Hi I dont know much about this topic so I have a few questions.
Is overclocking it bad?
Is it possible to have like a switch mode? - Like have a real fast overclocked version and then and real underclocked version to save battery? Would this save battery if you underclocked it?
Thanks for you answers?
overclocking it can cause the device to take damage
overclocking it will eat more batt then a normal speed

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

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).
So I recently downloaded SetCPU for my HTC Vivid and I was playing around with it. I was wondering what you guys think about using it for battery savings? Any specific profiles you guys use that work great? I'm trying to prolong the battery life of my device. Flashing a new ROM has helped a lot, but I want to squeeze as much as I can out of it. Is SetCPU really worth using for battery savings or will the extra processing it does to change around the speed cause it to not help me that much?
Hello guys if you have note 3 (sm-n900) with Kernel -halaszk-UNIVERSAL5420- and want to undervolt your CPU I have found a stable voltage for undervolting, Use SetCpu, first of all set your CPU when you are playing huge games to avoid overheating to min.200 max1300Ghz.
200Mhz-700mv
250-750
300-775
350-825
400-850
450-875
500-925
550-975
600-1025
650-1075
800-750
900-800
1000-825
1100-850
1200-875
1300-950 or 975
If your device overheats after undervolting I recommend to use DVFS disabler.
Do keep in mind, that there are not 2 exactly same devices. There is no stable voltage, which works for all phones with that model number.
Need help
I am using N-900 running Lollipop stock rom 5.0
I wanna do undervolting the cpu for long lasting battery life without flashing new mod rom.
Please give me some advice or recommended kernel for stock rom supporting an undervolt method.
Thank you in advance.
are there tests for battery life gained vs performance lost? would be interesting

1) What is DVFS?
2) Underclock to 200mhz is NOT POSSIBLE!
3) There no undervolting, because my phone stock volt for 300Mhz is 775Mhz, which i use for 300Mhz is 700Mhz and no reboot, nothing. Just bit longer battery life.
4) Setting for 300Mhz-1300Mhz for gaming isn't recommend i. Just enabler Samsung Stock Power Saving. It's limited CPU to 1700Mhz with MCPS (Multi-core Power Saving) with Bettery thermal options and GPU framerates limits to 30FPS for slightly save power and slightly reduce overheating.
Thanks
OK, I have an att galaxy s7 g930a rooted phone. If imy out and about and not by an outlet, my battery is dead by around 6 pm. I'm not really a power user.
Immediately looking at better battery stats which it says since boot, system used 24%, and next is wake lock 6%, then kk launcher at 4%.
For battery optimization, I keep the phone in power saver mode. I also have juice defender ultimate and I run it in balanced mode. I have the setting unselected so the phone does not sync constantly for new emails etc.
I have power toggles and turn off GPS, mobile data, and WiFi when I'm not using it knowing all these transmitters drain the battery. And yet I can't get over 12 hours on a charge.
Try checking the cable n charger see if they are stock charger ..sometimes quick charge doesnt charge the battery properly ...u might need to replace battery if they r good
The battery on an s7 is built in.... not replacable.
It is replaceable u need to a good technician to open up the back using blow dryer type device n then swap the battery its pretty easy
I haven't had the phone a year yet. I really don't believe the battery itself is bad. Almost every situation like this I've seen has been an app draiming the battery... nothing physically wrong with the device.
What screen on time are you getting? What mobile network setting are you using/network are you on? 3G or 4G, if you're on a 3G network make sure it's set to 2G/3G in settings. Try installing gsam battery stats to see if you can identify anything unusual or something that's causing a drain.

I tend to agree with you. I've recently gone through seven S7's... I've exchanged the previous ones and am currently on my eighth device. Among these phones, it was only the international unlocked variant (SM-G930F) and the US unlocked variant (SM-G930U) that showed rather impressive battery life. I was often able to get 1.5 to 2 days of run time on a single charge from each of those models. The 930F was even better battery-wise than the 930U's, which weren't bad at all. Conversely, the batteries in the carrier variants that I've tried have seemed to deplete far too rapidly - similar to the situation you've described with your phone. My current S7 is an SM-G930P (Sprint variant) and its battery seems to last half as long (or less) than the unlocked S7 variants I've used.
The most generally disturbing thing for me about the GS7 is that there has been one or more significantly undesirable issues that seem exclusive to and inherently present among each of the model variant categories. At least this has appeared the case based upon the S7's that I've personally tested. For me, it seems there is no variant model of this device that's without seriously objectionable issues. However, finding some way to make the carrier-variant batteries last significantly longer would go a long way toward making other said issues more tolerable.
You could try greenify if you got xposed installed. There is another module too, but the name escapes me right now.

From what i've read the root method using eng boot for snapdragon phones makes the cpu run at the highest frequency, so yes the battery life will suffer.

Hmm, so the rooting method for the SD820 equipped S7's effectively overclocks the CPU? Perhaps it changes the multiplier?
The 4 cores on my unrooted SD820 equipped S7's have always idled at 307 MHz, and then spiked up as needed. Do the rooted SD820 equipped S7's idle at a higher clock speed? Or do they simply have a higher maximum clock speed - i.e., beyond 2.15 GHz? Either way, I can see how that would suck the battery down noticeably quicker.

It has to do with the governor, its apparently set to performance rather than interactive. Check what yours is set to, cpuid app can show you that.

Ah, that would be the CPU auto-scaling mechanism, if I'm not mistaken. I think mine's obviously set to interactive since the cores idle at 307 MHz. I'm guessing that if scaling were set to performance mode the cores would be running at full speed instead. And yes, that would drain the battery far quicker! And I sure DON'T need this 930P to drain its battery more rapidly than it already does. I'm currently playing with the debloater app to see if I can make some improvements tha way.
