Something we keep forgetting Re: battery life - Samsung Galaxy Nexus

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

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.

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.

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.

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.

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).

Lot's of misinformation in this thread.
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.

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.

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.

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.

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.

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.

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

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.

Impressive battery life

I have been very impressed with the battery life I've been getting on my Nexus. the talk time has been much higher than any phone I've owned. Here are a few screenshots of my battery life. These two days are pretty much my normal day (lol yeah I talk a lot on the phone).
The first post will be the day that about 50% of the time I was on wifi.
The 2nd post will be screenshots from a day of being connected to hsdpa for the entire day (no wifi at all).
My setup: I use push email, facebook sync, auto brightness, gps on, bluetooth on.
Also, when the phone first came I charged it completely then ran the battery down until the phone shut off. I then charged it completely without removing it from the charger.
Below is the day where I was connected to wifi about half the time:
These screenshots show the next day where I used no wifi at all and was connected to hsdpa the entire time.
I have had mine for 2 days, and I have to say it seems to have pretty good life as well, compared to my Atrix and Note. After reading about all the gripes here,
I was expecting the worst. This battery will more than get me through everything I need to do with it in my day, but I suppose it all depends on what you do with the phone.

Coming from a G2x with a terrible 10 hour battery life, anything I get out of this is freaking fantastic compared to it! I Just wish the devs start getting out some UVed kernels so I can make it longer through the day! I consider myself a heavy user/texter (girlfriend ) and so I'd like to get through the whole day (~18 hours) without a charge I must say, I got to 16 hours yesterday and I was really pleased with that, never had a stock rom last so long without any tweeks!

mysterioustko: I think you're usage is a bit different to the average user. With all that talk time you're using the screen a lot less. It seems the screen sucks a lot of power, and if you're not using it often a full charge lasts 4 to 6 hours longer.

I typically average between 1-2 hours of screen time on an average day. But I talk A LOT each day lol. I'm impressed with the talk time because I've yet to see a phone besides this one that can go 6 hours of talk time in the real world when connected to hsdpa. Also, if you think about it, 1.5 hours of screen time is decent use. It's not a massive amount of use, but it's definitely not like it's getting no use. All in all I have been pleased with the battery life.
I don't know about you guys but im very disappointed in the battery life. With wifi turned on the entire day and no calls, just browsing and chatting on google talk, i got 3 hours 54 mins of screen on time before the phone reached 12% battery. I think thstss pretty horrendous. I was hoping for 7 hours or something of on screen time. My galaxy tab 10.1 has spoiled me i guess. Illl live with it because theres no other android phone im aware of that will give me more, but im kinda bummed about it.
My iPhone 4 has insane battery life... I cant imagine having less. Hopefully they sell larger batteries + backplates for the Galaxy Nexus?

Same here tbh. And the really frustrating part is, I only have 2G where I live so I was hoping to see really great battery life. Hasn't been the case so far though.
However having said that, just last night I flashed XXIK6 and while it's still very early to say for sure, it "appears" that battery life has significantly improved for me. Currently sitting on 91% after 3.5 hours with very, very light usage, IE: 15-20 mins screen on, 15 min phone calls, etc. Nothing to write home about sure, but way way better than before. It would normally be around 80% by now.
It's really sad when the very first thing you do after unlocking your phone is to go into setting to check your battery. Wish I could stop obsessing and enjoy this marvelous device without having to worry about it.
What did you guys do after getting the phone.
Did you charge it all the way to full before use, use and charge at the same time, or let it discharge all the way and then charge it to full?
Thanks.
I would have to say that the GN has the best battery life of any of my previous android phones. (G1, N1, Sensation) These things are very subjective though.

Yeah, and I don't want to lose the thinness of this gorgeous phone with an extended battery, but 4 hours of screen on time? Anyways, can you let us know how that radio works out, I'm not expecting much, but still curious. If it is noticeably better, I will try to unlock+root this phone. I'm just a little scared to brick this 700$ device.

2-3% per hour idle
I did a benchmark this afternoon for about 8 hours.
ITL41F rom, rooted + dcm kernel, otherwise stock. bluetooth, HSDPA, 1 gmail sync, and a few background sync that is very light.
idle the phone in home for 8 hours. the battery drops about 2-2.5% per hour consistently.
how long does it last with 'constant use' though?... from fully charged, to then having the screen on the whole time & doing web browsing, video watching, downloading, etc... (with data on, not wifi)

Lithium Ion cells do not get better in any way after a few charges.
In fact the capacity goes down a wee tiny little bit with each and every charge, so your first charge was the "best" one.
Stop playing around with the thing for 5 hours non stop and you will get decent runtime.
Best thing to do with a new device is to charge it up fully as soon as you can. Then run it down until you get the low battery warning. Then charge it back up.
Battery life will likely be pretty poor for the first week or so, then it will normalize.
Deep discharging (to 0%) is about the worst thing you can do to a LiIon battery, because it "hurts" it much more than several shallow discharges.
Also, like I said before, battery capacity won't in any way rise or "normalize" over the first week.
Battery life is poor the first days because you use your shiny new device all the time (i.e. more than later). It's like that for all of us.
My battery life sucked the first few days, It got better though. It really only seems to suck it down if it is hunting for a signal constantly.

You also need to try this manual battery calibration:
http://myhtcdesire.com/tutorials/how-to-improve-your-battery-life-calibration-tutorial
After I did this, saw the battery reading 99% and 98% more often rather than straight to 96% after charged.
Originally, it was suggested by HTC tech support. I did that once every six months or so ... And my battery level is now improved. Screenshots will follow in the next post.
Not bad?
Sync is off btw. And this includes using Maps 2%.
At least with my usage pattern, I am more or less satisfied.

You need to remember the only thing relating to battery life is not just the battery, it's software as well, hence calibration. After about a week or so your phone gets a "feel" for your battery and gets more battery stats, so it's more accurate with it's readings. That is a proven fact, you need to think about all things.

It is quite easy to gauge a Lithium Ion battery. 4.20 V = full. 3.60 V = empty. Your phone can read the battery precise to 0.001 V. The curve isn't linear, but it's well known what voltage relates to the exact capacity left in the battery.
There's really no room to "feel" anything there, just simple math.

I consistently get 15-18 hours of use out of mine with the extended battery.
But to the OP, if your screen is taking up 60% of your battery, it's always on, your battery is gonna die, it happens. Your battery doesn't get "better" with time. It seems that way because you aren't glued to the device 24/7.
Mine was god awful when I first got it but after a week or so it got much, much better.
I have the GSM version though.

Horrible battery life with their "extended" battery

I call it "extende" battery because it's 250maH more than the stock, big whoop.
I have maybe 10-15 calls per day. I unplug at 10am and by 4-5PM I am at 14% battery. There is NOTHING running. I even switched to CDMA only from LTE/CDMA and it didn't help much.
Any recommendations? I am about to return it. My HTC Thunderbolt which has the WORST battery life of ANY phone lasts me through the day and that's with Facebook and other notification apps.
Wait for 4.03 and see if that helps. Otherwise, turn down screen brightness, turn off LTE, and get better reception. Also, charge it every chance you get.
Sent from my Galaxy Nexus using xda premium
I can't fix any reception issues. This has horrible reception compared to my Thunderbolt as well which itself was bad with reception.
I have it on 3G only and the screen is already turned down.
I mean no disrespect but if the only option is to wait for a "patch" to fix this I probably should return it.
I paid out of contract price for this phone. $649.99 + 8.1% sales tax.
Don't get me wrong. This phone is blazing fast compared to my Thunderbolt but in the end I may just exchange it for an iPhone 4S which has sucky battery life but I can get through 2-3 days on a single charge.
If you even have to think about getting an iPhone, this phone isn't for you.
Seriously, something is probably wrong with your device. I get no reception issues. Sounds like that is the brunt if your issues.
Sent from my Galaxy Nexus using XDA App
I would say return the 2100mAh battery at least but don't return the phone. LTE is a huge battery hog as is and with the size of this screen it isn't helping either. I'm anxiously awaiting either Mugen or Seidio to make a decent extended battery for it. There is a generic 'made in China' 3800mAh battery currently circulating around eBay pretty cheap, although I haven't tried it out myself yet.
How long have you been using the extended battery? You have to give it at least a week before making any decisions.
I've had the phone since Monday/Tuesday
You should first compare with the standard battery with the same usage pattern. If the standard battery gives you more time then there's a problem with your extended battery. If the standard battery gives you less time, then the extended battery is okay but you should look at your rom settings instead.

If you're using the phone lightly and losing 85% in 6 hours, then there is a hardware problem. Don't buy into the hype that an OS update is going to fix the problem, it probably won't. I have great battery life on my GN using 4.0.2. I think a lot of people have a hardware defected phone, and are in for a surprise when the OS update launches and doesn't fix the battery issues. The Galaxy S already got 4.0.3, and users are still reporting massive battery drain.
Carry a few batteries or a charger and enjoy.

I have found that the battery life I get with my extended battery is above and beyond anything I would have expected. Use WiFi if it is available for you at work or at home because it's typically faster (unless you have 4G signal and slow wifi) and uses much less power than typical cell radios.

Lol totally a reasonable way to keep your phone functional. Hey, just sew another pocket on your jeans just to hold cellphone batteries, no biggie.
I think battery life varies wildly depending on individual circumstances.
My area has stellar LTE reception, I keep the screen at 30% brightness, and I do light web browsing, RSS viewing, and podcast listening.
With the extended battery, I get anywhere from 9-12 hours before hitting 5% battery. Battery usage typically shows ~50% screen and ~20% Android OS.
Granted, battery life dips significantly when gaming or watching Netflix, which I always do at 100% brightness.

What is your screen on time? How many apps do you have installed? Are you running stock? Has the phone actually died?
Just because it says its that low doesn't even mean it's that low. Could be an error in reporting. I don't pay much attention to the percent... I go by when my phone actually dies.

GSM nexus battery life WAY better than Verizon Nexus

My two Brothers just picked up the unlocked GSM Nexus off the Play/Market store last week. One has it running on pre-paid T-Mobile, the other on Straight Talk ATT, and their battery life is ****ing unbelievably better than what three of us get on the Verizon Nexus, and we are not using 4G/LTE at all.
Both my Brothers use their phone at work, no Wifi just the 3G signal, and they both text me this week telling me battery life %. Right now after 4+ hours unplugged they both around 85%-90%, not using it except sending several texts and reading websites. And after a work day unplugged for like 10 hours they both have like 70%-75% left.
Now myself, my Wife and buddy have the Verizon Nexus, my Wife barely uses her phone at all, and at lunch time will be at like 70% battery left, and after getting home still unplugged for 10+ hours she's at like 45%. Where my Brothers with same use would be at 70%.
My buddy has the same as my Wife's usage, no WiFi wither, not using phone much and his phone is at like 40% after 12 hours or so. Both of them have 4G/LTE off and GPS off, and no sync on.
I use my phone a lot for work sales calls, and I am in the red by like 4:00pm, I get maybe 7 - 9 hours of use on a busy workday.
My Brother on the GSM T-Mobile, said after 23 hours his phone was at 45% battery life, and that was him using it quite a bit, dozens and dozens of texts, lots of websurfing, tons of e-mails. Our Verizon Nexus would never get that kind of battery life.
It is known. What really matters though is screen on time.

I agree screen time is crucial. But my Wife uses her Verizon Nexus very little at work and by time she comes home is at like 45% battery after about 12 hours or so. My Brother on GSM Nexus after 12 hours and using it a bit more would be at 70% battery.
That is a HUGE difference in battery life with very similar use.

That is a HUGE difference in battery life with very similar use.

do they work in the same building?
if your wife works in a place with not as good of a signal, i expect her battery to drain faster as the phone is trying to get more signal.
I installed AOKP 5 on her phone last night. Her battery seems much better. Unplugged for 7 hours at 80% battery now. That is a major upgrade. But again she barely uses her phone at all during work, pretty much just sits there. Where my Brother with same use today is at 90%.
I am running CM9, unplugged for 6 hours at 35% battery, but I use my phone a lot during work. Have 2.5 hours screen time. Tons of texts...lots emails...several phone calls....web surfing.

With GSM you can expect around 3 hours screen time and tons of standby time.
The standby time is great, but the screen time is somewhat mediocre to me.
Some days my battery just gets ate and others (like today) I'm having good battery. Usually I'm finding that apps are open in the background even after I hit back to "close" them. So if I keep up on the "Recents" menu and swipe it all away, I see an improvement.
I'm waiting for the MIUI styled "X" that closes ALL recent apps in one strike. Every little bit helps. An older version of Gummy (x.8) I had insane battery life. From 8am-3pm I would still have like 75%. I'm running LiquidSmooth right now and at 3pm I am at 60%. This was with 40 emails and 2 20min calls. No texting today
But LiquidSmooth has more options and is much faster then Gummy, so IMO the small battery difference is a good trade off. Later Gummy versions seems to consume more battery while lacking in the features.
AOKP never ran well for me in either the performance or battery department. Seemed to be laggy AND battery lousy. However I haven't played with it in a few weeks.
I too keep 4G disabled but I also have WiFi on all day (I never turn it off). I also use "Bluetooth On Call" which enables my bluetooth while on a call, so I can use a wireless headset. It automatically disables bluetooth, but I'm sure it consumes more battery then a normal call.
I only have 40minutes of screen ON time too. Mostly quick checks of emails. A few turns of WordFued and DrawSomething. I do work in a dungeon with little/no signal, which I suspect eats it up.

It is known. What really matters though is screen on time.

But it depends what you do in that screen time. If you do a lot of gaming and browsing with 3 hours it's great. If you just swipe through the home screen and send a couple text message with 6 hours of screen time, not so great.
A cool test would be to turn on airplane mode and play a movie. I'd be interested to see if it has something to do with programming vs hardware.
Then the same test with 3G.
Both really need to be setup similarly, same wallpaper, apps, etc, to really get a good measure of comparison
This isn't a news flash. Its been pretty well known.

Well, yes and no. Gaming does use more cpu and such than just flipping through your home screens so I see where your coming from and agree to an extent.. But also consider that display is almost always the biggest battery consumer in battery stats, regardless of what you are using it for.
If you switch the 4G off then it will be a different story.

If you really want to compare the battery on all those phones, at the end of the day have your wife, your buddy, your brothers, etc...send you a screen shot of their battery stats. There are so many reasons why your battery life can change, and unless you are following someone all day then you really won't know the full picture.
And yes I usually say screen on time is a better "quick" comparison of battery life. Someone who has a display timeout of 1 min compared to someone with 5 min will have significantly different battery results, even with similar usage.
LTE is a *****.

CDMA radio technology is a bit worse on battery than GSM, I'm betting that's where most of the difference comes from (LTE excluded obviously). With my screen on constantly, I've gone over 5.5 hours of screen on time before on my VZW GNex with about 50% 3G/50% WIFI usage. Again though, that was almost constant screen on from 100% to 0% battery. I've also watched the entirety of LOTR: Return of the King Extended Cut (4:20 minute run time) with my phone while also having 2 or so hours of standby on one charge, but I was in airplane mode for the majority of the movie watching. The screen is absolutely the worst battery killer by leaps and bounds and that will hold true no matter the variant.

True, it always is the biggest battery consumer as anything you do on the phone requires the screen to be on. But it also depends on what kind of users we are. If you use your phone mainly for calling and texting and emails, then 4+ hours of screen time with a total of 16 hours should be good and doable. But if you do a lot of gaming, browsing web, tasks that are heavy then 3hours+ on screen time with a total of 10-12 hours on the chart is pretty good I think.
I agree with a previous poster, screen on time is all that matters. That's why I got an ugly humpbacked Trexcell 3800 battery. Now I get 5 1/2 hours of screen on time on my Verizon GNex. Great when compared to my old time of about 2 hours.

None of us on the Verizon Nexus have 4G on. We all leave LTE off.
So why is the GSM version getting substantially better battery life ? Seems to be at least a 25% difference, if not 1/3rd better battery life on the GSM Nexus.

See my post above. CDMA radios are slightly worse on battery than GSM radios.
Like I said, I've seen 5.5 hours of screen on before once and 4+ many many times. I highly doubt the difference in battery between my VZW Nexus and a GSM Nexus under constant use from 100% charge would be more than +/-5% in either direction so the difference is somewhere in the standby times of the two devices ie. GSM vs. CDMA radio.

Battery...hmm not bad

So I 've been wanting to really test how long my battery could go with minimal use.
This included...
about 45 minutes of 3G tethering
and about 13 hours on 3G. 4G was disabled the whole entire time
As you can see it was idle a lot, but I almost got 2 full days on stock battery. So no complaints.
Part of me feels like if it was not for that 3G tethering maybe I could have got 4 more hours+
Not bad indeed.
Would rather use my phone and have to charge when I get home then leave it in my pocket all day.
Also your wifi was toggled on the whole time... that would have saved some battery.

my gnexus can only last 1hr and 50mins of screen time and i have to charge it ~2 or ~3 times per day.

That sounds pretty dire....are you running at full brightness with Wifi and bluetooth and the GPS on (happens e.g. if you enable GPS for apps and then open Facebook) and no screen timeout while running the camera?
I've had an hour of screen time, and about 9 hours of screen off; I've not had it on to charge at all today, and I'm at 60% battery.
If you go into settings/battery, what else is keeping your phone awake? In other threads, people suggest installing 'Better Battery Stats' (nb, cheap, not free) and posting screen shots of the kernel/partial wakelocks. I can't interpret them myself, but others can...

How is the signal strength where you spend most of your time?
When I'm at home, it's crap, and I'm about in the same boat as you.
You can get the better battery stats for free if you can locate the guys thread here on xda. But I recommend at least donating to him for such a useful app.

The only complaint I have with this phone is the massive difference between hspa and lte versions in battery life. Other than the razr maxx no late phone has acceptable battery life including the nexus. To get 5-6.5 hours screen time on my nexus versus friends 2.5-3 on an lte version is just crummy. I know some people just have extra batteries but that short of usable battery life is just too much of a hassle for me when I'm out and about. I would be forced to get a huge ugly seidio battery if I needed to move to Verizon. Even with 4g disabled the Verizon/sprint versions don't get the screen time I get with my hspa nexus. I really hope lte radios get more efficient and battery tech gets better. Removable or not, all phones can be made as sleek with a huge battery if manufacturers wanted. The maxx is proof of that.

I am giving my machine a hard time every day. Usually it ****s up after something like 4 hours. That is much better than the old machine I had. However, it is not good enough cause I work for 8 hours. So after the midday break in the canteen there is no more angry birds for me. I think of getting a second machine, one for the morning and one for the afternoon.
Yay, another super 1337 battery thread.
Check out my super 1337 battery savings with a stock battery!!!

I'm lucky to break 2 hours screen time on my GSM phone before I have to recharge. How the hell you guys managing such spectacular battery life?

what's your signal strength during that time? At work I get horrible reception, and leave work probably around their percent. Weekend I could away without charging

Lol, how's this for on screen time on a stock battery? I just managed to get the screens before I had to charge it up, It's the longest I've gotten with my ROM and kernel combo. Last screen shows it's the ~1800 mAh battery, the third line down reads 35/1750 mAh.
*Edit* Hold the phone, 1400 mAh is stock, right? My 'stock' battery is 1750mAh... How does that work?

Is everyone else getting strange battery drops? When the battery is at 19%, it drops directly to 15%, without going through 18,17,16. Is this happening to you or is my battery screwed up? It's been doing it for weeks now so I don't think it's about lack of battery training
This is with a genuine 2000mah extended battery, minimal use over a long weekend. This is also with emails, facebook etc all polling at 30 min intervals, wifi on but not always connected and screen on auto brightness. I had also conditioned the battery by fully charging and discharging about 5 times when the battery was new.
