Guys,
pretty much as the topic says...it drains about 40 to 50% a day when it is idle....if I am using it it can be anything up to a 1% a minute.
Any hints on where to look - tried using battlog to log the usage but i cannot open the subsequent file at all.

Wiggz,
Try checking if you're in a dead-zone with no reception? (Your phone may be constantly trying to search for a signal). Do this for Wi-Fi too. Make sure it is not constantly scanning for a network.
Similarly, open up your task manager. How many programs do you see running in the background? Remember that pressing X in Windows Mobile does not mean it closes the application, it only means that the application is minimized.
Cheers.
Wifi is hardly ever on. My signal is always constant, but I have my data connection on 24/7 for emails. The only program I ever see consume CPU power when idle is "changescreen". I always check that a program has closed properly when I click the 'x'.
I know data connection on eats some battery but jesus - not that much surely?

Wiggz,
The question remains, how many programs do you see when you open up the task-manager? You did not answer the question.
From what I've observed with my friend's Toshiba Portege, he lost 30% in an hour. He did not realize that he had 15-ish programs "idling" in the background with very little RAM use. Long story short: Turn everything off if you don't need it and just keep the Task Manager running. He now goes through the night with 1 ~ 2% loss.
Good day.

When I open up task manager I see 4 applications running (taskmgr, manila, cprog x2) - when I check the processes I have many more obviously. However these are all processes I'd expect to be running (gwes.exe, cprog.exe, device.exe, services.exe etc...)
Any more advice?

Wiggz,
Unfortunately, that's all from me (I dont even have this phone yet, I'm saving up for it in the next couple of weeks). Try turning off your data and see how it goes. But damn, 50% loss just on idling, something in the background is definitely killing the battery.
Cheers!
Thanks for the help anyway - annoying the crap out of me. My Artemis used to go for days without needing a charge...I suppose my battery could be screwed but I want to troubleshoot first before I bite the bullet on that one - suppose I could hard reset and see what the drain is?
Things idling in RAM should not have any significant hit on the battery life. However, having the data connection on 24/7 will indeed kill your battery life, especially if you're using 3g or higher (Edge drains alot aswell, but not as much as 3g and higher). Since emails seem important to you, I'm guessing you have it set to dl every 5min (which is the most frequent setting). If applicable, change it to 10 or 15; granted it's possible you do need to get your emails ASAP and you need the 5min frequency. Now regardless whether you changed the frequency of the auto dl or not, set your data connection to terminate after a 1min of not being used. This should help you get a good bit more out of your battery.
(I have emails dl every 30min and RSS feeds and push pages once an hour. Data enables itself when needed and then terminates after a minute of not being used. This allows me to get much more than a days usage out of the phone. The only way I kill the phone is if on top of all that, I listen to music/radio for about 6 hours)
Hope it helps
oh, and in case you don't know, HD Tweak is one way to terminate data after X amount of time of not being used.
do you have stock or cooked rom btw? duttys v3 xt, for example, is known to drain battery a lot.

Cheers for this. I have HD Tweak and have tried that data connection termination setting before, however there is a little comment along with it that it can stop data and/or voice calls. Has anyone had any issues with it?
Thanks
i had similar problem, battery got drained overnight or during the day with a speed of light... but in my case the bad boy was Palringo (IM) which was auto starting with every phone reset and did not show on taskbar...it is so bad that it drained fully charged battery in aprox. 6-7 hours. so now i hardly use it, and whenever i do i make sure its closed properly....

personally I have had no issues whatsoever. The voice calls that I'm guessing they're referring to is VOIP which uses your data plan to make the call as I don't see why it would interfere with normal calls. I think the easiest thing is just to give it a try, and if it doesn't work for you, then let us know and hopefully we'll be able to come up with a different solution.

Well the reason I mentioned it was that I enabled that as one of a number of weaks and ended up having to hard reset as I wasn't getting Texts in a timely manner etc....it was probably another setting but I couldn't be sure.
Will try again. Only other thing is that data connection on 24/7 is great for a quick browse here and there and stock updates etc...

why is that, by the way?
You haven't got Sprite Virtual Mobile installed have you? I tried it out on my HD and it sucked the life out of it for some strange reason. And it wasn't even showing up in task manager.
Is there a list of processes, services etc that we can safely remove/disable to work in the background? What say all?
glad this thread came up - my blackstone has been absolutely fine until I had the genius idea of "optimising" everything about 2 weeks ago with HD Tweak...
Now it's not HD Tweaks fault, but whatever I have changed means that it can drain a full charge overnight, and by morning its nigh on empty, i'm going to try and change it all back today, but for sure some setting I've changed is sucking juice like no-ones business.
FWIW - I havent installed anything during this time, the only thing i've changed is some of the settings - so it's not a "rogue" app draining the battery.
OT - sorry for the semi-hijack - I guess my point is that i'll have a play with the settings and see if I can determine what's eating the battery and then compare with other people.
that's fine (re: hijack) I think the two topics are closely connected.....not sure of the answer though

ta - me either - i've changed a few settings and made a note - will post if it doesnt eat the battery overnight over the next couple of days.
So,
I'm really intrigued by the Nexus one, i've been researching this thing for a bit now.
But i still have one open question, i bought a Samsung Galaxy once, but i returned it, the operating temperature was too warm for my sweaty hands.
So how does the Nexus One do heat wise? Does it get warm at all? Or does it heat up quite a bit when let's say web surfing ( via WiFi, which leads my to my next point)
So, my next point is that i will use a prepaid SIM in this phone, i'll be moving back to germany in a year, so i don't have a contract here.
So is it advisable to have this phone without a data plan? Does it ruin the entire experience if i just use Wifi? Is it even possible to turn off Cellular DATA?
I hope to hear good answers, so i can convince myself to buy this shweet and unique phone ^^
nope mine never gets hot, maybe only when charging.
could you give a comparsion on how warm it gets?
i have a zune hd, and i absolutely love it (OLED + Tegra) and it stays fairly cool, i also had an iPod touch, those 2 never really got that warm, so you're saying i won't experience a sweaty hands syndrome with this phone? That's awesome.
And to my other question about turning off mobile data, is there a particular setting that says that?
Thanks in advance!!

-yes you can turn off cellular. but thats totaly with talk also
-I believe it will ruin the experience of the nexus without data *unless your near wifi mostly*
-but Wifi is AMAZING on this puppy. things load so freakin fast. i kick my best friends iphone 3gs when were surfing on the same router.
i am next to wifi 90% of the day, so it doesn't really matter
but there's no way to just disable DATA over EDGE or 3G?
I use an application called Quick Settings which offers an option to completely turn off mobile data. I'd struggle myself on wireless only though. Sometimes when you're out and about it's invaluable to be able to look something up or check Google Maps.
I use APNdroid works really good

512 MB RAM > 320 MB RAM
Also, stock UI > Sense UI (FOR ME). I would rather get new ROM updates from Cyanogen etc rather than waiting months and months and months on end for HTC to update (example: what version are Heros running? )

makes sense, i had a thought about the delayed update cycle too, and since the Nexus is directly google's baby it'll always get them updates first i reckon.
If you don't have any APNs (access point names), then it won't be able to connect to any data services.
If you buy one without any contract it won't have any APN settings anyway, so as long as you don't add any, you'll be fine
One point though - I don't think wi-fi stay connected when the phone is sleeping (unlike GPRS/3G), so I'm not sure any background syncing will work very well.
I could be wrong about this, but when I have wi-fi on and sleep/switch off the screen it takes a few seconds to re-connect to wi-fi after I switch it back on again, so I assume it's off when sleeping. Maybe if you don't have any other data connection it will stay on?

Like acidblade said, APNdroid will turn off cellular data without interrupting phone/sms service. It also has an option for leaving MMS on if you want.
I'm on a prepaid SIM in Italy and it's an awesome app. It's free and has a widget for turning on/off data in case you are away from wifi and need momentary web access. All it does is add "apndroid" at the end of the APN name so that the phone can't connect to the web unless you want it to. Perfect for prepaid users like myself and the OP.

Bravo has less RAM than N1. Also you are forgetting that the N1 WILL be able to run Sense or even Espresso UI and FASTER than Bravo (beacuse of more RAM) via a custom ROM.
So I am at work, looking at my N1, and I'll let you all tell me if you think there is a problem...Since a full charge last night, my phone has been off the dock for 2h9m ...
In that time, my battery has dropped 14% already. The biggest culprit...the display...with 59%...despite only being on for 15m. I always use it on the middle brightness setting from the power bar. Ive lost basically 1% for every minute the screen has been on. At that rate, my phone wouldn't even last 2 hours turned on.
Am I being paranoid? Do I have some rogue program sucking battery life? Your thoughts?
Everybody says controversial stuff about phones like N1 or iPhone regarding battery life. But I can tell you from experience and some conferences I have been the following tips to improve your N1 battery:
-Leave brightness to minimum. Only at street you will need to have it at medium or maximum so you can see well.
-Use 3G or wifi when available. It will save more battery than if you use edge.
-Use push, also it's better.
-User apps like TaskManager to auto kill some application that remain open.
And last thing, if you have a new N1 the battery life will improve with the use within the next 2 weeks. Also, I'm sure you are playing around more than usual if you just got it.
I hope this help you.

Battery History
See what the figure for 'running' is, if it's high, something is stopping the phone sleeping. Should that be the case, chage the top drop down box to 'partial wake usage' and see what is to blame.

This is the complete opposite of what everyone else will tell you.
Most people say to force 2G (Edge) because it'll save battery over 3G. There are reports that WiFi will use less battery than 3G though, but not as good as 2G. Google even says this on the screen where you force 2G.
Push Email will require a constant polling on the internet. Since Android is a web OS, its probably connected to the internet anyway, but you can disable Auto Sync and Background Sync to save battery (once again, Google says this on that screen).
I agree with #1 and #4 though. If you don't want to do the lowest brightness setting, try the Auto Dim, it seems to dim it a lot more than my old Windows Mobile phones did.

Battery Drain
My phone would drain 15% battery in 1 hour just being idle witht he screen off. I dialed *#*#4636#*#* and changed the option from WCDMA preffered to WCDMA only. When I don't get a 3g signal (not often) I jsut go back to that and set it to GSM only. For one reason or another the WCDMA preffered SUCKS THE BATTERY!
4 hours of the phone being idle and only 5% battery drain! DO IT! IT WORKS!

You need to be careful of this. The point the video made is that if you download something OF SIMILAR SIZE, you will realize battery gains by virtue of the fact that what you are downloading/uploading takes exponentially less time to retrieve. The real question is, if 2 phones are both casually browsing for the same amount of time...without worrying how much information was actually transferred...one on Edge, the other on 3G...is there a difference in battery performance?
What the video said is just common sense. If I am going to send you 20 MB file and one way takes 2 minutes to download it and the other takes 10 minutes to download, then OF COURSE the 2 minute method is going to be more efficient. So you can download on Wifi where it might take x amount of time, compared to 3G where it takes 5x or edge where it takes 10x. Thus, if the file size the person is going to download is known, then of course it makes sense to tell them to wait until they are on wifi. However, many of us casually browse, on the spot, without regard to the type of connection we are on.

Thanks, I didn't know this, for the info this thread is full of great stuff...
1) middle brightness is very bright. I'm sure you can live with 25%. Display brightness will always drain battery like mad.
2) 3G power use is usually decent. The N1 has terrible RF so it might be fighting 2G/3G. That will cost you a lot of power. If you're getting full 4 bars 3G everywhere you go even underground, you might be ok, but in low reception areas, it's gonna drain your battery struggling to boost power. Bigger issue during a call too.I notice this on my Milestone. The N1 completely fails at 3G while my Milestone fights for it. As a result the Milestone gets quite hot.
3) There are sometimes apps that run in the background. Some people insist task killers aren't necessary, but lemme give you an example. Stupid Speedtest program failed to acquire my location. After a test, you can't really exit, so you just hit home. Droidforums fanatics will always repost that link to that one thread where they talk about memory and its ok to not have to kill an app. Think again. The GPS turns on because of Speedtest and it keeps trying to acquire your location. Gotta kill it with a task manager or that thing will kill you. Or a webpage. I've heard of people going to some site that keeps refreshing. Oh good luck to your battery. Make sure you close these things. Use a task manager. Sometimes Facebook or Twitter might be the culprit even if your refresh rates are awfully long. I do not understand this phone sometimes. At times I feel that multitasking/memory management on Android gets you into more trouble than if you just flat out restricted it like in the iPhone. I'm not saying the iPhone's restrictions are the way to go, but Apple knew what it was doing. There's a reason Android phones gobble power and pull data like mad even when you aren't aware. Random apps sometimes start. Facebook widget refreshes even though the app itself is set not to auto notify and to update on its own. So with so many things running loose, its quite easy to see why your battery can go down so fast.

I'll second this, I never used to use a task killer as I figured it was just extra drain on the battery but after running across some rogue programs that kept running after being closed and draining the heck out of my battery I decided to install taskkiller and set it up to autokill apps when the screen goes off.
It's really easy to setup just install it from the market then use it to kill everything then flip through your homescreens make sure everything is up and running and go back into task killer and add everything there to the ignore list and turn on "autokill when screen off" now you don't ever have to worry about rogue apps killing your battery again and everything else will function normally.

I'm sure 100% that while phone is receiving data over edge you wont get calls. I know because I had push enabled and afterwards I was getting SMS from my carrier that I have missed calls. It might say "ey sb is trying to call you" and then stop data transfer but for sure your will miss first call if someone is trying to reach you several times.
Check it out yourself.

Everybody says controversial stuff about phones like N1 or iPhone regarding battery life. But I can tell you from experience and some conferences I have been the following tips to improve your N1 battery:
-Leave brightness to minimum. Only at street you will need to have it at medium or maximum so you can see well.
-Use 3G or wifi when available. It will save more battery than if you use edge.
-Use push, also it's better.
-User apps like TaskManager to auto kill some application that remain open.
And last thing, if you have a new N1 the battery life will improve with the use within the next 2 weeks. Also, I'm sure you are playing around more than usual if you just got it.
I hope this help you.

there are a lot of people who say do not use a task killer, including google devs etc.
i used advanced task killer for the longest time, being used to needing one as a WM user before getting my n1. after reading various posts on the issue, i tested without and my battery life increased.
i use juice defender now as well to turn off the apn and wifi, based on speeds/location/etc
have it set to prefer 2g (dont get 3g at home)
screebl also setup to turn screen off when not in certain position in hand
last one is setcpu (need root for this though) underclocking the cpu (including advanced setting and profiles i have set)
lowest setting for brightness
also keep gps off unless needed
i hit about 24hr from unplug til 10% w/ heavy useage, wifi on all the time (although juicedefender handles when its on/off)
just now went to kmobs UV kernel and testing that to increase my times
i've done a 24hr test from 100%>10% based on each app i've mentioned
I think while we are on topic of battery life.. for those of you who are rooted. Here is another link that I would recommend. I used these on my HTC Dream and works great on the Nexus One. Increase your battery life 10 fold.
Your Tube: "Get Better Battery Life" by droiddog
sorry not allowed to link yet
I read on another site to simply turn off the always on in the wireless settings (not the background data in the sync menu) and my battery life has at least doubled. I was worried that my e-mail would not download or other apps would not work, but all my email still comes. The trick is that while your phone is in sleep mode it does not look for email, but once you use it the phone will get your email. Unless you MUST get your email right away, I would highly recommend changing this setting. All input would be greatly appreciated, I want to see if my good luck is working for other people. On a side note I am using Fresh ROM 2.0d.
Could you post the specific path to the setting you're talking about?
If I set my wifi to anything other than "never sleep", then once my phone goes into sleep mode I have to follow a long, convoluted, pain in the ass procedure to get wifi to work at all.
Hopefully that's not the setting you're talking about?
I posted this exact same thing in another thread two days ago. I was so stoked on my battery performance that I wanted to tell others. It's incredible the difference it makes! If you want even better performance go into Settings>Location...uncheck the use wireless networks box, and check the use GPS. Believe it or not the GPS uses a lot LESS battery life to detect your location than the wireless networks.
I'm getting like 2 whole days out of my phone now after doing these things...and that's with pretty moderate use. Hope other people try it out too.

+1
where are these options?
I agree, I used the GPS as well, not the use wireless network. I forgot about that one. Your phone will only use the GPS when it needs it, not all the time like we used to think. The exact settings are at MENU/SETTINGS/WIRELESS & NETWORKS/MOBILE NETWORKS\AND UNCHECK ENABLE ALWAYS-ON MOBILE

This will vary from person to person. It will depend A LOT on how good your coverage is in the spot you're currently at.
GPS is GPS. It will require the same amount of juice anywhere on the planet.
Cell chips are different. They are hardcoded to give more electricity to the radio circuit when the signal is weak, for obvious reasons. So if you have a cell tower in your back yard, then yeah, you'll get great battery performance relying on cell based options. If your nearest cell tower is 4 miles away, and you're one of those people that loses signal when you go into your basement, then telling your phone to use cell info is only going to chew up battery even faster....
no thanks. This isn't a fix, it's a pref change.
Fix would mean that everything stays the same and you just get better battery life.
But, good advice none the less, just not for me.

Yeah, people on the forum use the word "fix" WAY too quickly.
"Fix" means everything works like you would expect, and like it should. Around here, people use the word "fix" when what they really mean is "here's a half-assed workaround that's a complete pain in the ass, but it will get 10% of the people by until something better comes along...."....

+1 - 6 minutes and counting to receive a test / text msg, while phone is sleeping. Nice the know though, if I need to really trade connectivity for battery duration. I should test whether sms polling is tied to the email polling interval. Cause it ain't interrupt driven with this setting.
edit: i know it's not really sms polling, but rather the lack of an interrupt(-ion of sleep).
Yes, you are right, it is not a fix, but a great way to increase battery life and like I said, everything works the same. I get messages the exact same way and email will go straight to my phone once I use it.

You sure about that?
When my wife sends me a text, I want to see it 5 seconds later, not 5 minutes later.
That may not matter to you, but when you make a statement to the whole world, you have to realize that some of us care about things that you might not.
How thoroughly did you test before you decided to say "everything works the same"?
Did you really test EVERYTHING? Or did you just test "everything that matters to you"?
I used to turn off background data and stuff on my stock 1.5, and I was thrilled I could actually leave it on with 2.1 so I wouldn't have to wait for google voice texts and gmail to come in. With 2.1 I can go the whole day with moderate usage and still have 40% at least left when I go to bed. Let it charge overnight and I'm good. This is good to know though if I am out in the sticks in a pinch and need the extra battery.
maybe it's different in 2.1 but in 1.5 i tried turning off the "always on" setting under mobile network settings under wireless controls but i found that after a while the phone will fail to restart evdo upon awakening and the only way to fix it is reboot. Never tried it on 2.1 but to me between the time on without signal fix nd upgraded radio i get all the battery life i need...
I get messages right away. I just got another one, tested it with a friend and it came right away!
On a side note, messages and phone calls have nothing to do with the internet. Remember we used to get text messages and phone calls way before smart phones.

But at what cost?
That's the big question here. Are you 100% sure that you're not missing any communications, or having them delayed?
I'd LOVE to have better battery life, but when it comes down to it my phone is a communication tool. If any battery tweaks delay messages, then they're WORSE then useless, they're actually harmful.
If I wanted to use my phone as a half-assed replacement for a PSP, then I'm sure I could squeeze some amazing battery life out of it, too. But above all, and with NO compromise, I must be able to send and receive communications instantly.
That's what a phone is.

Have you rebooted while in that mode?
Yes I have rebooted and just did another test. Got the text right away. Even more interesting is I have a program called Mobile Defense which can find your phone if it is missing and that works as well since it is all done through text messages.
I have my Arc for 3 weeks.
After observing the battery performance for 3 weeks.
This is my conclusion.
1. Battery drain in term of percentage per hour in standby mode* = 2.5%
*: WCDMA, mobile data off, Wifi off, using WhatsApp
2. Some apps could cause the battery drain. This is the list
a. Fancy Widget v.1.3.0
b. Kuwo Tingting
How to check?
1. Monitor with System Panel
2. Kill all your task with a task killer. Try to scroll the scree panel with your finger very fast. Are you feel lagging? If yes, system process run with around 30% CPU.
Make a system reboot will solve this problem for temporary. (Fancy Widget v.1.3.0 caused this problem to me.)
3. Check the battery usage. If you find an apps that use the battery but actually you are not using it or just use for a while, the apps is the culprit.
Hope this will help if you have battery problems.
Please share your findings (performance and problem apps) to this thread.
Thanks!

3G on or off? What do you mean mobile data off? Then how do you use the WhatsApp?
Some of my advise, is try to always keep the brightness 0%, then use it just when really needed. The screen can drain a lot of battery.
wcdma is 3G. i check whatsapp regulary by turning on mobile data.
at home i always turn on wifi.
actually not much different if you always turn on mobile data without sync data with your apps. but if you have apps like fb, twiter try to always sync the data, it will consume a lot of power.

I rooted my arc with gingerbreak, deleted aload of bloatware and my battery is now 100 times better.
Currently had the phone idle for 38 hours with abit of usage with wifi on and battery is currently at 77%

Advice Dog says: Buy Sony Ericsson phone - Remove everything that makes it a Sony Ericsson phone.
View attachment 584718
u jelly? :trollface:
I am using a stock LT15i - my batt doesn't drain that fast.
I have wifi and email sync on, brightness = 15% and occasional sms and emails. answer a few calls within a charge/discharge cycle and still have 80% within the first 5 hours of use and 70% the next 4 hours. 60% by dinner time.
I'm very satisfied with battery.
The only thing I've noticed is that when I played Dungeon Defenders with max screen brightness up, and had Wi-Fi on, it drained like a proper ************, over 30% battery in less than a hour. Dimming the screen down to lowest and turning off Wi-Fi helped a bit, but DD is a massive battery hogging game.
Any other game or app, the Arc takes like a champ.
Also, what Belazor said is extremely true - root it and remove unessential apps.
I also installed Green Power Free + Advanced Task Killer - anytime I go to turn off my screen, I just kill everything with that funny little widget. Can go for days with that kind of usage.
When I encounter one of those guys that complain about battery life of a smartphone, I silently grin inside, 'cause it's pretty clear that the smartphone is probably smarter than such a person. With smart usage of your phone, it can be extremely efficient and excel at what you want it to do.
I can usually do some gaming for 2-3 hours per day with screen dimmed to lowest ( daytime ), browse some net for ~10-20 mins, it'll last me for 2-3 days really.

Actually, that was sarcasm.
I was saying I don't understand why someone would buy a SE phone and then proceed to remove exactly everything that makes it a SE phone - sans the shell.
Sure, part the reason why I bought the Arc was because it's sexy as all hell, but mostly it's because I like the software. If the Arc came with Android 2.1 but the sticker saying "we will totally update it to 2.3, pinky swear!" I would have dropped it from my list in an instant xD
Software makes the phone, just like clothes make the man.
People (including me!) will remove apps that come preinstalled that they don't use or want.. so for example, I removed Moxier and timescape off my x10.. I've removed a few bit and bobs off my arc too.. just saves memory and if they ones that run in the background all the time, then it keeps more memory free during normal operation.. making the phone quicker when under stress!

I bought the phone for it's camera and design, that's all =)
An awesome tip that I read I just verified to work like a charm: use the "WCDMA only" option. It consumes around 1-2% per hour when stand-by. The another thing to complement this, it's root the phone and remove the bloatware. I'm almost satisfied with my arc (9/10). Goes incredible fast. It will be 10/10 when they fix the multiTouch issue

No. I mean 3G ONLY (WCDMA ONLY). I read yesterday that If you choose the "GSM/WCDMA preferred" (third option), it will constantly check for both so it consumes a lot more power. I'm now 3G only and battery is awesome. Of course if your network has a bad 3G, you should use GSM only. The important thing is NOT tu use the third option.

It does. But this isn't about the power used by each one, it's about the battery used when the third option is selected, because the system is all the time looking for both 2G and 3G anytime the signal goes a bit low. Of course, if you download a huge file, it will be faster on 3G but take more power, but if you're not about downloading and just common navigation, you will be ok. I've been on "3G only" since 10 am (it's 6:52 pm now, so it's been almost 9 hours), and I have 81% battery. Used whatsapp A LOT during the day, made 4 or 5 calls, sent some SMS, and played some Angry Birds (0% brightness). Besides, I removed all bloatware from phone (this helps too). Just don't use the third option.
