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 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.
Dear Android Community,
Overcome-day to all!
I've upgraded to "Overcome-Jupiter" 3 days back and though admittedly the new ROM is smooth and fast I believe am noticing some irregularities on the battery.
I have a question and situation, wherein in battery statistics is is show that "Display" is using around 96% of the batter, all other task including the "Android system which is only 2% is for the remaining 4%.
Furthermore for a full charge, am getting around 14-17 hours usage on the batter.
I've done a "battery wipe" and have done two discharge cycle.
Any other Galaxy tab7 user here having the same issue, your comment, suggestion and recation on my query is greatly appreciated.
Thanks in advance.

As for display that is normal since Froyo especially with heavy use, the beast display consumes the battery more than anything. As for the battery life if its on moderate to heavy use that seems quiet normal even good actually (remember official stock firmware gives you 7hrs on heavy use). Finally read the tips and tweaks section on our website for more info.
I have heavy drain on the battery after upgrading from Hermes to Jupiter. (All apps and setting being similar)
I can get only close to 5 hours of continuous usage compared to about 7 hours on Hermes. You're not the only one to be affected...... I've posted my cries for help :

I'm still monitoring to see if there's improvement after a few charge cycle.
Darkpal,
Thanks for the quick reply, I have to agree with you on the display thing. What I wanted was actually, just a confirmation from other users that they are having the same battery statics. This will then confirm that everything is normal with my "precious/fragile SGT".
I will do further testing and monitoring.
To PCdumb,
Cheer-up buddy, still I believe our SGT is one of the best tablet out there. ADB and the Overcome team can only do so much nho.
To Darkpal,
On a final note, will the "app lucher" (am using "go launcher EX") will have and effect on battery usage, any launcher you can suggest.
Thanks again for the help
Launchers if coded correctly shouldnt have that much impact if at all on the battery. I personally am using the stock launcher only because am too busy or lazy to configure ADW launcher EX which I have an recommend

battery % weird
Hi. I have a strange question in relation to the topic. I use a P1000 running Gingerbread (stock no mods). I hope you guys have some solution to share to me.
I had Battery Monitor installed so I can check the battery usage and percentages, and Juice Defender Ultimate to you know, save juice.
1. There are few instances that when the unit still has 10% or below power, I sometimes encounter unit shut down (powers off) while I am browsing. So I turn it on again, the Samsung animation appears, but still turns off. Therefore I am forced to charge it (using mains plug). Is that normal?
2. Coming from a critical low battery (5% or lower), with the unit off, I leave it charging (using mains plug) until the battery goes full green (full). 4 hours or so if I am not mistaken. When I turn it on, Battery Monitor displays only 76% or 81% power.
I find that strange since it is supposed to display 100% right?
3. At 76% or 81% while unit on, I plug it to charge again, but does not increase percent anymore.
4. Upon my gut assessment, the unit still performs normally, the standby time and usage time are still as expected, the battery is working fine.
TO DO:
I am thinking to just clear data and reinstall battery monitor.
I am also thinking to install another battery application to display percentage for comparison.
In any case, is there a way to calibrate the unit when turned on to display 100% when it is really full when charged off?
I am not modding or rooting it, I am just a basic user. Any ideas? Thanks!

Try to reflash or factory reset then monitor the battery without installing the battery monitor.
I use "battery doctor to save battery" from the market. You can try that but try first without a battery monitor app.
did you try to use another usb cable? or perhaps your charger is not the original? loose internal battery connector? there are so many factors that might cause your problem not mentioned.

Thank you for the reply bongski. Without any battery monitor app, the problem is I cannot see percentages. But anyway I will do the factory reset, it is another option but I find that drastic and will be the last choice. Also, the USB cable and the charger is the one that came with the Samsung box so they're original. The loose internal battery connector is a bit far fetched, the battery is not user accessible and also the unit is not dropped and carefully handled.
Hopefully I get accurate readings, I will update here.
The battery percentage is in settings/about device/status/battery level.

ok. well i did the following
1. clear data and reinstall battery monitor.
2. install another battery application to display percentage for comparison.
i tried the battery doctor but provided the same percentage reading.
so i just factory reset the thing, and i am observing now (ie. charge later and see if the issue persist). i've no knowledge on how to reflash the thing.
well ok to clear all my doubts i just factory reset it. then i reinstalled my initial apps (including battery monitor), used it til it died (1% until it off itself). plugged to mains, turned it on, and let it charge while ON (of course screen is off). took 174 minutes (3 hours) when it reached 99% and stayed 99% (looks like it does not touch 100%) 4176mV. after 5 mins of non use, it still remains 99% but at 4012mV. with the 1% missing, i guess i can let that go and dismiss as normal now... although i read related thread
http://forum.xda-developers.com/showthread.php?t=866011
and some resetting technique here
http://forum.xda-developers.com/showthread.php?t=921848
but anyway my simple mind would just like to say, "ok its displaying normalcy now".
now i did not figure what caused the tab to display erratic behavior before this, but once i got it i will update again.
Hi everyone. I have owned this smartphone for 7 months. In the beginning everything was fine. The battery lasts a very short time. I checked different roms, there is no difference, the battery status says it is healthy. Checked by several methods. What could be the cause? SOT is only 3-4 hours and it was much more. Not enough for an average used day. Please help.

You said you checked on different roms so there's a possibility that the battery isn't displaying the correct percentage of the phone. If you experience phone turning off even if not on 0% or having the battery percentage stuck for a long time and then starts draining fast then it means your battery is not calibrated and you need to calibrate it to give the correct reading. As far as I know, no matter how many roms you change, no rom can calibrate battery as it is untouch when roms are being overlayed in the system. If battery calibration doesn't work then try restricting apps and forcing doze on your phone. Last option is to start considering a new battery replacement if you want.

If battery calibration doesn't work then try restricting apps and forcing doze on your phone. Last option is to start considering a new battery replacement if you want.

One thing I found would drain the battery in a matter of hours is anything to do with the proximity sensors. Turning on pocket detection would literally cut my battery life in half. Lift to wake and always on display will also decrease battery life. While 120hz refresh is nice, it also shortens battery life. Dark themes on this phone will extend battery life. Amoled screens display black by not turning on the led pixels where black is supposed to be. Just my two pennies...

Yes especially double tap to wake and aod for me kills the battery super quickly. Im guessing it has to do with the miui firmware not properly turning off the sensors during deep sleep. Even a rom maintainer said that aod seems buggy too. Also another factor that drains battery is heat, and rn10pro is notorious for heating up quickly (literally few pics and went from 31C-38C). Frequent heating can cause permanent damage on battery and it'll surely decrease its capacity and lifespan.
Now it is good. Less 10%, sot is 1h. So I think 8h will be during the day. I noticed that the wake-ups had a continuous line now it is intermittent. I think everything is back to normal. Thank you all

Battery calibration pro 1.4 and wiping battery stats with lspeed
(Wiping battery stats is a myth as far as I know, it doesn't contain any persistent long-term data, it gets updated continuously.)
on a similar note, does anyone know why the "Battery usage-->Manage Battery usage" setting gets resetted to optimized from restricted all the time within a few days on A12? I'm witnessed this behaviour on all the A12 roms for sweet(currently on PixelOS) and have never found an answer nor a solution. Has it got anything to do with the automatic permission disable feature since A11? Anyone noticed this? Its frustrating to set that to restricted manually for every app every few days. Thanks!

But it helped with my problem, so it works. 50% battery and already 6h sot. There is a clear improvement

But for sure not in case of deleting battery stats
Btw which ROM you're using?

Xiaomi.eu 13.0.8 Now checking nusantara. A long time ago I read that flashing a new rom should end up wiping stats
