*Added a setting for charging that is 100/1400 conservative with a priority above everything except the heat one. so like 91 heat and 89 charging.
Seems stable, zippy and doesn't kill the battery too fast. All good.

UPDATE: the settings above worked a treat for me on froyo but after updating to gingerbread I found it was back to the old drawing board time. For whatever reason, and being fair to Samsung and gingerbread by saying that the tab is now older and been used and abused its whole life, I wasn't able to apply the same level of undervolting without lockups and rebooted.
Why? Well could be a few reasons, the one mentioned above I really think plays a part in it. I also think though that gb is just different. Obvious I know but I mean its different at a base operating level. It needs new bootloaders and as alot of the experienced developers currently doing the tab gb stuff I think are finding its got a few curveballs its very happy to throw into the mix. The other point is that the control app has been updated dramatically with new ui and a more polished look to the outside which I think also follows into the coding. Xan, the developer must be a very talented individual and is pioneering the CPU control at kernel level IMO and really deserves our support. You can get the fee apk but I think its worth a donation just for the free version.
I notice the newer kernels are also having preset UV settings which is awesome. Gives you a base to build on and as each tab is different, yours may not go as low in volts as little Johnny's tab but it may go further than big Bob's one, it provides a good starting point. Or whatever..

This guy is my favourite developer evar! Very friendly, very talented and shares <3. Read this thread as much as you can, its brilliant and has a few gems hidden in the posts. Also the kernel's are basically on the cutting edge. Its this guys patches that find their way to other, and all I'm pretty sure, kernels and roms.

thanks a lot buddy ! I was really looking for this !!!!!! you're my hero !!!!

Your most welcome mate. Any issues make sure and let me know through this thread.

Ps. Watch how big a difference it makes to battery drain with screen off and below 30. I keep thinking it will die before I get a charger and like 4 hours later its only gone down by about 10 percent.
As always, support the Dev's if your able to. They richly deserve it and it doesn't have to be much to make a difference. )

there is a problem regarding those settings. did you try to restart the Tab after? mine doesn't start at all ! I should try several times to keep pressing the power button and then, after few minutes it starts again. after uninstalling the Set CPU and Voltage Control, everything comes to normal.....any advice?

SetCPU seems to be very crashy on the SGT. You might want to try not decreasing the voltages quite as much, some CPUs can't cope with it. I've got mine set even lower and I'm fine.
The "performance" governor locks the speed at the "max" value, the "powersave" one locks it at the "min" value. It's a pity that the "Ondemand" and "Interactive" governors seem to be so unstable as either would be better for performance than "Conservative".
I've also got another profile for "Charging" which ramps everything up a bit.

One thing I have noticed after spending some time in here is that all SGT's are not created equal!! I have no issues with the settings above, none at all. It boots fine, runs super fast with 2200 being the average score in quad. And I am on my second day without charging... its been lighter usage but still....
I guess I got lucky but all I can say is trial and error, or search for a simillar problem with another user and ask what settings if any worked for them. My thinking is that there would be batches that will run one way and others that won't.

Its the CPU. They all have different tolerances on the minimum they can run at. Samsung just uses a voltage that guarantees all of them will work at. I've decreased everything 800mhz and up to -200mv. So far so good.

Try install jus UV & set the limit to 1400ghz. Run it for a day or two.
I have problem with SetCPU, give up on it. So now i only have UV installed.

thanks for the settings, no problems since 1 day

Sorry for stupid question, Am I need to flash kernel for 1400ghz? Or just use SetCPU with overcome 1.0 karnel?
Since there are some karnel said they are for 1.4ghz so I am confusing on it, tks!

If the kernel does not support >1ghz, then setcpu cannot set the speed to anything higher.
The overcome kernel supports an overlock of 1.2 and 1.4Ghz.

Overcome Kernel 1.0 is an overclock kernel. Just install setcpu to oc

with the settings above do you have it set up as "Save as boot settings"? i had set mine at bfq and limit clock to 1200mhz and not changing anything else saving it as boot but when i went to restart the tab it got stuck on the Galaxy Tab screen, i had to re-store my backup in order for the tab to re-start.
also how did you get the 600mhz:?-100=?mv?
i am using richardtrip's [Kernel] [EURO] [1.4ghz OC/UV] MCR EXT4 compatible/Voodoo Sound V15 22/02 hope that helps with what i am asking.

I gave up on Set Cpu and switched to Cpu Tuner, a choise I don't regret at all.

Recently changed to overcome kernel 2.0 and have changed to bfq. All stiull running smoothly.
And yeah i have mine all set to set at boot.

Thanks! Was looking for this.

I copied your settings to the last detail (bfq scheduler) and my Tab is crashing.
Now I am trying with lower UV.

Sorry buddy its been ages I should probably update this. I find that overcome has gottan alot better I still use the same undervolting but no profiles on set CPU. Just set to 100 min and1400 Max ondemand. I can use bfq and have no issues but one thing I know for sure, and I think it was even stated in this thread, no 2 of these are the same... same deal with more strain on the CPU than others so if my settings didn't work for you I'm sorry for that but all I can suggest is what I did to find the right setting... experiment, trial and error...
Best of luck,
Nobleskill

I found out what I did wrong...on Screen Off profile I didn't set "Performance" scaling, instead I did "Conservative"...the Tab was only crashing when screen was off!
Now that I switched it to performance it works just fine...
Using Overcome 1.4.2...
What's has better battery life, now that you have experience with both, with the profiles mentioned above or "On Demand" with no profiles?

That's a tough one as I use my tab a whole heap more and for many more things. I have 3 times as Widgets and so on... put it this way I used to get 2 days with low to moderate use on the setting in this thread, now with extremely heavy usage, I'm talking 8 hours or more almost straight with web browsing, ebooks, video, music, news ect...
I like my new set up cause its alot easier to configure and I find the most important aspect to battery life is the undervolting... overcrowded seems to handle the just fine. The only other thing I really swear by is an app like juice defender or battery boost.. set them up and its turning things off when not used which can be massive...
Hope this has helped and I'm happy to hear you sorted the crash issue.

Battery Life Suggestions - Please Post SetCPU Config's Please

Good Morning Thunderbolt Community:
I am looking for the best way to extend my battery life, I have a 2750 Extended battery and still only get a little over a day of battery life. I've read that some folks are using SetCPU again, and would like a thread dedicated to those who want to share their settings to benefit others....
Thanks in advance...ChiefDroid (a.k.a Chiefd23)

Running chingys 3d rom runing set cpu st 1113 max 368 min no profiles and st the end of my 12 hour day I have 70% left. have any more questions lemme know

Liquid gingersense 1.6. Imoseyons 3.5 kernel on extreme mode. Verizon 2750 battery. I get 50 hours easy with a lot of phone usage.

Gingeritis 3D beta VI, ziggys kernel set at 245/1.344 smartass gov, with script fusion (set cpu can be a big no no with some kernels, and id rather use scripts anyway) . I get 20+ hours with average use on a stock battery.

Pureasoptheory 1.3x modded imo kernel (stock with rom) setcpu at 1222/245 interactive and a profile for less than 30% @745/245 avg is around 24 hours on stock battery with low to moderate use, maybe a couple youtube videos lots of texting a few calls and lots of web browsing.
Edit: about 50% of the time I'm on wifi vs. 4g to clarify.

M0N0LITHTH3ORY. 245/1024 extreme battsaver. Standard battery. Lucky to get 8 hours. Best battery life of any rom for me so far. Average an hour of calls, 100 texts, TweetDeck and friendcaster pretty much every hour, words with friends, and web browsing.

Hack3dao5p by dhacker29. 12 hours and I'm at 80% NO UNDERVOLTING. I will undervolt with vipermod tomorrow and report back. Don't use setCPU. Use vipermod or speedtweak. I recommend vipernod for more control.

Just plug it in every night. I can get 2 days out of my extended battery but what's the point??? Have fun with it instead of worrying about getting more than one day of battery out of it!

I think I might make the switch! How much use? light, mod, heavy?

M0N0LITHTH3ORY straight out of the box, I'm getting close to 20 hours with 20% left for the first time ever. 4g when I'm out and WIFI at home. Like I said in the MONO thread this ROM is the best out there. oh yeah stock battery too. Thanks DT!

This is by no stretch of the imagination an Android development thread.

Fits better in General. I've moved it there.
Continue.

I haven't used SetCPU on my Tbolt in a while. My config is in my sig and my settings are implemented through ScriptFusion. The following is the settings I'm using in ScriptFusion. The first image is the clock/voltage settings, the second image is time-in-state. As you see, it spends most of it's time sipping .8 volts or less. As long as I'm not tapping glass like a mad man, eeking out a full day on the stock battery isn't terribly difficult.

Mod-heavy mostly internet jtexting and Facebook with a few phonecalls here and there. GPS off

i use gingeritis 3d, wifi when im home, and when im out, i only activate mobile data if i wanna check my fb or look something up. cpu is usually max 1113600 min 8064000 scaling powersaver, i also use chainfire's nightmode setting when im not actively using my thunderbolt (tested today and seamed to help alot), auto brightness on. at the end of the day on a stock battery i am usually at 20-10%

I flashed the newest radio turned off 4g and am running CL3ANTH3ROY and i got 20 hrs on the charge off of 1.0. Im on 1.1 now at about 14.5 hrs on mod/heavy use with a little 4g use in there.
I know if you do not have 4g in your area all the time turning that off is a MANOR battery saver. If you didnt know go *#*#4636#*#*phone identity, scroll down and choose cdma auto (prl)

I charge mine every night and it makes through the whole day no matter what I throw at it. I keep email on push notifications and gps/sync on all the time. 4G is on all the time. None of those are ever turned off.
Why? Because that's how smartphones are supposed to be used! It's not a marathon race.

Can I just make a quick comment about freq_min, freq_max, and governors? I like to equate them to a car's engine. At idle (freq_min), it's should be just loafing along, doing the least needed to keep things going. At red line (freq_max), it's chugging down the fuel and kicking out all the horsepower possible to haul that ride down the road. And your governor is kinda like your cruise control. You're cruising across Nebraska, not a hill in sight (you're phone is doing nothing) and it's just BARELY tipping that throttle in to maintain. But, you hit Colorado with those big ol' hills, and now it's flooring it, letting off, then flooring it again to get over those hills. Think of those hills like you making your phone do stuff.
Here's my point:
When you set your freq_min to 800MHz with, it's like running your engine at 5000RPM, all the time, regardless of load. Setting your freq_max at 800MHz is kinda like jamming a stop under your throttle so it will never make enough power to pull you over those big hills. The idea of a governor is to throttle the speed up and down relative to the load... kinda like your cruise control. Some could do it better, some have very limited real-world application (performance and powersave), and some are pretty much ideal. It really depends on how the dev has set them up or how you've tweaked them.
I post this because I'm looking at some of the setting some of you are using and I KNOW they could be more efficient. I would encourage you to look at your time-in-state and experiment with your freq_min, freq_max, and gov. As you can tell from mine, though I have my max set at 1.49GHz, it spends VERY little time up there. It's more like the nitrous shot if things get real hairy and the system needs the extra power.

i currently use BURNTH3ORYX V1.5 w/ the MR3.5 (802) radio, also have the 2750mAh battery, and i just use the built in "performance" option. I set it to 'OnDemand' and overclock to 1.5 Jigga Hertz.
for example, last night the battery was at 100% and decided to watch the movie "Return Of The Living Dead" all the way through. when it was done, the battery was at 95%.

[STATISTIC] [USERS NEEDED] Miui battery drain problem

Woops wrong category, sorry ^^ Please move it to general

Hey guys,
as you can see, I´m back And it´s my first target to fix the massive battery drain on Miui. The first thing I do is to compile a new kernel for Miui, but I need your help, too.
I have to locate the application that uses the battery most, so please go to Settings -> System -> Battery Settings , make a screenshot of it and post it in this thread. If you have the time to, please use Spare Parts, too and also make a screenshot of the battery usage.
Thanks for your help!

Advice on battery life, Beans 14/lean kernel

Hey guys, I'm new to this forum but not Android Central. Anyways, I just recently switched to jelly beans build 14 w/lean kernel. For some reason my battery life is just terrible. I'm just barely making it through an 8 hour workday, and that's not even using it that much. I was wondering if you guys had any tips for good battery life on this ROM/Kernel combo. I do have set cpu installed and running but I'm only Overclocked to 1.6 and undervolting by 50 mv. I also have a save battery life profile that drops it down to 1026 when the screen is off, it's charging, or battery is below 40%. Can you guys give me advice on settings to use to save battery life? I really like this ROM and kernel but I'm getting such terrible battery life. I think it's probably more user error than anything but maybe you guys could provide some tips.
Thanks in advance.

How recently did you switch to Beans and LK combo? I wouldn't base battery life off of the first day after a flash. I use the same combo, however I use the LK exp version. I would suggest changing your voltages to match begin at a lower mv. I have mine starting at 900 mv according to Imoseyon voltage chart.
http://rootzwiki.com/topic/31329-ke...nimalistic-kernel/page__st__1410#entry1042976
That said, I have my screen off max cpu speed at 486 so you could probably go lower. How's your signal at work as well?

Hey thanks alot for the response!! It's the third day of this ROM/Kernel combo. So I can really go as low as 486 when the screen is off? I figured it probably wouldn't be very stable if I dropped it that low. I've looked at the Rootzwiki thread you posted and have set all my voltage settings as follows for the last two days:
1900mhz-1250mv
1809mhz-1200mv
1720mhz-1200mv
1620mhz-1150mv
1512mhz-1100mv
1458mhz-100mv
1350mhz-1125mv
1242mhz-1125mv
1134mhz-1125mv
1026mhz-1125mv
and its 1125 mv the rest of the way down.
So basically I'm undervolted by about 50mv at the highest clock speeds, then gradually come down to about 25mv at the lower speeds.
I'm really scared to go much more than that for fear of causing instability. I would love to be able to undervolt by more if I knew for sure it wasn't going to make it unstable. What are your voltages at the highest clock speeds and the lowest? Can I undervolt it by more when I get down below 1026 mhz? I figured they were all set to 1150mv stock for a reason. Got any advice on that? I want to squeeze as much battery as possible..
Oh and my signal is perfect! I think it's even better than it was before. This Rom didn't come with a different radio too did it?
Thanks for the reply!!

I actually have my voltages set to exactly what Imoseyon has listed for the nominal cpu. As far as my screen off, I honestly just picked a low number and since I don't see lag I keep it there haha in addition, I use interactive governor which scales up the cpu once the screen comes on so it balances out either way.
To check which cpu type you have, do this. Details on what the cpu differences are included in the link as well. Matching your cpu type and adjusting your voltages may help extend your battery life but some say it is marginal.
No, your radio actually stays the same unless you manually flash a different one. I should also ask, what else do you have enabled? For example, in Maps/Settings, do you have everything disabled except "Enable Location History"?

Yeah i already did that to sort out what Cpu I have as well.
And I have limit background processes enabled in developer options, limit processes 4 at most. Also where exactly are the maps settings? I have GPS off and Google maps frozen by Titanium backup (except when I use it occasionally). I also have every other unnecessary app frozen. Like the Samsung keyboard (use swiftkey) the stock email app, etc.

Well it's under Location Settings but if you have Maps frozen until needed then it's an unnecessary step. You have done even more than I do or suggest haha I haven't frozen anything.
What would you say you're seeing as your average screen on time?
Sent from my SCH-I535 using xda app-developers app

Oh average screen on time is probably around 2.5 to 3 hours or so. Nothing crazy. I just wanna get my battery life back to before, where basically I could leave home fully charged and work a 10-12 hour day and come home with around 30% or so battery life. That's good enough for me.
So about these recommended voltages. I have the "fast" processor, should I just st the voltages for what he recommends? Are those recommended for bet battery life or best performance? I want to undervolt as much as possible without creating an unstable system or causing damage.
And can you help me understand the governor settings, my understanding is that "ondemand" activate both cores when needed, and interactivex is all the time? Is that roughly correct?

Okay nevermind about the governers. I read quite a bit more about them over the last hour and feel that I understand them at least a little bit better. hehe. So much to learn!! It seems InteractiveX is the obvious choice for performance AND battery. I'm still kinda unsure about how much undervolting I can really get away with though. I love how smooth everything runs when I'm overclocked, but i'm not sure it's worth it in terms of battery life (unless I'm playing a game, or flying my AR Drone). It seems there is still an advantage to be had by setting it to the normal clock speed (1512mhz) and then undervolting by just a bit. Might be able to squeeze just a tad more battery life out. It's still nice to have these things within my realm of control though. I understand why people find this so addicting now!

Yea flashing kernels and roms is very addicting. Since you have a fast cpu, you can actually UV much lower than I can with my nominal cpu. You can set your voltages to match Imoseyon's table and you'll be fine or maybe try lower. I know from experience that I can't UV lower than 900 mv without my phone immediately locking up lol You can even hold off on setting voltages at boot if you want to get a feel for performance while UV'ed.
I can't really speak on OC vs. regular clock battery life, I keep mine OC'ed at 1.62 ghz so I'd notice minor drops in battery life compared to say 1.8 ghz. I don't even have much need for that since its fast enough to me as is. I haven't noticed too much of a hit on battery, I still range between 2.5-4 hours screen on pending if I'm on LTE or wifi during that charge.
Also, if you want to try your hand at really digging into kernel settings then you should also check out the the Team Kernelizer's thread for KT747 kernel. Personally, I use LeanKernel cuz it works really good for me so I applied some settings from there but not everything was applicable. This thread has some really knowledgeable people in it. Definitely give KT747 a look, or any other kernel for that matter, and see which ones you like the best.

Yeah i think i may have had a bad battery. I checked and I know my phone is deep sleeping, but since adjusting my voltages and settings last night it'd definetely improving. I have my voltages set to 25mv under what is recommended on that chart down to 1.4 the in the lower clock settings o have it exactly at the recommended settings. Seems to work okay. I have set on boot enabled but i also have the stock voltage settings on my SD Just in case of a boot loop.

Does anyone have any suggestions? I really like this ROM and would prefer to keep it if possible but this battery life is terrible. Ant ideas on some measures I could take to try and improve it a bit?
I wiped cache partitions, davlik cache, and did factory reset before installing. I even do them twice just to be sure.
Would maybe wiping and re flashing the Rom help? I'm totally stumped here.
sent from my Galaxy S3 on beans 14 via tapatalk 2

I don't understand. I used cpu spy and i know phone is deep sleeping. I have set CPU to drop the clock speed when screens off.
Why the heck is it using so much battery? I'm dropping about 6-7% battery at idle. Somebody shed some insight.

Recommendations for kernel/ROM with good battery life

Hi,
I switched from my Galaxy S2 to a Note 3, and I'm immediately running into serious issues with battery life. After switching to low-power mode and after reconfiguring my SetCPU, I get about 16 hours with screen off and Wifi on. So, time to switch ROMs, and looking through the forum, I am unable to find any kernel/ROM comparison based upon battery life. Therefor would like to hear recommendations.
Have been looking at the X-Note, but besides a remark to pick the X-kernel for battery life for the v8.0 version, I am unable to find any info for the v7 JB version.
Looking forward hearing your experience.

X-Note is a good choice, X-Note is one of the reasons why I bought a note 3(Since he was developing for note 2 first but went over to the note 3). Changing DPI is manditory for me. Default DPI is for my grandpa so he can read the screen without glasses -.-. Batterylife is quite good for me. Haven't reached 40% after a day yet.

Thank you for the info. May I ask which version you're using, the JB (7.0) or KitKat (8.0)? And, what is the X-Note Transformer compared to v7.0?
And, most important, which kernel are you suing?

Mate if you are getting 16 hrs of screen off time and no screen on time, it is not a Kernel/ROM problem, you have a rogue app installed which is causing your phone to be constantly awake and draining battery.
Definetly go for the 4.4 since it updates to KitKat which offers many benefits. There are also slight improvements in battery life.
As for the ROMs I've tested all Custom ROMs and honestly it's about preference. Check the additions they provide and decide what's best for you. I'm a battery nut and believe me none of the ROMs add any actual benefit to battery life over stock for 4.4.
Personally for me, since I love a lean install and don't like that much modifications I found Stock Samsung 4.4 works best for me. I just use ES file explorer to debloat it from all the apps I don't want and procede to installing the apps I use I've found that you can expect around 6.5 hours of on screen time with auto brightness +5 and no rogue apps (no apps that require constant gps syncying and what not) spread over from 1 to 3 days depending on how you use your phone. That is light web browsing, chatting and movie watching. Games will suck your battery dry like space fuel on the Note 3.
As for the Kernel on the 4.4 bootloader you don't have a lot of choices. Afaik the only ones available at the moment and CustomN3 and FlexKat engine. Considering you are asking for battery life I'm guessing you are more interested in power perserving than overclocking. I would go with FlexKat since it supports intelliplug and intellidemand gov. Actually I am testing it at the moment my self. I get 1k more points in AnTuTu using intelliplug and intellidemand compardd tl Stock Kernel. Seems pretty smooth and stable for now, haven't run in any issues but I've only been uskng it since last night. Battery usage for now is 35%, with 2.5 hours of screen time and over 16 hours of total since uplugged. Can't really compare to Stock Kernel yet but it doesn't seem like there will be any major difference.

I tried all roms actually, But nothing suited me. Till I jouned x-note. From x-note 7 I waited till 8, and installed it the same day it came. 8 is super stable, havent had problems(except for some apps which arent compatible with kitkat).

Thanks for the feedback, which I highly appreciate. I must admit being kind of a battery freak too, and I like a UI to be simple and practical. My golden rule is that whenever I carry the mobile in my pocket, I don't care about speed. Just keep them as low as possible in order to keep running stable.
When I look at what's draining the battery then at the top are Cell Standby 18%, Android OS (4.3) 18%, Device Idle 11% and my K-9 email app which stays active 11%. And these numbers are with low power mode activated, and with SetCPU setting minimum frequencies with screen off (the stock kernel doesn't allow for a voltage configuration). When staying with the same OS 4.3, I may be able to improve this by maximum 30%, in going from 1.2V to 800 or 850 mV in standby.
I'll give the X-Note 4.4 a try, and using the X-kernel may then also be beneficial. Will report on the result.
Thanks

Sweet Rom for the stock-look custom rom, battery life is great!

That's a 2nd one on the list. Can you please be more specific about the battery life? How does it compare with what was mentioned for the X-Rom?

Wanted to do the flash and ran into a question. I downloaded the Poland KitKat official ROM, but the poor thing is only 3 MB and when I try to open it, both windows and winrar, I get the message "unknown format". Is it maybe only a patch that's applied to the 4.3? But then I should still be able to open it. Any advice?

Got it resolved. Only the MIRROR seems to give a reliable download.

Also try my battery saving tips here! Good Results!
