So it appears the calendar app has some sort of a bug in it. I have noticed it a few times now, before a reminder in the calendar goes off, a wakelock pops up in betterbatterystats that says 'StartingAlertService' (Calendar). This most recent time it kept my phone awake for over an hour before I killed the calendar. Anybody else notice this? And more important, have a way to fix it?

I actually noticed this on mine for a couple days in a row not to long ago. Haven't seen it again but i've been keeping an eye out. Curious to know why?

I found the source code that call the wakelock of StartingAlertService here.
I am not a dev, but I can see that in order for the wakelock to be released, there are 2 IF statements that have to be satisfied. I think the problem might be there. Any Devs here would like to share any insights??

Had it happen to me once too... I'll look at the code if I can find some time.

Looks like the first if is a simple "is there a wakelock"

The second one appears to be "is something done with doing stuff".

We've had this problem on the international Galaxy S II for a while now. There is a thread on it here: http://xdaforums.com/showthread.php?t=1192696

One problem I see is that the source is for the Android AOSP calendar, which is probably different from the Samsung calendar (just like the Email app is different). I haven't tried the AOSP calendar but typically the Samsung apps have more features. You would have to edit the smali files to fix the Samsung app (or do a crude replacement hack like my Exchange wakelock hack, and pray that it works).

In the meantime, my solution was to just uninstall Calendar. Works great, but now I have no calendar. ;) Other users have uninstalled Calendar and used replacement calendar apps without the wakelock issue, so you could try that.

EDIT: I also noticed that one user mentioned that this bug only happens when Calendar notifications are set to "Off." Kinda counterintuitive, but try setting Calendar notifications to something other than "Off" and see if that fixes the problem.

Came across this earlier today: http://xdaforums.com/showthread.php?p=16699746

I pushed that Calender.apk and froze the TW Calender in Titanium, I set a number of events like normal and so far I have not see the StartingAlertService Wakelock pop up at all, I'll continue to test for a few days and see what happens.

I am surprised this was caught so late. I actually seen this problem 2 days after I bought the ATT SGS2... but I read over in the Intl forum, and decided it was best to get a more "complete" calendar replacement.

UPDATE: I think setting the Calendar notification setting to "Alert" avoids the wakelock issue. When I set it to "Status bar notification" or "Off", I get the wakelock. Give it a try and see if it helps.

Personally I'd rather just have the status bar notifications though. Having to dismiss the popup alert is a pain.

Using the original Android Calendar might be one solution, but I actually like the Samsung apps. Maybe we can just replace the relevant smali file, like I did with my Samsung Email app "fix".

UPDATE 2: Setting the Calendar notification setting to "Alert" seemed to help, but I eventually got another wakelock. So we still need a more reliable solution to this issue.

I experienced this issue. Here's the thread. It has happened since that thread died, but oddly hasn't occurred in the last week or so. I haven't seen any type of consistent behavior. Sometimes it happens, and other times it'll completely stop for a while.

This wouldn't be an option for me. I keep my calendar notifications in my status bar for a while and dismiss them when I don't need them.

Changing to alert didn't seem to work for me, had a 36 min wakelock last night. Back to testing the stock Android calendar.

Well my battery life was plummeting today and I couldn't figure out why. I had an alert for a meeting today at 11AM (it's 5:41PM right now). I just looked in BBS and showed this under partial wakelocks for 1hr 39mins. I went in and deleted the appointment and the service was still increasing. I pulled the battery and now it only shows 37mins under BBS. The time is no longer increasing after a few mins.

I did have notification set to Status Bar Notification, now changed to Alert and will see how it goes from here.

That's peculiar. It didn't really affect my battery.

Yeah "plummeting" might have been an exaggeration but I definitely noticed a faster battery drain than normal. Usually get around 1-2% loss per hour but was getting close to 5% today. All in sleep as I was working all afternoon.

When I get them it puts a big drain on my battery like that as well.

Today I got a wakelock even though my Calendar notification was set to "Alert" (same thing as what hlb3 reported earlier). So it seems this is not a reliable solution after all. Hope somebody is able to make some progress on this.

I've modified TouchWizCalendar.apk with backsmali to force the wakelock release
something like:
Original:
Code: 
if (mStartingService != null) {
   if (service.stopSelfResult(startId)) {
     mStartingService.release();
  }
}
Now:
Code: 
if (mStartingService != null) {
  service.stopSelfResult(startId);
  mStartingService.release();              
}

In finishStartingService function in AlertReceiver.smali I've commented (#) the if
Code: 
    invoke-virtual {p0, p1}, Landroid/app/Service;->stopSelfResult(I)Z

    move-result v1

#    if-eqz v1, :cond_12

    .line 125
    sget-object v1, Lcom/android/calendar/AlertReceiver;->mStartingService:Landroid/os/PowerManager$WakeLock;

My new TouchWizCalendar.apk (XXKI4 stock ROM) is attached but I've not tested it a lot
You only need to overwrite it in /system/app with rootexplorer for example (maybe you need to clear dalvik cache,also delete calendar data, I'm not sure). If works I can create CWM file.
Try TouchWizCalendarV2(notCWM).zip first (based on Serendipity), it's not a CWM file you will have to decompress it and replace.

    ok, the real StartingAlertService Wakelock fix is replace the handleMessage function in AlertService$ServiceHandler.smali in TouchWizCalendar.apk with:

    Code: 
    # virtual methods
.method public handleMessage(Landroid/os/Message;)V
    .registers 4
    .parameter "msg"

    .prologue

    iget-object v0, p0, Lcom/android/calendar/AlertService$ServiceHandler;->this$0:Lcom/android/calendar/AlertService;

    invoke-virtual {v0, p1}, Lcom/android/calendar/AlertService;->processMessage(Landroid/os/Message;)V

    iget-object v0, p0, Lcom/android/calendar/AlertService$ServiceHandler;->this$0:Lcom/android/calendar/AlertService;

    iget v1, p1, Landroid/os/Message;->arg1:I

    invoke-static {v0, v1}, Lcom/android/calendar/AlertReceiver;->finishStartingService(Landroid/app/Service;I)V

    return-void
.end method

    I'm posting the fix because seems that new samsung rom based in 2.3.6 has the bug
    So if anyone wants to test you can try to replace the attached TouchWizCalendar.apk (make a backup of the original) in this post, if doesn't work then upload the original apk and I'll patch it.
    The patched TouchWizCalendar.apk is from Checkrom RevoHD 3.1.1 not sue if all roms use the same apk

    Ok, did a littke testing and under normal situations it has taken care of the wakelock. I found if you create or edit an event with a reminder to go off in like 30 min or so it will wakelock until it notifies you, then it stops. That was the only time I could get it to do a wakelock, so far it is looking promising.
