gmail push

Does push Gmail require my data connection to be on all the time? If so, how much battery drain does a constant data connection cause?

no. ur using activesync so u have d choice of setting it to manual sync, or interval or immediate (always on)
if ur using edge, expect 8-9 hours.
3g, 6 hours top.

I’d just like to add my 2 cents in this so that people don’t get turned off by push email…
I happen to connect to an Exchange Server via Active Sync for my email. For 14 hrs a day, it’s set to sync “as items arrive” (i.e. push). During the night, I set the sync schedule to “manual”.
I get a moderate amount of emails each day and I have to say that I’ve not notice a substantial battery drain relative to an IMAP connection that polls every hour.
Push email doesn't require a constant connection as if you're always downloading something. It's more of a "pulse" connection. Try to research a bit into exactly how push email works and you'll see what I mean...

There are two ways to push gmail (or two that I've used recently). One is the new gmail sync, which is an Exchange server. Using that method, I was getting about 8 hours of battery.
The other method is the System Seven beta. I used this for a year+ on my Moto Q before gmail sync became available. I don't know how System Seven works -- it's not Exchange and it's not IMAP. But it works. It seems to be more reliable and quicker than gmail sync, at least for now. It never has gmail sync's problem with passing through attachments. On my TP2, with Seven, I can turn Direct Push off in Comm Manager, and I get more than 24 hours of battery. The only funny glitch with Seven is that on the TF3D home messaging tab, in the little envelope on the screen, instead of showing the beginning of the message, it says, "Click to view message." But that's o.k.; I wouldn't read messages on that screen anyway.
I recently switched back from gmail sync to Seven, and for now it's better. I expect that in a short while, gmail sync will iron out some bugs and become more responsive, and maybe I'll switch back.
One feature that neither of them have, and I'm dying for: The ability to synchronize flags, to mark a message as "Follow up" in Pocket Outlook and have it star the message in gmail. Gmail sync allows the flag, and it will sync with Outlook, but not directly with gmail on the web.
System Seven is here: http://community.seven.com/main.php
It's free and seems likely to remain so...

[Q] Exchange Calendar Sync Issue - Resolved

Stock EVO, 2.2...
I just noticed this issue about three days ago...my Exchange calendar is constantly syncing, and I do mean constantly.
If you go to Settings - Accounts & Syc - Exchange ActiveSync, you can see the last sync for each item. My calendar constantly reads the same time as system time, and the Sync icon in my notification area is constantly flashing on and off.
I have noticed that my battery is draining VERY fast. I had to put it on a charger twice yesterday (I got the 15% battery warning) with normal use, when I can typically go a full day of use without any issue.
I can deselect Calendar syncing, but of course that's only a temporary fix.
Has anyone else run into this? Anyone heard of a solution? A google search did not yield any results.

FIXED!!!
Well I fixed my own problem...though I cannot determine the cause of the issue (I even tried uninstalling some apps I had DL over the past few days), the fix was simple, though it took a while to figure out.
I tried to merely remove/re-add my Exchange sync, but I kept getting 'client/server conversion errors', and my calendar would refuse to sync (though email and contacts did). Furthermore, in Outlook, I would get lots of duplicate entries (interestingly, they were recurring events and all-day events).
This was the solution:
1. Delete Exchange account from EVO (contacts, calendar, email)
2. Since I noticed that my calendar app still had some entries in it, even after deleting the Exchange account, it was evident that there was some data still on my phone that was possibly causing the syncing error. So, I went to Settings - Applications - Manage Applications, and selected the All tab. Scroll down to the 'Calendar' app entries, and you have to clear/delete any cache/storage data in each.
3. Re-synced with Exchange successfully.
I searched around different forums, and it seems many have had a similar issue and have waited in vain for Sprint or HTC to publish a solution.
This one worked for me. Hope it helps others.

yes!!!! Thank you so much. After trying everything and almost a week of my battery going dead with a couple of hours on my EVO your solution worked! I would recommend that anyone try this solution before going any further!

[Q] Native ICS email Exchange suddenly wakelocking?

Anyone using Exchange on the native email client suddenly notice a huge battery drain/wakelock with Exchange server?
I haven't changed my email setup in weeks and I've never had this problem before. My phone is a little over 5 hours off charger and at 19%! Exchange services is at 19% with a 1h 13m wakelock on BBS.
I have Gmail and Hotmail (yeah, yeah) accounts both set up as push. Only the Gmail syncs contacts and calendar (I've double-checked everything). I probably get ~20 emails/day or so.
Until today, I would get >24 hours with light usage, and a full day with heavier usage. This literally started today out of the blue.
I searched all of XDA and the GN forums specifically and didn't see anything that addressed this particular issue. Any suggestions?
TIA

Anyone?
The actual service is com.android.exchange.Exchange Services

The weird thing is that it just started doing this, even though I haven't changed any settings in weeks. And not having push email would suck...

This has happened to me from time to time on CM and AOSP ROMs, but not on my GN yet. It's a Google problem IIRC and something that they "fixed" in the past, but they obviously haven't.
I'd observe this 1/10 nightly ROM flashes so I'd keep an eye on it for the first couple of hours afterwards and kill it if it was starting to go rogue.
It's a known, flagged, issue (on Google) but I don't have the link handy.

i noticed similar Exchange Mail behavior on my phone with any ROM that i flashed. i narrowed the constant-sync to my calendar. when i disabled calendar sync, the battery drain stopped. my research suggested the problem was related to a corrupt calendar or recurring calendar entries. so i archived all my Exchange calendar entries (which removed them from my calendar) removed then re-added the Exchange account to my phone and finally restored the calendar entries i needed. so far, no issues and i've flashed 3 ROMs and the problem has not returned. somewhat extreme, but it worked!

I have no issues with stock Exchange and Gmail apps on rooted 4.0.4.
You could try deleting and recreating the email accounts to see if that helps.

Also got the issue this night. 25% gone after 4 hours sleep, wakelock because of the Exchange service ... Disabled google sync, then reenabled it 2 hours later, and no problem ... It gets stuck somehow sometimes ...

I had the same problem on my SGS2 on ICS. I finally had no choice but to migrate my email to Google Apps. In the end it was the best decision since the Archive function on the GMail app is amazing and it simply works 10x better than any Exchange ActiveSync client.
The Google Apps connector for Outlook also works almost as well as Exchange Server.

Emails do not auto-sync

I've noticed that after I wake up, my new emails are not showing up. When I check my email app it says "last synced yesterday at x:xx". Right now I have it set at peak hours 6am-10pm 7 days a week refreshing every hour. I have checked my email at hours after i wake up at 7 and it will update when I open it. Afterwards it will sync every hour as normal. I think this is only happening when it's trying to come back from off-peak hours (which is set to never sync).
I've tried removing all accounts and deleting all app data but to no effect. My auto sync is on for everything including under settings > data usage. One thing I have noticed is that when you go to settings > email > [my account], the "last synced" time is different than if you go into the email app and see the "last synced" time.
I cant confirm but does not seem to be happening to my gmail account.
Anyone else having this issue?
Specs:
-T-889 on 7105 international rom by teshxx, dalvik/cache wiped.
-yahoo IMAP email
-no battery savers or anything that touches auto sync

Your probably saving battery
If your Gmail isn't syncing it probably isn't draining your battery, just saying.

I do not have any problems with my gmail app..

In case anyone still has issues with this, I've found the solution. For incoming settings for yahoo mail you must use samsung.imap.mail.yahoo.com, I was only using imap.mail.yahoo.com which caused my phone (for some reason) to not sync initially when entering peak hours.

[Q] Email Sync Issue

I am having a weird issue with email syncing. I have several email and exchange accounts set up with syncing scheduled for every 5 minutes (and push for the exchange accounts) with peak times disabled so that it is supposed to sync every 5 minutes 24/7. I have this exact same setup on my galaxy s3 without issue.
The problem is that 8AM and 5PM everyday syncing stops and will not continue automatic syncing unless I manually sync one time. For example, email was syncing every 5 minutes as schedule before 8AM. Now once it turns 8AM, it does not sync automatically anymore. Around 9AM, I check, and the last sync is anywhere between 7:55AM and 8:04AM. Now once I manually sync once after 8AM, the phone syncs every 5 minutes until 5PM. The same problem occurs again and the phone does not automatically sync until I do one manual sync.
I am on my home wifi network at both times (8AM and 5PM), but it occurs regardless of wifi or mobile data, and I have ensured that master sync is enabled, and under the data usage settings, auto-sync data is enabled, and restrict background data is unchecked.
I have tried restarting the phone. I also cleared all email data and cache from the application menu and deleting the cache from recovery. I then renetered all my email accounts, and the same issue occurred on the dot at 8AM.
My phone is rooted with CWM recovery, but this issue occurred before I even rooted my phone. Any help would be appreciated. Thanks in advance.

No one else has this issue? I find that hard to believe. I installed the Wicked ROM, and the same exact issue is occurring as in the original stock rom.

Did you try to enable peak times and under peak settings set to every 5 minutes? I don't know as I have mine manual to save battery, couldn't imagine how quick my Battery would die pushing e mail every 5 minutes

Yeah I did try enabling peak times every 5 mins but it didnt work. Battery life isnt too bad, I work nights now and it lasts the entire 12 hour shift with moderate use.

I have isolated the issue. It seems like having multiple exchange accounts causes this issue. All my exchange accounts are outlook (ie hotmail). So after I removed all of them except my primary, it is now syncing without issue. This is a serious bug that was introduced in the GS4, as my GS3 does not have this problem.
I am curious is anybody with multiple exchange accounts having or not having this issue?
