What's you're battery saver?
I use both.
But I know I can only use kne.
Help me decide.

I use Battery Booster and Locale (for brightnes, display timeout etc), but I guess u can do all of it in Tasker!
I fully charged the phone to 100% and turned it on at 7:45 then I went back to sleep. I woke up at 10 to see the phone at 95%! Now, I'm currently using the Anker battery & I'm running on ARHD 3.6.13 with faux123 v0.2.8 kernel. The brightness is at its lowest & auto-sync is off. What should I do?
I recommend using Battery monitor widget Pro to see how much mA is phone using during sleep and when screen's on. Then install Better Battery Stats ( http://forum.xda-developers.com/showthread.php?t=1179809 ) and figure out, what is eating your energy
also, try undervolting

What's undervolting?
Undervolt makes your cpu use less energy. for undervolting try using system tuner pro or faux clock (here's link for faux's RootzWiki: http://rootzwiki.com/topic/4550-app09-beta-snapdragon-dual-core-oc-control/ ) But be aware that not every CPU handles heavy undervolting well. Do nandroid backup, then Start with -25mV.

Try changing cpu governor to intellidemand (faux's kernel default) and min speed for cpu to 192. It may slightly improve battery life.

Hi,
When I was on 3.6.x,it was suggested that I try a Bricked kernel,which you can find HERE
I am not sure which one,but they tended to be more battery friendly than faux.
Read the thread.
You might get some valuable information.
I'm using the Faux Kernel on my Skyrocket. I'm using Set CPU for speed control, under-clocking for more battery life.
I head the terms UC, OC, UV and OC. When I use Set CPU, I assume that when I set maximum CPU speeds, I'm under-clocking. But what is under-volting? Is that different? Is there an advantage to doing both?

There is an advantage to undervolting you need either fauxs app or systemmtuner to do so.
Undervolting is giving the cpu less power and asking it to do the same amount of work it was doing before

That sounds a bit more dangerous in terms of doing damage to the phone or having reboots etc. when you are giving the circuity less power than it was designed.
For those who chose to undervolt for power savings, it is usually done in conjunction with under-clocking, or is it a one or the other type thing?
Not really, under volting is not as dangerous as over volting (used to also achieve higher overclocks). Over volting can actually damage hardware if you provide too much juice.
Under volting just reduces the voltage, if its not enough the app freezes or worse the phone reboots. If that happens, bump it up one more step (+12500) and you should be fine. Find where you can go low but still be stable (for me it happens to be -87500) you will save more battery.

all good correct info. I highly recommend fauxclock, its very user friendly. I have my phone undervolted -100mV and underclocked to 1.2 and I'm getting 13 hours heavy usage with around 5 hours on screen time, with NO juice defender. For this phone, that's pretty good

My exact setup. -100mV UV, and 1.188 gHz UC. Went from 100% to 0% in 1 day 7.5 hours with 3 hours of screen on time. No juice defender either. I think its pretty food. Using faux 009u, btw.

Only issue I got with Fauxclock is that it saves the CPU clocks I set (say 1.298ghz max) but it doesnt actually save the voltage after a reboot. I look at the VDD table and its still stock.
So only way to get it to work is to manually edit the VDD table itself. Not sure if this is by default that fauxclock doesnt actually save the voltages after a reboot.

Don't see fauxclock in the application store, sorry, Google Play Station.
Thats cause its not in the Google Play. Its a separate app at this location

Got it, thanks. And the under-volting is so easy with Fauxclock, I've set it down 100.
So I've got SetCPU doing the CPU speed, and Faux for the voltage. Seems a bit redundant, since Faux also does CPU speeds, but SetCPU has some cool configuration settings where you can actually have multiple settings for CPU speed based on various conditions such as battery life remaining, processor temperature, time of day, phases of the moon . So I guess I have to keep them both. Hope they don't interfere with each other.
Fauxclock has very basic CPU clock settings, it was created just for that faux compatible kernels so the original developer didnt spend weeks on it. It was just a simple and fast and effective GUI to set min/max clocks and also voltages (global scale). You can however set one other clock which is the "screen off" clock, but thats about it.

they will, use one or the other. U can manually change global vdd table and use setcpu, or forego advanced profiles in setcpu, but u can't/shouldn't use both
FauxClock force closes on launch for me..
EDIT: Getting a Faux kernal fixed that. Wow I feel dumb.

Are u using faux kernel?
Any tips or thread about how to manually change global vdd table so that I can use SetCPU for the profiles and adjust voltage manually?
Is there a risk to that? If I set it and the phone won't boot, it sticks!
use Gideon UV/OC script and change vdd as u see fit. If it doesn't work u can always flash Gideon stock back

What exactly is the difference between flashing Gideon's script or just using FauxClock? Thanks!
fauxclock gives u dynamic min/Max and voltage control as per user settings. Gideon is pre-set and makes use of init.d script. u can change it, but every change requires a reboot
I have juice defender ultimate which it stops mobile date when screen is.off since it does that do I still need to set my screen off CPU frequency low still or it doesn't matter since juice defender stops mobile date?
Sent from my HTC
Mobile data and CPU frequency are two different things. If you want to save battery, also lower the CPU frequency, but beware not to put it below about 400mhz.
Hi all
wanted to know how many of you use juice defender and is it good for battery life or no ?

think of it logically....what it does should help on any samsung stock ROM....incase of custom roms/kernels, you have ondemand, conservative governors which would manage your battery....plus the devs must be adding battery saving features into the roms too.....so it may be unnecessary in that case
but i use juice defender nevertheless....just hoping it improves my CM10 battery life some bit
