[Q] Kernels and roms for best battery life?

What does everyone find is the best kernel for battery life?
Sent from my SGH-T989 using Tapatalk

personally, i don't think you need to be concerned much about battery life
i'm surprised myself, as i'm a heavy user, and this phone can last very long time on a single charger, pretty much a full day without the need to top up the battery
and that is OC to 1.8 Ghz
my old Nexus S wont last 4 hours with the same usage i give to the T989

it really depends on usage there isn't one golden battery saving combo in my opinion

I would like to know as well because that would be my main reason to want to root the phone.
I'm mainly just looking to get rid of bloatware and better battery life, which rom do you think would be best XDA?

believe it or not, the stock ROM in this version of the phone is very decent for battery life
you can find tune it with SetCPU if battery life is your goal, and NoBars, and optionally JuiceDefender

What about all of the uv kernels? I need to squeeze juice as i'm a power user.

Im getting awesome battry life and even better performance on BeastMod v2.0 with Synergy 0.03 Kernel. With SETCpu i have it at 1.6ghz MAX and 384 Min with LAGFREE scaling. Buttery smooth!

Seconded. And I didn't even OC.
I am also running:
1) Juice Defender Ultimate
2) SetCPU for screen off profile
3) NoBars Battery Saver
This combined with any bloatfree ROM will net you awesome battery life on this phone.

what setting are you using for screen off profile in setcpu?

I use to use 192 min 384 max, but had some SOD problems with the new BeastMOD 2.0 rom, so I used 384 min 432 max.

What about this new phantom ROM?

BUMP......

Juggernaut 2.0 with Jugs 0.3 Kernel
So far for system stability this is an awesome combo. Im still going to wait a few days to talk about battery life.. i spent the last 2hours texting my girlfriend and it drained 50% of my battery.. so yeah hoping the next fews days things will pan out.

2 users reported great battery life with it...

I'm also using BeastMod 2.0 with the latest Synergy Kernel 0.05. I use SetCPU to do min 384 max 1.5ghz (not overclocking) with lagfree governor. It is incredibly fast and my battery life has been solid. I only have one profile on SetCPU which is 384 min 384 max when screen off. All is well here.

What do you consider. Im using 0.05 and this phone is chewing up battery..i estimate 6 hours tops for mine with this kernel...itsjust so fast tho that i cant say no.

SetCPU, What are your settings?

Anyone try SetCPU after rooting? I can adjust the min down to 192mhz. Anyone have any idea how safe it is yet as far as sleep of death?
Sorry if this is not in the correct forum

You can test whatever you'd like. I tried it too so just don't check the option for set at boot.
-Hercules composed this post and threw it at your face to be read-

Just worried since it is my alarm clock too, a sleep of death could lead to a sleep of no job

Some believe tegrak is better for samsungs
Sent from my SGH-T989

i believe there was something about needing a custom kernel that supports a cpu oc app. something about it not engaging both cores... just one of them. somebody out there knows more than me about this i'm sure.

I think i remember dsexton702 talkin about needing a kernel for tegrak to function properly

A custom Kernel is only needed Fri overclocking.

Had mine set on 192 min all night and no issues with waking up so far.

Tegrak probably won't work properly if I'm correct set cpu or oc/uv beater should be fine. Tegrak was used for samsung processors. Qualcomm processors are able to scale better at lower or higher frequencies.

It will never engage both cores that is asynchronous. Both processors work independently from each other. This is why you see lag. Both processors are never at their full potential. Qualcomm design the processors for best battery life in mind with good performance. There is a way to get both cores to be synchronized though if it matters to you. But expect worst battery life.

Almost forgot we have a snapdragon lol

The one we have should also overclock very nicely. The APQ8060 is the same one in the Touchpad and that one easily does 1.9Ghz.

When I installed setcpu and had it auto dectect speeds It atuomatically set the min at the max and the min at the highest clock speed. Is that normal? Did anyone else notice that?

That's normal. I have noticed the same thing on the g2x and g2. I wouldn't worry about it unless it won't let you change it.

Is it currently safe to overclock the phone using this app?

Yes. But you would need a kernel that supports Overclocking and Undervolting.

[Q] Overclocking!?

Hey guys,
I actually rooted my One v and also began using a custom Rom - KangBang v3 with hellboy kernel. I found the overclocking and voltag-controll in the menu. What is the maximum you wold overclock and at wich voltage?
Sent from my HTC One V using xda app-developers app

I personally don't use and prefer OCing above 1.5ghz.at 1.9ghz,phone reboots every time an app is opened,freezes sometimes...
Sent from my One V using xda app-developers app

i never overcloked my Phone for me he is fast i think there is also a risk when you overclock

1.5 is pretty stable, any higher than that is a gamble. I got pretty good scores in antutu at 1.5, but not high enough to warrant constant over clock. Heck I usually run with 768 MHz on the high side for tiny bit better battery life and don't notice any slowdowns.
Sent from my One V using xda app-developers app

I go 245 low and 1200 high and 1708 low and max for games, that's the max without reboot
Sent from my HTC One V using a laser

Ok, i overclocked it up to 1.5 GHz maximum. At this frequenzy gta III runs smooth xD.
But for daily use, this drains the battery too fast -.-
But I think 1ghz is enough for normal use without gaming

Hey guys,
I am using Surprimo Rom v30
just wanted to ask if it has any such option of setting the processor setting
I haven't found any such settings during my usage.
So if it doesn't have such settings then what is the default setting set to?

I overclocked to 1,5 Ghz and use it daily with SmartassV2 governor. Battery lasts enough to load it back up overnight.

Your insane for trying 1.9 xD.
Don't exceed 1.4.
Overclocking a 1ghz kernel to 1.9 is dangerous.
Sent from my HTC One V using Tapatalk 2

even at 2ghz,there is no damage done to ur phone.generally people feel that it will damage and fry their phone,but thats not true.it only may reboot and freeze just for some time.there is no serious damage as many feel.

Running at 1.2GHz max right now. I'm too paranoid to go any higher than that. It got rid of the minor lag issues I was having (occasionally seeing "loading" when going back to the Sense home screen from an app)

CM 10 Clock Speed

So I have recently installed CM 10 on my S3 and I'm loving it. However i am a bit worried. The S3 is said to run at 1400 Mhz or 1.4 Ghz. But when I go into settings then performance, the max is set to 1512 Mhz and I didn't touch anything! CM sets it to this by default. My question is does Cyanogenmod overclock your device? Or is that the clock speed that S3 really runs on? My phone has also been getting hot lately but I'm not sure if that has to do with anything at all. Any help is Greatly appreciated!!!

If the kernel supports it. But stock touchwiz runs at 1.5.

1400 mhz is the max stock clock frequency on the international version (i9300) and 1512 mhz is the stock max freq for the at&t version (i747).
I haven't had any issues with heat. Try running an app to check the CPU temp.

Also how is or battery life? I know when my phone gets hot its because something is eating my battery. I by some controls on said apps and I am running at 1.9 with ko heat issues

The battery life is great I'm not sure why its getting hot

I would use better battery stats just to see what is accessing or CPU. Also u may wipe and do a fresh full clean install. Like I said I have mine over clocked to 1.9 with no undervolting with no issue. But also keep in mind every phone is different.

[Q] Undervolting my HTC One X makes it slow as hell!

Hello!
I am playing arround with XM Kernel #235 and Black Pearl 5.0.1 ROM.
With stock values @ 1200MHZ AnTuTu scores arround 16000 but when i UV it - my phone gets uber slow (only on benchmark, not UI) and scores only 2500.
Even Subway Surfer seems to be strugling abit.
Another thing, I tried OverClocking to the limits.
This is what happened:
http://forum.xda-developers.com/showpost.php?p=39069291&postcount=3693
Hello
I have some questions regarding #235.
I am using it on Black Pearl v5.0.1
I tried to overclock as much as possible
3D at 766mhz
2D at 620mhz
EMC at 900mhz
CPU at 1500mhz
yet I don't see any difference on any benchmark except my phone is hot as hell =)
Is it possible those values don't stack?
I am not getting any reboot or lag or anything. Stable as rock.
Thank you for your answers

What is your CPU variant and how much did you UV?
Sent from my One X using xda premium

I have variant 2 using 1500MHz @ 1100mV.

Hm, what was the original value? I can't check right now...
Sent from my One X using xda premium

1237mV stock.

Try a milder UV.
Even -100mV is considered heavy UV so you should stick with values not much higher than that.
