1. Root
2. Download NoBloat Free from the Play Shop (Market) and install.
3. Trim out unnecessary system services via this website: http://androidadvices.com/optimize-lg-nitro-hd-phone-performance-removing-bloatware/
After that was said and done, the battery life on my P930 was noticeably better.

Flash my ROM (see sig)

did u try calibrating the battery with any of the free software on the market !
i used to get 3 hours "seriously" out of this phone ... after deploating and calibration it can last 12 hours with heavy use !

I've started using an external battery charger (one of the official lg ones from Ebay) and an extra battery, and just swap them out when my phone dies, and I've noticed on the few occasions where I charge my phone by plugging it in, even though it says 100% (and I've done all the battery calibrations and everything) it doesn't last as long as when I pop in a fully externally charged battery.

My device battery life also got better in comparison to the first days i used it. But for some reason i experience some strange usage right now.
For example:
In the morning from 7 - 10am 100%... later 10% in 15 minutes, with phone in standby-mode.
I checked after i'd make a phonecall, hardware consumption for radio was on 99,9%. After reboot it was ok again, but later hardware consumption for the screen was at high level. Strange... everyday a new experience.

Turning LTE off helped my Spectrum last 24+ hours. I turn 4G on whenever I really need it, though. And with 4G on all day, I can get 12-16 hours under moderate use.

+1, better battery life than stock ROM

I have honestly never seen a phone go through battery quite like this one. I love the phone to death. It feels solid in the hand, and the screen quality is amazing. But I can't deal with the battery going like this. I input a new APN so it would just use HSPA+ .. but does that actually stop the LTE radio from searching? (I am in a non-LTE area)

I tried a trick to increase battery life by disabling a service called fast dormancy. read here for more information http://www.itcse.com/2012/10/increase-galaxy-ace-battery-life/

The most important thing which consuming the battery is the screen

Found this nifty program that is made for the LG phones. I will report back to let you know if I found it effective.

My experience with this phone is that ips screen battery usege is higher than lcd and amoled
amoled phones consume less battery because amoled hasnot edge to edge backlight and pixels have light themselves.

Yes our screens are a big consumer of power but there are plenty of disadvantages to AMOLED: heat, image burn (like a plasma tv), image quality and longevity of the screen. The more pixles that are lit the more power it uses, to the point that it uses more power than IPS with large areas of the screen are lit. This along with image retention is why CM7/9/10 has black as a background for everything and stock doesn't. Think of it as LED/LCD TV's vs Plasma. Similar power curves between them.
BTW the little program above dropped my idle power usage to only 5% over 8 hours. I will be trying it with cm10 to see if I get similar results.

[Q] Is this a bad battery?

I bought a used Galaxy S3 just a few days ago and have had pretty crappy battery life, or at least crappy when compared to what I read in some reviews. This guy claims that a 90 minute video with sync going on in background drained the battery to only 82%. I'm seeing much worse numbers. Leaving the screen on for one hour drained the battery to 75%. Other than occasionally touching the screen, I didn't use the phone for anything else during this time. Screen brightness was set to about 60% and wifi was off. The phone is rooted but still on stock UVLH2. Screenshots of the battery usage screen are attached. Does it sound like I have a bad battery?

Most people are getting about 5 hours of screen on time per battery charge.

At that rate you get 4 hours thats what I average with 2 different batteries.

But I'm not using the device for anything. There is nothing running. You can see in the screenshot that the only two things using the battery are the screen and the system process, which is at 2%. Is the number cited in the review I linked to in the original post simply BS?

I don't understand what you are trying to say. I left the screen on as a mean of draining the battery that can be easily and consistently reproduced. Browsing the web, playing a video, or running some app introduces additional variables that I can't easily control for. If, as dkmlb says, most people are getting about 5 hours of screen time while also using the phone (browsing the web, playing a game, etc.) and I'm getting only 4hrs while not using power for anything but the screen, then there is possibly something wrong with my battery.

you need to use the phone more for the battery to adjust itself. I set the brightness at 50, wifi on (when outside, 4G on), GPS on. My daily usage includes checking email, reading news on Pulse, check google play,etc yesterday the total screen time on was 3 hours. All of that last over a day (24h) and I still had 10%. (I dont play video, music, games, etc..)

What you said was true I didn't even think about it, but give it a couple days and cycle the battery normally (don't let it go past 3% with out plugging it in) and use it as a daily use and see if its good for you.

Battery life ...

Hey everyone,
My battery life is at 65% with only 3H "on battery" time.
The screen has used up 52% of my battery life -_-

Any advice.. this is a HUGE battery drain.. should i turn off Automatic and just set it to something lower?

Yeah, I had the opposite yesterday. Charged to full, screen on 50% brightness for 3+ hours, benchmarking, all sensors on, etc.
Today its still going strong. Bad battery maybe?

Damn! That looks impressive. Are you using the i9500 or the i9505? Also, what did you have enabled/disabled and how heavy were you using your device? It looks like you could last an entire 24 hours on one charge.

if someone can tell me the button combo to take a screenshot ill upload mine

I was shocked my battery lasted all day with wifi and bluetooth on. Something must be wrong with your unit. I am just now charging it - 14 hours later after HEAVY use of texting and internet all day today. I even use the face recognition to unlock the screen.

To cure your problem. ....
New device for first time comes to life doesn't have calibration set by OP system. .....
So first charge your phone to full and go beyond warning to charge and go down to 3-4 % remaining charge then plug to charge and charge without stopping to 100%
And do 2-3 times like this then your battery discharge will show properly
Also good habits are to use .....
Hold home button for 2-3 second and open little bottom screen click on bottom left and choose ram.....then clear ram....any time you going to idle and each time you going to charge. .....to find more about what this do search XDA .....
Also there is many hungry apps on market that runs under ground all the time. ....so learn and discover how to take control of your phone and make it run like champion
#2 you can use ES task manager to do some fine tuning to get the most juice of your battery
#3 Better battery stats
#4 Battery booster
#5 Juice defender. .....are some alternative to top of the iceberg on your solution. ....or you can take time and learn to do all this by yourself manually

Is everyone who posted on LTE or just hspa+, 2g etc?
I notice a big improvement ( like another person mentioned in another thread) when lte is off. My speedtest results between lte and hspa were the same download speeds but lte had better upload by two megabit.
battery life for me is great, then again im coming from an htc amaze lol. That battery suuuucked.
update
I did a few more tests w speed test.net and noticed that when on HSPA plus and not on LTE I actually get faster download speeds. On LTE it was 8 to 10 megabits the last 24 hours and now HSPA plus I'm getting 18 to 21 megabit down. Anyone know why this might be?
P.s. live in Manhattan NyC.

Depends when you do the test because more people may be on the network at certain times. But I thought lte wasnt launched in nyc yet...

I was considering picking one of these up if the battery was better than what I'm getting with the One but sadly this seems worse. I'd like to see more results before concluding that it's any worse.

you could be right.
the representative told me LTE was in New York City but as we know they know nothing... its still weird that when the phone is set to LTE auto he gets slower speeds than one connected on HSPA plus.

Bad Battery Backup??

Hi,
I have been getting only 20 hrs of battery and only 3 hours of screen on time. I have not used any processor intensive apps. Please check the images attached. Is this normal? I have bought it a week ago and I can get a replacement if the battery is defective. What do you think? Don't plan or rooting it.
P.S: I have chosen ogp over n5 because of the extra battery, but ogp's battery is equally bad.

Normal usage.
After playing 1hour of injustice i get around 3.30 of screen on time.
WiFi always on.

You need to understand that they provided the extra 'oomph' in the battery department, because this is a HUGE screen.
Another thing, is that LG's stock interface is filled with a lot of white menus, and submenus, etc.. That will also impact battery life more than you know.
Another factor to bring in to consideration is the cell coverage. Your phone has to work harder to acquire signal, in hard to reach places by your carrier.
All of these and more (wakelocks, no deep sleep, etc..) Have a big impact on your device's battery life.

[Q] Battery life with that display.

I am thinking of buying the G3, my only concern is the battery life.
Does the monster display's resolution affect the battery life much?
How much on average does it last and how much does the brightness affect the battery life.
Thank you!
PS. Sorry for my English :/

Search on Google, there are plenty of reviews covering battery life as well. Briefly, "surprisingly good" according to most of them.. not worse than competition (Z2, M8, S5) but not as good as its predecessor G2, means that it is good enough.

I have 100% auto brightness and am on 49% battery with 3 hours 1 minute screen on time. That's good.

All reviews are essentially saying that, despite the screen size, this phone basically outperforms everything else in the battery department.

So far I am getting between 11 and 26 hours with usually something in the middle 15-18 hours. This is on 85% brightness auto, wifi/bluetooth always on, location always on. 2+ hours of video playback and total of around 4.5 hours screen time in the battery stats

Just wait til custom ROMs drops.. The Battery life will be a killer.

Truth. Really depends on the bootloader situation. Fortunately, it's nice that the root is available--at least debloating the phones of preloaded junk can be done.

Its actually better than the S5's battery and my HTC Butterfly S 3200mah battery.
I can easily last 2 days using the LG G3

I had all three phones I would say the htc m8 is the best ,the g3 would be about 92% of the htc and the s5 would be 85% of the htc.
