My N1 eats battery like mad. Lost 30% in 2.5 hours with light usage: no calls, no wifi, gps or data. Just reading a document on the phone
I searched and tried this: drain battery completely, charge phone when switched for 8 hours straight but still the same :/
This is with stock Rom and the many of the custom Roms
The phone eats a lot of power trying to connect to a cell tower if the signal in your area is weak.
Mine was doing this and changing the network to GSM (prl) did the trick.
Is your area bad in coverage?

no the area is fine, London Area. Please explain the prl trick
yea mine eats crazy bad, but i always have gps/data running and decent amount of txting
and apps that use and stay running on the Background kill battery too (Tikl)
The answer is froyo with exchange mail pushing. There is a problem with the way it obtains/verifies SSL certs and it cycles the CPU endlessly. It makes the phone get crazy hot and eats the battery. I've had to completely disable exchange email to use my phone with 2.2.

Links are not against the rules, you will be allowed to post links once you have more posts, it is XDA's effort against spam and it works pretty well.
Back to the topic, it is possible that your battery meter is not updating properly. It may say you have 30% but then suddenly you drop down a lot.
Also, first try charging your phone all the way, let it charge for an additional 10 minutes after it says it is fully charged and then wipe battery stats and see how that goes. Wiping the stats will delete the files that are related to battery stats, it is useful when you are trying to recalibrate your battery if for example it says you have 9% and then it just shuts off.

Draining should not really matter, it is not like the old style batteries. Someone may disagree with me though. Why eight hours? And it shouldn't matter if it is on or off. If it is on and you look and it says fully charged, leave it for another half and hour at least. Then wipe battery stats and see what happens.
i did let the battery go at 4% once then wipe batter stats but no luck
My battery is still draining insanely
I followed this guide http://www.villainrom.co.uk/vBwiki/index.php?title=Calibrate_Battery a few months ago and yesterday but no change!!!!
Reading documents drains a lot of power, having white all over the power-hungry screen for a long time.
3 hours, 25% - nothing unusual.

That's a bad guide, letting the battery drain completely flat is one of the worst things you can do to a lithium ion battery. It kills off the capacity.
Charge battery full (prob only take 2 hours), turn off phone charge another half hour. Still plugged in boot into recovery, wipe battery stats.
These batteries have no memory effect, so draining battery does nothing

Im on CM 6.1 with latest Radio 5.12..08 no task killer and battery seems worse. lost about 12 % in an hour with moderate usage
I recently installed Serendipity and made sure the battery was at 100% while doing so (and deleted the battery file). I'm waiting for the battery to drain before I plug it in. Am i supposed to let it charge all the way again? Also, is it safe to reboot the phone while it is draining the first time? I want to install something using clockwork.
I'm being careful about this because cognition would report 14% battery life after 33 minutes of display usage and display eating up 96% of my battery....

There's a complete thread on this, I suggest you look it up.
After you reset your battery stats, it is suggested to do a few full battery circle (use til dead, full charge, rince and repeat). You should be fine after 2-3 circles.
Note tho that it will not improve your battery life. All it does is a attempt to tell your phone what % your battery life is exactly.
For your fast drain, I don't think it has anything to do with your battery calibration or your ROM. It's most likely a app (or a few) that are draining alot of juice or that are running w/o realy being needed. (Check your running services.. make sure you know which one to stop and not to***)
Also using a app/widget like advanced task killer can help your battery life as it will stop every app running with a simple touch. I suggest doing it anything you're not using your phone.
One last thing, display eating 96% of your battery is normal.. it's not telling you it's using 96% of your battery. It's telling you that during the time your phone as been unplugged, your display use was your main action.. probably cause you didn't make many calls or anything else.. Display is just about everything you do with your phone so it will always have some high numbers like that.

Yeah, I've seen the thread before but forgot about it. Thanks for reminding me. And my point about the display was that it was on for such a short amount of time, yet still killing my battery.
I am now down to 30% or so after 3 hours or more of display time after calibration & rom switch- and I was streaming music through WiFi and using Bluetooth headphones. So it it seems like it made a huge difference =D
Thanks
I'm having like 13hours to 14hours of battery life..Running stock ota 2.3.3..is it normal for such a battery life?(when my phone is fully charged right after I plugged out the charger,my battery drop to 94% to 96%is it normal too?kindly advice..thanks..

My battery indicator also drops from 100% to 96% a few seconds after i take out the charger. But after 2 days i stille have about 15% battery left.

My battery life increased after upgrading to gingerbread. I can usually go through the day (15 hours) with 3g always on, twitter and fb sync on, with light gaming and surfing of the web, 75% brightness.
My record was 2 days 9 hours with 0% brightness, no 3g, only wifi, no gaming, twitter and fb sync on.
For your percentage problem, you can try draining your battery, then when the phone shuts down, hold the power button to switch it on again. Start up an intensive app like a game to further drain the power. Do this until the phone does not start up (no bootscreen), then plug into the charger and charge overnight. DO NOT turn the phone on during the charge. When you turn on your phone after the overnight charge, it should read 100%
I am not too sure what triggers this, but its likely due to battery memory or something, although this should not be happening for lithium batteries. Maybe its a software fault. Do this every month or so to hit that 100% indicator. It is not advisable to do this all the time as draining the battery completely MAY damage the battery over time. Cheers!
How did you manage to get pass 2days of usage?

Hey,
I'm also having the same issue. Off the charger, BANG! 96% or so, sometimes more. My phone will be at 90% after like 3 texts. Its only had 5 charges mind you, I know there's a "conditioning" time but still, is this normal? I can almost say a text is a percent...my 3gs had more batt life after 1yr... now that's saying something...haha
I can almost watch it drain with the screen on...like 60 secs is a percent or 2...not cool...
Maybe I can do the "Desire Battery Calibration" procedure after a few more full charges...might make a diff...what do you guys think? I may be jumping the gun here...
Thanks in advance.
I remember someone said modern phones are designed not to keep on charging after reaching 100% and resume only after dropping to certain level, maybe 9x%. That could be the reason why I see different percentage left every day I unplug the phone in the morning. But my last Hero always show 100%.

That sounds right, because it drops from 100% to 96% after a few seconds, and its direct from 100 to 96.
But if you put the charger back it taks a couple of minuts to get from 96% to 99% and about 10 minuts to go from 99% to 100%
As far as i have noticed, this was the issue with X100 too after 2.1 update-
Once connected to the wall socket, the phone charges to 100% and starts dropping.
it does not charge again unless you reconnect the charger.
till the time it is connected, it will display as 100% but once you remove it drops to how much ever time has been spent since it reached 100%.
why that happens, i really don't know.
Ideally the phone should continue charging if the level is below 100. anyways....
about the battery backup, i think 13-15 hours is quite good for a phone with this display and capabilities.
with 3g, a little gaming, surfing, chatting etc. this should really do.
in fact, post the 2.3.3 update, the battery life has definitely increased.

So you think that having a 13hrs ++ battery life is good enough?More advice please..thanks..

I am on a VzW Inc2 w/ Froyo so not sure how applicable any of this is for you guys...but anyway....
My battery life is fantastic. I too see the 100% down to whatever after unplugging - I am pretty sure this is like others have said; once it reaches 100% during charging it stops charging and does not start again until you unplug and it re-plug it in. I know in my case charging from dead to 100% only takes like 3 or 4 hours. So if you are plugging your phone in when you go to bed it is probably hitting 100% after 3-4 hours and then the rest of the night it is draining down...
I have found JuiceDefender Ultimate and JuicePlotter to be huge helps to me in decreasing battery drain (JD) and understanding what uses the battery (JP).
Also just going into settings, About Phone, Battery, Battery use - this helps understand what is using it.
*Note: JuiceDefender Ultimate can create more problems than good if you are not willing to take the time to learn/set it up.
Prior to using JD and JP I would generally make it through the day, sometimes have a bit of power left over. After using these I always make it through the day, and sometimes through 2 days.
But let's not kid anyone - what JD does you CAN do manually...but more than likely wont or will forget. So for anyone that doesnt want to use JD, do you leave your WiFi on all the time, or do you switch it on/off? Leaving it on all the time drains battery. When WiFi is available, do you use it? I have found WiFi on this phone to use a lot less battery than 3G.
Probably my favorite function of JD I have it disable 3G and WiFi when the screen is off (for getting emails, updates, etc... you can set a schedule where it turns it back on during intervals or whatever).
Also I like the WiFi Location setting - you can teach it where you use WiFi and it will automatically turn WiFi on/off based on your location.
Anyway - my guess is if you are having low battery life, either you are using the device a lot more than you think (voice calls use a lot of battery), you have things syncing too often, or you are leaving radios/etc... on all the time that do not need to be on.
I tried to take the charger out at the same time the battery was on 100% and the LCD light went green.
Then the battery stayed at 100% for about 11 minuts and then went down to 99%.
After 3 1/2 houres the battery is at 95%!!!!!!!!
Bagground Data is enabled.
3G is active.
I have mail check every 15 minuts.
Screen brightnes at 40%
Weather update every 1 houre.
I don't use Facebook, Twitter, Stcoks and News.
I don't understand the battery in my IncS...
You guys know that these batteries don't have memory right? So when you charge doesn't matter, your phone just thinks there is that percentage of battery, do a full drain once and then it should back on track. Also, these batteries never get charged to 100%, its a safety precaution or something of that sort. They hover around 94-96% which is why the phone drops down to that area in what seems like a short amount of time. The fact that the phone says 100% when you unplug it is for effect. I used to always think I had battery problems, just stop being so worried about the battery and you'll notice an improvement. Hope this helped.

Also draining them completely flat, as in device won't power on, is the worst thing you can do to them
It sort of kills off a little of the capacity, every time you do it
So to the bloke that recommended it, no it does more damage than good

I'm finding turning to GSM only helps massively. I mean, so it should but I was hoping I didn't have to do this all the time, like I had to with my 3GS... And its a pain in the butt having to change it.
Still cant find a widget that will do it for me...not mobile data, ACTUAL WCDMA-GSM and back...
On the side, if anyone knows of one, please tell! haha
Thanks

I tell you is true, and i don't understand i either!!!
Most of the 17 houres the phone was only in standby and i only read mail twice.
I guess its just a fantastic ROM that Mike1986 has made with no Sense ;-)
I can get a day and a half out of my IncS with heavy use on a pretty regular basis. Set brightness to automatic, switch off unnecessary auto updates, GPS, bluetooth, and keep volume down or off in games. My screen timeout is 1 min (reduce for longer battery life), and I have always on internet switched off. I generally leave my Wi-Fi on a lot by mistake but don't find this to affect things too much really.
You will get 96% a lot after a charge as it is bad for your battery to stay plugged in when it's fully charged, so the s/w on HTC phone switch the charge off for a little while so it runs down a little and back up again. I had Hero before and that did this as well.
juice defender ultimate is excellent in my experience.
i had it set to switch on data every 5mins for 15secs to receive notifications and do updates (i have quite lot syncing - twitter, fb, sky news widgets x2, weather) and i would sometimes have gotten 30 hours out of the phone (ie. i wouldnt have charged it 2 nights in a row sometimes), but always easily 1 full day.
im getting sick of having to use JD though, because i figured something HAD to be wrong as my battery would drain in maybe 5-8 hours without JD which I just dont think is good enough and so could not be how its meant to be.
i then read about some people having problems with cyanogen rom battery drain, and that if you switch off android market notifications, it solves it.
so i tried it, charged my phone to 99% again and im now at 82% after 5 hours 10mins, which means if i keep using the phone at this rate, ill make it 25 hours - which is more than good enough for me. (~and i still have all the same stuff syncing as before, except market notifications~)
also i have wifi set to never sleep, so its always on. (its my ideal that everything that you buy the phone for should be able to be kept on 24/7, eg data, gps etc always on - so i keep them like that. bluetooth i dont use though - if i can make it through the day on a charge with decent use, im happy)
try it.
im calling BS on jkolner btw - pics or it didnt happen
Hello all,
I'm having a weird battery problem and am not sure if it is software or hardware. Basically, I have charged and it will last about halfway through the day. I'll look at it and between 50-55% of battery life it will turn off and go dead. I'll turn it back on and the battery is at 0% - no warning or anything. I have to then charge it back up and it seems to take a while from 0-25% and then it will skip to 90% and finish charging to a 100%. I've tried several different roms and all are giving me the same problem - currently on oxygen 2.3.7
How old is your battery, and is it a stock battery?
You may want to calibrate your battery. There is an app on the market that is specific for the N1 and instructions for it can be found http://forum.xda-developers.com/showpost.php?p=9583271&postcount=340
It isn't the easiest thing to do, but if you do have a decent battery (some cheaper knockoffs don't have support of figuring out your battery age), it can get your phone to properly detect your age of your battery and show the correct stats for it.
As for it dying half-way through the day... have you checked to see if apps are chewing up your battery time? If they aren't, it may be time to get a new battery anyway.

It is the stock battery I got when I got my phone in May of 2010, so I can expect to be not as a good as a new battery but it's bothering me that i can't have a an accurate reading on how much battery I have left. I feel like I have half a battery left and then all of the sudden it will die. I'll try the calibration and see what that does. I don't think its apps because I've flash and reflashed my phone and never have many apps as a result
Hi guys,
after flashing the starburst rom and over clocking and several tries to calibrate the battery my battery is still draining a mile a minute. I used the battery calibration app....have let the battery fully drain and charge at least 5 times now and I still can't get back my battery life!
I'm thinking the root of the problem, well...when I go to settings than battery use it says the screen is using between 70-80% of the battery...I am assuming that what is sucking the life out of my battery but I have no idea how to fix it. my screen time out is at 30 seconds...brightness is almost as low as it can get. ITS DRIVING ME NUTS
I am assuming I calibrated the battery correctly cause it does not drain at all when the screen is locked.
please, any help or suggestions would be greatly appreciated, I am ready to rip my hair out!
I just opened battery calibration app its at 70% 4mv isn't it supposed to be like 4000mv? or is just abbreviated?
I just flashed a new rom and still having the same issue!
trying to calibrate the new rom using battery calibration and its barely charging...been stuck on 61% 4mv for about a half hour now..
is it possible that this problem is being caused because I installed the roms with ROM manager and not CWM?
I apologize for what questions may seem dumb...I am a noob....but i have searched relentlessly for answers on this specific problem here with out finding much yet.
disregard that last question..lol..u can see how badly this has my brain turned upside down
