When I'm at home and getting -80 to -70 signal, I lose like 10% battery in 4 hours. When I'm at work and getting -120 to -100 signal, I lose like 50% battery in 4 hours.
Sucks....
Neither ROM nor CPU speed or scheduler or running apps or anything makes that big of a difference. The only single factor I know that can kill the battery faster is the screen.
I keep a charger at my desk, but I'm wondering if I can do anything to improve this situation. I tried JuiceDefender for a while. In theory it would help a lot, but it seemed to cause some problem where Grooveshark and some other apps kept trying to hit the internet and couldn't which seemed to kill my battery just as badly. Maybe if I get the pay version it would allow enough tweaking to help.
Any advice?
I'm noticing the same thing. Was at a bar the other night with really poor reception. I was only there for about 2-3 hours. Without really using my phone at all the battery dropped from about 75% to 15%. Meanwhile, at home where I get good reception I can routinely get 15-20 hours.
I definitely think signal quality substantially impacts the life.
My signals been crap since I updated my PRI. Don't know it its related just been doing it since then.
I moved recently and am in a little 'deadzone' area where I don't get very good 3G or 2G signal (thankfully its a short stay). When I leave my phone on, I found that I lose a tremendous amount of my battery (phone indicates that I am without signal 95-97% of the time typically) -- I had a blackberry curve before my evo and even that phone and its otherwise kickass (only good feature...) battery life would go down significantly or die from sitting over night.
What I have found that I can do to minimize the damage is turning off data and connecting to my local wifi and running some setCPU profiles locking the processor at 245mhz. Last night my battery decreased about 12% doing this.
Its funny because last week I was on vacation in south florida where I had awesome signal and if I turned my data off and connected the wifi, my battery literally would stay the same for 10 hour or so before ticking off a percent.
I'm running a stock rooted odexed ROM with Herver's #2 Kernel. I do not use a task killer or juice defender.

well yes, because you phone is continuously searching for a better quality signal.
Hey XDA
I'm having absolutely HORRIBLE battery life with my GIO. I've gone through extensive testing to find the root of the problem but nothing seems to be the cause. So far i've had to charge twice, maybe three times a day.
So here's the story. A couple of months ago I noticed my Gio's battery was dying quicker so I flashed another rom [Particle Mod] over it. I was happy, until I found out the problem persisted. Then I flashed a 2.3.7 Cyanogen mod, the battery still wasn't lasting and the battery life was only slightly worse owing to CYMOD.
I then flashed the GALAXYICS beta, and it's getting even worse. I've even bought new 1600mAh batteries to see if it was the battery's fault. Apparently not, so I went back to stock for a day or too to see what it was like, and I was still lucky to get 12hrs out of it with featherweight usage.
I simply do not know what to do, I've tried numerous battery mods [flashable zips etc] and they've only done a tiny bit. Lately I've been playing with clockspeeds but it seems to only make a difference if I raise the minimum speed, the extra top end performance is nice though.
So, what I'm saying is this normal for a Gio? Is it a hardware fault? software? 4th dimensional? I'm at a loss, and I think the infamous Samsung cell standby drain is to blame.
Attached is screenshots of general battery screen, Cell standby and the Graph. I've been switching between 2G and 3G, Airplane mode on and off, and listening to music for an hour or so and It seems to have utterly crippled the device doing simple tasks, and I've done EVERYTHING to minimize the drain by lowering screen brightness to %0, turning off vibration, animations, wifi, GPS, BT, radio, everything except google contacts sync and a couple of root things in between like deleting the batt stats.
The new batteries help somewhat, but I still can't last long enough for a single school day... FFUUUUU!
I really don't want to have to buy a new phone, I'm only 14 so I can't work to get one, and I can't just ask my parents because then I'm just being a spoilt brat. I want to make this phone last as long as possible [Until I can work for a Google Nexus or something] and the battery isn't helping.
Thanks for reading.
Yeah you're a spoiled brat. This is not great but not extraordinarily bad. My epic 4g touch spends the day on the charger.

Well, it seems to be all right with your battery. And your '1600 mAh' battery was just a fake. A lot of people get scores like this
What I am worried about is not so much the capacity, it's the RATE at which it drains. I see a lot of "stair steps" on my graphs so I'm not so sure, especially when checking the other phones in the house "a Galaxy Ace and 2 HTC Incredible S's] they seem to have a more consistent curve, I notice my batteries will drain by as much as %5 in half a minute, which is either a reporting bug or inconsistent strain.
Have you tried to do a wipe and test it with no installed apps?
Do not trust the "stairs", it is just bad reporting (as you said).
In my case when I switch on 3G or WiFi, it happens that the battery drops by 10% instantly.
The only value that is relevant is the total duration between a full charge (100% charge + several hours still plugged) and the "low battery" indicator.
According to my own experience, the things that drains the most are :
- 3G network : this is the main factor, by far.
If you can, try to stay in 2G mode most of the time, switch to 3G when needed, and as soon as not needed anymore go back to 2G.
- WiFi / BT
If you switch On/Off very often, or is always On and you moves very often (changing hotspot), then WiFi / BT will be a very important battery drain factor.
- Multimedia
Videos / MP3 drains battery a lot.
If you can, switch to "airplane mode" or switch off the phone during night.
Finally, with 3G / WiFi / Multimedia usage mix, a "One Day" autonomy is good.
I'm sorry but you will not find any smartphone that can pass "One Day" with that usage type.
With my own usage (very few calls, sms, wifi) and with above tricks, my Gio lasts 4-5 days.
PS : As you mentioned, available ROMs are very unequal as far as battery drain is concerned.
Stock ROMs (and moded ones like Adrenaline) are the champions of battery life, while ICS ROMs are the worst.
CM7.2 ROMs are in between.
I agree with Vilo76. When you don`t have wireless or 3g, or play any music/games, you can actually get a few days of life from your phone, but if you do some of the stuff i just said, the battery life is going down like crazy...
The only think you can do to get some bit of juice out of your phone is if you format your battery, but actually that is just for a better battery reading, not actually extending your battery life...
By the way, I can't figure out why phone manufacturers don't use more long lasting batteries ...
There are many many examples of batteries that are about the same size as a phone one, but deliver way more mAh.
Among others :
- House wireless alarms keypad batteries are the same size but can be as much as 3000mAh ...
- Classic cylindrical AA or AAA accu can be as much as 4000mAh ...
While a typical phone battery hardly ever exceed 1500mAh.
Okay, I'm back and I have some results for today
3G Is DEFINITELY using more in Australia on idle, while 2G is a bit less brutal
There is something cause my phone to wake intermittently, I've turned sync and location services, and killed any apps that may be checking the net etc, but it's still waking up with screen off.
---------------------------
Today I decided to do something bit extreme, I ran the phone an airplane mode all day with the original "dead" battery, I only lost %20 all day with 1hr or so music usage, phone standby is up but Cell standby isn't there at all [Obviously].
Something's telling me that's it the cell radio and whatever is waking my phone up is causing the suck. I'm upgrading to GalaxyICS CM9 beta10 today with a full dalvik, battery and cache wipe, so we'll see how that goes
----------------------------
MORE NEWS
Good news this time! I've installed a Cyanogen Mod 7.2 on their [The one that's updates through Goomanager] and the battery is holding steady at 100 idling for 1hr on 2G.... Not sure if I have to calibrate but I think I've fixed it, it's working better than stock!
Well, I just purchased a Note 2 and am still in the "evaluation phase". I really do like the phone, fast, amazing battery and awesome signal. However I am asking this because I ama wondering if I am getting all that I can be from my Galaxy Nexus before I decide to keep the Note 2 for $700+.
For reference I have recently been using the Euroskank CM10.1 releases with Franco's newest kernel and undervolting CPU to approximately the values in the LeanKernel Aggressive Undervolt levels as well as knocking down all IVA and CORE voltage 100mv.
I can generally stretch the Nexus' battery life to 13 or 14 hours, but that's with <2 hours of screen on time. If I am using it a lot 8 hours of battery life is lucky, if not less. This really isn't with any gaming or using it for listening to anything, just genrally Facebook and the internet. I do leave LTE on even though at work I can only get 3G. I have turned LTE off before but honestly I have never seen an increase in battery life from doing so. This goes to signal issue also, at work it will go to 30% or more time without signal and Cell Standby will be the second highest use of battery. I have a refurbed unit from Asurion that is version 10 and using the latest radios for CDMA and LTE. The Note 2 in the same usage environment reported 0% time without signal and Cell Standby was way down the list of power usage.
So, basically I am wondering, am I getting everything out of the Nexus that I can, or should I be getting better numbers. Maybe some of you on here can verify that the Note 2 is actually better for signal etc. or that I am just being delusional. Thanks in advance to all of you!
EDIT: Oops, meant to put this in the Questins section, accidentally put it here, Mods, please move!
No one?
Seriously? Even a piss off would be nice to hear, lol.
My signal is fine, my battery life is like yours (<2hr screen on) even with the OEM ext battery.

Thanks for the reply, good to hear my battery life isn't out of the ordinary. Signal does seem bad on mine though, I am going to call Asurion as this one runs unusually hot, uncofortably hot to hold even.
Yeah, mine gets fine signal, though the current radio firmware that came with the 4.1.1 OTA seems to have a problem hanging onto LTE signal indoors. I'm sure it'll get fixed in the next OTA (hopefully to 4.2.1). As far as battery life, it's what you would expect from an LTE phone...about 2.5 hours of screen-on time, maybe 3 if you're really lucky. Battery life can be affected by so many things like apps you have installed, screen time, cell signal, etc.
One thing I'll tell you, though...you'll find your battery life go up by at least 30% by keeping it connected to WiFi. If you're on a cell connection, your battery is going to zap a lot faster because as a matter of principle, cell modems are far more power-intensive than WiFi is because WiFi is a much shorter-range technology, thus the transmitters don't have to put out nearly as much power. Also, if not connected to WiFi, weak cell signals are going to drain your battery even faster than a stronger signal.
But, as long as you keep the phone on WiFi when you can, you'll find the battery life is no better or worse than most other LTE phones.

With WiFi, easily 15 hours with ~2 hours screen time. With LTE enabled, usually around 6-8 with ~1.5 hours of screen time. I also get pretty bad signal around my city.

Well the Note 2 destroys the Nexus in battery life and signal reception to be honest, but then again a 3100mAh battery should. I like the Nexus and I am trying to get myself to keep it over the Note because having AOSP rocks and so does saving like $850.
I see countless comments with people complaining about battery life not being good enough in most threads, and it being affected positively/negatively by updates.
I'm aware a lot of ROMs can have a very positive effect on battery life but I am more interested in the general overview – your battery life's life if you will! The reason I ask for your experiences is that I would like to qualitatively collect a bit of information from a fair few people and see what's to be seen.
It's worth noting that my latest HOX's battery life is exceptional and I believe it's down to a simple life/career change. It's really nothing new to someone who knows their fair share about batteries however I would be interested to compare.
So, list the times you wake up, take your phone off charge, put your phone back on charge, and go to sleep. If you can it would also be nice to know what your battery percentage is at certain points. It would also be interesting to know what hours you do on an average working week and in what sort of work environment (home/architect, office/marketing, shop/clothes retail etc).
If anyone can remember the things off the top of your head, even rough estimates just chuck then in the thread. I will then compare them all to my own personal habits.

Personally for me ICS was 4.0.4 was perfect, after update to JB it's really bad. On ICS i was loosing 1% of my battery during whole night on JB i can even loose 10% ; d. Overall battery drains faster during usage... all stock.
There's already a thread for battery stats.

Fantastic. I'm more interested in people's actual habits not stats about their battery because it only tells one half of the story. Like I mentioned this is more of a qualitative approach, so less battery stats.
I should of assumed that most people would be like more yourself so I will get straight to the point.
I have the benefit of working at home which means I can charge my phone whenever. I'm not forced to charge it over night; having it over charging for excessive amounts of time. I charge mine in the day and as a result I'm conscious when it hits 100% – I then unplug it. Other than natural degradation, I doubt I have ever damaged my battery in any way which has left me with a great battery life.
I was quite interested if most people charge their phones at night, go to sleep, unplug their phones when they wake up etc. This will severely accelerate the degradation of the battery.
well for me, ICS was bad...im using custom rom and various kernel to see which has the best battery life...all bad accept ncx 0.99....well some of the time its ok but some not...the battery percentage in ICS if not using will stay at 1% but for a 5 minute use, it will drop 10%...but amazingly, if you keep using in screen on, wifi or whatever, it will not drop that fast, well for me its ok....but now i have updated to JB still in stock, and the battery life is great.. i have watch HD movie using MX player in 2 hour and only drop 20%....when in ICS about 80%...big difference....i think stock kernel is best...
Well for me it's decent i mean yes it could be better but it's okay... heres my usage: i take it off the charge around 10 am when i wake up or so and it's off the charge till the next day morning with avarage 45-50% battery left and screan on time avarage 2:30 hours - 3 hours, sync with FB , hotmail and weather is On all the time as well is the wi-fi even when i sleep, my reception aint so great tho , around 2-3 bars top 4, 2g network, anyway my tops on the screan time would be around 6 hours with around 30% brightness idk how that guy managed to achive 6hours 20 mins on a single charge on medium brightness , could be jelly bean or maybe partitial charges ( i'm on ics btw ), anyway hox battery aint so bad as ppl may think, besides if you're lucky enough you'll get hox + battery into your hox ( 2100 ma ) which should provide avarage 6 hours + screan on time, tho i bet we could get around 8 with that battery. Hope this helps.
Ive got arhd and i got to say Im happy with my battery life, first I wasnt, when I went through a couple of charge cycles it got better and better. Now I can do 3.5 hours on screen time playing games and use it for atleast 24 hours with a mix of everything with watching videos to on the bus lol. So mines has been really good.
Battery has been pretty bad on any ROM. Now that I have ICJ421, my battery is near perfect. Yesterday I got 14h with 3h22m Screen On time.

I dont get it.. I got the phone 3 days ago, but if Im lucky, the phone lasts for maybe 6-7 hours?
It gets extremely hot when used in couple of minutes, and its like the battery is drained by something hidden.
On a night it loses about 6-7% in 6-8 hours of standby with data etc turned off
I have turned push, sync, NFC, smart screen and all that "smart" stuff off.. so I have no idea bout what drains the battery. Even the screen is on 50% and auto -_-
I have the korean version (I think?) the european version - bought in Denmaek, stock. Not rooted or anything - but is it possible to root the EU/KR edition or is it only for the Canada/Sprint edition?
Same for me. Hes obviously not using hes phone much and not on LTE.
The battery life of G on LTE is really terrible.
By the way mo on arent hot last days, probably they fixed it.
Web via LTE eats like 15%-20% per hour, reading a book on small bright is 3%-4% per hour

Is there any way to tunr of LTE/4G then? I'd rather have good battery and like 20mbit than a few hours battery and 45-50mbit download speed .. :laugh:
Battery life is consistently around 11.5-13 hrs with moderate to heavy usage.
My battery is crap too sometimes is ok ..
but it is just screen what drains .. and + if u browsing internet and u have flash enabled it is big drainer added .. needs more cpu power..
if u put mobile on eco mode turn down screen to 25%-30% turn all radios off u should be fine
download apps like battery calibration . or battery stats or juice defender

I'm really not an expert at this. I have also just opened my Optimus G, so I can't share my personal experience with this phone. However, the battery of my Lumia 920 needed around a week to function properly. The first three days I got heating and drain, almost 10% per hour, but now the phone lasts easily for two days with light usage. I was looking everywhere on different forums for hidden factors draining the battery, until I found a comment, where someone described this phenomenon: he said that a battery needs around 12 full cycles of drain and full recharge before optimal performance can be obtained. So from now on I will be more patient.
Then again, I'm new here, so other opinions are welcome.
eeemm that is not true i had phones over years and batt been always same..
it is all about usage ..
jut do test charge it fully and dont do nothing with it just ocasional phone calls and sms's and ull see then..

For me on jb v03 I get around 18-19 hours with around 3 hours screen time, but agree its all about usage.
I mean if you leave your phone off most of the day with your wifi and data turned off it will drain very slowly..
I find the biggest drain is always screen, cellular connection especially when you have poor signal, and wakelocks.

I had same xperience with my iPhone 5 so I hope its the same with my LG.
But for know I've installed JuiceDefender and disabled LTE (HSDAP+ i fast enough for my needs on the phone anyway)
exactly this is my problem ..
we traveling to the places while am in work and there are areas where is poor signal or no signal that means phone automaticaly boost its signal which is very big drain and if your mobile has no signal at all and u obviously set to automatic search it searching searching and draining hell lot!

this is true as well 4g signal is even stronger signal as previous 2g 3g drains so much plus when u surfing on the net!
when 4g will be standard the manufs will have to make new generation of batteries to stay last longer o LTE..

Phone idle refers to the amount of battery cell radios are using up when the phone is sleeping. I would recommend moving to an area with better reception and disabling data when unneeded.
Data is disabled (and wifi).
battery life is fantastic, i get roughly 5 hours on screen time, when i finish work i have 70 - 80% battery with 1.5 hours screen time
My battery life on CM.
Disappointed kinda, expected great improvement compared to stock rom
After few weeks of heavy usage, I am noticing the battery performance to improve considerably, I'm running stock 4.1.2. V10D
