I discussed this here: http://forum.xda-developers.com/showthread.php?t=713392&page=7
If you are an Exchange Push user on Froyo experiencing significant battery drain and frequent if not constant 3G connection I found that you must turn Push Off and then back On.
This resolved the rapid battery drain and constant 3G connection issue I experienced. Just for your information.
I think this was a result of the Update rather than Fresh Install, it accompanied many settings I had to re-do.
Exchange - I take it back. Resetting exchange did not fix my issue. On Eclair, the push email would not keep the network always connected. On Froyo exchange push is running the CPU at 20% constantly and keeping 3G connection going.
Not sure how to stop that, but it only occurs when I turn on Push. And this definitely was not here before. Thanks to this my battery goes from Full to gone in a few hours. I have since turned off push email.

This happened periodically on Eclair for me as well - just "clear data" for the email app and set the exchange server up again. Seems to fix it when it creeps up from time to time.
On a side note battery life w/push on Froyo has been better so far. With 2 push accounts I am now losing < 1% / hr when sitting idle (overnight). On Eclair it was just shy of 2% so this was a nice improvement.
I have now done a full factory restore and reinput the Exchange Push account information.
It is still at 17% CPU usage and keeps the 3G connection on constantly.
This simply did not happen before, and is draining my battery rapidly.
Update:
As if to prove my point again, once I set the email from Push to Pull every 15 minutes the CPU load dropped down to 0% and the 3G connection stopped cycling. Not sure why this is happening. Is anyone else noticing that Push keeps 3G constantly active and phone runs really hot?
SO FRUSTRATED!
Please someone else tell me they are experiencing this with Froyo Exchange.
I am not able to stop exchange from cycling 3G and Email runs a huge CPU percentage and the phone heats up continually until the battery dies.
Is anyone else on exchange seeing this problem????
Hello All -
I know I continue to post on this but I am really hoping some of you that are smarter than me can help me out.
On 2.1 - Exchange would get can email, my 3G arrows would cycle, the email would show up. That is all.
On 2.2 - Exchange does not get email, 3G arrows ALWAYS cycle and the cpu is running constantly. The phone last night was over 100 degrees.
To experiment, I installed Touchdown. Exchange works perfectly. No 3G or CPU issues. It does not constantly sync.
A few items I noticed:
1) SyncManager for Email is the culprit and causing the problems
2) My corporate email is ActiveSync or MS Exchange 2007
3) I have read elsewhere that this is Exchange constantly trying to check the server and it gets stuck in a loop.
Please friends, this is going to cause me to have to give up my phone. I dont want that. I want my native Exchange to work. Any ideas at all?
I'm having another issue (and it's being tracked on android official support board)..
Whenever I use PUSH for exchange, it works fine. Yeah it keeps connection alive, but doesn't really use the battery that much.
However, if I switch from PUSH to some interval (5, 10 minutes, etc), sync manager gets stuck. It'll eat up 50% CPU CONSTANTLY until battery is dead. Switching back to PUSH fixes it immediately.
Google assigned an engineer to this problem, but nothing yet.

Do you have the link to the tracking of this? I think this is the same thing happening to me, SyncManager getting stuck and just running up the process until the phone dies.

Hmm.. strange, I can't find it now.. Last time I checked it, first 2.2 was released.
Maybe it's fixed and closed now? I've enabled 10-minute sync in my exchange, I'll see if it still gets stuck in FRF82.
I wonder if any smart network Dev out there can tell us why SyncManager is getting stuck trying to work with our Exchange Servers?
Ok Friends Help me out with this.
I installed OS Monitor.
With my exchange running it says:
"07/01/2010 13:07:27 [DEBUG]
NativeCrypto915860

It repeats the OpenSSL ever second or less and the GC every 6 seconds. It never stops.

Bump....installed FRF91, no fix.
Anyone know what is going on with this? Is this a server or OS issue? Could it be a bad install somewhere?

Update: almost all day on 10-minute update with Exchange (and I barely have any reception here, goes from 0 bars to 2 bars and back).. sync is NOT using up CPU at all, and mail is working fine. Looks like it's fixed?

After much hassle I think my issue now has to do with my IT having self-signed certificates rather than purchasing them. This means they would have to update it to work with whatever Froyo did in exchange security. I think this is why it works initially then goes into a loop of OpenSSL attempts.
This is my only guessing from half-truths and limited understanding of the series of tubes.
I would really appreciate anyone out that understands this stuff chiming in on what is going on?
http://code.google.com/p/android/issues/detail?id=9455
got a google code issue going in case anyone else runs up against this openssl infinite loop.
I am having both issues. When I use push, the phone stays warm and the battery drains in a few hours. If I switch from push to poll, no improvement - but if I reboot with poll setting, it works fine.
My company uses Active Sync with Exchange 2003 and I doubt we would use self-signed certs.
By the way I am running 2.2 on a G1 with Cyanogen ROM.
I have a funny issue with my exchange. When i get a new mail, i get a notification on my N1. But even after i have read that email on my PC.The notification doesnt go away .... and when i check my phone after some time i think i have recieved a new email but its only notification of old one .... is there a workaround for that guys ?
Cheers
Nice thread hijack
I have an Exchange 2010 server setup with a non-trusted cert from CAcert.org and don't have that issue using Push on Froyo.
I assume you enabled the option "Accept all SSL certificates" when configuring the account?
I did in fact "accept all" and I have been working with many google developers as of last week to figure out what is going on.
It is not actually IT, it seems it is an OS issue as more and more people are seeing this issue come up.
P.S. to the notification comment above, that is normal. dont hijack my thread.
Hi,
I bought a Samsung Galaxy S about a month ago, and have been having odd problems with it since the off. Has anyone else had these sort of symptoms:
1. I occasionally lose my data connection - the icon disappears from the top of the screen and whilst I can still make and recieve calls and text messages, I cannot download anything in any app. The only way I've found to get my data connection back is to reset the phone. This happens maybe a couple of times a week.
2. My WiFi seems to suffer from a similar problem. I can be browsing the web on Wifi, then suddenly I'll not be able to download anything anymore. The wifi icon is still visible, but I'll basically be unable to download anything until I switch the wifi off and back on again. Then, it starts working as normal again.
In both these above scenarios, I think I've narrowed it down to primarily happening after I use the Android Market, but it's difficult to tell as it's very intermittent.
3. A couple of times since getting the phone, I've been unable to make or receive any calls. Even switching the phone off and back on didn't help - my signal bar was showing I had a signal and my data connection was still active. Couldn't tell if this was a network problem or not though as there weren't any people nearby on the same network as me. After a while, it started working normally again.
4. The email client randomly lost all of my email settings. One day I was receiving all my emails, the next day I had no email accounts set up at all.
5. I installed Sensor Dump and Phone Explorer to see what data was coming in from the sensors, and have noticed that the light sensor never sends any data. Is this normal?
I also have the usual slow-down issues, etc, but the above have got me stumped as I can't find anyone else reporting the same issues. When I first got the phone, I went crazy installing a load of Android apps, so initially I blamed the software I'd installed. After a reset and being a bit more selective with the apps I install and use, I'm still getting the same issues. I just can't pin down whether this is a faulty phone that I should return, or if there are software issues either relating to the way I'm using the phone or just with bugs in the firmware.
Has anyone else had anything like the above happen with their Galaxy S?
Thanks,
Chris.
I've experienced no.2 several times, wifi just stopping all data traffic. Not found out what causes it though.
As for the other problems, I haven't experienced any of those. Do you use automatic brightness on the display? If not, problem no. 5 might be caused by the sensor being turned off.
thanks for the reply - at least I'm not completely alone!
I have the automatic brightness turned on - which is why it seems odd. To be honest, I've never actually see the auto brightness do anything. It always seems to be the same brightness to me.
Cheers,
Chris.
Strange Problem
Hi,
I've experienced no.4 some times. My inbox did not show some older mails.

I think it might be normal that older mails disappear from the inbox after some time? My problem was that everything went. I had three email accounts set up, all downloading emails every hour. Then, one day I went into the email app and there were no accounts at all! I had to set it all up from scratch again.
I hear there are better email apps available for Android, so I'll probably switch to one of those soon.

Hi,
I bought a Galaxy S on Orange UK in July. I'm having the same problem as 1. quite consistenly now.
I thought it might be related to the green power battery saver app I had installed, but i've removed this and still having the problem.
I'm using the phone in several central London locations so I think it's unlikely to be a problem with the data network.
Any suggestion would be welcome since I'm often without data.
Thanks
Nik
ive 1 and 3 but very rarely so far
rebooting fixes it for me
running froyo jp3
for email i use K9, it's almost the same as the integrated mail, only much better (PUSH imap)

I'm actually getting this happen a lot now. It seems to be getting worse, which makes me think it might be a hardware fault. I generally lose my data connection once or twice a day minimum, but some days the phone is virtually unusable.
I have found that it's more likely to happen after using Wi-Fi, so my other thought is that when coming out of Wireless mode, the phone may not switch the normal 3G/HSDPA data connection back on. Most of the time I can fix this by putting the phone into flight mode and then back out, but sometimes it needs a complete reset.
The other problem I've noted with the data connection is that sometimes it seems to rapidly switch between HSDPA and 3G - the data icon at the top of the screen keeps going from '3G' to 'H' then back again. I guess it has something to do with signal quality but it only seems to happen when the phone is showing a good signal strength (four bars). The problem I've found when this happens is that it virtually locks up any ongoing data transfers, making it impossible to download a webpage or check my emails. Strangely the only way I've really found to stop this happening is to move somewhere where my signal strength is weaker, such as indoors, which then seems to make the phone stop attempting to use HSDPA. I can't find a way to switch off HSDPA from within the phone's settings while leaving 3G on.
I really am now finding that using this phone is an increasingly frustrating experience. I've found even more weird faults, such as sometimes my text conversations show the wrong people's names up against them, and then my replies go to the wrong people. It's like an insane, shiny mess of a phone!

I am indeed experiencing same problems above..it just drive me crazy with a need of complete reset everyday..
turning on n off flight mode won't change anything..
I really hope someone can bring a miracle to solve this problem..
I'm on XXJPC
setting the APN parameter(Setting-->Wireless and network-->Mobile Networks-->Access Point Names-->New APN) to 2G only seems to solve the 'lost data connection' problem..
I am connected 24/7 now..
Give a try guys!
I had a problem with the stock EMail app.
It stuck at 100% CPU load, the phones back was hot and the battery lost ~70% in half an hour.
I can't understand how this could happen, the app is set to check both my EMail accounts every hour and there has been nothing out of the ordinary (no big attachements or so on).
Anyone else had this problem? Any solutions? Should I use a 3rd party app for EMails?
the same problem

It happened to me three days ago Using OS Monitor, I only showed 34% usage, but this time, Android System Monitor acknowledged 100% usage, but was unable to account for where it was being used. where did you see it stucks at 100 % , it sometimes shows wrong , ;
you can also check ur email mobile or 3rd party app or reboot ur device you can also fallow these steps , maybe it helps you.
go into "Settings...Voice input and output", and, if the Eyes Free TTS engine available, the default TTS is not set and check the box to have the native TTS as the default, and checked the box for "Always use my settings".
I saw it in the Samsung Task Manager. I think it showed correct because also the phone's back became very hot.
But, fortunately, this never happened again until now. The battery life is terrible after all, but the EMail app seems to be fine
I have a similar problem if I'm not using the standard Samsung keyboard.
It's a bit of a pain in the arse as I have to remember to swap keyboards if I decide I need to reply to something. If I forget the phone locks up and the battery drains very quickly.
I've seen other posts with same problem. Wouldn't be so awkward if the standard keyboard wasn't so useless.
I binned the stock samsung email app, and use the 2.3.4 vanilla email app
I'm having major problems with the Mail app too - consistently high CPU usage, short battery life, back of phone warm to touch and Mail showing as the top battery hog (& CPU hog in Watchdog). Not impressed!
High CPU usage and email app gets stuck
I have the same issue. When I am in the email app it just gets stuck. This is crazy. I switched out from a HTC EVO 4g to Samsung Galaxy so I could have more ROM. I hope I don't regret it. Tell me if you find a solution.
I had the same issue on my SGS II and now my Note. I finally figured out it started after I installed Viber. I uninstalled Viber and the issue went away.
Does anyone else with this issue have Viber installed?
I had this problem only once yesterday - picked up my phone to answer a call and it was very hot. I can't think it was a co-incidence that earlier that day I had enabled Contacts sync with Exchange. Whatever the issue was it has gone away by itself. The only other factor worth mentioning is I was in a supermarket with Free WiFi - but it only works after you click through their homepage. Previously I seen this cause background apps using data to constantly stall due to the HTTP redirect they encounter.
Hi guys, I have setup my corporate Exchange mailbox using the built in application.
However, it works VERY poorly (settings set to Push) - sometimes the widget (or alerts for that matter) wont display new mail for HOURS! Until I manually go into the Mail application, and a minute later suddenly I get all the emails, and 4 emails I've been trying to 'share' (Notes) have been all sent at once.
Any idea how to fix this? or what to use instead?
On my old Dell Streak, using the default program, I had instant alerts on emails! sometimes even before Outlook had a popup!
this is annoying to no end..
I'm not sure if you're organization sets device security, but mine required a passcode to be set on my device if I used my Exchange account. For whatever reason I was still able to use the pattern lock but I noticed the same delays that you did. On a whim I set it to a numeric lock and all of a sudden my mail decided to push properly.

ok well, I tried this - 10 mins ago someone sent email (I see it on outlook already) - yet nothing on the Note (I switched to numeric lock hours ago), so must be something else... any ideas?
wifi is connected, and gmail is getting updates without issues.
I have this problem, too, and I've seen several others post about it as well. It's quite frustrating. Sometimes it works instantly and sometimes it'll go a couple hours without sending/receiving. Some people think it's a push bug and say changing to polling fixes it, but it didn't for me. I set it to 15 minutes and I still get the same problem with delays. It's really frustrating. I'm going to see if it's an app issue by installing another email client such as K9 or Touchdown.
Also, I wonder if it's a connectivity problem; I've been having weird issues; I work from home a lot so I'm here a lot in my wifi, and it seems sometimes my phone won't use the cellular network. I turn my phone off, it goes into deep sleep and turns wifi off, then I won't get any emails until something else wakes my phone, turning wifi back on. Like the email client can't or won't wake the phone when needed. I'm going to start a post about this tomorrow.

My wifi also disconnects sometimes if the phone is idle I don't know why.
That happens at home, it does not switch to 3G as I don't have any 3G plan atm at all (and its disabled in settings anyway).
However the mail push issue is prevalent even when I use the phone and its active - mails still don't arrive! even if I click refresh on the widget itself, no new mails until I launch the Mail application!
Ok well, this has gotten worse.
My limit is when I show up for a meeting only to find out 15 mins ago a postpone email was sent.
I've mailed Samsung support, hopefully will get an answer to resolve the issue - will update when I hear something back.
Anyone else experiences the same problem? please post here...
Also anyone who solved it
I had the same issue as well,So i deleted my Exchange account started all over again from scratch,on the set up i chose all the options I needed,now it works as it should,so what I have noticed:
1-After the setup is complete,if you go to the Account Settings and start to fiddle with the settings that seems to upset the push funtion ,except changing the notification sound didnt do any harm.
2-When I assign my custom Notification tone it also seems to upset the Push funtionality(but I am not 100% sure of this one yet.)
Alright. My phone is having a huge problem syncing. First I noticed it with Gmail. I can tell how instant I am getting emails because I am sitting here at work on my PC. I can send an email from where ever (in this case my outlook work address), send it...see the email pop up on my screen in the Gmail internet tab. Here is the thing. It takes anywhere from 1-20 mins for the email to finally get to my phone. It is SO random. Sometimes if I pick my phone up and turn the screen on, it pushes through alittle faster. I have tried everything (I think) the last two days. Obviously all my settings are correct. AutoSync, the Sync settings in the gmail itself.
To see if it was just gmail, I put my work email on the phone to see how that works. It's EXACTLY the same. Sporadic syncing. I then tried cloudmagic email app which people rave about. Same thing.
What gives? I've about had it with this phone. I even tried a factory reset this morning. Still have the issue. I'm thinking of taking the phone back honestly. Could this be a hardware thing to do with connection? I've tried all of this with strong wifi on, and with perfect 4G signal. Any ideas would be GREATLY appreciated.
Thanks
Nobody here has ANY idea what could be going on with my phone? I thought I fixed it and had it narrowed down to the WiFi st work but I just tried it again and it took 6 minutes for it to show up on my phone. If the phone is awake, it seems to be faster. Does this sound like it could be a hardware issue? Should I take this phone back? I already did a factory reset ect. Someone please help!!
