Reminders app hogging memory

Noticed recently that my Reminders app on my iPhone is consuming 7.4GB of memory and I only have few lists there and one daily reminder. I'm syncing the same on my iPad and there the same reminders take only few kbs. I've tried to clear all data and re-install the app but the same memory consumption remains. Any hints how to resolve?

iPhone XS, iOS 15

I finally solved this! my phone and iPad both had over 14 GB being used. The problem was traced to the Reminders in my library on my mac. I had once attached a picture with a reminder of my eyedrops. Somehow it kept replicating itself until there were hundreds (700 +) copies of the attachment at about 16 mb each. Deleted them disconnected from icloud. Deleted reminders app from Phone and ipad. Shut down all devices. Waited 10 minutes and fixed! From this webpage https://appletoolbox.com/fix-apple-watch-says-storage-is-full-but-its-not/


  1. On your Mac, open the Reminders App database. It should be located under Mac\UserName\Library folder\Reminders.

Hey,


I have same issue. I think it was happened after last update (15.0.2) or maybe right after update ios15. I’m not sure.


Anyway, iPhone (7) Storage shows me reminders - data and documents (5.55 GB). The total occupied storage of the iPhone is 22 GB, but after connecting the iPhone to the Mac, it shows 24.5 GB


iPad Pro - reminders 4.05 GB

Apple Watch Series 3 - reminders - 3.99 GB


I deleted everything in reminders app…

I've already canceled sync of reminders with the cloud and deleted all reminders data (it was around 3.7 GB)…

I have already tried reset my phone and then restore from backup… but nothing worked

I also checked icloud on web and reminders doesn’t work there (Perhaps it is because of unsychronization, don’t know)


Do you have some tips how figure out this issue? It is really annoying and main problem is my watch… I can’t use it properly

because of full storage

Seems no solution yet. Local Apple Senior Advisor voted this issue, was also known by Apple, all logs etc was uploaded. Definitely frustrating. Meanwhile loaded all calendars, reminders, icloud drive and others data from privacy.apple.com but there is no such gigabytes or items to find. Have been transferring all data from icloud to others like onedrive etc as this kinda behaviour and feedback times ruined my trust to this ecosystem. Only health data with watch keep me using whole icloud and apples for the moment.

Same issue. 9gb of space taken. Just switched phones a week ago from an iPhone 12 pro to a iPhone 13 pro. Erased the reminders app and stopped backing up reminders to the cloud. Two days later the reminder app showed up in my iPhone storage taking up 9gb again. Don’t understand how it just magically appeared after removing everything from my old phone.

I have the same problem. Backed up to the cloud last night and now it is saying that Reminders are taking up 10.39 GB. I have deleted Reminders from my phone, but it is still showing up. I my cloud, it has 4 lists with no actual reminders on them. I cannot currently back up my phone because it is saying I do not have enough storage.

Yeap. It is very strange. Though, it seems not to be only a problem of the reported memory. In the case of my Apple Watch 5, it appeared a message that it was running out of memory even after applying the solution proposed by Macnag. In the case of the iPhone it was using 16,55gb (see the pictures) before the solution proposed by Macnag, now it said that it is using 25,92 Gb 😩


Tomorrow (weekday) I'll contact Apple support again.
