undervolt and underclock ... ?!? - Galaxy S6 Q&A, Help & Troubleshooting

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.

[Q] Question about Kernels

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.

[Q] to overclock? or not to overclock?

Its it worth the time and sage to overclock the galaxy s2 skyrocket?
I have heard it will ruin the phone our that you can't maker it much faster without overheating it.
I'm new to cell modification and i'm interested in learning
The truth of the mater.
Any help is appreciated.
If you are just normal user than stock is good for u.
BUt if u are heavy gamer and play online games and other stuff OC is worth doin it.
OC will make your phone run some what fast but since you are new i don't think you will feel the difference unless you start doing benchmark. Plus stock might get you good battery life.

The other alternative is to undervolt. Some people will use an overclocked kernel, set it to stock values and lower the voltage of the higher CPU speeds for better battery life.

Thanks for the info really helped me decide if i'm going to overclock. Being i'm just a user and not gaming I think its best I don't. I do like the sounds of underclocking as way to save battery life as phoneguy589 had said. appreciate the input guys.
I under clock mine can't tell a difference honestly
Sent from my pocket rocket
I underclock and undervolted mine, battery life has significantly improved, but I'm a heavy user so its still bad
For my purposes I haven't noticed much difference in OC-ing (I don't do a lot of gaming). For me it's not really worth placing the extra burden on the processor (or the potential to fry the processor--not sure how great that potential is but there are always dangers to overclocking).

[Q] battery life issues

im running aokp build 30 and franco kernel on my galaxy nexus and theyre just slaughtering the battery. it comes with a small battery to start, just 1750mah, but this is worse than when i was on stock rooted ics. i had the cpu governor on interactive but i could watch my battery percentages by the minute so i switched over to conservative and it may have slowed down a little. What's causing this? Franco is touted for its battery life, but ive heard a lot of complaints about the latest builds. aokp build 30 has been around for 2 days so... any ideas? preference on kernels?
do one thing goto cwm
Advanced> wipe Battery status
It's better to use cpu tuner and underclock the device when screen is off...try...
I heard that the battery of nexus is not good.so Samsung now providing a battery of 3000 mA check it..
Xperian8~ click thanks if it helps...
OK I'll do that with cwm. aokp comes with the ability to set CPU. any advice on underclocking because I don't know what to do or what to set it to. I didn't know Samsung was doing a 3000mah deal, thought it was 2100?
yes they are..i read that news on gsmarena.com you can search that...
topic>>
Underclocking is setting the max clock frequency to below than the original frequency
Create a profile and you can trigger your cpu settings in screenoff
Create a new profile and underclock..during testing it cause instability so don't check set on boot option..try
Xperian8~ click thanks if it helps...
the only 3000mah battery deal i could find was on accessorygeeks for $25. is that too good to be true?
seems like too good of a deal to be true though.
i understand what underclocking is, i meant to ask what should i set it to? should i change the voltage as well?
and im having a little trouble with your english, can i only create a profile through the cpu tuner app?
I am sorry for my bad English..
You can underclock it max to 600 and min frequency to 122mhz
Yes try cpu tuner and add profile set CPU setting as above mentioned...k?:beer:
Xperian8~ click thanks if it helps...
hmm ok, will the underclock have much effect on performance?
and whats the difference between setcpu and cpu tuner? (i have the setcpu apk already)
try after change it

If it seems to good to be true, it isn't true. Be sceptic of too good battery deals, alot of products are just badly labled and produce alot worse results than what their description states.
You can go as low as your device still works reliably, same goes for the voltage.
I would just search a bit, there are surely others who experimented with clock speed and voltage, i read an article some time ago about battery drain getting actually worse if you clock too low, shame i can't find it atm.

On the basic level over voltage and frequency control? Probably no difference.
If you look at extras, i.e. scale depending on certain events there might be some differences.
The thing about the gnex's battery is that its a measly 1750mah, one of the smallest ive seen in new releases. like the razor maxx has a 3300mah battery...
good thing to keep in mind about that skepticism, but do you think $25 for a 3000mah battery is a fair, not-scam deal? i cant post links yet, but if you get a chance, search accessorygeeks . com for a 3000mah gnex battery and tell me what you think of that deal.
and thanks, ill look into what other people have done for their clocking.
Looks okay, makes the sleak gnexus quite bulky though .

Battery Saving Tips

I have Franco Kernal and Stock Rom + Root Any more tweeks for battery life?
Get better battery stats and see where your wake locks are and work on minimizing them.

i have been a faithful user of franco for over a year, stock clock speed, on demand, noop, and -25mv across the board was good.. but not great.
i have used it on Gnex, N4 and now N5....
i am now giving Faux a test run on my N5... slightly better batt life.. not saying to use either, just saying that in order to get the best, u have to try different things.. both kernels are great IMO
try by making changes for a day or two... get a feel for your phone.. when u make a change thats bad, batt life will be noticeable fast.. u will know
try companion apps like battery guru, battery wakelock indicator, and or greenigy...
just gotta keep an eye on what uses the most mobile data, and what wakes ur device the most... u want the phone to sleep well, which will give u more juice when being used.
rule of thumb, just because it feels faster, but gets hotter is no good... watch changes that make phone hotter... (like a car engine... too much gas or too little gas can increase combustion heat and the engine can detonate)

Great advice.

What is the good Custom ROM and kernel for 5+ SOT?

I used default stock ROM (6.0.1), RR (7.1.1), CM 12.1 (5.1.1) with squid kernel but still my battery don't get even 3 hrs SOT with greenify also. I mostly use it for facebook and whatsapp only. I cant afford a new phone due to this. Plz help me. TIA.

No rom will give you that much of a increase, stock is the best battery in general but there is no way any tweaking will increase that significantly.
Sounds like you need to replace the battery...

That maybe your opinion, but I disagree... Facebook Lite with it's built in Messenger is essentially a specially written browser, uses far less memory than Chrome, removes ads from videos (in general there are less ads throughout) plus you can still get push notifications. I have been using it for months.
If I am "completely wrong" give me some proof. In fact, although the regular Facebook is not the best, it is hardly "mother of all battery sucker apps". It is a space and data hog, but it doesn't use battery any more than REAL hogs like Snapchat, Netflix, Amazon Shopping, SoundCloud, or Outlook, in fact if you do some testing it has less effect on battery than you likely think (granted 2-3 years ago this was different, FB used to be one of the worst offenders).
Regardless, the OP was looking for an app to increase SOT... unless you can lower the battery usage of the display, you are not going to see increases in the magnitude the OP is looking for, from 3 hours to 5 hours, or a 66% increase in SOT. No app change or ROM is going to make a change even close to that.

I agree with @ace Sir Facebook lite is good option .... Now u also have an option of Messanger lite
And also Battery Usage/SOT completely depends on ur usage OP .:angel:

3 hours SOT with greenify is a little off. you need to watch for wakelocks. better battery stats or wakelock detector can be useful to you. and also, if you have greenified the apps that you use the most, it will reopen those apps everytime you open the app, that could do more harm than good. you can try shallow hibernation, or just install naptime and tweak the doze parameters using GeraldRudi's method and quit greenify for some days just to see if this improves.
Then again, your battery could be the culprit, that's always a possibility
about ROM's, every ROM has it's merits, but Motorola really knows how to optimize their ROM, so for now, I think stock ROM gives the best battery life, even if that is marginally better than custom ROMs.
Kernels: Stock moto kernel is very efficient, but you might get a little bit more battery life with squid kernel, it has a great governor that relies on voting mechanism, plus it's just perfectly undervolted to get you some extra battery. probably a 15-20% difference than the stock one.
1) Use AOSP-CAF based ROM like Tesla.
2) Flash squid or Firekernel
3) Reduce the Max Freq to 1152Mhz and Min to 200Mhz
4) Use IntelliPlug Hotplug (Turn off Touch Boost and set Screen off frequency to 400Mhz)
5) Install Force Doze app and add Facebook, WhatsApp and other Battery consuming app to blacklist (Remember you will not get notifications from those app if screen is off).
6) Don't charge too quickly, always charge to 100% and plug when it discharged to below 10% (Recommended to charge at night).
It will improve your overall battery backup and somehow SOT.
At last i am totally agree with @acejavelin Facebook Lite app is made for low memory devices so it consume less memory and also less Battery. Also it's fast and have almost every features.
The real problem here is the device is going on 2, maybe 3 years old... the battery is at it's limit and will need to be changed to get really good SOTs.
My Moto G 2015 used to get 5+ hours SOT easy... not it's barely 3.5... and this is a backup device, it has NOTHING installed in it at all but it was used regularly for 18 months. The battery is just not what it used to be and if I am going to continue to use it as a alternate device I will need to replace the battery. Like it or not, these devices were not designed for more than 2 years of service.

downclocking the cpu is kind of redundant and saves less power than what it takes. the reason why for some users min-max is a battery saving governor. Besides, the performence hit is greater than the battery gained which is not at all more than 2% probably.
you should not fully charge your battery. you can, but the best practice is to charge upto 80%. And anything bellow 25% is not good.
the issue is either wakelock or dying battery, no tweak is going to save him if the underlying issue is not fixed, moreover, doze is the most sophisticated solution to save battery till now, downclocking, hotplugs these are pointless unless one's usage is known to us. I'd suggest to have doze editor if you must have a doze interface.
You can use aosp caf osprey by Ahmed hady...it will give 6 hrs plus sot from moderate to normal use..
