[Q] bad battery??

I have been using the lte g.nexus for about two weeks now and i cannot stand the battery life let me explain
Im on screen timeout 15 sec auto brightness.
Operating on 3g mode only and my average batt time is abouy 4 hours of moderate to heavy use(no bluetooth r gps included) ive heard stories of batt conditioning when i got my g.nexus i charged it to green and immediately begin using it. I even let it drain to zero the first two charge cycles. I dont have any syncing apps doing auto sync except my google account and no one app seems to be sucking juice the screen is always using between 40%-60% in the usage stats is this normal i.never had this problem with my bionic.

that F'ing ridiculous that you are only getting a few hours on your g-nex especially since you have turned a lot of things off or to a minimum. i would either go to a verizon store to try to get a replacement or purchase an extended battery.

Not trying to hijack this thread but I'm starting to think my battery is bad too. I've been giving it time because this is only my 4th day with it, but its just atrocious.
Yesterday: charged to 100% and took off charger immediately around 4 pm. After a moderate amount of texting, 10 minute phone call, and my 4 Gmail accounts syncing in the background on 3g the whole time, the battery died around 11pm. The screen on time was maybe 1.5 hours.
I'm running Android Revolution rom with the included stock kernel. Everyone reports about how awesome the battery life is with that rom, but if 7 hours is good battery life then I don't know what to expect.

Im starting to wonder if the phone or either the battery is at fault because i see a lot of usera spread out across the net complaining of similar problems. Is there is a certain way to traim the batteru the first day or so because i love this phone but i refuse to buy an ext. Batt jus to make it thru a work shift.only on 3g ..anyone else having this problem or know of a fix?

I've heard some glitch about the camera sensor staying on in the background in a different thread. Search for it in xda

My battery was only worknig for a few hours with the extended battery when i looked at the battery usage it said 70% mediaserver. looked up online and it said if you have a picture or vid that is corrupted it can cause mediaserver to keep trying which i had a photo gallery widget on home screen. when i deleted img and deleted widget im now getting like 10x more battery life.

I am getting good battery life.
During my sleep or when my phone is idle or when I know I am not using it for a long period of time, I switch my phone to 2G.
Below is a screenshot of my battery usage during a long period of idle (overnight when I am sleeping)

I only switch it to 3G when I am actively using the Internet for surfing websites, Facebooking, Youtube, uploading photos or video.
Below is a screenshot of my usage from light to moderate to heavy.

I went into the bathroom with full charge and after I did my daily deed(s) I went down to 43% with brightness turned all the way down and only running xda app. wtf gives?

A single screen shot shows us absolutely NOTHING about battery life.
Your battery is also almost full...
Use the phone a full day 100% to 5%, then screenshot your overview, graph, screen on, awake, and signal times. THEN we'll be able to tell.

My first day was like this after charging it for the first time when immediately opened it. I found my brightness to be all the way up by default and set it to auto, substantially improving my battery life.

Still means absolutely nothing. Use it 100% to 5% and then report your usage.

I'm using liquidsmooth 1.3, just got this...is this on par or could I be doing better? Didn't browse the web much though, only lurked around xda cos I noticed chrome really sucks the juice

battery life is definitely improved on 4.0.4 , i'm getting between 45min-1hr more screen ON time (mostly surfing and reading xda) than on 4.0.2
i use live wallpaper and autobrightness, wifi always ON, everything stock with no tweaks, stock 1750mAh battery

Can you also post the battery voltage when you almost depleted your battery?
It can let us to see if the battery is correctly calibrated to show the proper percentage value. I encountered up to 1 hour different in screen on time with a non calibrated GN.
To know your voltage, dial *#*#4636#*#* (*#*#info#*#*) (no need press call).
Go to battery info and see the battery voltage value.

The galaxy nexus will always get awful battery. I have never gotten over 2.5h screen time and.I have tried every rom, literally. I can't really get over 14h stanbdy either.

I can verify I seem to have better battery life after the 4.04 update.

Did I get a defective battery?

Just got my s3 like a week or so. I made a mistake and not charge it initially (thought it was a myth). I used my battery all the way to 17%. Now my battery only average up to 2 hours screen on. My sister who also got the phone as the same time has about right hour screen on time. Did I screw up or it's just my battery being defective
EDIT: attached is the battery stats

What's brightness set to, and what are you doing while the screen is on? You on WiFi most of the time?

Well, when I'm in door, I use low brightness most of the time. Only when I'm outside I would use auto brightness. Since I'm in wifi zone most of the time, yes I do have wifi on. I mostly use my phone for twitter, web browsing, and youtube, nothing heavy like gaming or benchmark.

Hard to say if its defective but I've definitely seen a lot better battery. It might not hurt to try and get a new one.

you should calibrate your battery a couple times once you get the phone. do it a couple times and it will fix itself. also check all your syncing settings. this phone will deplete a battery in 5-6 hours if fully charged and phone brightness is up all the way while watching videos.

Calibrating batteries is a myth from the days of older battery technology. Draining your battery to 0 on purpose is actually killing your battery faster because you just used up one cycle.

There's a bug on stock that makes cell standby much higher than it really is. So I wouldn't worry too much about that.
Also, Google Chrome is a huge battery killer for some reason. Consider switching to a different browser?

Still having the original battery in my vibrant and getting 8-9 hour charges while killing the battery 100% and charging it up once a week does nothing? Same thing for my g2x. I get about 10-11 hours on the thing daily original battery as well. If anything and you're not rooted to delete battery stats, its a good thing to do a couple times. I don't think I have hurt the battery at all, and if anything they still last very long...

Post a Screenshot of your battery drain in the settings and give details about your setup. And what is fast in your opinion? 1% /hour?
Maybe you should buy the extended battery kit?

try flashing different kernels and see which one suits u the best.every phone is different.u may also wanna underclock and undervolt. also change the rom may b if changing kernel doesnot work.ine suggestion.XenonHD rom with its stock kernel.

The stock battery is a joke at 1800 and the extended is 2100...I had both and both sucked although the 2100 was a lil better. I have the 3800 Seiko battery now and that will last me all day. Makes the phone thicker but its better then charging all day and worrying about what's killing your battery.

Turn off features when not being used like data NFC GPS.
Also avoid auto task killers

How much does it drain in one hour? Battery drain depends on many factors. The mains ones would be what kernel and ROM you are running as well as what "features" you have turned on. For example I am running CM10.1 with the stock CM kernel and I usually get around 16-18 hours of battery life with 1.5-2 hours of screen time.. that is with all of the features (gps, NFC, etc.) turned OFF.

Refer to my post, partner

How on earth can you drain a 3800mAh battery in one day? Nonstop internet radio AND 3d gaming on full display brightness?

I am currently using PA rom with franco kernel. Normal day = roughly 13-15 hours ish.
By normal day I mean around 30 minutes of talk time, about 1 hour ish web browsing and like what, 30 minutes ish of youtube? Of course, sometimes I am free and end up playing games on it for couple hours lol, but the stock battery seems to be plenty enough to me.

My battery makes it about 15-17 hours,with about 1 hour gaming,1 hour browsing and talk time around 1,5 hours...Xylon + Purity Kernel!

It is what it is. This is Wi-Fi only on this charge:

Turn data off when not using it. You can download a widget for that.
Keep screen brightness down low.
If rooted use setcpu and choose a screen off profile of 350mhz maximum - I find this a real benefit.

Battery is ****ed up.

I was always unsatisfied with my battery life, but now it's gone too far!
1. No matter how long I charge it, at the very second I unplug it it goes down to 99%.
2. It doesn't even go down correctly, one moment it's 65% and the other it's 58%. Always.
3. It drains soooooo fast even though I do nothing with it!!!!
Here are some pictures
1. This is 17 minutes after unplugging it, all I did was to put music on [earphones] and check if my girlfriend was online on Whatsapp.

2. That's after a minute and a half, 2% less, doing nothing but listening to music with my screen off!
3. One minute later..
4. Sixteen minutes later, phone is idle and untouched [not even music, I started my shift]
5. Again, idle.
It lasts 3 hours tops!!!! What the hell do I do.

This app already told you the culprit! Your getting wakelocks so an app you installed is keeping the device awake all the time. The rest is for you to figure out partner . Use the search function on XDA and you will find all the info you need.

Ok might be but to the level where the phone doesn't last 3 hours? That's not cool. It should be lasting more even with heavy using.

yeah you're right, it should last more anyway! maybe it's the rom.. what rom are you using? or maybe the battery failed. it happened to me with another phone, basically i was in the seaside with about 38°C the phone was boiling hot, the battery was fully charged but in about 20 mins it was at 5% without even using it then it died. since then that battery never worked again and i had to buy a new one. do you remember if you had a similar situation or if your phone overheated for any other reason (maybe while charging or near a heat source)?

I use Android Revolution HD.
It got heated a few times but not too hot, and besides, I read that it happens to everyone..
