Will I get better battery life after using CFautroot?
And what is the success rate for first time users? (chances of screwing up my phone)...
thanks!

Only the things you do after rooting can have a good/bad effect on battery life.
Rooting will do absolutely nothing except maybe a placebo.
Success rate only depends on circumstances such as accidentally removing usb cable during operation.
Otherwise if your phone model is supported then it should work 100% of the time.
Lgrootnoob is right, the success rate only depends if there is a problem with your device such as not connecting to the computer right pulling the cable, your antivirus might jump at the programs you get from here, as for your battery, it depends on what you do, if you want to overclock your phone (make it faster) it will decrease battery life depending how much you use increase it. i would get the App Performance controller when you root your device but only if your willing to do a little research into governors and i/o schedulers you can find which ones you want and get tons better battery performance.

Hi, my Triumph should be arriving in the mail in just a few days and i was wondering which is the best kernel or ROM and Kernel combination that is best for battery life? I've heard that battery life on the Triumph is not so good. Maybe it's false but i would still like to know.

I would go with CM7
That's what i was planning on. Does your Triumph give you battery problems?

The battery life is a lot better now with the latest builds of CM7 and MIUI.
I just use CM7 and leave wifi and bluetooth off, no juice defender or anything like that and I can easily go all day with no charge, typically about a day and a half and my battery is getting low but it really depends on what you are doing like games, wifi, videos and whatnot.
Before I think there was a problem with the battery draining while in idle but things have cleared up since then, There are also third party kernels you can OC and everything, but you can use them to undervolt as well to save some battery if you know what you are doing. over on androidforums there is a lot more chatter about this phone, just so you know.

Thanks. I got my phone today and im loving it so far. Do you know which of those third party kernels are good for battery life and that i can install over stock? I'm not quite ready to install a ROM yet but i already did the HTC Thunderbolt Build.prop tweak and obviously im rooted.
It's usually not the kernel but whatever governor you have it set to use. Even the stock can get improved performance if you switch the governor to such--”performance”--but I'm probably not the guy to tell you about which one is best.
I also have the silly feeling a lot of misconceptions abound here...in the form of ”I changed this setting and now my device lasts longer..., oh btw I no longer play with it 24/7.” In other words, use drastically impacts battery performance. JuiceDefender is an amazing tool but it won't do you a bit of good if you're testing out your phone's Adobe Flash capabilities regularly.

The Savagezen and interactive (not sure if interactive is on any of the kernels for this phone.) gov isn't that great. At least not in my experience. I had SmartassV2 on my girlfriends phone and it got ~3600 on Antutu benchmark at 1.5 and when I used Savage at 1.5 she got ~1700. The interactive gov made my friends Dinc2 noticably slower. Just switching home screens it lagged to the point it was hard to get into the app to change the gov.
CM7 + TheOC kernel allows adjusting voltage & overclock or underclock. You really should flash a CM7 ROM. Having it just rooted can be dangerous because you're not using a custom recovery to make a backup image, and if something messes up, you don't have a backup ROM to restore. Going to a different ROM forces you to make a backup, then there's a backup to restore if you mess things up.
Governors just tell the CPU how fast to ramp up to a certain frequency, & how long to stay there. It's hard to balance fast ramp up (less lag), and low battery drain (spend more time in the lower frequencies). I like interactive/x, find that smartassv2 spends too much time in the mid frequencies (~500) even for light work. Using the app CPU Spy helps a lot to see what's going on. Also it tells you whether your phone is sleeping properly when screen is off, which is a big factor for battery drain.
Ok I'm kinda new to the whole overclocking thing and I was wondering what are the best settings to use if I wanted to(for instance) save more of my battery. I've done quite a bit of searching but I wanted to make sure that the voltage settings aren't different on different ROMS or phones. I'm on Zeus V3 for the record. Any help would be greatly appreciated! Thanks for your time.
Stable settings definitely vary from phone to phone unfortunately, even if they are the same device. So basically its trial and error, no matter what anybody suggests. Generally, the more you can undervolt and stay stable, the better battery life you will have. You're just going to have to experiment a bit, and just make sure you don't save any settings as boot settings until you know they are stable. I know there is a guide to overclocking somewhere on the forums, I just hate searching on my phone.
Quick tips, start with only moderate undervolting, and crank them down gradually until your phone is at the limit of stable to maximize battery life. Use the 'stability test' app in the market to test for stability. Also, running other benchmarks, such as neocore or quadrant, without freezing is a good test.
Hope I helped!
PS, I've come to the realization that it all doesn't make THAT huge of a difference, and if you switch roms anywhere as frequently as me, its a waste of time. Not to discourage you, just my two cents. If you like to pick a rom and stick with it, then definitely play with it.
*edit* Got on my computer and found the guide for you:

Obviously, since the guide is based on a captivate, the values you will end up with will be different, but he explains the process of fine tuning very well. Enjoy!

what i do with all my ROMs is put it from 100 mhz (min) - 1600 mhz (max)
and put the governor to "ondemand"
i usually get about 18 hours on battery life a day.
give it a shot doesnt hurt to test it out cause you could always charge your battery haha
Hello guys
I'm not a new user in kernels or ROMs .
I have a low-decent battery life ,and I'm sure there's a way to get a better battery life with undervolting .
I want to know
what is "undervolting" ?
What is the biggest damage it can cause?
What is PVS?
How do I know ,how much I can UV?
What are the steps to undervolt?
What I gain from UV (despite battery life)?
For your info ,I'm using AOSPAL ROM +FAUX's latest 16u kernel .
Thanks

Hi,
Most of your questions have a reply:
About undervolting: http://forum.xda-developers.com/google-nexus-5/general/nexus-5-undervolting-thread-t2537000.
CPU binning: http://forum.xda-developers.com/google-nexus-5/general/cpu-binning-nexus-5-t2515593.
The "risks" are instability like hard reboot, SOD, etc.... To find a "safe" value you will need to test by yourself to find what undervolting your CPU can handle, not all CPU's are equals.
Undervolt by steps like - 25mV, don't set your new values at boot unless your are sure it's stable (or you could encounter bootloop), test for a few days under different conditions (as your use).
The gain apart battery life (but you will not gain that much as people tend to think) is a little less heat, but again nothing huge..., better is to test by yourself and see what you will gain... or not.
Battery life depends mainly of your use, apps, signal quality and settings like, screen brightness, synchro, CPU governor, etc... In my opinion check first what could be the cause of your low battery life (and what is low battery life for you???) before play with undervolting.
As said above, undervolting will get you very minor battery life increases.
More than likely you have an issue, or its just your setup and usage giving you the battery life you are seeing.
Undervolting will not change any of this.... You'll gain only minutes of battery time.
Try some troubleshooting in the below thread to see if you have an issue, or how to setup for better battery life. Read through it a bit, from the last page and work back a bit. You can post meaningful screenshots there too. From gsam or BBS.... not the stock battery screen, it has no real useful info for finding issues. Good luck!!

Nexus 5 Battery Results
I've been undervolting many systems for many years, primarily Linux desktops and some servers, and the primary benefit is that you get less heat output which means when running cpu-intensive tasks the temperature climbs slower so the throttling of the clockspeed kicks in later, so your phone will be faster in certain situations. If you take a phone which has been idle for a while and run a benchmark, and then immediately run that benchmark again, the 2nd time gets a lower result as the phone is still hot from the 1st. This makes drawing conclusions about settings really dificult but it illustrate that throttling from heat is affecting speed.
For most users their perception will be the phone runs cooler.
You do undervolt at each step in the processor's frequency, and each step is a trial+error activity, the throttling I mention means finding a stable under-volt at the higher frequency which is labour-intensive,i.e take the max clock, and undervolt it a little, run a benchmark which forces it to run at high clockspeed, and if it passes that test then run it again at the next step down in frequency. Once you've got the most stable top clockspeed, then do it progressively for all the other voltages on the way down.
In some platforms in Linux and Windoze, we wrote scripts which save the stable voltages and then undervolts a little and runs a stress-testing benchmark and if the system hung it wouldn't save the current voltages so the previous higher voltages were safer, stick that script in a startup script area and leave the compute to do many self resets, and you've calculated your device's voltage range. I wonder if someone has that done for Android??? For a laptop the FAN would run slower saving battery time and for laptops that would lead to say 20% better battery life but on a phone it won't make much saving as no fan.
Your phone will run most of its time (like 95%) at its lowest frequency, so for effort/benefit just focusing on dropping its voltage will gain the most in the phone running cooler.
Battery life improvement is marginal, if you look at your battery stats its down to your application settings and screen brightness, i.e. how you use and what you do with your phone. So if your battery life is bad, use your phone less!
I carry a slim USB battery, it is the $/effort/benefit the best thing you can do, $20 doubles your battery life, if you get one with a 1.5A-2A output in just a few minutes when the phone doesn't mind a battery attached, will dwarth every possible tweak and hack anyone can form in benefit.
since i use my galaxy s6 for basic stuff , browser viber whatsapp , ebay , amazon , no games at all , can someone help me to undervolt and underclock my phone sisnce i dont need all his power , i like to to it to gain extra batterylife ,
i use arter kernel 8.2 and v11_exposed rom ....
i miss my old experia z3 with 8SOT and 2 days battery life
I get pretty good battery life on mine. Undervolt and underclock is the same thing. I don't understand why u would want to do this to a great phone. Buy a Nokia 3210 you should get loads of battery life and fast enough for you
My stand by time is easily 2 days just using basic things. I do like to use my phone so I do get 1 day which is good enough for me.
Check the wakelocks that should help way more the undervolting

Not the same thing at all! Undervolting is more sensitive and gives better results although very risky!

Ya I understand! I don't see the point in undervolting unless you have heat issues which would make it more stable. I know u can extend your battery life a small bit but its not like u well get days out of your battery by undervolting and underclocking.
The best thing is kill the apps that keeping your phone awake. That would save more battery but at the end of the day you will still be plugging your phone in to charger.
What they need to do is improve battery's
Agree, let your cpu/gpu handle its tasks. For others, maybe they preferred on doing this undervolting stuff etc.
Others wanted to freeze wakelocks, alarms, services just to lower battery usage.
I find it funny LoL *kidding I would not bother buying S6 at the first place if thats how you usually use a phone. But it is your choice
You could opt for units with larger battery capacity but with good SOTs and reviews.
Is there a way to have more performance, more free ram and better battery without root? Actually I achieve 4.5hrs of sot. Thanks!

Buy a different phone?
Android intentionally keeps apps in memory for faster opening so less free ram isn't exactly a bad thing.
Exactly. I tried disabling/uninstalling stuff (and pretty much!) from my Android phones so many times and NEVER saw any performance improvement. It is all imho placebo effect. Every custom ROM MUST be slower than stock, if for nothing else, because it is deodexed. The thing is that people flash new ROM on empty phone and go woooow, how fast... yea, wait a couple of months S8+ is fast enough, and keeping more free RAM will only decrease performance, because as mjones73 stated, it keeps apps in RAM in order to run them faster. Better battery? Probably by disabling or not installing some stuff that runs in the background, but better yet - get a power bank or just... charge! The wall outlets are everywhere. I don't get this tuff with more battery. Just plug it in and charge. New batteries can be charged as soon as they fall below ~ 80%.... and it won't affect battery life etc.
