[Discussion] Best Battery Life

Which ROM&Kernel Combination gave you the best battery life?
I have to improve my battery life and i can't find the right combination.

trial and error, each kernal/rom is different for everyone

pretty much. every device behaves differently I found.
Whatever combination you try though make sure you give it 2-3 days before judging it.
For me I'm using speedmod kernel + CheckRom HD. It's a great balance between battery life and performance. I use the 2000 mAh samsung battery and never have to worry during the day about my battery. Just plug it in when I go to sleep.
All the best!

I think Sensation ROM is the best. Cuz, very long battery life about 3-4 days in normal use(without open 3g or wifi). And, very stable for me

You're going to have to try various combinations out for yourself. Using the same combination as someone else on the basis of them saying "This rom/kernel combination gives me teh awesomz battery life !" will almost certainly lead to you being disappointed.
The reasons for that are:- No two phones come out of the factory the same (components do vary, mostly slightly, sometimes a lot), no two users will have the same usage patterns and no two users will have their phones setup the same.
Sooo....Get reading. Read the various threads about the various roms/kernels, take particular note of other people's experiences with same to give you a guide. And ask questions there if necessary.
Asking vague questions like this will ultimately waste your time.
Edit - Notice how so far you've only had answers from "newer" forum members ? There's a reason for that. Read my post again, the hint's in there

+1 on this.

I have no battery complaints. Why???? Because I have 3 spare batteries. I advise anyone who has issues with battery life to do the same.

My phone lasts weeks if I don't touch it and leave it in airplane mode! Wooooo!
There's a new "what ROM/kernel thread" every couple of days and I always read them for some reason. I think I have a pathological need to get these things marked as read but I don't want to just click the "Mark This Forum Read" button.
Really, every ROM I've used gets me through at least one day of normal use, and my varying usage patterns have much, much more impact than ROM. My advice is one of two things: either use a ROM you're comfortable with and just don't mess with it too much, or develop ORD and flash ROMs every few days. Either way you're probably gonna be fine.

CheckROM v4 and SiyahKernel i get just over a day of constant use, and around 3 to 4 days of moderate use using standard battery and a few battery saving tips mentioned previously.

CM7 + siyah kernel
so far i've been using CM7 + siyah kernel and it can last me a day with moderate use...just use 2G instead of 3G if u r not using the internet..2G is more than enough for my background apps that needs data for push notification(ie facebook,mail,whatsapp etc...)

[Q] Suitable kernel for 2-way recordings

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.. 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.

All devices react differently with different kernels and roms. That's why there are people that say this kernel is better than the other. Franco is a good starting point. if it's not good, try another kernel. That's the only way YOU will know.

as far as i know, battery life isnt bad on any of the kernels, it would mostly depend on your setup and your usage. if you go into any of the kernel threads, there will be someone that claims that it gives the best battery life. now performance of these kernels do vary, this is where they differ from each other. itll also depend on what your personal idea of performance is. try a different kernel every few days,, it only takes a few minutes to flash, youll find a favorite. just remember, battery life will be more accurate on the 2nd or 3rd battery cycle.

The stock CM kernel works fine for me

I've tried a number of kernels whenever I see a new one released. My personal favorites for performance/battery combo are: Franco, Faux123, Trinity, AK. They each perform mildly different however, and like stated before the best way to find out what's best for you is to try them. Good luck!

I need your opinion

I need the help choosing ROM i don't care about performance what i am looking for is best battery. I am not sure but my battery draining way to fast.
Please help. I need my phone to last at least 12 hours.

I use sacs custom rom w/ kt kernel. I underclock it amd use a conservative cpu governer. I also use gsam battery monitor. I find that a ton of the battery is used by the screen. I keep it at the lowest level most of the time. When that's too dark I only go up enough for it to be viewable. I also turned off location services and all the gimmicks and useless stuff. Currently at 8 hours with 42% left.

i would say try a custom kernel.. i get better battery life rocking a custom kernel.. the stock MF9 kernel seems to give alot of users battery problems

It seems as though the reason why your phone is dying so quickly is that really low signal strength. Also, please attach a screenshot of the application use as well. Two hours isn't that bad of a screen time, I get around the same as well.

Try one of the stock debloated roms and go from there. You might not want to get into a custom rom, they are more for added tweaks and customization's. If youre not into that than just go stock, and maybe go back to the KT kernel. Ive had really good results with going stock and debloating myself.

No one can choose a ROM for you and no one knows better than YOU for what you like.
There is no substitute for reading about the software you are about to drastically alter your $700 device with.
Also no one uses their phone EXACTLY like you, have the same signal conditions, etc so most likely no one will get the same battery life as YOU

Best rom for most sot?

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?
Sent from my Nexus 6P using Tapatalk

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!
