I'm wondering if I have found the cause of the notorious problem with the system server taking up 100% of the CPU at bootup. It seems to correlate with gmail accounts, or exchange accounts syncing at bootup.
To try and figure out what what causing the problem I started with a fresh install of FRX03 (using the latest kernel, 1253) and slowly added back my programs and settings, rebooting as I added things. Only after configuring my gmail account for the first time did I experience the lag. I then changed my gmail to not sync anything and the lag issue went away. I then added my exchange account and the lag issue came back.
After configuring my exchange account to sync on a schedule instead of push mode I've been able to reboot five times with absolutely no lag. I did experience the lag isue one time, but prior to changing my account settings I had to reboot four or fives times just to get the phone working.
For anyone having the issue, please try disabling sync on your exchange and gmail and let me know the results.

I don't use gmail, so i don't sync it. I use hotmail and it syncs everything 15 minutes. I experience lag for about 1 min after booting and after that it works just fine.
Hrm, never heard a theory that it's based on GSync.
I think it's related to netloc - I've heard when GSM guys disable it, the bug all but goes away.
CDMA, unfortunately netloc doesn't work... so it's always off for me, and I definitely experience the bug.
Calling voicemail always clears it up for me.
Some have said opening Google Maps/Places fixes it too, but it doesn't for me - I'm wondering if it's GSM guys that is working for... I'd bet my left kidney.
The calling voicemail trick works for me too, but sometimes the phone is so hosed that my phone dialer crashes and I have to reset. I'll report back the next time I have time to reboot.
And just like that I'm experiencing the problem again.
*facepalm*
Oh well!

netloc = network location?
I cleared the data for network location in application settings and then rebooted and the problem didn't happen so maybe that is it. I keep doing that regularly and see if it continues to work.

For me the Google maps trick works.. takes longer then calling voicemail tho, cause it's a drag to navigate to google maps when everything is in slowmotion, and all I want is fastforward...
Takes a couple of times before it finds my location btw, first few clicks say location not available. But voicemail always does the trick
vmail does the trick
usually when it boots up into No Service, i wait for the 3g signal to come in before dialing. actually put a direct contact just for dialing hahaha

Are you on GSM?
I have this issue again with top showing system_server is constantly consuming around 50% CPU, this coupled with user CPU processes leaves my CPU pegged above 95%. As a result my phone is terribly slow and batt drains fast. I'm on Android stock unrooted 6.01 with a Galaxy note 4.

Hi,
My daily 3g useage today is currently at 64Mb, which is just crazy. I haven't used the internet, you tube, etc; and on checking watchdog 3g pro it indicated that it is my Mail that has received this amount. But, that's impossible, the mail size -when check on laptop through Outlook- is around 3 Mb.
Has anyone got any idea why the mail seems to think it has received 20 times this? Is it the Mail app, or Watchdog 3g pro?
I am running Modaco r11 rom, with most of superfluious components removed.
I don't think it's syncing issue Facebook or any other app. Could another app to receiving this data and it is assigned to Mail.
Just a bit confused. The same thing happened in December, but I think that was related to Advanced Task Killer Froyo, which I uninstalled and haven't had the problem since. But this does seem to happen every two to three months - wierd phantom data.
Cheers
Bumping this as again have had crazy 3g usage - 122mb in 1 day, but same as before, from mail. No way have I used that much, but Orange confirmed it. Only change us that I am.using insertion Rom.
Any ideas why my mail app seems go crazy every do often & download 'ghost' data (idea: is it stuck partially downloading something? In a kind of mobius data loop?)

If I was you I would sort the problem out. Delete the account then add it again. It seems pretty weird though.
Swyped...
default refresh values at peak times are like every 15 mins.... have you changed this?
I personally don't auto sync enabled.... only refreshes when I open
Cheers for the replies.
Hmm, I might try deleting the accounts and reinputting them. But it has happened before, and I seem to be the only one with this problem. Could it have something to do with my email provider (which is also my ISP)? Anyone got any technical knowledge about this type if thing?
The prob with manually refreshing the email is that I'm self employed and out and about alot, so need the email frequency set quite regular so I am not constantly looking at phone - it's set for every 15 mins; that said, I hadn't even set it download whole emails.
Could it be something from rooting? But that should make not difference. Or is there any malware that could be doing this...as you see, grabbing at straws here...
Oh, and the Rom I am using is Insertcoin not insertion (damn that predictive text)

This may have been addressed, but a search didn't reveal anything exactly like this. Please bear in mind that I'm an Android newbie!
I bought the Incredible 2 last Thursday. No rooting, nothing weird, still mostly stock. This morning it's running very slow, screen transitions jerky, etc. and even text based email takes minutes to open. I messed around in settings, and notice that Mail (com.htc.android.mail) is using 48% of my battery, more than twice what the screen is using! I force close, and the phone speeds right up, lag is gone, screen transitions smooth but, minutes later, Mail comes back on line and the phone goes to crap.
I've used more that 1/2 my battery in two hours. I notice that the uptime is 1 hr 58 minutes, and the awake time is 1 hr 44 minutes, so I assume that the mail app is also preventing the phone from sleeping.
Any advise will be greatly appreciated!!
This may sound obvious, but did you try resetting your phone? Turn fastboot off (settings > applications > click fastboot so it is unchecked) then kill mail, and before it has a chance to restart hold the power button, then shut down. The restart option might work, but for things like this I prefer a good old fashioned power down, power up. Anyways, power your phone back on by pushing the power button for two seconds or so. Then see how it goes. This is an error that I have not heard about, but a reset is a universal problem solver. If it doesn't work, tell us what kind of email accounts you have set up (pop, imap, exchange) and how many, and also the settings for checking the mail.
Hopefully the restart will fix it though.

Thanks! My limited Android knowledge told me to try a restart, but I actually didn't know how on the Incredible 2!!
Anyway, the problem went away for a couple hours, then came back!
I use a POP server for my work email, and gmail for personal. I really don't understand this, as nothing has changed since yesterday, but the phone has slowed to a crawl!
Try a third party email app. I don't know of any offhand as I only use gmail on my phone. My gmail account checks my imap account on another host so it's all together, and I can distinguish which account is which on the emails through gmail tags.
Umm I think this will require a factory reset, because you can't uninstall stock mail nor freeze it without root
Sent from my ADR6350 using XDA App
You can temp root, and freeze the stock mail app if that is the way you decide to go. Instructions found here http://forum.xda-developers.com/showthread.php?t=1068544. But that sounds more like something faulty with the software, because like I said, I have never heard of that happening before. I would take it back to Verizon, complain incessantly, and point out that you could have fixed it yourself if the phone had an unlocked bootloader
Do you have them set to check mail constantly, push, or are they on a delay? Can you use imap for work instead of pop? I have four accounts set up on mine, including an exchange, and three imap accounts. The fact that it just started happening leads me to believe something broke in the system, though. A factory reset and re-flash may indeed fix the problem. Also, do you have good 3g coverage most of the day? Check your time without signal under battery status in settings. Click on cell standby and it should give it to you. Or are you using wifi most of the day?
Sorry for the rambling questions, just writing stuff out as I think of it. Trying to narrow down what the problem could be.
Thanks, again.
I'm using the mail settings that the school requires, so can't change them. Currently set only to update when the app is opened.
I generally get good cellular reception at work, and I have wifi as well. I've been trying it with or without wifi today, with no changes. I'll try a reset and see if that helps.
I just mentioned trying another app because I don't see these problems and I do not have the stock mail app configured in any way.

I've had the Inc 1 and now the two. I've always turned off the (auto sync) this would require yyou to open your mail and manually refresh or of you use the sync all widget it works that was as well. Seems to save a ton of battery only drawback being you have to manually check it. Ie. No mail notifications. Just a thought maybe you want to give it a shot.
Thanks, everyone. Using a combination of all your advise, the problem is resolved. I factory reset the phone, then installed only my gmail account. This worked fine all of yesterday, so I finally got off my butt and learned how to use gmail to read and send my work email last night. That seems to be working well. I'm still getting email notifications, but gmail is only using 3% of my battery, as opposed to the 48% that Android mail was using.
Still don't know what caused the trouble, but I'm very pleased with the solution.
Thanks again!!
Email battery problem also on Nexus S
I have also the problem that the standard email is consuming the biggest part of the battery - mostly over 50%. I use an exchange account and a pop email, but both not synchronized automatically (manual sync interval), and I do not use them so often - max. one sync a day...
Anyone an idea how to improve this?

HTC mail has always been a battery drainer for me. I just use the Gmail app.

K-9 Mail
I had also the problem (as mentioned above) with the standard android email programm and a so related short battery life. Since I deleted all email configurations there and installed K-9 mail client instead, battery life improved a lot. Before I could use my phone about 2 days, now it lasts for around 5-6 days...
Hi All,
So NK3 was forced upon me and immediately after the update our corporate exchange active sync email stopped pushing. We use the app called 9 Folders Email. No settings have been changed on our side, we have uninstalled and reinstalled 9 Folders Email. The only way we get our email now is by manually going into the app and refreshing it.
Any ideas?
Thank you
I've got three activesync accounts on my phone and they all work fine. A bit slow to load compared to my old S4. But I get push email for sure.
I also have 3 exchange accounts at the moment and don't have a problem with any of them retrieving mail with "push" option.
However on NK3 75% (not exaggerating) of my battery would get eaten daily just from exchange.. I had other major problems than syncing (almost seemed as if it would never drop the connection after it was done and wouldn't let my phone sleep).
I have since downgraded back to NIE and no longer have any exchange issues, and I am pleased to report that with the same 3 exchange acts on the phone.. exchange service uses like 8-12% battery..
I know not everyone experiences the same results but honestly I think NK3 has big problems.. and exchange is one of them.. at least it was for me.

How many sub folders in your mailbox do you have set to sync? The more you set to sync the greater amount of battery it tends to eat.
I typically set a couple of key folders to sync so those are up to date at all times, the rest update when I open them. Seems to make mine more manageable in terms of battery.
But odd that push seems to stop for some on NK3.

That is interesting, I never thought of that.
my home acct has like 4 folders syncing, my work account has 22 folders syncing, my other exchange has 1 folder syncing, all those in addition to the inbox/trash/sent/etc default folders
I wish I had tried not syncing the folders before I went back to stock, but FWIW I have all 3 accounts on NIE firmware, with all those folders syncing and 1/10th the battery life being used in comparison with NK3 firmware.
but thanks for the advice, I will definitely remember that for the future.
Our IT department had to change our server URL to get push working again. All is fine but as I posted on another cell forum....These are the last devices we will buy from AT&T. We will keep our corporate account with them for now but the remainder of our devices will either be T-Mobile phones OR phones from Global Phones in Miami....NO more locked boot loaders and updates we cannot control..
All my email is pushed to my G3. I've noticed over the past few days that my iPad and my wife's iPad and her Lumia will always get emails first, followed a few minutes later by my G3. Sometimes the emails just don't arrive on the G3 at all (I've waited 20 minutes!). I have no idea what happens to them but they won't appear on the device unless I start the email app manually.
Today I realised that if the email app is running in the background, i.e. appearing in the task switcher (or whatever it's called) it almost certainly, will not receive email. If I manually shut the app from the switcher, the emails will arrive immediately and continue to arrive as long as the email app is not open in the background!
I've restored the phone to factory settings and it still does it, albeit intermittently. I've called LG support and they don't seem to have a clue and suggest that it's an android problem as opposed to a LG problem. No surprise there!
Can anyone help please?
Hi,
I also have push email configured in my phone, and i haven't noted the behavior you comment.
Do you have any battery saver installed? Or any restriction to the background data?
Regards
Sent from my phone
No battery saver, background data on as normal. Wifi is on also.
Just tried to ping the device and no pings coming back. Looks like the wifi is going to sleep despite it being set to stay awake..
This is really strange!
Can anyone help please? My G3 is the very last device in the house to get email and many times, it's just not getting them at all.
It seems to just go to sleep and not receive pushed email!
Is android just slow at getting email?
