Cookies are the essential part of every browser and, without them, some sites won’t function as intended. On the other hand, without cookies, the sites you’re visiting are unable to track you and therefore, your sensitive data is protected or even interfere with the other sites. Essentially, you need to clear the cookies from time to time. However, that seems to be a problem with certain iPhone 6 users.

Namely, some of the users reported issues with the Safari browser closely related to cookies, especially after 10.3. iOS update. To be more precise, some of them were not able to delete the certain cookies. It seems that the particular cookies are persistent to remain within the Safari browser and they somehow override the deletion standing firm on 0 KB of space.

The ones with the latest version can only wait for next update to address this issue, while others can try out some of the presented workarounds. Hopefully, you can use them to clean all cookies from the app and continue with browsing.

How to get rid of cookies on iPhone 6

Delete cookies from Advanced tab

Even though there’s a probability that the cookies from some sites won’t get cleaned, there’s a chance that those will be or which aren’t exactly dangerous. Hopefully, you’ll get rid of some cookies if not all of them. Follow this procedure to clear the browsing data.

  1. Close Safari completely.
  2. Open Settings.
  3. Tap Safari.
  4. Tap Clear History and Website Data.
  5. Now, get back to Safari and open Advanced.
  6. Tap Website Data.
  7. Select Remove All Website Data.

Additionally, you can select the Edit within the Website Data, and clear the relentless cookies individually.

Update Safari app

Furthermore, you should try and update the Safari app. We can’t be sure is it a bug or a temporary issue, but the latest version may as well resolve your problem instantly. If your auto-update feature isn’t enabled, you can look up for the update manually on the Apple Store in a few easy steps.

  1. Open Apple Store app on your iPhone 6.
  2. Tap Updates.
  3. Tap on Safari if available to update it.
  4. Close the App and try deleting the cookies.

If the problem is persistent, move on to the next steps.

Force restart your iPhone

If the problem is more of an overall issue rather than just the native browser bug, you can try and force restart your iPhone 6 to clear all the conflicts between the app and system. That’s easy to do by following these steps:

  1. Press and hold the Home Button.
  2. While holding the Home Button, press and hold the Sleep button.
  3. Hold for the approximately 15 seconds and the device should restart.
  4. The Apple logo should appear.
  5. Now, navigate to the Settings > Safari > Advanced > Website Data.
  6.  Tap Remove All Website Data.

If those pesky cookies are still there, you should move to the next solution on the list.

Update iOS

For the time being, this problem mostly occurs with users that updated to iOS 10.3. Without a doubt, this specific version has some issues and we hope that some of the next versions will resolve this issue. We can expect the next patch (10.3.2) in the upcoming weeks since it’s still in the Beta phase. But, since we aren’t aware of the exact release date, you can from time to time check for the updates. To do so, follow the instructions:

  1. Tap Settings.
  2. Open General.
  3. Tap Software Update.
  4. If there’s an upgrade available, tap Download & Install.

Reset All Settings

Additionally, you may try and reset all settings. Have in mind that this will delete your current setup, preferences and network settings, so make sure to back it up timely before you perform the reset.

Follow these steps to perform the reset of all settings:

  1. Tap Settings.
  2. Open General.
  3. Tap Reset.
  4. Tap Reset All Settings.
  5. Enter your passcode and Apple ID.
  6. The phone will restart and you’re good to go.

However, if even this measure was of little or no avail, you may as well perform the factory reset. We’re aware that this is the last resort but sometimes is hard to overcome issues without the clean start.

That should do it. We certainly hope that these workarounds point you in the right direction. Additionally, don’t forget to share your experience or an alternative workaround in the comments below.


  1. This is a new Bug that apple has yet to admit to. You can do everything in their trite and unhelpful responses, and it won’t solve the problem. The only thing that gets rid of them – temporarily – is a factory reset of of your phone. However, they’ll come back.

    The symptom is that when you go to the Advanced tab in Safari’s Settings, and do “Show All”, then tell Safari to “Delete All”, the screen appears to show them deleted. Now navigate back one screen and re-select “Advanced”: You’ll find some 0k cookies and some 64K cookies. Now try left-wipe deleting them … the one’s that are greater than 0K will often delete, but the 0K one’s mostly won’t.

    In the end, you’ll have a collection of 0K cookies that refuse to delete.

    Not even telling the phone to delete all content, will fix this.

    Basically, Apple screwed-up Safari/Safari settings/content management in 9.1 and has yet to fix it.

  2. I have a iPhone 5s with 10.3.1. I have website data that won’t erase in advanced setting, forced reboot (holding both buttons for 15 seconds), reset network setting, have tried doing so several times, and have tried tried doing so in different orders, and I still hace data that won’t go away. I assumed it was only the porn sites I visited but i have data from the company (Johnson and Johnson) and other legitimate copyright businesses. Apple didn’t know techs couldn’t figure it out either. They recommended erase and restore all setting.
    FYI, I am also having issues with Same pictures come up under search video option. Ex, search for asian girl and while the first 10 results pictures are the same. It’s when you do another search and change time time or duration. The next 10 results will have the Same pictures as before. I have my modem signal pushed thru in the event my DNS has been hacked but that didn’t work either.
    Dreading having to delete all content and erase data, but I’m out of options. Sucks…

    • As Mark mentioned in the comment above, there’s a bug regarding the latest iOS release. As we see it, you only have 2 options: to either delete everything and start from the scratch or wait for the update where they, allegedly, will offer a solution for this inconvenience.

      • Wow…the same old generic solution. The only reason you posted this was for easy hits on a hot topic. I’m surprised you didn’t title the article, “TOP 10 THINGS AN IOS USER MUST KNOW TO SAVE THEM FROM 0KB COOKIES! L@@K APPLE SUGGESTION OF THE YEAR!”

  3. None of the above works, why would you even post such nonsense. Safari has a major bug on 10.3.1. The only fix for now is reseting your entire device.

    • This article was intended to address the issue on some of the previous iOS versions, also. But, you’re right, it seems that the ones with the latest iOS version can only wait for the fix or restore factory settings due to a bug. Thank you for your suggestion, we’re going to adapt the article as soon as possible.
