Best radio signal to use? (battery life)

I can use *#*#4636#*#* and I read somewhere that it can help with battery life if I set a certain antenna from there? I forgot where I read it though, if someone can please let me know that would be great. There are NO rogue apps running, I only have about 10 installed.
The phone is 4 days old, so it could be why but I've battery cycled it twice already (letting it run dead and recharging it for 10 hours). All my widgets are off except weather and that is set to update every 3 hours and it is NOT using GPS. Wifi is off, so is bluetooth. Gps is off as well.
Is anyone using maximum power saver or just the regular nighttime setting for those reporting better battery life? I also uninstalled launcher pro, it seemed to glitch my phone a lot with the google toolbar and also seemed to have a slightly bigger toll on my battery. Also battery health is stating "Good". Is that the best or does it still need more conditioning?

You probably shouldn't change things in there. Look elsewhere to conserve battery.
You didn't note what your battery life is like either. But you should still let the battery charge and drain a few more times before trying to squeak out more battery life by modifying something like this....

Well I'll give you an example. The phone was unplugged almost 6 hours yesterday, and I used it around 3 hours and 46 minutes max. It got down to 5 percent and shut off. I had my music i was listening to for 25 minutes. I had my IM program on for about an hour, had a 12 minute phone call. Was texting back and forth mainly, and I checked a few things on the browser and exited out. MY IM program uses GPS to get my location but only when I request to do so, then shut the gps off. I force closed it when I was done to be sure it wasn't gonna drain any more of my battery. My notifications are off mainly except for my texts and such. And this was with JuiceDefender on the last half of the battery.

I don't like programs like Juice Defender to be honest. They usually go buggy and drain the battery more than it saves. People just get excited and leave positive reviews.
I'd honestly reset to factory settings in case there was a one-off glitch. Set things up again and use it like you would normally to gauges things. My battery lasted over 40 hours from the first charge.
With results that bad, I wouldn't troubleshoot beyond resetting it. Take it back if that's the case. That's not right. And it's not worth your time.

Thanks. I just got the phone not sure why I would need to factory reset it. Is there a way I can back my data up and such like texts and pics/apps?
Also 40 hours!? Jeeze do you like never use your phone at all? haha. That is insane my iPhone 4 never even got that good of battery life.

That code just pushes your phone to use EDGE only and not 3G. It can increase battery life if your phone is constantly trying to hold on to a spotty 3G signal, which can be common .

Ridiculous battery drain on standby

It seems that the battery drain on my newest N7 (RMA'd first one) is waay worse than on the other, I'll attach some screen shots of what I mean.. it may be just the WiFi is using a lot more than the other's :S I left it 4 hours alone with WiFi and the battery drained 20+ % which even with WiFi on seems excessive does it not? Is it possible I got one with a faulty WiFi radio? I will be testing tomorrow (or maybe tonight) to see battery drain with WiFi turned off to compare, because it also seemed to drain fast when I was just out and about with WiFi off :/ worried I have bad battery, deep sleep isn't working right (it is going into deep sleep or at least thinks it is from looking at cpuspy), or faulty WiFi... or just too early to judge XD has anyone noticed battery improve over time ? I forget if I did was a month ago I got the original
BTW first screen shot was taken pretty much right as I was leaving for work, so you can compare the battery drain there..

I doubt it's a bad wifi radio, its probably an app that is syncing like crazy in the background.

I'm currently watching the MediaServer app use a disproportionate amount of battery (14% and rising). I deleted a number of images which must of kicked in the scanner which must be very inefficient.
I also noticed my N7 become very slow at the same time.
Possibly you downloaded a large amount of images/music/etc before putting your device to sleep...

I really wish I could figure out why maps keeps starting a process.. can you check to see how many instances of maps there are ? In particular one running Prefetcherservice.. as for the other comment, media server is sitting at 6%, android is at 14%, and screen at 67%.. though I did copy a bunch of songs and pictures over after the RMA, is there a way to fix these or should I delete them to see if it gets better ?

Bahaha good one I dunno, the problem is that this is literally my fourth N7 since the other three allll suffered from major screen lifting, so maybe I am looking for something wrong just so i can make sure it's perfect... Though I do think the battery life is pretty weak, I think I may have figured SOMETHING out, the only difference between this and my original is that my original had a huge section of the map of my area downloaded, and since I did that maps hasn't started any additional processes.. so good sign ? maybe ? haha

Yeah this might be a good time to stop looking for trouble and just enjoy the tablet for a while. I drop mine on the charger in the morning and don't ever really think about the battery other than that. Whatever the battery stats say now they won't say in a week and they won't say after you flash to a different ROM. If you have wifi on apps will sync and the tablet will loose it's charge. I'm never far enough away from an outlet to make it much of a concern. So maybe just take a breather, install the Angry Birds and have some fun for a bit. Eventually we'll have ROM's and kernels that make this thing sip electricity but for now I get the few hours a day I need out of it on one charge so I'm set.

You think the battery life will get much better than what it is? My only other android experience is my HTC Desire Z which has a horrible battery as it is so it didn't improve much at all with custom roms
Speaking of improved life through ROMs and kernels, have you noticed any kernel providing particularly better battery life ? I'm on trinity right now, no voltage changing, but underclocked to 1.1 ghz from 1.3

Factory reset, see if the problem continues. That's the only way decide if it's a HW problem.
And my N7 uses effectively 0% battery in standby, it was off the charger yesterday for 6 hours and when I started playing around it was still at 99%. I turn off wifi on screen off, however.

Use http://forum.xda-developers.com/showthread.php?t=1179809 to find out what's waking up your phone, the apk is in the second post. Install, charge it up, unplug, leave for 4 hours idle then look at partial wakelocks and alarms.
I saved quite a bit of standby time by disabling location services and Facebook.

If your not using nfc that could save battery?

So it seems like partial wakelock is mostly audioout_2 which i assume comes from me playing a game with music amongst other things?
Alarms says com.google.android.googlequicksearchbox has 50 wakeups, and maps has 38 :S why does maps keep trying to kill me?! and what is the googlequicksearchbox doing waking the tablet up...

Wlan_Rx_wake seems to be the culprit of semi bad battery. Is there a way to prevent the tablet from waking up all the time? Maybe just unsync or turn off WiFi instead?

When my battery drain was bad I had something like 250+ wakeups from maps under the alarms section in only a few hours off the charger and Maps was showing up as the most common reason for partial wakelocks.
I think AudioOut_2 is normal - Im not sure what it does though. Im now at 8+ hours of standby with 99% battery. Under alarms im showing 138 Maps wakeups and 76 from google quick search box. My drain is all gone now though so i assume this is within normal range. The better battery stats thread and a few other threads on XDA have detailed descriptions of the different battery draining wakelocks and possible remedies. Not all wakelocks are bad though.

n00b here, need help with battery issues

Hi there; this is my first post so please go easy on me.
Bought a Nexus 4 which is my first Android device, but the battery life is bugging the hell out of me. Surely the screen should always be at the top, right? I left it to sleep overnight on a full charge to find that it had shot down to 60% when I woke up at 7 this morning.
I haven't rooted or flashed or anything like that, because as I said, I'm an Android virgin. I have location settings off, only Gmail syncing and the usual push notifications here and there. Nothing too fancy or strenuous.
Any help on how I can go around fixing this? I'm a little afraid to rooting/flashing/ROMs etc, because I've no clue what works best.
Cheers!

If your saying you left the screen on over night, meaning the phone never went into deep sleep.. If you slept for let's say 6 hours and the phones screen was on for that whole time it's normal that it went down to sixty percent battery.
Maybe I'm understanding your post wrong? Btw I cannot see the picture you posted.

Turn off mobile data and lower the screen brightness to 0 during the day. Also disable WiFi when you're sleeping. I also make sure all apps are closed using the app manager button on the far right.
Mine's been fine following this logic.

Oh sorry, I should meant sleeping overnight, whilst I slept cosily in my bed.

This is NOT the answer. His battery in the image has dropped 7%. If he hasn't used the screen much it is perfectly understandable that screen might not be a large percentage of that 7%. As he uses the phone more screen will use a larger percentage of his battery and Android OS will use less.
If he gets to the point where the screen is on for an hour or two and the percentages are still like this then yes there is a problem.

Actually No the "Screen" should not always be at the top of the stat list. If you use the phone more than it idles, then yes... but if you are like me, mine says "Phone Idle: 20%" (which is on top) and "Screen" is 4th on the list with 12% (Wi-Fi and Cell standby above it) [this is my personal phone, and I mostly use my work phone. hence the high Idle & standby]
I was having an issue with my phone running out of battery, with very little usage from it. I mean very little, I might make 2 calls from it each day, and respond to an email now and then. I found that an App was preventing my Screen from going into "Deep Sleep" or even "Sleeping" possibly. So I uninstalled all apps (well I only had like 4 additional apps installed), except for 2 that I need (Google Voice & Drive). Powered off the phone, charged it fully, then powered back on. Its been running on the same charge for 24+hrs now and reads 68% battery remaining.
So check the apps you have installed, some use background data, and might be causing problems...

And your phone is the definitive guide for what Android OS usage is? Maybe his phone woke up those services for a period of time longer than normal.

See now it is much easier to see that you actually do have a problem and what it is. You have the wakelock problem as you can see from Better Battery Stats which falls under Android OS on the other screen. It also appears that you have somewhat weak signal which could cause the wakelock to drain battery even more. There's not much you can do about that wake lock, some kernels have patches for it but those have their own issues as well.

Could I just install any kernel on stock android and be OK with it? As I've said I've no idea what's best for me; just something nice and clean that doesn't have issues like this. I live onsite where I work so my WiFi is pretty much on all the time if that helps in anyway whatsoever
I'm gonna let it run down completely tonight and charge it, but I don't expect it to help much.

The battery on the n4 seems horrible.
I'm completely stock I just got my phone yesterday, I charged it to 100% now its at 64% battery with only 47 minutes of screen on time.
on the s3 I would be around 83% with 47 minutes of screen on time.
I'm gonna unlock the boot loader and root soon and try Franco kernel I've been reading good things about it.
Sent from my Nexus 4 using xda app-developers app

The battery life on the stock kernel isn't great because the CPU management isn't optimized well. It ramps up the CPU (frequency, number of active cores...) very easily and keeps it there long, which removes the occasional lag but sucks more battery. Flashing a more battery friendly kernel would definitely help you if that is the root of your battery issues and not a badly coded app.
Franco's kernel is a very popular one, and very battery friendly compared to stock (and that doesn't mean you lose performance). It is the one I'm currently using. Most people report of screen on times of 4 or 5 hours. With not so heavy usage and wifi (not 3g) I can also pass 5 hrs.
To install a kernel you need to unlock your boot loader and install a custom recovery. No need to root, but.. why not since you're at it
You can try different kernels with the stock ROM. You don't necessarily need a custom ROM. Just be careful to read the dev's OP and instructions, and definitely not to flash a kernel for another device.
Also another thing that reduces battery is your mobile data, if there are a lot of programs that sync on the background. You can use a program that turns off your mobile data when your screen is off and switch it back on just for a sync every xx minutes. Juice Defender is such app, though I like to use Tasker for that. If you use Tasker and are interested in that project, ask or send me a pm. It works great.

[Q] Bad battery life

Try going to 4.2.2 and see if that helps.
If your still having the issue, it's probably something wrong with your hardware (battery).

Thanks for the reply, I was hoping not to do that, I have flashed slim ROM now, see if this helps, do you think it could be because I stream music from cool Google play music ?

Usually bad battery (especially when it happens out of nowhere) is due to an app causing drain. There are apps that tell you what's eating battery (including the built in meter), the best of which is Better Battery Stats, which you can get for free from the XDA thread.
Sent from an N4 blessed with AOKP and sanctified by Faux123!

yup, majority of the time its an app(s). battery life mostly has to do with your setup, the apps that you chose to install, things that check for notifications in the background, and the way that you use your device. take control of your apps, and their/your setup, and your battery life should be good, no matter what rom/kernel youre on. greenify is a good app to help you get control of your apps.

Check your cord if its faulty, I had a faulty stock cord before telling me my phone was at 100% and when I unplugged it and used it, it went down to 50%
Changed cord, everything was fine.

Do you use a wireless charger? For me 90% of the time it creates a wakelock that won't allow the phone to go into deep sleep. That will hurt battery. If it releases that wakelock or I reboot my phone battery life is phenomenal.

The best you can do is to post a screenshot as someone said before. Besides of this, if you have Google Services/Android System battery drain, you can go here:

Hope it helps.

Something wrong?

I've tried a large amount of ROMs by now and I'm cosistantly having these issues with my battery. I'm noticing a correlation between battery and WiFi seeing that WiFi destroys it every time I use it...is there something wrong with my phone? Battery? Should I stop using agat and ktoonz kernel? I'm confused...I'm not OCd or anything with my kernel either

If you have a battery monitor (such as GSam or BetterBatteryStats, etc) take some screenshots and post em' so we can get more info.

Yes, I noticed that WIFI kills the battery life too. That probably because, it constantly scans to try to find and connect to a hot spot of TWCWIFI. I have to make sure to turn off the WIFI after use.

Hmmmm. There are a number of rooted apps that will kill unnecessary apps from sucking the life oitta your battery.
Use Greenify. Its a pretty cool app that deff helps out.
Obviously make sure Power Saving Mode is on. Make sure to turn off anything youre not using.
ALSO. Something many people don't know...Whenever I get a new phone and or battery. I make sure..and this is important...I charge the battery ALL the way up without messing with it. Then when its good and juiced up. Use the battery normally. But use it ALL the way til your phone dies. Literally. Then...charge it ALL the way back up.
Repeat these steps a good 3-4 times. Batteries have memory in them. If you charge up a new battery to say 75% and take it off and let it drain..then charge it back up. It'll think that 75% is 100%. Thats why its crucial to do those steps a good handful of times.
I guess you can also set your brightness level to auto. Get a cleanup app. Clean Master is a good one. It even boosts memory too by clearing up random files.

I tried greenify but like as we speak, I'm on the charger with WiFi on and the battery is still draining....like is my phone screwed up?

Yes, you should. I am always amused that people will take a perfectly good device, modify it completely, and then wonder why they are having issues. ODIN back to stock rooted and don't fix what's not broken. Needless to say, I have no battery drain issues with my device. On my old S3, I used to do what you do, including running kernels by the same devs you mentioned. What I found was that I would spend hours backing up, flashing, restoring, configuring, etc, and I would be left with a device that ran like crap with piss-poor battery life. Nothing custom lasted more than 48 hours on my old S3 and nothing custom has even been flashed to my S4. No need for it.
I do notice that sometimes I get more WiFi battery drain than even on LTE. That has to do with the signal strength of the WiFi vs LTE. A weak wifi signal will drain your battery more than normal, that goes for any device.

Give us some screenshots brotha so we can help diagnose the problem.
