How to improve battery life?

Hello fellas. I am running Fasty VI, and battery life has not been as good as I feel it should be. I'm aware that KH3 is one of the best fw as far as battery life goes. I also have turned off auto brightness, auto rotate.
Just to give an example, I took the phone off a/c at 6:30 am, and the time of this post at 8:56 am I have 69% battery.
Is it possible to increase battery life by using a different modem?

Whats using your battery? Check if a app is eating your juice. How many apps/ widgets you got running at once, are you OC/OV?

didnt realize there was a kernel with oc/uv for kh3
yes a different modem could help battery life, just make sure its an I897 modem and not an I9000.
also turn OFF power saving mode in display settings could save some ( i know weird but it helps adjust the brightness and when you have auto brightness off its just a meaningless process going on)
you could also switch to 2g when you dont need the speed, also turning off background data will save some juice.

Best way to extend your battery life is to get an extended battery
sry couldn't resist

Lol fuloplori.
I have power saving mode off as well I forgot to mention that.
As far as widgets go, today, which is what I've been using as ab benchmark, I have three minimal text widgets for time, date and battery, as well as evernote and keep the lights on.

No there isn't a kernel but there is an app that DOES OC/UV and OV the captivate. Its called Tegrak. Just saying....

Also I've had a issue with Maps app and when ever I set alarms battery drains alot faster. Not as much as you are experiencing but still. Random question have you recalibrated your battery lately? As studa said Modem might be the culprit bur I've never heard of KH3, KF1 or KI2 modems be a issue with native roms.

Well, I re-calibrated my battery a few days ago, but now that you mention it, I have doubts wether I should do it when the battery is at 100% or 0%.
Sent from my SAMSUNG-SGH-I897 using XDA App

Personally I charge it up to 100 then unplug and charge till it says 100%. I repeat that 2-3 times then I delete the battery file on cwm and let it drain till it shuts off. I've read of other methods no clue on differences. Btw Where you from bro?

I checked battery statistics and facebook was unusually high, at 24% right above 23% for display. When I checked on the market under my apps, out want there. I installed out and re-downloaded it.
I'll try your method for calibration.
I'm from Guaynabo, you?

That's kinda high. I recommend running the widget for facebook and only using the app for specifics, else keep it closed.
I study in Mayaguez.

Don't use your phone.

@ BenKranged - Good1
I'd suggest u get Watchdog Task Manager and track down the app/s that is/are misbehaving. For further more enhancements u could freeze cpl apps that u don't use/need with TiBu. Read more about it over on pikachu01's thread, keep in mind that his thread is i9k centric.
Last but not least, I hope ur not using a task killer !!! (specially on a regular basis)

As far as task killers I'm aware that they are not necessary anymore. The odd thing is that today, after unplugging my phone for 3 hours my phone is still @ 100%.

Task killer isn't needed. Android task manager does the job well enough. Task killer will just use more resources.

Use titanium backup and freeze apps that take up a lot of resources when they aren't in use.

Why I think battery life sucks so bad...

I usually have a multimeter on my counter for my ecig mods, and, since I change batteries pretty often now that I have spares for my thrill, I'be been randomly checking thier voltages. What I've found is that a "dead" battery is at ~3.7V. That's not dead. These phones should discharge to something like 3.2V. Anyone have any idea as to why they would read nominal voltage as dead?
Sent from my LG-P925 using XDA App

After few more charges, it discharges to about 3.43V, still high I think, so I'll keep an eye on it.

What you're saying actually makes sense. The system has to calibrate itself to the battery. This is why battery life tends to improve over time as you discharge and charge the phone. There are ways to kick start the process but eventually it will do it on it's own. My battery life has tripled after a couple weeks.

i am wondering why i have fully charged and discharged my phone numerous times and my battert is horrible. its gotten worse. i unplug it with 100% at 5:30 a.m. its now 9:40 a.m. and im at 62%! i have sent 2 text messages this morning and my app manager has no open apps. Why would my battery be so bad? i have had this phone since the day it came out and love it. im not real familiar with all the "rooting" or all this fancy stuff but i do know that the phone should have a better battery life than it does.
Does anyone know what i should be looking at to see what is killing the battery so fast. almost 40% in 4 hras and i havent even used it?
thanks.

Try installing a ROM that removes some of the services that a stock rom has this way will save your battery time a lot

I have installed several ROMS i am new to the LG Thrill but with my previous HTC G2 y used cyanogen but as per this is a 3D phone cyanogen is not ready yet. But the best rom i have tried so far has been the thriller
http://forum.xda-developers.com/showthread.php?t=1261704
although is missing good things from the newer firmwares like the 3d app converter.
But i'm ussing the thriller Rom until LG releases the Gingerbread official update that comes with great new stuff

Here's what I've found out about the battery. It's apparently a known issue by google addressed in later updates.
Here's a great method to work with it for now.

This mine with 48% battery life left. I found out on mine if you play one of the 3d games and don't exit out of right it continued to run and eat the battery. I use wifi where ever it is available. Always leave it on unless I am on the road then I turn it off so it won't be hunting for a connection. Have gone 28 hours and have 30% battery left.
Had phone since September 4th and battery life has improved tremendously. Stock and unrooted.

My phone is stock and unrooted as well. i charged it this morning from completly dead. started to charge at 6:30 am and took untill almost 11:00 before it was a 100%. now it is 1:30 pm i have sent 1 text message and thats it except meybe waking it up to see if i have missed calls or txt and my battery is down to 44%! 2 hrs really? i have not used it. Wifi is on but should not be sucking that much juice. i trashed the yahoo news app. my weather app is set to update manually. i dont have anything special done to my ohone like all these forums suggest the "rooting" or special rom's. it pretty stock.
I have used the battery calibrator app and it didnt seem to do anything for me. anybody else have other suggestions? i basically get about 3-4 hrs of battery life berfore having to charge unless i use the phone then i get about 2.
oh yeah and my wife has the same phone, some battery issues but i think her's is normal. so to see if it was the battery or my phone we swapped batteries. my original is in her phone working fine and i have her's and still crappy so i know it wasnt just a bad battery.
what do i do next??

You could install CPU spy from the market and see what it is showing you. See if it ever gets into deep sleep mode. I also use battery monitor widget from the market to see what all is using battery.

4.2 Insane Battery Life! Project Roadrunner?

I don't know if it's just me, but I've been experiencing some insane battery life of my N7. I've gone about 4hrs on battery, wifi on, and battery hasn't dropped even 1%. Anyone experiencing the same?
Flashed 4.2 factory image.

Without a doubt. Before 4.2, my screen on time topped out at 5 hours. Now I can pull 6 hours.

Sounds off. No change at all in 4 hours? Can't be correct.

There is no way that's accurate... Power down the device and power it back on. See if it still says 100%.

YES I am having insane battery life as well. Still 100% and hasnt changed after 3-4 hours. Will keep observing

I noticed the longer battery life also. When a lot of stuff is running sometimes I will use the ES Taskmanager Kill app and when I did that there is more free memory than before and even when a lot of apps are being used there is more free memory than before also.

HOLY. Definitely inaccurate. I notice a small increase in battery life, but nothing that big. I get like 30 minutes extra.

Ok.. Just powered down and powered back up..
Nothing changed.
I won't plugged my n7 til it dies.. See how long it'll last..

It's not strange on a devices with such a big battery to last 4 hours on 100%. Notice how the screen is rarely on?

That seems inaccurate but battery life is definitely better

That's what I was thinking. But since I bought the device, it hasn't done this. This is either a bug or battery life is extremely increased!
On 4.1.2 my battery drops 1% in 16 minutes of the same usage. This is definitely way beyond!
Still monitoring it.
Might as well play a few games to see what happens.

There is definetely a bug with battery readings.. It is likely drop more than normal , once it drops to %99.

Ok. I did a bit of NFS and it brought my battery down to 95%. Now to see if it'll drop normally.

...

I think your battery stats are jammed, I'm not seeing anything like that at best 30 - 40 minutes of extra battery, which is still nice. If your right your device is drawing power from the air around it

I had very simalar resdultsvwhen i flashed the ota url. But i flashed the factyory image the other day to start off fresh and no longer have reults like this. I'm not saying I'm getting bad battery... Far from it. It's just not the same as when i flashed the ota which is strange.

My guess is the update just messed up the battery app like it did everything else.Keep your charger handy so when your tab shuts down and it still shows 100% you can charge it.

Terrible battery life

Ive had the note since a day before launch and i havent been able to get more than three hours screen time out of it on auto brightness and simply texting or web browsing. It also has a lot of performance issues i cant figure out. Like severe animation lag when sending a hangout message, or huge keyboard typing delays.
Ive factory reset several times, and there arent any wakelocls. Standby time is great actually.

Same I've tried root and xposed everything still not getting anything more then 2 hours on screen time. Even at home when I have perfect signal.

I've actually had good battery life with stock rom. But seems to have gone down a bit with custom rom a bit. Could be random

Simply saying you have a bad battery life without itentifying if you are rooted or not, without providing any information about your battery, without showing your wakelock is rather...not a good way to acquire help.
P.S simply rooting and installing xpose will not give you battery life

That's actually what i ended up doing. Too early to tell, but I'm at an hour screen time (mostly hangouts, web browsing, email) and at 72% battery. Hasn't seemed to help performance much. I have 5 pages of apps including all the stock stuff. I lost 10% battery listening to an audible book for an hour too which seems high.

My issue is charging via pc USB port. with stock rim it would charge fine full charge as normal and the same with note 3 I had custom rom and with stock no issue. But with custom rom same thing running same apps and only playing Google music on the background the battery doesn't charge as well as it did. Not sure if there is any tips out there about that but as mentioned the only difference is that this is a note 4 the others note 3 and even on this for stock rom battery charges well with USB pc output. This is normally at work while sitting down on my desk and connected to my pc. While listening to music on headphones.
Sent from my SM-N910T using XDA Premium 4 mobile app

Mine did the same, it actually lost more power than it could charge, it went away, I'm not sure what I did, but now it's just as good as my note 3

Thanks for the input I don't want to go back to stock since these roms are just to smooth running on skyfall now. I'll likely wait and test it out for a few more days. But mine currently does trickle charge but so slow. My worry is long trips. But overall battery life is good.

Yesterday I got 4 hours screen time with 10% left. Android OS taking up the vast amount of the battery. That is decent, but I was really expecting more in the 5-6 hour area, especially considering my light usage model. I dont play games, or watch videos on it.

Android system highest battery usage help me find the problem?

As the title states I'm having an issue which a lot of people have generally and some find fixes others don't, I've looked around tried a few things but none seems to solve the problem! Now I'm running the latest version of Rapture ultimate variant on 5.0.1, the first night after installing this rom I was at 100% didn't charge once throughout the whole day, screen was #1 on battery drainage, had a decent SOT of 6 hours and 30 minutes I believe that's good but you tell me [emoji14], anyways the following days it's been android system with an average of 24% it's really starting to annoy me as its brought down my screen time a bit here's some pics of my states an what's android system running, I have several things frozen as well that are listed why there listed idk but several are frozen! If you know of any fixes to solve android system from being such a high usage please let me know! Thanks!

Stock battery app doesn't provide enough information to solve the problem. Apps such as Wakelock Detector are needed to drill down to meaningful information. There are also lots of existing threads that provide great instructions on how to improve battery life.

Somewhere within this list one of them was causing android system to be high which one for I'm not sure of but try the list give it a good 2 days or so from 100% to 0% battery and if it worked then I'm glad if not unfortunately you should try some other things, also try wake lock detector(root required) as the other poster stated as well as better battery stats (cost money and requires root)

I think I have it pinned down.
I am fairly certain it's caused by ims settings, ims logger, or ims service. I noticed none of these were disabled in your list, so I'm curious If u had improvement.

It's going absolutely great here's an example of how my battery had been since I did that list
as for ims service and the others that's for instant message service so if you text it would affect your texting an to my understanding would force crash whenever you try to text now I haven't disabled it but I'll go ahead an do that for you an let you know if I am still able to text people or not

Okay I disabled all the ims services as listed here
I sent several text they were a success I also tested Facebook messenger it was also a success as always I suggest making a nandroid but yes so far I have no force closes or anything now I just did it so I'll leave them frozen an report back in a few hours to let you know if I had any problems best of luck!
