I'm off to get my Galaxy Nexus tomorrow, but after hearing some of the poor battery reviews, I want to make sure I get off to a good start.
I heard something about there being a significant difference in how Samsung batteries perform if they are first "primed". How exactly do you prime a Samsung/Galaxy Nexus battery to ensure it gets the maximum life out of it?
Any non-battery tips are also welcome, as I want to make sure to make the best use of my Galaxy Nexus (coming from a Nexus One).
I would let the battery die, then leave it on the charger for 6-8 hours during the first charge.

I'd do what he said but charge it to full first... and drain it to dead from full twice.

just received my phone, put in my sim and battery and hooked it up to the charger without turning it on.
will take it off the charger when the battery is full and start using it (it is already charging for about an hour now and still not full)
Great, thanks to all three of you. I'm hoping for better than my Nexus One, but I can't really imagine it being worse than my old HTC Touch Pro. (4 hours on standby, hell yeah!)
Btw. It's not advisable to let the batteries run dead completely, this can lead to damage, poor performance and reduced charging capabilities.
I'm not an expert, but if you google mobile phone battery best practices something should pop up.

If I'm correct though, the phone turns off before it hits 0% so that the battery is not damaged. But I'm no expert either.
I'll stock up on some battery articles and see what I can find, thanks again.
Do what it says in the manual?

Good guide; it's nice to see some numbers actually attached to that.
The manual, however, just says to "charge the phone to full capacity" first, but nothing afterward.
Irrespective, the phone is now charging and I'm ready for some Ice Cream Sandwich goodness. Thanks guys! ^^
You can also get one of the battery apps from the android market. I got Battery Doctor and like it. It provides more precise control, and has a charge tab which lets you see exactly how much charge is there and lets you know when fully charged.
I get about 16 hours with moderate use (forums, phone calls, updating calender, etc). I get about 20+ hours when I am only checking facebook and forums.
Regards,
I havn't calibrated once and I received my phone a week ago.
It was also a display model, I think, as the box looked pretty warn out and there was no set up screen upon first getting it.
Will this present an issue or can I calibrate now and have the same benefits I would get if I calibrated a brand new one?
Hey all, I'm looking for some advice regarding the battery on my Verizon Nexus and I wanted to see if anyone else was having troubles too. It seems as though my battery is discharging very very quickly to the point of where I'll pull it off the charger at 100% and within 10 minutes I'm down to 90% with little to no usage. Again, this is the stock battery on the Verizon Nexus. Thanks all!

take a look into this discussion http://forum.xda-developers.com/showthread.php?t=1387243
Stock ROM/Kernel? Try changing, see if the drainage issue changes. Even reflashing an updated stock image may help.
It looks like the problem is the screen using up the battery. Its using 66% of the battery right now and I'm down to 88% battery after about 25 minutes with brightness on 10%.

That's standard behavior for most phones. It damages the battery's long-term life to keep it charged to 100% for extended periods of time. It actually trickles down to 90% while on the charger after reaching 100%, but doesn't actually tell you so, because people would get confused if their phone sat at 90% while on the charger.
Lots of laptops do the same thing. E.g. my thinkpad never charges to more than 94-96%. Standard behavior to maintain the battery. The computer is just up front about it, and the phones do it more sneakily.

Hmmm, that sort of makes sense but I've never seen this behavior on anything else including the many many Android phones I've used in the past...its annoying. I'm thinking about picking up the extended battery but I'm not sure.

I had the same problem the first two days of owning the Nexus. I would go to work at 6am and the battery would be drained by 12. I did a few things that seemed to help.
1. Disabled 4G LTE
- My area is spotty when it comes to 4G, so the phone constantly searched for it.
2. Lowered Screen Resolution to 10%
3. Used a dark background.
- The screen will use less power if the background is dark (black is best)
Doing those three things made my phone last from 6am to 6:30pm, which is a noticeable improvement. This was done using the stock battery. I did order an Extended battery, but I have not received it yet.
Lol this happens with basically all mobile devices.

not with my friend's 4s.
My battery also drains very fast. I'm at 48% with screen using 33% and android os using 31%. My screen on time is only 58 minutes but android os has kept the device awake for over 2.5 hours
I have a Galaxy Nexus, I had a Droid Incredible 2 before that, and a Droid Incredible 1 before that, and *all* of them have exhibited this behavior.
My nexus was in and out of 4g tonight and I'm at 35% with 9 hours on battery. Used a lot of Google music in the car. FWIW I'm using set CPU . That's probably helping a bit.

Just about. I usually get 7hrs.

Thats a drastic drop! Id say about normal as well. Did you have a lot of apps that were re downloading from the time you first activated it. After a few days to a week when your done looking at your phone every 5 secs you'll start to see battery improvement haha.
Tonight will be my 3rd time charging it. WIll it get a lot better tomorrow?
ProTip: Put the phone down every once in a while and enjoy life.
That's normal if ur 4g on

It can take 4-5 charge cycles for the battery to really get worked in.
Also, check out the juice defender plus app. Doubled my battery life.

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.

If you are using your phone a laptop replacement and are surfing the web constantly, expect it to die like a laptop.

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.
I wish Google fixes the high Android OS Keep awake time!

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.
60% screen time gawt damn! Did you talk to anyone that day?

Google need to run classes on how to read the battery consumption pages. 61% screen means that the screen used 61% of the total battery used, not that the screen was on 61% of the time.

I have had the phone for 5 days and with fairly light usage, I am still not getting good battery life. I turn off all data and wifi when not using it and screen on time is below 2 hours.

It doesn't get better...get used to it until its fixed in an update , along with the other big issues.
Sent from my Galaxy Nexus using xda premium
By about the 3rd day it seemed better. But it's also difficult to gauge because the first few days you're bound to toy with it constantly.
Until there is an empirical way to gauge usage, like an amp meter attached to the phone - it's all perception imo.

In the top left you have three things running in the background, im assuming constantly. Uninstall them, especially the battery percentage since you can look that up easily on your phone

Do yourself a favor and try aokp milestone 1 from rootzwiki , and also download lean kernel 1.1.1 on xda. Use interactiveX governor for kernel. This is the exact setup I am using now, and have been for a few days and have been getting insane battery life. Hope everything works for you.

You really have no idea what you're talking about. First of all, it will get better, I won't bother explaining the science behind it considering you can do your own research, but it will, also, it can't be "fixed." Just like they can't make it an 8 mega pixel camera in an OTA. You can get it much better by doing custom roms and thigns of that nature.

It got better when I turned off vzw backup and google +.
Best I got is 16 hours bone stock just an extended battery. Worst I got was 4 hours(screen was on the whole time) watched 2 movies before I plugged in. I average around 12 hours from 100% to 20%.

First off, it's hard to tell by your screenshot how good or bad your battery life is. You're burning approximately 10%/hr, but maybe you had your screen on or were surfing the internet for a portion of that time. Anything that involves data transfer will kill your battery faster.
I got my Galaxy Nexus on Wednesday, and I've had great battery from the start. I calibrated it by letting the phone's initial charge die down to zero, and then charged it all the way up to 100%, and then used the Battery Calibration tool. I drain between 2-3% hour with light use, but can obviously drain much more depending on what I'm using the phone for.
That being said, for those on this board who think an OS upgrade is going to fix the problem, I highly doubt it. I have a reasonably poor cell signal (averages around -95 dbm), but still get solid battery life. Given that we were all issued phones with the same software, if you're experiencing incredibly bad battery life, I'm going to point my finger at the hardware. It just doesn't make sense that some of us with 4.0.2 get great battery life, and others do not. You probably have either a bad battery or a bad phone. Now, I'll probably get called out for saying this, but watch all the posts that follow when the update releases, when people still have poor battery life.
This is my 3rd Android phone (Incredible, Charge, GN), and every one of these phones has had poor battery life. On average, if I'm playing around with the screen on, I'm draining upwards of 10%/hr, if not more. But if you properly calibrate the battery - which is VERY important - you should easily be able to get a full day's charge out of your phone.
There is a post on XDA about the 13 steps to proper battery calibration. Once I followed it on my last phone, my battery life went up at least 50%. You have to let the battery drain to 100%, then bump charge a number of times, then use the battery calibrator.

Try running without JuiceDefender. Constantly toggling data on and off (or wifi on and off) actually hurts battery in almost all cases.

Your results may vary, but when I used Juice Defender or Green Power on my Droid Charge, I nearly doubled the battery life. I haven't put it on my GN yet because my battery life is much better than what I had with the Charge.
No using JD or anything like that. Just the the phone do its thing. I don't even open the multitask button unless I want to switch between apps.

Gotta be a software issue with the battery.
Just this past weekend in Wash DC. Very strong 4 G market.
I had it fully charged off charger. After 7 hours without touching the phone even with google plus sign out, the battery went from 100% to 54%. It's like the phone was active a lot without me even touching it. No SMS/mms either. No emails either.
Know. I did same thing and put it on airplane mode with it 100% charged. After 7 hours on airplane mode it was at 98%.
So it's gotta be an operating system issue.
I tried it on wifi instead of 4G mode. And battery drainage was down to 72% after no use overnight.
Hi.
I've got a question about Galaxy Naxus, earlier I've got HTC sensation and I had to charge it every night thats why I bought iPhone 4 cuz it has a lot of better battery, but now I know I hate iOS and want back to android, I want to buy a Nexus device (Nexus 4 or Galaxy Nexus). And now my question is how long it takes to discharge battery in GNexus ?
My use is about:
-50 sms daily
-5-10min calls
-1h web on 3G
-2-3h web on wifi
Has Galaxy Nexus enought good battery life to hold out 2 days of my use ?
Battery life depends on so many variables, it is nearly impossible to say what sort of battery life someone may get.
That said, 2 days of ~5hours of screen on time. I can say with almost 100% certainty that you won't be able to get that out of any Android device without some massive battery, swapping batteries, or charging at some point.
If by 2 days u mean phone out of charger on day one at 6am to charger again on day 2 9pm..it is possible if u tune up the usage as u have mentioned.. But if u keep turning on the screen every now and then with push notifications on... No way..

Why are people so afraid of chargers? I charge my phone throughout the day and leave it on the charger all night when I sleep. I never got why people dont charge their phone at night.
Also, this phone wont get two days of battery life.
