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
The last couple of days I've got a weird problem. When my battery is fully charged everything seems okay and it drains in normal speed (compared to stock).
But when my phone runs out off battery and i start to charge in the beginning everything seems fine.
But suddenly it can go from 75 to 100% in 1 minute.When i look at the stats in MIUI ROM it seems like it's not at same height as it was the last day of 100%. Maybe only 80%.
Sorry for my bad English, but i hope it makes sense.
I've wiped battery stats in CWM. But is it possible that the phone actually is only 80% charged, even though the indicator shows 100% after wipe?
Because if the ROM think the battery is charged and wipe stats it will afterwards only charge to that point and the battery maximum will decrease over days?
If that's possible, how do i full charge the battery? Just leave it in the charger or?
I hope you can understand what I mean.
Thanks in advance
Hello
Does your phone charge to fx 75% and after that doesnt get higher until after you restart the phone?

Yes excactly. But the numbers differs.
Today it charged to 100% though.
Got the same problem?
Sent from my Optimus 2X using XDA App
have you try calibrate your batt again
yes my friend have this problem too, maybe there is software bug
After flashing Celebration HD 2.0.1b I first used Battery Calibration from market to wipe battery stats. Afterwards the battery indicator problems started.
Yesterday i decided to wipe battery stats manually in CWM and drain to phone to 2% before charging, and afterwards I was able to fully charge the phone.
So maybe the bug in is Battery Calibration app?
I decided to install Juice Plotter to monitor the battery and compare it to one build in in MIUI. Just to get some more data.
Hello again
Yes i had the same problem as you, with my previosly 2 lg optimus 2x, and returned them because of the problem you mentioned. I am on the third op2x and luckily this work good
So if i were in your position i would try to go to the dealer and shift the phone with another lg optimus 2x.
Best regards

The user said that he started to have problem after a new rom and wiping battery stats, changing phone for that is not the smartest move at all. Is like changing phone because your rom doesn't work.
I have a similar problem, after you wipe battery stats you don't have a reliable indicator, for me the phone took 3 hours to get from 99 to 100%.
I also noticed that my miui ( 1.8.5 same for 1.7.29) doesn't update battery stats when the screen is off so all those plotter don't work, and i think this messes up with the battery indicator (I guess the phone doesn't have enough data to make a decent estimate)
I think is miui + wipe battery stats that can be problematic
I know that but i am just saying that i also had the same problem with the stock rom.
Best regards

How old is the battery? How many cycles does it have?
I know from laptop Li-Ion batteries that the voltage vs. capacity is not linear.
When discharging, the voltage will steadily drop to a "wear-level" where it will jump to an almost depleted level. When charging, this "wear-level" will be at the top.
Why I am telling this? Because if this mapping is kept in SW and you wiped it, Android needs to relearn it again. So at 1st complete charging/discharging you would see a % sudden drop/raise, but at the next cycles it would be linear with time (although the total time will be smaller than a new battery).
When laptop/phone battery tips talk about calibration, it is so whoever monitors the voltage (circuit in battery or SW) to know were the wear drop will be, so your estimates to be better.
As an example, I had a very old Thinkpad that did not have any calibration, and it would discharge to about 40% and drop to 5% within seconds. But when charging, it would raise steadily to 70% (from that 5%) but 70% to 95% in seconds. After years of use, that percentage gap would just increase (40-5 got 60-5, 70-5 on discharging).
PS: my current Thinkpad has 4 years and the battery capacity is 49% with 150 cycles. But this one has a nice feature where if the battery was above a certain percentage, plugging AC would not charge it (and thus save a few cycles). I used it set at 70%.
PS: LiIon batteries have cycle count, heat and time as main enemies. Also don't like prolonged (think storage) low charge.

I have when i turn off my fhone and i charge it it shows a battery icon whit an error in it ics lgp990 please help i dont no what tho do
hello
i just wanna ask something about my battery life on my x8...here's how it goes first i fully charge my battery up to 100% until it says on status battery full...then i unplugged it..after it i texted for a few minutes...and i check the status of my battery and it says: 28 mins 23s on battery..my battery is on 96%..is this normal.? or somethings draining my battery,?
i use minicm7 2.2
this is normal since battery is heating itself while charging, and when it cools down it shows less percentage of itself... to maximaze your current battery life, calibrate the battery:
1. charge it to 100% no more no less
2. leave the charger PLUGGED IN, and reboot to CWM
3. there you should find somewhere under options or advanced "wipe battery stats", and you press that
4. reboot your device and when it starts up it will show about 91%, charge it to 100% and you have your battery calibrated
NOTE: the charger is always plugged in
ok thanks i'll try it... one question should i drain the battery before calibrating it.?..as in zero percent??

Yes , that is recommended.
Also , one advice from me.
Even after calibration , whenever your phone says 100% charged , reboot it while the charger is plugged. You will get the exact battery charge after reboot.
Do it every time your recharge your phone.
Then stop rebooting when you get a 99% or 100% after a fresh reboot. Trust me , it helps.
ok thanks for the advice i'll try that too...
it is normal dude ....mine is giving 1day on heavy use
use zepplinrox's supercharge script...it really made a CONSIDERABLE change to m battery usage time
I have one question: "Why my battery is giving 6-8h. My battery 2 days ago giving 24 and more hour." Sorry for my English, but i am from Poland
what happened 2 days ago? did you install new ROM?
The OP might not have needed to install a new ROM, just an APP or maybe just a combination of APPs running. My phone sometimes canes the battery in a couple of hours from 50% to nothing for no apparent reason. On both stock and custom (actually better battery life on custom) it lasts about a day but sometimes about 6 hours! Not sure what is going on as this happened on both the stock 1.6, 2.1 and the custom 2.3.4!
Hi guys,
Since last week my Ace battery react very weird, it drains from 100 to 10 in just few hours. Currently im on Meizu ROM. (Previous ROMs: Democracy, MiUi, Nightly)
I have applied many tweaks to save battery life but all went in vain.
Guys please suggest me for this situation.
Thanks,
Swapnil
Change ROM and try..If its still not working, get a new battery
Controversies,controversies everywhere :what:
Already changed the ROM from democracy to Meizu, but problem still persist.
Is there any tweak to save my battery apart from the new battery option?
Thanks,
Swapnil
check if something prevents your device from entering deep sleep. (background processes)
then charge your battery, wait till its full (till you get notification in setting, that is isnt charging anymore)
=>
use the hell out of you battery, till completly depleted and phone shuts down.
=>
recharge battery, wait till you get notification that its full => keep charging for some hours. (best way to do this is to charge overnight.)
might work...or not. just try it.
Check whether the battery is swollen or not
If swollen replace it immidiately
This only could be the problem
Encoded by Me, Decoded by xda
Is this a new ROM that you just switched to? I had faced a similar issue when I switched to one of the ROMs. Thankfully it wasn't a batter issue. Let your battery reach 100%, go to CWM recovery, in advanced select wipe battery statistics, do not charge the battery till the battery goes to 0 and the phone dies. Check after that. You can check your battery health by dialling *#*#4636#*#* and going into battery information
Hi,
Thanks all of you for your reply, the problem is somewhat resolved.
I have wiped out battery status, installed the batterybinstat apk and its worked for me. Now my battery last for 1 day with wifi on.
Thanks,
Swapnil
Hey guys, its my first post on this forum (or on any forum for that matter) so I apologize if this is in the wrong section . But recently I've been having a problem with my S3 mini and hoped I could get some help on here. So a few days ago I got a 4000mAh - 3.7V extended battery for my phone because my old one had broken. The old battery was the stock battery that came with the phone. Before I bought the new battery I also installed the PacmanROM on my android. But since I got the battery the percentage my android displays has been completely wrong. I'm pretty sure that the battery is fully charged after over 16 hours of charging but the percentage the phone displays is only around 65% and no matter how long I charge it the percentage never reaches 100 and it will stay on a certain value that will randomly fluctuate if I restart the device. So is there anyway to make my phone display the correct percentage? Thanks for your help!
In my opinion, extended batteries are more trouble than they're worth. I have dabbled with them but all have failed at some point (even brand new). If you put the battery on a flat surface and it 'wobbles' at all then its duff. I use stock batteries. Sorry if this is not what you want as an answer but just my experience with extended batteries.
Sent from my GT-I8190N running CandyKat
Thanks for the input anyway! I've never tried any other extended batteries so I ignorantly decided to get one hoping it would work well. But anyways I believe that its not the battery that's at fault since the battery seems fine to me (no bumps showing a faulty battery). I have a feeling that its my old battery that's at fault or the system still possibly assuming its a stock battery. Well I'm no expert .
Awfully I can post the link for fix this..
The APP for fix this 'bug' is "Battery Calibration", it delets a battery file, and after restart the cellphone, that file is remade with correct data.
Well I looked into Battery Calibration and have managed to find a fix! I charged my phone to "full" (which my phone only displayed as ~50% at the time) and once the battery percentage stopped increasing I left the phone to charge for a few hours after that. Then when I was sure that the battery is actually full, I installed a battery calibration app and "calibrated" my battery which deleted the batterystats.bin file. I then waited for my phone to completely run out of charge, which I sped up with an app called "battery discharge", then when I let the phone switch off by itself from an empty battery. Once the phone restarted the battery percentage displayed was correct.
Try Battery calibration
isnt battery callibration a complete myth and placebo? deleting batterystats.bin shouldnt help as it just contains data about what consumed battery juice
