Hello,
I recently got my nexus, and rooted only two days after receiving it. I installed cyanogen's latest. I am getting low battery; in only 5 or so minutes, the percentage goes down by at least 2 percent (while using). I looked to see what may have been draining the battery, and found that the display alone was using 62% to 75% of my battery. I tried undervolting, but the display seemed to still be in the same draining range...
Is this a hardware related problem, or is this a common nexus thing?

same here, really starting to piss me off when i see people talking about 70% battery at the end of the day while my phone dies in 6 hours
Cyan?
Woah, I think this might actually be cyan's Rom.
I flash enomther's rom and i got display percentage at around 15-16% ...
I think cyan will look into this soon enough...
But for now... I guess I'm gonna wipe... :/ and stick to enom's or some other ROM...

C´mon....see my signature!
More than 10h now, Wifi on all the time -> 70% battery
This is not that bad

I think the problem is only with a few people, but I know others are experiencing this. This might be something with the "latest" nexi. But idk, it's a mutual issue, a fix should be coming
Probably you are right...
But, I would like to know, what settings peolple use: like updating wheater every hour, emails, widgets,..ham many apps are running and so on, ... perhaps connected to...sometimes people dont even know that
Edit: I got my Nex in january.
The change in the display usage percentage is just due to the way the powermanager works. Its not using more battery, its just displaying how much power it is using more accurately.
have the same problem.
100% airplane mode ON no WIFI, in 5 hours 72% battery remains . (PHONE IDLE took most of this - my G1 could go 1 month with this settings)
IN 12 hours in was 6% and with LOW use of my N1.
Yesterday I removed numbers in my battery and it was a litle better, not much but a little. (about 8% better)
I had 5.0.5.1, 2 and 3 and everyone had the same problem!
CM please take a look at this. What do you need any LOG info or something!
Have you tried wiping battery stats, then charging to 100% with it off, then booting into recovery and wiping battery stats again, then charging to 100%? The few times I've had battery issues that's taken care of it for me.
I flashed cyan again with a wipe (again), but got the same thing.
On enom's rom, I get beastly battery. I think we just have to wait for a fix for the people who are affected.

Do you need root to wipe battery stats? how do you do it?
Well I did the wipe battery about 3 times and in OS it was already green light 93% full.
I WIPED and put the power in on NON POWERED PHONE. It took 1 hour more to come to the green light . than I wiped again and went to boot up.
at 11PM i had 100% battery went into airplane mode wifi OFF.
And i did one other thing. Some of you had the battery drain issue with trackball wake. So I disable it.
7 hours of this and I got 97% - beautiful
before that I had 72% so there is a difference.
Now I have to see if the wakeup trackball is the cause of this or the wiping the battery stats.
Will eliminate one and other and keep you posted
I took my phone off the charger at 4:30am and the next day at 5:30 am i had 12% battery left. i used my phone a total of 3 times. most of the time it was on standby. i have setcpu with my phone UV and UC to try to save battery with profiles set up. in battery information 85% of the phones battery went to cell standby. Any suggestions on how to improve this?
Try wakeup trackball OFF in spare parts and battery % OFF in upper taskbar.
I have now from 100% to 59% in 7 hours. wifi ON all the time.
I have tried to wipe battery settings and charge fully with the phone off, but after the full procedure, I still get the same end result. I attached a picture of my battery usage.
Im pretty sure i saw a post online about the newer nexus's that were released having a better display. If this is true then wouldn't the phone's hardware alone be using more battery?
I can confirm I am having the same problem. I wasn't sure until I checked battery usage overnight. It used to be that with my phone on airplane mode I would use about 2% while I slept. Now, it's 9 or 10% with "Phone Idle" taking the lion's share of it.
I have tried deleting batterystats.bin after a full charge; powering off (while on charger); charging up to full again, but this has not solved the problem.
A few notes:
When the phone is idle (but not in airplane mode) it uses about 1.5% per hour (compared to about 1.1% in airplane mode)
I am using setcpu profiles to keep cpu usage right down when idle
Around the same time I upgraded to 5.0.5.3 I also started using the himem version of fastboot. And yes, if you suspect I don't know what I'm talking about here, you are quite right
For my next trick, I will try resetting battery statistics via recovery. What fun!
I've kept the cyan rom, and changed some settings to increase battery life. I turned off the battery percentage icon, and turned off the trackball to wake. I still got that the display was using a lot, but the battery still lasted pretty good. I guess there isn't too big of a problem on my side. It probably is the "newer displays" on the "newer" nexi. Maybe there really isnt a big problem
I changed now from CM to Enomther's TheOfficial Nexus1 1.8.1 and battery now works great.
I unplugged the charger at 12.00 am at midnight and with quite good use, not extremely havey but a good use I had 30% battery left at 20:00 (08:00PM) that day.
I lost only 2% from midnight to 7:00AM in my airplane mode and with Gmail check 10 min of phone calls wifi ON all the time checking web pages and showing off my live wallpapper at my work I had at noon (12.00PM) 70% battery left!
I LIKE IT!
now I'm thinking to push Kernel - .32 & .33 to see if there is any change with my battery
http://forum.xda-developers.com/showthread.php?t=653598
After resetting battery stats in recovery, I still lost about 10% overnight while on airplane mode.
For my next trick, I'll use a task killer like "Process Manager"* to keep everything unnecessary switched off overnight. Maybe I'll be able to narrow it down to an application if it's not something integral to the actual ROM.
*Yes, I know it will use up the battery too
I have had battery problems plague me for the last month, regardless of flashing, reverting to stock etc.
The following data is compared to my friends captivate, who is running the same setup as I am Continuum 3.11 and Speedmod k13c. He currently gets at least 24 hours on a full charge (thats WITH gaming and calls etc.). I can barely scrape 10 on minimum use.
At first I thought it was a rogue app that was constantly draining, but unfortunately it was not (after several trials and monitoring apps).
Next, i tried reflashing, Master clearing + flash from stock, flash at 100% charge, but still nothing.
Next thing I tried was to see if it was my battery was faulty (doubted it because it was new from original phone. Only had it for 2 months) by swapping batteries with my friends Captivate (also original battery). I concluded that this was not the problem since he was getting great battery life (if not better since mine is newer) and I was still draining.
After, I tried battery stats wiping, recalibration (bump charging) flash to stock and flash to a rom with reportedly good battery, with k13C speedmod. Still bad results.
So heres my current situation: I am running Continuum 3.11 with speedmod k13c. I have tried almost everything in my arsenal and googling but I have come back empty handed. It is NOT the battery, rogue app draining OR rom/kernal. I am completely stumped.
Heres a summary/extra details of my trials:
-Flash to stock and try again
-change batteries
-wipe stats, drain and recharge, charge for 8 hours, bump charge (recalibration), flash from 100%, master clearing etc.
- setting brightness to lowest, wifi off, plane mode when turning back on
- being anal and not installing new apps / using what rom came with
- My phone remains ice cold on standby. I know that when it gets hot, it drains (during standby and etc. but this time its ice cold)
- Here is some data: In one hour of minimal use (checking texts, replying etc.) I lose 10%. overnight I lose around 20%. In a heavy usage, 4 hours.
(note : I know that some of you might consider that barely passable battery life, but if I directly compare to the set up of my friend, its not right since in heavy usage he gets about 12 hours, which is my max per charge on minimal use)
Im hoping someone can help me with this problem, because I believe that this problem is plaguing other peoples phones as well, not just mine.
REFERENCE THREADS THAT I HAVE LOOKED AT:
This one
And this one of course
EDIT:
I recently swapped batteries again with my friend, because I recall fixing it at one point, but I had to reflash it due to a bug or something, i dont remember. But when we swapped batteries and swapped back, I seem to have fixed it. This leads me to believe that My phone right now has no idea where 100% actually is and its only charging to some random % that is NOT 100% .
This time, I swapped with him when he had 47 percent, and I had 87. After we swapped, we immediately checked the percentages. To my surprise, his 47% on my phone immediately turned to 23% But strangely, that 23% remained (the charge on 23 seemed to be holding for quite a while). But when I recharge, it charges WAY too fast (10 minutes of charging = 40% in total from 23%? B.S.!!!)

I guess thats happen when you flash new rom or kernel or modem...you need to wipe battery stats to fix that....

I wish it were that simple =( I already tried that via recovery. Unless the recovery method is bugged and not actually wiping the stats. I will manually delete the battery stats and retry, but I dont think it will work.
im just reporting back that manual battery stats wipe did not work =( Any help please? I am absolutely stumped
sorry to triple post but I thought I should ask something else:
Would extracting the batterystats.bin from another captivate and using that one work? (assuming i set permissions correctly)
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
The thing is, that I'm having this issue for a while now. Battery drains extremely fast both on stock, stock + ext4, cyanogenmod, no matter what. Now I decided to install the stable version of Darky 10.1, but it's just about the same... It's like it drops 2-3% percentages in couple of mins (~10m). I'm using my phone at minimum brightness (btw, display uses 9%! only of the battery), no OC/UV, no animations, only 2g, no wifi, no gps, no account sync, so I'm like really trying to get more...
Okay, and here comes the thing: It used up 70% of the battery in less than 5 hours, and the battery stats looks like this:
Android OS 62%
Android system 10%
Display 9%
Cell standby 5%
Phone idle 2%
Dialer 1%
Dead Rider (just a game..) 1%
In my opinion, everything looks great, but the Android OS. Now what the *** is that, that this crap uses 62% and growing ?! PLease help, thanks!

Hmmm what apps r u using ? how many apps do u have installed ?
Did u buy ur phone used or from new and if u got it from new did u do the over charging for 16 hours or more ?
android OS is a huge problem for battery drain with a few causes and plenty unknown.
to fix it completely will require some skill full people from a closed source.. Download an app such as juice plotter or similar to find out a cause of the battery drain.
there are things you can do such as undervolting for extra battery life.
But the best thing to do is type in Android OS battery drain, in the search bar and have a good read up. i had this mega battery drain a few weeks back but i have it under control now

Charge your phone till it reads 100%, reboot into recovery and I think in Darky's Kernel under advanced you will see wipe battery, do this, boot your phone and let it charge back to 100%, then unplug your phone, let it die to 0 and charge again.....something weird is happening because it shouldn't be that bad....if the above doesn't work and you can rule out apps possibly you have a bad battery?? To rule out apps, wipe everything and do a fresh install of a stock ROM if it still drops then i would say it's a bad battery, but try what I suggested first (wipe battery stats)
The last maps upgrade causes bettery drain....
how to slove this problem?
Hi!
I have the exact same Problem..some say this is a bug in the gingerbread versions and can only be solved by samsung...is this true? Any ideas?
Well, I've had a pretty big read-up on it, and tested it myself, what's more tried out other things too. So I came to a conclusion, that this is absolutely true. It's said to be enough the 'freeze' the apps that cause this problem, but it's just not true. With frozen, they somehow still did it. So here's what I've done, and it looks like solved (far not as good battery life as 2.2.1, but still, at least acceptable...):
- format internal sd card
- removed the suspicious apps (msyncml, syncml, it depends on your rom, the important is, that it has "sync" it its name, and NOT account sync!)(I also removed Samsung account, and everything **** that I didn't need)
I'm having BUJV9 on right now with newest FuguMod and it looks good.
It does not mean Android OS is using 62% of your battery over the time in question .
Its a measure of what has used the power not the power drain on the battery .
Though useful on a heavy drain as your figures show display off OS using a lot but what time span at the top of your figures ..
I would guess from figures posted you have something working away in the background . A factory reset usually cures that problem .
Or find the culprit .
PowerTutor from the market may help .

I was having the Same Problems with Battery Drain. (Dropped 70% in 6 Hrs.)
It is related to 2 Services on Gingerbread.
Software Update & Samsung Account.
Clear Data and Freeze Programs using Titanium Backup and Your Battery should be back to Normal.
Huge drain on battery SGS i9000 android gingerbread v.2.3.3
I did like some other users have done I quess!?!
I upgraded via KIES from earlier version of android. After upgrade I did a reset to factory settings, but didn't set the "Format USB storage".
I installed a few programs and used the phone for a few days. After short time of usage I noticed that the battery drained really fast. Like 20% within 1 hour or so. Normally 20% battery drainage happens in a day with little use.
Then I thought something must have gone wrong with the last upgrade. Many time the tip is to clear the phone again and this time I set the "Format USB storage". It worked. Now the battery drains about 30 percent during a normal day with little use.
Since I have a backup of everything, I just installed the backup so the phone is back to normal again.
I hope this might lead to solving battery drainage issue for other users or at least and idea of what could be wrong.
First of all, I do not trust this solution, but it work to me
Solution is simple, remove your memory card from the phone
That is all
After check, found that the scan media always running to scan the memory card
This might deal to corrupted card
People say backup the data from memory card, format the card, put back the data
I haven't try format the card
But after my phone remove the card, now already 13 hours, I still have 82% and I did few phone call as well
there is an app by the name of battery calibration...follow instruction from within the app and it should solve the problem of android OS drain .. i shifted from darky 10.1 to MIUI 7.7 and 100% to 30% in 3 hours with normal usage and no wifi .. after this app battery lasted for two complete days ... so try it
There is another MORE SERIOUS BUG in ALL GB ROMs:
http://forum.xda-developers.com/showthread.php?t=1134741
After full charge in GB, phone start using batteries ONLY instead of CHARGER ONLY like in Froyo and lower version builds.
Samsung folks goofed up BIG TIME by making phone use batteries instead of charger after full charge while stopping the charge cycle. Because of this OS thinks its running on CHARGER (or USB POWER) and shows batteries as full charge when in reality it runs on batteries after full charge and will eventually make the phone dead through full discharge of batteries.
You could test this by keeping the phone connected to the charger after full charge for a prolong period. When you disconnect, based on the usage during that time, the batteries will instantly show lower charge than around 100% (could be close to 0% as well depending on usage after full charge if you disconnect charger before phone going dead at 100% drain).
Did you flashed Darky in 100% battery? The tutorial suggest you to do that. You can try to wipe battery in recovery mode.
a few days ago i flashed stock jvs. and applied cf root.
now i'm facing some weird things. battery lasts only like 12h. and when i go to battery stats in "about phone" the "on battery" time says things like 1min, but the longer the phone is on, it gets longer, like 2h ...
today i tried to fully load it and wipe battery stats.
didn't work,
now i've applied semaphore. and still shows weird things. and it doesn't seem as if the battery would last longer.
didn't find a thread with this problem, only the "official" battery bug, when the percentage changes within an hour about 20% a higher...
maybe so knows?
When you say wipe battery stats, did you do the entire battery calibration procedure? I find it's most effective to wipe and charge phone overnight while it's off (Like the first charge you do when you first get the phone)
i did the calibration like it is said in another thread:
fully load battery,
go to recovery, let it plugged in for further 5-10min
unplug,
wipe battery stats
reboot and let the battery be drained until it turns off automaticly.
but still confusing...
never had this befor, on stock 2.3.4 and cfroot, normal information like 2d 3h ... etc.
