[Samsung Galaxy Nexus] EP2008:
I've become obsessed with the poor battery life on my new Galaxy Nexus and I've been pouring over forums, videos and blogs to find out why it's so bad.

I keep hearing about people getting 8 hours, 11 hours, 14 hours before their phone dies, but this is not actual use time, it's idle time (I.e "I left the phone off the charger overnight and..."). WHY does the manufacturer rate this phone as having a 15 day standby life... FIFTEEN DAYS!!!!

Something is terribly wrong here. If I can't use the browser for more than an hour without the battery getting critical, then what's the point of a "super phone "? It seems useless. I don't even want to install games on this device, because I know I'll get frustrated by it chewing through the battery as I play.

I purchased this phone with a high priority on the HD video recording capabilities, but will I actually be able to film stuff while out and have enough juice in case I need to make a call? Something tells me I won't.

Maybe I'm just expecting too much or maybe manufacturers should stop making these phones so "super" and focus on the fact that these are portable devices which need to last at least the day. God forbid you went for a hike and had an emergency, only to find your phone dead after eight hours!

Rant over :rolleyes:
[Samsung Galaxy Nexus] El Daddy:
My battery is currently at 60% after 13 hours and and 1:35 screen time.

I have absolutely no complaints about the battery. In fact I would say its the best out of any phone I've owned.

I feel you bud! The first 10-12% drops super fast then it seems to get a little better?

did u check out the 2100 mAh extended battery, it's working wonders for me
[Samsung Galaxy Nexus] KWKSLVR:
That's because when you pull your phone off the charger and it says it's @100%, it's lying. It's somewhere in between 95-99%. The first 10% is spent figuring out where you're really at.
[Samsung Galaxy Nexus] @rbiter:
I think op said it best himself. Maybe you're just expecting too much. Battery life is freaking awesome for a phone with a 4.65 inch oled screen. Reminds me of my trusty nokia e71 back in the day.

[Samsung Galaxy Nexus] @rbiter:
If your battery is properly calibrated, the first 5% is iffy. Just figured out how to properly calibrate less than two weeks ago and it doesn't include any software, like batterycalibration or resetting battery stats in cwm.

[Samsung Galaxy Nexus] EP2008:
You can kindly replace "hike" with "family outing", "work", "movies", night club", "sporting event", "errands", etc... having a spare battery or charger (or a second communication device!) on you all the time should NOT be the solution to poor design (either hardware or software or both).
[Samsung Galaxy Nexus] Valynor:
Lot's of misinformation in this thread. :eek:

A new Lithium-Ion battery (LiCoO2) is always 100% fully charged at 4.20 V (+- 0.05 V). This maximum voltage lowers with age and use of the cell. Both voltage and battery age can be precisely measured by your phone and translated into the battery % display. It's not a linear graph but it's not really rocket science either. :)

There is no calibration of LiIon cells, it's neither necessary nor possible, they work at 100% efficiency right from the start.
[Samsung Galaxy Nexus] martonikaj:
You going on some intense 12 hour night club runs?
[Samsung Galaxy Nexus] EP2008:
i'm at 24% after 12.5h, 1:45h screen time (inverted theme browser and some brief facebook/twitter time...). This, to me is not acceptable. If I was using google maps + gps, how long until the battery died? 30 minutes? Less?? I'm not watching video, making calls, downloading torrents, using the camera or anything else that would cause this kind of drain, but it seems to be "normal" for a lot of users on this and other forums.
[Samsung Galaxy Nexus] okplaya:
Have to agree with most and say battery life is by far the best compared to all other Android phones I've owned. As for standby time, this is tested without a sim card, apps, etc. So 15 days sounds reasonable without touching it and without the phone doing anything in the background.
[Samsung Galaxy Nexus] gogol:
I disagree.

The battery life of this phone is fantastic, more than what I expected. It is better than the Nexus S that I have.

I am using extended battery 2000mAh for GSM version.

Battery drain during night is about 1%-2% for about 8 hours. No kidding, I was surprised with that this morning. Probably because the new 4.0.2. Before, it was half percent an hour.

My current record for battery life was 61 hours with 4 hours screen on time. See the attached screenshot.

Again, this is based on my usage pattern.
[Samsung Galaxy Nexus] Bisazz:
Battery life is amazing to me too, My average usage a day at work is 8-9 hours music, 45-60mins 3g web browsing, ~1h 40 mins screen on time.

On my Desire HD (Yea I know, hopeless battery life) the battery would die around 7-8 hours in with that usage. On my Galaxy Nexus I get home with 50% left.

One thing I found that helped battery life out a TON, is swiping facebook off the recent apps menu when you're done with it. Also have a similar high drain problem with joystiq/engadget apps.

Running AKOP17 with francokernel12 for anyone wondering.
[Samsung Galaxy Nexus] beardedspoooon:
I think you need to specify CDMA or GSM. It seems pretty common for GSM to get around 4 hours screen time before the battery goes. CDMA: 2.5 hours or so with moderate-heavy use.

I really hope someone on Verizon will post that they get 4 hours screen on time (no wifi) and what they did to get it.
[Samsung Galaxy Nexus] player911:
Battery is good here too. Android OS is the eater. 4.0.3 and a good kernel fixes that.

The phone is capable of good battery but the new OS is still buggy.

LTE EX Galaxy Nexus - AOSP KANG

Asus Transformer - 3.2.1 OC/UV
[Samsung Galaxy Nexus] Aridon:
Franco Kernel with a core powered down on screen offm 325 / 1200 clock.

Exiting / logging off google talk

Entering camera and force closing it one time after each reboot

LTE off

Nets me 1% drain per hour on 3g with nothing going on. That is excellent battery life. Loging out of Gtalk netted me approximately 2% an hour and the camera close trick netted me a crap ton. Prior to that I was getting almost 8% per hour loss doing nothing.
[Samsung Galaxy Nexus] Thracks:
That means there really is a problem with battery life, doesn't it? If people have to open and close cameras and sign out of a dormant, built-in service to triple their idle battery life, something is wrong.

Imagine how many people don't know about these tricks, and are watching their battery tank in 12-15 hours?

Think about it.
[Samsung Galaxy Nexus] EP2008:
This is unacceptable. If someone wanted to just buy a phone and use it,they shouldn't have to go through hoops and even disable features that are built in.

I'm on stock 4.0.1 ICS using the built in apps that came with the phone. It seems silly that I can't use the phone or the battery will die before lunch. What's the point of all these features?

Look at the iPhone battery life. It can multitask just as well as this phone yet gets almost ten hours of on screen time. This is a design flaw which shouldn't be excused.

I love android and this phone, but is it too much to ask for an answer to these battery problems?
[Samsung Galaxy Nexus] Bigal77:
Iphone screen is also one inch smaller and no 4g, that alone doubles the life of the android

Also no widgets on iphone
[Samsung Galaxy Nexus] El Daddy:
10 hours of screen on time with the iPhone huh? I'd love to see proof of that.

To be honest, it seems like you are expecting too much. Until there is a breakthrough in battery tech we won't see battery life like Nokia candy bar dumb phones from 10 years ago.

Its just something you have to accept. Myself and many others are completely content with our phones. My advice is to stop worrying about battery life and enjoy it for what it is. Get a second battery or an extended battery if you just can't make it through the day.

With that said, I can say with complete certainty that creating a thread and and complaining about it will not improve battery life.
[Samsung Galaxy Nexus] mike216:

Sorry, it's 11 hours browser time with the IPhone 4s on wifi, which is what I'm using, since I don't have a standard data plan.

http://www.anandtech.com/show/4971/apple-iphone-4s-review-att-verizon/15

I'm not trying to ***** and moan because I want to complain, I'm bringing up a legitimate concern. There is a problem with many Galaxy Nexus devices and battery drain.

Getting a second battery is a poor suggestion for someone who uses their phone off and on throughout the day... I'm a typical user and if having to swap batteries at 3pm sounds reasonable, then I guess that's why manufacturers have become lazy with this.

I would rather have a device that's 2mm thicker and twice the battery capacity. It can be done, so why don't they do it? nevermind the high resolution display, quad-core CPUs, NFC chips and LTE. Let batteries catch up to the technology first.

In any case, my OP was about how Samsung claims a 15 day standby time with is phone and clearly, that's not a "real world" expectation.

I'll be performing more experiments with my GN to see if this problem is just user error... Maybe it is...

That is what people are forgetting. If they wanted a polished device thats been tested over and over, and has less bugs due to said testing, then this phone was not a good fit for them.
[Samsung Galaxy Nexus] martonikaj:
It's not going to change your battery life drastically. its only a 13% bump in mAh.
[Samsung Galaxy Nexus] Aridon:
I agree. You are preaching to the wrong person.

Average user isn't going to come here, I simply shared some things that helped my battery life. No more no less.

There is a reason people buy and like Iphones. They work out of the box for the most part. Although Siri is causing them a lot of battery drain as well on the 4s. So no one is immune.
[Samsung Galaxy Nexus] djkinetic:
If battery life is really a big issue for you then I suggest you stick with iOS/iPhone... Android has never had as great battery life as iPhones...that said I can usually get 18hrs of average use before i need to put my phone on a charger...this is with the HSPA model the CDMA model sucks up more juice...but thats how it's always been GSM phones have always gotten better battery life then CDMA...pretty much you can either buy another battery, live with the battery life on the nex or use an iPhone...it may not be acceptable to you however battery life has been more then acceptable for me...my advice is to upgrade to 4.0.3 roms since u say you're on 4.0.2, i personally use AOKP with Lean Kernel..i've also used Gummy Nex with Lean Kernel, which provides great battery life...note if u do flash another rom..give it a couple cycles before you judge battery life...newly flashed roms usually give you lower battery life readings but get better after a few cycles.
[Samsung Galaxy Nexus] xXJay_RXx:
I never been able to get great battery life. I mean I was streaming Slacker Radio last night for about 6-7 hours at work over 3G and my extended battery was done in about 7-8 hours. Idk maybe I'm expecting too much from my phone :/
[Samsung Galaxy Nexus] gogol:
iPhone is cute and small with it's tiny screen.

It doesn't fully multitasking, you should know this.

It doesn't have widget either.

That's why it's battery life is quite good.

If you see my post previously, I got very good battery life. And note that I don't do anything special, except using extended battery. I don't root, I don't unlock, I am using stock rom.

Probably Android is too difficult for you, in this case iPhone will suit you better :)

[Samsung Galaxy Nexus] yondercomesthetrain:
Franco Kernel #12 is your best bet. I know its a bunch of "hoops you need to jump through" to get good battery life, but seriously, why get a Galaxy Nexus if you didn't have the intent on tinkering with it?
[Samsung Galaxy Nexus] mike216:
I know we can't calibrate the battery itself but I know the system can be recalibrated
[Samsung Galaxy Nexus] EP2008:
More excuses.

iOS multitasks just as good, if not better than Android for most things. Having owned at least a half dozen android devices and using them 12+ hours a day, I can assure you that iOS multitasks as good.

No widgets on ios? I've turned my widgets off on my phone and still get crappy battery life. In fact, I can turn off all the features I use and still get poor battery life!

As an experiment, I turned off EVERYTHING on my phone - airplane mode ON, sync off, location services off, sounds off, notifications on individual apps off, NFC off, no wifi, no Bluetooth. I lost 4% per hour doing this. Is that acceptable to you?

Smaller screen on the iPhone, sure, but it's getting more than double the battery life not just 20%.

This is an android problem. Anyone will tell you this. The fact remains that a phone should be able to last more than a few hours of actual use NOT idle time.

Stock or custom roms? The Android OS process is still high even with everything turned off and this seems to be a common problem with ICS (see the huge thread on this subject).
[Samsung Galaxy Nexus] NewMossie:
Be realistic

I agree this phone doesn't have the best battery. My old HTC Desire lasted longer with a smaller battery.

But then again, think about what's important to you in a phone. You probably shouldn't have gotten an Android if battery life is critical for you. I got the GN because I value flexibility and customization over battery life.

There is no perfect phone out there, every phone has different strengths and weakness. Just know what's important for you and go with the best match. Complaining incessantly isn't going to change a phone's design.
[Samsung Galaxy Nexus] RogerPodacter:
i'm on stock 4.0.1 and i lose about 3% overnight during 8 hours. and this is with wifi on, 2 gmail accounts syncing, calendar, google+. the standby time on this phone is just insane for me.
[Samsung Galaxy Nexus] rman18:
Batt life

If I shut off location services and sign out of G+ I get 3% loss after 9 hours of sleep time..

I'll lose 12% if I keep them on.

I can get about 2 hours of screen time on 3g/4g... 3 on wifi.

Not horrible, not great... Its about the same as I got with my Droid Incredible. I've learned to deal with it, and I can honestly say that there has only been one time where the battery nearly failed me as I was out in 2 years.

[Samsung Galaxy Nexus] EP2008:
3% loss in total or per hour?

My concern is more the screen time, not idle time. I want to use to this phone, not keep it on standby - I could do that with a dumb phone and get two weeks off the charger! LOL
[Samsung Galaxy Nexus] aohus:
most folks here seem to be interested in idle standby time for some reason.

everyone only posts their idle time. that being said, i only get about 2.5 hours of on-screen time with 4G enabled all day (LTE).
[Samsung Galaxy Nexus] RogerPodacter:
3-4% loss in total. it loses about 1% every 2-3 hours. so at night it's at 95% and i wake up 8 hours later at 91%, with all my syncs going etc.

its the same thing at work. when i'm not using the phone, the battery meter just stays dead flat during idle. sure it drains when i use the screen on. but it idles like a champ better than any phone i've had before!

interestingly, regarding screen-on time. i started reading an ebook lately. and yesterday i had 1 hours of screen time and was still at 87% battery. this thing is a superb book reader so far. then i got to 2 hours of screen time at 75%. so while web browsing might drain fast, the screen IS efficient at reading. that equates to around 8 hours of actual screen reading time.
[Samsung Galaxy Nexus] adrynalyne:
If you want 15 day standby:

Take out your sim. Remain 100% stock, and never once turn the screen on. You will get your 15 days.

Edit: I think your carrier is wrong. Its rated for 12 days. Nowhere does it say 15.
[Samsung Galaxy Nexus] EP2008:
Now I'm intrigued. How the heck are you getting those numbers? I'd be a happy camper to get close to your battery life.

Do you have any settings turned off, like location? What other apps do you have syncing? Weather apps, Facebook, twitter?
[Samsung Galaxy Nexus] @rbiter:
I easily get 4 hours screen time. Waiting to bust 6 hours with extended battery. Dang Roger, why don't you just put a black screen on and tell us you can get 12 hours screen time. Lol.

[Samsung Galaxy Nexus] j.bruha:
I know that a lot of people are reading into these discussions as potential troll bait for an iPhone vs Android discussion, but I want to weigh in to help put that to bed. I've been perhaps the biggest Android fanboy since the Nexus One, owning the Nexus S and now the Galaxy Nexus, with various devices in between. My house is riddled with random Android paraphernalia and I sing its praises to all who ask (as well as many who don't).

All that said, the Galaxy Nexus (LTE) is the first Android phone that has made me think long and hard about getting an iPhone, (to much shock and awe of friends and coworkers). It is not for lack of features on Android, the exact opposite in fact. I, like a lot of people in this thread, just want to be able to use my phone the way I want and not have to donate a portion of my attention to making sure my phone will last a full day. As it is now, with little to NO use on my phone in a given day, I have to constantly monitor what I do to ensure that it doesn't die before the end of the day. I've experimented with stock, various, ROM's, various kernels, and various configurations of my devices setup. No matter what, battery life has remained abysmal at best. Battery life seems to have gotten worse with each new phone that to which I've upgraded, and while I understand the more recent devices have added features like LTE to add to that drain, it's still so, so much worse than what I've experienced on an iPhone.

I'm patiently waiting for the next update Google is working on (4.03/4.1/4.x?) that is supposed to correct the Android OS drain bug. I'm not expecting comparable battery life to the iPhone. I just want to be able to use my phone moderately without it completely dying by the end of the day. If it takes a decent stock ROM to do that, so be it. I just want to set it, forget it, and charge my phone every night like I used to with my Nexus S.

So if nothing else, have an open mind when people are comparing battery life to the iPhone (especially HSPA+ users that don't see the battery life LTE users are complaining about). No one's trying to troll anybody else.
[Samsung Galaxy Nexus] EP2008:
I can understand not turning on the screen, but taking out the sim? That's not standby anymore, since the phone can't be used as intended...

A little FYI for the Android fans... Apple gives battery run times and explains the REAL WORLD tests they performed to get those values. None of this airplane mode, turn this off and that off, they just run the test like a user would use their device - play some movies, listen to some songs, brows the net, makes some calls, etc.

Here are the IPhone 4S ratings, as given by apple (and verified via several review sites):

Talk time: Up to 8 hours on 3G, up to 14 hours on 2G (GSM)

Standby time: Up to 200 hours

Internet use: Up to 6 hours on 3G, up to 9 hours on Wi-Fi

Video playback: Up to 10 hours

Audio playback: Up to 40 hours

And here is their no-bull testing conditions:

http://www.apple.com/iphone/battery.html
[Samsung Galaxy Nexus] adrynalyne:
If its on standby, its not to be used at all. Standby time ratings are for 100% perfect situations, perfect signal, and does not account for any type of syncing, screen time, or usage.
[Samsung Galaxy Nexus] EP2008:

1 google calendar

location

google+
