Undervolting. - Samsung Galaxy Note 10+ Questions & Answers

Hi All,
I was just wondering if anyone has tried undervolting in order to make the battery go that little bit further.
Thanks,
Speedy!

I no longer tinker with these things, but in the roms and kernels section there might be a custom kernel for that

Help with FPS and scrolling laginess, TIPS?

Hello all. I wanted to see if tips could be posted on how to increase scrolling laginess and increase fps in things like video and games. I bought my wife the shift and Ive noticed its alot better at mobile gaiming and video playback/recording.
Ive rooted and installed myns warm two point two along with netarchy-toastmod 4.3.4 cfs havs more nosbc.
Ive overclocked to 1.2ghz using setcpu and left the governor on smartass. (no profiles)
These seem to have made a visual improvement, but I want/need more.
So my questionis are...
Is there specific kernels that will help get the results Im looking for? (Im more insterested in performace, but would like batterly life is possible)
Are there any hidden tips that can be done via command line etc that will change things to allow for a better fps performance?
ANy help, links, etc will be appreciated. Ive been searching for weeks already just to get myself rooted/romed/kerneled.
The Shift has a better processor and a better GPU. I don't think you're going to be able to match it by overclocking. There are ROMs that tend to be a little smoother than others (MikFroyo 4.6 is nice), but there's only so much that can be done with the hardware. The Evo itself is almost a year old, and the QSD8650 SoC it uses has been available since Q4 2008.

As bkrodgers said, the Shift has better hardware than the Evo. My roomate has one, and that thing really is smooth, even on the stock rom. It nailed like 1400 or something like that on quadrant, not even overclocked on a stock rom. The only changes I ever make to my phone that affects the scrolling is the kernel. My phone doesn't like havs, the voltage scaling makes it unstable, and it lags severely, on any havs kernel. I get the smoothest experience out of my device from a kernel that has no havs and isn't undervolted. Of course, you get bettery battery life out of a kernel with havs, if your phone can tolerate it. Every phone acts differently on different kernels, which is why there are so many to choose from. So you can find the one that's 'just right' on your device. It takes a little playing around and kernel swapping to find the right combo. And as far as I know, basically all the kernels that have been available for a good number of months now, have the fps fix already baked in. When the Evo's first came out, FPS was capped at 30fps. Since then, all the custom kernels allow for it to go much higher than that, sometimes up to 60fps. I don't believe there's much more you can do with that.
Also, for what it's worth, you might want to try out an AOSP rom. They have much less crap in them, and they tend to run very very smooth (in my experiences). Not to talk down on any sense rom, as I also love sense, and 99% of the time and more than happy on whatever sense rom I happen to be running at the time. Fortunately, the Evo has quite a few selections on roms and kernels, so there is quite a bit of playing around and tweaking you can do, in search of the perfect setup.
thanks I'll probably try miks rom to see how that goes.
I understand about the hardware and that the shift has a better cpu, but is there anything else other than what I have already done to make everything nice and speedy UI wise? I think the biggest culprit is the app drawer being clunky. (like this on the shift as well) No settings in linux that can help there?
Oh and kernels. Ive tried 2 of netarchy-toastmods kernels and havent really noticed a difference. Both have had havs. Should I stay away from these type of kernels to get better visual performance?
ANy other tips on which kernels youve tried and noticed better ui results?
ah yes the elections are great. lol I guess I'll have to try a non havs kernel to see how they perform along with the senseless roms.
Thanks all

You're welcome. Just bear in mind, that if you do try out an AOSP rom, that they have different kernels to use. You must use a kernel that was made for AOSP on an AOSP rom. So don't go trying a netarchy kernel on an AOSP rom
Also, I didn't have as good a luck with net's 4.3.4 kernel's as I did on the 4.2.2 or 4.3.2. Also the 4.1.9 kernel's worked great for me. For some reason, the newest one's don't give me the best performance.
As far as tweaking things using ADB, I don't think there's anything you can do FPS related. I believe there are ways to adjust the undervolting in a kernel, using adb, and things like that. But as far as I know, the FPS is what it is at this point, although it will vary from kernel to kernel.

Next step - learn how to OC/UC?

Hi,
I'm basic user, i do know how to Flash Rom's/kernels and all that basic stuff, but i want to learn about these things:
# Radio
# Guvunor?
# OC and UC
# Baseband
I remeber i saw a thread telling all these things, but i can't find it anymore. I would be thankfull if you could tell me these things, or link me to a guide or something like that.
I have a question, sometimes i see ROM's that's overclocked, do i reduce the phones life when i Overclock?
Thanks guys.
baseband is the radio. Dont flash a radio if you are a beginner
Governor controls the CPUs ramp up/down times and how the speed behaves
Overclock increases the max speed
undervolt lower the voltage used at different speed stages to get better battery life
Your best bet is to install any 4.0.3 or 4.0.4 custom ROM to try out, then flash a custom kernel. For a beginner you might want to try either Faux's tuna kernel or the minimalistic kernel. They have the least "hardcore" experimental stuff and tweaking
If you want to get into the extensive tweaking and tuning, the Glados kernel is easily the best.

Why not flash a radio if you're a beginner? It's the same method as flashing a ROM / Kernel unless you plan on fastbooting the radio.
Beginner kernel? not really... all the kernels for the most part work out of the box without any extra tweaking. I recommend Franco kernel.
If you're not going to encourage someone on flashing something then they will never learn how to do it. The best way to do it is to experience it, and it's honestly not that hard to do.

But flashing a radio and something going wrong can actually hard brick the phone. Same with any type of firmware you flash. So telling someone who is asking all these sorts of questions to do something with dire consequences is not something I can do in good conscience

Yep. Bad flash with a radio is a good way to **** your pants if you're a noob. Best to get a few soft bricks or I dunno wat happen under your belt before flashing a radio. For real.

So in your saying, this is saying that if a person accepts a OTA coming from Google they should be paranoid whether or not they should apply the OTA update?
Because upon flashing the OTA update this will update their
1. ROM
2. Radio
3. Bootloader
Is that what you're implying? didn't think so. If one lives in a world filled with fears and paranoia, then they will never fully be comfortable with what they're doing.
1. Flashing radios, like said before, can seriously mess up your phone if something goes wrong; but also as already said, it's as easy as flashing a zip in recovery. Some newer ROMs even bundle with the newest radios.
2. Governors are in laymen terms different personality's for your CPU. In performance it caps the frequency whenever it can, as fast as it can (obviously for performance). In Conservative it will gradually increase and decrease in an attempt for greater battery life. There's a few others but as long as you're not in performance mode I haven't really seem a huge difference between them. Though if you're running a custom kernel they usually have a guide for what governors are used for what (since they usually customize them).
3. Unless you're creating your own kernel, you really won't gain much but Overclocking or Undervolting past whatever kernel you're using (save stock of course). I'd recommend sticking with a kernel (such as franco or leankernel) and just choosing a max/min frequency & gov that fits you. In the same vein, in response to your specific overclocking question, keep mind just because the kernel is overclocked doesn't mean you have to choose the highest frequency they give you. I'm running CM9 and leankernel and the kernel has a max freq of 1350, though using SetCPU I set the max frequency to 950 instead (also keep in mind that most ROMs have CPU settings built in, so SetCPU is mostly optional but it does have a nice widget)

Pimp My Rom + Custom Kernels

Has anyone had good experience with using Pimp My Rom and a custom kernel such as KKO? I've always heard people talk about Pimp My Rom in the comments on so many ROMs and Kernels that I tried it for myself and not sure how the performance will be. I'm more of a battery first kind of person who can bare a little bit of lag. Anyone have some good advice or had really excellent results and care to share their setup? I know kernels and governors vary on device and the user but just would like to see. I apologize if this is already posted but it seems to be a dead topic and dont want to revive a very very old one.

kernels question

hi to all of you i am new here i root my gs3 and running cm10 stable version but i see a lot ppl talking about kernels so what is the differences between them and what the do to the phon

Some kernels allow you to overclock the CPU and change the voltage settings. Sometimes it helps with battery and performance. Depending on kerenl can sometimes make the phone feel a bit snappier and smother. The kernel i usually use, and a lot of people is from ktoonsez. You can read about it here and get an idea

My phone can't handle non stock kernels?

Hello fellow XDA brethren! ​
I am reaching out to whomever may be able to give me an "advanced" type of explanation in regards to
modified kernels being applied to my phone.
T-Mobile Galaxy SIII (32Gb White)
I seem to be having issues with many of the kernels offered by some of the excellent developers in the t999 forum.
Namely, ktoonsez, and the other famous dev who's name escapes me right now.
When I flash kernels like those above, my main symptoms are:
Artifacting / Glitchyness in GUI.
Now... I know that some kernels are geared towards battery life and are undervolted to a point, I've tried everything,
volting back up. I've been flashing every one of them properly as well. I know that people say "all phones aren't created
equal", but i refuse to believe that mine is so whack that I cant even use anything other than stock kernels.
I firmly believe that these symptoms are from GPU overclocks that my phone simply cannot handle, (explains artifacts?).
I can use different roms with their respective kernels such as CM10, and a few of the other popular TW roms that are offered.
Here's what I was wondering:
Is there any application that I can use to control GPU overclock (to see if tweaking with this fixes it, to narrow it down
that my phones GPU is just very sensitive)
Are there any kernels out there for touchwiz that give me some nice benefits that dont have any GPU overclock?
What other methods can I fool around with to see exactly what part of my phone is weak?
Any suggestions are appreciated!
I get LOUSY batterylife / performance on tmo stock kernel.
If it were a PC, the first thing I would suspect of causing the artifacting issue is bad video memory. Combine that with the poor performance on stock, it stands to reason that you may have gotten a bad phone from the factory. I would suggest that you consider simply having it replaced under warranty, if you do have bad RAM in the phone the problems will only get worse.
