[Q] Energy Efficient Mail Client - Nexus 6 Q&A, Help & Troubleshooting

I would like to ask for some advice-save trying all and every mail client for my Nexus 6. Point is, my current Type Mail client is imho using too much battery juice - roughly about 40% by the battery stats. Any suggestions, brothers, apart from "check mail every 6 hours and save that battery"?

I use MailWise. It's a very nice email client and I have mine set to check four separate email accounts every minute and my stats show it's used 9% of my battery today.

depends what type of mail. I use "nine" for exchange. It's pricey but the best exchange mail client I have used.

K9 - best I've ever used. Also - try changing your sync time to 15 minutes or more.

I used K-9 on my last phone but the UI is rather old-fashioned and I wanted a change to something nicer looking. So far, I haven't found anything that K-9 does that MailWise doesn't but there are so many email clients to choose from that it's very much a matter of personal taste.
40% battery use is a lot for an email client so I would have thought that almost anything would work better than the OP's current client.

Well there's your problem right there! Checking mail TAKES BATTERY.
I'm not trying to be funny.
Your problem is that you don't need to CHECK your mail to GET your mail.
Let me explain;
Use K9mail. Nothing else, only that.
Set it up to connect to your email server using ***IMAP*** and not pop3.
K9mail (and not other imap clients) can keep a TCP session open in order to receive new messages from the server when they arrive. Some people call this "push". It uses a feature of IMAP protocol called IDLE.

This is what Inbox needs. A sync interval option. I love inbox and I don't like having to turn sync off and checking mail manually. I will be looking for something similar to inbox, maybe with material design, with sync interval.

Reporting.
Thank y'all friends!
Now I have a list of your recommendations and I will go through it. But let me briefly report.
Changed sync interval on TypeMail to 30 minutes and got as low as 14% of total consumption.
Deleted TypeMail, installed CloudMail - use it currently with Exchange, iCloud, Hotmail (still remember this one) and Gmail. Currently the share of it is 4%. I do understand the IMAP "got_mail_flag", will check it as well.
Again^ thank you for your advices, XDA has assembled some great minds.

Push e-mail & Diamond

Has anyone tried to setup push e-mail on the Diamond? How does it affect the battery life?
Thanks!

Yes, I do push e-mail everyday (using Edge).
Fully charged Diamond last for 9.5 hrs for normally usage + pushmail.
It is only around 2/3 usage time for my Touch Elf.
Ouch... What do you call "normal usage"?
How many e-mails do you receive daily? Do you retrieve your e-mails as soon as they are on server or did you configure an "x minutes" check?

i have around 50-100 emails daily. poor me.
I have Exchange 2007 mailbox for company, it is pushmail and i got as soon as they are arriving on server. Simultaneously, I have another IMAP4 mailbox for my personal, i check it every 10 mins.
Same settings also apply to my previous Touch Elf, which have 1/3 longer running time for a fully charged battery.
OK I see...
I noticed on the HTC website that the specs for standby time are:
- Up to 396 hours for WCDMA
- Up to 285 hours for GSM
EDGE is GSM, so maybe that's the reason why it sucks the battery so much?
These numbers seem strange, that would mean we can expect a better battery life on 3G networks... I hope it's true!
Keep in mind after the first connection Windows mobile 6 doesn't close the connection. Then the battery life down very fast
Sorry I very newbie in push email... Is it necessary to install anything in the diamond to start receiving push email?
Is there any way to receive real push email from imap4 accounts beside forcing the diamond check the mail box every time?

Hi,
You can try emoze (emoze.com) it is free and you'll have what you need.
You can also try seven (seven.com) witch is the same.
mail2web gmail
Hi
I'm getting gmail pushed through mail2web.
Anyone know how I can get just my inbox and not all the folders and emails ? There's no way to set up a filter for just the inbox --> forward emails.
thanks.
@feridoun
I'm using mail2web as well, however I don't let my email be pushed or forwarded to mail2web. I'm having mail2web set-up to acquire the e-mails from my other accounts. And I only receive the inbox items. Maybe you can adjust something there to just get what you wish for?

Allowing mail2web to aggregate emails would work, but the trouble is, it uses IMAP and of course that mean it pulls emails from Gmail on a timed basis. If mail2web is using IMAP, I may as well set up a direct account on the phone to do just that.
The benefit of forwarding gmail is that mails would arrive almost instantaneously to mail2web and then be pushed to the phone.
Unfortunately in the case of gmail, all email gets forwarded including those that I have filtered out and don't want in my regular inbox, so every few minutes my phone is pinging to let me know I have a new email.

I've been using emoze for the past week or so while I wait for a Blackberry solution and must admit its pretty neat - I'd recommend it to anyone who's looking for a FREE and reliable service - from a corporate perspective if you have an existing Outlook Webmail system then this really is a great interim solution!
I would still like my BlackBerry service back though!

Is it possible to ad more accounts in Emoze? And is Emoze pushing HTML emails or TXT..?? This moment i use mobipush.com, but they don't support HTML push...
I'm not sure if emoze can support more than one account at a time in the "free" version??? Dont think so but you should check.
As for HTML or Text - Text only for now I think???
Thats a lot of thinking??? Their website give some good detail....
I use 4smartphone.net - for push email.
My battery needs charging every second day - my phone use is 1 hours calls 50 SMS and surffing 30mins inbetween charges.
I use momail.com and they support push email,
ihave never used that before and i dont know how to set it up in diamond,
any one that can guide me in the right direction?
I've tried to use my mail2web push-mail account on my Diamond, and I have to say that I was surprised that it did not decreased that much the battery longevity.
(compared to my wizard and trinity I used to do push-mail on)
This might be because by default, the settings are not high consuming on the Diamond (no wake-up on email reception, no ring, etc.)
since everything is done with the screen light off, I even think that it reduces more the battery charge to put on the light and check what time it is, than to have the push running in the back ground.
While we're on the subject of emoze, does it work (ie still push) while the phone is in standby?
Yep, it sure does.
I used to have my diamond setup for push and barely got through the day with my battery,
now I upgraded to the newest radio rom and set the mail sync to every 15min.
after this I have about 60% power left after one day.
I used to think push is a must, but honestly, 15min syncs are just fine. no mail cant be that important....

Push Email

Afternoon,
I finally got round to setting up my gmail account on my vario 3 and actually using it to send and receive emails etc but there is a small problem...
I have set it up to heck from mail every five minutes automatically....however, it doesnt seem to work...i think i have narrowed it down to power settings...
I have the backlight to go off after 10 secs and teh "turn off device" after 1 minute.
After that minute, the pulse that checks for mail doent run untill i do something with the phone to wake it out of standbye...
Is there a fix available for this other than modify my power settings (which i would prefer not to do)
TIA

Not sure I understand fully but if you want it to truely receive push email, then the data connection must be active all the time... and that uses power, lots of it. When you think about it this makes sense because how is the phone going to know when a new email comes in unless it's constantly connected to the internet. I had this setup with my Hotmail account after someone here told me how to do so but reverted back to only checking manually when I wanted it to after I found the battery life fell through the floor. You could make sure other things like bluetooth and wifi are turned off when not being used to maximise a charge but even just having data on all the time makes quite a difference.
from what i understand of push email, it uses a pulse to connect to the net, check for mail and then disconnect again...i have always had my internet connected on my vario and never noticed a increase in battery life when i have spent days without it off (on holiday)
is there not a way to make the 5 minute pulse ignore the screen being turned off?
Window Mobile Push Mail requires an Exchange Server (2003 or 2007 flavor) on the other end.
Without that your just using scheduled pull mail.
The heartbeat/pulse whatever you want to call it does continue to work when the device is in standby if you are using true push mail.

Do you know if that includes Hotmail? If its set up right, my Hotmail emails will be received pretty much instantaneously. Maybe they use Exchange Servers - I don't know if these can be configured for HTTP mail? Even when I had that configured though I still didn't get the Com Manager Microsoft Direct Push Icon to jump to life (it's always been grey).

@hotmail and @live use M$ Direct push, if you set it up for " as they arrive " emails. They do this however by keeping your phone constantly connected = kill battery. I had to shut my push email off to get a full 8hrs out of my battery.
Seven Push Email
Hey maybe you can try this little app called Seven from seven systems. It provides free true push email to WinMo environments. You can configure many accounts for example from hotmail, yahoo, gmail and others. There is a beta that is completely free of charge. Ive been using it for quite a while now (WinMo and Symbian) and Im very pleassed with its performance. Check it out here http://www.seven.com/ and go to the beta program section to download it.

Thats what I've tried in the past and certainly the emails arrive pretty quickly. I don't know if its genuine Push Email or just polling really often though. It also doesn't explain why the Microsoft Push Email icon in Com Manager never does anything other than sit there greyed out.

That highlights when you have a proper exchange account attached for push emial therefore isnt activated when google and hotmail are set up.
M
that 5 minute setting is not called "pushmail". it's calles "i'll ddos my mailserver by asking for mails every 5 minutes"
there are several free pushmail provider arround www.mail2web.com is one of them. they offer a completely free exchange 2003 account with active sync for contacts, tasks, calendar and pushmail
I find that the Windows Live 'As items arrive' option works well, though this seems to be pulling at high frequencies to provide the illusion of Push e-mail. I used to experience temperamental service but now it works flawlessly - as well as friends' blackberry devices. I don't have to keep my phone signed in to Messenger which is often advised to maintain a consistent delivery of e-mails.
I set up the Blackberry Connect service (£5/month) with T-Mobile UK but immediately reverted to using Windows Live (which is free given that you have a data connection) as the BB Connect service acts as a middleman, while Windows Live connects directly (or appears to) to your Hotmail inbox. Messages you read or mark as unread will be viewed as read/unread in your mailbox via a PC, folders can be synched and sent items are synchronised. Perfect for me. The only problem is reduced battery life.
For anyone who tried to use Windows Live 'Push' e-mail and found it to be inconsistent, see here: http://www.windowsmobiletraining.com/Connection/forums/t/2134.aspx.
I was always wondering about the battery too.
So I did a power drain test...
Hope this link helps!

Automatic mail check, when Diamond is in sleep mode

Hello,
how can I tell my diamond, that it shall continue to check for new mail every 5/10/15/30 minutes (depends on settings in Messages).
When I send the phone to sleep by power button or 40 seconds of inactivity, it stops checking mail.
Are there any settings to change?
Thank you!
I think that FlexMail will be able to make this work. Not 100% sure but me think so. You might want to download the demo and see if it works for you.
It will likely be a battery drain, tho. Ure much better off synching to an Exchange server and going push.
Good luck!
Hi, I never understood all the push email stuff. Could you please explain how it works in short? Thanks
set i.e. a free account to mail2web live
activate the mail aggregator
it will check mail for you and push it to the phone
battery DRAINS a lot, so use activesync settled to check mail every 5, 10, 30 mins or whatever you want according to your needs; mine is every 4 hours
note that your mail setting are via an exchange server now
for me works great
if you set up a paid account you will have more services...
Indeed flexmail do the job you only have keep Flexmail open, it support aswell idle which is push with Gmail, and a other favor off Flexmail is that it can check all your email acounts at once.

Thank you very much. I chose seven.com for my pushmail service. It works perfect and doesn't drain the battery at all!
Is there any chance to let the diamond ring or sth else, when received a mail? only the button light blinks!

[Q] Stock Email App and Activesync Push

I have 3 email accounts setup on my SGS (Bell, 2.1): 1 exchange activesync using the stock email client set on push, and 2 gmail using the stock gmail app. I have been getting very bad idle battery drain, it can be over 5%/hour while idle, and have also had my activesync 'stall' and stop retrieving new messages after a period of time. Using the 'other usage' page in battery history I found that the phone was not sleeping very much (at least 65% running) and on the 'partial wake' page the culprit was identified as "Email". When I switched my exchange account from push to 10min poll the running stat dropped below 20%, but email remains the highest partial wake usage. It seems that the stock email activesync push is having a hard time keeping the push connection running and this is both killing my battery and not retrieving my emails.
I have 2 questions:
1) What does the "Email" entry on the partial wake screen of battery history cover? Is it just the stock email app, or does it also include the gmail app?
2) I have also read from many people that push from an exchange server works great and is light on the battery. Could there be something about the particular exchange server I am using that is causing my activesync woes? Several iphones use push from this server with no apparent issues.
Thanks.
To follow up my original post, I have found some new information on this. I shut off my exchange/activesync syncing completely and my battery life went through the roof. My idle battery usage went from 3-10%/hour to under 0.5%/hour and I still had 2 gmail accounts syncing via push. The 'running' at idle went from 20%+ to about 1.5%, and the partial wake usage of 'email' went down to 0. From this I have drawn 2 conclusions: 1) The 'email' entry on the partial wake history does not include gmail. 2) The stock email app uses a ridiculous amount of time and power to sync email via activesync, i get between 6x and 20x the battery life when I am not using activesync. Has anyone else seen results like this? I am still wondering if this is a peculiarity of my exchange server or if activesycn is this bad in general?
Thanks.
Google & Microsoft
This is exactly what Google wants you to think.
Activesync is bad, so let me switch to Google, etc...
Google is playing with fire, in my opinion. People simply love outlook and exchange.
it's a million times easier for them to dump google phones and switch to a large available mobile OS's like iphone, Microsoft, Symbian, etc... instead of dumping outlook.
it's true Android is very attractive to users being on many devices and by many vendors but outlook is more precious and the alternatives google is offering are ridiculous compared to outlook.
after trying and searching right and left, i concluded that i have to sell both my Android phones back to iphone or Windows phone 7. Exchange Activesync is a red line.

K9 Mail eating more battery than 2h SOT?

Usually I get very great battery life (also very high screen on time thanks to DirtyUnicorns ROM + Kernel) but sometimes my battery is getting eaten away within 3 hours from 100℅ to 20℅. Looking at the screens I attached it looks like K9 Mail is eating so much battery? I have 2x gmail accounts + 2x IMAP (my own mail server) accounts active.
Are there some of my K9 Mail settings wrong or whats going on? Any ideas?
Thanks
Its that "mobile radio active" problem. Its often referred to as a bug.
Well according to google this is a common problem for some time now which hasnt been fixed.
Any other mail app auggestions?

this is the wrong thread for K9 discussions.. but I'm going to add to it anyway ?
K9 was my goto email app, still is in a way, but it just does not play nice with lollipop on any device. even using beta builds. if had no choice but to go to the gmail app since it can handle the exchange and ever changing bad decisions of Microsoft's email names and server labels. let alone having to run from website webmail settings.. yeah.. goto the gmail app, and give K9 a break until they get the wake lock issues worked out... other step may be to have tasker do sync toggle somehow..
go track down the beta builds and keep an eye out for changes that may be specific to its lollipop compatibilities.

Now I remember why I removed gmail...its missing "Mark as read" in the statusbar notification. Annoying as I wake up every day with ~15 Status Mails fromy servers which I usually "Mark as read" with one click (if the mail titles tell me that everything is okay with those servers). And since I use folders/filters/labels for mails I never delete/archive.

4 is a lot of accounts. I presume that your custom imap accounts are set up to push? Are your gmail accounts set up to pop3 or imap? If they are pop3, then your phone is going to continually poll the servers for new mail, and this will eat battery like nobody's business.
There is also a question of the correctness of how you have configured your imap servers. I don't know what kind of experience you have in configuring and maintaining imap servers, but there are some rookie mistakes that can be made that can have a severe impact on client battery life. Some of dovecot's default settings are actually quite bad for mobile devices. I'm not particularly familiar with other imap servers, dovecot is my server of choice.
What stands out to me is the "E" in your signal meter. Edge. The slower the network, the longer the radio has to be active in order to transfer the same amount of data. So imagine polling for a minute every 2.5 minutes (2 accounts). That is a lot of radio time and a lot of battery.
---------- Post added at 02:32 PM ---------- Previous post was at 02:26 PM ----------
Also not to create an argument here... but k9mail does very well on battery consumption on 5.x. Over this weekend (long weekend here in Canada), didn't use my phone much (construction/reno weekend), but something interesting caught my attention on Sunday afternoon. Having been taken off the charger 6AM SATURDAY morning (so it had been on battery for around 34 hours), it was claiming 4 days power remaining. That is ONE IMAP connection to a dovecot server that I maintain personally, the full time it was connected to an HSPA network (my service provider is exclusively HSPA).
So obviously, when everything is configured correctly, k9mail does NOT eat significant battery.

Thank you for your reply !
All my IMAP Accounts are using push (2x gmail + 2x my own server).
Could be that my server isnt configured perfectly. Mind giving me a few tips of what I should look for in my settings?
Yes I believe the battery drain could be because of bad radio signal. Maybe a Tasker script (if signal below 10% disable auto sync, which also disables push in k9) would help?
K9 in general has many settings which I am not sure of how they affect battery drain (e.g. sync forever or only last 31 days?) Which folders should have which priority and how to push/sync them. Would it make sense to make screenshots of my settings to compare them with yours?
Thanks !
Edit: In k9 I have not set all folders to class 2 except the important ones which are class 1 (inbox, sent, folders where new mails get moved from inbox to folder based on rules/labels). Push/sync only active for class 1 folder.
I did this because gmail has A LOT of standard folders and also an "all mails" folders which gets synced out of the box.
I also made a Tasker script which disabled autosync when I am NOT on 3G HSDPA or WIFI (maybe I should add 3G to the list of exclusion together with 3G HSDPA and WIFI?).

A quick look over my notes suggests looking into the setting "imap_idle_notify_interval". Dovecot's default is 2 minutes. That means that the imap server will be sending over a battery eater every 2 minutes regardless of whether there is a push notification or not. Between 2 accounts (edit: and multiple paths per account), they could all hit at the same time, or they could hit at different times, so you're looking at server initiated wakeups all over the place. Note that k9mail has a default client initiated wakeup at 24 minute intervals. RFC2177 specifies 29 minutes -- the k9mail default is matched to give a little slack to let the server renew the connection 5 minutes after the expected client-initated wakeup. So set the server to 29 minutes.
Yes I believe the battery drain could be because of bad radio signal. Maybe a Tasker script (if signal below 10% disable auto sync, which also disables push in k9) would help?

That setting really shouldn't affect anything, since ancient messages won't be changing much. I.e., there is no "sync" on stuff that remains the same -- it just gets downloaded once and sits there.
Thanks !
Edit: In k9 I have not set all folders to class 2 except the important ones which are class 1 (inbox, sent, folders where new mails get moved from inbox to folder based on rules/labels). Push/sync only active for class 1 folder.
I did this because gmail has A LOT of standard folders and also an "all mails" folders which gets synced out of the box.

I think I may be only performing push on inbox. IIRC, k9 creates a new idle connection for *each* path. This isn't a flaw in k9mail, but a limitation in IMAP protocol.
More edit: about the client-vs-server initiated wakeups.... if you set the server-side to more than the client side, then the server will not actually send the wakeup at all. Why would it if it knows that the connection has already been refreshed by the client within the timeout? Once the client has control over the idle refresh, k9mail can schedule the refresh messages in batches to send out all at once within the same system alarm/wakelock.

A quick look over my notes suggests looking into the setting "imap_idle_notify_interval". Dovecot's default is 2 minutes. That means that the imap server will be sending over a battery eater every 2 minutes regardless of whether there is a push notification or not. Between 2 accounts, the two could hit at the same time, or they could hit at different times, so you're looking at a server initiated wakeup EVERY MINUTE. Note that k9mail has a default client initiated wakeup at 24 minute intervals. RFC2177 specifies 29 minutes -- the k9mail default is matched to give a little slack to let the server renew the connection 5 minutes after the expected client-initated wakeup. So set the server to 29 minutes.
Is that even possible?

Well I could do push only on inbox and sync (every 24hours) on folders like " sent" and other semi-important folders.
I also made a Tasker script which disabled autosync when I am NOT on 3G HSDPA or NOT on WIFI (maybe I should add 3G to the list of exclusion together with 3G HSDPA and WIFI to disable autosync only on 2G?).

I've never played with tasker in this space, so... try it and see how it works !
