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 almost 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!

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


It seems that these attachments even though deleted from mac now is still haunting iCloud and returning to iPad and iphone. I will continue on my journey and post again. Hopefully iCloud will catch on

Sounds pretty much what I did. For me it was the “infected” backups. Are those files still on the Mac? I had to wipe my pad and phone because they and all backups had those files from the Mac.


Before iOS 15 my 14 GB was in the “Other system data category” when l checked iPhone or iPad storage. When I updated to 15 they moved to reminders. Then I was able to find them on My Mac.


Since the problem seemed to be the iOS backups in iCloud and the iOS device backups on my Mac. I had turned off iPhone and iPad to keep them from backing up then deleted the iCloud backups of them. I made sure to backup the cleaned Mac reminders folder by turning iCloud off and on again although I also just switched the back up to iCloud for reminders for all devices off too.

Interesting that backups could lock the memory of ios device so that app data can not be deleted. I havent ever done ios backups to mac and I deleted all icloud backups like nearly all from cloud what one can. Also the reminders icloud data was succesfully flushed so that mac reminders wasnt populating any strange attachments and ios reminders started to work much faster (especially when turning icloud reminders off and on). Still there is no change to delete the ios device app data of reminders app. Except that factory reset all and painful create all from zero. That is not my solution as there are similar cases without ever mac owned, also in our family, so Apple has to bring a solution to this.

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.
