IPhone battery issue - exchange calendar sync the primary suspect

I previously posted about very poor battery life and how a full re-install and reset seemed to fix the issue. The battery life was great for a week or so then I tried to go from my calendar on .me to my calendar on exchange. Then the issues re-appeared.
I am 99.9% sure that calendar sync via exchange is the issue. I am not sure if it's a funky server setting that my company has or what. It seems to work fine for others in the company however my e-mail account at work is relatively old compared to theirs. I am also on a Mac using Entourage. I made sure push was turned off and only fetch every hour. Still the same issue.
Again there is no battery drain when synching via iCal/.me. This kind of defeats the purpose of push calendar for me because I need to synch Entourage with iCal then iCal with .me. This means I need to be on my company network to sync. So the only time my calendar syncs is when I have my laptop on the company network.
The reason I'm writing is in hopes that someone from apple reads this and posts a fix. The CPU gets noticeably hot when exchange calendar sync is on so I know something is up. If you have any more info on this please let me know. I am also going to try the apple store tomorrow. Maybe it's a defective phone BUT since it works for everything except Exchange cal sync I am thinking it is some server/client polling issue.

I KNOW THIS IS lONG, BUT PLEASE TAKE THE TIME TO READ IT.
OK - After about 5 hours of troubleshooting I have FIGURED out why my battery was lasting only 3.5 hours. I hope this helps.
1. completely wiped the phone away and brought it back with push disabled. EVERYTHING FINE
2. I enabled push waited 1 hour. EVERYTHING FINE
3. I enabled mail push syncing. EVERYTHING FINE
4. I enabled contacts push syncing. EVERYTHING FINE
5. I enabled calendar and BAM battery starting spinning in overdrive. The calendar was the issue.
6. I disabled push and to my surprise it did not get better, only after a reboot did the batter return to normal. OK - so I have narrowed it down to the calendar.
7. I am using Outlook 2007 with Exchange 2003.
8. I took a bold step and archived my entire calendar to a pst file so it left nothing in the calendar.
9. Again to my surprise the battery started draining immediately when i enabled the calendar again. On a hunch I checked the properties of the calendar and it said there was a few kb left. I could not do anything to find these.
10. I logged into Outlook web access (http://exchangeservername/exchange - if enabled) and did a search on the calendar and it found two orphan calendar entires. I deleted them.
11. I enabled calendar syncing again and it went perfect. I then copied back all of my calendar entires from the archive pst to the calendar and luckily no problem.
The push service must have not known how to process these two entires and was just chocking on it. For the last two weeks I have been getting 12-14 hours from a charge with 3-5 hours of use. Farb better then the 3.5 hours with no usage. I hope this helps!!

  • IPhone 2.0 exchange calendar sync issue with PUSH enabled

    I have setup Push sync over Exchange for my iPhone. If I accept an incoming meeting request it does not update Entourage calendar. If I change delivery setting to fetch, the issue disappears. Is this a known bug? BTW - several of my work colleagues have noted the same issue. All are Entourage users too.

    You can accept/decline/mark tentative any meetings sent to you, and you can also edit meetings you create (whether on the phone or in Outlook, OWA, etc).
    IMPORTANT: make sure your user name for the Exchange account as entered on your iPhone exactly matches the case of the user name set up on the Exchange server. (Settings > Mail, Contacts, Calendars > Your-Exchange-Account > Account Info). Set both the Email and Username fields to exactly match the case of your email and username on Exchange. Look up yourself in the Exchange Address Book in Outlook and see how it's entered. i.e. [email protected] must be entered in the iPhone with the same capitalization. I also edited my own contact cards to match -- just to be sure.
    Otherwise, the iPhone gets confused with meeting invites and might ask you to Accept/Maybe/Decline your own meetings! If this is the case, you also won't be able to edit meetings on the iPhone even if you create them.
    As far as i know, the above is only true for Exchange accounts. I had this problem, and solved it last night.

  • I am facing issues with my music on my iOS device. I have five devices connected to my apple id. And out of which a Windows Machine and iPhone is not able to sync the purchased songs on the the Windows machine and the iPhone.

    I am facing issues with my music on my iOS device. I have five devices connected to my apple id. And out of which a Windows Machine and iPhone is not able to sync the purchased songs on the the Windows machine and the iPhone. The iPhone4 shows the songs are not supported and on the Windows Machine the songs do not play completely. Can anyone advice what could have gone wrong ? Because rest of the devices are synced to MacBook and they are able to sync the content normally.  I have even subscribed to iTunes Match but the problem is still not fixed.

    Firstly...  a little Clarity...
    Devices refer to iDevices... iPod... iPhone... iPad. ..   Not Computers.
    Authoriation applies ONLY to Computers... of which there is a Limit of 5 per Apple ID.
    If the issue is with iTunes on your Windows Computer... Perhaps you need to Re-install iTunes...

  • Longstanding Exchange Calendar Sync Bug Persists in iOS 7 / 7.0.2

    For those who sync their iPhone / iPad / iPod touch to a Microsoft Exchange e-mail environment, you may be aware that there's a longstanding Exchange Calendar Sync bug (affecting iOS 4.x - 6.1.3).  An otherwise functional iDevice may suddenly remain warmer to the touch than normal, exhibit much shorter battery life, and start using cellular data at up to ten times the user's typical pattern.  I've taked with Apple Support several times, and was never able to get an answer.  The fix involves simply opening the Exchange account settings on the iDevice, shutting off calendar sync for thirty seconds, and turning it back on.  This is nothing new.
    Over the weekend, an executive’s iPhone 5 (on Verizon) and his iPad 2 (Wi-Fi only), both running iOS 7, began exhibiting runaway connections to my employer’s Microsoft Exchange ActiveSync server.  The user upgraded his iPhone 5 to iOS 7.0.2 over the weekend, but the problem persisted.  In one 24-hour period, his iPhone checked in with our server 45,009 times, while his iPad connected 55,547 times.  Normally we’d expect to see a single device connect a few hundred times per day rather than tens of thousands.
    I've written more about it here.

    This is still a problem in iOS 7.0.4 as well.  We just had runaway calendar sync behavior on a 4th generation iPad running iOS 7.0.4 (iPad3C4/1102.55400001), which connected 75,436 times in a single 24-hour day.

    Looking for exchange calendar sync system to replace sucky groupcal.
    I've had nothing but problems with it. I get duplicate calendars, duplicate calendar entries, and the daemon stops updating from the
    then the support folks are threatening to cut off support and no longer help me to fix their broken code!
    I wasted money and so much time on this app, is there anything else out there that does a better job?

    Not to mention that it doesn't work with Leopard now! I wish there was a way to get my Exchange calendar to sync to a third party that would sync with iCal 3.0. Since there is not support for CalDAV it would be nice if Exchange would support this!

  • Iphone changes time in calendar sync with Mac?

    Can anyone help?
    I have a 24" mac running Leopard 10.5.7 and an iPhone 3G. When I sync the two any calendar events I have on the Mac arrive on the iPhone with the time changed by 8hrs (it moves them 8 hours earlier). Does anyone know what I have to do to fix this?
    I have checked the date and time settings on both and both are correct. I have also checked the time zone settings on both and both are set to London, BST.
    Thanks

    further info...
    on synching I have also now noticed that the times on the Mac have also changed to 8 hours later (9am meetings are now at 5pm).
    What is happening?

  • Exchange Calendar Sync

    Is anyone else having problems syncing the Calendar app to an Exchange server?
    I have my work email account (Exchange) setup in Mail and calendar. Up until a few days ago everything seemed to be working fine.
    Then sometime around the latest OS update i started noticing the exclamation mark apprearing next to my exchange calendar in the calendar app. Mail continued to work normally. This exclamation mark seemed to be intermittent at first but then i noticed it wasnt pulling in new events that had been created. Clicking on the exclamation mark revealed nothing (i expected some kind of dialogue box explaining the problem).
    I decided to delete the exchange account and start from scratch. Now however, the calendar wont pull in any event data at all. Throughout this, the mail seems to have carried on working fine.
    Any advice?
    Thanks
    Andy

    Morning,
    As coincidence would have it I just yesterday managed to get mine working. This is what i did in the hope that it helps someone else.
    My problem was that I could create events on the calendar app which would appear in the Outlook calendar (therefore syncing to the exchange server. But events or changes to events done outside of Calendar on mac, werent pulled through.
    As a test I asked the administrator to set me up a blank test email. I then added events from all devices and moved them around and all worked fine. This proved to me it was a problem restricted to Calendar app and my account. The only thing i could think of was that there was an old event stuck in the system somewhere that was causing problem syncing so I deleted my account and cleared my cache and all worked fine!
    To clear my cache:
    Finder
    Go menu while holding Alt key
    Library
    Caches
    Delete:
    ~/Library/Calendars/Calendar Cache
    ~/Library/Caches/com.apple.iCal
    I then set up my exchange account as per normal.

    I have the original iPhone and I can't sync the address book from my Mac to the iPhone. What should be the problem and can I sync?

    Thanks a lot for the answer. I'm so upset, have no even one contact on my phone. I has to do with the moving to iCloud from MobileMe.
    I did exactly what you wrote, and when trying to click the vcf file on the iPhone the screen freezing, and then after few long seconds it goes alon to home.
    So I tried less contacts in a Vcard, and i'm dividing my address book, doing little by little and it work.
    Thank you so much.
    I still dont get why the sync with my computer address book is not working.
    And why when I moved to icloud all the photos I had next to the contacts are disappered.
    I had my iPad, which it still, I did not move from MobileMe to iCloud and all the photos are there!
    Anything I can do to use the iCloud on the iPad as well and update the iCloud with the photos?

    There may be several that were bought with your Apple ID. but somewhere in the updates there must be one associated with that other ID.
    You can update one by one, until you find the one that requires the other Apple ID.

  • IPhone to Exchange calendar sync issues

    OK, I have read through many posts on here, but have yet to find a post that describes my situation. If someone has seen this answered in other places, please let me know.
    I currently have the following setup:
    iPhone 2.2.1, using OTA sync with Exchange
    Entourage 2008 (not Outlook/Windows)
    Exchange server 2007 (at work, I am not the guy who runs it)
    My mail and contacts work fine.
    CALENDAR issue for me is something I can't quite wrap my head around:
    I get syncs fine for calendar when accepted through Entourage - but when they are updated by the original senders I get multiple entries for every event showing up on my phone (the old events aren't removed). In addition, my phone does not sync back to the Exchange server when I accept invitations, nor when I create entries in my calendar.
    Thoughts?

    This problem is only something I've had problems with recently. Previously entries in the Calendar would sync OK regardless of where they were created or accepted. So appointments I logged on the road into the phone would work back into Exchange and onto Entourage.
    Two things have changed. Our Exchange server was upgraded and how has Active Sync which means I now get push notifications which is great. I've also gone up to the 3.01 software on the iPhone.
    Now, it seems I am ONLY getting push from Exchange to the iPhone. Calendar entries from Entourage appear on the phone.
    Any calendar entries created on the phone or invites accepted on the phone stay on the phone. They are not synced back to Exchange and onto my Entourage calendar.
    As someone who is office based for only a few days a month, effective Calendar sync is vital.
    If the problem is with the OS update on the phone then this fix needs to be part of 3.02. If the problem lies with the Active Sync setup then I need some instructions to go back to our Sys Admins with.
    Thanks!

  • Microsoft exchange calendar sync issue in iOS 5.0.1

    Hi,
    I have iPhone 4 with iOS 5.0.1 installed. My company uses Miycrosoft Exchange Server and I have synched my iPhone using the Microsoft Exchange server account option. I don't have any probelm with my emails or contacts.
    However, the calendar is not synching properly. After I setup the account for the first time, I see many of my calendar items has been synced. But some of them are missing. I can't find any reason why those items are missing. I added/deleted new items on my calendar on Outlook Web Access and it showed up on my iPhone. I also tried adding/deleting items on my iPhone and they synched appropriately. The only issue is some of the pre-existing items are not showin on my iPhone and I can't find any reason for it.
    I already tried to delete the account and add from scratch. I also removed the iCloud from my iPhone and tested without iCloud, no difference. I reinstalled the iCloud.
    Any help is much appreciated.

    We have struggled with this as well on Exchange 2010. We just trued this today with some of our users and seems to get everything back into sync:
    On the iOS device:
    • Navigate to Settings app > Mail, Contacts, Calendar.
    • Scroll down and locate the Calendar section
    • Tap Sync (under the Calendars section)
    • Set the interval to All Events
    • Close the Settings app (Tap Home button)
    I suggest rebooting the iOS device. Check the calendar and let it sync – look for those missing events.
    This has worked for everyone that had the missing events issue.

  • Exchange Calendar  Sync Issues List

    I have noticed three things that are driving me insane and wonder if anyone else is having the same problems and/or has found a fix for the problems below.
    1. If you add an appointment in Outlook with categories, by editing it with the iPhone in any way, it clears the categories every time consistently. This is a huge issue for us!
    2. You cannot add a private appointment from the iPhone
    3. You cannot change the view in the calendar on the iPhone. The default view is to see all the appointments in 30 minute increments, I need this to be in 15 minute increments.
    Anyone else what to add to the list? I figured we can list it all here so that Apple has a reference to see some of the issues we are having.
    Thanks,

    Hmm, i jut bought an iPhone 3g and imust say it has not impressed me with regards to its Exchange capabilities. some of my dissatisfaction are as follows:
    - cannot customise calendar, sms , alarm sounds. the default sounds are just too soft and short and i have missed a couple of my appointments. Plus, there is no blinking light to tell u if u have a missed call, sms or appointment/reminder, sigh...
    - the contacts in iphone are also not very smart. u have to key in your telephone no. together with the + and country code, else, when u receive a ring/sms, it will not show u the person from your contacts but merely a number;
    - i can't load any of my mp3 songs as my ringtone or my calendar or my sms alerts as Apple specifies the ringtone has to be <30 seconds and no customisation for sms/reminders...sigh...;
    - also, if i open up any office documents >1mb, my iphone crashes or simply doesnt open them;
    - i share some of my calendar with my staff. In my previous Sony Ericsson P990i, when i enter an appointment, i could mark personal appointment/reminders as "private". iphone doesnt allow me to do so hence, the whole world knows my appointment...sigh..;
    - iphone doesnt allow u to sync with microsoft outlook notes...sigh...
    i sincerely hope there will be a new update from apple to address all these issues if it wants to attract the business market...

  • Exchange calendar sync issues among iOS devices and Mavericks

    When I add an event to a shared Exchange calendar on my Mac in iCal, and mark it as All-Day, that designation does not appear with the event on my iOS devices. Instead, it's given a 24-hour duration from 12 to 12, so to speak. Here's the confusing part: If I edit the event on my iPhone to correct it as All-Day, it does not sync that All-Day designation to my iPad. Additionally, if I then make the same correction on the iPad, toggles it on the phone and removes All-Day. Removal of All-Day designation on a device does remove it on the Mac calendar, which I then have to change back. So I chase it around in a circle and end up with the correct duration on only one iOS device. The difference in All-Day and 24 hours duration does matter graphically as many of these events run for several weeks or months. All-Day keeps them confined to the upper section of the calendar graph rather than muddying up the lowerm hourly appointments.
    Any ideas on how to rectify the problem?
    I'm running Mavericks, iOS 7.0.3 and using MS Exchange 2010.

    There are several other posters on the Forums that are having issues with Exchange sync'ing with Mavericks. It could be that your all-day verses mutli-hour issue may be among them.
    Most of the problems that people are seeing, including myself, are more to do with Mail and Calendar simply not synchronizing.
    My Mail.app INBOX for my Exchange server is now several hours behind my iOS and Windows Outlook instances. Calendar appointments are simply not being pushed to the server (though they seem to be retrieved OK).
    So, sorry for now help on this one directly, but you are not alone.
