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?

I don't believe his nexus is bricked...just wanted to find a kernel that consumes less battery.

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.. As a fellow user we are responsible for our own discretions and have to own up to our own mistakes. Isn't the whole point is to help yourself? 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?

oh, i dont think that you were being a douche in any way. quite opposite, youre being very helpful. but for him it could have been the worst battery life(whatever the reaons are. but battery is hard to judge from the first cycle since itll change after a few). anywho, i think its obvious what kernel i use, trinity. it gives me my best battery life. not to discount franciscos kernel, because its generally a great kernel also. the problem is, if you go into any kernel thread, and ask about battery life, every user will say that the kernel that they use is the best

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.

Iv always considered battery life a very important factor in my purchasing of a phone and was one of the big reasons i moved from my Desire HD to the Nexus S (amongst many others). However having been on the android scene for a while im used to tinkering with kernels and roms etc and due to the new battery graph in gingerbread im now able to make direct comparisons rom by rom and kernel by kernel to see how they all differ. This is all shown + explained below.
First id like to explain my method;
I install the rom and kernel with the same apps I always use and charge the phone fully until i am about to go to sleep. I then unplug the phone and leave it in the exactly the same place on my desk with exactly the same settings (sync intervals etc) and i kill all apps before i leave it just to make sure the test is fair.
In the morning i then take a screen shot of the battery life over the period of usually 8 hours and will upload this for you to see. I then look at the over-night battery drain as a comparison on how good battery life is on specific roms and kernels.
Justification - Many of you may be thinking who cares about standby battery life? I care about the battery when im using it!?
Well although that's valid there are many reasons i have taken this approach;
1. It is completely fair i.e. no individual differences such as 'im a heavy user' but we all have different definitions of a 'heavy user'. This is eliminated by the fact the phone is not used and thus the same every time (no individual differences)
2. If a phone has severe battery drain during sleep general knowledge should dictate that battery drain should increase when the screen is on, cpu is working and your syncing your facebook wall, thus a direct correlation with sleep battery drain and usage drain should be apparent.
Therefore i have decided over the next few days/weeks etc i will upload on a regular basis a screenshot of the battery drain over night, along with the battery use details and screen on time etc etc. In addition to the rom and kernel info and i hope that over time this proves to be a very useful thread.
I have been doing this over the last few days on a less strict system and there have been some VERY interesting results which i will upload over the next few days.
(Just a final note iv never really done anything like this on xda before so if its a stupid idea then please tell me now so i dont waste my time doing it, however if people are really interested please let me know and il make sure i do my best!!)
Thanks for reading my extremely long post!

SCREENSHOT 1: This was using modacos custom rom r10 and the kernel that comes with it, i had quite a short sleep (about 6 hours) but the curve pretty much shows what the point im trying to make is. The battery life is great!!
SCREENSHOT 2: This is CM7 Nightly build 27# with Netarchy's latest 1.2.1 kernel and although i didnt use the screen once of charge for a few minutes as you can see once the screen was off battery life barely decreased and was over a long period of time.
If anyone wants me to test specific combos please let me know.
I'm actually looking forward to reading your results.

I'd be interested in seeing CM7, just whatever nightly build you manage to catch.
I don't think that result will give you precise result.
I found that statistic is wrong sometimes.
It is better to measure using "play video loop".
So, find a movie, set to the same brightness and play in loop?

Unfortunately that will not give you how well the rom does while it is idle.
I'm really looking forward to your results. My only issue with this phone is the battery life is terrible. I ordered an extended battery off Ebay 3 weeks ago and have yet to receive it. Never ordering anything from Hong Kong again!

What were you using before that you consider this phone to have bad battery life? By far this phone has the best battery life of any Android device I've owned. If you want bad battery life, get an Evo. That is horrific battery life.

I am looking forward to the rest of these, however just a quick question. What was your battery use like in that situation with the stock ROM? Just for reference, because I'm thinking I might switch to modaco soon. Thanks!
More soon
Iv got a few more screenies but it seems i may have to end this thread prematurely. Its the SNS or 2.3 but idle battery usage for me is pretty much identical no matter what the kernel or rom (il upload a CM7 + Netarchy 1.2.1 shot top op). This was unexpected on my behalf because with my DHD kernels and roms had a big impact on idle battery consumption. I have noticed however that without a full wipe when changing some kernels such as with M r10 idle battery life can increase drastically. I will continue for the next few days and if i dont see any big changes i may move method to a video loop or something of the sort.
Interesting find
I found out something today that may interest may of you. I was messing around with the sleep profiles on SetCpu with netarchys kernel and i found that its better to leave the range from 100-800 than 100-400 or less. This i believe is because when the phone is asleep and carries out a process it will be forced to clock to the maximum of 400mhz and then stay at that speed for 10 seconds, instead of say going up to 800mhz for 1-2 seconds to complete the same process. So a tip to you would be set your profile to 100-800mhz conservative and see what you get!

This kinda enforces the point that SetCPU is useless for the NS unless you really want to overclock...
Any battery saving tactics used buy lowering screen off profiles are counteracted by the system process;( So i think in the context of battery life you are probably better to not use SetCPU

I would definitely move to a video loop or some other 'heavy use' task because when you think about it, not too much can really be changed when almost no power is being used in the first place.
You could also just mention your general feeling for the battery life of each rom, because quite often that is what I go by as my usage varies depending on a range of things (school day or weekend etc) .

Could you please test modaco r10 with Netarchy's latest 1.2.1 kernel ?
I would love to see the difference between modaco's default kernel vs netarchy's kernel.
On CM nightly 13, I just went 11 hours and I'm at 90%. That's 1/2% an hour. Not bad. That is with stock kernel.

This file (batterystats.bin) is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings. That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you. It has no impact on your battery life. -Diane Hackborn

True. No dev has said it improves battery. It is known it can get corrupted between roms and thats the reason we do it, so the real consumption is shown and achieved by device.

Obviously not since a Google Engineer felt the need to elaborate. Just look at the comments and you will see there is plenty of discussion about it. Your statement is equivalent to saying we dont need a noob guide because everybody already knows how to do it. Besides most people don't read these forums as much as we do so with all the misinformation it's good to get the word straight from Google. Also Google phones are still for sale last time I checked so maybe someone is just now joining us. Or maybe someone forgot to read their well known fact checklist that came with their phone lmao.
This is a message to all the devs who are planning to create their own masterpiece roms for the s3. one thing i would like to say is: Do whatever you have to do BUT please Make sure the battery consumption is taken into consideration when making the roms. we want longer battery life and not quick and short battery life
This phone doesn't have battery replacement for nothing. And a dock that can charge your phone and an extra battery at the same time.
But I agree. At least better then stock = a good step forward
good idea, i'll see what I can do, but not sure if its even possible.
This is not dev should be in general section. :what:

actually its the part of kernel developers. you can wait for a custom rom that comes with good battery life.
I think it's pretty logic that developers try to improve the battery life. I don't think you should have posted it x"D They will try their best, don't worry.
I would never make a post like this, to me this sounds incredibly demanding and strange. Maybe I just read too much into it, and maybe you didn't mean it like that. If I was a developer I wouldn't really appreciate something like this. I don't think there are very many ROM developers out there who actively work toward a shorter battery life in their ROMs.
I'm just going to keep quiet and appreciate the fact that some amazing devs are going to make some really cool stuff for this phone, absolutely free of charge. I won't make demands and I'll try not to pester them in any way. I'll try a few ROMs out and donate to the devs I feel are making the best stuff.
This sounds kinda goody-two-shoes, I know, but the tone of your post annoyed me, sorry about the rant...
im not killing any devs of saying that they make roms with low battery life. im just saying keep the battery consumption in mind. i wasnt ordering anyone or anything like that. if it seems like i did then im sorry, but i mean no harm. im just saying battery consumption should be focused upon

There is really nothing one size fits all kind of thing. Try these different ROMs for yourself to see what works best for you. It's hard to see which has better battery life since different users will have different usage stats.
I have to agree... One person might get great battery on RR and terrible on AICP, the next person the opposite. The only to really tell which one gets the best battery in your situation is to try them.
Data is too scattered to determine which ROM provides the best battery life. You see people getting all day battery life with different kernels, tweaks, usage, etc

I'm not trying to bash your post but TBH, any comparison you make from others is practically useless. As mentioned, people have different experiences on custom ROMs. One specific ROM might have excellent battery life on one phone and have horrible battery life on another of the same model. But there is an even more important factor that makes comparing across ROMs just as useless... Everyone uses their phone differently. Not just with apps they install, but with the features of a ROM they they decide to enable or not.
On that note, if you are considering a custom ROM, the best way to determine if it is right for you is simply to try them. Make backups that way you can revert back to the one you decide is best.
I know that every user use their phone differently. I don't know what made you guys think i don't know that. But what i am trying to compare is not overall battery life but battery life based on individual usage. Like when some one use that rom for only calls and get a lot of stand by time how much battery it drains. from that i can know how much battery it drains when kept idle. Same goes for using wifi or using mobile data , watching YouTube or reading PDF. I want to know how much battery that rom uses on what usage.
Sorry for my bad English. I hope you guys can understand what i am trying to say.

I understand this. But I think it would be easier to try for yourself, because to get say, me to try say 4 different ROMs, same usage, and then report back to you would be more time consuming than you trying for yourself.
I know you know that every user is different but the same user trying different ROMs for you just doesn't make sense.

Referencing individual usage as you have, along with any specific ROM across devices, you are not going to get consistent results. I understand you are trying to consolidate this data on one post, but there are to many variables involved.
To highlight: I could run AICP on my XT1575 with a clean install and no extra apps installed and make only calls and I might get excellent battery life on standby. But another XT1575 owner can do the exact same setup, make the same number and times of calls and get horrible battery life. This pretty much goes for any custom ROM, especially those not based on stock. This does not even account for differences in MM vs N. This also does not account for an update to a ROM screwing up battery life and the next one may fix it (which is relatively common). I've even seen where someone gets great battery life up to a certain update and thereafter it sucks, but another can experience the opposite.
And once again, individual usage still matters as individuals will have different apps installed, which can take up varying amounts of battery depending on background processes and syncing. This affects standby time and SOT to some degree. Also do not forget that the chipset on this phone is prone to negative affects on battery depending on cell signal strength, so that is another kink in observing and comparing battery life across users.
Ultimately, the best way to determine what gives you the best battery life is too rest ROMs for yourself and your specific usages.

I am not saying anyone to try different roms for me. I was just wanting them to post battery stat of the rom they use as their daily driver.

Yes ok. So we should be on the same page about different users using their devices differently. So if user A posts about say ROM B, and user B posts about ROM A, you know you can't compare. I would post my stats with RR but you couldn't compare to someone posting AICP stats as we are different users. The only way to be even somewhat accurate would be to get the same user to try different ROMs. Which you can do. Honestly just try the different ROMs! I will say with my experience though DU has not had the greatest battery life.

Well said!
@yk1999 As stated above as well as in my post, you just can't compare experiences of users across multiple devices and ROMs as there are to many variables involved. We understand what you are asking and we are telling you that there is only one way for you to get the information you are looking for. The only way for you to figure out what will have the best battery life in YOUR situation (how a ROM operates on YOUR specific device, YOUR selection of apps, and YOUR specific usage scenarios) is to test the ROMs for yourself.
Maybe there should be an app saving battery stats for the current ROM (internal storage or personal cloud), and comparing these personal stats with previous stats made when you had another ROM installed.
Of course there are other variables that affect the battery stats (like the apps installed, or the apps you actually open in a battery cycle) but at least the app would be able to list and compare battery stats on the same device and user.
Ie, I imagine a list like:
- ROM R1. Kernel K1. X1 apps installed. Battery rate: BR1
- ROM R1. Kernel K2. X1 apps installed. Battery rate: BR2
- ROM R2. Kernel K1. X1 apps installed. Battery rate: BR3
...
It could be able to group by Android version,...
I haven't found an app doing this. Do you know an app doing it? And, do you think this app would make any sense?
Anyone running this on your v20. Thinking about using it , would love to hear your opinion and thoughts.
TIA

It has its ups and downs. Apk is best imo. Not have as many errors. The news build has some bugs. AKT might still hold the crown. My supposed best screen on time is still very sceptical. My average is around 5-6 with average use with either or AKT/FDE. All these mods and yet still hard to choose what is really the best. I have a lot of stuff going tho, but my screen time should still be way better with these mods. I even have the 4200 mAh and still get normal times. Don't help that Kernel wakelocks suck, even with applied kernel Wakelock blocking.

Thanks for the info, will probably try the magisk module before buying the apk. I've been using AKT for a long time and agree it out performs all the other mods for battery life out there
