Alright first of all, i want start off by saying that i LOVE this phone, both in terms of hardware and software, however, theres is a HUGE problem that i just can't get through and its the battery of this phone...
It is simply unbearable.
I have posted the screenshots. This screenshot is taken after 1 whole night of charging. In 5 hours or so time, I've use the music app for about 1 hour, talked on the phone for about 5-10min and sent about 10 text messages. I didn't do any web browsing/videos/gaming. I have also disabled LTE and turned my brightness to minimum with eco mode on. These small things drained my battery from 100% to less than 10% within 5 hours which i find to be completely unacceptable.
Last night, with me browsing the web on the bus for about an hour or so, it drained my battery from 85% to 3% by the time i got home...
I've looked at the battery life thread and it seems like im the only one experiencing this issue. Also not only does it drain SUPER fast, it takes a good 4 to 5 hours to recharge this thing. Which means it takes longer to charge than to use up even with minimal use...
Do I have a faulty phone and should I get it replaced???
Something's amiss. The only time that I've gotten less than 10 hours, is when I had my work email connection set up to "always connected" and wifi was turned on. Even then, I got 9+ hours of battery life.
Disabling lte is part of the problem. When the phone is in 3g, it uses fast dormancy which LG did not implement very well and it runs the CPU constantly. I encourage you to contact LG and your carrier and complain. don't let them tell you about background data or applications running the battery down. With the same apps running, this does not happen on lte. This can easily be verified by enabling debugging and then capturing a logcat from adb with lte both enabled and disabled. It will show fast dormancy trying to set network states every second. I spent a lot of time trying to get this issue recognized, but they kept saying that it had not been reported and was not a known issue. Let's make it a known issue so they will fix it.
How about actually showing us what you used instead of screen shots of %.... would be helpful...

I'm also getting about 5ish hours on a charge. And, when I recharge at the office with the usb cord, it's a "trickle charge" that's so slow it's ridiculous.

Yeah, I've been quite impressed with my battery life on this thing. I made it from 6:30am spent about 2 hours tweaking it and setting it up, then messed around with it through the day. By supper time I plugged it in and it was at 63%.
I don't have the phone, but right off the bat i'd say it was whatever was causing your mediaserver to go nuts. Either some media app, YouTube, gallery etc, wouldn't say its a faulty unit, just mediaserver gone rogue
And damn i want this phone...

Well, a little update to this thread, i've disabled every different kind of syncing possible and i've been able to pretty much double my battery life from before, which is a lot better but i still wouldn't consider this to be good battery life.
I've been reading many posts regarding battery life, and it seems like there is some issue within the software that prevents the phone from going into deep sleep which is causing the lack luster battery life. This issue is on both the optimus g and the nexus 4, so i hope the devs may look into this issue when they are building custom roms for these two devices!

You definitely seem to have some weird issue's. My Optimus is great for battery life. My previous phone was an Xperia Arc and this has significantly better battery life without even running it in "eco mode". The only time I have noticed less then stellar battery life was when I had some app's running in the back ground that would keep refreshing/updating which kill's the battery.
Androids usage readings are inaccurate. Please consult this: http://forum.xda-developers.com/showthread.php?t=1179809
From what the picture shows I would guess its your 4G connection. A Hardware fault is improbable. And forget these things like "eco mode". Even if they underclock your cpu it won't give you a real benefit,
I've had great battery life on mine. Even when I've been geeking out on the device for several hours during the day.
Perhaps you are on the cusp of LTE coverage? If so, then the radio can kill your battery while looking for a signal.

I also have amazing battery life IMO, coming from a Galaxy S. I have no LTE in this area so am using only HSPA. Using the phone with casual use, I can easily go a full 24 hours on a charge. With very very heavy use I can go from 8 am till around 11 PM. I am very happy with the battery life overall. I'm running on "eco mode" FWIW.

My Desire Z has been a battery killer recently. I have tried different radios and roms and it still sucks excessive power. Even on Airplane mode battery monitor widget was giving ~50mah per hour drain with the screen off.
I have both a stock battery and a Mugen 1800ma battery and this seems excessive. I checked and there were no applications keeping the phone awake either. At work with minimal usage my phone easily drains over 30% of the Mugen battery. Signal isn't a problem either because I work 280 metres away from a Bell cell tower and have full signal at work all the time. I'm starting to think that something is wrong with my phone.

I had a similar problem with a stock battery of mine and ended up recalling it with my phone provider and they shipped me a new one. They (T-Mobile) said "not all batteries were created equal" and that sometimes even without water-damage, certain batteries lose their shelf-life much faster than others.
Since you're telling us that both your stock and your after-market are draining at a near equal pace regardless, this might be an indicator that it isn't your battery.
I had to return my original G2 to T-Mobile because of hardware malfunctioning in several areas, namely the audio mechanisms. If you're using a relatively new phone, and/or a refurbished phone, I wouldn't be surprised if you are experiencing similar problems.

Have you tried calibrating? Charging to full, wiping batt stats, discharging/charging back to full uninterrupted? The link below is a great calibration tool.... very convenient. I wipe stats after every ROM flash and keep an eye on CPU/RAM usage with Watchdog lite. Battery life is always good.

how long does the battery last for aprox in standby and with regular use. if it dies faster then 3days on standby or less then a day with regular use there may be an issue im just wanting to know the time span of your battery....
also i had hardware issues with the g2 too. my radio sucked balls, i couldnt even keep signal in a call longer then 3 seconds and my wifi would just cut out for periods of hours at a time... im wondering if the manufacturing is becoming sloppy and they might be lacking quality control. i admit there is a lot to the phone but simple things like battery quality and signal quality should be checked regularly.
with the g2 i frequently hear things like this, battery, screen failures or behind the screen cracks, unresponsive touch screen and black spots, bad radio signals, color leakage and most commonly issues with the keyboard.

Well if battery monitor widget is correct my phone would last 26 hours in airplane mode (36 with my mugen battery) with the screen off (I tested this with almost every user app uninstalled)
Edit:
Considering there was a guy who left his old Hero with CM7 in airplane mode and that it lasted for 30 days before the battery died... I find this quite discouraging

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.

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.

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.

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.

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.

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.
I'm getting some really good battery life with light usage so far.
1d 3h 33m
Edit
I m getting similar results, light usage I unplug at 7am and plug back in at 1am with ~50% battery left.
This screenshot doesnt say much, tap at the graph - that the screen to show off
WIFI seems to be much better. With my LTE on I can barely charge the phone LOL. I wouldn't trade 20 Mbps down for bettery life.
I'd say my experience has been the opposite of what's been reported. With low to medium usage, I'm lucky to get 8 hours. I don't think I'm doing anything wrong. I use setCPU to put my phone in battery saving mode and underclocked all the way when the screen's off. I kill apps whenever I notice a lot are running. I dunno.

I've never been an iPhone fan, but since the iPhone 4 the battery has been phenomenal. Battery life is constantly improving on Android phones, but it seems like every time something new is introduced it gets significantly worse. The 720p screen and LTE radio don't seem to be helping the battery cause. In the Nitro's defense, I haven't carried it an entire day to see how it works out for me. My Inspire could charge completely in about 2 hours, this phone will have changed less than 50%. But I have 20 Mbps download!!!

Well, I'll be damned. setCPU was the problem. My battery life is lasting much longer now. With medium usage I'm at about 15 hours on a charge and have 7% left. If anybody is having a problem and is using setCPU, don't take my word for it, uninstall setCPU and see for yourself.

If you're using a USB port to charge that could be why it's so slow.

Good point. Now that you mention it, it does appear to charge faster when plugged into the wall. Well that kind of sucks. This thing takes forever to charge. I'll try with a wall adapter when I am home again and let you know what I find out.
It's kind of hard to always have a wall charger with me though.
It is not blackberry crazy short timing charges but I can charge it less than 2 hours from around 20% left using stock 1.5 amp wall charger. It definitely does not charge long.

Am I correct to assume that the 2.1amp car charger would charge better/faster than the 1.5amp wall charger? I ask because with the wall charger I still consume power faster than the charger can keep up while watching SlingPlayer mobile.
Probably so, this phone is a battery draining beast. Every review I've read says LTE phones have terrible battery life. LG should have had an option to disable it and 3G. Oh well, I'll live with it while streaming on my 22 Mbps DL connection.

That's just it though... I'm not on LTE while using SlingPlayer. I'm on 4G out in the field. My car charger doesn't say what it is, but I assume it's 1.5amp. I download "Advanced Task Killer" app, but everything I "kill" comes right back up. I think there's too much crap running and sucking down the battery. I really need to figure out how to root and freeze bloatware crap.

Same here. Battery life was a concern for me when I was first considering the phone. But I found that I can go a full day on a single charge. so I don't even worry about it anymore.
I hate to be the guy that asks this, but I just want to make sure as from what I understand this is different from phone to phone. From what I understand, Li-Ion batteries, like the GN2's, do not have a memory effect of any kind? And thus all battery calibration rituals and nonsense are entirely pointless for this handset?
The reason I ask is because I wasn't able to charge the device to 100% before use like I was always told to do with new phones. My device was turned on and used until it drained to around 10% at which point it was charged to 100%.
Now, after 2 weeks of use, I feel that my battery is not as good as it should be. I'm barely able to get more that 12 hours. I'd be happy to post some battery graphs in the morning.
One last thing, if I did mess up my battery, or if my battery is messed up or less functional than it should be, would buying a new battery fix all my problems?
Youvare right. All that calibration stuff is nonsense.
I have never charged my phone to full before using and draining the battery and my phone still lasts all day on mostly heavy use.
Could you post your batt stats?

Today I ran my phone with the "lowest" possible settings, that is lowest brightness, CPU power saving, and no haptic feedback. I did not turn off wifi. Doing this I was able to get a surprising 16 hours, although you can see from the graph that I didn't use my phone as much. Attached I have a screenshot of what it's like with the highest possible settings (no power saving stuff, and brightness all the way up, but no GPS). Sorry I don't have a pic of the percentages for the high settings, I never thought to do that.
What concerns me the most is this: even with the lowest settings, I'm only getting 2 hours screen time. (last pic)
What's interesting is that you would think that if I'm getting such poor screen time, there would be something else using a lot of battery, but there isn't. This led me to believe the problem was with the battery. I discovered a pretty big scratch on my screen the other day, and I have some monthly insurance plan from best buy, so I was thinking of just getting a new one. The longer I wait to get a new one, the harder it will be to set up everything again. lol
I noticed that compared to other GN2s, mine seems to wake up a lot when the screen isn't on. The awake periods tend to correspond with drops in battery and also when I have a poor signal. Could this be caused by my phone trying to look for signal and using battery?
Yes poor signal that results in the phone searching for better 3g/2g will drain the batteey faster.
Can you try using it in airplane mode with wifi only for a day and see how that goes?
Also install Better Battery Stats and after a day or so of normal usage check your partial unlocks to see if a rogue app is preventing deep sleep and sucking your juice.

Yeah it us definitely your signal playing a role. Also you have a lot of wakelocks showing up

Dude you have major wakelocks that eat up 80 % of your battery!
Go to application manager and remove all the apps you don't use.
K, I agree with my week signal using battery. I only have 75 apps on my phone and they're all pretty mainstream, no obscure apps. Right now im in school with 86% battery, I'm turning on airplane mode now. I have noticed however that when I clear my ram it closes like 50-60 processes each time. I am always closing my apps, but 50 seems extremely high. im gonna turn on airplane mode and see how that goes...
thanks!
Yes, you do have poor signal but that's not all. You have terrible wakelocks pal. Install BBS and monitor which apps are the culprit. It's not about 75 apps, even 2 or 3 bad apps, which have hidden advertisement going on could suck your battery flat in no time.
So first thing, install BBS. 2h screen on time is horrible!
Btw- If you're on 3G, try to switch to 2G. Difference will be unthinkable.

Thanks everyone! I'm really loaded with school work, so I don't have a lot of time right now. But long story short, airplane mode saves my battery like crazy. I started school with 86%, turned on airplane mode, and I'm at 79% right now! more later
Is it safe to say I fixed it?
3h screen over 2 days isnt bad right? Perhaps just a bit worse than what others are getting?
