[Q] Email is killing my battery!

As stated! Literally 78% of battery usage. I have only just started using email on my phone! Battery was amazing up until using email. I'm on rooted 2.3.3! Could anyone help.

The stock email app blows for exchange connectivity. It constantly hangs on me (the retrieval of email that is). I find when you have an area with a flaky connection (in and out of 3g), you get these issue. With it comes battery problems I've noticed.
I use touchdown for my primary exchange account to solve the lack of incoming email, but it too has battery issues if when it goes in and out of 3g coverage. It was fine until an update earlier in the year (on my old phone, then i noticed the battery issue, still notice on the arc now).
Are you using exchange or just regular email? If you notice your battery draining quick, its probably best to do a force close on it. You should be good to go for a few more hours until it happens again and the cycle repeats. The issue has been around wince 2.1 and I'm not sure why google doesn't get around to fixing it (I'm assuming the mail app at least uses a background service by google as I had the same issue on cyanogenmod since android 2.1). Its a well known issue.
I'm sure this doesn't help, its more of a "Me too".
I hope it gets better for you.

Yea its exchange mate! What a nightmare this is! Work email too so really need to find a work-around for this! I don't seem to have the issue of incoming email, it purely seems to be the battery usage! What a shame. thank you for the speedy reply.

you could try forwarding all your email to your gmail/ googlemail account and use that instead... doesn't solve the problem of replying though.. but you would at least get instant notications of incoming mail, without screwing your battery.

I also have this problem on my Arc - Accounts: Gmail & Exchange. With use of Green Power (Battery Saver which enables data traffic only 1 minute, then 10 minutes data traffic off) this drain-problem becomes WORSE. Before Update to 2.3.3 Green Power really saves some battery, after update 2.3.3 Green Power makes the drain more.
Best solution for me atm is: use only 2G, and don´t use Battery Savers like Green Power. I have to try playing around with exchange refresh settings (Push, once per hour...)
With this my battery drain ist about 2% per hour (no wifi, no gps, no calls... Only phone idle). Not perfect, but best i can get atm...

I use moxier mail for exchange mail. It's a pretty expensive app, but works flawless for me. Maybe there are some free exchange apps too try to search the market. Moxier mail doesn't even site up in my battery usage stats.

Thanks, I will give moxier mail a try.
Hard to justify since I bought touchdown already. I've since turned off push in touchdown and set to 15 minute intervals. Not ideal, its no longer draining my battery.

I've had this same problem for a while after updating to 2.3.3, I think the general solution is to NOT use push email and rather, set a interval (15 minutes or greater).
If you're in an area with scarce connectivity, the email application apparently continues to attempt to sync even with no signal so in that case, maybe a 3rd party email client will be better. Though apparently the popular K9 mail doesn't support active sync =/

Can anyone tell me how to set up email using Moxier? I cannot get it to connect to my exchange account at all, i have tried all possible combinations. My email address is [email protected]. Can you tell me what my domain would be? (previously using stock app i used @broadfieldprimary.herts.sch.uk - this worked fine) What my server would be (using stock app, I used db3prd0204.outlook.com - and this worked fine also. But trying to use Moxier - Paid - I cannot get any connection to this email!!! I'm sorry if this is a basic question, but If anyone could explain the set up I would need I would be eternally greatful!!

[Q] Android mail eating battery! Please help!

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?

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...

[Q] Does calendar sync use much battery?

Hope this isn;t too dumb a question. Since the early days of my smartphone use, I always turned off sync's to get better battery life. I think most of us still do that.
If I leave Google Sync for my calendar will it use much juice, or does it just sync if there has been an update?
I've started using my phone more now to maintain my appointments in the field. I could always just sync once at the end of each day.
Just curious.
Thanks for any info.

Any sync or push is going to use more battery than if you have it shut off, but I have most of my sync options set fairly conservatively (every 2-3 hours) and I'm getting a full day with steady use (I'm currently using SkyRaider 4.1). I would suggest using a calendar app called Jorte, free in the market. It's a far more robust app and widget than the stock app in my opinion, and has a lot of setting options to customize view and sync.

[SOLUTION] Anyone having crazy battery drain, turn off your EXCHANGE EMAIL!!!

Although a lot of people here are claiming that they get great battery life off this phone, especially with custom ROMs and all kinds of tweaks (SetCPU, Juice Defender, etc), I find my experience to be the contrary. My battery drains 8% with screen off, and 25% with light usage, no matter what tweaks I use. No I'm not kidding. I even removed all my user apps (so no facebook syncing no nothing) and bought a new OEM battery and NOTHING HELPS. And I do hear from time to time that there are minority of people like me who have this problem.
But finally with the hint from someone in another thread (thanks to him big time), I can confirm the real cause of this crazy drain is your EXCHANGE EMAIL!!!
Whoever with ridiculous battery drain, turn off your exchange email or set the sync option to "manual". This will solve your problem! After I set it to "manual" my battery only loses 1~2% per hour while screen off. A HUGE improvement. This problem has been driving me nuts ever since I first got this phone but now it's resolved.

Haha I remember reading about your frustrations with your battery life in your posts. Very glad that you found the solution. Enjoy your kick-ass battery life now.

Umm... some of us like our Exchange Email sync and are willing to carry multiple batteries and swap them as needed when Touchdown drains the pack dry...
FYI, this is also an applicable fix on most other phones, iphone included. Exchange push chews up a lot of mAh's...

What is exchange mail and how do I disable it?

I had similar issues and it was frustrating the heck out of me. I needed Exchange because my version from Telus did not include direct Hotmail account support. And the battery life was draining so fast I could watch it drop.
The solution is to download seven.apk which does include direct hotmail support. http://forum.xda-developers.com/showthread.php?t=960269&page=14
Don't use the Market version of Official Hotmail created by Seven. It's a little bit buggy still and won't let you update or enter contact information.

i use K9 mail for Hotmail accounts
Microsoft opened up their POP and SMTP even for non premium users

Battery Drain issue - Exchange service eating up battery

Hi All,
I have had this beautiful device Ascend P6 for more than a couple of months now. Used ROMs B107, B111, B118CN, B122 and currently on B125. I must say that this is a very good device and give me close to 12-14 hours of battery life with not so high usage.
I have configured 2 company emails using activesync on Exchange and have kept the refresh interval at 1 hour with 3 days of sync for both the emails. What bothers me is that when I check the battery usage the Exchange services takes up more than 50% of battery every time. If this can be reduced, I am sure that the battery would rock.
I have attached 4 screenshots with the battery usage config, details on exchange service and my sync settings on both the emails.
Can somebody let me know if anything can be done to make this better, or should I just stay with it.

The amount of transfered data is not really high but depending on the amount of contacts and calender entries it can take a long time to get it synchronized.
If you don't synch contacts and calendar every hour you will encounter more efficient battery drain.

Still the same

I did try this and it helped upto an extend so and my keep awake time for this service has reduced to half. Still the service is taking up almost 40% of battery and I think there should just be a better way of doing this.

I sync with my works exchange and have never had these issues (been on 3 different roms, currently on 122), I have it set to push, days to sync = all, sync email and calendar but not contacts. I only sync with one account though, maybe try removing one account and seeing if that helps, and then re-add and remove the other?
One issue I did have with the stock version was the lack of ability not to set a quiet time, ie weekends and at night, tried a few other apps but didn't like them as much. I just use the profiles at night to turn auto sync off, and at the weekend I just ignore the emails
I get about 2 days out my battery from full charge. I also have it syncing with hotmail, use bluetooth in the car for 2 hours a day, browsing the web etc. So i'd say i'm a mid level battery user.
The latest version of the email/exchange apps you get with the nexus 5 have been released, maybe try them? I installed them on my P6 fine, here they are here...

Let me download them and install. Hopefully they will be better than the default mail app. Still not sure, if I should go with this or the Touchdown

I found it used far much more battery and data than the default app. Loads of extra addons in it, but for me I just want to check emails, reply etc. Nothing fancy.

Similar issue with Moto G 1st Gen India
Hi,
I am using a moto g 1st generation. I have recently updated to lolipop. After upating to lolipop Microsoft Exchange Services eating 49% of my battery. My sync was off.
