Display + Battery level

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

[Q] Battery drain when idle....

just notice battery drain is getting worse when i tested after i charge my i9000 and left it overnight... at first, it only consume 1% after 5 hours of idle (while i was sleeping).... recently i notice it drained about 5%... an increment of 4% without any usage... does anyone here have the same problem? could it be hardware problem or should i flash a newer version of firmware to test it out? i've turned bluetooth, wifi, gps, 3g/edge off... meaning that i should have nothing running in the background... not even backup...

Under battery history (easily accessible thru SGS tools or Spare Parts), is Gallery reported as using the sensor while your phone is on standby?

My battery drains about 1% every 10 hours of standby. I had to do some tweaks however - flashed back from JPO to JM9. I'm running OCLF lag fix and 'advanced task killer' to get rid of unwanted processes. maybe this could help...

What would you do when ...

hi all ,
my phone is having some battery drain issues ...when i use GXP v22 the battery drain 1% everty minute in standby ..no battery in just 2 hours with GDX it last only 10hours
even when i full wiped , clear dalvik , wipe battery stats the battery still dies to quickly ...
so what would you do?
oh ya i got this rather odd problem the battery went standby for about 4hours ..the battery was 75% and still is ..but then when you use like 1 minute it drop another 1% ..why?
will the launcher be he culprit? i use launcher 360 ..
i off everthing , 3g ,0% brightness , no haptic , no wifi , no bluetooth use silent etc...

flash the other rom after flashing gdx without full wipe.. hope it works ...

Try another "Rom" i guess it's not the launcher but the rom itself, try XGin 6.2 it has a great batt. life. been using it for over 2 weeks now and i'm pretty happy with the battery life.
wifi always on, calling, texting, media streaming, brightness set @ 70%, surfing and my batt last for about 1day 7hrs..

will it help if i give it some time ? maybe a week or 2 ?

I don´t think so.
But that battery drain IS NOT NORMAL, I normally get beetween 24h and 48h of without charging, sometimes even more, and less when I use Wi-Fi or play 3D games.
There´s a battery calibration app on the market:
You charge you phone, an when it´s at 100% you click a button and then the app wipes your battery stats.
You can also set an alarm that rings when the battery is on 100%.

GingerDX v022 on Stock Kernel, smartass governor (default scaling values of 122->600 MHz)
With WiFi and 3G turned OFF the battery drain is 1% in ~2.5-3 hours (phone idle).
With 3G turned on and WiFi turned off the battery drain (almost full reception) is 1% every 4.5 minutes!!! (~7 hours before the battery dies)
With WiFi turned on and 3G turned off the battery drain is 1% every 15-20 minutes (phone just sitting there causing the usual traffic of Gmail, Talk, Sync).
Try to set your phone to a comparable configuration (no idea if GXP has a CPU Governor setting - in GDX it's in CyanogenMod Settings) and try to replicate the test ...
From the "with GDX it last only 10hours" you wrote it sounds like your phone is constantly connected to WiFi or 3G (and maybe having download/upload traffic going on - therefore increasing the power consumption).
EDIT:
Also note that overclocking (as I recall I spotted a overclock thread of yours) will chew the juice out of your battery at a way faster pace.
Keep in mind that the values may differ depending on the GSM/3G reception ... the weaker the signal, the more power the phone needs to apply to communicate with the tower. If you're in an area where the reception is poor you shouldn't wonder about the battery getting eaten.
As a last resort, keep an eye on what applications you have running in the background. The more crap you got running, the more bat drain you're going to have when processes are fighting over CPU time.

NONO i never on wifi / 3G / bluetooth / GPS ..cause of the poor battery i tried my best to save as much battery as possible ...but in no use =( i cosntantly use task killers and i use smartass governer i think i will try stormvix ..oh! and starting my phone eats about 20% each time i does it ..is this normal?

i tried the battery calibration app ..doesn't do jack =(

should i pcc my phone? and redo everything

"starting my phone" translates into what ... ?
Turning it on (from being powered off) and letting it boot up results in 20% loss of battery charge?
That's NOT normal at all ... your charge should lose 1% at best if it was already close to going down by a percent.
Using the phone for a phone call makes it lose 20% battery charge?
Well, that entirely depends on the length of the call and the reception. Going down 20% would be about... hmmm... 1.5h talking time (estimated from the top of my head)?
At any rate ... a rapid loss of charge like your 10 hours while the phone just idles around twiddling thumbs and not being connected to WiFi or 2/3G is not normal no matter how you look at it. EDIT: Unless you overclock sky-high and running the performance governor which would keep the CPU fully clocked no matter what's currently going on.

starting in the sense like restarting eg entering cwm / xrec ...i flashed back to stock now ...gonna do it all again .. i knew this was too much drain i off everything even background data and i use smaratss 122 - 710 , even my brightness is 9% ...

Just for testing purposes to see if the bat drain stays within a sane stretch I recommend you stay with 122-600MHz.
It would also help to install some app/widget that monitors the current clock of the CPU - just to see if there's something which keeps your CPU busy and therefore running at full throttle. I recently saw something like that, I just fail to remember where and what the name of the app was ...........

okay so i flashed to stock last night ..i on everything sync , wifi , bluetooth , data etc for 5 hours it drained only 10% surpisingly ...after 10seconds it restarted and dropped to 3% ..odd...and i fully charged my phone to 100% and left it there for about 1hour and it dropped from 100% - 86% ..any solution?

There are only two things left that I would consider ...
a) The circuitry monitoring the battery charge is bogus and pulling random values out of thin air (would indicate a hardware defect in the loading circuit on the motherboard).
b) Any change the guys who repaired your phone from the hard brick returned your device with a old, almost dead, battery instead of the shiny new one you had in your W8 that bricked (you know, shady retailers thinking to make a few extra bucks by selling off the battery of your dead phone as used-part replacement to earn a "little something extra")? This would closer match to the 10->3% / 100->86% jump symptoms - the battery being about dead and therefore unable to hold the charge and draining like wild.
I don't know which of these two options to favor, but I would give "b" a 51% chance over "a".
EDIT: Stay with the Stock ROM and complain with either the repair shop or SE as the drain problem can be reproduced any given time. This should actually be covered through warranty as the original phone wasn't that old, and the repair is somewhat unrelated. The battery should at least last for two years before you should observe major degrades.

Battery Drains during Standby Mode

Does anybody experience a 3% to 5% battery drain just a few minutes after charging the battery to 100%? It has already reached 100% so I already unplugged it from the charger, but then I noticed after a few minutes, it went down to 97% already, and then in 10 minutes, it's already down to 96%. In 3 hours, it's down to 84%; in 7 hours, it's down to 38% and that's just on standby mode with Wifi/Bluetooth OFF, 3G OFF, GSM only. I've been experiencing this problem for the past few days now. I've already conditioned my battery, charging it to a full charge (100%) after draining the battery until it shuts the phone off. I only charge the battery while the phone is off and usually it takes about 3 to 4 hours maximum to charge it to 100%.
The longest time it reached was 12 hours (battery unplugged from charger) and that is with light use, such as Wifi is only on for a couple of hours, so basically just 2 hours web browsing and skype, 10-20 text messages and 30 minutes to 1 hour browsing the photo gallery or watching videos. No phone calls and 3G is off. The rest of the day, the phone is just on standby mode. I only have at most 10 widgets on the home screen. I have Avast Antivirus running in the background.
I am currently using Easy Battery Saver, Easy Task Killer, GO Task Manager and Battery Monitor Widget. I've uninstalled Juice Defender since I don't think it helps that much when it comes to the battery drain. Currently, the power saving option (available on Note) is enabled at 50%.
Wifi and Bluetooth: OFF when not used

Any feedback or comment on this matter would be really much appreciated. Thanks!

From a personal standpoint. Your screenshots shows that your phone had never ever done a deep sleep at all. the 'Awake' mode is continously consistent as well. I guess the probable reason for that is you've installed ''Avast AV" on your phone. It's always running in the background (whenever the phone is ON). From my experiences, Any background application running would always cause wakelocks and the phone would never enter into deep sleep at all.
How bout you try uninstalling some of the background apps your using esp. Avast AV and give it a day to observe if your still having that battery drain issue. (Don't forget after uninstalling or removing those apps, try to wipe dalvik cache and battery stat and restart your phone after.)
and Oh by the way, I am using Juice Defender and contrary to your saying it doesn't help.. IT DOES HELP save battery as I my Note is able to reach 1.5- 2 days of normal use.
Cheers!

Yeah and download betterbatterystats and do some searching on it. With it you can discover what is causing those wakelocks. Search the web for more info on your wakelocks.

I'm using avast and never seen a drain like that. Only time I have is because of background processing. First thing I would do is turn off Background Data
Then as others have said - check batterystats to see where wakelocks are
Plus a rooted phone is a good thing. Titanium backup allowed me to freeze wi-fi sharing which also made a big difference
Finally - clear all caches from Applications menu and reboot

Only picture that shows that is the one with 1 minute 56 sec discharging time, so it was taken shortly after taking charger out. No suprise of it being almost 100% screen on time there if its only 2 minutes

Also installing "cpu spy" will give the cumulative time that your cpu spent at each frequency including deep sleep , mine is showing 88%
John.

Anti virus app is battery hog, I had avast before too, and I uninstalled it after 2 days using. Also that Juice defender, from my test before, it use up more battery than it saved. turning on and off those 3G/Wifi thing is using up alot of battery. and you know what? even the betterbatterystats use up alot, at least to me, becoz it scan what is up frequently.

Hello! Thank you all so much for your response. I've installed both BetterBatteryStats and CPU Spy and here are the results (please see attachments). Upon checking CPU Spy, it shows there that phone did went to deep sleep, maybe? I'm not quite sure, but it shows on the screenshot that it went to deep sleep for 19%. So does that mean the phone really went to sleep?? I'm sorry to ask this question, since I've never really encountered this problem before with my previous Samsung Wave phone, how will you know that your phone went straight to deep sleep mode?
Also, after 46 minutes or so, the battery went down to 96% already after charging it. The battery drain was already 4% in less than an hour.
@letters_to_cleo: I have not uninstalled Avast yet, since I'm still hesitant to use my phone without an AV. But I will try your suggestion for 1 day and see if there's any battery improvement.
I'm looking forward to your response or suggestions. Thanks again!

i am having problem too with new battery original samsung ( made in japan, finished in korea) previously i use samsung battery made in china, finished in korea. charged it over night with power off. it only last 13hrs. my wife phone can last 30hrs.
i've used batterymix to check the battery usage graph, the usage graph drop very fast compare to my wife phone. i'll post some screen capture of the graphs.
another issue is i used once wifi sharing. after turning switching the wifi sharing off, the wifi sharing service always at the background even after many reboot. how to turn that off??

You might need a new battery. Any rechargeable battery has a finite charging cycle. Just a suggestion.

Hi, all! I just noticed that the battery drains still even during deep sleep mode. After 3 hours or so (during sleep mode according to CPU Spy), the battery went down to 92%. It drains even faster when the phone is in use, especially when Wifi and Bluetooth are on, maybe 2-5% drain in 1 hour.
Maybe there's something wrong with the battery?? It's still a new battery and I can see some improvement each day though, but that's because I use it less each day. Before the battery can only last for 8-10 hours, then it increased to 12 hours, and then to 16-17 hours. BetterBatteryStats' current estimate to empty is 24 hours as of today, but that's because I only used the phone today for only a couple of hours, with 20 minutes Wifi and Bluetooth ON and most of the time, it's on deep sleep mode according to CPU Spy.
What do I do with the results from the Partial Wakelocks? Do I have to disable those apps?? The Kernel Wakelocks didn't show any reference apps running. The screenshots for the Partial and Kernel Wakelocks that were taken a few hours earlier still show the same results after 3 hours.

That would be really bad luck. I got my Note via preorder in Germany at the first day it was sold and since then I charged it everyday, sometimes even twice and there is no difference to the first day. If I get told by Samsung after 6month of normal usage the battery is dead that would be the last Samsung device I bought and I use a lot of Samsung stuff.
@ebichan24
Your last screenshots show between 9:35 and 13:35 5% of battery drain. That's not really a good value but ways lower than before. Did you delete some Apps or what did you change?
And since when occurred this issue? Did you install new Apps before this happened?
On my Note I had this issue sometimes without any changes but it was gone after a reboot.

Agreed with Kanalcommander.... try a reboot in the first instance.
Others have also noted that it takes a few refresh cycles before the phone more accurately reports battery use. Perhaps what you are reporting is because the phone and battery are new (new ROM or Kernel loaded?)
What I have done in the past is to reboot into CWM recovery then clear the battery stats (in the Advanced menu option) Recharge the battery to 100% until it says to remove charger and then use normally until battery down to around 20%, then recharge the battery to 100% again. Do this over a few days and that may help.

thanks, it is new battery two days old.

I was having similar problems with my new note and finishing full charge in 12 hrs but fixed some things and my last charge gave me 2d6hr seriously..few things i did were stop using live wallpapers! Get badass battery to thoroughly monitor stats and then use zdbox to extend life even much eg. I put phone to auto flymode using that app when its sleeping time rest i am more than satisfied even if on GB LC1 fw..waiting for official premium suite for ics since i recently upgraded from sgs2 using ics i miss that smoothness and much better bat life.. Let me know if can be helpful.. Good luck

@TempusFudgeIt
That's what I'm currently doing right now, well, actually, what I do is I discharge the battery until it reaches 0% and turns the phone off. And then I charge the phone for 3 hours while it's switched off, I turn it back on again to check if the battery is fully charged and then I unplug it from the charger.
@Kanalcommander
**Did you delete some Apps or what did you change?
I haven't deleted any apps yet since I don't know which app/s to delete. Most of the apps I downloaded in Note were the same apps that I used in my iPhone4 and Samsung phone before.
**And since when occurred this issue?
This issue occurred since the first day I bought the phone, which was a couple of weeks ago. How long does it take to condition a new battery and new phone?? I'm sorry if I have to ask this question, it's just because I never really experienced this problem with my previous smartphones.
**Did you install new Apps before this happened? On my Note I had this issue sometimes without any changes but it was gone after a reboot.
I only installed recently CPU Spy and BetterBatteryStats and that's it. The drain of 5% from 9:35 to 13:35, the phone's just on deep sleep mode. And then from 13:35 to 23:44, it went from 92% to 74% while the phone is on deep sleep mode at 90% according to CPU Spy. That's 18% battery drain. It's just an unacceptable number for me. I tried rebooting the phone already, but every time I do so, just a few minutes after I turned the phone ON, there's already a 1% drain in the battery.
Also, does the battery really drain faster when the Wifi is ON? I've read in other threads that there might be some problem with the recent OS update that Samsung needs to address. Is this true?? Because as you can see on the screenshot below, the battery was still at 74% by 23:44 and then after I turned ON the Wifi and used it until 01:26, the battery went down to 54%. That's already a 20% battery drain in just less than 2 hours. I was only browsing through the Android Store and Skype.

Calibrate your battery in case you flashed any roms and for first usage I got my battery to 0% 3 times then everything is running great for example its at 47% now its 22 now and I have had it off charge since 7 morning..... i have wifi gps and 3g always on and use music player bluetooth and made some calls

My battery (also only a week old) drains quickly too. Can anyone tell me if widgets draw a lot of current? And then is it only the ones on the visible screen or do all widgets draw juice all the time?

I will ask such thing, did you guys check the battery expiration day ? Mostly sibce you got your phone almost a yeae after it was announced you nay get a bad battery, as for widgets the ones that are always active and asking for informatiom. Like location or weather over the internet yes they do eat your battery kinda fast.

Recurring battery drain? - Caused by memory of using app to drain battery?
Hello!
I used a battery drain app when charge left was 30% to accelerate drain to "die out" stage. After I completed the calibration process for unrooted phone as suggested in various sites (charge fully, switch off and charge etc.) I started using it from a 100% stage.
This afternoon when the battery showed 30% I saw in BMW the current flow was in -10ma to -15ma and it started spiking to hundreds. There was no change in settings or usage. From the 30% level it dropped to 10% in an hour and I had to charge again.
Was puzzled why the battery which was dropping around 0.5%/hour in standby earlier to the 30% level suddenly went down hill. My first guess was it was possible some file in the system remembered the previous usage history and replayed it out.
Any suggestions? Anyone faced this before? Everyone says LiOn batteries dont have memory so if anything it has to be the phone.
Thanks!

3% per hour battery drain while idle

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 ?
