What is the best kernel battery wise. I Just recently updated top one of the cm 10.1 rooms and the battery Is mediocre at best

Well if you look around, this device only has one kernel, that all 4.x.x Roms use. Hashcodes. He has done a lo of work in making it. You should think him and not complain about the battery life. And for a tablet I get a good 8 hours of continuous use with wifi always on. That's pretty good, if you want to save battery, try a battery saving app from the play store. Those seem to help people, and turn off wifi when your not using it

The recent changes Hash made to the 3.0.x kernel is now comparable in battery consumption to IR's tweaked CM7 kernal. With the right settings, I can achieve only 10% battery drain per hour of continual use.....which is great for an aging tablet

Rom with best battery life

Alright guys, whats your opinion: which rom has the best battery life?

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.

I have been using Francos kernel, and the new baseband, with both KANG and eaglyblood, i hav ejuicedfender installed on aggrasive, but i still cant get out much from the phone, i have right now on eaglybloods latest 1.5.
Running for 22h 4min
Screen on low: 39%
OS: 15%
Phone inactive: 12%
Voicecall: 9%
Mobile rest: 6%
Android system: 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

Battery life poor except for stock

I give up.every ROM I run just doesn't have the battery life expected. Am I expecting to much? Not even Cauks or blazer el29 doesn't give the battery life as stock.don't get me wrong they are all great roms but at least for my device not battery friendly. I'll post some battery stats from BBS if anybody has some free time to see what's going on. I'm on Cauks el29 now.I format everything before flashing and I use cauks format all many times. I'm on the verge of staying on stock roll my eyes.

Well when is the last time you used stock? And if it's been quite a while...consider having your battery checked out. Anyway, I'll continue as if your battery is fine from here on out. Basically, anything but stock tends to have a modified kernel. Even with all the battery tweaks, etc out there, there's a chance that the kernel itself might not play well with your phone. I'm not too versed in that, but I also noticed that the TouchWiz based ICS kernels/ROMs give MUCH better battery life than AOSP based kernels/ROMs such as CM9 and AOKP, etc. This is just basic stuff you might already know, but yeah, just go on and post your battery stats, preferably with a custom rom and a stock rom so we can see the difference and where it lies. Also, I'm running Touched by a Galaxy S3 on my phone and with moderate use (music for maybe a few hours a day, texting, don't really make many calls) I average between 8.5 and 11 hours from 100 to 0. Another thing I'd suggest is download CPU Spy from the Android market, or something similar if you prefer, and post screenshots from that on the custom ROM; the problem with AOSP and certain other GB and TW ICS roms that i've seen is that something prevents the processor from going into deep sleep mode, usually keeping it at 200mhz or higher. Lastly, when you use the custom roms, do you notice the phone getting really hot compared to the stock roms?
I'm assuming you know this but are you letting the battery cycle a few times before passing judgement? I usually spend a week on a rom before I decide if I have good/bad battery life... attached screenie is normal for me with moderate use on mijjhs goodness rom

I always had faster battery drains on ROMs than stock. I see all this awesome battery stats screenshots but noticed they all share one common factor, only 1hrs to 30min screen use. Come on guys why I would want that battery life if to get it I have to barely use the phone makes no sense to me.

Agree, everyone have different experiences, I haven't try that ROM yet, I will test it out later. Have a nice day/night sir.
Sadly I have to agree with OP.
And the previous screenshots at 59% with 1hr, 36 screen on is exactly the issue.
Hard to compare your battery stats with mine since screen on time for my phone will be 4+ hours.
Since there are no standardized testing anyone can do with any rom, any speculation on which rom has better battery life or doesn't is just pure bogus seat of the pants gut feelings.
If there were a standard test that ran like. 5 minutes of mail with 20 mails received, 10 minutes download, 30 mins of playing the exact same video, 13 music tracks of the exact same song all with screen, vibration, brightness, etc all at the exact same level, you could get a real test, but, alas, nobody has a standardized test.
For MY usage, stock clocks in at the same as or better than just about any other rom I've tried, including all the various super scripts out there.
I guess I just overuse my phone!

Things drain battery. This is my test off wifi for the most part using the phone as a phone with average use. Didn't even log in to Google on this one. Just proof that intensive applications, google services, and anything else added after a "factory flash" can manipulate battery life significantly.
Oh, and check out drain when I'm in less than ideal coverage. Noticeable difference. One huge factor to consider when diagnosing battery life.
It really depends on what you're doing with the phone. Obviously having brightness up playing heavy games with Wimax on will kill battery faster than someone on low brightness reading an ebook with wifi on. That said, i agree that I've had better battery life stock than almost all ics roms.

JB rom with best battery life?

Hey guys,
I am currently using Jandycane ROM and i think the battery life can be better. I sa "can" since i never used the kindle with stock. I just took and rooted instantly. Can you tell me what is the rom with best battery life (out of your experience) pls?
The CM7 ROMs were epic as far as battery life is concerned. Unfortunately the JB ROMs don't do well compared to those but they can run about equal to the stock Amazon from what I've seen. I've tried Jandycane, PA, AOKP and the CM10 with Linaro enhancements and they all seem to average out to almost the same, someone please correct me if I'm wrong. I've tried so many tricks and tweaks to squeeze more juice out and that doesn't really help.
Yesterday I was down to 45% battery after only 3.5hrs of use BUT I was doing alot of downloading and other procedures that took alot of CPU power. That was running Jandycane and now I've switched back to CM10 (Linaro) and I'm purposely leaving out the Gapps including the market (always seems to run in the background) to see if it'll help.
Remember that the factory specs on a Kindle Fire (stock) specify 8hrs of battery life of course weighing heavily on usage.
thanks for the info guitarman2010
I'm using aokp build 5 and the battery life was pretty good for beig the first day of using the ROM so I'm curios to see how it does after a couple of full charges
Im running aliendroid and battery life is pretty good, very pleased with it..

Sorry to get off topic but here is a screen shot from light usage on a CM7 ROM (Barebones). I just rooted my wife's Kindle and installed CM7 on hers and that made me miss the awesome battery life from CM7, especially when the tablet is sleeping. So back to Gingerbread for me until more tweaks are done with the newer kernal!
I have CM7 as second OS, and i'm amazed at battery life... In standby I roughly get 1% drain every ~20hrs... That's just crazy
On the other hand, JB drains 0.7% per hour... that's 14% in 20 hours... which is alot for a device which is just sitting there, screen off, wifi off, doing nothing at all

Yes. That tends to be one of the bigger complaints about CM10.
i think cm10 is default tailored more towards performance, you can tweak it or go with a liquid rom if your concern is battery life, i also recomend taking a look at something like this:
http://www.droidxforums.com/forum/droid-x-hacking-guides/14714-how-optimize-battery-life-speed.html
this guy seems to know his stuff, i personally prefer performance over battery life thats why i own a p930 to begin with. but i perform the battery calibration twice a month using his steps, and ive seen it improve my battery life durastically, you might want to start there and tweak according to your needs.
It has been reported that cm10 kernel keeps waking up the phone, i.e. no real deep sleep, causing a more drastic battery drain. work is being done to fix all the bugs with cm10, you may give Quattrimus a try, I found it very good with battery, especially true for rc2 (last version):good:
---------- Post added at 06:28 AM ---------- Previous post was at 06:19 AM ----------
I cant edit the post so here is the link to Quattrimus. good luck!
interesting never heard this, since 10.1 releases are starting to come out, the real question now is, have they fixed that bug for 10.1, the answer is probably yes if they were aware of it in 10.0 but it would be nice if someone knows for sure
edit was just spelling
Even factory ICS is not as great as Gingerbread. But yeah, running CM10, my P930 feels like a space shuttle ... in that it must remain tethered right until takeoff.

If I had just done a bit more research on CM10 for the Nitro I probably wouldn't have put it on there. Oh well. The good this is that I do have JB now.
DS battery saver provides decent battery life with moderate use. Now all we need are fixes to the kernel/ROM to provide better battery life when actually using the phone because DS battery saver is mainly for screen off.

I noticed my phone gets HOT on CM10. Haven't tried any CM10.1 ROMs yet. I'm guessing the kernel needs a bit of tinkering to get it running efficiently with our hardware. Battery drains fast even idling. I don't think the phone ever goes to deep sleep.
It definitely goes deep sleep, according to better battery stats app anyway. I'm really digging cm10.1, especially oc'd using windkernal (scoring 4000+ in quadrant consistently). The nitro is a complete beast right now, but I dunno if I can afford to sacrifice the battery life so drastically for a little performance.

Battery Life

Am I the only person who notices that all these battery save kernels aren't working for them. I flashed CM and I have been getting amazing battery life (13+ hours) with moderate usage, but with leankernel for example, I only get 9 hours max and my phone heats up a lot.

Not working for "them"? Or for you? Of course they do not work for everyone. They also may work well for one ROM but poorly on another.
Well I was curious how kernels worked for others. Sorry.

No two phones work the same. I've had my S3 for about 2 weeks and have run Stock-rooted, and e few custom roms. I have 4 email accounts-pushed, 10 screen widgets, and always texting, web surfing, etc. I'm currently at 14 hours with 49% remaining. When I work in spreadsheets, and use a a reader, (usually 2 hours each) I still get 14-16 hours, no matter what rom/kernel I've been running

You just need to find the ROM and kernel combo that works well with your phone. I have tried ROMs/kernel combos that some get excellent battery life from but mine is horrible and vice versa. Keep testing as it is a trial and error type thing. Also your kernel settings can make huge differences. What works for one may not work well with your phone. Different settings on the same kernel may net you excellent results.

I have noticed battery life tends to vary wildly depending on ROMs and even people. I guess I don't use my phone all day long, but on a TouchWIZ 4.1 ROM, the app "Battery Left" (from Play Store, its free) reports that I can get up to 46 hours on a full charge, based on my typical usage patterns (and if I use Greenify). On the other hand, I have used an AOSP 4.2.2 ROM in the past (such as LiquidSmooth), and Battery Left will tell me, after a few days, that I will get about 25 hours on a full charge (again, with Greenify). I have to do more testing, but there is definitely some difference between ROMs and battery life...

I read this thread & thought battery life has as much to do with what's running in terms of synching, background data, services, connectivity etc.

I am using one of the unofficial CM11 ports that is supported nightly and have been getting terrible battery life. I hate to ask the question which is the "best", but what would be a good kernel to flash?
I do not do much heavy gaming either. In fact, I do not do any gaming. Just casual browsing.

Well before I suggest any kind of "good kernel to flash" I want to make note of something. If you're running a nightly of an unsupported version of CM11 then don't expect great battery life. This has little to do with what you're doing on the phone but the purpose of nightly's is to have users report bugs. Many of these bugs are the kind that can drain battery rather quickly. So the first thing I'd do is find a stable AOSP rom to run on before thinking about kernels.
That being said, a kernel universally accepted as "good" is KT747 by Koonsez

Thanks for the reply bud. I personally like supporting the nightly versions of ROMs but I wasn't thinking the reporting that I do is causing that much of a battery drain.
I may consider today to go to a stable AOSP ROM that isn't nightly.

I have been flashing ROMs now for the past 4 years. I have never really got into the nitty gritty of anything specific but probably best I do. One question I had in regards to all these ROMs is, do they not come with their own Kernel which I would have assumed is the best recommended for the given ROM. When i see battery life of 14+hrs with room to go, I must be doing something wrong.
Thank you for any info in advance.
