[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?

Battery jumping

Good day everyone, I've been using CM9 for awhile now and its been an awesome ride so far. Everythings been working almost perfectly. Recently, my batteries(stock one) percentage level's been Jumping up and down...a lot. For instance, I woke up to it (while off) having 100% on the indicator, turned it on, and it dropped to 51%, re-booted it to see if that'd help but it dropped again to 12%. This kindof things been happening for awhile and still with Alpha 2. Should I just get a replacement from sprint? Or is there a workaround.
Also, Music's apparently been taking up to as much as 40% of my battery usage even though If don't even have it activated at the moment. I've tried deleting the apk but it appears com.android..., I may just be being a noob, but any help?

Jump" is typical when you don't power off completely and then power back on no work around other than turn it off leave the battery out for like 3 or 4 minutes and power it back up

Have you tried calibrating ur battery? Give that a try and see if that doesn't stop it completely.

Apparently calibrating the battery according to some Android Engineer does nothing. The percentage you have left is directly related to the voltage of the battery. So if you are at 3.95 volts, that roughly corresponds to 50% with a range of 3.7 to 4.2 Volts on the battery. What the OP saw is the bbb...battery boot bug. If you are rebooting and you are lower than 70% do it while plugged into something. If it does happen as Biggie stated, simply remove the battery for a couple of minutes and reboot. It is a false report to the phone.

This has almost always been a issue for me when I flash anything new. It stays that way for until I deplete the battery, connect and leave connected til 100%, deplete the battery and follow the same process for about 3 full cycles and then all is well! Leaving battery out for a breather sometimes helps but I installed an app that has a widget and it keeps the regulating kinda monitered so I can be a little more at ease. Will post directly after this. But I also noticed that there have been times when the readout was a very low battery red [but I knew couldn't be true] and after I put it in airplane mode and didn't bother it for 5-10 minutes when I looked back again, battery would be yellow almost back to showing good and my battery stats show the levels increased. I think cm9 can't handle too much at one time anyways
Edit: that app I think is called battery info. Its pretty simple =) hope it helps! L8rz
Edit2: that app is listed in market as battery widget not battery info

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
Sent from my Galaxy Nexus using Tapatalk

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.

Battery Drains when not in use/sleep

Am I in need a new battery? Which ever ROM I use this happens.

Need a little bit more information then that in order to help
Sent from my R800x using XDA

Left the phone idle after I pulled the charger. Came back and it's already below 90% (87) I haven't used any apps,as you see only the usual stuff show up.

Researched a bit and heard cell standby could be the issue,are mine normal? Can't tell.

How long was it off the charger for? Also I would be more worried about wifi, if your actually using wifi then yeah leave it turned on but if you're letting the phone just sit there I would try turning it off but I don't user wifi so I'm not sure. You can also try turning the brightness settings down.other then that it looks normal to me.
Sent from my R800x using XDA

Brightness is always below 50%,I keep around 25%.
So 2 hours off the charger,wifi on and idle,87% is normal? Everytime I turn it on just to check the battery it drops 2%, I don't think that's normal.

Honestly that's probably normal if you were away for an hour or so or if you left wifi on. Battery life also depends on which kernel you're using as well.

I'm using DooMKernel v14

Installed Juice Defender, did some tests and just after I unplug, it took a while to go down to 99% took 10 minutes while watching YouTube on 3G but as it got down to 95 % the battery just drains quickly , went to 85% in 5 minutes while browsing the web

i noticed the same thing
i lost my old charger so i bought a new one and thats when i first started having this issue.
phone would seem to charge faster than before but died faster as well when using this charger. (this was my work charger). at home i use laptop to charge and takes longer but lasts longer.
also noticed phone got warmer when charging at work. so i returned that charger and got a different one and problem solved.
so if your using a different charger recently a new one may help

WiFi seems the culprit. Maybe Google how to set the wifi scanning interval

I'll try a different charger. The phone does get hot when plugged in.

Better Battery stats.
I'll bet one of your apps (a wifi app) isnt sleeping, and thats why you are losing the battery.

****ty battery

Time to replace a battery, or is something wrong here?

Using android is like changing a new phone every month!

Better check you apps behaviour and syncs with BetterBatteryStatts and cpu spy for deep sleep. No way a battery drains that fast normaly.

Interesting thing is, I just did a full wipe/factory restore, couldn't be an issue with my apps, could it? Gonna go log my battery in the mean while

Could it be due to this process "audioOut_2"?
Dont have vibes installed though, yet somehow this is preventing phone from sleeping.
Will try with second handset to see if this is an issue with rebooting phone on silent mode

how many screen time? have you put you phone in a hot zone? have yoy been playing while charging for a long time? i say it because it is known that some samsung batteries inflate themselves and decrease the battery life to like about 15 minutes so look if the battery is normal or a bit rounded (fat battery)
hope it helped,

Hot zone meaning? I haven't been abusing my phone, but when I play some games/surf the Web, the battery seems to die at almost twice the speed it did before.
If buying a new battery would solve this issue, then I would buy without hesitation! I'm just scared that the battery condition is not the main issue with this drain.
Currently doing a full drain/charge to recalibrate the battery

by hot zone I mean let the phone in the sun or somewhere when the temperature is high. I recommend you to check your battery physically, I mean open the back of the phone and see if the battery is in the same condition as when you received it. As I said before the main problem could be that your battery have been inflated if is this you must replace it not only because the bad performance but also because it is really dangerous(there are acids in there and if it explote..)
However it seems more like a continous draining try calibrating as you said with battery calibration or similars. If the battery starts to decrease its life (i mean today lasts 5h., tomorrow 3h.) it is almost sure what i said about the battery.
hope i helped you somehow
