Documents and Sync using up all my data

This will fix the issue temporarily, but isn't a good method if you want to use the benefits of having iCloud. You should go into your settings for cellular data usage, Settings>Cellular>Scroll to bottom and make sure iCloud Drive is not enabled.

As mentioned, logging out of iCloud and back in can sometimes resolve many issues with the syncing of your account as well.

Hey! I had this issue. Very bad. 70 gb in less than 3 weeks. Easy fix, I know it may suck signing out of your apple ID but I signed out so my icloud isn’t signed in. Go to settings and right at the top, hit your name or apple ID and log out! I had a major problem where my data was super high on documents and sync and a very high battery usage causing my battery to die super quick! I know this isn’t the best fix but I finally found out after dealing with apple and trying to figure it out. Icloud will constantly sync with documents and data which causes the documents and sync which then causes the high data usage. Ever since logging out so my phone doesn’t use icloud, I have not used any data for 6 hours on documents and sync.

Hey, one more addition to that reply. When you go into your app store and update your apps, just sign in there. When I did that it kept me signed out of icloud, so you can still download apps with no problem at all. Just another heads up

Hey mvan231,

I actually did turn off icloud drive in cellular data, and it didn’t make a difference at all. Its the phone that’s syncing with icloud, and staying in a constant state of syncing. Even with icloud drive off in the data section, my data still skyrocketed on ‘Documents and sync’

After two months of this constant high data usage, of using 100+ GB this month with my phone doing documents and sync. This was the thing I found to work and actually not sync like it was. In my settings it says that icloud is off. I can’t tell you how much of a big difference I see on battery usage and on my data usage. My phone used to die at work if I left my data on... now my phone won’t even die 1% when I’m working an 8 hour day and my data stays on.

This would make a difference for people who never want to use icloud, and I partially understand due to the low storage.

Just downloading like lets say instagram or any app, it would start right back up on that data usage. It was definitely odd. One thing I noticed before was when going into reset and acting like I was going to reset my phone, it would pop up with a message saying that documents and data would need to finish syncing with icloud, just a message that wouldn’t go away.

That is a lot of data usage. I can certainly see how that would cause massive battery drain and frustration.

You shouldn't have to completely log out of icloud for this to be fixed though. Have you tried to reset your settings and see if it is fixed?

I’ve tried resetting my phone from new, twice. Had the same exact issue. It started to fix itself after I got the new ios update but then after downloading a single app, it started to sync again. The app was one I used on my last phone that never have the data issue.

If you don’t install that app, does it work fine? It seems strange that even setup as new that you’re having an issue after installing that app.

Which app is it?
