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

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
After a difficult update with Kies I was able to upgrade to Gingerbread.
Everything seemed to go well the first time then I found drain battery and slowing down on the system.
So I decided to make a simple wipe which reported the phone as fast as at first, but the battery still has problems.
In one night from 90% it was completely drained so today I decided to use 'Battery Calibration' made from user 'marosige'. This time in 5 hours I lost 30% of battery life using some sms, internet for 15 minutes, and playing cut the rope for 10 minutes. More or less.
However I have to see if the battery loses all of a sudden like last night which is the biggest problem.
All of this is not normal have you any advice?
Thanks in advance
Hi Fattox,
Dont worry your socks off I flash Roms quite often and this requires me to calibrate the battery. Sometimes with certain Roms I find the battery may drain quickly the first time and then things get better.
You say you have calibrated so that means the app you used should have deleted the old battery stats from your systems file. In saying that if you follow these next few step you should be ok (unless there are other issues causing the drain)
1. Make your you drain the battery fully until phone dies and can't be turned on by pressing the power button then....
2. Plug in phone and keep it off until battery is fully charged. Don't take it off charge as soon as it says full. Just let it go for about an hour more or so to ensure it's at capacity.
3. Turn phone on and use as normal until dead...
Providing there are no other issues causing the battery drain you should find your battery usage to be satisfactory. Remember to turn off wifi and gps when your not using them as well as maybe turning your screen brightness down. Anything that uses less power the better....
Hope this helps.
between the recalibration with the app and your point 1, I had the same problem: during the night the battery loose all the energy.. so strange.
All this after I upgraded to Gingerbread.
I'm going to test all this week then I'll spend my warranty.
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?

see jvp and jvq are bug fixing firmwares and i didnt use any custom rom ,..,i have stock firmware which i just rooted and didnt use any mod or rom.,,.,.jvp and jvq are stable roms diffrence between the both is that in jvq browser is improved gallery improvement,.,..,etc
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.

I just got my SIM card replaced today. The one I had used before was about 12 years old. So whenever you-re having battery issues, make sure your SIM card is not the cause for it .
I am experiencing an extreme battery drain with ALL the roms i tried.
The battery lasts maximally 5h, with 20-40mins of 3g browsing.
Currently at 38%, display max brightness, 2h 12mins usage,78% in battery use / Opera Mobile usage 22 m
ins, 9% in battery use.
13h since last recharge (i went to sleep).
Also my battery magically charges itself while on standby, up to 4% per hour.
Im pretty sure my battery is calibrated, even if it isnt it would give me the same power.
Also it heats up to 59c (even when i wasnt on 1.2GHz kernel)
I think u need a new batt. Same thing was happening with the iphone and untill i've replaced the bat the same thing happened.
.
Thought so.
Will flash stock 2.3.5 or should i flash 2.3.3, which is the latest official for my network?
I think it doesnt matter...
Well the guys in the service are a$$es so it will take them about 2 weeks for it...
i'm not sure tere is such thing as stock 2.3.5 and i think only MIUI has this. Last is 2.3.4 but i might be wrong.
There is xxjvs that is a 2.3.5 firmware
No your battery isnt wrecked neither magic took place its just that ypur battery stats are messed up!
Fixing them-fully recharge your battery until it shows 100% then switch your phone off and then let it charge for another 1 minute then go to recovery mode( you have cwm recovery right?) Then go to advamced then delete battery stats from their and reboot your phone ! Then for best result ypu can fully drain your battery to nil unt it switches off! Your battery stats should be now fully fixed ! Dont worry for deleting battery stats system will make them again in a few minutes or on a reboot !

Hi I rooted my phone a few weeks ago hoping fir better battery and performance when needed but every since tge battery calibration has been messed up, for example earlier I was using my phone to music through ear phones and looking through Facebook (using 4g) it said I had 73% battery left but then died, phone was charged to 100% over night and only had about 35 mins of actual on screen time.
Ive tried many different battery calibration apps but none work.
Sometimes when the battery completely discharges and turns off and I plug in the charger it wilk give me the actual battery % but when I turn on the phone it will say 40% even though its actually only 12%
Should I use a different rom? Can someone recommend me one for my c6903 please
