Hello,
I haven't been using my phone today, this is just with very light browsing and leaving it idle.
NetCounter reports 700MB+ data usage already for "Today". How can this be? In the past 7 days it says I've used 5GB. What is stealing all this bandwidth?
I haven't installed many applications, can you guys think of anything that comes on the phone by default that would use this much data?
Something appears to be constantly syncing. Do you have Exchange installed? If so try removing it and adding it back.
I just captured a tcpdump of the network traffic and will load it up in wireshark to see if I can identify anything out of the ordinary.
Alright,
It's the facebook client. It's busy syncing all my friend's pictures and recent uploads :-/

wow, that's a lot of updating. I'm going to take a stab in the dark and say your battery life sucked lol
Glad you got it figured out, and that I don't have facebook set up.
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.

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?

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...
guys, I've recently noticed that mail_service (from exchange)wakelock drains my battery pretty badly, I've reset the account a few days back and enjoyed quite a bit of good battery life (like 1-2 hrs for 1%, with 3G/data on and auto sync off) for two days,but today the bug came back. I wonder any of you experience this?
There has been reports of battery drain and the Android OS not going to deep sleep properly. However, there's to many factors to take into account.
Some claim that opening and closing the camera app has something to do with it. (CMOS sensor is kept open and active)

my Android OS was at 30some%, the betterbatterystats showed mail_service contributed to over 50mins wakelocks while I set manual sync. I am afraid it's another bug that android has.
exchange sucks when it comes to battery life, but I think it's more a protocol thing than an app thing. I did battery tests ages ago on my nexus one, and found exchange sucked up more battery/h than gmail/gtalk/facebook/+++ (basically everything else + phone idle) did combined.
Note that if you dont have exchange on push sync some exchange servers will require a full refresh when you connect. So it'll suck up more battery to sync every hour than having push notifications on. (Although exchange push requires a continously connected encrypted session... which isn't great for battery life either).

I've been using exchange since I got my Desire and GS2, but neither one had problem with exchange draining battery (which I didn't find it from betterbatterystats), and even for Galaxy Nexus, this bug is on and off, I hope there's a solution for that

It never showed up in the battery stats for anything. But if I disabled exchange and left it overnight I'd have WAY better battery/h than I did if I left it on.

I removed the account, just to be certain it wasn't doing anything. When I added the exchange account I noticed a quite bad drop in battery time, even though it never showed anywhere. So I tested it overnight tons of times with different settings. And the thing that helped me improve my battery time more than anything else was removing exchange.

well, that sucks, i need my exchange to get through my job, when exchange is behaving well, i got quite good battery life with 1% drop with 1-2hrs with no tweak (stock 4.0.2), now when exchange bug kicks in 1% would drop in around 15min. i can believe Google can still let it happen when we are already in its 4.0
I had this problem using Enhanced Email, and was able to resolve it by disabling calendar sync for the exchange account. As I understand Enhanced Email to be pretty similar to the stock email application, perhaps you might give that a try and see if it improves the situation.
I suspect the battery usage and best settings depend heavily on exchange server types as well. So do your own testing on this

I've tried Enhanced Email and seems it doesn't support calendar sync fot 4.0 just yet. and i really do need calendar sync for my job.
actually, i also bought Touchdown, but too bad that it can't be integrated into phone's calendar, and the calendar viewing is suck for TD. (i really got spoiled by Calendar Pad / Jorte which can display individual events under month view.)

i think so too, but i think if i set manual sync the app shouldn't have that much of wake locks which keep my phone awake which drains battery.
I had my exchange account set to only sync email. I also set the check frequency to manual... the exchange service would still suck up a ton of battery. Every few hours I would receive a notification of new email for my exchange account. WTF? Why was it syncing in the background when I had sync set to manual..?

Then I downloaded touchdown and haven't gone back to the stock android email client.

Sorry I don't understand ur first part? So it had gone to normal after a few hours of syncing you mean?
Done more testing yesterday, after a 12hr working day (no emailing on phone but few calendars added/editted,all time 3G & data on ) , the exchange caused around 500 partial wakelocks (spent around 10min in total) reported by betterbatterystats, causing my phone to drop 1% in around 30min which I've undervolted using JameBond 1.2-307.
Yet, when I got home, I switched to my home Wi-Fi and found that the wakelocks were much less and my battery dropped 1% in around 1.5 to 2hr.
Don't know if the network status from 3G triggered the exchange to drain power from wakelocking.

If your undervolted then your battery readout is incorrect anyway. Your battery meter isn't displaying actual battery capacity, it's estimating it based on a scale of power consumption @ X mhz of processor speed within an actual timeframe.
When you undervolt, there's no reference point. Your battery display is somewhat useless. It's why often times the last 10% @ idle seems to last forever.
I have high battery usage from Exchange. It's been a concern of mine for some time. Glad to see others noticing the same thing.

I am connected to two different Exchange accounts, one 2007 server and one 2010 server. Both set to automatic push. Battery life has been excellent with this phone and getting better. Yesterday, with several phone calls, emails, etc. I clocked in at 1 day 7 hours before I hit the 14% warning threshold.
Hello All
I have a GNex "yakju" updated to Android 4.2.1 (stock, non-rooted). After the update, I have seen that Android OS started taking a big chunk out of my mobile data plan, around 40-50 MB per day. Previously, I'd hardly see any usage from this process.
I have started to investigate this behavior by using tPacketCapture. So far I've managed to see a lot of traffic to google servers (173.194.35.163) and the hourly exchange server sync, but it's encrypted and I don't know how to extract the TLS key from the phone (not sure if it's possible). In one hour there were about 3.3 MB of data transferred (I'm running on 2G to conserve battery), with no background applications.
Right now I'm rerunning the test with Auto Sync Data off, to see if it's not some malware, but it's highly unlikely (almost all my apps are from the play store) and will rerun the test with Backup to Google turned off.
Anyone got any insight on this? I could post the pcap file somewhere (I've scanned it and I'm pretty sure there's no unencrypted personal information in there), but I don't know if it helps.
P.S.: I've seen a lot of similar threads on here but they relate to other phones, and the majority of suppositions were hinting towards the bloatware of the stock ROMs
Turning off sync should do the trick.
But I do hope to hear from you.
So I turned off sync and it seems to do the trick (only ~200KB in one hour and all traffic was from a facebook app that does not obey sync rules - flipster). I don't like having sync off since it means no more notifications for new e-mails, facebook or contacts, and also these services were turned on before the 4.2.1 update.
I'm trying a new run with sync on but disabling everything that I don't care for (photos, google+, backup, currents, notes). Looks good for now (~56KB in 10 minutes). I'll see what happens.
Another odd thing I saw in the initial run - data came in chunks of packets roughly 7 seconds in between (a lot of packets, including SSL handshake, at 300 seconds, then a few packets, then a lot of packets again at 307 seconds, then at 314 etc.).
Monitoring, will post results ASAP

Maybe you've already done this but have you tried going into the sync settings for you google account to see if any of the services are failing to sync? For me the browser sync had been continuously failed for 2 weeks before i realized it.
I did have some issues with calendar and Google Photos (I think) not syncing, but I thought it was because I cleared the cache of Google Framework Services in an attempt to get the update to 4.2.1 earlier. Not sure if it helps, since I don't remember seeing any sync errors these days. I've stopped Browser sync now, I'll see how my data usage changes.

I faced the same problem, issue was somewhat with auto backup of data, sync of app data & people details in google account,
BUT the main culprit in my case was uTorrent application.
Even though there was no torrent added to it, i didn't even opened it,
it was using 1GB data daily on WiFi and in data usage it was coming under Android OS usage. I uninstalled it, everything went back to normal.
So try to look for such apps which eat up your data in background, it may not be an error of android OS as such.
Hope this helps, Press THANKS if it did help you
Enjoy
