Hi All,
I have been experiencing poor battery life with my N1 - until I stumbled across the issue.
Now I am trying to figure out how to fix the issue.
Basically; I have 3 email accounts setup (1 push to corporate exchange and 2 pop3 accounts).
What I have noticed is that randomly the email accounts will fail to receive emails and when going into the email app the loading circle (or whatever it is called) just spins and spins indefintely. This obviously results in usage of the phone (i.e. not sleeping) and the phone heats up and battery goes down v.quickly.
Now, I know I have sufficient network coverage as I am able to surf and use other network required programs - so it does not appear to be due to not being able to get a data connection.
Has anyone come across this issue before?
yeah I have this issue too... its pretty annoying.
Ok thats comforting...sort of. Atleast it is not specific to me then. Sounds like a bug?
What do you do about it?
i have a similar issue...my pop mail...just wont receive email...it looks, and stops...but no email...its not draining my batt btw
Slightly different in that mine looks and looks and looks and just keeps doing so - until it has drained by battery as best it can. Most of the time I have realised as the phone gets hot due to not sleeping. So I can kill it off.
Quite annoying however. As email is fundamental program with these types of phones.
Is there somewhere on Googles site where we I can inform them of this issue?
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
Freeing Open SSL session"
07/01/2010 13:07:51 [DEBUG]
dalvikvm915860
GC_FOR_MALLOC freed 7078 objects / 511984
bytes in 71ms
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 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.)
So I thought it was a google thing since my hangouts/talk msgs and gmail email have been recently slow or nonexistant but I've noticed it with other apps. This has been going on for a week or so. IM repies, email, score notifications often don't show until I open the app or refresh(gmail). Thing is...it's very random. Sometimes they all seem to be on time. Other times, not. It's very random.
They can show in my notification bar on time, minutes late or hours late and, again, sometimes not until I open the app. I've noticed it much more this weekend when I've mostly been on wifi but emails and such will show on my laptop(running off same wifi) yet may or may not push to the phone as stated previously.
Any ideas?
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!!
