fi and let the phone rest for 15 minutes or so. Then check back and see which app is using the mobile data. It's a good chance that this is the app which causes the battery drain. If possible disable syncing for the app and see if the battery drain goes back to normal.
It seems to be the icloud sync with photo’s. When you pauze the sync, the excessive drain will stop 👍🏻
Yes! This is my analysis as well. Contacts/address book sync is the cause of my battery drain also. iPhone 13 Pro. As soon as I disable Contacts iCloud sync, the battery is back to normal.
Anyone who has questions about restore your iPhone can read this Restore your iPhone, iPad, or iPod to factory settings - Apple Support, I did this and the battery problem was gone.
Early indications are that disabling Contact Sync with iCloud has resolved my problem on both my phone and my watch.
Thank you for sharing this tip!!
Confirmed. All is good with contact sync disabled. Not a desired state and hopefully Apple can address this issue soon!
It may be a little early to say, but I did turn off "live activities" and its no longer hot and has been at 66% for an hour now. Otherwise it was dropping about 8%/Hr. Give that a try. I'll see what tomorrow brings. If this fixes it, I'll keep it. Otherwise in its box it goes and back to China.
Well sorry to hear that, because for MY 14 Pro Max just flipping that one slider has made all the difference. Previously I was losing about 5-8% battery per hour just sitting inactive. And the phone actually felt warm to the touch. After disabling live activities yesterday, I came off charger at around 5am this morning and 4+hrs later now at 9:20am I am at 99%. So I'm good to go...
