AOKP + Latest Franco Kernel

Thanks. So far I've had my best with eagles blood and stock kernel. I've heard Franco's kernel has bad battery life though?

Sounds like an easy thing for you to test, doesn't it? Sorry to be snippy, but this is one of many similar threads. No one searches anymore, and there are many threads like this which have "it depends" as the only logical answer.

OS: 15%
Phone inactive: 12%
Voicecall: 9%
Mobile rest: 6%

Mediaserver: 4%
Now i havent used it alot, turn of everything i can, when screen of running on 2g only and such, i havent used it alot, listen to music for totaly 1h 30m. No surfing and such.
What roms and kernels have you used and what have you gotten out of it?
What extra apps maybe taskkillers and such do you use or think is good to get more battery?

Bad battery life? Do some searching and read his kernel thread. Battery life has been amazing with his past releases. Build 7.1 are heavily exceptional builds.
Anything before that, yes the battery life hasn't been so good. But now his focus shifted onto the battery. Many people included screenshots of their battery graph.
Aokp also has a power saver mode, read into that as well

I did run AOKP build 12 for 1 day, and thats how long my battry lastet with nearly no usage at all. The same with eaglyblood all on latest fran kernel, with juicedefender ultimate on agressive setting.
So how can i test and post graphs for you?
What baseband are you on?
Is there any good taskiller i can use?
Dont know what is using so much battery except the screen and i have it on very low always.

I use stock 4.0.2, non rooted or unlocked bootoader, and I find the battery life better than most android phones i've used previously. However, occasionally, it gets low, then i plug it in, and later it's charged again!! As if by magic!! Also i noticed that if i turn it off completely, the battery life is aammmmaaaazzziinnngggg!!! *palms face*
sorry, these battery life threads really get my goat! On a serious note though, one nugget of knowedge that I have taken from messing with android for years is, that if you, like me in the past, have been one of these types that just cannot stop flashing roms left and right, then you will never get to see the full potential of your battery. It does depend of course more on individual usage than anything else, but, settling on a rom of choice and using it normally over the course of a week or so will see you gain an increase in capacity thereafter, just through simple calibration.

Im running AOKP v.13 with Franco's Kernel 9.2 and battery is really great, even on heavy usage. There's almost no batter drain in Sleep Mode (last night ~8 hours, the battery just dropped for 2%).
I've set up my syncs, set up AOKP's Powersave Mode to my wishes and made a ScreenOff Profile for franco's Kernel. That's all, and im still on my second battery loading cycle. Cant wait to see what will happen if it's callibrated well.
With AOKP Rom and its Powersave Mode, you dont even need Juice Defender anymore, its doing nearly the same.

Thank you, i will go back to AOKP in a few days and try build 13, i update you all
My battery holds 1 day 24hours, would say normal use with 2g on when screen of, 3g when screen on, i dont surf on it check facebook maybe 2 times on it, nothing more, text sms and few calls lasting maybe 40min total

How is your standby drain with that setup? 1% per hour? Or less?

Battery life with Jellybean

I know it's still early but has anyone else found Jellybean to have worse battery life compared to ICS? I'm totally stock with only the bootloader unlocked. Usually after a full day use with ICS I have 30% left and with JB I'm around 15%. On a day with heavy use I'm sure I will have to charge in the middle of the day which is very inconvenient. I'm trying to see if it's JB itself or some app which is draining things now that I'm on JB.

I'm finding it to be significantly better actually. I couldn't make it through a full day on ICS most days. With JB i'm easily above 30% most days at end of the day.

Maybe its because you like more your phone now and therefore you spend more time playing with it

Mine seems worse compared to 4.0, phone doesn't go to deep sleep and keeps waking up ... maybe it's my Exchange email account, but this was fine when I was on 4.0.
How is your phone sleeping?

This may seem a strange suggestion, but I've found that leaving wi-fi on, even when I'm not using a wi-fi network seems to even out the battery drain. Helps to get Google Now working 100% as well. So try that when you can. I've found it works fantastically for me.

Stock vs. stock ROMs (both using LeanKernel as well) I've found Jellybean to actually have better battery life. I managed four hours of screen on time with the stock battery yesterday and today, something I could never come close to accomplishing with stock ICS.

turn off wifi, gps and 3g, and you'll go far. Turn em on only when necessary. I leave google now on. I'm only at 40% after 22 hours. Granted it defeats the purpose of a smartphone, but if I'm at work, working...then I don't need all those things turned on.

Turn off Google now of you don't really use it. I loved playing with it for a few days and realized it wasn't THAT useful for me I only really used weather. I keep the voice search active and turned the cards off. I just use a decent weather widget and maps WHEN I'm travelling if worried about time. HUGE battery saving. So many (understandable) wakelocks when activated.

It's weird, it seems the battery life is worse, but it could be that I'm using it more than before. The on-screen time does seems slightly better than on ICS, but I'm going to need more testing before I can confirm...

Hmmm...I will try that out, thanks. Google now was fun to play with the first couple days but if it means I need to charge middle of the day forget it. I will try turning it off and see what kind of results I get.
For the record, I've left all my GPS, Wifi and sleep settings intact from ICS so those settings shouldn't have effected my battery life.

I don't care for Google Now, just the new voice search part.

I could be wrong but I think project butter requires the processor to run at a higher clip and thus uses more juice.

I'm actually getting better battery life on Jelly Bean than I was on Ice Cream Sandwich. Running at a higher clock isn't the only thing (or the main thing, I think) that gives Jelly Bean it's buttery smoothness.
Google really put effort into improving Vsync on the device, which mainly gives the device that buttery feel.

Best ROM for Battery and Data Use?

I am sure this has been asked, but I really need some help with this. I am using fully 4.1.1 STOCK and I do use the data on my phone quite a bit, but I don't see how after 6 hours, my phone is completely dead after a full charge. Screen on time was roughly an hour and a half! What is the BEST ROM with the best Kernel even, for battery life and extensive use of data?

The max I could get waas 2 hours screen on time, 3G really hurts your battery, I don'think theres anything that can change that

stock is always best.

Really? Damn. Well, I turned off all the Location services as well as set the brightness to the lowest possible setting. Guess I'll see how that works. But really, that sucks. I wasn't even on it that much, only a few hours

No I don't think so. Are you using the Verizon or GSM version. There must be something with your phone or the settings, possibly a wake lock issue. With the GSM version and 2000mAh battery I can pull 3-4 hours of on screen time, using roms like AOKP and Franco Kernel. I turn off data, wifi, gps and bluetooth until I need them.
Can you go into Settings -> Battery an take a screenshot. Then press on the "battery graph" to reveal the history details screen and take another screenshot.
Not sure if it work with stock, but holding the Power + Volume down button should take a screenshot.

Every bodies phone acts different with certain ROM and kernel combinations I have had good luck with lean kernel but that doesn't neccassarily mean you will
Sent from my Galaxy Nexus using Xparent ICS Tapatalk 2

For your display brightness, you may want to install Screen Filter. Its in the market. Especially without having to tinker with the display settings it lets you dim it down even lower than the lowest setting. Also great for movie viewing in a low/no light setting.
I think this requires root, but you should try Better Battery Stats, select partial wake locks since charged, and see what the culprit is.
CPU spy would also be a good one to see what frequencies your cpu is running on the most.
I'm currently on liquid beta 1. It seems to hold battery quite well compared to cm10. I also use trinity kernel, and the TKT app.

[VZW] Galaxy Nexus - Battery Life suggestions

I have a VZW Galaxy Nexus and I am trying to improve the battery life on the device. I really don't do much with it other then texting and some FB/email here and there during the day. When I am driving back and forth to work I use the device to stream my music or run Pandora.
The battery life during the drive is not the huge issue, I know that using LTE and streaming data is going to use battery quite a bit, but when my phone is still with Wifi off at the office and I may send like 5 texts the device can drop 20% in 10% in an hour.
I am using Winner00 - CM10 rom right now with the kernel. I am about to try AOKP Build 3 but wanted to get any idea of what others were using and their battery life results. I am running the stock battery in the device.
Battery life and Stability is the most important things to me. Running the phone at stock GPU and CPU speeds is fine for everything I do.

There are some things you can do to improve but nothing that's really going to be a game changer. Buy a few extra chargers. There are a plethora of battery threads already, use the search function.

Get a giant 3800 battery like I did. It's ugly but I get over 5 hours screen on time and a day of use
Sent from my Galaxy Nexus using xda premium

You should give lean kernel a try. I'm a heavy user on aokp b3 and always on 4g. Since using that setup I've seen improved battery. Every kernel is different but lean kernel seems to have consistent performance.

Dude, get AOKP build 3. It is really good with battery life and also, it is extremely smooth. Although, I do recommend using Franco's Kernel in combination with this ROM to get maximum satisfaction. I get around 3 hours of screen time, with 4G and WiFi in there. And also I have stock battery. Now thats saying something.

[Q] What are you currently doing to increase battery life?

We all know our GS2 runs out of Battery at a faster rate than what we would like! I'm just curious, what steps do You take to increase battery life, if any.
-Do you use certain apps?
-Do you enable/disable certain things and certain times?
-Anything, ever the smallest things you do, I would like to know!
I'm just curious to see what different people do to strengthen their battery.
(Also, if you could, please just post what ROM you're running on too) Thanks!

Battery Life
Im running FK23 leaked rooted with stock kernel. I use powersave mode that comes in stock settings app.
I don't limit cpu. I use phone to txt, play games, youtube, facebook, twitter, and instagram and google play store.
I get around 14+ hours usage.
Also, I try to use WIFI whenever I can. I turn off GPS when not needed. I dont use 4G often as 3G is pretty good on FK23.
Lasts me from 7:45AM to 10:27PM as of now on 1%.

Wow, and how much do you use you're phone throughout the day? I'm just looking for new ideas because I do several things to increase my battery length, but I find myself around 50% in the first 2-3 hours of my 11 hour day. :/

I bought a cheap ($10) extended battery and cover, and a cheap ($9) TPU case/ At 14 hours, I still had 61% battery left. I can get a full legitimate day out of it running 2.3's, but I am going to try JB and ICS again and see where it's at.

I run KingKang with the JB tweaks package. I also modified my build.prop for both performance and battery life. Plus I toggle my 3G on only when I need it. If I have a WiFi signal I'll do the same with that. I average 17 hours but sometimes I get more than 24. Inverted apps not only look great, but help with battery too.

I switched back to Calkulin 3.0. Battery issues solved.
I tried to make ICS work for a couple months, but grew to hate the phone. It's a much better phone when it runs Gingerbread.

I did the same as you until the fk23 leak came out. Calkulin's v3.0 gb is amazing for battery life, smoothness, and functionality. I was never fully satisfied with any of the ics solutions, stock or custom.
Although the fk23 battery life isnt as good as calkulin, I'm still using it as my daily driver bc it's jellybean and cool, the phone runs well and smooth, and battery is good enough for me.
To answer the op's question, I do the following to help extend my battery life:
1. Leave off all data unless I need to use it (3g, 4g, wifi).
2. Turn of autosync and only sync as needed.
3. Remove bloatware and/or freeze any unnecessary apps (use GSM battery and OS monitor to find battery hog apps).
4. Leave off GPS unless needed.
5. Set screen brightness lower.

Here's a link to my FK23 results over in the battery thread in General:
http://forum.xda-developers.com/showpost.php?p=34924972&postcount=534
I've only owned this phone since after the ICS update, so never tried any GB ROM.
The ICS ROM I've had the most success with is Re-Calked, but FK23 takes it just a step further for me. I know some people have been reporting issues with FK23, but for me it has been rock solid and has been my DD for nearly a week now.
Blu Kuban also did well with battery life, but it is a little over-customized for my liking. I also had some stability issues with BK. I used sleshpics M'ICS build for a while too ... again, over customized for my liking. Good performance and relatively stable. Also, I have never been able to get 4G speeds on any other ROM/kernel like I'm seeing now.
If I'm in an area with a strong cellular signal, I can get over 24h with 3h+ screen time both on and off WiFi. If the cell signal is week, I burn from 5-7%/h so maybe 15-16h if I was there all day ... but that would obv. improve if I threw it into airplane mode.
I have frozen all of the bloatware apps, don't have Google Now activated. Other than that, I allow syncing to occur per default. I don't have FB app installed.
I use auto-brightness most of the time, and I have a dark wallpaper.

dim screen. stay on wifi. that is all.

Honestly, getting use to a dimmed screen made a HUGE difference!!

Is there ever a time when its better to not be on WiFi, of a WiFi is available?
