Hey folks,
I am giving two kernels out to test. Don't worry, both are quite stable. However, I am looking at some different settings to see which gives better battery life. So, in an effort to avoid any "placebo effect" results, I am not saying which settings these are just yet.
What I am looking for, if you folks could be so kind as to check:
Battery life between the two.
Performance between the two.
Neither of these kernels are overclocked.
Please test using the same governor between both, preferably Ondemand.
Thanks!!!

Ugh...you would drop this right when I just started doing a battery calibration.
Anybody test yet?
I am at work and can't till later.

I getting better battery life on a so far

I would love to help test, but I'd like to know if you have any good criteria for the testing. It's really hard to test something without any guidelines as maybe you end up using the phone more on one, or downloading or whatever, and both seem like 'moderate usage', but in reality they are quite different.
As a matter of fact, I'm having a hard time verifying the current draw on my phone, and knowing what is good or not good, in general.
Just use your phone as you normally would, for both.
Are these compatible with the new RRU?

Cool, I'll test both out for a day each and report back.
Kernel A has better battery life thus far here...
I get no 3G with A. That might be why battery life is better...B is fine.

How can you really tell how much better the battery life is in such a short amount of time to test?
This reminds me of a test that kmobs did back in the day for kernels on the nexus. Turned out that heavily undervolting the kernel has a negative impact on battery life. Where's jlevy at. I know he remembers.

Lol, that was quick. I'm thinking he wants testing to go a little more than 30 minutes with each.
I'll test out A for 12 hours and B for 12 hours, if you think that's suffiecent. That should get me through a full charge on each.
Should be sufficient.

That's correct. Stock voltage for the Nexus One was 975mV. Kmobs found that undervolting below 950mV had negative impacts on battery life.
Do i have to clear battery data everytime i switch kernels?

Hello,
I'm trying to use an app called Call Recorder. The app has an option to use two-way records, working only on custom kernel that supports this feature.
So I was trying to install Franco's kernel and it had the work done, but I found out it is KILLING my battery (very surprisingly actually). The stock kernel works great for me in battery and every other aspect.
My question is if there is a really close-to-stock kernel that supports two-way recording, and if there isn't I would be happy to have a piece of advice about a good kernel that isn't downgrading my battery level (or that is bad in any other aspect).
Thanks in advance.

First of I want to say that if you ever visited Franco's thread you know that he don't make kernels that drain out your battery. In fact the opposite. Have you tracked your app with 2 way recording could be the culprit of your battery drain? There isn't really any info from you on what you have enabled and disabled. Such as rogue apps that can eat up your memory, high voltages on top of your frequencies. Takers conflicting with each other. Basically anything conflicting with each other cause battery drain. Like CPU apps. What governor your using. Try adjusting your kernel to optimize battery life. Disable functions that you don't use. Get rid of any taskers. Android does a good job of managing memory on its own. Please do your research before you go blaming someone's kernel for your battery drain. FYI rogue apps have been known to cause wake locks so figure out what's causing that too if your suffering from that as well. 90% percent of the time its a user error on battery drain.
Have you tried this?

Hey.
You can assume, despite your habit, that I am not a complete retard. Of course my battery will drain if I change my usual activities and run software that drains my battery. You can assume that I didn't play hardcore games after installing the kernel and then go complain. His kernel, I don't care for the tech explanations, did cause me a battery drain and I can prove it. I didn't ask from you to argue about his kernel's quality but asked for advice about other one.
Your disrespectful comments won't help.
@mariosraptor, I'm sorry for not understanding how can unbricking tool solve my problem.

usually after flashing a new kernel, the battery for the first 2 cycles are inaccurate. the third cycle and after is usually much better.
I wasn't being disrespectful. Your the one who couldn't elaborate as to why your battery was draining so fast. If you knew what I told you then you would've tried all those things first beforecoming here to q n a and complaining about francos kernel. Where did I explain any of francos kernel features? Its very easy to know that his kernel is the best at battery life. I guarantee if you went on his thread complaining about how his kernel doesn't have your feature you would be met with laughter and a sarcastic response like "who has two thumbs and doesn't give a crap? Francisco Franco. How you doing?". Instead of taking my advice as a negative shot at your ego, maybe try them out and see if it improves. Honestly, I tried out every kernel in this forums and none of them that I know of support your "two-way recording feature". I don't even think its a kernel related issue at all. Since you love my advice so much I will give you one more piece. If your going to ask for a feature for a kernel, don't start off complaining about how this kernel or that kernel is the reason why your battery sucks at battery life. Not your own words but i figured that that's what a dev would see it as. You can take my responses any way you want it but bottom line. Your just another user not using his brain.instead of coming over here looking for someone to spoon feed you answers. Look for yourself. If you don't find what your looking for, be polite and request a feature instead of telling a dev their kernel drains your battery because I will tell you he may say something similar to my first response to your op. Have a nice day.
Edit: by the way, I looked at this call recorder app you spoke of. Now where does it say you need a custom kernel to enable two way calling feature. So this makes your argument invalid.

That's fine and thats a fair statement. But he was complaining that his kernel sucks his battery not to mention he was asking about a feature instead of looking for himself..

Dont we have to search amd research and try everything before we go complaining to the devs about how their kernel drains their battery?I wasnt trying to be a douche. I believe he has been around long enough to know the procedures before asking for help. I have to ask, what kernel are you using thats giving you good battery life?

Right right. Lol As they say, not all chips are created equal. Some kernels work better on ones persons device and may suck on another's. Which validates your point.

First of all, the kernel causes battery drain for ME and it's a fact that I could prove. Secondly, your advice is irrelevant because I probably wouldn't be complaining if I'd use things that drain my battery after installing his kernel (Doh?). Oh and the two-way recording worked on Franco's kernel if you didn't realize, and it doesn't work on stock. It is a kernel feature.
Anyways, it is not a discussion about Franco's kernel quality. if you don't believe that it causes battery drain for me it is your right, but it is not related to the thread (and I wouldn't "give a crap" about Franco's response to this, as you stated). The reasons I felt that your post was disrespectful are that you don't believe me that it causes my battery to drain and that you give me ways to save battery juice while I know how to do so, didn't ask for it and it is not relevant to my case at all.
If you're so smart and I can't be reasonable enough to know what's draining my battery, please take my piece of advice and don't waste your precious time on posting here at all.
Have a nice day.

There's many ways, learn to tweak your kernel, a good place to start is HERE - Lower screen birghtness, have a decent signal. If you're using your phone flat out it'll rinse your battery.
You got over 4hrs SOT in 12hrs from the average time on calculator, and 3 hrs real time more or less, that's actually not that bad, it's average-decent battery.
There's so many ways, you have to learn how your phone works really, it's all trial and error. There isn't a simple "get better battery" method.
Thanks for the input if my battery life is average then i wont worry about it anymore its just that i read a lot of users that can have 6 to 7 hours of screen time i thought my phone is defective

6-7 hours is achieved by pretty much using the device for nothing and disabling everything. People who have silly SOT's by putting the device in Airplane mode and having brightness on super low, and not using any app.
AOSP ROMs can have better battery life due to not not sucking up as many resources as a Samsung ROM. But again, you can tweak your kernel settings to suit your needs.

Thank you so much you have been very helpful, if i change my rom to AOSP how much more screentime will i get? Just an estimate is enough
Depending on the kernel you use, plus the ROM I guess 4-6 hours is achievable.
Sent from my Spectrum ZX +2
How about my case? I have 6 apps installed and on CM11 nightly, and only getting 3 hours SOT from 100% to 0%.
It's really all down to the kernel and the tweaking of it. CM stock kernel was never great for me either, use a custom one.
Sent from my Spectrum ZX +2
For the moment I run pure nexus with full satisfaction, I get a screen on time of 5 hours, which is great but longer is always better.
Is there a rom with very good battery control, kernel tweaked and all?

No
There's no such thing. What you're asking is a subjective question, it depends on the user. The only way to find out which is best for you is through your own testing.
If I might add, attaining the best SOT is mostly about what you're willing to sacrifice.. performance, brightness, connectivity, etc.
Hence, a lot of this will be relative to how you use your device as Heisenberg already stated.

Thanks mate, been a mod for a little over a year now. Good to see you around these parts
Everyone's milage varies. I'm on PN right now and will hit 5hrs sot today. Been off the charger for over 24 hrs too. That is something that people fail to mention sometime. On a fresh charge and constant use I'm sure I could hit between 6 or 7 sot. I just don't have that much to look at haha. PN is a good stable place to be to get great battery life and great performance. I often find myself looking for that ultimate set up and it becomes hard to judge because I use my phone differently everyday. Hope this helps

these kind of questions still exist.. XD well that is XDA for you!
to the OP's question, mate if i were you i would just try out a couple of different roms to test out the battery life.
(sorry no n6p user here, but i think you should give Roms a try that come with cmte, roms that come cm source might give you abit more battery life.) 5 hours sot is already very good , good luck!

I tried AKT on Classic rom with BTTF kernel on Ls997 and had no luck. Not sure if it was rom or kernel or what. Seemed to cut battery time in half instead of doubling. AKT would be sweet if I could get it to work right. Kernel already has no touchboost imbedded I guess btw.

Go figure...the first selection lol. I will test over a few days and see what comes about and then Ill post results.
Just a quick update so far... I am currently in midst of testing the Xana Extreme again because on my cell I was experiencing no lag or if any very slim and wanted to real test as I got it working properly via app version. The Zanah didnt seem to cause any issues as it also did increase a few hours of battery life. So far however with the Xana extreme I am currently on 26 hours since full charge and no plug since at 56% battery left. I know it is about SOT, but total life is just as important. No restarts as that kills the test. Im happy and impressed so far. Will post more after battery nears death

I'm currently on aokp rom so haven't tried this. I would suppose it should work with op3
Here is a shot of my initial rundown of a new 4100 mAh Li polymer battery that's the same size as the stock one (mentioned in the Accessories section and the V20 Subreddit), getting past 10 hours of screen-on time. You can ignore the averages section of the screenshot as it's the first run.
Setup: LS997, ClassicROM ZV7 | mk2000 BTTF kernel | AKT 1.6, OnePlus3/SD820, Project Zhana Battery profile
I also turn on aggressive doze when idling overnight using Naptime, dim the display down after sunset using CF.lumen, and auto-brightness is on.
So I decided to switch up atm because I wanted my GPU to not be bogged down at all. I checked the Xana battery in the balanced area and was fairly impressed. For absolute no bog down and fully clocked GPU/CPU for full performance and good battery I recommend this. Sure the results seem less, but my battery has also had hundreds of restarts and charges since I got it and who knows how many before hand. A brand new would show better. I also have a dynamic wallpaper and am running Dolby and Viper as well. Same kernel. Same rom. Same phone.
Also the pic shows 15% because phone died before I could get proper screenshot, the 95% is the key and results are still accurate.
This is my final post as to testing for this thread.

Mysticblaze,
I wanted to bring the conversation from "[Discussion] Improving efficiency and battery life of the V20." back to here since we started to get into some talk about this AKT.
There, you said, "I can get around 10hrs sot (depending) using Xana extreme battery. That's the one I'm currently on.
Have a 4200 mAh battery (reg size)"
1st - what ROM and kernel are you using with that?
2nd - is the battery 4200 or 3200 (mine's a 3200)?
3rd - any other settings I need to know about to pull 10 hours SOT?
Thank you so much!

Yes, 4200. It's a Shemnz. Got from eBay. Rom is Classic for ls997. Kernel is latest 7.0 mk2000. Hard to say on other settings. My test tho was an up to.
I left screen always on with a live wallpaper running with a covered proximity sensor for lowest Auto. Got about 10 and a half.
