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'm not sure if this is a common problem or not but lately I've noticed that when I unplug my phone after it says 100% charged, it immediately drops to a lower number. At first it would stay between 97 and 99, but i have seen it go as low as 45. I've tried several things like not installing the ROM until it is fully charged, calibrating the battery, and a few others but nothing fixes it. Is it possible it's just a kernel glitch or hardware issue?

Its not a problem its a feature. The phone will stop charging when the battery gets to a certain temperature. So it will say 100% but it can go as low as 90%. I have no idea why your battery goes down to 45%...thats not normal. Try wiping battery stats from recovery or reinstall your rom.
I've had a similar situation. It helped to fully drain the battery until the phone shuts off.
Wait a while, then restart the phone without plugging in the charger. There should be enough charge to load the ROM.
Then plug in the charger and charge to a full charge.
If you are calibrating the battery, wipe the battery stats only after a full charge, and then be sure to run the battery down all the way before recharging.
2-3 cycles helps.
It's strange because the charge is shown accurately when the phone is off and plugged in. Like if it says 100% while the phone is on and I shut the phone off without removing the charger, it will show the actual amount the battery is charged on the battery meter. it's as if the kernel is having a problem reading the current battery state.
Thank you both for the advice though. I was very careful to install the rom with a full charge this time..or the base anyway..

It doesn't matter what the battery is at when you flash, the "flash at 100" rule is just a precaution to make sure your battery doesn't die mid flash. I flash as low as 20%
That is a well known bug with gingerbread...yes the feature stops charging at 100 and us let drain to 95 and then starts charging again, the bug is that it Bebe starts charging again at 95 it continues to drain, so even though it says charged as Dijon as you unplug it drops to the actual percentage.
it's really random, and not everyone sees it, and those who do can't replicate it consistently, thus no solid fix has been found.
Some have said turning wifi off while charging helps, some say turning it on...
Well that's a relief. You just saved me the tedious task of fully
Charging my phone before flashing back to froyo. Darky's 9.5 seemed a lot easier for daily operations than the reoriented gingerbread roms. I had to remap my softkeys for starters, and was having a lot of force close issues with apps I used a lot, the battery problem was just the most recent headache.
Thanks for all the help. Hopefully I'll have time to start learning development instead of wasting my time fixing my phone.

Hi,
With all applications closed, data/wifi/gps/sync all turned off and no screen usage my phone went from 100% to 19% overnight (roughly 8 hours). I did this as a test after my phone would randomly throughout the day drop by large percentages.
Prior to running testing the battery overnight I put it to charge, and I found that it charged from ~20% to 100% in only an hour, which I believe is abnormally fast.
I am on the stock ROM with the stock kernel and no other applications installed.
What might be the cause of this?
Could this be a software issue (ie: software stopping the charge early or the displayed battery percentage being off)? Or is this likely to be the hardware?
Thank you for your help!
Try completely draining the battery then charging it with no powering on ( just plug it in then dont touch it) for 5+ hours

many causes are possible, however most obvious one is rampant wakelock called baseband_xmm. no definite solution, although custom kernels have dealt somewhat with it.

I have stock ROM (JB India version). I noticed similar trend a few days ago. I had done factory reset and subsequent to that, battery loss overnight is less than 1%.
You could try the same.

@rudders93 @zri best you can do now is to install betterbatterystats. it will tell if anything is keeping your phone cpu on.
Thanks so much for the replies!
As suggested, I found that completely draining the battery and then charging the phone while it's off resolved the issue
So I've never had a problem with my battery at all. I easily got 6h of screen on time and everything was great.
Recently my Nook started to randomly shut off at around 20-30 %. It "popped" and it was off. Didn't reboot either. Like the battery was dead.
I would have to charge it again to be able to power it on.
Also the stats seemed to be off. The lockscreen sometimes told me it's fully charged and whenever I unplugged my Nook it wasn't fully charged. The battery LED also sometimes flashes green/red during charging.
I only get around 2-3 h of SOT at the moment.
I tried reflashing a couple of times (with full wipes) but the problem occured again.
So my question is: Are my battery stats messed up? Does it just stop charging at a certain point because it thinks it's fully charged but it isn't in reality?
Any ideas (on how to fix this)?

It's almost sure that you battery is degrading very fast. But its my advice to re-calibrate your battery. Set your screen brightness to max setting and leave it on until it shuts down. Now don't power it on. Leave it charging for around 2 and half hour.
Now install geekbench benchmark app and test your battery.
If you heard a pop noise, the battery probably delaminated/micro-exploded. (Li-Ion's tend to swell and fail from the heat of (over)charging.)
There's a company, newpower99.com, who has a YouTube video on replacing the battery in the HD+. The battery sold for $25 US last year, but now that our batteries are beginning to degrade, they're out of stock.
I found another site selling replacement batteries for $80. (portatronics.com)
I've noticed that my screen-on time has dropped from 6 hous to 5.5. Maybe the Nokia N1 will be available and rooted by the time I hit 3 hours.

I'm having the same issues, and reading this reminded me of trying BatteryCalibration to reset the battery since my nook HD+ stock OS is rooted.
I had this problem several times before I installed CM. Usually, it happened when there was an update available, and when the Nook started to update, it factory reset itself.

Hi guys,
I keep having weird battery behaviour which led me to believe, that the battery is not properly calibrated:
When charged to 100%, the phone usually stays at 100% for a few hours depending on usage. Around 40% however it keeps dropping 1% every 2-3 seconds until after a few minutes it is drained completely and switches off.
Did anyone else notice that kind of behaviour? (Some guys on Reddit are facing the same issues)
And does anyone know a fix except waiting for a custom rom?
Thanks and all the best.

Same here, I didn't notice the battery after 40% but the phone stays at 100% for a really long time, I played Honkai Impact at max setting and it still manages to stay at 100% for an hour, mb it's software issue, I'm on 12.5.7 Global btw.
I didn't experienced that kind of issue. 12.5.13.0 EEA here.
you have to calibrate the battery.
- discharge the battery until the phone turns off
- with a slow charger (10 / 25w) charge the mobile OFF
- once it reaches 100% (1-2 hrs) wait another 2 hours.
- Power up and test.
This method usually solves this problem, it is important to use a slow charger and only use the 120w one when it is really necessary. It seems that some batteries have not been properly calibrated

Thanks, I'll try to do that with a slow charger.
After it reached 100% still keep the phone on charge for the next two hours or just wait two hours to power up?

Still keep the phone on charge min 2 hours or more (ex. When you sleep) next you can turn on

For me viper4android it's much better if you use wired headphones. I tried to use Dolby but it's not the same.
I'm on 12.5.13.0 EEA, same problem. Phone stay at 100% for hours, then when power dropped to 35-30% weird thing happened, it keeps dropping 1% every 2-3 seconds until after a few minutes it is drained completely and switches off.
Then it takes 5-10 minutes to start again
I will try to calibrate the battery tonight
Hi, I was facing a similar issue.
I have used 3 chargers. 120W (stock), 10W (samsung), 65W (Anker). I was worried about my battery life, so decided to ditch the 120W charger which was also not giving me a good enough battery life, considering its a 5000 mah phone.
Im not paid by anker or something, but I saw a major difference between SOT compared with stock and samsung charger as well. I dont know why this is working out so well, but im getting 7+Hrs SOT easily, on heavy usage. AndI have been getting consistent results from the past week since i switched to anker. I genuinely dont know why or how this is working. But if it works, it works.
Im assuming due to the 120W quick charge, the battery calibration gets messed up. But idk how to explain the longer duration of SOT on the anker charger.
Ps. I dont use 5G

yes, I don't think you are very far from the problem. I also think that charging the mobile at 120w spoils the calibration of the battery so I use it only at specific times. I use a standard 15w charger (approx 2hrs)
3 days later It looks like calibration sorted my issues. Now battery behaves as is should.
So calibration is very recommended if battery plays up
I recently purchased this cell phone, and I am experiencing this problem. I have disabled almost everything, and uninstalled blotware. Should I calibrate the battery to improve battery drain?

Please read my reply in this thread, that will extend the battery drastically.
im facing this problem with this phone as well but also something else: after the battery drops to 18-20% it then discharges very very quickly to a point where in a matter of 5-10 minutes of use it's down to 0%. is this normal or is it another one of those side effects that their trashy fraudulent scamming xiaomi battery measurement causes?
will another rom fix these issues or are we stuck with them in this phone i rapidly regret getting?
I'm also facing the same issue, below 25% to 0% it drains like a liquid, I attached the screen record

mine got fixed (at least for now) by calibrating the battery (leave it to discharge and turn off - try to turn on again until it wont - charge to 100% with phone off) i'll see how long this lasts and update
Ya i did it for now it is fixed might be a temporary fix. I'll post here if it happens again
Same problem at first month, 100 - 99 became shorter and shorter while charging cycle increasing.
