I got a DINC with CM7, radio 2.15 and 2.6.38 incredikernel.
I personally felt battery drain was bad for the phone, the problem is that I had a kind of similar problem with Droid X devices. I am starting to believe it has to be with my carrier, but well I'll let you guys decide.
I flashed this rom, radio and kernel, because I read of battery draining issues. But I still feel is a huge battery drain for me with 3G on.
I have to keep disabling and enabling my 3G only when I need it, when I have seen other phones with 3G always on lasting about a day.
Just to give you an example, I wake up in the morning, unplug it, turn on 3G, listen to a radio station with screen turned off for 30 minutes, turn the screen on and battery percentage goes 20% down, so I'm left with 80%.
That would mean, if I listen to online music for 3 hours online, my phone would be dead.
Is this normal for you guys?
I appreciate any comments and experiences, thanks.

Streaming is battery intensive, you are basically downloading the entire time.
I have to say battery life is one of the most subjective aspects of smartphones let alone android devices. For one, your signal strength relative to nearby towers will affect battery drain. Secondly, everyone uses different batteries ranging from stock to extended so there is little consistency. Our phones with the stock battery do not last longer than 3-4 hours with 3G on, so what you stated is not unusual.
From what I remember, of the droid phones that came out last summer the Droid X and Evo 4G are said to have "better" battery life fresh out the box compared to the Incredible and that's maybe by an hour at best. You should expect to see a lot of "use wifi" or "my battery life is impeccable because of ..." type posts in response to yours to be blunt.

First of all, I'm not in Verizon, it's actually a mexican carrier.
I do understand 3G is very battery demanding, I just do not understand how is it that you guys can last a full day with 3G, I've never or heard very little of users turning off their 3G so it can go for at least a day.
I mean, if you guys run a quick test for 30 minutes of listening to some radio station in 3G, could you see if your battery drains really quick?
I've seen GSM users with 3G always on, and they never ask for a charger like I do.
I'm always looking for ways to charge my phone and they just go all day without a charger.
It makes me feel bad haha.

I recently did this after updating from stock .28 radio to .07.07 and have noticed a HUGE battery life improvement. I understand that these results vary quite a bit but beforehand I was experiencing what you describe: big battery drain while 3g was on at all. Also running stock+ 4.06.605.3 ROM by jermaine.

I last a day and a half with 3g consistantly on. I am not running a sense rom though. I've found sense rom's drain battery a lot faster due to how many Widgets are used and constant syncing. If you can I would try an AOSP rom and see if there is a difference.

That is completely normal for a CDMA based device. GSM based phones suck power at a fraction of the rate per MB downloaded because signal strength isn't linked to the broadcast power required. Broadcast power is static. I've seen my dInc go flat dead sitting on a table inside 4 hours. In ideal circumstances, it might go 8 or 9. A GSM devices utilizing data on the same levels will achieve uniform battery life regardless of signal strength and outperform CDMA devices on battery life by twice, if not triple the time. However, CDMA will provide higher data rates. LTE is unquestionably the most efficient megabytes/watts used. To perform the same function on an LTE device (your radio app), it would have consumed between half and a quarter of the power. A GSM device would have been about half the power.
3G electric charges
I know what the OP is talking about. I had DInc1 running OMGB, and it would last 10-17 hours depending usage with 3G on all the time. Now, I have a DInc2 running Condemned CM7.2 v1.6, but it can only last like 8 hours idle with 3G on. If anyone has a solution to this, it would be nice to know. I also tested if it's 3G by turning off mobile data; without 3G, the phone lasts a long time, so it's not an app or battery issue.
Hey, im on Telus so i dont have any other modes I can switch to to lower the drain. Ive noticed my battery drain is HORRENDOUS
Over the past 4 hours ive dropped 60%!
Now im wondering if im just running too many apps or if my stock battery may not be holding a proper charge anymore, and wanted to compare with others to see if others are running the same amount of apps and getting better battery or what
Ive got the following on:
Trillian (IM app)
K9-mail checking 2 aps
Regular Sync (Twitter, FB, Dropbox, Google(Calendar, Gmail, Contacts)
The battery usage summary seems to lie, 35% is the screen but only 13 minutes. Yet im at 40%
Android System at 20, Cell standby 13, Phone Idle 8
While heading to work, i ran DI Radio(music streaming), and lost 20% over around 35 minutes.
Im using the Tuesday rom with it's default kernel.
Is there anything I can do for better battery, because I dont have wifi in most places, and im running 3-4 bars constantly yet the phone just drains rentelessly. Even my Mugen battery was only lasting 16 hours...
It's quite possible that it's the ROM. I used to always get 8 hours on a single charge, regardless of location or ROM. I'm running Eugene's CM7 and I'm getting 13 hours on the same typical usage.
I'm running on Telus as well, with no wifi at all.
Although I am not running all of your apps, I would still consider myself a moderate to heavy user.

any syncing or usage of the network will take a drain. any usage.
you can always turn on airplane mode and let it sit a few hours and see the drain, that determines whether its network or a ROM/kernel drain.
But yes, using 4G has big battery cost
Battery Life
I will tell you what, I have wasted so many hours playing with different ROM's and what not to find the one with the best battery life. And I will tell you what, the DARKSIDE:IGITAL::WARFARE ROM's out do any other ROM out there. I dunno what it is that thederekjay is doing, but Samsung should get this guy on pay roll because his work is the best.
I'm at hour 8 today on Darkside Digital Warfare, and 70% free from 8am to 4:30pm. I have push corporate email, automatic brightness, friendcaster push, and a slew of accounts and it runs like a champ with amazing battery.
Make sure your phone is going into Deep Sleep as often as possible when screen is off. My phone seems to be extremely picky in regards to which charger it likes and more often than not (even had this happen on the stock charger) the phone refuses to sleep after being charged (even if only for a few seconds...).
Download CPUSpy from the market and after each charge, go to CPUSpy, press menu and Reset Totals (phone cannot enter Deep Sleep during charging so it's important you start fresh after a charge to get accurate sleep time). Turn the screen off for a minute or two and turn it back on. Press menu again and Refresh Totals. In my experience, if the phone is not sleeping at this point - Deep Sleep showing in Unused States - then it will not sleep all day and remain in 384Mhz for hours, killing the battery rather quickly. From then, if I plug the phone in a supported charger (even for a second) and disconnect, Deep Sleep resumes normally. Rebooting always fixes it too.
If, like me, a lot of people also have this problem with the stock charger as well, I bet many are dissatisfied with the battery performance... The phone is supposed to spend the majority of it's time in Deep Sleep. I get this issue with several different chargers and cables and on different ROMS / kernels (including stock... go figure).
Im pretty sure its the signal itself draining it. It uses sleep for at least 40% of the time its on. I use my phone a good amount, but its the fact that if it sits on 4g even with the screen of, its rapidly draining during this time. ive even reset timers and left it sitting for an hour and itll be in sleep but lose 8% over an hour just doing nothing. I still wanna be able to recieve notifications tho so turning off data isnt an option. I will test turning off data anyways to see if the drain stops.
The battery drain is all those persistent internet apps running. That is what you call heavy usage. Trillian and the FB app being the two biggest. Music streaming would be up there as well if you aren't in good signal area. Look at your battery stats and see what your signal strength is.

My wife and I both got new Verizon Galaxy Nexus phones about two weeks ago. Having heard of the poor battery life, I immediately bought an official Verizon extended battery; wife stayed with the stock one. After both of us set up our phones and went through a few charge cycles, I noticed something odd: while her battery would last 24-36 hours with mid-level use, mine would die within 9-12 hours with minimal use (it has never made it overnight).
My first thought was that some widget or app was syncing or otherwise waking the phone when it shouldn't, so I removed all the widgets from my homescreens and disabled all syncing but Gmail, Google Calendar, and Google Contacts. I also turned the screen down to minimum brightness. Still had the fast discharge issues.
Next step: uninstall all apps that I've downloaded. Battery still drains too fast.
Finally, I did a factory reset of the phone, and did not download any new apps. I thought maybe there was some deeper setting that I had overlooked that was causing the issue. After the reset, the battery had its worst performance yet at ~9.5 hours with bare minimum use (mostly overnight). Wife's phone was still going strong with about 34 hours of usage.
I am in wifi coverage all day (except when driving to/from work), so I have kept that on. Bluetooth and GPS have been off the whole time. Average time without signal is ~2%. 4G is also on. I also tried 1-2 charge cycles with the regular battery to make sure that it wasn't just a faulty extended battery, but it predictably resulted in even worse discharge time.
I have kept track of the battery usage stats both in the standard Settings as well as Badass Battery Manager, but nothing has seemed out of the ordinary. Right now I am charging up my wife's standard battery in my phone, and she is using my extended battery, to make double sure that I didn't just end up with two bad batteries.
Both of us are using stock ICS 4.04, and are not rooted.
She uses her phone for Google Talk, Facebook, Tamadroid (Tamagotchi app), etc. throughout the day (don't have more exact usage stats at the moment), while mine has been sitting practically unused for the last few days while I try to see if my various steps work, so the top drainers have been (in order) Mobile Standby, Phone Idle, and Screen On.
Last night when we went to sleep, my phone was at ~70% on the extended battery, and hers was about 14%. This morning, mine was dead and hers had 5% left.
Is there anything else I could have missed that could contribute to this issue? Unfortunately I do not have access to to my actual usage graphs/stats right now, or I would link them. Any help would be greatly appreciated. Otherwise, it's back to Best Buy to exchange for a new phone.
UPDATE: This was a hardware issue. Exchanged phone and saw immediate, drastic improvement. See my last post for more detail:

It sounds like the battery to me. Not all batteries are created equally. The quality of the components is going to directly lead to the discharge rate, degradation over time, etc. It sounds like the battery you were sold sucks and the stock one would probably work better.
I certainly can't think of anything else you can try. It would seem that swapping batteries with your wife for a day would tell you for sure if it's something to do with the phone or the battery.

I am going to swap out the battery at a Verizon store later tonight, and see if it works any better.
To make a better comparison, compare screen usage as it is the big eater of the battery. You should find it on battery usage.

Its hard to say why.. but is there anything wrong with the network on your phone? My brother got one, his dropped signal every 2/3 minutes and the battery lasted at least 4-6 hours, you can also check to see what your phone is using in the battery section in settings.

Got a new extended battery from Verizon, and it seemed to be working a lot better during the day. However, once I went to sleep the charge dropped like a rock! I am doing a new charge cycle with Badass Battery Manager watching over it, and will post pictures when it is done. I have no apps other than fully updated stock apps and the battery manager. This is incredibly frustrating because my wife's phone is not experiencing any issues overnight. It is looking more and more like this is a faulty handset...
Got some usage stats now. Here is the first full cycle on the new extended battery; seemed pretty good at about 1d 5h. Unfortunately, it has gone downhill from there.
looks like your phone was working for a signal alot of the time.
Here are the results from the next cycle; there is already a noticeable drop to just over 22h.

yeah you have terrible signal. your phone is trying to push for a better signal, which causes more power drain.
if you look at your signal graph, you hit red signal, which is near dropped signal range.
This is from last night. After letting the battery completely discharge, I recharged it while the phone was off. It hit 100% around 12:30AM, when I went to sleep. Fast forward to 8:00AM, and the phone has discharged 66%! Obviously, I was not answering calls/texts/etc. during this time.

Yup, he seems to have a lot of horrible coverage in his area or his phone is in a terrible spot where there is hardly any signal.
Test your phone around your town or home.
Your signal should pretty much look like this
I'm usually full bars, rarely do I drop below to three.
If it helps, disable 4g until you need it.. it will saviour some of your battery.

This makes sense, but for that my wife's phone is usually in the same general area and is getting significantly better life. Could the signal difference at my work compared to home really cause that big a discrepancy? I am usually at 3 bars, according to Phone Radio's settings. This would also not account for the massive overnight drain that her phone does not experience 6 feet away.
I installed Badass Battery Monitor and CPU Spy on her phone for comparisons; I will check her signal levels when I get home.

Well I hope its not a hardware issue on your phone.
I've seen way too many people having this issue recently.. .My literally only issue is my screen, its covered in tint. Yellow, red, blue, purple :/ funny I get a perfect hardware phone and get a ****ty screen. Not going to return it to take chances.
Its possible you may need to update your radio - depending on it, for various users it has different effects on battery life and signal.
Anyway looking forward to the results.

The radio would affect the "time without signal," right? Last night (66% drop in ~7.5hr) it said I was without signal for 4% of the time.

Someone correct me if I'm wrong but.. the RADIO should help or make your coverage "signal" worse. If its hardware or just horrible signal the % loss should be a lot higher with normally about an hour of screen on it should show around 20-40% signal loss.
Normally signal loss is around 2-4%.
I would keep an eye on your signal bar "on the status bar" if it drops - plummets to an empty bar with an × then its possible you have a hardware issue. If it don't drop or if it does check the signal loss occasionally to see how much is lost.
If its horrible signal I do suggest a new radio to help you, if you dabble in the radio world.. please read carefully on them. They can cause serious issues if you get a bad download or wrong download "md5 mismatch". At the least harmful it can boot but without any type of signal etc.
Its easy to use but can be dangerous to your device if not handled properly

Mine is 4% loss also. I've never noticed any significant differences in battery life going from the cornfields to the city.
This phone is known for radio issues. It's pretty disappointing but I've just grown used to it.
Which radios are you currently on? Settings, about, baseband. Should say fc04 fc05 if you're on the latest.
Some people have better luck with different radio combinations depending on their phone.
From your battery Stats its like you barely use your phone. Could you show a screen shot of cpu spy?
Would you consider a different rom and kernel?

Assuming you mean me, give me a few hours? Gonna throw on a full charge and wear it down. I'll give my screens of my phone when its near dead, I heavily use my phone. I'm surprised I was on 2hours with half battery after watching videos.

I have the same baseband as this image. I just added CPU Spy this morning. I will add some screenshots of it after my next full charge cycle.
If it is a faulty radio, would it be in my best interest to exchange the phone at Best Buy? I have about another week to do that if necessary.
I'm having similar issues, although it doesn't seem as bad. I'm going to take the chance of exchanging it because I also have 4G dropping issues, because like you said, we've got a week, and I'll exchange the phone as many times as I need to until I get a *new* one without any issues.
Kind of disappointing, my screen seems great.
Well, I just purchased a Note 2 and am still in the "evaluation phase". I really do like the phone, fast, amazing battery and awesome signal. However I am asking this because I ama wondering if I am getting all that I can be from my Galaxy Nexus before I decide to keep the Note 2 for $700+.
For reference I have recently been using the Euroskank CM10.1 releases with Franco's newest kernel and undervolting CPU to approximately the values in the LeanKernel Aggressive Undervolt levels as well as knocking down all IVA and CORE voltage 100mv.
I can generally stretch the Nexus' battery life to 13 or 14 hours, but that's with <2 hours of screen on time. If I am using it a lot 8 hours of battery life is lucky, if not less. This really isn't with any gaming or using it for listening to anything, just genrally Facebook and the internet. I do leave LTE on even though at work I can only get 3G. I have turned LTE off before but honestly I have never seen an increase in battery life from doing so. This goes to signal issue also, at work it will go to 30% or more time without signal and Cell Standby will be the second highest use of battery. I have a refurbed unit from Asurion that is version 10 and using the latest radios for CDMA and LTE. The Note 2 in the same usage environment reported 0% time without signal and Cell Standby was way down the list of power usage.
So, basically I am wondering, am I getting everything out of the Nexus that I can, or should I be getting better numbers. Maybe some of you on here can verify that the Note 2 is actually better for signal etc. or that I am just being delusional. Thanks in advance to all of you!
EDIT: Oops, meant to put this in the Questins section, accidentally put it here, Mods, please move!
No one?
Seriously? Even a piss off would be nice to hear, lol.
My signal is fine, my battery life is like yours (<2hr screen on) even with the OEM ext battery.

Thanks for the reply, good to hear my battery life isn't out of the ordinary. Signal does seem bad on mine though, I am going to call Asurion as this one runs unusually hot, uncofortably hot to hold even.
Yeah, mine gets fine signal, though the current radio firmware that came with the 4.1.1 OTA seems to have a problem hanging onto LTE signal indoors. I'm sure it'll get fixed in the next OTA (hopefully to 4.2.1). As far as battery life, it's what you would expect from an LTE phone...about 2.5 hours of screen-on time, maybe 3 if you're really lucky. Battery life can be affected by so many things like apps you have installed, screen time, cell signal, etc.
One thing I'll tell you, though...you'll find your battery life go up by at least 30% by keeping it connected to WiFi. If you're on a cell connection, your battery is going to zap a lot faster because as a matter of principle, cell modems are far more power-intensive than WiFi is because WiFi is a much shorter-range technology, thus the transmitters don't have to put out nearly as much power. Also, if not connected to WiFi, weak cell signals are going to drain your battery even faster than a stronger signal.
But, as long as you keep the phone on WiFi when you can, you'll find the battery life is no better or worse than most other LTE phones.

With WiFi, easily 15 hours with ~2 hours screen time. With LTE enabled, usually around 6-8 with ~1.5 hours of screen time. I also get pretty bad signal around my city.

Well the Note 2 destroys the Nexus in battery life and signal reception to be honest, but then again a 3100mAh battery should. I like the Nexus and I am trying to get myself to keep it over the Note because having AOSP rocks and so does saving like $850.
I know there are hundreds of these threads but i was unable to find the information that I'm looking for. But my guess is there is no real answer to my question. But i've been wrong before. Please bear with me
Here goes.
I want to know how to maximize the battery when USING the phone. I dont care about wakelocks or sleep time etc.
I am interested in getting to max out the usage time.
For example when I stream radio and surf the net and text. My phone lasts 2 hours with max birghtness. That seems really short.
- I've done all that I know to minimize power consumption with turning off sync, settings, etc.
- I have tasker starting and stopping data during screen on/off.
- I have the phone UV and under clocked.
- I Limit my phone to 3G only, with no LTE
- Also signal is not a problem since I can stream and surf without an issue. With areas with poor reception. I don’t even use the phone really
-*I also have all the chats turned on include facebook, whats app, etc. Once again, phone is awake. and I'm concerned with its ON screen usage battery time.
- I even have the second CPU setting on conservative. (when set on ondemand it drains even faster)
But during usage, its terribly short! What can I do to prolong the life?
The battery was always like this and I dont believe its defective. With regular use, checking phone (once or twice every hour) can easily last a day. But during multitasking usage I notice the drain to be 49-59% per hour according to battery spy.
I know I can uninstall battery spy/BBS to conserve battery. But I'm looking for what some are reporting (4-5 hours of on screen usage time).
Looking for some guru-like advice Thansk in advanced
Personally, I get the best battery life out of the stock kernel of whatever particular ROM I'm running. I stick with tw based ROMs, and I greenify almost everything! I consistently get between 5 and 6 hours of "screen on" time with the stock battery.
You never said what ROM and kernel combo you're using. I know that I get 3 to 4 hours of screen time depending on the apps used and the connections utilized (wifi, signal strength, LTE or H+, etc). 2 hours definitely sounds low though. I'm using stock debloated ROM right now and stock kernel. I have not modified voltage or clocking in any way (yet).

I didnt really notice any improvements on the KT747 vs stock kernel.
I greenify everything except for the messaging apps. But then again, when my screen is on, i want ot be using those apps.

Its in my sig
Stock 4.1.1 JB
KT747
3G good signal.
Using tune in radio while texting on go sms and surfing using chrome with 7 tabs open

You're doing heavy multitasking!! It's going to eat the battery, sorry, but no one's going to post a magic "cure" to increase battery life! Buy an extended battery... Problem solved.

Websurf and radio or text and radio is just 2 tasks occuring.
Well I can say that running on Wifi, I can get regular battery life about 4-5 hours of use and over 20 hours of idle time.
The radio seems to be the main culprit, so the question is..... what can be done about that?
I'm asking because
- I flashed diff modems and seems to yield same results
- other S3 from my friends seems to last longer with multitasking
- signal....strong or weak seems to produce same drain.
Battery?

I've had the same problem. I couldn't get the same battery life as others I know. I always turn my GPS off if I didn't need to use it. Google now seemed to kill my battery so I stopped using it. But, the one thing I did notice is that the battery stats can be a little deceiving. If I left my phone off the charger and didn't use it for 10 hours and then started to play a game, it would look like I was getting good battery life as I would have about 60% battery left. Now if I played the game right after unplugging my phone, and then after the same 10 hours I'd be around 40%. Hopefully that makes sense.
One thing that I did do to overcome this was get an extended battery. It does add a little bulk, but now I can use my phone like I want and not have to worry about my phone dying on me at night. I can even forget to plug it in and still have battery the next day. For me I got the hyperion 4200 battery. The Zero Lemon seemed just to big for my tastes.
The other thing is also the ROM. At times I have found the same ROM but a different version exhibited different results. All ROM's offer something different so it is a give and take situation.
I hope this helped.

Yea my gps only turns on when my map turns on via tasker. I also dont have google now on.
Ya i understand what you mean on the percentages.
Ive seen people wiht great battery life, i wanted to try to acheive that without an extended bat. I was wondering if there was somehting that was obvious, or some radio battery drain fix. (I even tried only 3G, and still drains)
Thanks

It's a little hard to compare, but right now I'm on a 4.3 ROM and the battery life has been exceptional. Otherwise the next one that has been closest for me in terms of battery life has been Dandroid. Also, it's hard to judge a ROM after a day.
I guess I should have asked if you have tried or have any interest in a custom ROM.

I tried customs like AOKP, PA, CM etc before. I dindt notice a gain in bat life.
I do enjoy's stocks stability so I would like to find a solution with my stock phone. But doesnt see like theres one....

I've had a hard time getting really good battery life from the stock ROM. At best using greenify, I could prolong it a bit. If you are interested in a stock ROM with some tweaks, I always suggest S3Rx, or Dandroid if you want a slimmed down version without the bloat.
You can always try the power save mode as that does seem to help some, but you may experience some lag.

Ive frozen most of the bloat, greenified everything, plus I unclocked and under volted it, so any lag I would feel from power safe wont affect me since i believe power save throttles to 1350 ish .
