I never got them to show up for my current "to-do's" but I did get it to work yesterday when a reminder went off at 5:30 and I still hadn't completed it.
It may only be for ones that have a time associated with them.
This is correct.
Pretty sure it's a bug, but this definitely annoys me too. However, I did figure out how to get the badges to show up. If the iPhone is locked when a reminder notification comes through, if you slide to view the reminder notification directly, that reminder will be reflected with a badge. If you don't slide to view the reminder OR the reminder came through while unlocked but you DISMISSED IT, then the only way to get the badge to show is to go view the reminder VIA the notification center (i.e. not by tapping the reminder icon), OR, clear the overdue reminder(s) from the notification center by tapping clear. Interestingly, if you have overdue reminders whose badges have not yet "posted" so to speak, and one comes through and you tap to view it (and only it), all of the other overdue reminders badges become visible on the app icon.
Apple needs to fix it so that as soon as a reminder notification comes in, it's badge instantly appears, just like when a text message comes in, regardless of whether or not you cleared it from the notification center.
EDIT: And yes, all this only applies to reminders that have an alert time. In the above description by "overdue" I mean the alert for the reminder has gone off. Obviously, there is no way to have reminders with no alert associated to be reflected in an icon badge, unlike most every 3rd party reminders app.
You have to set a level of priority within the reminder to something other than none. That will make the badges appear when something is due.
Wow! Is this true? I've been searching for a solution for months.
EDIT: Tried this. Didn't work. Dang!
Interesting. That's how it works for me. I never had badges (never even thought about them for reminder) then I set some reminder with a high priority and bam badge icon. So starting playing with it and if none no badge if low, med or high I get a badge. However it seems to be broken now! Perhaps iOS 6.1.2 or 6.1.3 broke it. It was working now it isn't!!! It was introduced in iOS 6 so one of the many iOS 6.x updates apparently killed it
[Edit] Set up reminder with alarm date & time
Alert goes off at specified date & time.
Unlock iPhone - Reminder badge has not updated.
Open Reminders app - reminder is displayed in list, as expected.
Close Reminders app - badge count has not updated.
However if either:
Swipe the lock-screen notification when the alert fires, or
Select the reminder from Notification Center, the Reminder app opens, the reminder is highlighted briefly in red and the date/time text turns red too. Upon closing the application, the badge app appears. Sorta broken I guess. I don't believe it was working that way before.
Great summary. I'd like to add that if you load up icloud in your computer browser and mess with the reminders app (which properly shows the badge, unlike iphone), the badge will appear on the phone (forgot what exactly you have to do in the icloud, but I think just clicking on the reminder icon will do).
Also, I'd like to raise this to Apple tech support to get the problem resolved asap. What is the most effective way to do this?
This is pretty annoying. Have had this issue for several months now and I agree as others have stated, it just doesn't work as it should. Clearly a bug.
Will submit on Apple feedback page.
Also, I have removed Reminders from notification center to see if that usage pattern at least allows the badge icon to render correctly when I have an overdue reminder, which is the most important feature to me to have working properly.
I've been searching for a solution to the 'due today' tab not showing a badge for the last 87 years. This worked. Thank you so much.importance
