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

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...

I've set up my gmail account with my htc desire and can access my emails fine using the Google mail application (the one with a red M in an envelope). However, to test the push email function, I emailed myself from another account. On my pc, the email arrived instantly, but my desire didn't notify of a new message till almost 15 minutes later.
Is there a setting somewhere that i might have missed - to enable retrieval of emails as they arrive?

Were you using wifi? Push is really crap over wifi on the desire, the only time I get the push email instantly is when I use mobile data instead.
I was having the same problem and think that it doesnt allow push.
I then set ot up in exchange activesync but im worried about battery life :

Yeah I always use mobile data too. I hardly ever use wifi unless I'm downloading something big to my phone such as copilot maps.
Anyway, I've set it up with activesync now and push is working flawlessly. Sometimes I get notified of emails before they even arrive on my pc.

hot-fuzz, I'm gonna start tomorrow with a full charge and have active sync running all day. I'll post my findings here if I observe dramatic decrease in battery life.
got it set up on the one i am using and it seems to work just fine. Emails appear on the phone within seconds of arriving at Gmail.
I do sometimes get periods where it is a bit slower though, i think generally when in a bad signal area where i only have 2G. I'm guessing when it has lower signal or only 2G, it may slow down the checking to save battery power or bandwidth or something....

That would be very useful. Thinking of doing it myself.
If i have mine setup for every 5 minutes thats 13 times every hour (including on the hour). I need to know if exchange polls take up more battery than checking 13 times an hour, if i get less than 13 emails an hour via exchange (which i do).
hmmmmm
Be interesting what peoples findings are on battery life and different ways to grab email.
I want to get back to the main topic.
I came from HTC Hero where Gmail push (in the gmail app) worked perfect - also on the 2.1 custom roms.
Not on the Desire it does not push the mails instantley. I don't want to go the way over the HTC Mail app...
Anyone has an idea how to fix it?
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)

Ok its been pointed out that "solution" is a poor choice of words but rather I have pinpointed the culprit mmaking android os drain the battery. I would like to first start off by saying that the reasn I chose to make a new thread was because the "Android OS" consuming battery thread is pretty much all over the place. Its not very informative if this bug is plaguing your battery life. Way too much random talk about wifi and other things. I dont think I saw one mention of adb or a logcat in that thread. No one is really doing any testing and sharing information so that we can get to the bottom of this. I would prefer if this thread was more informative where you posted what you did and what the result was. Mods if you feel as if my post should be in that thread then so be it. Enough with my rant here goes.
The problem I have found is that something in the google account is making the suspend function go bonkers. When the phone attempts to sleep it ends up spiking the cpu pretty hard for a good amount of time too. This is why some of us are not getting the phenominal battery life others are boasting about. The temporary solution I have found is to do a reset and not put any google account information in. This is why when some people have reported they did a reset and they still have the problem that its still there. Dont use your gmail. I know I know... the solution kind of sucks but its temporary until a real fix can be pin pointed. I am trying to get to the bottom of this as fast as I can. Thanks to Sprints new return policy I would like to do so as fast as possible. I have tested this on 3 phones so far. On all of them I did a reset, and then only installed the amazon appstore and watchdog. The amazon appstore was so that I could get watchdog. No cpu spikes alerted by watchdog on any of the 3 phones for the whole day. At the end of the day I added the gmail account that the user had been using to one of the phones and watchdog began to alert shortly after the screen timeout kicked in when the phone was attempting to sleep. Reset the phone again without adding a gmail account and the problem was gone again. Yesterday I began gradually installing other apps that I use day to day to continue my testing such as maildroid, twitter, etc. I got through the whole day on 1 charge with no problems. I cant remember how long I was on wifi but lets just estimate it was between 4-6 hours. This is with two accounts pushing to maildroid using IMAP idle so it doesnt have to poll a server which is better on battery. The official twitter application also uses push. I also have groupme installed which I use for my business to communicate with team members throughout the day. It is a chat application and it also uses push to send messages. Also I have left all the stock widgets in tact during this whole period of testing. The weather widget is set to refresh at 4 hours i think and the news widget is on manual refresh.
My next steps are trying to figure out why certain gmail accounts making suspend peg the cpu so hard. Today I plan on using one of my backup gmail accounts that doesnt have any contacts or apps purchased. I will be posting my findings later. I do apoligize for being so long winded but I hope this post helps someone out there and helps the community get to the bottom of this bug. Thanks for your time!
You call that a solution? Not put any Google Account information in? Thanks!

Im not going to remove my google account but instead I mail turn off mail sync and contacts sync and see how that goes for a day.

You can set up the built-in email client to still sync your google email. You just will get your email through the email client rather than through the gmail app. You will also not be able to download apps, but you will at least be able to check your gmail.

Thanks for this thread!
I am far from being able to provide in depth troubleshooting, but if it helps anyone, here's my progress so far. Two things:
1. Before seeing this thread (without changing anything) I had the phone in airplane mode for about an hour in my pocket and when I checked the battery stats, for the entire time the phone was in airplane mode it was also awake. Screen off.
2. After reading this thread, instead of disabling the Google account, I just un-checked "sync" for everything except gmail in Accounts and Sync (so calendar, contacts, books, etc. doesn't sync unless I manually do it)
After about 2 hours with this setup, android OS battery usage has dropped way down.
Hope this helps someone!
Good grief, you people are so ungrateful it is amazing. The OP is not suggesting you will never be able to set up your Google account. He is trying to narrow down where the problem exists so effort can be focused there rather than other places mentioned like WiFi. This thread is for us to work together to find a solution.

Worked for me. I also re-enabled all of the syncs on google account and the problem has not returned, yet.
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 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 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..?

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.
Greetngs. Manually loaded the zip the other day for 4.1.2 on my completely stock Sprint GS3. Other than the normal "holy crap" battery consumption for the first couple of cycles and the fact that I could cook a grilled cheese sandwich on it, everything's been OK except for these two problems:
1. This was the easy one. AVG AntiVirus Pro didn't like something on the update and it was stuck WFO and draining the battery in about an hour. Interestingly simply looking for running apps in the stock applications area didn't show anything. System Panel did. I deleted the AVG, reloaded it and all is well.
2. This one's not resolved. I've Googled as well as searched XDA and can't find an answer. Short version is that regardless of what my mail settings say, it's not going out for a sync to my Gmail accounts, nor AOL (I know....) and my Exchange account isn't getting "pushes" either. I've gone through the global mail settings as well as those for each account. All set to push if possible or 15 min if not. Everything is "prime" so it's not some goofy issue with being outside of prime or roaming. Roaming has all the same settings.
I can manually hit a refresh and it works fine, but it's obviously not supposed to work that way (at least it never has).
Any thoughts? Oh...and I've done a battery pull...haven't done a hard reset but I doubt that's an answer for this.
Thanks for your help.

Aha! It seems as though the update turned off the "global" sync (on the scrolling drop down tool bar at the top of the screen). That said, it also defaulted all my sync options to "disabled".
Better now!
