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.

It doesn't get better...get used to it until its fixed in an update , along with the other big issues.

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.

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.
Hello all,
Am i the only one that is having problems with the battery life on the galaxy gio?
I charged the phone today at 5 in the afternoon, by 8(3 hours after) 70% of battery, charged it with the wall charger and i rebooted it when the battery was full to close all tasks.
In 3 hours without any wifi, only 1 sms received, no calls and no other tasks was executed i lost 30%.
What can i do to improve the battery?
Are you experiencing any similar problems?

You can wipe battery stats, and turn things like gps wifi data autosync unused apps etc off, for some things you need root acces

What rom you have ?
I have problems with battery life too...but because i play games. Is weird because you didn't do nothing like browsing or play games and your battery was eaten.
Try a full wipe.
Also search the market for PowerTutor, it might be able to help finding what eats your battery, as what you describe this is not normal.
If you've rooted your phone you can calibrate your battery. There's an app for this in the market. It just wipes the battery stats file and creates a new one. I've head that it is good with every rom change to calibrate the battery Hope this helps! GL!
Actually it's good to flash every new ROM when you have fully charged battery. If you fail to do this you'll have to calibrate the battery and it might not be easy to do right the first time.
SO much easier to flash having full power
Battery stats wiping
IIRC google denied that battery stats wiping would actually increase the battery life: http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
I assume, you have things like WiFi, BT or GPS turned off... Then you maybe might try another launcher. Samsung's TouchWiz is quite a power eater.

It won't increase battery life, true, but think - when you unplug the charger? When your phone says "100% charged", right? And if your battery starts are wrong the phone may say "I'm charged" when it's actually, say, 40% charged or whatever.
Wiping stats should also provide more accurate battery indicator when it gathers new stats after some usage.

In my experience the battery indicator may work a bit odd (e.g. it goes fast to 40% then stays there for ages). But it didn't keep the battery from charging to full, even when it indicated 100% it still kept charging. But to stay in the topic, clearing the stats might help the "dropping by 30% really fast" issue
Yup, that's what I was talking about - wiping stats won't improve battery life, but might fix indicator accuracy
It could be your background applications eat too much mobile data. Check out your background applications and disable them. Stick with 2G also it improves battery life a lot
if the phone and battery are ok, and you don't have Wifi/BT/3G/EDGE/max_screen_brightness/ or high CPU usage background apps, you should get something like in the attached picture:
AT least for me CM7.2 really improved battery life up to 2 (TWO) days!
Unfortunately CM9 ruined this again and brought it back for ~8h...

Sent from my GT-S5660 using xda premium
You can use CM 7.2 http://forum.xda-developers.com/showthread.php?t=1381355
It is stable and saves battery better than stock rom.
Another thing to check is that Wifi is set to disable when the screen turns off or when plugged in... If not, you can loose 50% battery life in 6 hours. (Which i did once. NOT FUN.)
As well, apps that sync in the background. Ie, mail checking your inbox every hour for new mail; facebook, twitter, myspace checking for new notifications every hour; leaving apps using GPS running in the background like Navigation, My Tracks, etc. Those sorts of things can drain a battery really quickly, beacuse it has to wake up the phone, get the phone to get the required data over the cellular network then go back to sleep again, instead of just letting the phone sleep.
Another thing you can do is to make sure you kill apps. IE, don't use the home button to exit the app, use the back button. That will kill the app instead of leaving it running in the background.
Its kinda funny, this is all stuff people have mentioned already, but it seriously can be the difference between a half a day and a whole day on a battery...
I get 3-4 hours battery life at best I see people saying they get 10 hours I don't see how that is possible? Is my phone a dud or what this is very frustrating. It does the samething On the extended 2100mah battery. I'm running aopk milestone 4 and glados kernel
Sent from my Galaxy Nexus using xda premium
It looks like you were had screen on for close to 2 hours and made a phone call, albeit short. This is normal battery life for as much as you use the device.
You should try manually sync or set the syncing interval as high as possible.
Wifi always ON doesn't affect the battery life unless your wireless connection is weak/unstable.
Lower your screen's brightness or use Auto Brightness.
Fully charge your phone and let it alone for 2, 3 hours and check how much battery drains. If it drains 3-4% in idle mode, it's normal. Check also if your phone wakes up a lot, maybe some apps are running in the background and they wake your phone up frequently.
Hope it helps.
I used to have really poor battery life and like you wondered how people managed to get the stats I was seeing here.
I recently decided to do a factory reset for a different reason and to my surprise my battery life has improved incredibly. Yesterday I got over 18 hours in total with over 4 hours on screen time. This was with the stock gsm battery. Granted I was using wifi throughout but I was lucky to get 8 hours before the reset, even with wifi. With 3g I'm now getting 14 hours easily with over 3 hours screen time.
My point is if you've never done a factory reset, you may want to give it a go.

It's a bit hard to diagnose the problem based on only a screenshot of your battery stats.
Since your screen is using over 50% of your battery life, my guess is that you just had your screen on for about two hours of the total two hours and forty-five minutes. It's normal to not get more than about two hours of screen time. (Tap on the Screen part of battery stats to get more info on how long the screen was on for.)
In my experience with three Android phones (MyTouch 3G, MyTouch 4G, Galaxy Nexus), all the usual tips to conserve battery life pretty much do nothing to improve battery life: turning off syncing and background data, turning off wireless, don't use widgets, turn off GPS, etc.
Pretty much there are two big battery suckers on Android phones and particularly the Galaxy Nexus--the screen being on and LTE being on. If you dim the screen or just keep it off, you will seriously prolong the battery life. And if you use CDMA only, you will also seriously prolong your phone's battery life.
That said, it's also possible something is wrong with your phone... or your battery. We can't know just from the screenshot you posted.
This looks normal. How much screen on time do you have?

These kids these days...
So I bought my ATT GS3 out in Los Angeles this summer and then I returned to New Jersey to find that I have horrible battery life. It was not right away so this could be completely unrelated. As of right now my phone is at 75% and I let it drain while i was sleeping for 10.5 hours. I have tried several different roms which are usually good the first two days and then after that the battery life is bad again. I thought it may be some application I have installed so I removed a few of the ones I remembered downloading since I got back to NJ. I also updated to the latest radio ending in H9 because I was two behind when I checked. I have attached some battery information below. Any help anyone could provide would be great. I have tried Juice Defender which did save some battery life but it also caused a problem where I couldn't use the internet for 10 seconds after I wake the phone.
U need a Rom with cell standby fix
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
I thought the cell standby problem only effected the international GS3? If the cell standby fix was the problem then I shouldn't actually be draining that low right? Something must be draining the battery then. Google maps is probably draining the battery but how do I stop that from happening?

Just another observation. Battery tends to drain faster if you leave it in your pocket. If you flash a rom, you might have to calibrate the battery stats. I only lose 1% every 2 hours overnight if I leave it on a cold surface.

So I have tried a few different roms and I'm still not happy with the battery life. I calibrate the battery after every rom installed and I usually keep that rom for atleast 2 days to test it. Right now I'm on AOKP. If the phone is on standby whats the general %/hr? When I go to sleep my phone drops from 92%-75% for about 10-11 hours (on desk at temp 60F). By Apocalypse487's response I should only see a drop of 5-6 % over night when I see 17%. Am I supposed to me losing this much battery life over night? To me I feel like I barely use my phone. Today wasn't too bad with 1 hr with screen on and about 1 hr in calls. I made it about 1 day 1 hour 36min on battery. My phone was sleeping for about 23.5 hours. Is this the typical battery life or is something wrong with mine? Tonight I'm going to try juicedefender and see if that helps.

I'm using ParanoidAndroid based off of CM10. Version 2.16 of PA gave me the best battery life. Try that. Certain Roms have better battery management, but that probably depends on the kernel. PA uses stock.

I'll give ParanoidAndroid a try and see what that does. So Juicedefender ended up making it so I only lost 1% over 9 hours. Thats pretty good. Way better than I wanted. So what could be draining the power over night. Is it because my data is on all the time but shut off when using Juicedefender?
I use Trinue 2, and I use an app called Go Power Master.
In GPM you can setup options that will turn off mobile data/gps/wifi when the screen is turned off, will automatically turn them back on when the screen is back on.
Those things little things I find can make a big difference for the battery to last throughout the day.

It's as Sianspheric says, common things like gps, data, and wifi uses power. I just started using Juicedefender since my friend told me it helps. Also download battery calibration. It's a root only app. Don't let your device discharge completely. It's bad for Lithium Ion batteries. That will clear out any bad data from Samsung.
