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

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.
Hi guys,
after flashing the starburst rom and over clocking and several tries to calibrate the battery my battery is still draining a mile a minute. I used the battery calibration app....have let the battery fully drain and charge at least 5 times now and I still can't get back my battery life!
I'm thinking the root of the problem, well...when I go to settings than battery use it says the screen is using between 70-80% of the battery...I am assuming that what is sucking the life out of my battery but I have no idea how to fix it. my screen time out is at 30 seconds...brightness is almost as low as it can get. ITS DRIVING ME NUTS
I am assuming I calibrated the battery correctly cause it does not drain at all when the screen is locked.
please, any help or suggestions would be greatly appreciated, I am ready to rip my hair out!
I just opened battery calibration app its at 70% 4mv isn't it supposed to be like 4000mv? or is just abbreviated?
I just flashed a new rom and still having the same issue!
trying to calibrate the new rom using battery calibration and its barely charging...been stuck on 61% 4mv for about a half hour now..
is it possible that this problem is being caused because I installed the roms with ROM manager and not CWM?
I apologize for what questions may seem dumb...I am a noob....but i have searched relentlessly for answers on this specific problem here with out finding much yet.
disregard that last question..lol..u can see how badly this has my brain turned upside down
So my X1 running Code Butter NAND ROM is experiencing a 3% battery drain per hour. It's not really that much of a big deal since I can make it last a day on idle state, but what's the use of that? I even bought a new battery. I did all the drain the battery first procedure and charge it fully thing already. Last night, I charged it. At 6:00 AM, I unplugged it. When I came back home, the battery readings were at 60%. It was at 100% when I unplugged it. Please help me with this problem.
Before giving any tips, here's what I have already done since I did some research on the forum...
I have reflashed my device. I have been flashing different kinds of ROMs but still experiencing the same battery drain.
I don't have any apps which may be the cause of this. If there is an app, it must be Swapper 2. It's kind of famous already.
I always calibrate my phone after flashing. I just flashed it 2 days ago. Calibrating actually fixed the battery indicator.
I have used CPU Spy. According to the readings, my phone enters deep sleep.
I don't use any task killers. I do have a rebooter app which can hot boot the device. However, I don't use it very much because of the speed Swapper is giving.
I have cell radio turned on. That's it. I don't have any other connections. I don't have 3g or whatever.
Even though my phone enters deep sleep, I have installed betterbatterystats XDA version. Unfortunately, I didn't find anything interesting.
I don't have any battery saving apps. I used to have JuiceDefender Ultimate. However, it didn't do much. It still drains 3% per hour.
Please help me with this problem. I think I'm starting to annoy people for asking so many questions. This shall be the last thread I'll ever make. I only start new threads if I can't find any solutions. Please help me.
Well, the battery driver in the kernel isn't optimized nor completed, so there is a major general problem with it... Currently CoolrunnerII is "playing" with an X1 to try to map everything, but as Elibl discovered, the battery driver isn't correct and should be replaced with the same as x10... But until then, the battery is draining just like this.
Yes, but there might be a solution.
I'm getting tired of all these android issues. I'll just install Windows Mobile 6.5 with the HARET.exe thing. Thanks for the help anyway. What's the best "HARET" android for your opinion?
Twizdroid or sensedroid
Hi there, if you will be trying again someday a NAND ROM, here is a solution that worked for me: http://forum.xda-developers.com/showthread.php?p=16808932
I have bought a new battery and now on NAND ROM ZeamDroid v.7.2.1 my battery drain is about 1% per hour in sleep mode. Apps that I use: SetCPU and Battery Monitor Widget.
We don't have the same device but we seem to have the same issue.
Did you ever find out how to fix it ?
Hi,
I got my (used) note 1 about a year and a half ago. I've installed alliance rom from the get go and experienced some battery drain. At first I thought maybe it's the battery, so I got a new one. This also didn't help but as the drain wasn't significant (I wasn't even 100% sure it really was a problam), I just continued using the device. After about a year the drain got worse (wasn't a battery issue, as I checked with an almost un-used battery). I figured changing a rom might help, so I moved to CM11, after installing an official version and re-rooting the phone. It made no difference, but I continued using the phone anyway. The battery drain got worse and today it drained 80% in 7 hours with almost no use (talk for about 5 min. and maybe 30 min. screen time with wi-fi on but no GPS). Also, the phone started heating a lot (it got to a point where it was uncomfortable touching the top of the screen due to heat. But it didn't shut down). Then the phone started rebooting itself or just freezing until I had to do a hard reset about once a day. I think it's only when it's in use but can't be sure. another issue is that when I try to take more than 2-3 pictures with flash on, the phone reboots (flash off - no problem). The heating was solved by underclocking the device, but the other issues persist.
I thought about changing ROMs again, but as it didn't help last time, I decided to ask for advice here first.
Any thoughts?
Taking pictures on low battery or bad battery with flash can cause the phone to power off. It could be either.
Install wake lock detector from the app store and check what's draining your battery.. Then either paste a screen shot to get more help.
Thanks, I'll do that.
But just to clarify, the phone shuts down (abruptly) when using flash event if the battery is charged. Also, there's no such issue when using the led as a flashlight.
OK, the drain in the last few days was due to a game I installed and forgot to greenify, so let's put the battery drain aside for the meanwhile.
Question is, what can cause rebooting?
