[Q] Battery life: Normal or draining too fast...?, + few more questions..

Hi!
So I'm using GSM Galaxy Nexus (YAKJUXW) 4.0.2 I9250XWKL2 with stock original baseband radio and others.. (nothing changed..)
My Nexus have bad battery draining problem in ICS YAKJU 4.0.4 so I do not update my Nexus to YAKJU!
I feel like my Nexus uses too much battery, it loses power too quickly..
In idle my phone drains little bit too fast and when I listen music or when I just going to internet few minutes then always battery drains too fast,
I have tested many other basebands, kernels and ROMs and the battery draining problem has been on my Neuxs a long time now...
Also sorry for my bad English! I Hope you understand what I wrote..
here is screenshots:

My Galaxy Nexus has been the most time in idle, bluetooth was on only something 4 minutes or more...
WiFi: I do not turn it off!
3G: I'm not using it!
Brightness: something 70%?
My nexus has been in phone service once, they flashed ROM again and changed battery!
sometimes in Google Maps it can't find my location if I'm not using 3G, is it normal..?
today it worked fine!
in Music player some songs cannot be played when i lock screen so then I have to convert them with other applications to badder quality then them works.. is it normal? how to fix? without DSP manager...?

You have some wakelocks over there.
And your WiFi radio don't just run on Oxygen right.

Well you said you were listening to music? That's one right there. If you were listening to music I think 80% is good after 15 hours

yeah but music listening 30-45 minutes does not use so much battery when screen is off..
it loses something 9% when listening music from google music player something 30 minutes..

Bars doesn't tell me anything, download BetterBatteryStats, google it, should be free on a thread in xda.
You need root for BetterBatteryStats to work. then post a screenshot of your partial wakelock tab.

Battery life
You can turn off mobile data when connected to wifi. I use automateit pro to turn off mobile data when I have a wifi connection - mobile drains much more battery than wifi.

And yes, turn off Sync, apps that kept syncing will drain battery.
And if possible, turn off mobile data when not using it.

all what I don't use them are disabled.
but I never turn off WiFi..
I don't have much apps which could use syncing...
I've download app that disbales notifications in the notification bar and it is not using battery..
I have to go phone service when I have time and then I can maybe get to know about that what drains battery...
it can't be any app, I've force closed apps which uses 2%or more battery when I don't even use them..

Most likely, it's an app misbehaving.

Try using something like juicedefender lite or go power manager from the play store. They can help you set up different modes that toggle things that eat battery life. They also tell you what apps/hardware is using the most battery.
I found that on mine, the screen was using a ton as was the 4g at work (bad connection). So Juice defender will turn off/on my 4g every 15 minutes and download updates without draining my whole battery. Good luck!

The thing is I use the task manager a lot closing my apps and all. But it has not improved my battery life at all. And its frustrating since I'm out of the house almost the whole day (9 to 10 hrs sometimes 12 hrs). Should I change my kernel or something?

stop using a task manager. that is probably what is killing your battery.

Add this tweak to /system/build.prop
ro.ril.disable.power.collapse=0 - This setting puts your phone into a deeper sleep when on standby. This may improve battery life.
pm.sleep_mode=1 - This sets the phone to use power collapse when in standby.
0 - Power Collapse Suspend
1 - Power Collapse
2 - Apps Sleep
3 - Slow Clock and Wait for Interrupt (default)
4 - Wait for Interrupt

there are many reasons that are responsible for fast battery drain.
1. App using the Processor to its fullest.
2. App misbehaving (restarting multiple times in background)
3. Overheating of device due to any external or internal factor
4. Battery fault.
I would recommend you
1. Set the brightness of your phone to "AutoMode"
2. Use Power saving mode while not playing resource hungry games.
3. Download Clean master. that will solve the app misbehaving problem which results in Overheating.
4. Charge your phone wisely.

Android system draining battery

The android system is draining my battery pretty badly. It's taking about 25 percent of my battery. I have my Gsiff_daemon deleted, but it's still taking quite a lot of my battery. My phone would go down 1 percent every 5 mins in sleep mode. Is this normal and how can I decrease the battery usage of android system? I'm on 4.0.4 stock rooted.

When you have battery issues you need to post a battery info screenshot. Showing your battery use and what is using it. It will help Diagnose the issue.
IMO (I am not pro) I would think being on stock you should have no problem although you are rooted so I think. Its either a hardware issue or something you did. How did you root your phone? if you followed a Tutorial what tutorial did you use?
What i would do is first charge the phone to 100% then let it drain to around 5% and post a screenshot of your battery usage, I would also post a History Screenshot too.
After you have done that you can patiently wait as i bet someone more knowledgeable than I will post something about your issue.
Although Since your rooted you could Install a New Kernel that is made for battery life. That should help if your ROM is not the suspect (I think it could be) Next I would also flash a good stock based rom (that is if you like and want stock based). Pimp My Rom also Has some Battery Saving Tweeks in it if you wish to not flash a ROM try PMR to tweak your system.

I didn't really cared about my battery life before since I always have extra carried with me at all times. But my power is out because of hurricane sandy and I have no idea when will the power be back up. Now every percent battery counts since I won't be able to charge. I'll try to put screen shots up but I only have my phone because my laptop battery died already.

Go into your battery screen and tap on Android System and then scroll down. it will show you all the processes that are associated with that particular facet of the ROM/Battery. In there, you can see what is being used by Android System and hopefully something will spark your eye. Do you have an Alarm/Clock setting, Calendar, media scanning,...? You can force close the offender.
Also you can go into Developer Options and tick Show CPU and it will show an overlay on your homescreen that will show real-time CPU usage.

I turned on cpu usage in the devekoper options and I see that x.xx/x.xx/x.xx (x are numbers I can't track them down because they're constantly changing) are always on the top and takes up quite a lot of cpu. Is that something I need to worry about?
Sent from my SGH-T999 using Tapatalk 2

I would reboot and once it is back up and running, go to Settings>Apps>Running and FC everything that you are not using. Then switched to Cached and FC everything that populated over from running and anything else that you don't need.
When I say need, I understand that you are in the danger zone and w/o power. You don't need Facebook, MediaHub, Music/Video,...Not that those are specific to you, but if you only have one battery left with no power in the future, then I suggest going bare bones for the time beaing.
***************
Sidenote: I was just reading about some things and see that some people in NYC are using Hotels/Gas Stations/ Stores that still have power to charge up the cell phones. Not sure where you are but might be worth looking into. How many times have you gone into that corner store? Do they recognize you? Maybe they could share some power. See where I am going with this?
Be safe

I had "Android System" eating my battery too. I'm stock/rooted. I had Cerberus installed briefly, uninstalled - about when my phone started being hot (bottom third) when sleeping in my pocket. Drove me nuts - sorry, but I simply cant tolerate an IDLE phone getting hot in my pocket! Anyway, I rebooted the phone, turned it off, pulled the battery, installed Better Battery Stats - eventually the phone stopped having massive drainage from "Android System" and now it's not hot anymore whether it's on browsing the web or idle.
I guess there are two points to my post 1) the way I could tell my problem was fixed was the phone stopped getting hot -and- 2) the problem hasn't come back for me after a simple fix of multiple-power cycles. I've seen mixed results with a fair number of people saying that rebooting their phone fixed there problem and about an equal number saying the problem either wasn't fixed by rebooting or it came back again later.
If it happened to me again I would open a Terminal and run the "top" command and just keep watching it until I figured out what was eating up my battery (CPU time).
EDIT: Oh - and to confuse things more I used Titanium Backup (pro) to freeze/un-install some of the T-mobile bloatware in addition to setting email to sync slightly less often...

I have my power back on and factory reset my phone. I see android system had already taken 30% of my battery after about an hour of use. There is close to nothing on my phone since it just got factory reset. I don't even know what to do anymore, I really don't want this "android system" sucking so much of my battery.

Id suggest flashing the full stock fw via Odin. Possibly something got corrupted during an update maybe.
I saw uou used Show cpu usage earlier. Don't worry bout the numbers, but watch for the processes that seem to stay at the top and let us know which they are.
You can get the fw from my thread here.

The cpu usage is very high I think it constantly stays at 1.2+ 2+ 4+. It can go as high as 9. I'll try flashing stock rom again and see how that goes later today.

Ok, but beneath those numbers you should see the list of processes. Theyll be constantly changing but you should be able to pick out which ones seem to stay at the top.

The only thing below the cpu usage is the system_server. Android system is only hogging 11% of my battery today. I don't know why was it at 30% yesterday but it seems normal now.

[APP] 'Data Lock' : unplug 3G while the screen is off

Hi
I'm not a developper but I created an app with the Tasker App Factory that unplug 3G one minute after you lock your screen. The one minute delay is here to prevent the phone plugging and unplugging at any time the screen goes off. During this delay, if you wake your device, the process will stop and begin again when you turn the screen off. When the screen is off, after the 1 minute delay, 3G is stopped while the phone is in your pocket to prevent battery drain
Once it is stopped, if you wake the device a new 5 second delay is started, for those who just want to check the clock , and then the 3G is plugged with a ''Data restarted'' toast
Note : Tasker IS NOT required to use this apk :victory:
Feel free to request any modification like the delay or the toast text, I'm here to share such things. And if it helped, don't forget the :good: button

cpu usage
Your app gave me a watchdog alert as it's using more than 50% CPU. This would counteract any benefits as eating CPU results in battery drain.
It also uses 15.3 mb of ram when its role is simple and in no way justifies the ram/CPU usage.

Going to try this as I am tired of manually switching to 2g all the time.

You seem to be right... That's too bad because I use tasker 24 hours a day with many profiles and tasks and it saves my battery!

2. create widget or icon in notification to enable or disable
3. put in google play for updates

Well the answers simple. Uninstall Battery Guru.
In my experience it doesn't really do anything.

I had the same issue and once I uninstalled Battery Guru it was fine.

I'm just reporting what I see. It's up to you to decide what you actually end up doing.

You have Beautiful Widgets too, maybe you could use that instead for weather. There are a lot of skins for the widget. Also Lux seems to be waking up your phone a lot, perhaps you could get rid of that too.

But Lux is a battery saver isn't it? It periodically adjusts the brightness levels (it's not like auto-brightness)

Turn auto brightness off and set you screen brightness to the lowest possible you can tolerate. Any app that is running is a battery consuming app. Also BBS should be frozen if your not using it to diagnose an issue the least you have running the better off you are.

I had really bad battery performance when I was using Lux. It does seem to adjust brightness levels in an adequate way, but if I recall correctly, I was getting a lot of wakelocks when I had it. So while it probably was saving battery due to better screen usage, it was killing me in the deep sleep department.
Just my experience with it.

I will do that then for sure.

I could suggest Greenify for your installed apps (not system apps). But with the alarms it looks like you set alarms in your stock clock and on your 3rd party clock which is what could cause some wake locks

So I keep getting these wake locks when my phone should be in deep sleep. Caused my phone to drop 25% over night with no activity. I've done research on it but most of it says that this app is for your apps that sync. I've checked my syncs and everything seems Ok. Is there anyone that can shed a little more light on the subject?
