[Q] [BUG] E-mail app keeps phone awake all the time - Nexus S Q&A, Help & Troubleshooting

Hi folks, been lurking around for quite some time now but after I recently acquired a Nexus S, thought I'd jump in in some of the discussions here.
I wanted to report what I think is a bug with the e-mail app (when using Exchange service). My battery is drains pretty quickly and when I look into the battery chart, E-mail is by far the greatest contributor (over 50% depending on how long it stays).
You quickly notice why, because the "Awake" line just keeps toggled on all the time (caused by the E-mail app).
I've tried switching from Auto(Push) to Manual and with Intervals, but the same thing happens. One thing I noticed in the Manual mode though, is that if I have only read e-mails, then it does not stay awake! But having one unread e-mail just puts it back to "battery draining mode" all the time.
Anyone experiencing similar issue? It's really annoying and could not find a workaround (except marking read e-mails all the time!).
I've logged this issue in Google Code as well, it's issue #14590. I have the stock Android 2.3.2 (rooted but not with an unlocked bootloader).
Thanks,

Update: now even with just read messages, the phone keeps awake all the time. It's just so frustrating...

TP2 and Imagio Battery Useage

Okay, I have an Imagio (please don't judge me ) and like many of you TP2 owners, the only real complaint I have about the phone is the battery life.
For me, I rely heavily on the device as a phone first (no big surprise, right?), email second, and then text and internet. Based on how I use my phone, I think the biggest contributor to my quick battery drain is the fact I have to leave my data connection 'on' to auto send/receive email.
I'm interested to know if there's a tweak or something out there that would allow me to leave my data 'off', automatically turn it 'on' to send/receive email at my specified interval, and then turn it 'off' again once completed. I know I could do that manually but was curious if there's something out there that could run in the background.
Also, thinking about it, has anyone looked into changing the weather tab uppdate time? I'm also wondering if the weather sync feature is sucking battery power?
Ok, my TP2 with Telus I have on data all the time, with push email (so more frequently goes active) and have no problems at all with battery usage. I can go several days between charges, but don't because I plug my phone in every night anyway.
How much talk time do you have on the phone on an average day? How many emails do you recieve? Is it exchange based on POP/IMAP?
You can easily set up the email sync itself to be manual, i.e. open your email app and click on send/recv - this way it won't hop on itself to grab emails all the time which will help with your battery life, but not really by much.
Similarly just set the weather application not to update automatically.
Keep in mind that a single phone call (on average) lasts about 3 minutes, a single data session lasts only a few seconds.
But even if you still want it to send/recv at a specified interval then when the connection is dormant (i.e. in between scheduled send/recv) it's not really taking any more power than if it was "offline" - this is just a state that both ends know, not an always-active transmit/receive when there is no actual data.
If you really need more battery life then just wait a few seconds when you check your email or the weather for it to go online and grab the data on demand.
Thanks for the reply Telek. Since I've had the phone, my talk time per day has been pretty low, relatively speaking. I seem to notice the drain after the phone's been sitting idle. I charge daily but if I didn't, I'm guessing I wouldn't come near several days on a single one.
I do get poor reception while I'm in my house and I'm thinking that might have something to do with it. What you wrote about the data connection while inactive makes a lot of sense - I should probably be looking elsewhere.
Also, my phone is set to CDMA only in case any viewers are thinking of asking the question.
Well poorer reception will hurt battery life, but only while the phone is active. CDMA signals all have to reach the tower at the same strength (IIRC) so if a phone has poorer reception it will have to up it's broadcast power.
How many emails are you getting daily? Is it feasible to just go to "on demand" and manually do a send/recv to see if that helps your battery life?
It's possible that the phone isn't going into sleep mode, or times out at a much longer interval than normal. Perhaps try going into the power management page and shrinking the timeouts?
Not sure what else to suggest - maybe you just have a bad battery?
I am in the same boat here. Although I use pop and don't get that much email. I use it as a phone, text, then data. Just through a days use, sometimes not making a phone call at all my battery will be near death. I HAVE to charge it daily. I have a car charger, charger at work, and 2 chargers at home so I always can charge so it isn't that big of a deal for me. My signal strength is normally above 70% through my house and work.
I am ready to try out a new rom to see if that makes a difference.
PS not trying to thread steal but throwing out some info that might help.
I have to charge my TP2 like 3 times a day. Between Twitter, email, and reading on the net it goes pretty fast.
My battery life isnt too good either...I have email set to check every 2 hours. If i browse the net for about 15 minutes I lose a notch in battery life. I have to charge every night too!!
I got the 2100 extended battery in the mail today, im going to try it out and see how it does...if it's not a big improvement then im sending it back...the extended battery cover is ugly and slightly bulky so I dont like that to well...
Has anyone fooled around with the power management settings in ATC? If so, any notable changes worht exploring?
Well for my usage on a Sprint Touch Pro 2, I get good battery life. I make maybe 10 calls a day but each call is less than 2 minutes.
I surf the web maybe an hour a day and send + receive maybe 75-100 texts a day. I dont check my email to often.
Maybe 3 times a day I press Send/Receive but after I finish my stuff, I go to Communications and turn off my Data Connection.
At the end of the day I have about 60%. Although I have my backlight set at 30%. Others like it halfway and others fully set.
30% is ok for me indoors but once outside I turn it up to 80% if I really need too but then set it back to 30% once indoors.
Some solutions to Imagio battery drain
My 1st Imagio had no problem with battery, but the "end" key broke so I had a replacement sent. The replacement had nicks on screen and major battery drain, with overnight charge, by 3:00pm I had 5% left. So I sent for 2nd replacement. Same problem with the battery, fully drained by midday. Frustrated, I went to Verizon and requested replacement battery. All seemed well at first. Then, the new battery began to drain. I started eliminating programs running and now, at 10:00pm, I still have 72%, I talked, texted, sent pic mssg, got email, updated weather...etc. This is what I changed.
I turned the phone to CDMA only.
I changed input back to default HTC qwerty (I had sip change to swype)
I set email to check once a day, but I hit send/receive periodically
I set weather to check once a day.
Sorry, but I also uninstalled "codyppc performance booster"
I reinabled Auto Divice lock. (this seemed to help save battery by locking)
I am running spb mobile shell 3.5 and WM 6.5 interface. Whenever I run the HTC Touchflo3D it seems to drain more battery, along with suck up memory.
I check running applications often, reset a couple times a day. I am having an issue with my spb time alarm going off in the morning though. I will try something tonight to eliminate that as the culprit. Overall, I think anything set to run regularly will drain the battery. With these fixes, now I LOVE THIS PHONE. I have all my programs on it, lots of program and storage memory left, (more than I had out of the box) tweaked just the way I like. Hope this helps someone.
Please don't forget Clean Ram(search xda) , helped me alot.

[Q] WiFi Sleep causing Widget Update issues

Hi, just a quick post to ask anyone who's using the "WiFi off when screen off" setting whether they're finding that some of their widgets don't update properly after the transformer is woken up?
Behavior I had seen (prior to the 0213 update?) was that you could use this mode.. when you first wake your TF you'd see "No internet connection" for a few moments, with the wifi kicking in shortly after, followed by your widgets all updating as required.. (assuming their update schedule might have meant they attempted to update while the wifi was asleep and failing naturally)..
..well now, I'm seeing that they aren't all updating in the same situation now.. most notably the Asus email client and widget (connecting to Gmail via exchange settings)
I'd rather use this WiFi mode if possible, because as far as I've seen it really does make a difference to standby battery life (say, when its not being used over night) compared to leaving WiFi always on or remembering to switch on Airplane mode (which I'm not sure wouldn't cause the same problems)
Any thoughts gratefully appreciated
The widgets that require Wifi? Unless the widget has this option that makes it update automatically when you turn screen on, it will be refreshing at a timed interval (depends on widget). So it isn't a bug.
Yeah, I know that but waited for the refresh interval to pass and still no update. I also tried to get the email app and widget to update by marking one of my emails as Unread on another device (and waiting for the change to propagate) the exchange 'push' email should've forced my email to update (the point of push email?) but it didn't.. I also went into the email app and manually selected update which just resulted in the progress circle spinning for minutes on end before I gave up and rebooted the TF - on restarting, everything updated just fine...
I should add that setting WiFi to never sleep meant that push email and everything worked fine (e.g. setting emails to unread and watching the push email work as expected)
ok, well on my TF at least can pretty much confirm that the Asus email app crashes and must be forced to stop if you try and use if after waking the tablet up - this is using the 'wifi off when screen off' mode... anyone else noticed this?
Well, ended up logging a support ticket with Asus.. apparently the 3.1 update coming shortly fixes issue with WiFi Off when screen off causing problems with certain apps.
Guess we shall just have to see, here's hoping
..Another day another post (for anyone who's reading).. Looks like Asus were as good as their word, and after the 3.1 FOTA their app (and widget) now refreshes properly after the device is woken from standby (using "WiFi off when Screen off" to preserve battery life)
The Gmail widget is gone for many of us and until a fix arrives, at least this will work now

[Q] "Dialer" has started to eat my battery?! What to do?

HTC Desire S, not rooted. Original ROM.
Yesterday I noticed my battery starting to plummet FAST.
As in 1% every two minutes I was on wifi.
It had been doing very well with no real issues.
I had installed a new keyboard, which I disabled thinking it might have been that. No go. Still plummeting.
Just under display at 64% was Dialer at 18% This is new, I'd only ever seen it if I'd been on the phone a long time. This time is was eating up the % when I'd never even made a call.
I killed every task I could see trying to find the cause. Nothing.
Then, out of luck, I noticed the sync icon flash for a micro second on the notification bar. It was doing this every 30 seconds.
I Looked around in synching and disabled everything. The icon stopped.
I enabled background data, but turned off auto sync. The icon remained off.
Then on the google part of the sync menu I clicked Google reader, Gmail, Calendar and Contacts .... Contacts came up with a little red (!) and a note saying Sync is currently experiencing problems, try again later.
no problems, I disabled it.
Now, on full charge I left the phone for 2 hours. Only thing on was Wifi. And, again "Dialer" is popping up under Display as being the top usage of battery?!!
I've not touched it! And the phone is back to loosing 1% every 2/4 minutes again.
Within "Dialer" in the About, battery etc I see Simtoolkit, Phone, Dialler storage as included packages.
That's all I know.
Can anyone offer a solution or idea as to what and why "dialer" is eating my battery like this?
Hello
I'm afraid that I can't explain but can say I've seen the same with Dialer before.
You did the right thing, in manually adjusting the syncing, that eats battery when phone should be idle....
I'd suggest that you read the sticky [GUIDE] Update 28/06/11: HTC Desire S Guide (V1.03) For Newcomers to Android which shold give you some pointers on battery usage.
Wasn't this that was fixed by going to Manage Applications/All and clearing data for "Contacts Storage"? I'm not 100% sure, but if you do clear the data for contacts storage you will probably need to resync any social network contacts. It won't delete your contacts though.

I have also seen this before, but not for a while now. I think it was an inherent bug with Android 2.3.3 and the Battery usage manager. Read through this thread where the DHD crowd have suffered the same issue...
http://forum.xda-developers.com/showthread.php?t=1069251
Edit: just noticed you've already found it!
It appears that the reported percentage of use was invalid. If you select Dialer from the list, it'll say only a few seconds of CPU time and a few kb of data have been sent/received if things are normal. The actual percentage of use is being mis-represented by the bug.
Your battery drain (which is definitely not normal) may actually be coming from a different culprit. The Dialer could be a red herring.
I'm pretty sure since I've been on 2.3.4 I've not seen it since. Typically after the first sync and Google Contacts are all pulled down onto my phone, I turn the Contacts sync off. No need to keep syncing contacts when they rarely change. I do a manual sync if I add a contact.
Use this to track down the battery drain...

If this problem has started suddenly and you are on stock, the above should help point the finger in the right direction. As Ben has suggested give my guide a read too, and see if that helps. The first things I do after putting a new ROM on are;
1. Turn off 'Always On Mobile Data' in Mobile Networks.
2. Turn off 'Network notification' in WiFi Settings.
3. Turn off 'Best WiFi performance' in advanced WiFi settings.
4. Turn off 'Pocket Mode' in Sound settings. (A bad drain that one)
5. Turn off 'Auto screen brightness' in Display settings. (normally set to 25%)
6. Turn off 'News', 'Stocks', 'Contacts' and 'Google Reader' auto-syncing.
7. Set Weather sync to every 3 hours.
Would be interested to know what you discover. If you need further help, please ask!

Stock 4.1.1 issues - Exchange, Media Server, Notifications

I've never had any problems with my Nexus S until my battery took a hit with 4.0.4 and now with 4.1.1 it's being a total pain in the ass.
For reasons I cannot figure out Exchange goes nuts. I turned sync off and didn't even check email yesterday but my battery had 10% left after 5 hours. With Gingerbread my screen was almost always the #1 battery user but since then others have taken away the crown. Exchange or Mediaserver with Android OS being runner up if not finishing first on occasion. I've been consciously trying to not use my phone for much because using it for much of anything means I'm down to like 3 hours on a charge. The phone never goes to sleep, the "Awake" bar is solid or a very intense bar code while the screen is more black space than anything by a large margin.
I am also finding that sms notifications aren't notifying me like they should be. Like I received a text 30 mins ago that I didn't know about until I went in and checked and seen one there waiting. Notifications are enabled. But I don't get the sound or the notification in the notification bar.

Google App - constant active use = battery drain

(Apologies if there's a better location for this issue)
Wondering if anyone else is having this issue or can at least confirm what their Google app is showing in terms of length of time in active use. I've been having unusual battery drain lately, without any noteworthy changes to my settings or apps. The Google app (version 10.82.8.21.arm64) is showing up as the #1 battery user, and details show time in active use as the entire duration of time my phone is off it's charger. Logically that makes me believe that it's constantly running, and doing so in a way that's draining my battery more than any other time over 2 years of ownership. I realize this one app is responsible for a LOT of the core Android/Pixel functionality, so it's hard to dial in very precisely what might be causing this.
Asking for fellow members to confirm what proportion of their "up time" the Google app is shown as in active use? Am I the only one at 100% on this?
Thanks!
My phone has been off charge for 17hrs 2mins and Google usage is the exact same time. It's only took 2% of the 40% that's been used but still very annoying. Also I don't think the is any way of stop it, I noticed this ages ago now and tried everything I could to stop it but nothing worked, I decided to reset my phone 2 days ago and it's still doing the same. I guess if it only taking up a small percentage of battery then it's not that bad but still really annoying that it's active for so long without any reason.
