When I first got my 8125 I got about two days of normal use out of it before I had to recharge. I setup a IMAP email store and set it to check for emails every 10 minutes. My battery life now will only last me 24 hours before I have to recharge.
If I setup push email on my device will the battery life stay the same as checking my email via IMAP or will it get better/worse?
with my battery properly conditioned and using push via AKU2 and exchange 2003 SP2 I get around 3 days usage.
I've read that the MS solution also leaves a socket open to the mailserver.
The difference would then be the amount of data sent between the device and the server...so instead of an IMAP login and header listing (or worse, ssl imap), you do it once and stay connected and simply wait for it to come down the pipe. The radio and GPRS stays active, but not much else.

What exactly do you mean by properly conditioned?
I'm getting slightly less since I went to direct push. It's right around 2 days now where before I would go 2-3 days. Could be that I'm checking emails more often now too though.

The possibility of T-Mobile bringing unlimited GPRS is great. I can't wait to get my Direct Push email sorted. BTW - will we have to pay for an extra service from T-Mobile (UK) to enable Direct Push or would having the GPRS be sufficient?
Another thing that has hit me was whether we'll have to enable GPRS on all day....Is this necessary or will it use a sms based system?
For people who leave their GPRS on all day (for Messenger+email for example), how long is your average battery life on your Wizard?
I don't think many complained about the battery life on the Blackberries - but I suppose they weren't that power consuming right compared to the Pocket PCs?
my battery life is pretty much the same....using push mail service for a little more than 2 weeks now......
I haven't actually got my Wizard yet (still stuck with Magician) - but how many hours are you looking at - and what usage is that based on?
So I presume you will have to keep GPRS on at all times right?
Thanks again for your replies
my GPRS is always on. Usage is as follows:
I mainly use my wizard for phone, text, and e-mail. Occasionally streaming some audio, and surfing the web (slashdot.org, wap.yahoo.com, etc...)
I need to charge my phone at night before going to bed and I'm using it the following morning by 9am. I charge it in the afternoon and during lunch when I'm in the car, and by the end of the day before I put it on charge I have about 18% battery left.
From 2/28 until today (3/13) I've used
980 anytime mins
260 weekend mins
200 mobile to mobile
300 nights (after 9pm)
11MB Internet Data
221 text messages
12 picture/video messages
so from that you can surmise that i'm a moderate user (some might say upper moderate).
hope that's enough for you...
note: in the begining for about 5 days i didn't have the push mail
GPRS on all day and battery life
I am planning on getting a Wizard (have a Magician right now). I have found that keeping GPRS on all day to use my push email client prevents my phone from going into standby and massively drains my battery. (Backlight will go off, but screen does not switch off entirely, seems to be GPRS over-riding my power settings.)
How does the Wizard handle this? Are you able to keep GPRS ticking over but still have the device go fully into standby mode?
Wondering if my issue is device specific or this is a normal facet of GPRS always-on usage?
Mine goes to sleep/stby as-designed with GPRS constantly connected. I, too, have noticed very little (if any) difference in battery life since the new ROM upgrade.
I've been using the qtec test since the WWE version came out and now the iMate Rom on tmobile uk.
I've had push mail working for an entire month of my contract now, and my data usage dropped by at LEAST 10mb a month. I mainly use the web for an hour a day surfing bbc news, the register etc. I have the push mail enabled from 6am until 6pm. using I use about 32 of my 40mb, this month I only used 16mb. I was syncing every 30 minutes on the earlier ROMs during the day, so I has been an amazing improvement.
The other good news is my battery life has increased by a large factor with the iMate rom. On an evening after just GPRS usage (no wi-fi) I had 98% battery, the best I had managed before was approx 70% so I am very very happy.
I don't use the phone very much,only about 5 minutes per day so obviously this helps my battery life too!
By the way yes the GPRS keeps the constant connection while in standby, and wakes the phone a little like a text message.
I am confident my findings are accurate, I read in the exchange server blog direct push works by opening a http request and waiting for a response or timeout. There is little overhead in this, I believe the battery overhead should be little more than having GPRS connected permanently (or between the times you use direct push)
Hope this is useful!
wow thanks stevieg (glad you are helping us pocket pc users as well as liverpool! )
Direct Push and Standby
Have anyone of you had a problem with Direct Push when the Wizard is in standby mode? It works fine when I test it and the screen is alive, but when it's on Standby/Sleep the mail doesnt come in.
Is there something I need to config on the phone or Exchange?
Thanks
Just wondering if anyone else is having this issue. I set up my Wizard for Direct Push with the Exchange SP2 server at work. No prob though I did get duplicates. Anyway, yesterday, it worked great, received e-mails even before the computer at my desk, but by the end of an 8 hour work day, my battery life was down to 43%. Is this supposed to happen?
Today I tried disabling the push and after the same 8 hours I have 97% battery. Anyone know what to do about this?
Thanks for the help.
Not fully understanding how the push email system works (I don't have the need for it, nor the pocket to fund it's use on Australian tariff plans), but doesn't it just stay connected to the server through GPRS, sending a 'heartbeat' every couple of minutes to keep the connection alive?
I think it is something like that. If that is the case obviously it is going to effect your battery life as you are using your phone as normal, plus fulltime gprs use and then the backlight/processor when reading/replying to the emails.
Hello all,
I'm using PushMail with MS Exchange and I am very happy about figuered out this feature. But now I have a new problem. If I have charged my battery up to 100% it only need half of a day to be empty without using my hermes (only UMTS for Push Mail)
Has anybody the same problem or a sollution ?
Thanks
sunmaker
Ok, try this. Open your maillbox in Outlook, then send yourself an email from another email account. Does the mail item hit your hermes and your inbox at (about) the same time?
note: if you have cache mode set in outlook then it should hit your hermes before you see it in your inbox.
If you can't access your mailbox with Outlook, then use OWA and hit refresh often to see when the mail item hits.
I suspect that you're going to find out that mail to your Hermes is delayed for up to 7 minutes from the time you see it in your outlook/owa viewed inbox. If you are seeing mail hit at about the same time, try this test periodically for an entire day to see if there's any time that this isn't the case. Let me know what you find out!

It's UMTS that is so power-hungry.
download Daniel Herrero's Bandswitch and force GPRS-only, to see the immediate result. Let us know; in my case it improved battery life from 20h to ~80h.
This doesn't necessarily account for a one half day drain. I'm on UMTS direct push and I go two days between charges. There's something else that I'm thinking about here. If sunmaker is seeing the delay I'm looking for then I'll reveal the reason.
Btw: on mine, email always hits my TyTN before I see it in Outlook.
You should be able to survive around 2 days with UMTS + DP .. and approx 3 days with just UMTS ...
You need to check for any processes/services that might have excessive CPU utilization ...

I have around the same usage in between charges. I get around 2 days with PM+UMTS but if I use my device extensively during the day i charge the same night.
half a day to empy sounds like there is a process chewing up your amps, or the battery is faulty.
It entirely depends on usage.
I get two days (similar to others above) using push and UMTS.
However, if ihave wireless enabled and bluetooth too, and using a bluetooth headset and make a couple of hours of calls in the morning, i'd be hard pressed to last the day out on the same charge.
I'm running Pushmail and UMTS also Bluetooth is enabled all day.
i spend about 35 minutes a day in calls and do send about 5 SMS mess. a day.
My battery last for about 20 hours.
Like i said, entirely depends on usage.
i recieve close to 30-40 work orientated emails a day ,of which at least 20 get replies instantly. add in 2hrs easily of actuall call talk time and its easy to see where my battery life goes.
a lot of people whinge about battery life, but if you expect alll the bells etc that a good WM5 device has theres going to be issues with long battery lifes.
My blackberry 8707g using UMTS and recieving maybe 10 emails a day barely last a day and a half from full charge. Thats without much else, and probably 10 mins of call time. SO i consider the Dopod 838Pro (or Hermes! ) to have more than adequate battery life for what i use it for. Besides a great, powered car holder and hard wired GOS device in the car has just about made this Hermes the best of any unit i've used, WM5, WM2003, Blackberry and palm inclusive.
thank you for so much response.
I have about 30 Mails per day some SMS and 60min phonecalls. I'm using the 1.20 radio so far. Could it be the radio ?
The radio versions i used before I have a lot of trouble with. Because my Hermes always loged out.
I have no other progs in the memory only the necessary (CommMgr, Active synk, Email).
I've ordered some new batteries (1350mAh ans 2.400(!) ) So I will look and see if it is the battery.
Hi
I have read a lot of threads about short battery life, but so far none of those applied to me. I have recently purchased this great device, and normally it gives me 2 days of usage time with a fair amount of fiddling etc, and no activesync. Now the main purpose for this purchase was the Activesync feature, as I have an exchange server pushing me my mail. I have the following settings:
Exchange 2003 SP2 without SSL certs/encriptions
Active sync set to download mails upto 0.5KB and from all times, not only the last 3-5 days, etc.
Active sync is also set for immediate retrieval, which leaves the phone with a permanent GPRS connection. There are PEAK times set, from Monday through Friday between 8AM to 6PM. Off peak times it gets it at every 2nd hour.
My battery lasts 12-14 hours like this, and I dont touch the phone much, plus dont have more than 20 minutes talk time per day. Yesterday I arrived home at 10PM with a dead battery already. This is really bad that I cannot even make it through a single day.
An addition to this the phone gets really warm, but only at the very end of its battery-life, lets say from 30% to 0 it goes in less then an hour or 2, and warms up pretty badly.
I also have the BandSwitch utility keeping my phone on GPRS only, and killing idle connections that are non-used for over 2 minutes. This I guess only takes affect during off-peak hours, but even in those hours, when I check my phone I can see a GPRS connection on for like 20-30 minutes. So I guess Bandswitch doesnt always do a good job.
Any hints? This is really annoying,
Thanks a lot,
Ben
Hi, sorry if this has been asked, but I'm a follower of the entire Nexus One forum, and could not find it.
It drive me nuts I cannot find how to set synchronization for the Gmail account. I want to have it check for mail every 15 or 30 minutes, and not continuously as how it looks is happening now. I think this is one of the reasons my battery drains so fast in standby.
Is this possible? ( I almost swear I saw it once, maybe at initial setup of the Nexus), or it's just my ex WinMo thinking?
Regards,
Alin.
As far as I know Gmail is push, no?
I need the answer too, but it seems that it is pushed mail.. it draws the battery quickly.
I leave my sync on and don't seem to have any significant battery life problems... I mostly leave my phone in 2g mode though, activating 3g/wifi when I actually want to do something.
I charge once a day when I am sleeping usually, but it seems fine to me.
Someone please correct me if Im wrong.
Im under the impression that Push email allows Gmail to stay completely idle until a wireless msg is sent and activates the updating process.
Thuse greatly reducing battery since it only has to check when told to instead of periodically.
Unless of course your constantly getting emails in which case it may be ALWAYS being told to check.
Guys, how long does the N1 need have to last. I life in an area where I can charge the N1 every night while I'm sleeping. It is set to Autosync with GMail and I use it quite a lot, maybe around 40-60 min. Internet and a few minutes phone and a few SMS and (at least now to get used to my new toy) a lot of playing around and about 30 min MP3 a day. It's empty when I go to bed but who cares? I got power beside my bed and do charge it while I sleep. That's how it should be, or? If I'm away and maybe don't have a power grid (where the heck is this today, in the middle of a dessert or rainforrest?!) and need more than a day than I would switch off the Internet and syncing and put down to display brightness.

The topic has less to do with how long the battery has to last and more about how do you change the GMail app to poll for new mail rather than relying on push. Mail sent to GMail account is by no means urgent and I for one don't want to drain my battery for a feature that I do not need.
For those that are skeptical that push technology drains the battery - the following is a quote from GMail's blog regarding the GMail app for WinMo (sorry I can't post the link due to user restriction): "Once you're set up, new messages are normally pushed to your phone within seconds. While this type of speed is pretty awesome, push connections tend to use more power than fetching at intervals, so don't be surprised if your battery life isn't quite what it used to be."
Anyways, I haven't found a way to change the GMail application to a poll model rather than push so as an alternative I've setup K9-Mail against my GMail account and have it poll on a regular interval and disabled the GMail application altogether.
So you want your Gmail account to update at a predifined interval (like every hour?)?
This is simple: Open up the Email App (NOT Gmail), and enter your full gmail account ([email protected]) and password. It will set up your Gmail account in the Email app. In this app press Menu > Account Settings, and set the email check frequency to your liking. You can also set other options like delete emails from the server when you delete them on the Email App.
In this way you will use the Email app to check emails, meaning you can turn auto-sync off and save battery.
You could also sync your email account once. Then turn off sync. And manually sync your email anytime you want to check for new mail. Since it's not "urgent" as you said.
Or do as melterx pointed out.
Thanks guys for all solutions provided. I'll test them out and see what's happening
Answering to the guy who mentioned about how long should battery last, well, I'm simply not used to charge my phone daily. I had Touch HD before the N1, and with same usage (phone calls, gmail sync, internet) I had almost 3 days with a full charge.
Well, I'm still blaming the "new phone" factor for my battery draining problem, and I mean by this that I'm simply using it too much compared to a normal, "already used to it", usage.
But again, there are other topics for battery usage, so let's keep this only for email sync options
turn off auto-sync. when you want it to fire up, fire it up, then shut it down again. i went all day today, and ran less than half the battery off, because it wasn't polling over and over and over...
I'm not sure how much push drains the battery. One of my Gmail accounts is a work account. I have it and my personal email on push. Went for 10 hours, got about 40-45 emails with several calls and numerous text messages and still went down to 57%. I do have my phone on 3G most of the day(gotta love Atlanta).
