You guys probably all know about the Android OS battery bug that is present in ICS. But I recently flashed 4.0.4 stock leaked rom(it is for 4g but evilisto ported it for Nexus S) and I've used it for about 4 and a half hour. Then I went to battery tab to check my battery and saw this.

From this you can see that Android OS only used 3% of the battery. So I think that Android OS bug is fixed.

Awesome. Even with the so called bug I still get 48 hours with light use.
Wonder when the GSM 4.0.4. will be released?

Don't be too quick to praise it. Make sure there is a difference in battery life with the same usage and setup, before and after.
Dianne stated on google+ that the equation that shows awake time on the AOS service was slightly messed up (adding screen on time instead of subectracting it, basically). I don't know for sure, but this could change the battery use percentage for AOS making it seem like it's using more than it is. Not enough reliable info to come to conclusions here. But do just make sure it is getting better life with the SAME use. Sometimes it's easy to trust a number.

It never was a bug, Dianne Hackborn said, the "Android OS" is actually many things like kernel stuff and it doesn't affect battery life. They just changed what is logged under Android OS now. So don't expect a sudden "magical battery life". It was pure cosmetics. For source check Dianne Hackborns posts on Google+.
Btw, you get the best battery life, when you don't look at the meter all the time.

But didn't google pull the ics update because of battery related problems? fast batttery drain...if it was just cosmetics why would there be faster battery drain?
OK, I have done a new test to check of Android OS drains battery with no usage.
My Setup
Battery : 90%
Kernel : stock, 1000/200, ondemand, cfq
Android OS only drained 7% of the battery.
So you can see that Android OS thing is solved

They didn't state officially anything about a global update pull. A google employee only said, that they can limit the OTA install on some areas if they want. I got the OTA at the same time, as I reverted to GB for a week.
It's easy to see here, how some info gets misinterpreted and taken as a fact.
I flashed it on my 9023 (GSM), the android OS seems to drop a lot in battery use.
the major bug in 4.0.4 is the battery lift I think, so google should fix it this time.

They have disabled all OTA updates for i9020 and i9023 in many countries (it affects all updates, not just ICS). And there are plenty of reports of terrible battery life. It doesn't take much to figure out that one of the issues they are working on is fixing battery life in 4.0.4 which will most likely rollout to the GSM versions eventually.

It seems as though battery life is one of the most common topics among us vibrant owners. We are always looking to increase battery life, whether it be with a new rom, new kernels, or apps from the market. I wanted to start this thread for everyone to share their experiences, tricks of the trade, etc on getting the best battery life.
Post pictures, rom info, kernel info, app info, modem info, battery info etc! No pic, no proof!!!
This is the best I have been able to get with my phone with:
Bionix 1.3.1 - Stock kernel - KB1 modem - TW launcher - auto brightness off, set about 2 clicks from the left - battery calibration app used at 100% - Stock battery. Light / Light moderate usage, phone calls, texts, web searches. GPS on.

Well, this is great battery life you got there For me 24h is the most I can squeeze from my Vibrant with Project V/Bullet 1.42 kernel, auto brightness off, moderate usage. 16h with heavy usage... It's fully charged now so I don't have pics to show it
i used around 5% with in an hour with somewhat heavy usage this is cm7 nightly 71 bali with uv
srdjav - have you tried bali uv? I heard it works really well, especially with bi-winning, but I have heard great things about it on all different types of roms
gamikzone - impressive for cm7, I have read horror stories that the battery life on it wasn't all that great...but I guess with the kernel script and bali, it's way better!
@corpsetomb
Yes, I did tried Bali... But honestly, didn't see much difference in battery life. I have tried 4 different kernel on Project V and battery life was always 16-24h, depends of the usage. With extremely heavy usage 16h... So i decided to stay with Bullet 1.42.
But I didn't try Bi-Winning ROM yet... Maybe I will give it a try
But I had very bad experience with Super_DragonMODz 1.5 kernel... For a few hours everything was ok. But in one moment I picked up a phone after doing nothing for a half an hour and it was HOT! And I could smell "burning" inside Luckily when I took battery out and let the phone cool down, it was ok
Can we see pictures not words :/

haha what is this, a courtroom?
truly, none of this matters. one big factor in battery life is application use. in order to pinpoint someones battery usage, one would have to list, in detail, their application usage. which/how many apps poll for background data/how often? is the person using an autokiller/ram optimizer? which/how many apps stay open in the background, even when killed?
The bottom line is, battery life is ultimately determined by the user. there are only so many differences, in terms of battery, between these roms and kernels. none of them will give you a SIGNIFICANT difference. this is not the fault of the devs, they are not magicians.
This is why people do not get nice responses in rom/kernel threads when they ask "how is the battery life?". Then some clown who is a very light user will say "its great! i get 20hrs per cycle!!" and then you flash it expecting ground-shaking results...only you forgot that you have 317 apps on your phone (20 of which are constantly poll/checking for background data), and you use your phone/data like a whore who youll never see again. and unfortunately, there are horrible noobs out in there who, after doing this, will actually go back into the thread and say something like "DO NOT FLASH, MY BATTERY DOESNT EVEN LAST 8 HRS!!!!"
Theres only one true way to REALLY compare battery between ROMs/kernels (and it still isnt 100%trustworthy): download a ROM, try it out for a few days at moderate usage. Then flash the one you want to compare it to. Make sure you have the SAME exact setup as the ROM before (apps, brightness, GPS on/off, background data, etc.), and try to mimmick your usage with the other one. NOW you can effectively determine, relatively, which ROM may show better battery results for everybody. and then, when someone asks "does this have good battery?" you dont just say yes; you say "yes, i have seen noticeable improvement since coming from _______ rom, i about ___hrs more per full charge "
sorry for the rant

@TopShelf10
No worries, I welcome your input! I agree that a big factor in battery life is application use. You will see in the OP that I recommended people put in as much detail as possible along with their picture, such as what type of use, kernel, rom, etc. I would also like to hear and see comparisons between roms, that is part of what this thread is all about! To be able to compare different roms and see what helps based on usage.
Thank you for participating and your input!

You can manipulate the battery use stats pretty easily... at least on CM7. If I plug my phone in to charge for an hour, it doesn't reset my battery usage. Sometimes when I look at it it will say 24 hours+. Which I know is not at all accurate.

It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away.

Yup, I did after reading her post. All the battery stats are used for is to show which apps have been using your battery under Battery Usage.
That's a nice find. So all these while it was just a placebo :|

How many times have reps for companies given incorrect information? In the asus transformer prime forum there is a thread where an Asus customer service person said ics wasn't released for the prime, yet everyone is getting the ota for it.
I'm of the "I've owned more than 1 android phone and a battery calibration has never done anything" persuasion. It just never has. Users who get great battery life either have great signals or don't use their phone. Owning multiple chargers/batteries is the best way to ensure your phone has juice.

I agree. I don't think anyone states it actually "improves" battery life, it just helps ur phone be as accurate as possible so you don't has inconsistent battery levels. There's no way any fellow flash addicts have not experienced battery level inconsistencies after flashing roms. It happens to me all the time
Take at look at the steep drop in the graph. I'm pretty sure wiping battery stats is purely meant to correct that issue as opposed to actually increasing battery life

It is not a rep...it is a real engineer at Google Android, never saw the google+ link?
yep, quite believe it...never....ever wiped stats.
Fully charging the phone - firstly powered on, then off a few times, sorts the calibration.
And no...you don't damage the battery by fully charging powered on and off - they've made these batteries more intelligent than their gullible owners.
Seeing how a new firmware came out on the Nexus S, I want to see what kind of battery life everyone is getting on Android 4.1.1 Jellybean. And since everyone cares about battery drain one way or the other, we can use this thread to post tips on getting more battery life and/or try to figure out what's causing battery drain.
---
Anyway, PLEASE include these when showing your battery usage:
What ROM/kernel/Governor you're using
A combination of the three can determine why/how you're getting the battery life you're getting. Also, post thread link for the ROM/Kernel if you can.
SCREEN ON TIME
Probably the most important thing to know when determining battery life. Since the screen uses the most juice and generally the amount of time we'd be looking at our screen, the screen on time is very important to show. You can get this by going to Battery > Screen
YOUR GENERAL USAGE
How you used your phone is another important determining factor of how your battery was used. If you took pictures or listened to music, that would explain why you got such low battery life. More information the better.
IMAGES
Images help as it gives information which would be probably be too difficult to describe. The Battery section in the Setting section would help as would Battery monitoring apps
A simple template would be the following:
Code:
[B]*IMAGES[/B]
[B]ROM[/B] -
[B]KERNEL[/B] -
[B]GOVERNOR[/B] -
[B]GENERAL USAGE[/B]
blahblahblah
[B]CONCLUSION[/B]
blahblahblah
----
ADDITIONAL TIPS
- Show images of CPUSpy. May help see if your CPU is running out of whack or if, for some reason, is running on 1000MHz too much.
- BetterBatteryStats app screenshots. It gives a much better detail on what's waking up your phone, what apps are using it, and so on. You can buy it HERE. It's a very good app to monitor battery usage.
- More images the better. So we know what's going on with your phone.
PLEASE DONT
- Embed too many images to your post. It'll be too difficult to look at this thread with hundreds of images being embedded at the same time. Plus, people looking on mobile phones would probably struggle opening the page. If you have a lot of images, please just post the link and not an image
Anyway, thanks! Hopefully we can get amazing battery life on Jellybean!

ROM - Jellbean 4.1.1 OTA from here: http://goo.gl/AXr2d
KERNEL - Default/Stock kernel
GOVERNOR - Default/Stock
GENERAL USAGE
Usage was, in my opinion, light and didn't really do much. Most of the time, I was on 3G only to go on WiFi when in a Starbucks. I turned off my phone when watching The Dark Knight Rises and trying to save the most battery but that didn't really seem to help. I used the camera once in a while but didn't listen to any music.
CONCLUSION
So far, this battery seems kind of... bad. Especially with my usage (which I thought was light), I thought I could get more screen on time than just 2h 14m. I'm a tad disappointed and might go back to ICS just for the better battery life.
ROM: Unofficial CM10 by Lego
Lazy gov. Air kernel test 112.
The 2 hours of screen usage were from playing temple run, xda, and fb.

That's a good cycle IMO ^. Have you done a factory reset OP? Force of habit has me doing it anytime I do an update to avoid any issues. It also seems like you have a crappy signal at times. I haven't had a chance to actually judge battery life but mine seems to be on track to be about the same as it was as on ICS though.

It's weird because I'm using the same radio as on ICS and I seem to be getting worse signal on Jellybean? I might reflash a new JB ROM and try that instead.
I have a 2300mAh battery on stock JB i might upload some screenies later but i havent seen the battery life decrease it seems to be the same
Kind Regards

It's weird because I'm using the same radio as on ICS and I seem to be getting worse signal on Jellybean? I might reflash a new JB ROM and try that instead.

Yeah. I'm gonna probably go back my KF1 radio once I update my ROM tonight.
IMO I always do a preliminary test the battery when the phone switch to airplane mode in a night, if the drain only 1% then the ROM is quite good.

Right? I miss the GB battery life, could leave GPS and 3g on all night, not touch it, and lose 2% in 10 hours. With ICS I was grateful if I could get it down to 1.5%-2% in an hour. And Google Now is too awesome to turn stuff off for, so JB is even worse

My battery life is absolutely horrible. I think my battery is bad though. I've had it since I got the phone. When the nexus came out.

Its one of those pay to play situations. My job has places for me to safely charge my phone so the battery isn't too big a deal for me. Best bet is to carry a spare charger. It is after all a pocket computer. Sucks, but until battery tech catches up, there isn't much us or many other smartphone users can do.
I think the background sync drains battery when idle. With sync on during idle, the batt drops ~3-6%/hr. If sync is turned off, it becomes ~1%/hr. (using 3G)
Exactly what Google things syncing would cause such a drain? I have this type of usage but all I have is Gmail syncing and I only get a few emails a day. I have obviously noticed increased life disabling Gmail, but how could it be using so much if it is push?
I'm getting, at least, the double than before...stock, unrooted
I don't understand this.....
The only thing using CPU is Android system at 5-15%... why is this happening? The screen was off for at least 8 minutes

Since it just started up, and I'm guessing it is syncing like crazy. Calendar, instant upload if you have that in G+ or drop box chrome, contacts, drive, Gmail... Etc. Location is happening (maps, and latitude), checking for updates, weather. Check again in an hour and see if it has settled.

I havent noticed a problem with my battery. It's actually been pretty much the same. I go almost the entire day not charging it on normal use (almost 12 hrs). Heavy use with me is constantly playing games, I get maybe 3-5 hrs depending on screen brightness. It's pretty much the same as ICS for me
Hey there..
I'm thinking of getting this phone, but in every review, they say the battery life is pretty crappy... can somone please share their experiences or stats on this please?
Thanks!
Nobody has one yet....
FFS
even if it is horrible. These press units aren't being used "normally" or lightly. They are constantly being hammered to get every last thing about it to talk about.
We have kernels and roms to go on. My Galaxy Nexus last 35 hours on a single charge on a stock battery. While some people struggle to get even 10 hours on it.
Wait for the gsm arena battery test results and then compare the hours to other phones to see how it performes

These questions every device thread.the battery's on smart phones are crap.you want a phone that will last days...go retro and get a 3310
Get the phone anyway dude.I've got the x it has crap battery life..my one so had crap battery life..my nexus had crap battery life..my desire HD and desire had crap batter my n96 and n85 had crap battery life..
You get my point lol
The above is right we will have ROMs and kernels to make a deny but in the end lol all will need charging at the very least a day and a half

Exactly. my guess is also that it's because of the phone not being in the final software. Otherwise how could the same battery prove that worse compared to ICS lg Optimus? Jelly bean had a much better battery life in general too...
And IMO that is also the reason for the poor performance
Let's hope everything will be alright after the software update

The trend toward devices with internal batteries, ones that can’t be replaced, has come at the dismay of many power users who often need to switch to a fresh battery in the middle of the day. The Nexus 4 has a “non-removable” battery like most people expected, but it looks like it might be a lot easier to access than many might assume. You’re probably not going to make a battery swap in the middle of the day, but if you run into an issue with the battery, at least you know it won’t be impossible to replace.
Defective batteries and burn-out are a real concern with modern mobile device batteries, and while it may be fairly rare for something to go wrong, anyone with a smartphone who’s not willing to disassemble the entire device can tell you how frustrating it is to lose a phone to a bad battery. On November 2, a follower of Brian Klug, Senior Editor for Anandtech.com, sent him a tweet about battery replacement for the Nexus 4 on Twitter. Mr. Klug responded:
@aatifsumar there are two torx screws, then some plastic clips, it’s easy
Aatif pushed for a little more information and Mr. Klug responded with a great photo of the battery situation:
@aatifsumar two screws, boomhttp://twitpic.com/b9pbsj
The 2100mAh battery should be fairly capable of handling a day of moderate use, but for the fear of battery failure this is great news. Mr. Krug came through with another photo a little later giving a bigger picture of the situation.

Doesn't really solve anything anyone is talking about here. Being able to replace defective batteries is a separate issue from the phone's poor battery life.
Options:
1. If the info from me is usefull for you then push the "Thanks" button, cause all i want is to help you!
2. If not, read more!
3. Life is too short for other options!

Every review? No, engadget u mean? Most reviews had battery life as good to excellent for a smart phone. Dont panic and it is certainly not every review.

i think they plugged in charger at the red square
surely, it is impossible to reach 16 hour
Yes that's true. The nexus 4 consumes lot of battery life when the wifi is used.
I take all these battery complaints with a grain of salt. First, software was not final. I find it hard to believe it is going to be THAT much different than Optimus G.
Something else -- I had a friend who got a US GS III and had terrible battery life despite doing everything. Exchanged for a new one and battery life was double the first one. Do you think any of these "get it out first" reviewers considered this as a possibility? Heck, most of them didn't even mention that Google told them the OS code was not final.
It is worth noting that LG has had battery issues in the past. Was one of the reasons I didn't get an LG last year.
I'm finding the battery life to be pretty good. Over 36 hours and still going for light use. By light use, I mean I played a couple of videos, made a couple of calls, general internet surfing, lots of drop box syncing and more. Mostly all over Wifi. Also some wifi tethering for an hour or so. I also find that the battery charges quicker than normal too. Hope this helps
nexus 4 battery life
Hello Everyone
Battery is 35% before going to bed @ 11.35PM. Phone is dead at 8AM morning. 35% is not enough to stay idle for 8 hrs...

This I had my phone use 35% in 6 hours. That with usage.
So I was posting some info in another thread but I figured I would make my own thread for it. It seems like the power consumption at idle might be the cause for the "not as good as expected" battery life. For example my G3 will sit off the charger for 4 hours without being used and still be at 100%, the Turbo loses 6% in that time. The G3 has a 3000mAH Battery and I could easily get 24h of off the charger time on the G3. My question is what is killing the battery on the Turbo??? Its kinda hard to look over the battery stats when there is no root. Anyone have any input?
I think it's because of the wifi. I too have experienced crazy idle drain compared to my G2 and it's really making me regret getting this phone. It seems like they just slapped the kitkat ROM together and didn't really care to test it very well because Lollipop is coming out so soon.
It's definitely draining at idle more than usual or should be, I agree. I don't think it is WiFi related though, or at least not enough to be the main problem. I could be wrong of course. I have also not experience any WiFi or Bluetooth issues whatsoever and I use a Moto 360 all day, every day.
I am currently on my 4th charge cycle since acquiring the 64GB BN model. It's been powered on for 7h 32m and I'm sitting at 78% with 1hr 18m SoT. That's with heavy usage and taking quite a bit of pictures & video during this mornings product demo presentations at work.
Hardly anything for me personally to complain about. I'm sure they will optimize it. I'm almost certain than Android L 5.0 will make this phone a true beast.
Time will tell.
are you leaving gps or high accuracy location settings on?
I have the same issue as the OP. My G3 lost very little battery life when idling. I've attempted shutting down email accounts, turning off location and selectively removing apps in hopes of determining the cause of the drain...without success. This could be a deal breaker if we don't get some type of root exploit soon.
Well this sucks. I was going to get the Turbo but now I'm going to wait and see what happens with this drain issue. Maybe 5.0 will fix it.
I have been using the same settings that I did on my G3, Auto brightness, Location OFF and Auto Sync. Glad I'm not the only one noticing it too, I think its all in the build of Kit Kat they put on this phone, hopefully L comes out soon.

How about you start by posting screenshots of your battery stats from System...Battery
I don't have any issues whatsoever.
Well once I figure out how to do that I will post it, but in the mean time what phone were you coming from? A few people have agreed in this post that the battery life is worse @ idle then the G3 so its not just me.

Well G3 could be out of box, not trying to argue wanted to understand what your problem was. If you press the graph you'll see more details on what is using batteries (awake vs screen on, cell signal etc) and more in Android System if you go into that screen.
Overall what your getting .. 1-2% is not a big deal to me and beauty of the massive battery is you don't have to worry about but if really wanted to you could improve by turning off stuff you don't need or even automating it.
FWIW I'm coming from a GS3 with a tiny battery but even that phone lasted 5 days idling with the right setting for my use case (cell radio off / WiFi on). With Turbo just disabled some apps I didn't need and don't even think about it any more. I do have complaints about the Turbo but battery is definitely not one of them.
I'm interested in this as well. I bought my turbo yesterday evening and it had a pretty good charge (>80%) out of the box. I played with it for much of the evening and copied ~8gb of data to the phone via wifi. When I went to bed battery was at 60%, when I woke up it was 46%. I noticed that my third biggest battery use is command center, so I disabled auto-location in that app. I'm hoping to have better results on my first full charge.
Yeah I agree, but its literally the same settings I ran of my G3. I think I'm just gonna return it between the weak wifi and cell signal, and the camera it's just not worth it if the battery life isn't better then my G3
I've been posting in the other battery life thread... but to summarize, I'm going to be doing some thorough testing over the next 24/48 hours (currently ongoing).
I have already noticed significant improvements in my battery life. Has mentioned in the other thread. I'll be making a detailed post on Friday evening with my results.
I may also, from time to time post some of my progress, as I already have an understanding as to one of the issues involved with the so called "idle drain" everyone is referring to, and it is NOT WiFi.
Keep your eyes on that thread here.
Thanks, I'm pretty good with understanding wake locks, I just don't know where to start without root since most the stats in BB require it. I'm intrested to see what you come up with. I'm gonna wait till Saturday anyway to see if I still want to trade this in for the nexus.

Well you are limited with what you can do but I already gave you a start in my post, maybe you missed it. The only insight you will have without root (for tools like Better Battery Stats) is looking into all the info you can get out of Settings..Battery. There you can see wake locks vs screen on time and other stats like cell signal / wifi status etc. Then you can also dive into your biggest usage, for you it looks like it is Android System. They will list system services that are classified here. For example, you'll see the moto features are part of this. If you don't want to dig you can wait for Andromjb's updates
Overall I wouldn't base your decision to return the Turbo based on the battery -- base it on your other problems it sounds like you're having with wifi signal etc. That sounds like reason enough for a return. If you're ok with the larger size of the Nexus 6 then to me it's a no brainer to go with that instead of Droid Turbo since they are almost identical in terms of hardware.
For those that are getting battery drain, did you disable all of the verizon apps? There are some 20+ apps that are constantly running in the background and will drain your battery(even after i did a factory reset, these apps were sending data despite me never having opened them). Disable those, restart, then see if things change over the next cycle. I got 2d9hr31m and 4hr23 min of SOT(minimal usage) and was at 13%; this was on the first charge.
Could this drain be due to some of the sensors used for notifications. Doesn't the turbo have the feature where you stick your hand over it and it shows the notifications? If this is the case, wouldn't those sensors have to stay on?
Yeah I have 27 apps disabled and it really didn't make a difference for me like it has in the past, their must be something killing the battery on this 30m of screen time and I'm at 79% shouldn't be happening.

Thats actually really interesting. I haven't been experiencing anything like that. Perhaps try doing a factory reset then disabling them again. That's the only thing I did differently. Perhaps it's just a bad device? I'm already at 2hrs screen time, heavy downloading(off line apps), and have been on battery for 1d8hr- still at 45%. Is there anything in the battery stats? Wake locks perhaps?
