Hey guys-
I recently went from Liberated b005 to the FR008 and everything is working great except one thing: Exchange ActiveSync.
I have my normal email with gmail, and my business email & calendar is on Exchange. I am using the HTC "Mail" app on the phone. The problem is that it does not get the mail in a timely fashion. With the previous Liberated b005 Eclair it worked perfectly, just as expected, with no tweaking required. I'd get mail on my phone within a few minutes of when I got it on my PC. But now I generally have to open the Mail app and manually refresh it to get any Exchange mail.
Under "Accounts & sync" settings, I have "Background data" checked and "Auto-sync" (which I understand is aka "push email") is unchecked. Maybe it works right with Auto-sync checked but my battery life is horrible with it set that way.
I have "Exchange ActiveSync" account
Under "Data and synchronization" for that account, it has:
Schedule: Manual
Sync mail: checked
Sync contacts: not checked
Sync calendar: checked
If I click "Schedule", it has "Peak time" which is Mon-Fri 7:30am-7:00pm, and then "Frequency" Peak times: Every 15 minutes and Off-peak times: Every hour
I don't recall these "peak time" and etc. from the b005 settings. It just seemed to work as expected without me having to fool with it.
Any ideas why this isn't syncing my mail ever 15 minutes as I would expect during "peak time"?
Oh and by the way, thanks attn1 for the ROMs. This stuff is brilliant.
i don't think theres anything particularly wrong with what the app is doing.
you put that the schedule is manual...rather than you manually setting it, perhaps it means it only refreshes when you refresh it manually?
i would set it to auto sync and perhaps change a few other things to manage battery life better? disable gps/wifi when not needed, lower screen brightness all that stuff.
i know i'm not extraordinarily helpful, but thats all i've got.
Well, clearly under the "manual" settings, it appears that it's supposed to be doing something automatically.
I already manage gps & wifi and all that other stuff to improve battery life. I still have to charge the phone mid-day. Turning on Auto-sync may "fix" my mail issue (work around it, really), but the cost is way too high in terms of battery life.

I have my exchange account set as follows:
Days: Every day
Peak time start: 05:00
Peak time end: 22:00
Peak times: As items arrive
Off-peak times: Every 4 hours
Works brilliantly.
First off I think "Auto-sync" being off is your issue. I do not believe that the "Auto-sync" setting refers to "push mail". I believe the auto-sync setting is general for all apps and how they are allowed to sync data either manual or automagically, where as push mail has to do with your mail client only. I believe setting your exchange account to receive items as they arrive is "push mail". I have Auto-sync enabled.
Think of it this way, your schedule settings are for the exchange app in particular where as the "auto-sync" setting is for all apps that use a data connection so no matter what you specify in the app settings, the general data sync settings will over ride them. By turning off auto-sync you are telling your phone to not allow any app to sync on it's own but to allow the app to sync when it is launched manually.
The only other thought that comes to mind is that if you are using wifi and connected to the same network that your exchange server is on, your phone will not be able to sync your mail unless you turn off your wifi or you have your wifi set to sleep after 15 minutes of phone sleep. Once your wifi sleeps your exchange mail will use the carrier network and be able to sync.
OK, I get it.
"Background Data" is aka "push"? Or, in other words, there is no way to allow a timed sync like a normal old fashioned email app, while also disabling push email, correct?

Push refers to how an exchange server sends email to your mobile client, it has nothing to do with the "background data" or "auto-sync" settings. No matter how you want your exchange client to sync, either timed like every 5 minutes or immediately when items are received, you have to have "auto-sync" enabled for it to work.
Let's break it down like this:
With "auto-sync" enabled your mail should update per the schedule you set automatically without launching the app.
With "auto-sync" disabled your mail will only update when you launch it from the application shortcut.
Does that make sense?
NOTE: Background data must be enabled as well.

turning on auto sync isn't a work-around; as a$$h4t pointed out, it is a solution. for your phone to grab mail as per your schedule, auto sync must be enabled.
as far as your battery woes go, i'm at a loss as to how it could be draining so much if you already manage your battery life pretty well. i would install the app watchdog task manager to keep an eye on any processes trying to eat more battery than they need to.
also, a readthrough of this tutorial never hurts.

The Background/Auto-sync settings are purely advisory, and many apps ignore them completely. To change the HTC mail sync behavior you need to change the settings in the HTC mail prefs.
When you do set Background and/or Auto-sync, most of the Google apps (and some of the HTC ones) start polling the network regularly, which is what kills your battery. Weather, stocks, gmail, etc etc. In my experience it takes quite a lot of tweaking to run them all down. Once done though, I've been able to re-enable those global settings without killing the battery.
thanks for the tips. Auto-sync is working fine now with Exchange and it's not draining the battery unduly, well not any more than it drains it with auto-sync turned off.
I can't seem to remove apps like News & Weather, GMail, Stocks, etc. that would use background data services and which I do not ever use. Guess I can just delete the apk files.

You can go into settings under "Accounts & sync" and go into each account that you don't want to sync and uncheck sync. I usually do that with news, stocks and weather right off the bat when I set up a phone. That will cut down on the background data and help with your battery life.

you can remove certain system apps via this method. i always do this for facebook, news/weather, stocks and things like that.
and for more battery help, check this out.
thanks. i'll check it out. location-based wifi would be the bomb for battery saving, but Y5 does not work on Froyo/Aria and everything else that has this feature is a paid app... guess I just am not yet willing to spring for it. Cheap == me.
Found HTC HUB kept syncing every 3 minutes. This may be a bug in Sense 3.0 but not sure. My battery is no longer losing 4/5% per hour without use. Not saying this will solve everyone's battery life problems but give it ago. Also turned Facebook sync off.
Hope this helps some of you guys.

As a general rule, sync management should always be in play...especially on a brand new phone. This includes email. Push email eats battery badly. Also included in this is location settings and brand specific apps. Very few people think of HTC hub.

Actually Polling email affects the battery more than push. Polling your phone will connect every X amount of minutes to poll the server for new mail so it's constantly using data every time it checks. Push email the emails are only pushed to the phone when there are new messages so data is only used when the server pushes the message to your phone instead of your phone connecting to poll your email account every 15 minutes or every hour, sending data to the server, the server checking if there are messages, then pulling the data down.
There has been debate on this but think about it.
if you poll for email every 15 minutes the phone is opening a data connection to the server every 15 minutes even if there are no messages. with push you only use data when the message is pushed to you.

i was doing this before but i wasnt seeing HTC Sense thats y i asked, but i just realized its because it wasnt added to the list yet, so i just dint add it since im not even using it
Yeah i turned it off and im lasting a day and a half now. I like it but it's not worth all that battery life.

HTC Hub is useless anyway. I don't know why anyone would want to use it.

When you have the two check boxes to sync htc hub and htc sync checked what info does it sync anyway?

my guess is the hub is to let you know of new widgets & crap & htc sync is is for their online site that can locate your phone, backs up your contacts/sms, & all of that
Honestly the screen is the culprit of battery drainage on my phone. I turned it all the way down and its been 5 hours and my battery is still 93%

Mine too. I found that friendstream was the actual culprit. Even though it said "Display" i discovered that that includes widgets also. Took friendstream off my desktop and unchecked the HTC HUB & SYNC and I'm perfect now.

I think you misunderstand push vs pull in this context.
Pretty much all home WiFi routers as well as many mobile operators put your phone behind NAT. Also, every time you change networks your phone may end up with a different IP address. This means your phone is effectively unreachable for push messages in the way that you describe: sitting idle waiting for a message.
To be addressable by the push server it will need to poll each time it changes IP. To work around the NAT issue it will need to poll frequently regardless of IP changes, just to keep an open channel. (This because NAT mappings time out after a short while.) Push in the traditional sense is cool just because your message arrive instantly.
The idea that push saves battery is really just because of how Apple introduced push. They don't allow other apps to poll or to keep a traditional push connections open in the background. Instead they force all apps to use their push system, which results in a number of battery savings:
* Keeping 1 channel open with Apple's server vs. tons of poll/push connections with various servers is more efficient, simply because there is much less activity.
* That 1 channel is kept open with a specifically designed and very efficient protocol. It's not exchanging a lot of data just to keep the connection alive. (E.g. when you poll your e-mail you have a TCP handshake, an SSL handshake, an IMAP login and then a message list; much less efficient than the simple poll done by Apple.)
* Since no apps are pushing or polling themselves, they can be terminated or suspended completely without running stuff in the background. They don't wake up until the user responds to an Apple push message.

I don't use hub or sense (though Sense is always listed in my running apps). My question is my screen is always 95% of the drain. You indicate that widgets are also included in the mix. I have Pure Messenger widgets, doubletwist (which is ALWAYS running even when its not a widget or activated by me), FB for android, Twitter, Twidroid and Friendcaster as widgets on my screens. However, I have Fcaster, Twitter, Twidroid and Pure messenger (for g-mail) polling every 4 hours. I am getting killed when I perform any extended action like taking a few pics and talking on the phone. If I open up any FB app I can watch the battery start to tick backwards like an odometer. Are these widgets responsible for this, though they are are scheduled for polling?

So traditionally push would usually take up less battery life? (with Apple, Blackberry) but with Android it eats more battery? hmm I like to get my mail pretty quickly so setting my email to poll every 15 minutes takes up less battery then if it was pushed? It just seems odd that it would eat more battery with android but the opposite on apple and BB devices (I only know about BB never owned an iphone or ipad, never will)

How much of a battery increase did you notice from removing friend stream? I had the friend stream widget and just removed it. Hopefully that will help. I also use the HTC calendar widget, mail widget, weather widget and message widget

I go from generally...well..let me give u today's numbers.
5:11pm Unplugged at 100%
8:54pm 74% with moderate usage. (Tweetdeck, 47 texts, Google Talk non stop, 5 phone calls about 15 minutes or so a piece)
I only have Engadget, Bookmarks, Google Music and power Widget on Display and I am doing great... i generally recharge once a day now.
So I am 100% sure Friendstream is the Display killer for battery and HTC Sense is the other culprit...Disable these 2 and you will see what I mean.

I think he meant to disable HTC Hub from sync as mentioned earlier. If you use an alternative launcher I think you can use a task killer or app like android assistant to kill HTC Sense at start up. because even if you use another launcher it still runs in the background

I was kinda thinking the same and will be trying Zeam...thanks
As we all know, keeping "activesync" on would drain your Android phone's battery pretty quickly. but if i turn in off, "push" does not work. when a thrid party app like K-9 mail can deliver mail almsot at real times with only background data on(and push off) why cant we get same functionality on stock gmail app?
I am having consistency issues with the dialer and setting issues with exchange email. It seems as thought the dialer does not search the first name any more but doesn't always search the last name either. I cannot figure out why it works sometimes and not others. Also, It seems the update negated any of the exchange sync settings. For instance, i have mine set to sync every 15 minutes during peak and none on off peak but it push emails all of the time. Which may explain the loss of battery life.
Any thoughts?

So I kind of figured it out on my own.... The dialer is just very slow to process. If you dial too quickly it does not filter the names in your contacts at all. Email, I master reset my phone which corrected the exchange sync issue.
I sync my corporate email with our exchange server. I am curious, what do you guys think use more battery: polling every 5 minutes or push?
I would think the polling every 5 would... cuz it's doing that even when there may be a long stretch of time inbetween emails you get.
I use push and really don't notice any detrimental effect on the battery.
I would think push as well. There has to be some sort of service that runs on your device to facilitate pushing (C2DM), but it will be running regardless of whether the email app uses it since other apps such as google play need it. Polling on the other hand would be something running specifically for the email app...I think :silly:
