Could this be an underlying cause of poor battery life? (not that it’s that bad in my opinion – seem to get 15-20 hrs out of one charge – But my Hero could last 2 days or more)
Would someone please bother to retrace my steps on their devices to see if they get the same results?
UPDATE APRIL 21 2010: PARTIAL SOLUTION FOUND: The problem is the calendar app. It can be solved partially by force closing the calendar in “manage applications” and then starting it up again. After doing this, the phone sleeps correctly. So something in the calendar app is preventing the phone from going to sleep – And by restarting the app it works correctly again.
Unfortunately this is only a temporary fix, since it has to be done every time the phone is powered on (rebooted) and also every once in a while without rebooting, since the calendar app for some reason resumes it bad behaviour after a day or so.
So everyone with the problem should let HTC know about it - Assuming they listen..
UPDATE APRIL 24 2010: SCREENSHOTS ADDED: I added screenshots of the issue as well as how it's supposed to look on a handset without the issue.
UPDATE APRIL 28 2010: PERMANENT SOLUTION FOUND?: Remove Flickr Sync. Go to Settings>Accounts & Sync>Flickr. Then press remove account at the bottom of the screen and reboot the phone - Please report back in the thread if successful! :)
UPDATE JUNE 07 2010: The issue has been resolved by OTA update to 1.21.405.2.
