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...

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
So I was running cognition 2.4.1 for a long time, and my battery life was awesome. It would barely go down at all if I didn't use it, and would make it through the day with about half to spare. On normal days I unplug at 630am and at 5pm it would be at ~70% (if i didn't really use it at all). Even if I did use it it would still last a long time.
I finally decided to flash a new/different rom and thats where my problems started. I flashed Assonance 5.0 and the battery life got worse (at 5pm i was at about 45%) so i just assumed it was the rom and that cognition was better on battery life. So my next flash was back to cognition (a newer version, b7 i think), which improved battery life, but it was barely noticeable, and was no where near what it used to be. Next I tried pheonix v1.5 and that was probably the worst yet, as my phone almost died by 5 oclock.
Finally I decided I would go back to cog 2.4.1 even though it was outdated. I figured this would solve all my problems. I was wrong as my battery life is absolutely terrible right now. At one point yesterday it drained 12 percent in 30 mins.
Something else also happened yesterday. As it was almost going to die i plugged it into my car charger for about 10 mins. It was at 15% when i put it on and 19 when i took it off. After that my battery life was almost normal again as it only drained 4 percent over the next 3 hours. Later on that night I charged it back up to 50 percent and about 10 mins after taking it off the charger it said it was at 5 percent. It stayed at 5 percent for the rest of the night and did not die ( about 4 hours).
Theres definitely a problem and I know it was to do with the battery reading. I think i just need to reset the battery stats.
FYI every time i flash a new rom i always flash back to stock jf6, make sure its 100% battery, wipe data and cache, etc etc etc. so im not sure why this is happening.
I also tried wiping stats through clockworkmod recovery, but i dont think it really does anything.
The proper way to wipe battery stats/recalibrate your battery:
Charge up to 100% with the phone on. Disconnect the charger and turn the phone off. Connect the charger; you're now in charge mode. Charge up to 100%, disconnect the charger and turn on the phone. As soon as the phone is on, turn it off. Connect the charger to put it into charge mode again, and charge up to 100% again. Some people also say that before starting this process it's a good idea to kill the battery completely.
That is how you bump charge, or recalibrate the battery. After bump charging is the best time to wipe battery stats.
I can't find batterystats.bin on the phone to delete it. Is the only way via terminal mode or Clockwork?
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.
hello,
i've had my SGS for a little over a week now. from day one i noticed battery drain but i thought it was normal for a new device. i flashed darky's 10.1 extreme on the second day i got it because it was very slow and had a lot of bloatware ( i wasnt very patient and i flashed at 95% or 96% battery), the drain was still there. i let it go through a few recharge discharge cycles and no improvement, so i used an app from the market called "batterycalibration" by marosige, no improvement and it the reading would drop to 99% or 98% after taking it off the charger.
i did a little digging and discovered i had the android os bug (was over 50% usage usually) so i used titanium to wipe software update and samsung account, and froze the first, didnt help by much
i then flashed darky's again at 100%, and now it still reads full charge after removing charger and android os bug i gone (reads 4% system and 4% os), but drain was still there. i emptied it to the point it couldnt turn on anymore then charged it from wall charger while turned off to 100% while i slept
i woke up and tested it by playing a game (Blastmonkeys) for like 20 mins and the battery went down to 90%, that was less than 2 hours ago, and now its at 87% and it was completely idle
notes:
my brightness is turned all the way down with no animations but display reads 54%, wifi is usually on when im home but battery stats show 6% wifi so i dont think its a big problem
also, the device was bought locked in france by someone else and im in egypt, so i dont know anything about warranty..
im sorry for the long post but i tried to be as detailed as possible...
hello,when i upgraded my sgs to 2.3.3 i also got battery drain and android os was consuming hell lot of cpu about 70%,..,.,then i flashed 2.3.4 jvp i didnt get any battery drain in that firmware then i upgraded it to 2.3.4 jvq this also donot have ny battery drain..,,.i recommend u to flash it and try it once
will try, but isnt darky only compatible with JVH? what happens if i change to JVQ?

As far as I know, the percentage not being 100% after unplugging is normal. To prevent wear on the battery, the phone cuts the charger after reaching 100%, and restarts charging when it reaches ~95%.
I don't think a 3% drop in battery over 2 hours is uncommon. Wifi and data connection will pull a lot of power if on, even in standby.

Normal, this phone drains about 20% battery per hour of screen use, slightly less when watching video.
2-3% drain over 2 hours is also pretty normal if you have wifi/sync on.

Hi All,
I'm a new registered user, so I can't put this in the developer forum yet.
I noticed a problem where I was losing battery power quickly, so I foudn a posting that said to do a "super" wipe. This was to one click recovery to stock, root, bootstrap, then boot into recovery to wipe cache, data, dalvik, format /system, wipe cache, data, install theory ROM 1.7. after clearing dalvik the second time, I threw in a "clear battery stats" for good measure.
What I noticed was this: prior to attempting any of this, the phone reported to be 96% to capacity and said it was "full" so it wouldn't charge any longer. After doing the sequence above, upon initial boot up, the battery was now reporting 88% and was charging again.
It would seem like the mechanism for reporting the battery usage is flawed in some way.
I am running a few days of testing but the calibration methods are to drain fully, and charge (while device is off) to 100%, unplug and before turning on, charge additional. Before my full charge read 95%, on 1.7. I did the above and now it read 100%.
From the beginning, here's how my battery life was:
Day one: full drain with performance mode, I received 8-9 hours. Used maybe 60 mins of voice, email sync w gmail and touchdown, sent about 100-150 texts. Watched 2 episodes of the community streaming from zumocast on 4g radio all day, used Pandora a few times.
Night one: night time saver mode, this is where I discovered my full charge was only 95. My night time mode activates at 10pm, my "full charge" completed at 7pm, used Pandora
On the ride to the gym, had minimal texts, email sync, twenty min phone call, 4g radio on. Went to bed at 10pm left phone idle, no charge. Woke up at 630am night time saver ends at 5am, device reported almost 12 hrs idle time, 40% battery left. Pandora to work, 4g only, synced mail, browsed YouTube, Facebook, no calls. phone full drained around 1140am. So almost 16-17 hrs on one charge, but the high light was 5 hrs from 40% battery... Last to note, I never turned off blue tooth.
Currently, after full charge 100%(not like previous 95) I'm at 1hr26 mins and at 85% bat...same usage, same battery mode
Ill get further results soon.
Update: now at 55%, 3:55hrs on track for about 8-9hrs ... Not using app killers to add or any battery apps. Problem seems sporadic but I'm going to try to run full battery to full drain on performance mode to optimize..in my past experience Droid 1 and Droid x, over time the battery adapts or the phone adapts to the battery usage ... Could be a myth or fantasy ...

Thanks a bunch for the info. I am in the process of doing the full drain right now. Hopefully, it will show some results.

Our phones read fully-charged at 95 percent, but if you keep it plugged in it will get to 100 - it just takes a good while.
There's a trick to that. Yank the back back cover, pull the battery, and unplug the phone. Plug the phone back in and wait for the "missing battery" icon to show, then slide the battery back in. It will initially read 5%- wait for it to charge to full, which should take 10-15 min. Repeat this process until the status reads 100% charged within a few seconds of putting the battery back in. Reboot into CWM and wipe the battery stats (or use the battery calibration app that's on the marketplace, if you don't use CWM) and you should be seeing a batter that's not only noticably more accurate in its charge level, but also charges more completely, resulting in somewhat better longevity.
You want to drain it fully and let it charge back up fully at least once after this process for best results.

This is a good trick, one I was taught by juhde. I used it on my x2 to great results.
However, I can't get it to read on my bionic. I get the '?' but nothing after I reinsert the battery.

I find it only works when I unplug it and plug it back in just before inserting the battery. It sometimes also helps to hold down the power button for a few seconds with both the battery and charger out in between 'bumps'.
my fix
I have flashed every update since the first post and had battery issues starting around 1.5. After reading through the dev thread a bunch it seemed as the when performing wipes, they did not come out "clean" after one wipe. So I started at one wipe of each (factory reset, system, cache and dalvik) and the problem persisted. I then did 2 wipes of each, then 3 and 4. after 4 wipes of each all my issues had been resolved. not sure if it will work for everyone but it was the turning point for my device and might be a good starting point for anyone who is as annoyed as i was. good luck!!!!
Update:
Was able to repeat 17 hrs with custom settings: data off @30 min peak/off peak. Blue tooth was on the entire time, cell idle and Bluetooth were 30% consumption each.
Right now I'm in full performance on track to do 9.5 hrs. I've been playing Pandora for an hour every other hour, and did not kill its process.
I think the most practical usage is to cut data when not used for 30 min, I couldn't imagine anyone on their phone doing multiple things for 8+ hrs STRAIGHT. I'm running unleashed 1.7, no radio problems and no slow downs.

My brother has been getting twice the battery life that I am getting. The only difference is I have rom installed, and he just debloated. I have a switch out extended battery coming from Verizon and if that doesn't work I may just drop back to stock debloated.

And your battery is drained? Or at a certain percentage?

I think I have a faulty battery, I can't last 5 hours on a battery anymore. I'm going to go to VZW and see if I can pickup a spare and test that one.
This rom has absolutely nothing going for it. v1.7 and $6 will get you a cup of coffee from Starbucks. I have never flashed to stock as quickly as I did with this rom, since my first smart phone. Is this guy/team the only Dev with a Bionic??
Downloading/flashing on the fly (streamlined) is great however, what are we going to flash folks? 1.8??
Yes I know theory is only playing the hand he was delt but its clearly time to fold.
This makes me nervous.
For the issue regarding battery life..flash back to stock. Wait for the next developer.

Yeah? And what was the issue you had? ANY ROM you flash will nuke the battery stats and need to be recalibrated. Simple as that.

Sorry, yes it was at 5% when posted that, and that was right before my car ride with Pandora playing through Bluetooth.
The end time was 10hrs 35mins.
Since then, I have done a 4x complete wipe, cleared previous traces of unthrottle and flashed 1.7 again, disabled automatic restore apps while synching with google. I used the battery calibration app from the market this morning and have set custom battery management to turn data off every 15 mins of non use. This is practical since the power boost script shortens the time to speed up, so data on/off shouldn't affect performance. I'll update at the end of the work day. Currently at:
85%
1Hr 21mins
Maps 43% consumption (I'm adding GPS on all day in addition to blue tooth all day)
Cell idle 19%
Blue tooth 18%
Phone idle 14%

I just want to add, I'm absolutely loving this ROM. I would advise to check your steps if you are experiencing problems, and as always, keep in mind that its an ongoing development.

By your justification you are not getting normal/average battery life.
You are disabling data and your cellphone when not in use just to get close to average.
My battery drain has been pretty bad.
I have done all required steps (multiple times) but it still seems like the phone is just flushing the battery out of it.
The best life i have gotten is when (the other day) I was working from home and completely forgot about my phone.
I left it unplugged and after about 8 hours (of literally ZERO use no WIFI) the battery was at around 36%
Its like its pumping it out at full blast no matter what.
Note: I have all powerboost mods installed.
I just flashed back to stock, have the same apps and still getting the same battery life. I am actually getting more network disconnects for some reason, however common sense says that has nothing to do with stock rom or DT rom. Its a driver issue that will be getting resolved in Nov (hopefully) . Flashing back to my sexy DT rom tonight, with a full wipe.

I don't really understand what people are trying to solve.
Your problem is you left your phone on performance mode and it drained your battery. That's like leaving you car lights on and expecting it not to drain the battery. I'm exhibiting extreme heavy usage vs normal practical usage and how the ROM does *not* affect it negatively relative to your daily usage of the phone.
In my normal day, I would not have bluetooth running all day, which from my above data consistently drains 30% of the battery. Bluetooth is only used when I'm in my car which it connects to the car audio for phone and music. In my normal work day, I would not have GPS running all day, which from my recent post is draining 43% of the battery. In a normal week, I would only need to use GPS to find a unique restaurant that maybe I haven't been to or in an area I am not familiar. The main point for the contribution in this "battery investigation" is that I am not experiencing any radio loss, connection failure, or system lag by having Data shut off.
I really do not see the occassion that anyone would ever use their phone heavily for 20+ hours straight. Or even more than a movie's length straight. I could think of possible arguement points such as hiking and needing it to last for saftey/emergencies -- but why would you have it full blast on performance? Long car rides -- but if you are doing an 8+ hour drive, don't you plan on having a car charger? I just don't get what people's frustrations are. I do understand the problem that people's battery tick abnormally which is a fault of either the device, a defective battery, or lack of following directions when using the ROM. Again, the ROM is a development, and no one is forcing you to use it. It is actually quite nice to test, run into a problem, report it and have it fixed within days/weeks instead of months or never like the stock.
I guess I've rambled into a rant, but I'm merely providing my own experience in details so that people have a general feel of how the battery is and if my usage is similar to theirs.
I'm not claiming to have average/above average battery life, I'm justifying that this has not affected my daily use of the phone for everything that I use it for (being connected to work, being socially connected, and games/movies/music).
