REALISTIC battery life ??? - Samsung Galaxy Nexus

I was just curious what you guys and gals were actually seeing from your batteries?
I have an LTE GNex that is rooted with APex ROM and Franco Kernel.
Everything i read is about all this fantastic battery life... im just not experiencing that. I did purchase francos app to keep the kernel updated and to support him. I am also running Antutu Battery Saver on Level 3. My phone will lose 10% an hour just replying to a few texts and sitting idle in my pocket. If i watch a few youtube videos or listen to some music itll drain quickly. Has any one experienced similar?
CPUspy shows that the phone spends most of its time in deep sleep... what is going on?

From the looks of your screenshot, it shows you have low signal. The phone could be dying faster trying to hold onto extra signal if you spend most of your time where the screenshot was taken

first thing i would do is get rid of that battery saver u dont need it and make sure ur on a current radio , mine and a few others battery posts are on frankos kernel thread page 747 . the first 20% OF my battery from full charge always drops fast than after that slows down . hope helps u

wow, thanks for the quick replies!
I thought maybe it could be struggling with a signal.. this house is the dang bermuda triangle of cell service... however with the same 2 bars of LTE im still getting decent speeds....
I am on the 4.0.2 radios only other ones i saw were the leaked 4.0.4 and from what i have read about them, they are iffy...
Thanks so much for posting a page number!!!!!!! i was getting worn out reading and finding nothing on his kernel page!!
I will ditch the battery app and see what happens with that...
I am also losing my OC... is this the fault of the kernel and the rom fighting to own the permission to OC ??? ill set it and check it a while later and ill be back to 1000mhz...
thanks again for the replies
much appreciated,
j

LTE will usually give you good speeds even with one bar. The problem is when the radio senses a weak signal the phone pushed more power to the radio in an attempt to catch and hold onto that signal

oohhhh that makes more sense then. so it could still be this dang house! lol
i will be in BFE west texas next week without a hint of LTE... ill put phone on CDMA and i bet my battery goes a full day then...
the Kernel Page only had 245 pages ... i didnt find the battery stuff... ill keep after it and see what i can come us with...
thanks again...

i have a gsm gnex and my house is also a very low signal area, 2 bars or 100 dBm is very good and the phone is constantly switching from edge to 3g but even with all this i still get excellent battery life. try switching radios like other said, certain radio are better at switching from 2g to 3g or LTE. im also using apex with the apex kernal. its the best one in terms of battery life, very simple and minimal but works great. there wasnt anything causing wakelocks.
did you check if you have any apps or process interrupting the phones sleep? 10% an hour seems more than just a radio problem but i could be wrong since LTE does use more power. try downloading better battery stats, its free, and will tell you what process or apps are waking your phone.

I would turn off lte and sync when not needed ...try stock rom and see how the battery life is...use it for few days then install a custom rom if needed

OK, So i downloaded better battery stats and found that i had a process that was really doing a number on me it was... "mobi.mgeek.TunnyBrowser" I did some research on it and found that it had to do with dolphin browser. I removed the browser, the bookmarks to SD, and the faster load... the process then went away and the battery percentages appeared to be more normal.
However im still losing battery really quickly. I unchecked some synced things that i dont use, browser, calendar, photos, music and wallet... hopefully this all helps.
I was sad to lose dolphin but i found Chrome instead... very very nice!!
I will watch the processes... i did not see anything that was waking the phone..
Thanks again!

Horrible Battery Life When I'm Not Even Using My Phone??

Well everynight before I go to sleep I charge my phone fully and unplug it before I sleep
Usually I would only lose about 1 % or 2% overnight
But this week I would lose over 60% over night! Its outragous!
I looked at what was killing my battery and "Cell Standby" and "Phone idle" were both over 45 - 49% !!
Anyway I can fix this problem??
Thank You

There may be some random issue with your nearby cell tower, causing the signal to be weaker than normal (particularly 3G). This might cause your phone to be constantly looking for the tower, and killing the battery. I've noticed this to happen at my house, although the difference in battery usage is not as severe as what you describe.
If you haven't changed anything on your phone, I would just leave it be for a few days and see if improve on their own.

As redpoint73 said .its probably because of weak 3g signals ,set your phone to "2g only"
overnight and see if it make any different. i dont think different radio will help ,different kernel might do .

Turn off data completely and see if it still drains. If that stops the drain, change your radio.
Remember you must be radio s-off to do that. Root with gfree (you'll need the cm 6.1.0 kernel or stock).

There's no good answer to that. What radio is the "best" varies by geographic location. The best way to find out is by trial and error, although the newest radio tends to be the best place to start. Some people seem to be having some decent luck with the latest AUS radio. But like I said, its all just trial and error. I remember on my last phone (Touch Pro 2) people sometimes reported better battery life and reception by flashing older radios.
EDIT: I just noticed this thread: http://forum.xda-developers.com/showthread.php?t=990860
Some people claim EXCESSIVE battery drain using the newest AUS radio, while others do not. So it still goes back to my statement that trial and error is your best bet.

Im running on GingerVillain 1.5 with stock radio as well
I don't use the profiles on setcpu, they're confusing and annoying. I don't even keep it overclocked much, only when I use my phone alot. When my phone is idle I set it back down to 806, sometimes even 700.
Wifi is on all the time when I am at home
GPS = on for me (at home)
screen brightness is like 40%
I keep 4g on all the time as well
At night, I keep my phone unplugged at 100% than the next day its at 99%
Ill use it for maybe 20 minutes and its at 90%. After about an hour and a half it goes to like 75% than ill put it back on standby for maybe an hour than its at like 73%
To sum it up, if its in standby, its fine
If im using it from 100% to 0% it lasts a good 3-5 hours depending on if im streaming vids, listening to music, and browsing the internet.
Im testing the waters with different settings and roms as of now..
GingerVillain is my favorite so far.

Have a few questions :)

I might be buying one of these bad boys. And i have a couple of questions.
1. How is the GPS on this device? Does it lock on pretty quick? Also im talking about stock, not with any tweaks or anything added.
2. How about signal? Does it get good signal? Like if T-Mobiles map says it has excelent 3g coverage will i get that inside a building?
3. Hows the camera? I heard it was the best and looking at pics taken from it it looks pretty spectacular. But nothing speaks more then users opinions
EDIT: missed one 4. Under moderate use, texting throughout the day, hows the battery life? Also hows it with heavy use?
Thanks guys for your time!
Battery sucks with any use, GPS locks on pretty quick(15 sec or so)
The camera is great, by far the best I have seen on a cell phone and just as good as our point and shoot.
I always have good signal on T-Mobile

Thanks! I figured battery life wouldnt be too good considering its using the Super Amoled + display. I was planning on buying an extended battery anyhow. About how long does it last? Like from what time do you unplug it till it reaches zero?
I personally believe the battery to be fairly standard, but definitely not horrible. I keep my display brightness at probably 75% and it lasts me ALL day and usually needs charging at around 10. Definitely manageable, and this is heavy to moderate use; ALOT of texting, maybe 30 minutes of gameplay, live wallpaper, wifi on for about half the time, AND this is on AOKP ICS ROM so battery life would be considerably better on a stock ROM or even one that allows under-clocking. Hope this helped!
Honestly I think battery on life on stock is great well at least for me....with modetate to heavy use...that including alot of Web browsing, text, calls....it last me a good solid 12 hrs. best battery life I've had on any smart phone I've owned. This phone is just amazing in every aspect the only phone I think that is better than this is the HTC one X. obviously using GPS and stuff is going to drain it more so it depends on how u use it..

The GPS on this phone has never failed me.
As far as signal. If its good near you then you will be fine. I get 4G in my apartment and do over 20 mbps dl speeds inside.
I think the Camera is better than my wifes Sensation..
I am a moderate to heavy user. I mean Texts, Calls maybe a game lots of web with usually over 2.5 hours of screen on time and on stock I was doing 13 or 14 hours..
Rooted, under clocked, and undervolted I have went over 20 hours.

Thats impressive! 20 hours! Woah! thanks for that i'll def consider making a profile in setCPU or tasker or even make my own apk which will under clock and undervolt when i want it
I have a second question though, what is the difference between the Samsung Galaxy S II (T-Mobile SGH-T989) and the Samsung Galaxy S II X (SGH-T989D)

ics and battery life

At first my girlfriend had her Nexus S updated to ics and immediately we noticed a huge difference in how long her battery lasted and she is the furthest thing from a heavy user.
So when I heard that ics ws being released for our phone my first thought was i hope that what she experienced won't be what i do as we have a better phone right?
Well I am sad to say on a stock but rooted rom I experience the same lack of battery life as her.
Now I am no beginner to Android and have changed all sorts of settings available and nothing syncs on its own and when I unplug my phone from charging in the morning I will need to plug my phone in at night before bed as my phone will be completely dead.
I have to say I am very disappointed in the battery life of thr the stock rom and hope some good kernels make it out to help.

Have you tried to find out which app/process is draining your battery? Better Battery Stats can help you identify what is using up your battery.
I had a big keep awake problem when i first installed stock ICS on my T989D. I did a full wipe of the phone and formatted my internal SD card (after backing things up of course), reinstall the same stock ICS and everything works great now. Battery life is about the same as before (stock GB w/ Synergy kernel), which is about 30 hours with moderate use.
Try CM 9. I get almost 2 days of battery life.

Though I am now on AOKP, I had great battery life on stock ICS as well. But, everything is subjective. How many email accounts are being synced? Do you have Facebook / Twitter / G+ updating every hour? Do you have news feeds continuously updating as well?
I have to agree with the poster above. Get Better Battery Stats and find the culprit draining your battery and work from there.
biggest thing draining the battery is the screen.
you can literally watch the battery usage drop 10-15% in a period of 10 to 15 minutes which is absurd when its set to low.

Wait for kernel development. Its underway as we speak. It will make a significant difference.
Some battery saving tips:
- use juicedefender and set it to aggressive mode.
- use romtoolbox or other programs to underclock cpu frequency.
- also try using telus stock ics. Very good battery life.

I have a brand new T989D (I'm new to Android, former iPhone user) and got the ICS upgrade the day I got it (9 days ago). Battery life is terrible, I'm lucky if I get 10 hours of moderate usage. The phone also tends to run very, very hot. Sometimes apps freeze and all I can do is either wait or, in some cases, remove the battery to reboot.
I'm open to any tips that will get this fixed! I haven't rooted yet (no time). I think I will try those wipe tools and reflash the stock ICS ROM.
First post btw - glad to have joined XDA!
Rooting takes 5 seconds. Follow the sticky. Use odin.

Stock, not rooted, my battery life is great. Something is using your battery up, and flashing some exotic kernel isn't going to change that. The stock kernel works fine. You'll want to find the root of the problem. Keep a real-time (or 1-5s interval anyway) eye on the phone's current (mA) usage, and when it's high for no apparent reason, you'll know that whatever is sucking your battery is doing it right then. That should help you characterize the problem. I've noticed when my WCDMA/GSM radio signal sucks, so does the battery life, so I either turn off the radio or switch to GSM only when I'm in that area. If your display is what's eating your battery, well a kernel can't stop that. Turn the brightness down, leave it on auto-brightness, or just deal with it if you need the display on all the time. But if tweaking and modding makes you happy, by all means...

I have the same complaint. The "screen" battery usage is just unacceptable, especially compared to GB. My phone has been draining from a full charge for ~4.5 hours and my screen usage is 70% and battery is down to 65% with hardly 10 minutes of screen-on time.
I use an app called autostarts and you basically enable/disable apps that start running when certain events happen (phone startup, wifi being turned on, incoming call/sms/mms, other apps turning on, etc.). Just make sure you do your homework so you dont disable something critical. Hopefully this app works on ICS. You'll be surprised what different events make certain apps turn on automaticly. Screen, data/wifi, gps and bluetooth are the biggest battery drainers. No matter what Rom you are on if you don't keep control of those items your battery will drain fast. Keep ur screen on auto, let it go off @ 15 seconds ( you have to be pretty used to your phone for that setting not to annoy you), turn OFF your data or wifi when not in use. With bluetooth and gps...well u know that when you use them your battery is gonna drain faster than normal...just keep that in mind. Its all pretty much common sense.
I'm not going to tell you how much battery time I get cuz its nonsense. There are times my phone lasts till the next day and others Im charging it by sundown. Then again Im still on Juggs n Darkside kernel and Im gonna wait a bit still b4 I make the switch. Also don't go by what other people say on battery life cuz if you might not get the same results on that ROM. Everyone of our devices is unique and acts different. Everyone user uses their phone different. You can't define "light, moderate, heavy" use so don't go by that either.

After upgrading to ICS stock unrooted battery life sucked (5-6hrs). I did the whole remove battery, factory reset and still sucked.
Broke down rooted (still stock), downloaded batterycalibration from play, followed the instructions. Easily get over 24hrs before having to charge again. and when I say easily, I mean I still have over 25% left.

Bingo. Vastly different battery life between ROM's is generally BS. Every once in a great while one of these threads has merit but typically someone saying ROM X had "Killer" battery life is clueless and drinking the koolaid. Then a placebo effect takes place. And definitely someones "Heavy" use is subjective. If someone says they get a day out of an android phone they are not heavy users by my definition. It doesn't happen with heavy use. Perhaps the Razr Maxx or another phone with a very large battery but I've had 5 Android phones. If I get past noon it's because I am not using my phone that much and forget about a full day. It's never happened in the 4 years I've used google OS phones. Never.

Yes exactly, I hate when people post screenshots of their phone getting 24+ hours, I'm there thinking "well obviously they don't use their phone alot". There is no way in hell i could get 24 hours no matter what rom/kernal I use. Im just happy when my phone can make it till I get home at night

SOLVED: ICS Upgrade Myth Dispelled - Factory Reset Does Not Fix Battery Drain

EDIT: Please read this entire thread, there's some good info. Every phone and every situation is different, however it turns out my battery drain was the result of my phone not hitting "Deep Sleep". The culprit was my SD card, if you're experiencing battery drain after upgrading to ICS try removing your SD card and restarting your phone, use the app CPU SPY to verify your phone is now hitting "Deep Sleep". Again please read on, amidst some trolls there is more detailed information.
SIDENOTE: This being my first thread I have to say on the whole I really like this community!
I never thought I'd be that guy saying don't upgrade to ICS, because the OS is so slick and fun. However the glitch with the battery drain nullifies it's value. My brand new phone, less than two months old will die before the end of the day without me making a single phone call. I'm talking maybe an 1 to 1.5 hours of use texting, checking mail, surfing, and my battery now runs dead before I even get home from work. If you go into Settings > Battery it will show you the break down of what's using what. At the top should be your display, it takes a lot of power for to run the ultra bright display and this is what I saw before the ICS update. After the update these are the numbers:
Android OS: 58%
Screen: 18%
Cell Standby: 10%
Phone Idle: 7%
Android System: 2%
The OS is taking 58% of the battery?!? This is crazy!The buzz going around the net is if you do a factory reset it will fix the issue, well it does, but only for a very short time.
I went through the pain and formatted my SD card, then did a factory reset on my phone lost everything, well I backed it up, but still was a long process. After all that I loaded up my apps, and everything looked great. If you I went into the battery break down Screen was back at the top and the Android OS was several rungs below. I was SO happy! It was worth it after all.... THEN
Imagine my chagrin I woke up this morning to a full charge. Didn't make one phone call, just checked a couple emails, and being only a HOUR into my day my battery is at 76%!! I look back at the battery break down, and there's Android OS sitting at the top, draining double the battery juice as the screen display. I mean this almost makes ICS useless, what good is this great cell phone if you have to be tethered to a power cord. WTF!! Point being, don't bother resetting your phone, it DOES NOT permanently help. If you haven't upgraded to ICS don't, we're all just screwed until they come out with a fix, and you see how long it took them just to get ICS.
I don't know what happened between last night and today, but my hope is some dev person will read this and it will help them pinpoint the issue.

Nope, the only thing I backed up was pics, music, and video, and I combed through those folders to make sure there were no sys files.
It sounds more like your battery is going bad. You can go to Sprint store and they will test your battery for you.

It looks like your phone may never be going into deep sleep. Get CPUSpy from Google Play and see what is going on.

Having a bad battery would not make Android OS use the majority of his power though. I have had this problem myself in the past and never did figure out exactly what stopped it. Running Blue Kuban now and my battery life, though never great, is reasonable. FYI, I also run Juice Defender which makes a substantial difference for me.
Running pretty much stock ICS FF18, just have agat safe recovery/kernal installed. Yesterday I left Wimax on all day and when I went to charge it last night it had about 28% left. I made several phone calls, many texts/whatsapp messages, reading emails and using twiitter/fb a couple of times.
The battery life on this is not the greatest, for example, I forgot to turn off wifi when I left my house the other day, well my battery dropped about 30% in just a few hours. I now find that just leaving Wimax on all day is actually better and pretty much on par with just having 3G on, I prefer wifi at home but if I forget to turn it off it kills my battery.
I was so used to Blazers 4.1 battery life, the battery lasted forever and I could leave wifi, bluetooth etc on all day. Just hoping for the ROMs to start incorporating the recently released source so that we can get better battery life on these great ROMS.
This is all known information. That's why you use custom roms that have much better battery life.

I had same issue here with custom rom FF18 touched by SGS3. Went back to EL29, FF18 is glitchy and slower anyway.
Confirmed, factory reset battery drain exists.
OP, why don't you put up a screenshot of your battery graph? The expanded one, not the one that lists the percentages.
There are a number of reasons why this could be happening. One of my biggest drainers on CM9 was Google login service, turned out the "keep this device backed up with Google" in the backup and reset settings was completely preventing my phone from going to sleep. This is but one example.

You guys need to quit crying wolf and figure out what is really draining your battery. Maybe your google drive is syncing, or you have facebook running, or email is pulling too often, ICS does not kill battery rogue apps and wrong settings do.
Try this https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats (search xda for other versions)
and this https://play.google.com/store/apps/details?id=nextapp.systempanel&hl=en
Figure out whats waking up your phone and running when its not supposed to be and until you have data STFU

seconded, attached is the battery stats for an average day for me on ff18 based goodness.... these "problems" are all able to be resolved rather easily with very little effort... this is not a paid tech support forum and no one is going to spoon feed you when solutions have been posted countless times in countless hysterical threads like this

My phone is not rooted and this is the battery life I'm getting after the OTA with light use. With regular use I get at least 25-30 hours.

Just curious, what's your display time. From the looks of it, doesn't seem like much. But still, that's pretty impressive nonetheless.

I'm a super n00b, if you or someone could link me to the best ICS ROM the cool kids are using I can figure out how to install it.
-----
However bottom line, before ICS upgrade my battery life was great and my Android OS was not 50% of my battery power. I'm not rooted or have any custom anything, after the ICS upgrade my battery drains rapidly. I'm willing to do what it takes to get it fixed, however I do fully put the blame on ICS, I'm using stock everything, the battery is good, something in that update is screwing my battery.
All I was trying to do was give developers, a little insight that the factory reset temporarily fixed the issue, for 3-4 hours before bed I monitored it and everything was good. So hopefully this will help turn the light bulb on in someone else's head.

ICS works really well for some, but for others it renders the phone completely useless. I'm one that it won't work for as well. The battery life is **** and 4g connectivity is non existent. As a result, I'm back to EL29/GB until a patch is made.
I spent 4 days after teh OTA was released trying to find fixes, trying to make it work, using different kernals and modems, but had no success. I posted about it many times and more or less was told that I was doing it wrong.
On that not, good luck mate. Here's to hoping for a patch from samsung soon. :good:

I have a thread stickied in general called "welcome to he et4g" that might be a good place for you to start, from there you'll figure out what you need to search for to learn more... there is no best rom its a matter of opinion, so read the dev threads and see what looks good to you... bottom line without seeing more information from you I would guess you have something running in the background preventing deep sleep, as mentioned earlier... also are you leaving wifi, Bluetooth, etc on? That'll kill your battery quick... do you live in an area with poor sprint signal? Constantly searching for service will also drain you battery. What do you have to set up to sync? And how often? There are easy ways to prolong battery life on ff18 and the vast majority of people complaining about battery life have not taken positive steps to learn more and resolve their own issues... it can be done, good luck

Battery Drain

Is there an app or way that conserves the battery power. The phone is still completely stock but it received a firmware update through Tmobile and ever since then the battery gets drained by 4 pm (after all apps are x-ed out and phone is just in standby) the batter drops to around 30 percent... what can I do? I don't think it needs a new battery since its only a few months old... suggestions?

I dont know how much you use your phone and weather or not you watch movies or download files with Wi-Fi alot but it could seriously drain your battery if you leave things like Wi-Fi, Bluetooth, NFC, Brightness Up, or use live wallpapers.
If not, I would recommend checking your battery against someone elses because I've had a phone before that had a bad battery that could explode and caused me to have battery issues. Make sure your battery isnt swollen at all and if it is make sure you take it out and dont put it back in and go to a Battery+ store nearby and I'm sure they got one for your phone (they come with warranty).
Well my wife and I have the same phone and it does it to both. I don't have signal in my job since they have a Verizon antenna and it blocks our t mobile signal so I don't use it during the day which means the phone is just on stand by for the first eight hours. I make sure I turn off wifi, blue tooth, GPS etc and close all apps....but by the time I get out of work it's at 30-40% power.... both phones were bought this April so was hoping it wasn't/isn't a hardware issue and have to replace the batteries....

This is where the world of rooting and tweaking your android becomes extremely attractive.
There are ROMs that last 1 day + ( that's 24h+ hours of battery)
Only need two things....
1. Patience - to sit, read and closely follow instructions
2. Guts - to take a dive and risk ruining your phone. (Which doesn't happen if you have number 1)

thanks for the reply. Yeah I've been thinking about doing such things, but am a complete noob. Is there a link to a tutorial (from start to finish) on rooting/flashing custom rom in here? All I see is one or two step threads or discussions on different roms?

1. juice defender is a start.
The rest all needs rooting really.
2. Build.prop tweaks
3. UV with a custom kernel
4. Lowest screen brightness (doesn't require root)
5. Restrict yourself to 2G networks either using AOKP settings or a build.prop tweak
There are others but this is how I achieve great battery times mostly.

Why not try and find out what is using your battery up first? Try GSAM from the play store, its free for one, easy to use, it will show you what is draining your battery, there are a few paid ones as well, but try the free first , HERE is the direct link to GSAM.
or QR code, just scan it with phone.

That is a very weird situation and try a app that shows the apps using battery. Even check the stock android battery section in settings and see whats getting used. Your brightness should be first since it can really eat your battery if its turned up. I dont think its defective since both your phones are having the same problem but both my parents have the 4.0.4 firmware installed on their T989's without a problem and get decent battery power. I however am using a custom rom with kernel. Did you use the same battery for each phone? or each phone has the same problem with their own devices and their own batteries when getting updated to 4.0.4? If you used your battery on her's I'm assuming the problem may be the battery and you just got unlucky with a defective one.
P.S. I'm assuming 4.0.4 because thats the latest update to ICS for the T989 on T-Mobile.
The battery manager that comes with the phone identifies the display, but I've set it to lowest setting and have a dark background. And yeah both phones have their respective batteries which makes me think it's a software issue.. We just upgraded to the 2.3.6 ( I guess t-mobile is a but behind lol). But I going to try the juice defender tomorrow... It's just while I root the phone and get a custom ROM... (doing my homework before doing anything since it'll be first time)

Those apps wont really help, it basically does what you can do manually, turning off settings or putting them at low usage. Rooting is the way to go, its rather simple, once you do it, you will have wished you done it sooner. Trust me, I was in the same boat, I had just got my phone last december, the wife and I were in Vegas and my battery was horrible, I was taking lots of pictures and video, but my battery was dying. I had no way to charge it til we got back to the hotel, next day was same thing, horrible battery, this was all before ICS even was around for this device. When I got back home, I rooted my phone, to date, I have gotten a best 44 hours out of the phone. I ROM hop so I try out the variety, there is how to's and videos here and youtube, you will kick youself on how easy it truly is to root and flash. GSAM will show you in more detail what is using your battery the most, good luck with whatever you choose to do. There are many people here who can help you along the way, thats what this site is for.
Juice Defender will help a ton with you're screen being off for extended periods of time. Normally without it, I lose 30% at work without touching it. Today, I have lost 6%. The margin won't always be like that but it's a sizeable difference. Also, I have an app monitor application you can use to track rogue apps. There is also this app called Autostarts where you can disable an app from opening and it's really useful for apps that you don't need running in the background. Turning off auto sync will help as well IF you are okay with not getting every email in 5 minutes.
