Show us your battery life!

It seems as though battery life is one of the most common topics among us vibrant owners. We are always looking to increase battery life, whether it be with a new rom, new kernels, or apps from the market. I wanted to start this thread for everyone to share their experiences, tricks of the trade, etc on getting the best battery life.
Post pictures, rom info, kernel info, app info, modem info, battery info etc! No pic, no proof!!!
This is the best I have been able to get with my phone with:
Bionix 1.3.1 - Stock kernel - KB1 modem - TW launcher - auto brightness off, set about 2 clicks from the left - battery calibration app used at 100% - Stock battery. Light / Light moderate usage, phone calls, texts, web searches. GPS on.

Well, this is great battery life you got there For me 24h is the most I can squeeze from my Vibrant with Project V/Bullet 1.42 kernel, auto brightness off, moderate usage. 16h with heavy usage... It's fully charged now so I don't have pics to show it

i used around 5% with in an hour with somewhat heavy usage this is cm7 nightly 71 bali with uv

srdjav - have you tried bali uv? I heard it works really well, especially with bi-winning, but I have heard great things about it on all different types of roms

gamikzone - impressive for cm7, I have read horror stories that the battery life on it wasn't all that great...but I guess with the kernel script and bali, it's way better!

@corpsetomb
Yes, I did tried Bali... But honestly, didn't see much difference in battery life. I have tried 4 different kernel on Project V and battery life was always 16-24h, depends of the usage. With extremely heavy usage 16h... So i decided to stay with Bullet 1.42.
But I didn't try Bi-Winning ROM yet... Maybe I will give it a try
But I had very bad experience with Super_DragonMODz 1.5 kernel... For a few hours everything was ok. But in one moment I picked up a phone after doing nothing for a half an hour and it was HOT! And I could smell "burning" inside Luckily when I took battery out and let the phone cool down, it was ok

Can we see pictures not words :/

haha what is this, a courtroom?
truly, none of this matters. one big factor in battery life is application use. in order to pinpoint someones battery usage, one would have to list, in detail, their application usage. which/how many apps poll for background data/how often? is the person using an autokiller/ram optimizer? which/how many apps stay open in the background, even when killed?
The bottom line is, battery life is ultimately determined by the user. there are only so many differences, in terms of battery, between these roms and kernels. none of them will give you a SIGNIFICANT difference. this is not the fault of the devs, they are not magicians.
This is why people do not get nice responses in rom/kernel threads when they ask "how is the battery life?". Then some clown who is a very light user will say "its great! i get 20hrs per cycle!!" and then you flash it expecting ground-shaking results...only you forgot that you have 317 apps on your phone (20 of which are constantly poll/checking for background data), and you use your phone/data like a whore who youll never see again. and unfortunately, there are horrible noobs out in there who, after doing this, will actually go back into the thread and say something like "DO NOT FLASH, MY BATTERY DOESNT EVEN LAST 8 HRS!!!!"
Theres only one true way to REALLY compare battery between ROMs/kernels (and it still isnt 100%trustworthy): download a ROM, try it out for a few days at moderate usage. Then flash the one you want to compare it to. Make sure you have the SAME exact setup as the ROM before (apps, brightness, GPS on/off, background data, etc.), and try to mimmick your usage with the other one. NOW you can effectively determine, relatively, which ROM may show better battery results for everybody. and then, when someone asks "does this have good battery?" you dont just say yes; you say "yes, i have seen noticeable improvement since coming from _______ rom, i about ___hrs more per full charge "
sorry for the rant

Come on man, how did you menage this? Do you have any apps install on your phone?

@TopShelf10
No worries, I welcome your input! I agree that a big factor in battery life is application use. You will see in the OP that I recommended people put in as much detail as possible along with their picture, such as what type of use, kernel, rom, etc. I would also like to hear and see comparisons between roms, that is part of what this thread is all about! To be able to compare different roms and see what helps based on usage.
Thank you for participating and your input!
Note: Do you guys think I should start a list of best battery life in the op?

I know this but anyone can say I got 24hrs show me me proof

You can manipulate the battery use stats pretty easily... at least on CM7. If I plug my phone in to charge for an hour, it doesn't reset my battery usage. Sometimes when I look at it it will say 24 hours+. Which I know is not at all accurate.

Android 4.1.1 Jellybean Battery Life Thread

Seeing how a new firmware came out on the Nexus S, I want to see what kind of battery life everyone is getting on Android 4.1.1 Jellybean. And since everyone cares about battery drain one way or the other, we can use this thread to post tips on getting more battery life and/or try to figure out what's causing battery drain.
---
Anyway, PLEASE include these when showing your battery usage:
What ROM/kernel/Governor you're using
A combination of the three can determine why/how you're getting the battery life you're getting. Also, post thread link for the ROM/Kernel if you can.
SCREEN ON TIME
Probably the most important thing to know when determining battery life. Since the screen uses the most juice and generally the amount of time we'd be looking at our screen, the screen on time is very important to show. You can get this by going to Battery > Screen
YOUR GENERAL USAGE
How you used your phone is another important determining factor of how your battery was used. If you took pictures or listened to music, that would explain why you got such low battery life. More information the better.
IMAGES
Images help as it gives information which would be probably be too difficult to describe. The Battery section in the Setting section would help as would Battery monitoring apps
A simple template would be the following:
Code:
[B]*IMAGES[/B]
[B]ROM[/B] -
[B]KERNEL[/B] -
[B]GOVERNOR[/B] -
[B]GENERAL USAGE[/B]
blahblahblah
[B]CONCLUSION[/B]
blahblahblah
----
ADDITIONAL TIPS
- Show images of CPUSpy. May help see if your CPU is running out of whack or if, for some reason, is running on 1000MHz too much.
- BetterBatteryStats app screenshots. It gives a much better detail on what's waking up your phone, what apps are using it, and so on. You can buy it HERE. It's a very good app to monitor battery usage.
- More images the better. So we know what's going on with your phone.
PLEASE DONT
- Embed too many images to your post. It'll be too difficult to look at this thread with hundreds of images being embedded at the same time. Plus, people looking on mobile phones would probably struggle opening the page. If you have a lot of images, please just post the link and not an image
Anyway, thanks! Hopefully we can get amazing battery life on Jellybean!

ROM - Jellbean 4.1.1 OTA from here: http://goo.gl/AXr2d
KERNEL - Default/Stock kernel
GOVERNOR - Default/Stock
GENERAL USAGE
Usage was, in my opinion, light and didn't really do much. Most of the time, I was on 3G only to go on WiFi when in a Starbucks. I turned off my phone when watching The Dark Knight Rises and trying to save the most battery but that didn't really seem to help. I used the camera once in a while but didn't listen to any music.
CONCLUSION
So far, this battery seems kind of... bad. Especially with my usage (which I thought was light), I thought I could get more screen on time than just 2h 14m. I'm a tad disappointed and might go back to ICS just for the better battery life.

ROM: Unofficial CM10 by Lego
Lazy gov. Air kernel test 112.
The 2 hours of screen usage were from playing temple run, xda, and fb.

That's a good cycle IMO ^. Have you done a factory reset OP? Force of habit has me doing it anytime I do an update to avoid any issues. It also seems like you have a crappy signal at times. I haven't had a chance to actually judge battery life but mine seems to be on track to be about the same as it was as on ICS though.

It's weird because I'm using the same radio as on ICS and I seem to be getting worse signal on Jellybean? I might reflash a new JB ROM and try that instead.

I have a 2300mAh battery on stock JB i might upload some screenies later but i havent seen the battery life decrease it seems to be the same

Yeah. I'm gonna probably go back my KF1 radio once I update my ROM tonight.

IMO I always do a preliminary test the battery when the phone switch to airplane mode in a night, if the drain only 1% then the ROM is quite good.

Right? I miss the GB battery life, could leave GPS and 3g on all night, not touch it, and lose 2% in 10 hours. With ICS I was grateful if I could get it down to 1.5%-2% in an hour. And Google Now is too awesome to turn stuff off for, so JB is even worse

My battery life is absolutely horrible. I think my battery is bad though. I've had it since I got the phone. When the nexus came out.

Its one of those pay to play situations. My job has places for me to safely charge my phone so the battery isn't too big a deal for me. Best bet is to carry a spare charger. It is after all a pocket computer. Sucks, but until battery tech catches up, there isn't much us or many other smartphone users can do.

I think the background sync drains battery when idle. With sync on during idle, the batt drops ~3-6%/hr. If sync is turned off, it becomes ~1%/hr. (using 3G)

Exactly what Google things syncing would cause such a drain? I have this type of usage but all I have is Gmail syncing and I only get a few emails a day. I have obviously noticed increased life disabling Gmail, but how could it be using so much if it is push?

I'm getting, at least, the double than before...stock, unrooted

I don't understand this.....
The only thing using CPU is Android system at 5-15%... why is this happening? The screen was off for at least 8 minutes
Sent from my Nexus S using xda app-developers app

Since it just started up, and I'm guessing it is syncing like crazy. Calendar, instant upload if you have that in G+ or drop box chrome, contacts, drive, Gmail... Etc. Location is happening (maps, and latitude), checking for updates, weather. Check again in an hour and see if it has settled.
Sent from my Nexus S using xda premium

I havent noticed a problem with my battery. It's actually been pretty much the same. I go almost the entire day not charging it on normal use (almost 12 hrs). Heavy use with me is constantly playing games, I get maybe 3-5 hrs depending on screen brightness. It's pretty much the same as ICS for me

[Q] Disappointing Battery Life

I got a Nexus 4 yesterday, and so far it has been excellent. Really fast and has all the features I want. The battery life is pretty poor though. I am at 28% with a screen on time of only about 2 hours. The total time is about 8 hours. I haven't been using it a lot. The main thing consuming battery seems to be Nova Launcher for some reason. I have it on my Nexus 7 and it doesn't decrease battery life at all, but it seems to use a lot more on here. It was at 24% according to GSam Battery Monitor.
I just followed a bunch of instructions for increasing battery life from various websites so I will see how it goes. I now have all the Google syncing disabled, location services off and brightness on auto.
Is there anything I should be doing? Why is Nova Launcher's usage so high?
Thanks,
EDIT: Could it be the widgets I am using? I have two Gmail inbox widgets, the messaging widget and the circle battery widget.

Same here though I'm not sure its nova, my battery got as bad as yours when i rooted to stock.

it could, or any other apps you have working in the background. it can also be how you use the device. but before you assume anything about your battery life, give it 3-4 battery cycles before it normalizes.

Alright. I have minor OCD kind of thing so I always close the active apps through the task manager as soon as I exit them. I'll give it a few more days and then pursue the issue further.

im ocd about that too, lol. the back button to kill is one of my favorite custom rom features. also, autostarts and greenify are both great apps to make sure that you have mich less ctap opening in the background. anyways, im a heavy user normally, battery life on the nexus 4 id never call bad. usually i get 3.5-5.5 hours screen on time, depending on use. but then again, i use a custom kernel thats optimized for performance and battery. but, stock rom/kernel isnt bad on battery.

I too Force Close all the social networking apps before sleeping and turn wifi off. And i daily get around 4 hrs of OST. Will attach pics later to show. So to get 4 hrs OST you need really need to have a custom kernel. Just optimize your usage and you are fine with the stock kernel.
Phone is totally stock. Not rooted. And i got 6 pages on Apps installed.
I even used to clear RAM every now and then but I just stopped doing it as I couldn't find it doing anything better.

The battery life is much better now. Yesterday when I got back from school it was at 40% or so, and today it was at 68%.

Gets better after a few battery cycles. My battery life was average, so I rooted and with matr1x kernel it's snappier and better battery.

i'm stock and my battery life was shockingly bad on the default settings until yesterday when i tried some fixes and they have made things much better.
looking at my N4 right now, i'm still on 58% after 22 hours. that's after several voice calls, some browsing & reading emails, GPS navigation using Maps, a couple of skype video calls, wake-up alarms etc.
basic fixes as follows:
- screen brightness right down to maybe 10-15%
- data off when not being used, ditto location services
- NFC and BT off.
- i've left wifi on as it doesn't seem to take much battery if it's not being used.
that's all! after charging last night, i woke after 6 hours or so and was amazed to see it had dropped only 1-2%, so apparently nothing is waking it from sleep.

One thing that really improved my battery life (when I had a Nexus 4) and something I tell to anybody with poor battery life, is to go into maps, go to settings, location settings, and uncheck "report from this device". If you've got the app "wakelock detector" just watch the wakelocks from maps almost entirely disappear. It nearly doubled my battery life at the time.

Hey thx man that didn't work but it did start me down the path to fix my problem.
I found out it had something to do with my GPS options its in settings and location access WiFi and GPS location options i checked it off and now i am getting 1 hour screen on time for every %10 if you do the math i have about 8hours of screen on time! I also have setcpu app which is giving me about 48hours of standby time, i will upload some screens after a bit more testing.

My battery life is brill and i never turn owt off or force anything to close, it is only bad when i play a 3d game or something but what do you expect. over night it only drops about 1% every 4 hours which is a bit bonkers.

just do what people say, disable location useless stuff and monitor your wake locks.

If you would like to risk such things as unlocking bootloader, rooting, installing custom ROM and kernel, then it'd be easier for you.
Personally, I've found codefireX ROM and faux123 kernel to be battery friendly and very responsive, but of course you've got to be a bit fixed on such things as playing with your devices and getting fun from it to do that

[Q] short battery life s4

I takes about 10 hours, the lesson download much battery? when I go to sleep I lose almost 15% of battery. Any solution?: (

Battery life is terrible.
I refuse to do what my friend does:
Turn vibrate off
Turn screen brightness to lowest
Phone is always connected to Edge - unless he's using the Internet - then he switches back to Edge
Syncs his email every 15 minutes (pull not push!!!)
Always 'freeing ram' and exiting apps
His life sucks.
I am the opposite. Full brightness, 4g , push mail for my 4 emails, exchange server (email and calendar) for work and so on.
I manage this by always having a spare battery that I charge with my battery charger dock lol.
Will be doing the same thing once I can get one for my S4

I know, so far it's been below expectations for me too - I ordered a portable energy bank from Amazon this morning, and I guess I'll just carry it around with me from now on.. What a shame - the phone is extremely powerful too..

Install gsam battery monitor and let it monitor your phone and see what is causing wake locks. Also let the battery go through 3-4 battery cycles before you start comparing battery life.

That'd weird. Isn't the 9500 or the 9505?
My battery exceeds my expectations by quite a lot. Best battery I've had on a smartphone so far, and I've had a few.
Where my 920 died, this one still has 50-70% remaning.

I am also curous how many hours does it take for the battery to reach 15% and how much screen on time do you get. Please post a few screenshots!

After a day i have like 30% left. Screen on time is about 2h.

I get similar battery life as well. Sometimes 4 ton6 hours screen times
16 hour days
I found my battery life improved when I got rid of a poor quality 32gig media card and used another spare old16gig one.
I also dumped corrupted mp3 files and videos and got new ones.
I think poor sd card quality and bad mp3 files are partially responsible for lower battery life.

So far with battery saving on it seems that nothing changed... Will test it further with daily use. But battery life here, even before using the app was not bad by any means.

I get similar battery life as well. Sometimes 4 ton6 hours screen times
16 hour days
I found my battery life improved when I got rid of a poor quality 32gig media card and used another spare old16gig one.
I also dumped corrupted mp3 files and videos and got new ones.
I think poor sd card quality and bad mp3 files are partially responsible for lower battery life.

Yep. I'm really impressed with this phone s battery life, not too far from the note 2 battery life but not quite there.

S4 Charges fast and Discharges fast

Hello,
My S4 is nearly a week old now, it's the international GT-I9500 octa-core version. Since it dons a big battery of 2,600 mAH (middle point of S3 and Note 2) it was suppose to last long more even with heavy usage.
My usage is moderate, a few calls, but I use connectivity extensively i.e. WiFi indoors and Mobile Data outdoors.
I tried switching off the WiFi to preserve battery and to see any boost but zilch.
Whenever I put the phone on charge, it charges very quickly and when the charging is complete and I remove the phone from the charger, it discharges pretty quickly, goes to 99% in a minute WITHOUT any usage.
What could be the issue? I even formatted my memory card from S4 as I read some bad mp3 files or something can cause the battery drain and such.
Everything is stock, both ROM and Kernel and the phone is not rooted atm
I'm attaching the screenshots for my cycle with minimal WiFi and Data usage.

Tried power saving, no improvement.
Brightness is already kept at Auto with the throttle set to 0.

I can get more than 16hours on my S2 easily with average usage...This is just BS optimization from Samsung...

It's better than the s3 because the battery is larger but I'm telling you that screen is a hog. It's larger and brighter and its 1080p; yes the resolution causes the gpu to eat more battery too.

I freaking hate watching my battery drop.. and mine goes by quite quick. . I have wifi and mobile data on.. When I leave my house I toggle off wifi. I read that having mobile data on all the time doesn't use battery. . Is that true?
Anyway. .I just turn off the battery percent.. Can't stand putting the phone to sleep at 80 and turning it back on 20 min later at 75.

im wondering if there's a way to switch the screen to 720 mode instead of 1080p to save battery life. similar to switching a computer monitor so you stress the gpu less during a game... this would also save a small percentage of battery life...
also a more efficient auto-brightness would be great.

Same here, hate watching the battery drop so soon. For me, what I've observed is that WiFi eats a lot of battery than mobile DATA for this set when it should be the other way around...
I have my internet disconnected at home due to some upgrading of the lines in my area so I haven't been using WiFi at home, only at office, so mobile DATA was switched on all day yesterday at home and when I go outside and surprisingly the battery didn't drain a lot.
I'll post screenshots of this cycle as soon as the battery drains down to 2%

No! Mobile data is one of the biggest battery killers going! I have my toggle within the first 5 so I can turn it on and off when I need it easily

With big screen and higher resolution, it will definitely consume more power. try to turn off screen and kill running apps when not needed.

16hours on battery is quite good considering the WIFI indoor and Data on.
i probably get a little bit more than that but less wifi usage and data is only EDGE in my country.

Nothing alarming
Firstly, your stats are perfectly normal. I got the same results on my stock octa core version.
Try omega its much better battery consumption wise. Other tips: Switch to 2g only if you are using your phone just for chatting, keep backups off and turn unnecessary sync off. Turn off your screen tap sounds.
You might already know all this.
Anyhow, trust me 16hours at 60% is not bad. Hopefully samsung will do something about it with future updates.
CHEERS.
Ow and if you are over with your honeymoon with all the air motion gestures smart eye tracking features, turn them off if you want to save some more.
