Setcpu or JD

Very general question. I'm on 2.3.4 4.5.91. unlocked rooted. cam Does anyone use setcpu or JD on this release. It seems as if settings has some battery controls in it. Just curious. Thanks

If you are overclocking, SETCPU allows you to control clock speeds with profiles and set lower CPU operating voltages to save battery.

See here for some undervolting info:

I have not found any software like JD that works on gb.

forgive the noob question, but what is JD?
i use SetCPU, bought it off the market (gotta support our devs, right?) and i'm LOVING it. it does everything i need for managing my CPU, i have custom profiles setup for all sorts of situations, and undervolting gives me amazing battery life. when i'm running Ninja SF, i can use my phone for 25-30 hours without charging (moderate use, no hardcore gaming or music)
but on CM7, i can unfortunately only average about 20-25 hours of battery life with the same use.

JD = Juice Defender

Hmmm ok. I'm on stock not over clocked. Setup may not do much for me. Juice Defender could control the radios. But settings seem to have some battery options for extending battery life.
I didn't know if setup since I am rooted would at least help with scaling and throttling down processor speed when battery reached certain levels. I'm sure these would help on a custom Rom.

Best Battery Life?

I have two HTC EVO 4g phones with CyanogenMod 7.2 RC1 | Tiamat_Evo-v4.1.0-sbc (CPU governor: Smartassv2 245/1152). They are also running SuperCharger v6 script for memory optimization. What I'm looking for is optimal battery life, stability, and not very much focus on performance. Already searched Google for awhile and the answers were never clear and led me nowhere.

Bump. Also need a mod to move this to Q&A.

Well you might as well underclock; no need to be over a 1152. Additionally, play with undervolting to see how much the evo can take. Keep the radios off when not needed.

I'll do some underclocking, but undervolting seems kind of sketchy. The kernels are already undervolted.

+1 for undervolting and tiamats kernels are not undervolted by default so go go vipermod lol
what kind of battery life are you getting now?

IncrediControl or vipermod? I don't know what kind of battery life I'm getting since its my parents phones. I'll try undervolting out, but just want to know if the app is safer or the script. Your only supposed to go like -50 under for both right?

Personally, I'm having fantastic battery life and performance on Swagged Out Stock N (thats the one with go launcher, and not sense), aggressive lionfish 1.8 SBC, plus using setCPU...

Ok thanks man, yeah I ended up using vipermod -50 and underclocked the phone smartassv2 - 128/652. Working out great so far.

I'm a super heavy user and have tried all the big name roms, but none of them gave me the great combined total of speed and battery life, I get bewtween 15+ hrs other roms I got normally 6-10 nitrous Rom with underworld kernal and uv'd via vipermod using extreme mod, and still runs fast and I'm oc'd to 1.03
This is a picture of what I consider normal use, heavy I consider screen on all day, normal is like 3 hrs of Pandora text here and there played games probably for about an hour total, phone calls, surfing forums, using gps results:

This worked for me. Thanks

I've had a lot of bad experiences with aosp roms... GPS not working, poor data connection, and "cellular standyby" taking up an obnoxious amount of my battery... I've tried CyanogenMod and deck 1.3 with savaged Zen and tiamat kernels
Maybe I just have bad luck?

The screen is what drains battery so much and yours was barely on =p

Battery Saving Apps (4.0.4 Aurora ICS)

Hi there many of you have thought about battery saving apps.
Do they really work?
Are there some apps that instead of saving battery just drain your battery even more?
Do you know any methods that really save battery?
Just post your oppinions about this subject.

Battery saver apps are useless. just turn of data, sync,WiFi, Bluetooth when not in use. decrease screen brightness and screen timeout to 30 seconds. Use 245-806 with ondemand goveror for better battery.

I've read many people saying that using the ondemand governor wouldnt save that much battery because of the continuous search for cpu activity, actually i'm using performance at 1024 and i also have another profile with 806 performance aswell.
I have to test it better in order to see which governor saves more battery.

I think a good set may useful

I used to use 806 on demand, 1024 ondemand and 1200 ondemand... now I'm using 1024 performance, and I dont see any battery difference.. damn thing still drains.

The battery lasts 4/5 days on idle, what more do you want? It's par for the course.

why do you need the phone to stay on idle? for that you could buy a 10$ one =S

Because it's an indicator of battery performance and proves there's nothing wrong with battery life on Aurora, despite what many believe. Having ~1 day of battery life with heavy usage and 4-5 days (or even more) on idle is on par with the battery specs.

Actually we all know that the battery life in aurora its not full optimized. what i mean is what can we do in order to get the best performance without having to spend so much battery life. maybe its not possible but who knows

Fact: ICS produces more traffic than GB. A lot of apps (like browser) use more memory, so background processes die more quickly. You cannot except to get the same kind of battery performance out of an ICS rom and that's the end of it. This has nothing to do with Aurora.

When I dont need to use the phone I put the governor in powersave with a low Mhz and the battery is more safe with little use.
Phone become a little more slow but work.
When I really need to use the phone I change the governor to Smartessv2

[Q] S4 i9505 "underclock" CPU, possible?

Battery life on this phone is abysmal - on a fresh phone. Didn't restore much from titanium backup.
Would like to drop the CPU down a good 25% or so, can this be done without too much stress? It's an unbranded, rooted i9505 in Australia.
I suspect I'll need to flash something to do so, is that right?

It must be asked in Q/A Subforum buddy.

Define "superb" for me.

Apologies for jumping in here. Can you define abysmal too? I would say my battery life is more than double my S2 (that was Cyanogen niggtlies but this is currently djembey's slim). Biggest drain is usually the 3G but I have that off most of the time. It is hard to compare to be fair as we will all use different settings but I have a lot of the bloat removed or disabled, power save on and screen at half brightness. How is yours setup as maybe we can shyc settings a little to compare more closely.

If the reason to underclock is to save more juice, you should understand that the phone doesn't work on 1,9ghz most of the time, on average it's 200-800mhz depending on task, so you would not probably win a lot battery if you underclock let's say to 1.7 unless you're a heavy gamer.

I know this tread is already pretty old, but that answer is only partially true.
On stock configuration the GS4 uses the 'ondemand' cpu gouvernor. That gouvernor ramps up the cpu speed to the max when cpu activity is detected and will then slow down the cpu depending on the task. So everytime you open/close an app the cpu is running at 1.9ghz. (At least that I heard/experienced) using a custom kernel you can choose a different gouvernor which is more battery friendly, or lower the max cpu speed(from 1.9 To for example 1.7ghz). You can also lower the min cpu speed so that when the device is idle, it will consume less power (I think standard is around 350mhz and I put mine on 189). Some kernels even allow to underclock the GPU. Undervolting will also save battery.
In short: using a custom kernel you can really save some battery, increase performance, or get a better balance between the two, but you will have to take the time to find the settings that work best for you. I personally use KT kernel, with an overclocked CPU and GPU, but I also undervolted them both by 75mV, and with some tweaking with settings for when the screen is turned off, my battery lasts longer than stock configuration.
Correct me if I'm wrong on something, I'm not a Cpu expert
And sorry for bad english

Check this out, if you long press the power saving icon in the notification pull down, it will bring the settings for it, Uncheck all but the cpu. It will run no higher than about 1.3 ghz and is plenty fast for all tasks. I use that setting on the s4 and note 3. I never ran into any lag except TouchWhiz home launcher but I use Nova Launcher anyways.
You will see a better battery life as well.

Pokemon go?

Would this phone work well with Pokémon go?
Wanted to hear from players. Want to know if battery drain, GPS, heat, or GPU are issues.
I've read some conflicting accounts. Wanted to know if running MM stock would be fine. If any particular mods are needed.

Works well in my end. Stock MM w/custom kernel, no gps and gpu problems. Have battery drain though because my cpu governor is always on "performance", have 2 spare battery for the remedy lol. I Like my phone to have snappy performance downside is 4 to 5hrs of heavy use and gaming.

That's actually pretty good battery IMO. Is that on one battery? I'm assuming regular performance or even undervolt would be more that enough for pokemongo?
