Hi there,
I finally fixed my battery drain problem, thanks to LiverpoolFCfan (http://forum.xda-developers.com/showthread.php?t=1210184).
The automatic calendar sync tries to get appointments for the birthday entries in the contacts. If the calendar sync doesn't find any matching appointment, it will enter a loop where it constantly polls to find these appointments.
I just delete all Birthdays from my contacts for diagnosis purposes, and now it's all fine
I have less than 1% battery drainage in idle now with push main enabled
Typical indicators:
- sync symbol for calendar (vanishes after some secs) in Settings->Accounts->(Exchange Acc)
- High Usage of "Android OS" and "Mail"(strange, I know) in the Battery Stats
- Battery drain vanishes if automatic calendar sync is disabled
I don't know, if it's only an Exchange Sync Bug or affects the Google Acc. as well , as I don't give Google my contacts' data
Hope this helps anyone.

Huh, good to know. I'll have to play around with it. If it's that big of a problem I guess we can always disable it on days we need the extra battery and stick with web apps/book mark for Calendar information.

Hi all,
A few days into my Desire Z experience and I'm very happy.
However, battery life is somewhat low, probably because of the "wow" factor of constant playing but dropping 20% overnight was a bit perplexing, even my Windows 6.5.x phone dropped < 5%. I have only installed about 3 apps so far and they're not sync ones.
Playing about reveals that in;
Settings -> Accounts and Sync -> Google
Sync Contacts
Sync GMail
Sync Calendar
Are all checked on and automatically and periodically syncing.
Not using any of these services and HTC Sense requiring the global automatic sync, simply untick all these services. Hopefully battery life will be improved...
It has been suggested in other forums while I was searching for my issue that its much more battery friendly to add your GMail account to the mail app and set a schedule instead of relying on Sync.

If I go under the individual Google account syncing, it shows that my contacts and gmail are constantly syncing. The sync icon doesn't disappear and I'm curious as to whether this is the reason why my sleep time is so bad. Anyone know how to fix this or make it finish syncing?
Hey
is there a possibility to sync time triggered all those stuff which syncing several times per day such as google+ , Calendar, Contacts a.s.o. ??

Syncing is done via Push now. Your phone doesn't periodically go off and sync every few minutes, instead it waits to be told it has something to sync, this is all done through Google Play services, so is battery friendly. If you get lots of notifications this will cause extra battery drain as of course your phone is constantly being nudged to wakeup and alert you to something, so options are to uncheck these from syncing from the Accounts setting page.

Thanx.
What u wrote is correct but nevertheless i want to sync only ones a day.
This without doing it manually by going to the Settings...

I am using Battery Stats Plus and Google Contacts Synch is at the top of Battery, Wake, CPU and GPS usage regularly. All my contacts are on Outlook so I don't have any Google contacts. I stopped the backup and synch of my Google account except emails but it is still there. Does anyone know what is causing this and how to stop it? Thanks in advanced. Just trying to fine tune this awesome phone.
I would like to share a solution that worked for me.
Understand that this worked for me, I am not saying that this will work for you.
I was suffering from a huge battery drain, I noticed that it was coming from "Exchange Services" (I have an Exchange account on the default Email App, specifically an Outlook.com account). The Exchange services were keeping my phone awake all the time and using wifi/mobile data.
What I did was disable Tasks syncronization (I kept email, calendar and contacts synchronization active). Then I changed my syncronization interval from automatic (push) to manual, this did Exchange to stop any data activity, after this I changed back the syncronization interval to automatic (push) again.
So the problem I found is that Exchange services couldn't syncronize any Tasks, it was just trying... and trying... while this my phone was being awake, downloading a lot of data (almost 1MB per minute) and draining my battery (1% every 2~3minutes).
So if you're having battery drain and uses an Exchange account on your phone, you won't get hurt for trying this
