Calendar app in iPhone use relatively huge amount of cellular data

I'm using a 500MB plan, so my cellular data is very limited. Each month I will check which app on my iPhone used most of the cellular usage, and the built-in Calendar always used the highest amount of cellular data.
I already set the Calendar to sync to "Events 2 Weeks Back" only, and I installed Sunrise calendar and only use it to create new task, edit task, etc. So far Sunrise calendar is the only calendar app that directly access my iCloud calendar. So I can make a comparsion between the two.
I reset the cellular statistics a week ago. Today, the usage of Calendar and Sunrise are as follows:
Calendar: 23.9 MB
Sunrise: 581 KB
They are displaying the same amount of information, the only difference I think is Calendar use Push to keep updating itself, so it consumes this relatively huge amount of data. (>90MB each month!)
I tried disable the cellular usage of Calendar in the past, but then I cannot see the most up-to-date information in the Notification Center. So at last I have to re-enable it again.
Does anyone have similar problem? Is there any solution? Thank you!!!

Hi Robert,
Thank you for the comments but I somehow think we are miscommunicating.
1) I have no problem backing up the phone locally (or to icloud if I wanted to)
2) I have no problem turning on or off cellular data usage for any app on the phone
3) I have no problem seeing what apps are enabled or how much cellular data they use
My problem is the following
APPLE's Notes app used 2.7 GIGABYTES of cellular data (before I disabled cellular data for this app) despite the fact I wasn't even using the app. I didn't change any setting for Notes, I didn't do anything with it except create one note on October 15. It would seem to me that this excessive usage is a bug or oversight in Apple's design of the app.
The purpose of this post is to warn others of the potential issue and to see if this issue has been observed by anyone else and if there are any actual fixes. Disabling cellular data for the app is a work-around ... but will the problem begin again if cellular data is re-enabled?
Your suggestion of erasing all content and settings and then restoring the phone from the backup sounds extreme but would it solve the specific problem of excessive cellular data usage and if so .. why?

In repeating events , in the calendar app of Iphone or Ipad,

In repeating events , in the calendar app of Iphone or Ipad, How can I stipulate for egsample: "every second tuesday of the month " or even every last monday of every second month..
These selections work in the Google Calendar. but I cannot find the way to do it in the standard ipad or iphone calendar
all I can find to select are "Monthly , weekly , . I want to be able to select "day of the week " or "day of the month" Thanks ,
Victor

The iPhone/iPad version of iCal doesn't have this option, but the Mac desktop version does (assuming you use a Mac). Follow the directions below and then sync your device with your Mac and the repeating event will appear in your mobile device.
Open iCal on the desktop. Make a new event. Double click on the event and then click "edit." Change the repeat option to "Custom..." Select frequency as "monthly." Click the bottom radio button that says "on the" to enable you to set which day to repeat on. Close the event info window and then sync your device.
I hope they enable this option in the mobile software soon. It is a glaring omission for a calendar program.
P.S., sorry, I just noticed you didn't include a Mac in your hardware list. I don't know how you'd accomplish this with Windows. Maybe this post will help someone else, though.

I'm having difficulty downloading apps to Iphone using my PC. I keep reading that there is a "device" button located in the Itunes page... but I don't see it.

What do you mean?
You buy an app from itunes on your computer?
If so, then sync it to your iphone.
Open itunes, connect iphone, select the apps you want under the apps tab and sync.

Updating iphone4 apps from iphone using Wi-Fi

I could not seem to get my iphone4 to update any apps from iphone using Wi-Fi. It simply goes into the menu and no update shows up.

I fixed the problem by following instructions on http://appletoolbox.com/2012/10/app-store-not-working-blank-screen/
I have copied the instructions below for convenience:
Several users have reported an inability to access the App Store, meaning that when the buttons Purchased, Search, Categories, or Charts are tapped, users are shown blank pages and nothing loads when they want to use the App Store on an iPad or iPhone. Several people also reported that this problem started after they updated to iOS 6.
How to Fix
Please try each step until you resolve your issue:
Tap Settings > General > Date and Time > Set Automatically > Off. Set the date one year ahead. Then try to access the App Store.
It may be a connection issue. Try changing your DNS settings to Google’s open DNS by tapping Settings > Wi-Fi >, tap the blue arrow next to your current Wi-Fi network, and then tap the “DNS” field and enter the DNS servers; 8.8.8.8 (Google’s Public DNS). (see this article)
Close the App Store completely by pressing the home button twice, pressing and hold the App Store icon until it starts to wiggle, then tapping the minus sign to close it. Re-launch the App Store.
Restart your device by pressing and holding the sleep/wake button until “Slide to Power off” appears.
Launch the App Store; if it is still blank with nothing shown, wait a few minutes. Sometimes apps may load slowly because of networking issues.
If still nothing appears, try changing the device’s language by tapping Settings > General > International > Language. Pick a language. Pick any other second language you already know or be familiar with. If you don’t, do not forget to navigate back in a different language. Change the language, launch the App Store, then change the language back to what it was originally.
Sign out of your Apple ID by tapping Settings > iTunes & App Store, tap your Apple ID and select “Sign Out”. Wait one minute and sign back in by reentering your Apple ID and password.

First, try a reset: hold down the home button along with the power button until you see the Apple, then let go.

Definitely sounds like an issue with your Wi-Fi network. Do any other devices on the network have similar issues? Is it an issue only with downloading apps? You can check by trying to load a website in Safari.
I would try turning your Wi-Fi router off for 1 minute, and back on again.
After doing that, disconnect and re-join the Wi-Fi network on your iPhone and try downloading an app again.

My problem - when syncing and error messages comes up: iTunes could not sync calendars to the iPhone because an error occurred while margin data." I've tried turning the phone off and back on, & tried both USB ports but get the same thing. What can I do next since it doesn't give me even one clue as to what the error would be?

Before I started to resync calendars one by one as suggested in the troubleshooting article, I remembered something that came up in a sync when I first attempted : a 'which one do you want to keep' message about a repeating calendar event, which came up with three options, one from Calendar, and two from iCal on the phone. I deleted that event, then went through the calendar resync one by one, and all seems OK now.
In Music there is a way to find 'ghost' items that show up as grayed-out on the menus, so that you can try to reassociate or delete them. It would be nice to have a similar way to work with Calendar!
Thanks for pointing me to the right article.

When syncing my iphone i get a msg, "itunes could not sync calendars to the iphone because an error occurred while merging data" I sync my calendar to outlook. My iphone calendar has all and the most updated information. Outlook shows only recurringMY

I'm at a loss as to what to do. Any help is appreciated. When syncing my iphone I get an message, "itunes could not sync calendars to the iphone because an error ocurred while merging data" I sync my calendar to outlook. My iphone calendar has all and the most updated information. Outlook calendar only shows my recurring events.

hi there,
i've found a great & simple solution for this problem
just open your iCloud acc on iPhone
turn off calendars (it wil ask you to keep info or not - KEEP IT!)
and turn back on (MERGE!)
now SYNC it..
and that's it
PS in my case it was contacts so the procedure is the same..

I m having problems with both my iphone 3gs and 4 when my cellular data is on and my battery is fully charge but out of suddenn it will shut off can i know how can i troubleshoot this issue thanks

simply try doing a back up and restore
when going thru the activation screen, select SET UP AS NEW and then test your device. if it is not shutting down then it could be 1 or more apps tht have been downloaded wch could be affecting the device
you will then need to follow the process of eleimnation, meaning add 2 apps and then monitor your phone, if nothing happes then add another couple of them and then check
good luck !!

What is a great calendar app? Currently using iPad standard app but doesn't show times

I am looking for a calendar app that links to outlook exchange on my iPad. I am using the current standard app on the iPad and it doesn't show the times. Any suggestions?

Howdy squeakyred2,
If I understand correctly you are getting the alerts from the events that you are creating on your Calendar app, but they do not show in the app once they are created. It seems to me that the calendar you are adding them to may not be checked, thereby making it hidden. To check this, first open the Calendars app and tap Calendars at the bottom:
Calendar at a glance - iPhone
Then verify the calendars you have showing. It should look similar to this:
Use multiple calendars - iPhone
Thank you for using Apple Support Communities.
All the very best,
Sterling

How can I sync my iPhone calendar with another iPhone using iCloud?

Must each iOS device being sync'd with another use the same apple id to sync using iCloud?

Yes. Both devices would have to use the same Apple ID under Settings > iCloud, and have Calendars turned on.
However, you can use another service (I use Gmail) to sync a shared calendar without having to use the same Apple ID.
My partner and I share a joint Gmail account, and have it added to our iPhones, and have the Calendar option enabled. Whenever I want to add an event to the calendar, I just temporarily change from my default (iCloud Home) to the Gmail.

IPhone using extremely high amounts of data when not in use

I have a 4S on AT&T and am grandfathered in w/ the unlimited data plan. Last month I got the notification that I was in the top 5% of data users (which sounds crazy to me considering what some other people I've read about seem to use). According to AT&T's site I had used 2.09 GB with 16 days left in my billing cycle.
Once I got that notification I logged on to see if I could find out when I was using such large amounts of data. It turns out between midnight and 1 am almost every night there was large amounts of data sent. I think this is strange since for two reasons, 1) I'm on WiFi at home in my apartment and 2) I wasn't even awake at the times these charges occurred.
Example: January 6, 2012 at 12:40 am I was charged for 417,327kb, roughly 417MB.
Similar data usage occurred almost every night going back to 12/28/11. On 12/29 I was charged for 468MB at 12:21am. Very unlikely this was actually data I used since I had work the next day and wasn't awake. It honestly looks like 80-85% of my data usage is coming from these occurrences. It also isn't likely that this is a total of data used throughout the day as there are other entries of smaller amounts spread out throughout the day.
Now, if I was on a truly unlimited plan and there was no such thing as throttling I really wouldn't care about this. But the fact is that my 3G speeds are being throttled (just ran speed test at a location I used to get over 1Mbps and I am was at .07 Mbps). I have spoken to AT&T and they insisted it was an issue w/ my phone, either the hardware or the OS. So I went to apple and the "Genius" did a DFU restore for me in store and told me that would fix it. It hasn't and now I'm stuck with this constantly happening and unbearably slow 3G data speeds for the rest of the month.
That was my last billing cycle where I was throttled down to download speeds of .07mbps. Unusable. This month I decided to closely monitor my data usage. I turned off iCloud and photostream, and turn off data whenever I'm using wifi. I turned off the sending info to apple setting.
I checked my account on ATT.com today and noticed that yesterday morning at 7:58 am while driving to work I somehow used 247 MB. Don't ask me how, I'm not steaming anything and my phone is either locked or playing music from the iPod app. I could probably stream Netflix for 5 hours and not use that much data.
I called AT&T to let them know (AGAIN) and got bumped up to a "Data manager" who was incredibly b*tchy and rude. She said there must be some app that's using that much data to update. I don't have any apps that are even that size so I don't see how this could possibly be the case. I tried to talk with her about how that can't really be the case and she just kept repeating that there must be some app using the data blah blah. I've gone to apple with this last month after failing with AT&T and at first they did a DFU restore and we restored the phone as new, then it kept happening so I went back they replaced my phone. AT&T said it must be a hardware or software issue last month, but this month it must be an app that's doing this. I can't get a straight answer from them and they just keep passing the ball to say it's Apple's problem.
I really don't know what to do. I'm grandfathered in on the unlimited plan and don't really want to change that. Say I change my plan to the 3GB's at the same $30/month. What's to say this won't keep happening and I'll be over that 3GB's in 10 days then get charged an extra $10 for each additional GB?!
I can't think of any apps I've downloaded in the past few months that would result in this change and I can't live with another 2/3 of my billing cycle being throttled down to unusable speeds.
Has anybody else had anything similar happen? I have no idea what to do next (and sorry for the long rant but I'm fresh off the phone with AT&T and I'm ******)

Thanks for the link. I only went through the last three pages and unfortunately it looks like there is no solution. I turn data off every night and turn it on only when I'm not in a wifi area. It seems that as soon as I turn it on, within an hour it charges me data for a backlog of whatever it didn't do when it was connected to wifi.
I think it's absolutely disgusting that AT&T can just dismiss this and act like it's the users fault. Apps and email updating in the middle of the night to the tune of 400MB? I highly doubt it and then when I called to ask them about it they try to make me sound stupid like I have an app or two open. Just really ticked me off. The worst part about it is that there doesn't appear to be anything I can do about it aside from never using my data.

Problems with the Calendar App in iPhone 4S

I'm having a problem the Calendar app with an iPhone 4S (iOS 6.1.3). I added a Google account with the company's domain (Microsoft Exchange option), but the calendar it's not available on the Calendar App list. I already tried to delete / restart / create the account, but so far I'm unable to see the Calendar in the list.
Any suggestions?

Tried any of these steps?
- Quit the App by opening multi-tasking bar, and swiping the App upward to make it disappear. (For iOS 6, holding down the icon for the App for about 3-5 seconds, and then tap the red circle with the white minus sign.)
- Relaunch the App and try again.
- Restart the device. http://support.apple.com/kb/ht1430
- Reset the device. (Same article as above.)
- Reset All Settings (Settings > General > Reset > Reset All Settings)
- Restore from backup. http://support.apple.com/kb/ht1766 (If you don't have a backup, make one now, then skip to the next step.)
- Restore as new device. http://support.apple.com/kb/HT4137 For this step, do not re-download ANYTHING, and do not sign into your Apple ID.

HT4528 Calendar app on iPhone 4S

Hi all! I seem to be having a problem with the calendar app. I set up an event but when I add a reminder for 2 days and another for 2 hours then I confirm it, it switches back . When I change it back and confirm it, it just goes back. Help! Anyone else experiencing this?!?!

It sounds like you are using iCloud to sync your calendar... it should actually show the name of the account, not simply "work" or "home".
Maybe you're not syncing your calendar with any account, which could explain why the invites are not being sent.
With my Gmail calendar, I tried the following:
I just created a test event on my device and sent an invite, it was never sent.
I created a test event via my Gmail Calendar web interface and sent an invite, it was sent.
This may be an iOS issue, it may be a Gmail/Google Calendar issue.
With my iCloud calendar, I tried the following:
I just created a test event on my device and sent an invite, it was never sent. Going back into the event does not show the invitees there.
I created a test event via my iCloud web interface and sent an invite, it was sent.
Seems there may be an issue in iOS
I'm still running iOS 5.1.1
