Battery Tweak Epic Edition RC1

Plans for next revision:
*Add in Decad3nce's temperature control
*Bug nullghost till he gets init scripts running so we can have this startup at boot
This is really a tool for power users
If you don't consider yourself 'comfortable' with messing with your phone, then don't.
This is mostly the work of collin_ph, all the ideas are mostly his and I have only contributed in part to getting some things functioning correctly and some optimizations for the Epic.
What does it do?
This tweak creates a service that periodically checks the phone's power source.
If the power source changes, it reconfigures the device for maximum performace, battery and safety.
Tweaks memory settings for current power source
Re-clocks CPU based upon battery remaining or current power source
Reclocks for maximum performance if on AC power
Reclocks for maximum performance and charging safety if on USB
Reclocks for performance and battery if on Battery
As Battery life is diminished, Maximum CPU frequency is lowered
Tweaks scaling charactaristics depending on power sourcee
CPU Scales up less frequently on battery power
CPU Scales up more frequently on USB/AC power
The CPU is allowed to scale dynamically in all charging states based upon CPU usage
Includes a batt-cfg utility to configure the system
You may load 1 of 3 pre built profiles
Manually configure CPU Frequencies in all charging states
Determine the percentage of underclocking as the battery drains
Configure how often to poll the power state / battery statys
Disable batt.sh service from running at startup
Includes a batt-rm.sh uninstall utility
Includes a batt-diag diagnostic utility
Includes optional Disk performance tweaks (enabled by default)
The Tools
The entire 'application' is written in shell code and was first written just to give a performance and battery boost, but since has evolved more and more.
All the tools mentioned will be utilized either through the terminal, or in adb shell.
batt.sh
This is the core of the entire script. Don't mess with it.
The one thing you should do after installing the script:
Code:
Code:
pidof batt.sh
If theres any number showing up after it, then it's working fine.
batt-cfg
This is the 'main menu' of sorts, as it gives the user all the options and allows them to toggle tweaks/mods on the fly.

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
batt-diag
It's a diagnostics utility, allowing you or someone knowledgeable to figure out any issues that you may be having with your device and be able to pinpoint exactly where the problem is.
batt-diag -v gives a more thorough output as you can see here; http://pastie.org/1162034
batt-rm.sh
It's a battery tweak removal script, follow the onscreen prompts and it should remove just about any trace of the battery tweak script.
The Presets
The presets are just default configurations that I have set up that can make your phone more efficient without you, the user, having to manually set everything.
The preset of 800 literally means that 800000 is the scaling_max_freq, or the max frequency, that your phone can achieve after you enable it.
Just typing 1, and then enter, you'll be ready and set to go. Same with 2 or 3.
Customize Settings
This is only for the experienced user, and it allows you to manipulate most/ifnotall the configurables on your device.
Note, you do not need to configure anything to enable this battery mod. Default settings will be assigned at 800MHz.
All the settings explain what each option does, so read them carefully.
Disk Boost
Remounts via noatime and nodiratime. Look up what that means on your own, and why it benefits performance the way it does.
Prerequisites needed to run this
Phoenix kernel 1.48 with Epic Experience should run this just fine
If you're running any other kind of rom, feel free to try it but i cannot guarantee that it will work.
This script will WORK even if you don't have the import call at boot, but it won't survive on the next reboot.
You can check via:
Code:
Code:
pidof batt.sh
NOTE: This script will also prompt you to try to run itself as root if you use it in terminal.

*make sure you are running these as root*
*disable setcpu while running this*
*been reported as rom manager fc's after batt tweak, simple fix reinstall rom manager* - thanks for the tip Raiderep

Finally got that working

This is perfect. As a former hero user, I was thinking to myself a couple days ago "I wonder if anyone is going to port the collin_ph battery tweak," and here it is.
Thanks!

I'm about to head into work and I got this downloaded. I'll put it to the test for the day. Thanx for the port or whatever you call it, I had this on hero and loved being able to get rid of setcpu(which I never really liked) but still have something governing battery use

Is this compatible or even needed with the mix up kernel?

compatible? maybe as i said this is known working on phoenix kernel as for others i cannot say. needed? well that depends are you happy with your current battery life?

Using Phoenix kernel 1.48 with Epic Experience bogged down my phone after installing, im only at 76% battery life, i cant imagine how slow it would be at 20%
edit:
its fine now, i guess it had to load initially?

Whats the best settings you think we should run..for the best battery life

800mhz or you can use configure to keep that even lower... obviously the lower the cpu freq the less voltage it uses = better battery life

I just set this up to the 800mhz defaults. I will come back with results

How does this govern cpu clocking and usage? I'm assuming there's no live governer such as ondemand or interactive at play here?

phoenix 1.48 has a working interactive governor

So how does this affect setcpu? I'm runnin baked 1.3 ghz kernel..does this mean after I install I won't be at 1.3?
Sent from my SPH-D700 using Tapatalk

this is set for 800/1ghz/1.2ghz i included the configure option so people can make teh .conf however they see fit.. if batt.sh runs on it then it will scale from 1.3ghz after you configure it. witht he beta versions i dont believe anyone got it working on baked snack but if you try please let me know if it works what doesnt etc etc

when i try to run batt.sh i get this message...Mount: cant find /mnt/sdcard in /proc/mounts..what does this mean

its an issue im trying to figure out, batt.sh works fine without it, thats part of the disk speedups, in batt-cfg you can disable it

new feature will update tomorrow

not sure why but shootme is screwy for me recently as you can see. i have 0% tws, 37% voice calls at 30 mins 29s display is on for over an hour. screen is at auto, 3g, drm services RUNNING. oh yea im at 1.2ghz

Still have problems with this tweak...this is wat iam getting when I do batt-cfg I hit number one and I get this....
Loading 800mhz default
[: Bad number
Save settings...
Settings saved
Starting batt.sh
Note: when you exit ADB or terminal, you may have to hit
CTRL-C
Then my phone freezes and I have to pull the battery

[Kernel] [2/3/2012] BD-Ace Kernel [1.1.7] [Inspire-Based]

BD-Ace Kernel​
This kernel is my daily driver on my Inspire. This is also my first development effort on any device/platform. If it doesn't work on my device, you will never see it available here. I plan on having something that works smoothly, but is hopefully universal and appealing to a wide audience
This kernel originated from HTC released GB 2.6.35 source code for the Inspire4G -(Ace). It was initially build for use with ClearDroid Rom, but in the interest of FOSS its now for everyone
From 1.1.4 on you will notice two versions
"Safe" Version is to be used on release builds, the Maximum Overclock is capped at 1.3GHz to stifle hot CPU issues
"I'm a BigBoy, I'll do what I want" Version is exactly like "Safe", EXCEPT max overclock is set to 1.8GHz
Starting with 1.1.7 there will now be 3 versions
Safe (capped at 1.3Ghz O/C), BigBoy (capped at 1.8Ghz O/C), and WCH Rage (2.2Ghz O/C)
Install
Download, flash zip in CWM (Clear Dalvik), wait for first boot (sometimes takes a while), enjoy!!!!
Thanks to:
ClearDroid - Initial Encouragement, ClearDroid Rom
Erasmux - Smartass2 implementation

Questions
[Q] Is this a sense kernel?
[A] It is my daily driver on my Inspire using Cleardroid (A stock based sense ROM)
[Q] Will this work on XYZ super duper awesome rom?
[A] Maybe, try it and please post if it does or doesn't work
[Q] My battery life isnt as awsome as everyone else makes it out to be
[A] I personally have found that preforming a battery stats wipe in cwm and then a few dead/fully charged cycles seems to help mine out on reporting correctly.
[Q] Why do you really need 2 versions, with just the Overclock changed?
[A] I and some other users have had some random reboot issues while running at higher speeds. So, "Safe" is to help stop that for stable builds. See Here
[Q] But I dont like not having the maximum capability, let me have 1.8GHz
[A] Then download the current BigBoy version an have at it.
[Q] While trying to set my speed above a high 1.4GHz, my phone locks up......WTF
[A] To use 1.4GHz and up: 1st set your govenor to "Performance", the move the slider higher
[Q] What if I dont want call recording
[A] Dont install any app that records calls

What Roms does this kernel work with?
Confirmed to work -
ClearDroid 1.2.4 and above
CoreDroid
Doesn't work -
Any AOSP Based (non-sense)
Has complications with - /
BinDroid - Mic doesnt work on speaker phone
Energy ROM w/Sense 3.5 - Mic doesnt work on speaker phone
GB Sense 3.0i / Stock GB 2.3.5 - Video playback and usb settings
RCMix3D Runny v3.3. - No Sound out
Funzy ROM - No Sound Out
Any ROM based on DHD instead of Inspire. ~ There is just enough of a difference to cause issues

Score! Well done bro! This is my favorite kernel to date. Everything just... Works!

Yeah, Ill hit you up on talk

Has anybody from other ROM's tried this? Any feedback is great.

It's Saturday, I'm bored, so I downloaded a new kernel and tried it.
I used this on RCMix3D Runny v3.3. It works fine as far as I can tell, haven't done extensive testing yet because I have to make some dinner. However, the first thing I noticed is that the rear speaker doesn't work. No music, no ringtone, etc. Earpiece works fine.
Other than that, it seems nice and snappy.

Do you know if that is Inspire Based or DHD?

Sorry, I backed up to my previous rom. It seems that the microphone didn't work either. Couldn't use it.
If I have time tomorrow, I'll get the info for you if you still want it.

[APP]Voltage Control - control OC/UV for OC kernels

I take no responsibility for ANY damage / data loss may occur. Use this at your own risk. Beta quality software!/Alpha quality features!
The app has its roots in Samsung i9000 (Galaxy S) and i9100 (Galaxy S2).
Now its time for wider audience, I think its ready for use on many more devices.
Stats:
It has over 100.000 market downloads and over 50.000 active users!
I know its been posted elsewhere, but I've seen some similar apps posted in this forum, I think that my app is worth it.
ICS compatible
(lol ofc)

- saving settings to be automatically applied at boot (init.d script, startup service)
- save/load 1 profile (lite)
- Widget with profile switcher and app launcher (passive, little to no resources used!)
- well designed and highly optimised UI (I hope..)
- robust kernel detection, support of not-so-well-working kernels

Thanks!
How to?
Generally idea is simple: make changes and hit apply. If any changes have been made apply/discard buttons appear on bottom.
The first tab, "General" allows to change scheduler, governor/min and max frequencies.
Everything is easy and straightforward, if You need help ask here.
You can always discard changes before applying if you want start from loaded settings.
Profile support:
To save as boot -> press menu key, then select "Save as boot settings".
Boot settings are automatically loaded on every device boot.
RECOVERY
If Your device freezes after boot because of too agressive boot settings (init.d):
Just use vcremoveboot.zip which is placed on /sdcard/. App will ask you to place it, I recommend to do so.
To avoid problems use startup service; its safer and more realiable.
FAQ:
Q: Extreme version?
Yes, I wanted to give some extras for people that support my work.
For now features exclusive to Extreme version are:
+ overvolting capability (max +50mV, 1500mV absolute maximum)
+ increased uv range (max -250mV)
+ CPU usage history page
+ multiple profiles support
Basic functionality will allways remain free. This relies on work of multiple kernel developers, so I really cant ask money for what they have done!
Q: What is it?
Its voltage control app for undervolt and overclocking kernels providing sysfs interface.
More and more developers are releasing wonderful kernels with customisation options. My goal is to make it user-friendly, easily and safe to use them.
Q: What does it mean to undevolt, and what is overclocking?
Read more in "OC / UV 101" section That is a detailed(sort of) explanation what UV/OC means.
Check this great overclocking/undervolting guide by shaolin95 (thanks!) and discussion topic!
Prerequisites:
-root (superuser + su)
-busybox
-OC kernel supporting either UVLF and UVHF
Voltage Control Extreme unlock Key on Android Market!
For now features exclusive to Extreme version are:
+ More than two profiles
+ CPU History page
+ overvolting capability (max +50mV, 1500mV absolute maximum)
+ increased uv range (max -250mV)

-----reserved-----

good one! thanks

How ca I set profiles? I have valid Extreme license.
Edit: Ok, I found it. But is there some tasker to set profiles depending of time or screen state for example?

Go to profiles menu by pressing on the app title, then press + button on the end of the list, enter a name, select it from list, apply
//edit: no there is no such functionality yet.
I can do that, but I'm not sure it shoud be present. I dont want the app to consume any resources when not running.

I think it would be nice feature, but it's just my opinion... Maybe some poll?

I just downloaded SleeperRom on my Epic 4g and this app came in with the rom. I'm curious and want to play around with it, since I am new to rooting. I see that there are few different cpu governors, but I do not know anything about it. So I'm wondering to see if you could list and explain what those are? Any help will be appreciated!

Yay man!
Will this conflict with Trickster Mod?
EDIT: When adjusting sound control gain, it doesn't stick (I don't know if it is because of Trickster Mod)

Uninstalled trickstermod and switched to this. Great app.
Can you implement a "delay" for applying the settings on boot?

Theoretically, appart from the GPU control which will only work on adreno330 devices, the rest should work on any device/any kernel as long as it includes the same version of faux sound (v3 gpl), intelliplug, power_suspend etc...

currently testing it with asus zenfone 2.. it did stopped 2 cores when i select 2 cpu on screen on mode..perhaps this may help that asus bugsh*t of android os in their 5.0r2 rom..will give feedback later..and also many thanks!
edit : it seems that the apps doesnt save any setting that you choose after a reboot and return back to default setting..

Yes, the app does not save it's settings, but is planned for future release (soon, I hope).

Do report back if it helps out with the zf2!

The Setting does not save and could not wake up my phone after hitting the power button.
Reported from Zenfone 5

seems like it doesnt help much, battery drain is not predictable because of android OS drain.. or maybe its because of zenfone 2 processor does not support core management, sometimes i feel like the phone is overheat when using 2 cores only. but the apps really working, it can shuts off the cores..

Sounds weird, on my Zenfone 5 it works ok (wakes up with power button nicelly).... are you sure it didn't wake up? If you're using 1 core it may have a little delay, like 1 second, before wake up).
The saving option is comming soon (next version almost done).
Thanks for your feedback!

If you look on a CPU app, the zf2 does underclock and disable cores automatically to save power, so core management must be supported somehow.

i never seen disabled core on our device..maybe its because of interactive/ondemand governor..but im hoping that asus unlock the bootloader so that custom kernel with hotplug governor can be developed..and i read somewhere ASUS stated that there is no core management for intel processor on zentalk..

Never tested it, but should work with more than 4 cores, the number of cores is read from the system.
