Colin battery tweak for evo

I liked this battery tweak when I had my hero. Can anyone make this or is there another way to do this with set cpu. I messed with the profiles
But two confusing for me.

Just so i know, What's that ?

Its a battery tweak that was made for htc hero. It would under clock when certain criteria were met too save battery.

Yes but collins tweak had other modifications done to it that Setcpu does not do. It was actually a lot smoother and saved a lot more battery than setcpu

tasker could do most of it i'm sure.

Set cpu looks like it can doo most of it. But for newbies colin battery tweak was so simple. Can anyone tell me a good setup on set cpu

Avs will do alot for you. Get a kernel it Avs.

just get a cfs kernel and setcpu. thats basically what that tweak was...

I have snap bfs. It plays better with my phone. And with snap turbo it is lightning fast .

Only to be used with CM6 right? Too many non-working things in CM6 for me. I love cyanogen but I don't know why they would develop a rom for an Evo with the most important thing missing, it's 4G capability!

collin battery tweak has a script with a ton of commands thats change more then what setcpu does. It was mostly made for cyanogen mod, with swap, and bfs kernel. Then from there it has changed and added alot more features within the system/kernel.
I was helping out with the scripts and testing in the very beginning stages. There is actually some of the commands you can change to increase performance.

is anyone working on it for the evo

Because CM6 is for more devices than just the EVO. Before 6 final came out a lot of the coding was meant to cover a wide variety of phones. Now that 6 final is out coding is being focused on specific phones such as our EVOs. That and because, honestly, there's way more people in non 4G areas than there are in 4G coverage areas. Don't you worry. They'll get 4G working on CM eventually.

What am I doing wrong? Battery life from hell.

Well I'm using juice defender I have it on custom with basically everything checked. It claims I'm at 1.75x battery. I'm on Aokp with faux 10r2 kernel. I'm at 1.06 ghz interactive. I'm now under 50% battery with barely an hour screen time and like three hours phone on. What am I doing wrong this has never been so bad.

Try franco kernel build #11...works great for most...im averaging 18hrs with 3hrs of screen time (all this with a stock battery)

Sounds good but I thought his and faux kernels were basically the same but faux gets better battery?. I've noticed my phone doesn't ever really deep sleep either.

Never understood how some people think that adding another constantly running app in the background will somehow net them better battery life...

3g shuts off when my screens off. I fail to see how that cant save me battery. Also juice defender is using about 1-2% battery.

Quick question regarding the Franco Kernel...
Today I flashed to the latest version along with AOKP - seemed to be a good mix till I went to make a call and realized any call I made/received dropped in a matter of 3 seconds lol...
Does that sound like a kernel issue or possibly the rom? I had enabled power saver so wasn't sure if that may have done something...

Are you on a cdma or GSM phone? I have this combo on cdma and I'm fine...

CDMA... Not sure what caused what- using the 4.03 radios..

Peeshiz. Go into from control than the bottom to performance. Its in there.
And wil trying going back to the old radios.
Sent from my Galaxy Nexus using XDA App

im sorry, please bear with me
but where is the control option?
EDIT: oh do you mean in the updater app? because i dont have that app, so is there any other way?

constantly running app is not useful at all. It may drain your battery

Don't worry man I'm patient. Go into your settings for the phone. So for stock aokp go into the app drawer and go to the settings "app" the first thing on that list is rom control. The second to last thing in from control is performance settings.

Regular CPU Settings or Reduced CPU for Battery

Does anybody know if having the normal settings are better or under clocking (say 1Ghz) for battery for this particular phone?
I also know that a higher speed can perform the calculations faster and thus save power. But, I'm just curious if there is a sweet spot.
Sent from my SGH-T999 using xda premium

Have you tried under volting, by using a custom kernel. Word of warning not all CPU built equal.
Sent from my SGH-T999

I'm using Faux's kernel which had reduced voltage setting already.
I'm just curious.
Sent from my SGH-T999 using xda premium

The best way to really tell woukd be to step the max freq. down by one or two and run it for a day or two. If it runs stable and you don't notice any issues you'll prob be good to go. My guess would be running between 1.2-1.3ghz would be a good spot.
I'm honestly not sure you'd see much difference in battery though since its probably running much slower than that most of the time its not sleeping anyway.
Plus I think I remember seeing somewhere that the power used to run at 1.5 is the same it uses to run at 1.3.
If your going to see improvement in battery its more likely you'll get that from voltage adjustments and your governor choice. You'd probably be best served by reading through the kernel thread to see what others have tried and reported.

[Q] Questions about kernels

I'm new to Android. I made a few posts on here making that abundantly clear (lol). I am just wondering, what exact part of the OS is the kernel? For example, I'm using LiquidSmooth with the default kernel that was included with that. If I were to flash the ktoonsez kernel, what changes would I see? Also, could someone point me to a site where I can download the KT kernel for LiquidSmooth 4.2.1 JellyBean Beta 2? What other kernels are there? What are the advantages of using them? And finally, where can I find them?
I'm looking for a way to conserve battery life right now, but not take away from how my phone currently looks. Sorry for asking such a stupid set of questions, but I'd like to know about this since I plan on sticking with Android. And if that's the case, I wanna learn all about the neat things I can do to make my phone customized, sleek looking, and effective.
Thanks in advance for helping out this new comer to the Android scene

The kernel is the interface between the devices software and hardware. Its basically a bundle of drivers and code to tell the hardware and software how to communicate. All computers use a kernel from windoze to OSux and Linux. Android is based around a modified version of the Linux kernel. You won't see any visual changes when you flash a kernel. And you can find em here in the development or original development sub forums

Cool thanks for the detailed explanation. I never really took the time to look up the exact purpose of kernels in an OS but you just explained it to me perfectly.
So, are there any kernels that are better for say battery conservation and performance?
Sent from my SPH-L710 using Tapatalk 2

That all depends on your settings and usage. Theres no one way to get the best battery and performance for your usage, mostly just trial and error trying out different settings and tweaks til you find what works for you. For a good battery performance balance undervolting and overclocking work well. For instance I'm on a note 2 and im overclocked to 1.8ghz and undervolted by 75mv across the board and get almost identical battery to stock, however I still gain in performance without sacrificing battery. Now if I drop my clock rate back to stock and keep the undervolting I get same performance as on stock but my battery life increases by a few hours.

Awesome, installed the KT kernel and used the settings listed in the Kernelizers thread. I also installed DS Battery Saver Pro and now my battery life is amazing. Left my house at 7:05AM this morning and on my way to work over the course of the hour my battery dropped 3%. Usually, my battery would drop 10% - 15% during this time so I am VERY happy with the outcome.
Thanks for all the help guys

Kernel inquiry

Ive been working(slowly due to work) on a kernel for the lgog. I've been able to do some pretty heavy overclocking but I need some community preference.
Overclocking obviously causes more heat and reduced battery life. Higher overclocks require overvolting beyond required to maintain 1.5ghz set by Qualcomm/lg. Keep this in mind before asking for 2.0+ overclocks in daily kernels.
What top clock are you guys wanting for a performance kernel? Also are you guys interested in a reduced clocks kernel. 1.0-1.2 top clock with a lowered low end clock along with lower GPU and system clocks.
Personally I Dont see a big need in heavy overclocking on a quad core. However I would like some opinions before I release test kernels. I will attempt to see just how far the lgog can go at least once, but that will take around 10-20 test kernels to find the top speed.

I like the idea about under clocking. This bad boys fast already. The battery savings would be nice.
Sent from my LG-LS970 using xda premium

The highest overclock that I would like to see is around 1.7-1.8Ghz even though I don't know what I would need my phone running that fast for. Now the under clocked kernel sounds very interesting .

Just looking at how this governor uses CPU, it hardly uses the middle ranges. Maybe some better governors? Just another thought.
Sent from my LG-LS970 using xda premium

I would be interested in a kernel with A 1.8 top speed slightly lower bottom end and different governors. While 1.5 is fast 1.8 with a better governor along with a 128 minimum speed would be a good comprise kernel

I don't know of anyone having speed issues to warrant an over clocking kernel, seems more for bragging rights.
I think most people would want a kernel that saves battery but doesn't compromise on speed. Also, have you looked into the wake lock issue yet?

I'll probably use faux's volt control. This is my first Qualcomm kernel so I've been mainly running through it. The n4 is far far far cleaner. Our source is a jumbled mess to an extent.
Also the other devs have found a way to run n4 stock ROM with kernel. However finding the best way for everyone to benefit is being sought after.
