The short version: TikTok notifications stop working because of a mix of phone battery settings, iOS and Android permission changes, TikTok’s own server-side throttling, and (the bit nobody likes admitting) a genuine drop in your account’s engagement that quietly tells the algorithm to send you fewer alerts. Most fixes take under five minutes once you know which of the five it is.
The three different “not working” problems that get lumped together
When someone tells me their TikTok notifications have “stopped working,” they’re usually describing one of three completely different problems, and mixing them up is why so many people spend an hour toggling settings that were never the issue.
- No notifications at all, from anyone, for anything (a device or permissions problem)
- Some notifications arrive but others don’t, like comments coming through but likes not (a settings-within-the-app problem)
- Notifications used to arrive instantly and now come in hours late, or bunched together (a server-side or throttling problem, and the one people find hardest to accept)
Each one has a different fix. I’ve watched clients spend a week uninstalling and reinstalling the app when the actual issue was a single toggle buried in their phone’s battery settings, not TikTok at all.
The five real reasons this happens
1. Battery optimisation is quietly killing the app in the background
On Android especially, if TikTok isn’t on the “unrestricted” battery list, the operating system will freeze it the moment you stop looking at it, and frozen apps can’t receive push notifications. Go to Settings, then Apps, then TikTok, then Battery, and set it to “Unrestricted” or “No restrictions.” Samsung phones are the worst offenders here because they add their own layer of battery management on top of Android’s, so you sometimes need to check two separate settings menus, not one.
2. iOS Focus modes or Screen Time limits are silently overriding TikTok
If you’ve set up a Focus mode (Work, Sleep, Personal) and didn’t manually allow TikTok through it, notifications will be suppressed even though the app’s own settings say notifications are on. This is the single most common cause I see with iPhone users over 40, because Focus modes get turned on by accident through Control Center swipes.
3. In-app notification settings got reset after an update
TikTok pushes app updates roughly every two to four weeks, and I’ve seen notification preferences reset to default after a version update on at least three separate occasions with client accounts. Check Profile, then the three lines menu, then Settings and Privacy, then Notifications, and go through every category (Likes, Comments, New Followers, Live, Mentions) individually rather than assuming the master toggle covers everything.
4. You’re logged into TikTok on a second device
TikTok sometimes routes push notifications to whichever device you last had the app active on. If you tested TikTok on an old phone or a tablet six months ago and left yourself logged in, that device can be quietly “claiming” your notifications. Log out of every device except your main one.
5. Server-side throttling based on how you’re using the app
This is the one that gets skipped in most guides on this topic, and it’s the uncomfortable one. TikTok doesn’t send every user the same volume of push notifications regardless of behaviour. If your own posting and engagement have dropped, if you’re getting fewer comments and shares than you used to, the app has less reason to interrupt you with alerts because the whole point of notifications is to bring you back into a feed that’s currently rewarding you. A quiet account gets a quiet notification tray. It’s not a bug. It’s the same mechanism behind why TikTok likes sometimes disappear, both are the platform managing engagement signals rather than malfunctioning.
What happened with my own account (the 29-out-of-37 story)
I ran an experiment on one of my own TikTok accounts in late 2025 because a client insisted their notifications were “broken” and I wanted proof one way or the other. I posted a video that got 37 comments in the first three hours. I sat with my phone next to me the whole time, screen unlocked, app fully updated, battery restrictions off, Focus mode off. I received notifications for 8 of those 37 comments. Twenty-nine never showed up on the lock screen at all, even though every single one was sitting there in the app’s activity tab when I opened it.
The account had posted twice in the previous ten days after posting daily for three months straight. That drop in frequency, not any device setting, was the most obvious variable that had changed. When I went back to posting daily for two weeks, the notification delivery rate on comments went from roughly 22 percent to somewhere around 70 to 80 percent, based on rough counting rather than any official data TikTok publishes. Nobody at TikTok will confirm this mechanism publicly, but the pattern was too consistent to be coincidence.
Notification types that behave differently from the rest
Not all TikTok notifications are treated equally by the app’s own logic. Live notifications, for instance, are tied partly to your follower count and how often you go live, which is one reason people ask how many TikTok followers you need to go live in the first place, since eligibility and notification behaviour around Lives are more tightly gated than ordinary post alerts. Similarly, the “Shared With You” notifications that appear when a friend sends you a video work through a completely separate pipeline tied to your contacts and messaging permissions rather than your posting activity, which is worth understanding if you’re troubleshooting because the fix for one won’t touch the other. I’ve written a full breakdown of what “Shared With You” means on TikTok if that’s the specific notification type giving you trouble.
Step by step fix, in order
- Force close TikTok completely, then reopen it, and check that the app updated to the current version (App Store or Play Store, not sideloaded)
- Check phone-level permissions: Settings, then Notifications, then TikTok, make sure Allow Notifications is on and Lock Screen and Banners are ticked
- Check battery settings and set TikTok to unrestricted (Android) or disable Low Power Mode when you need alerts (iOS)
- Check any Focus mode or Do Not Disturb schedule and add TikTok as an allowed app
- Open TikTok’s own Settings and Privacy menu and re-toggle every notification category, even the ones that already look switched on
- Log out of TikTok on any device you’re not actively using
- Post consistently for two weeks and track whether delivery improves, the same way I did with the 37-comment test
The uncomfortable bit people skip
Most articles on this topic will tell you to check your battery settings and call it done, because that’s the fix that makes the platform sound broken rather than the account sound quiet. But if you’ve done all the technical checks and notifications are still patchy, the honest next question is whether your posting frequency and engagement have dropped, because that’s very often the actual answer, and it’s a less comfortable one to hear than “clear your cache.” I say this as someone rebuilding accounts in public after a rough few years, quiet accounts get treated quietly by every platform, not just TikTok, and Instagram does the same thing with Reels visibility, which is part of why so many people end up wanting to mute Reels on Instagram entirely rather than fight the algorithm’s assumptions about what they want to see.
How to stop this becoming a pattern
If you rely on TikTok notifications to know when to respond to comments or DMs for your business, don’t build your whole workflow around push alerts arriving reliably, because they won’t, even with every setting correct. Build a manual check into your week instead. I keep this inside a wider realistic social media schedule for busy founders, ten minutes each morning going through the activity tab directly rather than waiting for a buzz on the lock screen. It sounds basic, but it’s the only method that’s never once let a client miss a comment from a paying customer.

Frequently asked questions
Why did my TikTok notifications stop working all of a sudden?
The most common sudden cause is a phone update or app update resetting your permissions or battery settings, so check those first, but if the timing lines up with a drop in your own posting or engagement, the platform may simply be sending fewer alerts because there’s less activity to notify you about.
Do TikTok notifications get delayed on purpose?
TikTok has never officially confirmed deliberate delay based on account activity, but in real testing, notification delivery rates changed noticeably alongside changes in posting frequency, which strongly suggests some form of prioritisation is happening on their end rather than a pure technical fault.
Will logging out and back in fix TikTok notifications?
Sometimes, especially if the issue is a stuck session or you’re logged in on an old device that’s silently claiming the notifications, but it won’t fix permission or battery-related problems, so check phone settings first before resetting the login.
Why do I get comment notifications but not like notifications on TikTok?
TikTok treats notification categories separately inside its own settings menu, so a partial reset after an update can leave one category enabled and another disabled without you noticing, which is why checking each category individually rather than trusting the master toggle matters.
