Best battery life kernel on sense rom?

Hey guys, in your opinion what gives the best battery life on a sense ROM like Mikshift? BC's 1.5GHz, 1.8GHZ or X99, Scary Kernel, ect. Just curious what some of your experiences are..

I have been running mikshift since the beta along with bcnice20 oc uv 1.5 kernel with amazing battery life, if I forget my charger I don't even worry the standby time of that set up is just amazing ran for 24 hours on wifi with about 5 hours of using the net,tapatalk and about 75 texts and was at 50% at 24 hours of being unplugged its the only setup ill run, sometimes ill throw the 1.8 on there just to show everyone I can go that high but its never needed. I run at 1516 max 368 min conservative with a screen off profile for 806 max and 368 min no complaints here at all!! Its actually the only setup I'm willing to run!

Go with the x99 kernel without changing any settings. Just flash and leave it alone. Easy 2 days like that

What Kernel are you guys using on the lastest CM7?

How many .35 kernels are available? I'm only aware of Umaro's and the stock CM kernel. I'm trying to achieve better battery life, so what kernel are you guys using?
So far, using Umaro's, I'm getting regular battery life, nothing special. Haven't tried the stock CM kernel.
Are they any other undervolted kernels available?

There aren't any others so far. Umaro's kernel is really good for battery life, however it's not up to date with the latest kanged nightly from yesterday.

Ahh, I see. Thanks for the info.
What cpu settings are you running?

Right now I'm using a kanged nightly with the "stock" cpu settings of 245MHz min and 1024MHz max, but with the interactive governor. With Umaro's kernel I had at 245 min, 1017 max and the Smartass governor. The smartass is pretty good on battery.

u made all the right moves all i would do is dim screen and keep runnimg apps low.
pimped out g2

btw pyromod 2.0 345 ghz min 1405ghz max on smartass. i fully charge bout 1 a day
pimped out g2

Pershoot released his kernel the other day pretty nice and smooth

Alright I'm sleepy so this will be in rambling form but...
I've tried Umaro's and I'm not sure if it was the undervolting (which I haven't looked into tweaking) but my phone kept stuttering no matter which governor I used. I was using Htcclay's Super CM7 1.8 with cpu set to 245/1113
I also used the stock kernel that's been on CM7 with no problems and average to good battery life (10-15 hours of active use: texting, browsing, few calls, and playing the occasional game)
Most recently I've used Pershoots which I had heard worked great. I myself love it. Almost same battery life as stock kernel but everything felt just a little bit smoother performance wise.
Here's a link to Pershoot's thread:http://forum.xda-developers.com/showthread.php?t=847672

The stock cm kernel in my opinion is finally good enough that it doesn't need changed. I have always flashed pershoots and occassionally others, but it truly does not need supplemented IMHO.

You're running that on Vision? I can't seem to find it for our device.

Stock CM7 kernel here. I run 245/806 Interactive with automatic brightness. I've found that when wifi is on, keeping the cell radio @ 2G only works wonders. Wifi is set to sleep on screen off, but not when plugged in. 1 day 7 hours on this charge so far with 23% left. I would consider my use light to moderate.

I'm wondering where can I download the Umaro's kernel. I check out his github (https://github.com/umaro/htc-kernel-msm7x30) only to find out that the source is available.

Quest for the best battery life.

Day 1:
Flashed Simple and Clean v1.3
2.6.35.7 speedmod test3 k2 kernel
Juice Defender Ultimate in Agressive mode.
Batterylife: 11 hours. Lost most of the life when the phone and I were both asleep during the night. It went down from 100 to 38%...
PS: If anyone wants to give me their set up so I don't have to spend so long on this quest, that would be appreciated...

There are 2 more threads with the same topic, with much more info. Also, we know nothing about how you use your phone, except that you have huge wakelocks. Not really helpful tbh.

care to point out those threads for me?

you could actually use the search function
PS - Ditch Juice Defender it uses up as much battery as it saves, trust me this is fact.

I did. I tried some of the solutions posted in some threads like using speedmod + clean n simple, and also lightning v6.1 and ninphetamine kernel; doesn't work.

I used to have the Galaxy S Vibrant before I got the S2. I swore by Juice Defender. I would get on average 45-60% more battery depending on usage (phone was rooted with OCLF installed). My S2 gets an additional 2-3% more life while running juice defender. Takes more than that to run it. My opinion, remove the app.
I am running sensation 1.9 rom and hardcore speedmod kernel. I work oh average 11 hours a day. Phone isn't used much during that time. Wifi is always on and by the end of my shift, it's at 94% or so.
When I get home, my phone is put through some heavy use. Facebook, youtube, texting galore and internet browsing. I always have 25-30% battery left at the bare minimum written I go to bed at 6-8 hours later.
In my personal opinion, this rom and kernel combination give me the best power (4700 on quadrant), best options (configuration got nearly anything) and best battery life (phone lasts all day with ease). I would recommend this to anyone in a heartbeat.

I'd recommend the Hyperdroid rom. A lot of users (including myself) have hit 5 hours screen on time (most I've seen is 7 hours). Phone can easily last a whole day, just need to check for wakelocks using BBS. 60% overnight is ridiculous lol, you should really be losing 1% every 4-5 at least unless you have loads of people ringing you all night
My setup
Rom: Hyperdroid 2.9.0
Kernal: TWD2.5
UV with voltage control
200mhz - 1200mhz
Sio I/O - Lulzactive governer
Max Screen On Time - 5 Hours 28 Mins
Facebook/Whatsapp Syncing

Read the guide i posted yesterday, its a bit long, but will definately save you battery life.
http://forum.xda-developers.com/showthread.php?t=1351663
Also my setup is in my sig - very fast, very slick and above all great battery life (range between 20hrs and 28hrs moderate use)

I read the long thread. It has some points in there I didn't know about.
Will try HyperDroid Rom.
Tried Sensation. Battery life failed for me with that ROM. Will try it againwith speedmod kernel if HyperDroid doesn't work...
btw, what governor is the best for Hyperdroid?

i use
check/leo rom v 3.1.1
siyah kernel 2.2 beta6
ice cream sandwich theme
the kernel is set at smartass v2 governor
1.4ghz - 1300mv
1.2ghz - 1275mv
1ghz - 1150mv
800mhz - 1050mv
500mhz - 950mv
200mhz -900mv
100mhz - 875mv
my sgs2 doesnt like undervolting so them settings should be safe to use on most sgs2 handsets
i then have the following profiles
screen off 100mhz -- 200mhz
charging 100mhz -- 500mhz
in call 100mhz -- 500mhz
battery at 60% set cpu to 100mhz -- 1ghz
battery at 30% set cpu to 100mhz -- 800mhz
battery at 15% set cpu tp 100mhz -- 500mhz
getting excellent battery life with my sgs2
ive also frozen any apps i dont use via titanium and used a start up manager to stop certain programs starting at boot
i used to use juice defender but on the sgs2 it doesnt seem to wrk as well at all
i was getting wakelocks from facebook chat draining my battery so i have installed an app to auto close that when the screen goes off and that has saved me more battery and kept wakelocks down
as other users have said its all about how you use your phone , the settings above might be useless if you have lots of background tasks going on as a screen off profile off 100mhz -- 200mhz may not have enough power to do your background tasks however when my screen is off i want my phone to go to deep sleep and not consume power etc so a very low screen off profile suits my needs as does a low charging profile as i dont use my phone on charge and 500mhz max power suffices my needs for when the phone is charging
same goes for setting a battery % profile i know when my battery is at 15% i wont be playing high end 3d games so it makes sense for me to try and save battery and limit the cpu to 500mhz at that battery percentage but other users may want full power all the way till their battery dies , it all depends on what you want and do with your device

Day whatever:
Used Hyperdroid ROM: Battery Life is AMAZING!
Using their 2.5 TW kernel as well...
The first thing I did was restore all my apps with Titanium Backup, but then I got crappy battery life, so I reflashed the ROM but this time, I didn't restore any apps.
I got amazing battery life!
So it was an APP's fault!

yeah sometimes apps are rogue. Hyperdroid has an awesome kernal though, someones just hit over 8 hours screen on time with stock battery which is amazing. betterbatterystats would show you apps that are causing wakelock problems. I do use some app called gemini just so I can stop apps loading from boot (haven't been bothered to search for autostart apps). Fresh wipe is good sometimes though, fresh and clean is the way to go unless your upgrading from the same line of roms

DB i manage minimum screen on time with rom/kernel combo over 5hrs.....and it saved me money from getting a extended battery. why you think i aint been back on foxy yet...and even though i love raffaeles work (foxy and androidmeda is the top two) for me its all about battery life and that one has done it for me nxt stop though is ICS

CPU not idling properly in CM9

I'm currently running turl1's v8 with the kernel that comes with it. I've read about people having this issue with faux'd kernel and that they fixed it by using the one is turl's build. I've attached a pic of the Time in State screen from SetCPU.
Sent from my MB860 using XDA

I am using jokersax 0.3.1. Same issue.

do you guys have profiles set?

Only based on temperature. Do you?

I have profiles set when the screen turns off and such.
I still have idle problems, but its masked a little if you underclock to 912. and with hardware acceleration you can hardly notice it.

I I did have the idling problem with previous builds so I switched to turls1's. When the new 0.3.1 came out I switched back. I also changed from setcpu to antutu cpu master pro, and now it idles correctly.

I'm using turl1's V8 Kang with faux123 025 beta kernel (1.0Ghz), and here is my CPU freq for something like a week.
I use a profile for screen off- 216-608.

Now mine looks a lot better. But I didn't change anything..??

I'm not using a profile on mine either. I think I'm going to try faux's kernel and see if it improves any. I think I would get fairly great battery life if I could resolve this issue. I got down to only 84% after moderate screen time and video and music playback today with over 8 hours off of the charger. Most time was spent in 312Mhz with 608Mhz being the next highest and 216Mhz as the third.

My cpu seems to be working great on turl's v8 with the default kernel. I was getting pretty poor battery life on joker's ROM, but on Turls v8 I'm getting the best I've ever had; stock or not.
Sent from my MB860 using XDA

Running Jocker's latest with the latest Faux 1.3GHz kernel.
Idles mostly at 456MHz.
Something wrong there.

After flashing faux's 1Ghz kernel and setting a profile for screen off @216Mhz it has greatly improved. Although it seems any time the screen is on it never hits 216. My battery life didn't seem to get any better either which I find odd.
Sent from my MB860 using XDA

another vote for turl fixing batt life.
No idea why some people are so good on faux's but a large proportion have these massive problems.

I switched to turls v8 with the kernel it comes with and now my battery life and cpu usages are great!

told ya, mine looks around the same
tried to feed it back in jokersax forum, not sure if he's picked up on it or not, theres plenty of people saying 'great batt life' but theres enough of us out there who aren't getting that (and whom get decent results with turl). Maybe there are subtle hw differences in certain batches or revisions of the SoC or something like that.

I've never seen my atrix idle like that.

are you sure? Mine idled similar to that in CM7, now CM9 turl build.
In jokersax build (stock kernel) 0.2 I never got below 456Mhz consequently heat and battery died in ~10% an hour increments even if I didn't touch it

[Q] setcpu and evo battery life

hi
i have a htc evo 4g running android 2.3.5 and kernel 2.6.35.10-g4b48446 [email protected] #1 and i have a few questions on setcpu. its a stock rom and it is rooted.
I shut off my profiles and disabled the perflock - it said success. So i ran the long bench test and only got 2078 ms, not 5000. so i dont know if its really working. I reengaged the profiles and i think it works with the screen off. the rest of the time i am not so sure. in fact it seems to still drain fairly rapidly unless i turn on some battery saver or something. I have the following settings on my profile all are set to ondemand except charging which is set to performance. the only other setting i can choose is user
in call 998 max and 245 min priority 91
screen off 384 max and 245 min priority 88
charging any 998 max and 245 min priority 85
battery <25% 460 max 245 min priority 81
bbattery <50% 883 max 245 min priority 65
Temp> 42 C 614 max 245 min priority 50
what am i doing wrong? I have it enabled and i have notifications off
i have system panel to try and monitor but its not recording and it also drains the battery like crazy so i think thats set wrong as well but i dont know why.
i also tried juice defender but it doesnt work right because it says the AOSP file isnt found in the system/app folder. I looked there and also in teh data/app folder and its not there. So i dont know what to do about that.
thanks

stock sense is just not all that efficient really. (well thats my opinion) profiles seem to look ok but also finding a different kernel with different governors (smartass v2 is rather efficient and changing around the frequencies as needed)
auto sync settings as well? turning some stuff of that you dont use or look at and so on can help too
and calibrating battery a bit can help aka a full discharge a full charge and full discharge will sure help (also what i have found personally)

kernels
thanks for the reply. You mentioned different kernels. I understand about rooting my phone but not so much about how to load a different kernel or different rom. Where do i go to learn about that?

look around in the development section as there are some great kernels available right now...Ca1ne just released a new version of the underworld SBC v6 that i personally like with great battery life ...Mason kernels are also great with great battery...just make sure u read the threads completely to make sure u are using the right kernel for the rom u are using...ie there are kernels for ics...sense....and so on......also the kernels load through recovery...just load kernel to sd and wipe cashe and dalvik and flash zip...hope this helps...Carp

Hi another question about kernels. I am a bit of a newbie other than rooting my phone so i want to understand what advantages/disadvantages different kernels have. You mentioned smartassv2. i have seen others like
chopsuey kernal
freedom kernel
golden monkey kernel
savaged-zen kernel
tiamat kernel
all of these i think support sense roms.
as i understand it , you have to go into the recovery screen and load hte zip file off the sd card and reboot with the new kernel. What are the risks/rewards of doing so? I guess i am trying to understand which one would suit me best.
i have the current sprint lovers rom i guess since it is factory stock so should i also be considering changing the rom? Maybe i am getting ahead of myself here.
thank you again.

which rom are u wanting to run....this will help us steer u in the right direction
im sorry your entire post didnt load on my end i see ur running sprint stock....that is a fine rom but i have not ran it myself....
---------- Post added at 01:53 AM ---------- Previous post was at 01:36 AM ----------
i personally have switched to sbc kernels when they came out with a sense version...i am addicted to sense 3.5...just my personal likings...sbc is superior battery charging whichcarp will give u better full charge on your battery so when the light turns green and u unplug it it wont drop down to like 90% battery in just a few mins....i can squeeze another couple hours out of my battery with sbc and even more depending on light usage....but u will stil need to play around with different cpu speeds like 786..921 and so on to see what your individual evo can stand....what works for 1 may or will not work for another....lags and bootloops etc...

You don't need to change Roms, you can if you want, but changing kernels will unleash new features. Some features are:
Full hdmi mirroring
The ability to over/under clock CPU
2 way call recording
Improve battery charging
Enable swap space
Improved performance of phone
Some kernels allow under volting CPU to further save battery (this can cause some stability issues so start slow with undervolting)
You may want to take a look at Lionfish kernel also, just note first boot may take a while.
Also ditch the profiles in set CPU, I tried profiles and it never seemed to work right. A good governor will handle all your profile settings.
I like smartass, and intellidemand the most on my set up.
As an idea ok the battery life I am getting, I streamed Pandora over 3g for about 8 hours not much other phone use, screen off most of the time, and my phone was at like 20 %. I thought that was pretty good.

thanks detcup4evr for helping out explaining that better...i blew out my back and between no sleep and pain meds the brain just dont want to fire...thanks for stepping in bro....carp

smartassV2 vs InteractiveX ... which one giver better performance AND battery life??? currently I am running LIONFISH 1.8 with interactive X

Using profiles in setcpu actually uses more battery life. Because it has to be running all the time and monitoring phone state to know when to change to a different profile.
interactiveX vs smartassv2 all depends on how you use the phone and really which kernel it is. I've noticed little things like on mason's I got better battery with smartassv2 but on other kernels I get better battery with interactiveX. As far as performance, you won't realize a difference.

ok so it sounds like i should try the sbc sense 3.5 kernel with the smartassv2 governor. Did i get that right? i will look around to see where i can download that.

Were you refering to this kernel?
Underworld Sense Kernel v0.6

yes this is the kernel i run with ODJDub HD Bliss!! Sense 3.5...if u choose to run this rom it will give u alot of different options of kernels and apps and other things from the installer....if i can help u more just feel glad to hit me up....carp

Ok so with lionfish 1.8 kernel and interactivex, I should not use a profile? What does CPU go to on screen off? also where does it mention profiles use battery? I'd like to read more into this..

Sense rom with Underworld v 0.6
At Carp -
thank you for the advice. I was thinking maybe i would use my ROM still (its a sense i believe) and load the underworld v0.6 kernel with sbc and see how that goes. I havent done very much research on ROMs so i dont know that i want to get that deep into this just yet. It seems like underworld has alot of nice features. One thing that i am wonderig though is with the new kernel would have any further ability to unload some of the sprint bloatware or do i need a new rom to do that or is there another way to do it? Things like qik video , gmail, accuweather blockbuster etc all load themselves periodically. I kill them but then they come back like weeds. Even programs i do like , like pandora, wheres my droid etc come back also. But i dont want them to.

no u will be fine getting rid of apps and bloatware u dont wont...u wont need a special rom....i use a free app in the market called root uninstaller to get rid of useless bloatware,apps etc...then u can go in and manually uninstall what u don't want...be careful not to uninstall anything which the phone needs to boot and operate such as android system...you will see the things u are looking for when u load the app...hope this helps...carp

I actually did something unusual.
I have universal aggressive lionfish SBC 1.8, swagged out stock N, and smartassv2
I set the ideal, sleep, and wake freq for smartass v2 to 128, while setting the up rate to 245. I used set cpu to lower the min freq for my device to 128. I set max load to 100, and min load to 85, and down time to 0. I then set a profile for "ondemand" during screen off, of 128-384.
I actually have pretty awesome battery life (I'm an uber heavy user).
Sometimes it reads that I spend over 70% of my time at 128mhz.
I feel no lag. It clocks to 998mhz maybe 15% of the time, mainly when loading web pages.

flashed underworld v 0.6
Hi Carp,
well, i flashed the underworld v 0.6. So i see in set cpu that i can underclock to 128 and overclock to 1228. however, i slid the slider over to 1228 by accident and it froze the phone even though it says its still at 998 mhz. then it rebooted by itself. so i guess that wasnt a good idea. Anyway, theres a ton of governor choices now in the profiles section. i am not familiar with alot of them but i was wondering which of those would provide the most benefit. they are as follows -
ondemandx
interactive x
intellidemand
smartass
interactive
conservative
smartass 2v2
performance
along with ondemand and user space from before.
thanks

Good to hear....u will need to try different settings as each evo will be a little different...ie.. some can take alot of overclock and as u said when u went to high it locked up......my evo likes min 245 and i dont go very little over 998...mine does not like high overclock....i run between 768 and 998 or until i can see a lag or slow down in performance..depends on which rom i am running...i like ondemand x and smartass 2 on my evo but there is a good read in papa smurph's smurphed out v6.6 thread in development on governors and such...go to post #2....i wish there was a perfect setting i could give u but u will have to see what your evo can take...part of the fun of android.....carp

Governors
Thanks carp. I guess experimentation is the only way to know. i charged my phone last night ad i noticed that it does take alot longer to go from 100% charge to 90% but i also noticed that the phone temp was at like 110 deg F and a voltage around 4.263 or so. i have read some thread where they claim its bad for the Lithium ion batt to be over 4.2 V but as soon as i unplug it it drops to 4.1 something usually. I am using battery indicator app to measure it. i am using the underworld w/sbc kernal currently but the voltage being higher has me a bit concerned that i am damaging the battery kind of like pumping water into a jar with the the lid on tight til it bursts. Or in the batteries case - too hot i guess or until it plates.
