Killing Calendar and OBEX services stops HTC Sync

[twisted_mind]

I started killing the calendar and the obex services by going into settings>applications>running services.
This is resulted in the awake times significantly lower than the up time... however today i realised it also means when i want to connect the Desire to the pc to sync contacts/calendar with outlook.. the sync software on the phone does not launch at all. I went into the programs menu, but there is no launcher icon for the sync app.

I also setup the power control widget that comes with the phone on the homescreen and enabled sync from that... no go. The Sync app only came up when i rebooted the device and *DID NOT* kill the two calendar processes on the phone.

Any workaround?? I know rebooting is a solution, but i would appreciate if there's something quicker.

If you kill the calendar app you cant sync it, and OBEX is used for much more than just the calendar.

Becareful what you kill as it can have unforseen issues with other apps.

I do the same as the op. I also stop gtalk. I leave the one callender app running that says connectivity services, but the obex calender i stop. I haven't had any issues so far. If i wanna connect to my pc ill just reboot. Any issues with this? What else gets effected?

@dunbad
i also reboot the device whenever i want to sync. Not a big hassle but i was just wondering if there was something i could do about it... anyways thanks for reply

Sorry I couldn't help. But im curious as to wether or not you can update your accounts (refresh) with the connectivity calender stopped? I leave that one open and have no issues refreshing my gmail account for instance from the power control widget. It appears that going into calender and refreshing though does not return "calender connectivity" to the running services.

You could try not killing the service...?

not killing the service results in up times = awake times = significantly lower battery life

 

[lekky]

Are you sure it has significantly lower battery life? Theres no way around it if you insist on killing system processes!

 

[twisted_mind]

^^ yes lekky
i have noticed my battery lasting much longer since i started killing the obex process that auto-starts at reboot.

 

[lekky]

what does the obex process do? If you find that out then you may find the app that uses the process so much as to make your phone have a shorter batterylife, maybe

It defeats me why anybody feels the need to blindly end processes on the Desire. There is no gain in phone performance and battery life.

It's a placebo.

There was/is a bug that makes the battery drain with the calendar. For some reason it will keep the phone awake 100% of the time (under battery info there is a difference between 'Up Time' and 'Awake time').

Have you got a Flickr account sycned to your phone? That's what caused the problem for me... deleting the Flickr account and rebooting resulted in significantly better battery time for me.

 

[twisted_mind]

^^ No Dan, i haven't setup flickr reading as how it was also messing up with the battery life.

The only other thing I could think of doing would be to just experiment with different sync settings for everything, maybe you'll get lucky and find the culprit.

You could try trawling through this thread to see if anyone has a similar problem to you (i.e. no Flickr account). Other than that, I'm all out of helpful advice short of factory resetting/getting the phone replaced.

What provider are you with? Some companies use there own ROMs.

 

[twisted_mind]

Aye Dan.. i'm using the desire in India. It was bought as a T-mobile branded device.. but since then i have unbranded it using the modaco r3 rom.
So far i have just gmail and yahoomail set to download new mails once a day. No other auto-sync for any apps.

Well, I have to agree with the op. I have not got task killers even installed on my phone. I just leave everything in the background. But this obex thing is a running process is indicating. Since stopping it, ive noticed no bad effect on my phone at all. And a decent battery performance gain. Now the gain may unrelated as ive done a few things (with same usage) but so ling as theres no bad effect, or restrictions that effect me, i dont see the harm. Like ive said already, I also stop gtalk, as I dont use it. But everything else i dont touch

I shared this in another post.....but thought I would share it too as well.

Obex service:

Object Exchange: a set of high-level protocols allowing objects such as vCard contact information and vCalendar schedule entries to be exchanged using either IrDA (IrOBEX) or Bluetooth. Symbian OS implements IrOBEX for exchange of vCards, for example between a Nokia 9210 Communicator and an Ericsson R380 Smartphone, and vCalendar.

Killing this has improved my battery life and I haven't lost any features.
