Set up my works Exchange account on the S3 and suspected it was causing high battery drain.
Selected some 'sleep time' from within the application and then also selected Manual Update so I could save battery. It appears manual doesn't change anything though as my mail still comes through unless I deactivated the account completely?
Anyone else have this issue.?

That wouldn't be a bug in Exchange causing the issue.
It is, most likely, because ActiveSync, which is what Exchange uses to communicate with your phone, is a server-side "push" technology. This means that your phone, most likely, has WiFi and/or your Internet services "always on" to accommodate ActiveSync. ActiveSync doesn't work like Blackberry where the client-side does all of the control/communication (pull technology). It is all done server-side, which means that the phone has to always have an Internet connection, either through WiFi or the phone Internet services, to be ready to accept incoming information from ActiveSync.
Thanks for the reply - so the option to manually retrieve mail is pointless then as it going to get pushed whether I want it or not?

After posting my response, I decided that it could be a little bit clearer, so here goes.
Blackberry (BES specifically), IMAP, POP3, SMTP, etc, the client side, in this case the phone, is in control of all of the message synchronization. Meaning that every n number of minutes/hours/days it opens up an Internet connection and says, "Do you have anything for me? If so, send it now." That's client-side pull technology.
ActiveSync, on the other hand, the server (in this case the Exchange Client Access Server), sends out the info, via AvtiveSync, every time something new comes in to your Exchange mailbox. This happens "real-time" rather than every n number of minutes. This means that the client side, in this case the phone, must have an "always on" Internet connection, either via WiFi or the phone's Internet service, to accept these "real-time" updates. This is server-side push technology.
Server-side push technology, by its very nature, causes the client-side, in this case the phone, to consume more battery since the WiFi and Internet "radios" must always be on.
I hope that this makes more sense than my last post.

Correct. The server is the controlling "party" in the paired relationship.

I ran the same tests on the S3. I'm syncing 3 exchange accounts.
Email exchange service drains the battery really fast ...
Nearly half of the battery is used (battery stats) for this process only [47%].
My battery cannot last:
- on 3G networks, more than 5 hours.
- on WiFi, it goes up to 8 hours.
I used to sync the same exchange accounts on 2 other Samsung devices: Captivate Glide and Galaxy Note - both running Android 2.3.5/2.3.6
=> no issues with the sync services draining the battery.
IMHO, this is not only linked to the Activesync technology, it is also linked android release and the way email exchange service is made/configured (or runs).
There might be some tweaks or possible patch for this service...
But don't know what or where, yet ...
My 2 cents ...
The phone keeps at least one connection to Google open at all times (C2DM push) when it has a network connection.
Open and half-open connections do not really cause high battery drain since your device can (and will) go to lower power states and switch the network to fast dormancy which is a sort of periodic polling for new data.
A scientific article about the topic can be found here: Link (PDF)
The relevant part is in footnote 4 of paragraph 4.1.2
In fact, even at IDLE, a handset periodically wakes up to listen for incoming packets on the paging
channel. If a downlink packet happens to arrive between two paging occasions, it will be delayed until the next paging occasion

Additionally that IMAP is poll-only is not entirely correct. While IMAP itself is usually only used as PULL (client requests, receives, closes connection) many servers support the IMAP IDLE mode (client requests, receives, waits for new data, receives, waits, ...) which is a real push technology.
(Technically it differs from Google's C2DM which in fact is HTTP (Comet) long-polling and not true pushing)
I've noticed a high battery drain on Exchange too, even if the account was disabled. It's unrelated to how the phone is connected (Wifi,3G,2G) and _seems_ to get lower when no data connection is open.
It will only go away if the account is removed and seems to caused by the app waking up all the time even if not needed. Thirdparty apps and stock Android do not seem to have this issue - at least my S1 did not.
(I haven't tested on the S3 with a non-stock app yet)
Btw my Exchange server is a patched Z-Push IMAP/SMTP<->Activesync converter from their trunk with Exchange2007 capabilities.
Yes, there HAS to be a bug in the exchange app on this phone.
I got my phone a month ago, and have had no issues with battery drain and high data usage with Exchange what so ever. Until this weekend.
All of a sudden, with no change in the settings at all, my battery all of a sudden just lasted 5-6 hours. It got really warm too. Then after a day or so, I got a message that my monthly limit of data was reached. I didn´t believe this at all since I had more than 500 MB left on my limit the day before.
But when I checked the settings, I was shocked to see that this was true indeed. And it was "exchange services" that caused this. It had downloaded about 600-700 MBs over this short period, thus (of course) causing my battery to drain quickly, and I will now get a nice bill from my phone company for over use of data
As I said. No changes to the settings were done. This happened over night. And of course this has to be a bug in the app, not a server-issue. No one else in my company, as far as I have heard, had had this issue (yet), but after googling I can see that this actually is a problem for many, with different phone brands.
It seems like google has got complains about this, but there has not been released a fix, which is totally unacceptable. I now have had to turn of my mail sync to prevent the data usage to go insane, and my phone to get warm, slow and quick battery drain.
If this isn´t fixed quickly, I will uninstall Exchange services from my phone (have root), and install Touchdown instead.
Here is the problem discussed:
productforums.google.com/forum/#!topic/mobile/tCA92MdBTmc
- but with no solution.
Issue was resolved by deleting account and reinstalling it. But I had to do it twice before it worked.
I also cleand the Exchange Services App with the tool SD Maid before I reinstalled my account the second time.
My battery is back to normal, and no more crazy data usage.
Hi!
My father has a Samsung Galaxy S2 with the stock GB, and un-rooted. The phone has been working flawlessly, but lately (since about 2-3 days ago) it begun to using a crazy amount of data.
My father normally uses about 300 mb per month, but now the phone is using about 20-30 mb per hour IN STANDBY.
Also he notices that the battery is lasting about half of the previous time which is consistent with a long running process...
He doesn’t install/update anything lately and the settings are set for low data use. Like no auto sync, he also has all the known data eating apps disabled.
He has installed an app call “my data monitor” and the app says that all the data is being used by OS services but there isn't a detailed information.
Just for clarification, he doesn’t have too much applications installed. Just: Whatsapp, Viber, Facebook and Twiter, but as I say before, he has all the auto sync off, and all this apps where installed Months ago.
My question is: there is a program that can help us to find what is going on? Something like a “on the fly” data analysis?
Any other idea what can be happening?
Thanks!
Edgar
First off, turn off data connection. Settings-wireless and networks-mobile network-uncheck "use packet data".
And then go to Accounts and sync in settings and disable all Google account syncing.

Sounds like a virus to me. Download a virus scanner from the play store. And if you have wifi, I would turn on airplane mode then turn on wifi so he's not using his plans data

I already installed Avast, it coming clean. Maybe I will try another AV.
This happened to me too! Tried figuring out what the issue was, but no avail! Data connection continuously ON and the battery draining like crazy. Had to re-flash stock GB and the problem vanished. :victory:
Since I've been using the leaked 4.1 builds I have been burning through Data at an incredible rate, the first month I hit my 2GB monthly allowance after about 3 weeks, which at the time I thought it was just me using it a lot because it was new.
Today however I have been told by my network provider that my 2GB limit for this month was used up in about 4 days!!! After spending most of the day arguing with them they confirmed my phone was connecting every 30-60 seconds & using 200-400mb every time?
After the first month I set all sync options to manual & I don't use Facebook etc. but with Samsung swapping all the settings menu around it seems there are some extra sync options I missed, Maps & latitude, search, location & google all have additional sync settings, so it seems my phone is constantly connecting & logging my location. God knows what else is connecting..
Didn't have this problem with ICS & I don't have a lot of apps installed, probably less than I did then
Just wondering if anyone else has had this issue? if so it's a dream come true for network providers, but they're going to have a lot of pissed off customers!
Did you check your dropbox auto-sync feature? or any cloud storage that MIGHT be uploading your pics? I did notice the data pull but it was while on Wi-Fi, my data counter shows a lot of activity on wifi but not so much for 3G and that is on IDLE.

if your phone was using that much data you would notice the battery on your phone going down pretty fast as well.
Check if you are syncing Google photos. That was at least our problem.
It could be some Apps or something that is constantly downloading or uploading files. Dropbox auto-sync? Or Google plus instant upload?
Any one using the app in the subject on a Z2? I ask because I do but since getting the Z2 (had a Galaxy S3) the app has stopped tracking distance. I thought at first it was because I hit the home button and send the app to the background so I can use the camera whilst out walking but even if I leave it running and turn off my screen it will track maybe 1 walk out of 10.
I know the app was updated lately so it might be that too hence asking if anyone else uses this combination.
Yep use it loads, recently ran every day for 30 days, endomondo kept the signal / distance for every run.
Much better than my old SGS2

Hi, I have a Samsung Galaxy A3(2017). This is an unattended phone with teamviewer host installed. I want to get to this phone at any times, but I seem to be unable to connect to phone after about 5-6 hours (or one night sleep).
I have tried install an app called HSPA+ tweaked and this fixes the problem, but it eats up my battery really fast. It sends ping request every 5 sec or so.
Is there any other way to keep my 3g/4g from going into sleep? I have tried different programs that stops phone from sleep, but mobile data (3g/4g) will still sleep after 5-6 hours unattended.
Please any help is appreciated.
Thanx

Up.
Noone knows?
Is it possible to make tasker send ping request every other hour?
Any suggestions?

Did you tried connection stabilizer booster?

Seems able to keep a data connetion alive as you need, by using "Keep Alive" and "Reconnector".
Let us know if works.
EDIT: under the settings tab for "Keep Alive" you can also set the timeout for the ping command: by default is set to 5 seconds but you can increase this value.
This app did not work at all. Active keep alive is suppose to work, but it doesn't. It will stop sending ping quite fast. I tried to set it to ping every minute. After 15 minutes it stopped. No error in logs. active reconnect needs root access. I don't have that now. I tried to root, but I almost bricked my device.
