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 .

Generally. I allow that there are some that are not battery hogs. I do know the chat program on my Touch Pro (I forget what it was) would suck my battery dry in an hour or two if left running in the background.

networklocationlocator wakelock

Hi,
Hope someone can help because I'm pulling my hair out over this. I am seeing pretty terrible battery life on my nexus 7 ranging between 3 and 6 hours screen time over a day or two. The culprit is pretty obvious as reported as Google services in battery usage and I can clearly see obscene partial wakelocks from networklocationlocator. This is chewing through battery while the tablet is not in use. I have attached a screenshot of both the standard battery graph and better battery stats. Latitude is not on, I am not reporting location but location services are enabled for Google now etc. Please help. I don't want to have to cripple Google now to solve this issue.

No suggestions at all?

Does this show up under your regular battery stats? I would try to help by offering a comparison, but I have no interest in spending $3 for a battery stat program like you're using.

I'm having similar problems with mine.. poor battery life, and I seem to have almost the same partial wakelock issue, except on the top of my list, I have AudioOut_2, which is really weird, I have no idea what that does. NetworkLocationLocator is the 2nd on my list..
I also have very low screen times ranging between 3-6 hours, way below Awake time. which means its doing stuff in the background..
My regular google battery page looks like yours. Wish I could help.. I will investigate some more.. do some tests.
Ive been thinking of doing a factory reset..see if that helps anything.

I was having the same issue, though the only thing I realized I didn't check was my Google Now settings. Go in there to make sure one or more of the cards aren't GPS happy.
I turned off a bunch of them, and will check again tomorrow to see if that does the trick.

In Common.
My issue is IDENTICAL, this is really a big time problem I hope there is a solution to. I don't have a Nexus 7 tablet, but a Verizon Galaxy Nexus running 4.1.1. This is a Jelly Bean problem. I unplugged my phone from a full charge, turned the screen off, and woke up to 66%.

Terrible battery life

Hello everyone, i purchased my Nexus 7 and it arrived in the mail 3 days ago. And as with every other Android device ive ever owned, the batter is absolutely terrible. I get about 2hrs on screen time when browing the web and maybe playing an occasional game. Does anyone have any idea whats going on? Or have any way to help? Thanks so much

That is pretty bad. Try a factory reset. Might be something you installed.

I'd hate to do a factory reset cause I just barely got it set up but..I'll try it anyway tonight

Doing a factory reset before installing anything is becoming the gold standard.
Hope it helps you.

I get between 7-9 hours of active use. Sounds like some process is running amok on yours. I didn't factory reset when I bought it either....though I have rooted it since then, but battery life is about the same pre and post root.
You might want to consider a program to monitor battery use to see what's eating it up. Maybe do that before you factory reset it so you don't install the same thing again.

System panel is a good app to find what's using your CPU and better batterystats can help find what's keeping your phone from going to deep sleep. An easy way to see if this is the case is go into battery setting and select the first option(history details). Compare the Awake bar with the screen on bar. Those two should be nearly identical if not then you have a rogue app.

have you flashed any kernels or roms? sometimes this makes the tablet report the wrong battery stats for a bit.
did you run the battery down until it turns off and then give it a full charge? sometimes you have more juice than what is being reported. ive been stuck at 1-2% for over an hour before. Most likely its a rogue app though, system panel and better batterystats should find out what app it is. if they dont then it could be that you have a defective battery...

Been on mine continuously for 3 hrs 18 mins and at 60%. Excellent if you ask me. Next step up in battery life would be Transformer series with dock.

Quite the opposite for me; unlike every other Android device I've had (Nexus One, GS2) the battery life is excellent. I watched 720p mkv video on the train yesterday for a good 3 hours, and still had ~70% by the time I got home, from a full charge.
The battery life is excellent, as far as I'm concerned.

Don't think you needed to calibrate the battery to begin with. I usually get fine battery life without doing anything special.

Something must be causing the poor battery on your Nexus, Yesterday after my N7 was fully charged, I watched the movie Thor for 1hr and 54 minutes n and my battery only dropped to 83%.

I'm at 16 hours and 52 minutes with 3 hours and 44 minutes of on screen time, the battery is at 51%

My N7 is completely stock and has never been rooted. I also did do a couple charge cycles which didn't seem to help much. And better batterystats has AudioOut_2 at 38% (while I'm playing music) but other than that it doesn't seem to be a rogue app

Unless you listen to music for over 5 hours or streaming the songs it shouldnt use that much battery. If you can't find a wakelock with better battery stats then it might just be a bad unit.

Battery drain behavior

Hello,
Just trying to figure out if my battery is normal.
With any ROM OR KERNEL combination here, I tried few, my battery is fantastic while phone is idle, no loss over night or all day if screen is off.
But once I start using the phone it drops like 3-5 % from few minutes regular use, yesterday I took few photos, sphere, panorama and it dropped 25%. I have max1350
Wake locks are OK, no stupid stuff eating at it.
Is this normal for people or?

Nah, that's not normal.
- Bad signal reception?
- Google Now & maps updating non stop? Other apps, like facebook?
Post a screen shot of your battery usage graph, will make it easier to determine.
Have a look at this thread as well http://forum.xda-developers.com/showthread.php?t=2107163 some people have been helped by flashing back to stock.
Was it always this bad?

The battery reporting is kinda broken. Add you say, it can hold constant when it should really be draining slightly, and then suddenly drop in one big go as it "catches up".
It's a common problem.

-I was thinking of signal, I think it's not so great at home, it jumps from 3g to H to H+, but it's like 4-5 bars. Not sure, is there an app to monitor the signal strength?
-I've been planing around so there are not solid stats yet. But I am running Liquid smooth I don't even have Maps. There no crazy wakelocks or apps running, otherwise even in idle mode I would loose power.
It pretty much been always like this, since I started flashing custom staff. Don;t remember on stock, as there is no batter % icon there, I reverted back to stock right now lets see.
What ROM/Kernel are you using? and have you done what that thread is talking about?

Yes pretty much, I would not say i drops in one big number, but yes fast so pretty much same.
For example, to post the Thread i went from 35% to 32% after being idle all night, but then One Hour Driving to work with BT on pair with car, text messaging and e-mailing it dropped 1%.
The big question, if it's common problem, meaning not on every phone, so does t hat mean it's hardware and I should be calling Google?
or
is it 4.2.1/Custom ROM/Kernel problem?
is there a thread or anyone I can follow on this issue?
Thanks

I was on that until yesterday. Try it with Trinity or Franco's kernel, see what that does.
Didn't do what the op claims in that thread but then again, I didn't have any issues with the battery..

My phone was behaving the same way. The idle time would be great...no percents dropping for hours. But then when I'd actually use the phone the drop was sharp.
Lately its getting better for me...its dropping a bit on idle but also at a much slower rate when the phone is used.
I hope it'll be fixed in 4.2.2
Also keep in mind that the rendering process in photosphere does that huge amounts of battery.

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.
The answer of "lol looks wrong root and install kernel" is terrible advice when so little information is given.

A longer battery graph would help a lot. If yuppy want top search XDA there is a free app called better battery stats that will help you diagnose if something is running in the background eating battery or even if your phone I'd properly entering deep sleep.

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.

Idiot question; will installing a kernel just solve this? For now as a new guy I'd like to keep it as stock as possible before fiddling with it.

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.

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.
