Kernel Battery Test - Nexus 4 General

I decide after using franco's kernel for a long time..i think this is the only one i used ever since i buy my nexus.
So i decide to try other kernels too cause roms are the same minor differences so after using faux123 kernel for 1.5 day, i saw a great battery life compared to franco's, but i have to say that with franco's i used my phone alot and flashing all kind of stuff.
So i decide to at least give you an example of how kernels do with battery lifes.
So i used antutu tester that have a battery benchmark and give the kernels a try!
*REMEMBER THIS IS JUST A BENCHMARK, YOU HAVE TO USE THE KERNELS WITH NORMAL USE TO SEE THE TRUE USAGE OF THEM*
I started with faux cause i already had it in my phone so i give it a try...
1) Faux 015m took 1H and 42m to go from 100% to 18% The drain per hour -26.1% and average Temp 44.6C
2) Franco 147n took 1H and 50m to go from 100% to 19% The drain per hour -25.3% and average Temp 41.0C
3) Trinity TF131 took 1H and 35m to go from 100% to 19% The drain per hour -28.1% and average Temp 41.0C
Its a long an borring procedure thats why from last night till today i have only test those too kernels...i will test also trinity, airkernel and semaphone
Also im not so good with excel there are years passed that i haven't touched it so i wasn't be able to find the drain per hour formula in excel!
I hope i found it!! ^_^! Correct anything you found wrong in the spreadsheet!!!
Nexus 4 Kernel Benchmarks Spreadsheet
Thanks and i hope that you may find it usefull!!
*INFO*
For this test i use AnTuTu Tester. Im not changing anything on kernels except the Volts, im UV -100mA on every kernel.
For ROM im using the latest PA 2/6 3.60 with all my apps installed (140+/- apps) with full brightness (default when benchmark starts) wifi open and 2G network with data off!
All background apps closed and no other procceses happent on the time the benchmark runs!
My only concern is that at least for now both faux and franco's kernel have the same results the differences are minor!So maybe all kernels work the same with the same power usage or antutu tester isn't the best realible application...we will know when i finish testing all kernels!

Very useful, we could add matrix kernel to the test It is interesting to see which one has better battery life.

I saw matrix but i think its in a state of abandonment so thats why i didn't include this and motley too!!!

Matrix kernel is not abandoned, on the contrary tomorrow is going to be 9.0 version released.

matrix kernel isnt abandoned! Version 9 is due soonish!
Look forward to reading more results .

Cant wait for the results :victory:

very goog idea please include the other kernels like matr1x and trinity and so on. keep up good work! many things depend on mobile configuration but it gives a little view. thanks!

Just finish the trinity test...here are the results..update the OT and Spreadsheet!!
3) Trinity TF131 took 1H and 35m to go from 100% to 19% The average drain was 59.5% and it have drain per hour -28.1% and average Temp 41.0C

There is a thread in place here, use it...thanks.

[Q] Fastest Rom & Best Battery Life

Does anyone have any recommendations for a rom that is pretty fast and smooth while having great battery life. Also any tips to get really good battery life such as processor speed and kernels etc..any opinions appreciated.
I use jaybobs aosp or cm7 with .29 kernel so I can use my headset. I use setcpu and clock 576/691 at full power then drop it if battery gets too low or raise it when I'm charging. The only way you'd extend battery life drastic is to live with a good signal and actively manage your data connections and sync.

hmm i will try it ive used cm7 and aosp but they seem to lag for me when im using the keyboard alot but ill try that kernel and see how that goes. I guess what you said about the battery life make sense cause i live in a area with pretty bad sprint service. guess i can fix that by turning off data while i plan to not use my phone thanks for your respond. Anybody else have any suggestions?
I recently just installed jaybobs rom (august 14th) like 4 days ago. I use the kernel .35 CPU=480min/710max
along with the v8 tweaks, and firerats.
As of right now my battery is 19h 29m 0s on battery at 21% battery level
Texted a lot, talked for a few minutes, update apps on market. I only use it to talk and chat cause i have a tablet that i do my surfing or gaming stuff =P

Could you send me a link to this v8 tweak? Ive never heard of it but im willing to try anything i usually get about 12 hours battery life.
I don't think the v8 helps the battery, i think it's just for performance. u should try it without it first.
heres the link to the v6 tweaks

What do you do on your phone? 12 hours is pretty good.

Well im running OMFGB August 12 nightly its one of the fastest and smoothest 2.3 rom ive ever used i havent used the aosp verion though so i dont know how smooth that one is. And i have email syncing and facebook and i use google voice a lot i mostly do texting and i keep my homescreens without any widgets that need to update a lot. i also calibrated my battery so i could get pretty decent battery life which in my opinion is 12 Hours but im still looking on ways to improve it.
ohh, i see. Yeah i know where ya comin from, I've done a lot of flashing and just decided to go with the most stable. They were all somewhat smooth but as for battery life, I've gotten the best battery with jaybobs rom.

For Battery life I would recommend extended 1900mAh batteries.
I didn't have to buy custom cover since they fit in the stock back cover.
2 batteries with external charger with shipping would cost you about $20.
I get about 2 days on a single charge with moderate use.
I am using CM7.1 nightly 160 at the moment.
If you are interested let me know I will point you towards the retailer
I bought them from on Amazon/Ebay.
Well im going to try jaybobs rom then and see how that does yesterday with OMFGB rom i got 11h 59m 2s and after that it shortly died off and im just running setcpu at 729 max 691 min performance lol i think i really need to change that if i want save battery does any one have any good setcpu profiles they would recommend? And i might look towards buying a extended battery but i dont really want to seeing as my upgrade is in december.

Well that is what killing your batteries right there
I am no expert but I will tell you what I use,
I only use 1 profile besides the main one on setCpu:
Screen On/Main: 691 max 176 min (On Demand)
Screen Off: Max 264 min 19 On Demand ( Since I dont use it for music or anything else screen off with min 19 is no issue for me)
By the I also use v6 Super Charger and V8 kernel tweaks and they do make
your phone very snappy and responsive!!
Best of luck
I recently flashed gingerbread hero deck and it's pretty nice. But, something weird I notice is that my 3g download speeds have dropped off considerably (from 1200kbps range to 600). I can't explain it. I was on aosp's 5-23 rom before. I also recently started using firerats mod. Not sure what's up.
Sent from my HERO200 using XDA App
Its the build prop that causes it. I'd use the V8 3g tweaks to see if it helps.
okay ive installed OMFGB 1.3.1 nightly 8/17 and with the V6 scirpt runs well along with the v8 and the 3g one which i cant recall the name of but everything now runs really good but im still calibrating the battery so i still have to see how that goes but so far its been good. Thanks for the tips everyone now to try out this jaybobs kernel hopefully everything will still work well.

best gingerbread rom and kernel with great perfomance and battery life?

please share
is there any custom gingerbread rom with bloatware removed and big free ram? and a kernel with OC/UV? plus great game compability?
how about MIUI?
Have yet to find one to best DjangoMouche 1.2.1 its GB 2.3.4 its customized, with different themes to choose from and a good bunch of performance tweaks. everything has been running smooth.
games run well, things load fast
I'm using Gueste overclock v1.8.1 kernel but thats up to choice. i found it works great between 900 - 1300mhz. but above that its rebooted on me a few times.
You could try Temasek's CM7 Rom with it's own kernel, it has OC/UV and all that things.. Run's pretty smooth and stable but i can recommend you to use GO Launcher EX with an ICS Theme :good:

I agree that DJ is one of the best ROMs...no doubt
but could i ask you why DJ 1.2.1 and not the DJ 1.5RC1....I am using the latest and it is more than a magical dream....out of the stars and heaven....I am curious why you are with an older version....

Currently on DJ 1.5RC1 and have to say it is truly magical.The feel of performance,smoothness and speed is just incredible.Always try to experiment with other GB roms and always drawn back to DJ ROM.DJ roms provide many choices according to our needs and customization as we like with transformation packs.So have to say this is the best choice i will ever have:cyclops:
Same here, Django Manouche, currently 1.5 RC1, but I am using latest spica kernel ;-)

Hi, this is my first post here. I have been flashing various roms and a few basebands and rils in my quest to get better battery life from my LG Optimus 2x. In the end. Most of what I have done is experimental and I can not say I understand much about versions and combinations. Last night, I read quite a few posts about the Django Manouche rom and downloaded all the three versions of the 1.6, the stock, the Spica and the Gueste.
Flashing led to boot looping on the Spica rom, powering off on the Gueste rom while on the stock 1.6s it ran OK, with some applications not running until I rebooted.
I came from a stock LG rom and was wondering if I need to change the baseband and kernel also, for these to work.
Any advice is welcome. Thanks in advance.
I think these "best rom" threads are forbidden but I'll give my 2 cents anyway, in case I'm wrong:
for me the best rom is Gueste Hybrid revolutions 3.7, is a hybrid between stock Rom and cm7.2, and symbiosis kernel 1.3.
I get great performance, great battery life, great ram management. I can't really complain, I'm so satisfied that I'm not that eager to get ICS (at least not as much as I was before).
LG optimus 2x, rom Gueste Hybrid 3.7
@daas88. Taking your advice, I have flashed the same combination as you, just this morning. I have been very active on the phone since then, so I can't tell right away, if there is any improvement in battery life.
By the way, I continue to be on the 20i baseband.
I shall report back soon.
Temasek
Probably the cleanest install would be Temasek. A very stable CM7 build. It's sort of finished, and offers a great experience. Use it with Temasek's, Spica's or symbi0sis kernel.
I've tried DM and it's great, but this just feels cleaner.
gl!
I have been reading about the Temasek rom. What is your view on its battery consumption? That is something I am focussing on. The stock LG set up lasts for about 9-11 hours on my phone, with full 3G, about 4 hours of wifi usage and about 1-2 hour of music (Neutron music player). I have a battery pack that I carry with me to work, but it is a big bother.
So, basically, to me battery life is top priority. If I can extend it to 12-15 hours, I am home and dry.
I've used Temasek for a long period of time, and though I don't want to go back to gingerbread (currently on Paranoid Android) I do miss the battery life. With Temasek (or stock CM7) I would get about 32 hours of battery life: a day and a night. This with some browsing, playing music checking e-mail.
Overclocking would lose you some of that time, but the toggle2g app would win it back. :good:

i have cm7 135 from temasek but battery is not so great have bb 218 and ril its the best right now but battery hold max 3h screen on and with 15-17h on time, it sucks, so i want to try dj mouche v20s with bb and rill and hope to get better battery life....
because if a old galaxy s1 can get 1day easy and 4h++ screen on, the fricking lg must get some were neer also......
stanby is **** i find on this phone dont know if its normal but yeah.
i say try dj mango mouch and flash also v20s bb and i think battery will be great and performance i think they are the same

Increased CPU performance, larger screen and stagnated battery technology will do this
As for battery life, I do miss my Nokia 3210! :laugh:
A small update. I charged my phone to 100% yesterday evening at 7 PM. From then on till now, what I observe is that with the phone in standby mode, the battery consumption curve remains almost flat. But the moment I start using some apps, for instance the Number links game for 15-20 minutes, the battery level drops by 10%.
This is with the Gueste Hybrid ROM and the Symbiosis kernel.
Further update: The battery went to 14% and then I charged it. 15 hours. Some improvement. It may be too early to comment, but this set up seems to work superbly when the phone is on standby. When the phone is in use, the consumption seems to be high. Could it be improved by changing the BB or the ril?

my record was 6 hours of screen on time with a cm7 rom and etana kernel with ds battery driver. but now i cant get even 4h screen on time with the same config (only updated versions) :/

Your best combination of kernel & roms for NEXUS 4

Hi everybody,
i´ve started this thread because of getting a view of your experiences of good kernel rom combinations. For every user there are different expectations so i´ve decided to categorize in 3 different sections.
1. Battery Usage
longest battery lifetime - depends on each configuration sure but where did you get the best goal for you
2. Performance
based on user experience - not benchmark
3. Usabiltity
your favourite combination for daily use for balance of performance and speed
Please post for which category you provide your post and write some comments why this is the best combination for you. So let's start to share your experience
:fingers-crossed:
I will start
Battery
For until now is the best combination for battery saving for me this:
Rom: Carbon Rom 1.7
Kernel: Matr1x Kernel 9.0 (non overclocked)
Changing kernel from stock of carbon to matr1x pushed my battery life huge. At this time this is the best combination for me for battery life

Nice idea but:
1. Users all have different setups regarding installed roms,apps, widgets, mods and usage.So its very hard to compare screenontime/batterylife.
2. By performance you mean synthethic benchmarks or user experience?
3. Usability! What do you mean exactly by that?
As said don`t want to nitpick but specify the parameters
Me personaly i use Stock 4.2.2 rom and Franco nightlie r148.

For me PA&AK kernel is the best...I came from Galaxy Nexus btw..

So i'm running P.A 3.60 combined with matrix kernel 8.5 on my nexus 4. I used trickster mod to change it to 2 cpus in use only and its still silky smooth and handles all the games i play still. With Gpu overclocked and limiting the 2 cores in use to 1Ghz when i'm barely using the phone plus display set to about 50% brightness (mabye too high for indoor use but i just love the screen), i got 20+ hours with wi-fi on constantly, and using social networks (facebook, whats app, sent about 100 sms in the day, plus 4 hours of call time) with 18% left. I think thats good enough

thank you for your settings. can you detailed explain what modifications you've done in trickster mod?
CPU Cores max frequencies / 4 Cores or??
GPU Cores max frequencies / limited to number of cores?
I want to mess up my battery life
thank you
I use Stock ROM and faux123 15tbm kernel
In dual core mode at a maximum clock of 1728 MHz and minimum of 214 with -100mv of UV I had 16 hours of battery time. 4 hours of screen time with normal use, music, gps, chrome and what's app.
The usability its better than stock kernel.
I never had lag issues or bugs.
My best and only at the moment is CM 10.1 + Franco Kernel.
On 2G, wifi on, auto brightness , I've been getting 40 minutes of screen (browsing, on Facebook, etc) at each 10 percent of battery.

Hello. I'm on stock 4.2.2 and enhanced stock faux kernel. Stock is fast and pretty stable in this combination. I want try something different but when I try CM with faux kernel it become unstable. Why I'm using faux kernel? Because I'm using Trickster Mod. Which ROM working good with faux kernels? PA maybe?

Guys, can you please add the section? Nobody knows for which goal is your combination good! Thanks in advance!
Stock + Franco Nightly
I want a flawless system so I stay on stock Android + I don't have the time to maintain nightly updated ROMs like CM, although I really like CM, especially its free customization... But doing those customization = Eat up my time for studying... So I decide to keep me and my N4 away from them
However I cannot accept the battery life and CPU management of the stock kernel so I chose Franco Kernel. I nearly do not play games and I accept seldom lags. My main use is browsing the web (often open up to 10 tabs ) and texting. My battery usually lasts for one day with ~5 hours of on-screen time and it's satisfying.
Running Carbon 1.7 with the latest Trinity kernel (131). Looks pretty solid so far.
Stock + Motley's kernel, with 2.5 days uptime + 3 hours SOT. Can't complain there.
Carbon 1.7, Franco latest nightlie using the BeastlyBattery power mode. On average 5hours screen on time.

[Q] [HELP] Battery Draining HELL FAST

This is my first post . I have been searching about battery drain issues from about 2 months. Yes ! two months ! now I found it better to ask it myself. I have a GT-I9000 with 1650mA Samsung's battery, the problem is that , one point drains in around 3 - 4 minutes maximum. I am using CM10.1 , i have tried about a thousand roms , several kernels just checking for the battery life . On stock gingerbread rom i usually get 5 minutes for a single point with wifi and cellular data OFF . Now I am really exhausted trying different roms and kernel ( flashing 10 times a day and sticking to my phone checking battery , is really now pissing me off ). All I want to know is that ? Is this okay ? 3 minutes for a single point on jellybean roms and 5 minutes on gingerbread ones ? tried every kernel no oc no overclock , nothing. Is it about more cpu usage on jellybean roms ? what should i do now i really am pissed off totally. how many minutes does it take for your phone for a 1% to drop ?
If you use your phone, then it's normal that 1% drop per 3-5 minutes but if it's in sleep, well then its draining fast so i think your battery is broken.

Its normal to experience less battery on JB roms because JB as a whole is a more demanding version of Android. Project Butter- 60fps hardware acceleration- while making the phone buttery smooth, is definitely going to take a toll on both the processor and in turn the battery. There are SO many things in Jelly Bean that will definitely have a significant impact on your battery life, compared to stock Gingerbread.
I've had cases where I've drained almost all my battery just setting up my phone.
As compacity said, choose a rom and a kernel that you think you like, give it a few days (charge/discharge cycles more rather) and then post a screenshot of your battery stats. Once you install a rom in needs time to calibrate, which is done through the charge/discharge cycles. You might fnd that you actually have pretty good usage
Oh, and when you do take your screenshot, just for clarity please state whether you've underclocked, changed governor etc.

Well I'm on stock most of the time because I'm out and about quite often so I need some pretty stable battery life...
But some pretty good combos I've had (and do remember that these are only prsonal results, you will have to try them yourself- it does take trial and error)
Roms:
-RemICS-JB
-Liquidsmooth
-Gamerzrom
-EXTRAordinary
-Slim Bean
Kernels:
-Semaphore
-Mackay
-Latrop
But again, purely personal experimenting and flashing. Those are only what I've gotten decent/good battery life with before

[Q] Best ROM/Kernel combination for battery life?

Hello World! What's your current ROM and kernel you're running on, and what do you normally get for screen on time? I'd like to get some suggestions.. Would like to get through a whole day comfortably
It doesn't really matter how much screen on time someone else gets, it doesn't mean you'll ever achieve that same amount. Screen uses a pretty constant amount of power per brightness setting, but the other things that use power will take away from that and not all those things are to do with CPU usage, which is the only thing a ROM/Kernel can affect.
On top of which:
"Best" ROM.
There is no such thing as a best ROM. The question itself is ambiguous. "Best" is obviously a subjective term.
What I want from a ROM may well differ from what you want from a ROM, ergo - what is best for me could be worst for you.
If you are asking what the most popular ROMs are, or which ROMs people are using, you can see which threads stay around on the first few pages (and have the most posts) in the Android Development or Original Android Development forums. You can also see what other people are running by reading the What are you running on your Nexus 5 thread.
If you are asking which is the most stable, being a Nexus device - they're all pretty stable.
If you are asking which is best on Battery, ROMs only affect battery if they have a feature that is badly coded. You will likely be able to read about this in the ROM threads. ROMs do not impact battery life. The only impact to battery life are your apps, your settings, how you use the phone and mostly, environmental issues such as Phone Signal.
For tips about improving battery life, please read [Battery Life Help] Troubleshoot battery issues here!
"Best" Kernel
There is no such thing as the "Best" kernel. What we all want from a kernel is different. Again, many people have the misconception that Kernels affect battery life. Let's get this cleared up. Although Kernel devs will build in optimisations and efficiencies that will improve battery life, these are very, VERY tiny...and if 1 kernel has these optimisations, they likely all have.
People will often say "Kernel x is better than kernel y for battery life". This is actually wrong. Kernels respond to user settings. Setting up the governor to favour either battery life or performance is simple enough to do, you just have to do some learning. The reason people think Kernel x is better than y is because developers set their kernels up with their preferred governor settings. This is what we refer to as out-of-the-box settings. The out-of-the-box settings for kernel x may well produce better battery results than the out-of-the-box settings for kernel y, which favour performance. The fact is, you as the user have the ability to tune kernel x or y to perform the same, be that battery or performance - so start learning how to do this yourselves - that way, you can choose the kernel based on the FEATURES you want, and not the fictional performance benefits of one kernel over another.
Hope this helps

Yup that does help... No such thing as 'best'. I didn't make the best title lol.. Currently happy with SlimLP and Franco, just wondering what you guys were getting . What are you on, as of now in terms of ROM/Kernel?

I hate the "it all depends on your phone, each one is different" bullcrap. That may be true to an extent, but some combos are generally going to be better than others. Besides, most people who ask this question just want to know what people are using and what is working for these people. So now that my rant is over, I'm using BrokenOS with Sensei Kernel R52. I'm getting roughly 4-5 hour SOT with roughly 50-60% brightness and 18 hours off the charger. I'm using the blacked out gapps that are linked with BrokenOS and using the black Swiftkey keyboard theme. All of the black saves battery when the screen is on because those pixels are off when using amoled screens. Don't know if you know that or not, but hey, it's there. Also, I've set the kernel minimum frequency to 223mhz using intelliplug with fsync and mpdecision off using the trickstermod app. I've set the scheduler to fiops and changed the read ahead value to 1024. This has consistently given me these results which I consider to be great! Hope that helps!

That helps greatly! Yes, this question was more of a 'Which ROM/Kernel is the best for you' type of question. And yup, I do know that AMOLEDs give you those pitch black blacks, which is good for battery, since those pixels aren't being used. I myself, am a big flashaholic, tried at least 5-6 Roms and a bunch of kernels.. Best battery life so far for me seems to be Slim + Franco.. Never tried BrokenOS, will flash tonight Thx a lot for your detailed response :good:

Each phone is different but that really has nothing to do with battery life, except that maybe some CPU's can undervolt more. I'm not sure anyone has given this "bullcrap" answer you eluded to.

Check out my rom chroma. Franco kernel is preloaded. Huge update coming very soon.

I've tried most of the roms and kernels and have always gone back to BlissPop and either Lean or Francos. BlissPop for the features and Lean/Franco for the battery life. I would consider myself a moderate to heavy user and get between 4 - 5 hours of sot, but more important to me, I start my day at 5am and shutdown around 10:30 - 11:00 pm and I generally have 35% - 40% or so left. Of course your milage may vary, I also greenify what I can, but I refuse to lose any features i use, why have a fantastic phone and cripple it. I generally don't change any of the kernels, except maybe set it to conservative, I've had issues in the past undervolting, but thats just me. For the slight battery savings I don't find it does that much. Again, my opinion.
Just take a nandroid of where you are and try some combinations. Give it a few days to settle in. Repeat until your happy with the combination.

Will most definitely flash Chroma... Looks like one of the best designed ROMs.. Will flash it either tonight or tomorrow morning... And your name seems familiar from the numerous pages I've went through on Franco's Kernel lol. Thx :laugh:
how many hour is stay on the stock ROM ?
Chroma with FK and vomer are poetry in motion. Use it and prosper.
using the rom that i use, and kernel, and the way i set up my cpu, i see between 5.5 and 7 hours sot. which rom and kernel? try them all out, find your best rom/kernel.

Does Chroma have omniswitch? Cause that's a deal breaker
Just flashed Chroma... This ROM is buttery smooth

I am on Terminus currently with Franco Kernel undervolted all frequencies @-50 which is 100% stable in my case. -75 crashes on games and/or benchmarks. My Snapdragon has a PVS 5 binning.

Nope, I personally don't find the feature useful.

Right now I'm on validus ROM with Franco kernel. I only changed the max clock in Franco kernel down to 2.2ghz. Right now I'm at almost 36 hours on time and 4 hours and 40 minutes sot
