[Samsung Galaxy Nexus] Icey34:
Hello everyone.

So I bought this phone this past Friday and been having a blast with it. I bought the 2100mah verizon/samsung extended battery yesterday to have a bit better battery life with it. I have patience with battery life, so I'm ready to try anything.

Here's part 1 of my post (radio): So I'm on 4.0.4. I have the radio that comes with it. I noticed I can only get 1-2 bars (rarely 3) of signal at times. I read that the best way to post about this is in dBm so here are mines: -100 to -120 80% of the time. This is on 3g/4g/wifi. And it's rarely on 4g, it is always jumping to 3g. My mom has a thunderbolt and to test, I saw the thunderbolt had better dBm and always had a 4g signal, 3-4 bars constant, rarely 3g. I'm in Miami, Florida if it matters, which is a strong 4g area. When it's on 3g it gets very good signal, 3-4 bars and -80 dBm. Though sometimes I noticed my wi-fi gets 4 bars for like 10 minutes and returns back to 2 bars.

Anything I can do as far as the Radio, some people have fixed it with a new sim card but before I go get one (are they free?) let's see what I can try? Perphaps a new radio?

Part 2: Alright now as for the battery life. Here are my phone "stats": (screenshots are posted at the bottom of post for battery)

-4.0.4 Stock ROM nothing changed, just an unlocked bootloader.

-WiFi on when at home, off when using 3g/4g.

-NFC On.

-No syncing, everything updates when I open app (twitter, weather)

-Gmail is set to push, atleast I think so. It notifies me of a new email every time.

-48% Screen Brightness

-Signed OFF from Google+

That's it I believe, if anything else is needed let me know.

I have the XDA version of BetteryBatteryStats, so I guess I have the tool to fix it just need to pinpoint what the problem is. I'm draining at 2%-3% per hour with wi-fi, and no usage, just idle. Again this is with 4.0.4 update. I'm seeing people's battery life becoming awesome with some tweaking, so would like assistance on that.

Here are my screenshots:

Day 1 with ext battery on 4.0.4:

Have you confirmed that you have the new radios installed?

I515.09 V.FA02 / I515.FA02 (or could show as I515.10 V.FA02 / I515.FA02)

You probably did that, but just wanted to be sure.
[Samsung Galaxy Nexus] Icey34:
I have: I515.09 V.FA02 / I5I5.FA02

I appreciate the help! :)

CDMA Input

So what have others found about CDMA battery life?? Mine is poor no matter what ROM or Kernel I seem to try to run. I also have attempted under voltages in SetCPU to see if that helps. Any feedback is greatly appreciated. Peace.
[Samsung Galaxy Nexus] KWKSLVR:
You need to define "poor". Everyone's use is different as are their apps. If you truly have poor battery life no matter what, look at the three things that are always probably the same. 1) Your physical battery. Is it defective? 2) The apps you use. Perhaps you have an app that is acting up and syncing like crazy or wasting CPU cycles. 3) The area you live in. Do you have poor signal strength?

The biggest drain on your battery is ALWAYS going to be your screen, and data/sync. In my personal use, my biggest drain is: Screen Brightness 100%, Netflix running, Audio 100% through the speaker. This equals about 30% per hour with the Verizon Extended Battery depending on what all else syncs in the background...with a live wallpaper.

Undervolting is a misleading thing. People will disagree with me, but when you look at power consumption tables, undervolting does very little. When our phones display battery % remaining, it's not based on the actual juice left in the battery. It's a calculation based on charts that the phone manufacturer (probably Google in our case) took from the hardware manufacturer and put into play that basically says that at this Processor Speed (X), this Level of Power Consumption Occurred (Y). It happened for this Amount of Time (Z) and then it compiles that data and solves for an amount of power used giving us a percentage of remaining battery life. In general, this is VERY accurate. However, there are no values programed in to account for undervolting...or OVER clocking for that matter. For example, if you're overclocked to 1350MHz, then Android is going to use the values for 1200MHz. If you put a timer on your battery life, you'll see a longer run if you run your phone until it shuts itself off. But it's not THAT big of a difference. All the while when your watching how quickly your battery bar drops with your use, you can't see a a measurable difference.

In my experience with undervolting, doing so got me maybe an extra 5% boost in battery life. I can't equate that to a time because again, usage is different. In general, a 5% swing in a charge cycle can be easily accounted for by other things. Does your processor use more juice @ 1200MHz with normal volting compared to 1200MHz undervolted? Absolutely, but undervolting isn't going to get someone hours of extra battery life, especially when our screens usually account for 60%+ of our battery consumption. All said and done, undervolting results in gaining us very few percentage points in terms of what percentage of battery life our processors consumed.
[Samsung Galaxy Nexus] photolarry:
Seems like the kernel and rom do make some difference not just apps. I use AutoStarts to prevent a mess of them starting upon boot. I am sure the screen takes a ton of it. But I am convinced that it depends on voltages and kernels too. Since I notice differences.
[Samsung Galaxy Nexus] Icey34:
Ok KWK, but there's a trade off here. If I try the 4.0.2 radios, that some people reported bad battery life on, it's just because it had a bad trade off for SOME

people right? So that means 4.0.2 radios could be good for me and result in better battery? Can I be on 4.0.4 and have the 4.0.2 radios?

Anyone know where to find these 4.0.2 radios and how to flash?

As for the battery life part of my post, what do you guys think I should try doing in betterbatterystats? A recent thread on here: http://xdaforums.com/showthread.php?t=1483829&page=3 (Go to page 3 and last post) He got his life fixed. So that's nice to know there's tweaks that can be done. Any suggestions? Look at the http://xdaforums.com/showthread.php?t=1488680&page=6 thread too. "draining at 1% per hour in sleep mode & how are you doing it?"
[Samsung Galaxy Nexus] photolarry:
I disagee with your comment about old 4.0.2 radios since 4.0.4 (FA02) radios have improved signal reception. It is possible that maybe it affects battery, but I kind of doubt it. Based on all the research so far, seems mostly screen eats it a lot as well as how you use all the apps on the phone as mentioned above. I mean isnt this a matter of some electrical engineering info (ie voltages etc) and how to tweak such things? I have CS degree but admit my hardware knowledge is not greatest.
[Samsung Galaxy Nexus] Icey34:
Ugh, I'm in a mess now, lol. I called Verizon yesterday and followed their usual "signal solution" got me to 4 bars of 4g. Turned on WiFi - 2 bars, turned it off, back to 1-2 bar 4g that last for 30 seconds.

I'm starting to think it's the sim card.

Any suggestions for battery life? Seems my phone can't sleep. It's down to 83% after 5 hours. And all I've done is send 2-3 text messages. Do I turn off NFC for a start?

edit: Now I'm at 4 bars wifi. Goddam radios, they are so random, we'll assume the phone is trolling and continue to the solution.
[Samsung Galaxy Nexus] Icey34:
bump for the night scary how fast it got to page 2.

let's get these issues fixed! :)
[Samsung Galaxy Nexus] KWKSLVR:
If your phone is searching for signal, then your battery life is already sucking it up. A "stronger" radio that uses a little more juice won't cause more drain than your phone will cause by throwing everything it can at the phone antenna. Just look at my screen shot from before...28% battery drained in 8 hours...an additional 20% due to the phone trying to keep a signal.

Like I said about your original screen shots, your battery life doesn't seem to be that "off to me". Just push different radios, and try them for at least a day. ;)
[Samsung Galaxy Nexus] Icey34:
Okay will do. Where can I find these other radios and how do I flash them?

Lastly, anyone here an expert on fixing phone isn't sleeping? Seems to be my major idle battery drain.
[Samsung Galaxy Nexus] mutelight:
You can find the radios here:

http://xdaforums.com/showthread.php?t=1481095

If you have the 4.0.2 radios, you can flash that ZIP in Clockwork Recovery Mod.

It will take a few minutes so leave it be and don't do a battery pull.
[Samsung Galaxy Nexus] Icey34:
Well I have the 4.0.4 radios, does that change anything?

edit: after looking at that link you provided, are those even radios only? Seems like a bootloader & radio update from 4.0.2 -> 4.0.4. And I'm already on 4.0.4. But with horrid signal.
[Samsung Galaxy Nexus] mutelight:
I have had the best results with the 4.0.4 radios but you mention you are already on them.

You can try flashing some older radios but I am not sure that will help your signal issues.

As far as finding out why you are having deep sleep issues, you can use Better Battery Stats to narrow down wakelocks.

With that said, if the phone is constantly in an area with poor signal, that will cause unnecessary battery drain as well.
[Samsung Galaxy Nexus] Icey34:
Where can I find these older radios?

edit: I'd like to try the 4.0.2 radio.
[Samsung Galaxy Nexus] Icey34:
Update 1: So today I powered it on after having it off from 7:00 AM to 2:45 PM. It's been idle, checked email for replies on this post and this is my battery:

Something is eating up it's idle time.

I noticed on the way back to my House it picked up a strong 4G signal for 5 minutes or so. Still looking to find where the 4.0.2 radios are. Noticing a stronger WiFi signal though, and the usual 4bar 3g. All I can find is the post from adranalyne about the radios from 4.0.2 -> 4.0.4. Something I was thinking about: If I flash 4.0.2 radios, say they are bad and I need to go back to 4.0.4 would that require a whole new flash of 4.0.4 or are there seperate radios?

Here are the betterbattery screenshots: (I have for last unplugged and charged not sure where it needs to be)
[Samsung Galaxy Nexus] Colemak:
I too have an LTE Galaxy Nexus and have been switching from franco's and lean kernel in an attempt to gain battery life. I have a feeling you're not going to get much better battery life with LTE turned on. I've turned off sync and LTE overnight and the best I've gotten in deep sleep is about 1-1.5% an hour. That's all after hunting down all my unnecessary wakelocks and shutting them down (GTALK_asnyc, etc) and keeping my running programs to a minimum (email, lightflow, and weather1 are the only ones ever running besides stock apps with sync on weather1 on a 6 hour cycle)

All of the two day battery life posts I've seen all seem to be GSM phones, and typically I've been getting a full day pretty comfortably...

8 hours while sleeping + 8-13 hours of light to moderate usage (1-3 hours of screen time generally)..all with about 10-25% remaining at the end of my long days
[Samsung Galaxy Nexus] Icey34:
That's excellent. But one problems: (1) I can't even get a 4g signal, at most for 5 minutes in an area that I regularly get it. I have a thunderbolt next to me running 3-4 bars. I know the GNex has a bad radio, but sheesh I atleast want to have SOME 4g.

Been trying to find a radio, can't find one though, if you can link one that'd be appreciated.

Anything you see there in betterybatterystats I should shut down, and do they start backup after boot? I see the GTALK thing you were talking about on mines too, how do I get rid of it?

edit: just a few hours after my first post today:

Thanks, I've been wanting a newer external recovery image.
[Xperia Play Android Development] KeiranFTW:
Your welcome :)

I also edited the keylayout in my CM sources for recovery so that we can use the four hardware buttons efficiently, back button = back, home button = up, menu button = down, search button = select.

I did this because on the new CWM the layout is all messed up for our device :)

[Xperia Play Android Development] bamsbamx:
Could be possible to flash it through terminal emulator??? (without pc... :D)
[Xperia Play Android Development] KeiranFTW:
No flashing....

And you probably can't boot it through terminal emu either.
[Xperia Play Android Development] bamsbamx:
Why not??? I have tried to write: su fastboot flash...etc and it answered: not found..... But it seems to be possible to flash.... I dont know why it wouldnt boot....(have unlocked btl...)

Thanks for your answer ;)
[Xperia Play Android Development] Atarii:
No it's not possible to flash as the Xperia range does not have a recovery partition, which is where you usually flash the ClockMod Recovery to
[Xperia Play Android Development] Leraeniesh:
Could you possibly update this to the newest CWM?
[Xperia Play Android Development] nickholtus:
i will try to update it, as it is not that hard to do:)

[Desire HD Q&A, Help & Troubleshooting] zamook:
Hey all,

I'm using this type of cover (please see attachments) for my DHD, been using it for the last 3 months.

however, some friends warned me that the part of the cover with the magnet, that lets it stick closed, will be of harm to the front Speakers.

So I thought I'd ask the experts here at XDA. :D

Would be useful if anyone faced such issue, share his experience.

Thanks.
[Desire HD Q&A, Help & Troubleshooting] GuyInTheCorner:
Im no expert but I have the same cover in black since I got the phone and I've not had any problems at all
[Desire HD Q&A, Help & Troubleshooting] Outback_Jon:
The magnet in the case should cause no harm to your speakers.

The only problem I've ever seen from a magnet in a case was on my LG ENv phone. The phone detected when it was open through the use of a magnet, and the magnet in the case would give it a false reading, causing my phone to always think it was open. This lead to VERY fast battery drain, since the screen was always on.
[Desire HD Q&A, Help & Troubleshooting] bbawden:
I don't see that this could be a problem, but I suppose you could always put the phone into the case upside down if you're worried.
[Desire HD Q&A, Help & Troubleshooting] zamook:
I think I shouldn't worry then,

Thanks for replying.

Haven't thought of that before :)
[Desire HD Q&A, Help & Troubleshooting] f_E_a_R_e_D:
I agree, unless it was a high powered magnet u should be fine

I don't think so... it could consult with Vending.apk about the license status, which would fail because there would be no account present. Removing it would prevent it from saying not authorized -- though the API for it might stop it anyway if it can't find the market.

Ok folks.. can I complain about this one?

Posts like these.......

You really expect us to help you when all you post is "how do I fix lag?"

How about, what games are causing it, which model do you have, how much free space, what type of SD card. Are you rooted? Are you overclocked? I could continue for an hour on this line of questioning.

Do a little actual reading on the forum here, then repost your question when you know what to ask. We aren't mind readers, and we certainly aren't Sony tech support.

My mom got the epic 4g touch and I didn't really like it. But no problems really that ive noticed. But I never got to mess around with rooting it/the programming side of it. I'm honestly thinking of going to iPhone because its not as fragmented as android.
