Undervolting the GT-N7000 for better Battery life

Hey there ,
so i wanted to share share my awsome Undervolting results with you
At first im running on Chasmodo's latest CM 10.1 i really appreciate his work ! I use the latest CM 10.1 Kernel.
With his rom and this voltages u find under this introduciton text i could get nearly a month with Standby time
(without doing anything , Wlan turned on , Data off) i attached a screenshot (29 Days and 5 Hours sorry for the German language)
Every day i plug my N7000 out from the Loading station its 5am on 3pm i lost 1%.
to change the Voltages i use SetCPU (full version)
1400 MHz
1200 mV (Stock: 1350mV)
1200 MHz
1100 mV (Stock: 1275mV)
1000 MHz
1000 mV (Stock: 1175mV)
800 MHz
925 mV (Stock: 1100mV)
500 MHz
900 mV (Stock 1000mV)
200 MHz
800 mV (Stock: 975mV)
So i dont know my Voltage group sorry guys , if this values are not working just go in 25mV steps lower from your stock voltage
until the CPU gets unstable or crashes than u know that u cant go lower just do this with every clocking !
I also used this voltages on XXLSC Ultimate Rom with the HydraCoreNirvana Kernel i had fantastic results too but not that good like i get with the Asylum CM 10.1.
PS: Just this Voltages wont give you very good Battery life if your Rom / Settings is/are eating your battery. If you get better results with
lower results (stable) just go ahead and post it but im sure this values are nearly the lowest stable u can get
Code:
Its [U]impossible [/U]to hard brick your device with Undervolting , you only could get a soft brick if you use (Set on Boot) and your voltages will crash your System after boot. thats easy to fix just after the phon booted up fast go into SuperSU and delete the root rights for your Undervolting tool.
Thanks for Reading and if i you liked this push the Thanks button =) !:victory:

Thanks man

I think you should say which Voltgroup (A, B or C) your note is. Because those freq are really low (I think too much low for my note, that's voltgroup B).
Do you remember which voltgroup has your note, when you installed hydracore kernel?

Better i would buy a spare battery rather than spoiling my devices performance. We arr not in 1000BC with no electricity. Sure every one can charge a spare and can switch it.

Hey there i dont remember never looked at the Voltgroup sorry so there is no other way to view my Voltgroup ?
Btw just try the voltages without autostart and u will see if your system reboots or if it works if not just go in 25mV steps higher :highfive:

Why ?
I cant get your argument my performance is the same speed while im gaming browsing same performance than before .. no impact , drops .. a spare battery ? So what about i dont want to switch my battery ? there is no need for it my battery stays alive for atleast 2-3 days when im doing something with it .

It's a feature of the hydracore kernel only I think, because its read a particular value (something about mainboard and/or cpu) and the kernel automatically apply dedicated undevolt values. You could see it in system information, where hydracore kernel is detected. Without it, I think you can't do anything :/
Anyway, sincerely I remember some time ago I tried to lower my already undervolted cpu voltages, and I got freezes. I will try to go lower a bit, hoping it will works. A very important thing, is not only the lower battery drain, but also the lower cpu temps.

I bought rom toolbox full sometime ago, when there was sales. If I remember correctly, there is a section relative to the cpu control, but I don't remember if it was undervolting capable also. You should start to search it from there (I'm sorry, I don't have the app installed anymore, so I can't help you properly... In case, use voltage control app)

What do you mean by Rom Toolbox doesn't have voltage control?
Tap kernel tweaks, then any frequency and you'll find a voltage slider in there.

Maybe it depend from the kernel I'm using now (philz 3.99 on BurtRom tw rom) but I can't able to do what you said. I checked on rom toolbox pro again, and I didn't see any uv feature. Just goverors/kernel tweaks (like vm or fs features) or profiles management... Nothing else.
Anyway I'm using tegrak ultimate app to Undervolt my cpu and gpu, and it works perfectly, so I don't miss so much that feature.

I don't know - I am not sure if Undervolting could hard-brick or damage the hardware but back then running GB roms I had undervolted FM Kernel and there was trrrr trrr trrr like sound from my Note.
Be careful.

I have to do a custom rom just to see if its all true....otherwise am not interested at all in undervolting my phone. Hope its true...

never had any problems and just logical cpus could brick if you give them too mutch voltage , if you give them less voltage the system only can crash your sound could have been beacuse it crashed so really u cant hard brick your device with undervolting ... maybe a softbrick if your unstable voltage settings are on autostart.

Hey there , you cant uv with Philz kernel just read his thread check his FAQ there hes writing that hes not supporting
oc/uv its just a repacked stock kernel
use HydraCoreNirvana but when you download the kernel check that its the OC version if not than you cant change your voltage like with Philz kernel.
:highfive:

Just use tegrak ultimate Overclock app. I bought it because I think it's the only who give you the possibility to Undervolt the gpu also. Initially, philz kernel wasn't supported, but now it is. I undervolted my cpu setting the values that I had using the hydracore kernel oc. And today I lowered them of another - 25mV also. Everything works nicely until now

Nice attitude you are showing there. Oh, there is plenty of power, let's waste.it! Really, that kind off attitude is definitely going to make the world a better place
What's more why do you think undervolting does influence the performance? It only influences the power consumtion and if you go too far it does render the phone unstable. But it certainly does not in-, or decrease the cpu's performance.

Yep tegrak definitely does the trick with PhilZ kernels. I have been using it for at least 8 months now and my phone is undervolted too. Only the highest cpu state is overvolted because I overclocked it to 1552 MHz instead of 1400.

I would love this kernel under ubls4 if it has a proper exfat support. Until this is not fixed like philz kernel, I can not test or try

Please explain why you overvolted AND overclocked the highest cpu state. Doesn't this shorten your batteries performance?

Did you changed cpu governor or something else (like screen off profile to reduce CPU) to achieve 1% battery loss at 3pm?
And was that with mobile data on?

I overcloked the highest cpu state from 1400 Mhz to 1552 Mhz because I want more performance. And because my phone became unstable with the 1552 Mhz and the standard voltage. So now my phone saves energy when the lower cpu states are active and it has a bit of extra power at the expense of battery life when it needs the most processing power. All in all that gives me better battery life than with stock settings and a snappier device when needed. For me this is the ideal solution.

Battery drain issues?

Hi
I was wondering why this was happening and what exactly is happening? I'm a noob at this flashing roms and kernel and duno why this would happen or what is it called?
See that major drop?. MY phone randomly reset for no reason and went from 9x% to 7x%?
Why?

This could be because a lot of things, you should provide a little more information about what you did to flash ROM or kernel, and would be nice some details about what you were doing when this happened.
Sometimes it is kernel related or because too much undervolting.
:good:

battery drain
I am currently using Paranoid Android 3.99.
I flashed franco 1.74.
I underclocked my cpu to 1000mghz
And i undervolted 75volts across all frequencies.
I wasnt doing anything processor intensive. I was locked my phone and tried unlcoking it and then it rebooted and drastically dropped my battery %. Since you told me it might be voltage issues i put the voltages back to previous stock voltage see what that does for me.
But do you have any suggestions on voltages to optimize battery life?
I just followed what I saw someone else said on a different post.

Well, it looks like and UV problem. Most of the UV related problems are easily identified because it seems that phone goes into deep sleep and then it cannot wake back, so the reboot happens. When you say that you locked phone and then tried to unlocked and rebooted, is clearly a symptom of this.
I would adivce that you first know which type of processor you have, there are 4 types I think:
http://forum.xda-developers.com/showthread.php?t=2052496
It depends so much in which type you have, because fastest processors can UV more. I have had UV -150mV with no problems, but again, it depends so much about your CPU's type.
Also, you said you flashed Franco 174, I think there is a newer version, and flash a JWR kernel because PA is now JWR based.

Mahdi ROM Kernel Tweaker & Battery Life Thread

Hey guys.
I have a clean Mahdi ROM (the latest from like 1 week ago) and have the feeling that the battery drains slightly faster than in stock. Apart from other things I started trying different kernel tweaks and I discovered the following:
The governor, although showing explanations for a whole 7 different modes, only allows me to either pick "interactive" or "performance".
Since I never really need the CPU settings from interactive mode, I actually want to use conservative.
How can I realise that now?
Please feel free to post your battery life stats, I'm really curious.
Sidenote: I have "transparent weather clock" on my homescreen and it seems to need a lot of battery. Does anyone have a recommendation for a lightweight & goodlooking homescreen widget?

The kernel for that ROM only contains two governors, please do not use performance because it only uses your max frequency, which is bad for temp & battery life.

Ok, thanks for the info. I wondern why it only contains those two though.
I'd never use performance, interactive already provides more power than I need.
I'm just looking for a way to actually use the conservative mode.

Something weird just happened to me: my phone was at about 38% and when I looked 1h later, it was pretty warm and powered off 1min later because battery had dropped to 1%.
I think this is pretty weird. I did not use the phone in that hour and had no apps running.
As illogical it might sound, my first suspect was the energy saving mode I enabled. I dont know why but I think it messed something up.
Does anyone have similar issues or any useful advice for me?

The developer believes those to be the best choices, I have no clue why. Interactive mostly stays near the max freq & makes my phone uber hot like an oven. Feel free to use Render kernel, its in the general section.

Nexus 6P only uses A53 cores?? Too low benchmarks

As above.
Daily use is very good, everything is responsive and fast.
However, benchmarks are roughly 50-70% of what they are supposed to be.
I tried to post a screenshot of CPU Spy, previously reseted timers and then ran BasemarkOS and Geekbench. (can't because less of 10 posts )
I see in CPU Spy that Max CPU state is 1555 Mhz? That's the A53 cores, right?
Is this behaviour normal?

Are you on Android N?

So what is the best app to monitor cpu activity?
And why are my benchmarks so low?

For instance, I'm only getting ~25k in 3dmark Ice Storm Unlimited, roughly the same as my previous Nexus 6.
According to Anandtech I should be getting ~36k.

Kernel Adiutor is a free kernel manager. I prefer using ElementalX Kernel Manager (paid app). Both work perfectly fine on Marshmallow, support HMP, and receive frequent updates.
If the phone is hot, then benchmarks will suffer. The big cluster gets throttled and goes offline whenever the temperature reaches a certain point. If it is running cool and you see low scores then idk cuz I don't do benchmarks.
Sent from my Nexus 5X using Tapatalk

If the phone is responsive and fast as you say why do benchmarks scores matter? Benchmarks are pointless, they give you a pretty useless set of numbers that don't equate to real world usage. If your real world usage is good (as you pointed out) then you're wasting time and energy worrying about something that doesn't matter.

I don't care about benchmarks, but they can point to a problem in your phone.
And I really would like to know how a phone sent to hardware testers consistently gets much higher benchmarks than the one I bought. Something's not right.

I've had eight of these and none of them have performed well in benchmarks. Take from that what you will but I believe it's a problem that's common to the SD810, not necessarily that you have a defective unit.

[GUIDE]Make kenzo/kate a battery beast!!

Hey guys. Just wanted to share some tweaks with which you guys can get amazing battery life on your redmi note 3. I used this setup for 3 full charge cycles, and averaged about 10Hrs SOT with a 1 year old battery, when I was getting about 5-6 hrs of SOT only on normal pie/10 roms. Do give this setup a try if you want the absolute best battery, and don't mind about performance degradation a bit... The device now behaves like it's got a 5000Mah battery now. If you guys manage a better setup than this, then do share your setup down below. And please hit the thanks button if this helped you. Cheers:fingers-crossed::fingers-crossed:.
SETUP:
Havoc OS latest 8.1
Latest agni kernel 13.0
Spectrum profile to battery
In any kernel manager (I use fk kernel manager):
.Big cores disabled
.Little cores max clock at 1382Mhz. Min clock to 400Mhz.
.Undervolt to lowest stable value (It's different for everyone, so try out a stable value for you).
.GPU max freq to 432MHz. Min to 133Mhz.
.Adreno Idler to on.
**Guys who have the 2gb kenzo, try the mcaosp 8.0 ROM instead of havoc. It has better
RAM management for you guys.**

Thanks a lot mate. You're setup is giving me close to 12hrs of sot, which is insane. I still can't believe it. Thanks man.

i will try, i dont care about android 10

Hey guys. Just wanted to share some tweaks with which you guys can get amazing battery life on your redmi note 3. I used this setup for 3 full charge cycles, and averaged about 10Hrs SOT with a 1 year old battery, when I was getting about 5-6 hrs of SOT only on normal pie/10 roms. Do give this setup a try if you want the absolute best battery, and don't mind about performance degradation a bit... The device now behaves like it's got a 5000Mah battery now. If you guys manage a better setup than this, then do share your setup down below. And please hit the thanks button if this helped you. Cheers:fingers-crossed::fingers-crossed:.
SETUP:
Havoc OS latest 8.1
Latest agni kernel 13.0
Spectrum profile to battery
In any kernel manager (I use fk kernel manager):
.Big cores disabled
.Little cores max clock at 1382Mhz. Min clock to 400Mhz.
.Undervolt to lowest stable value (It's different for everyone, so try out a stable value for you).
.GPU max freq to 432MHz. Min to 133Mhz.
.Adreno Idler to on.

Where I should get that spectrum profile?

It's an app in the play store. Link:

If anyone wondering, you can use Kernel Aduitor to disable cores and undervolting, it's free and it is quite comprehensive.

@shivaay1234 are you the guy who made that rapid os rom?

Oh cool. Bro, but why did you stop development of rapid os? I liked that ROM so much...

When Q sources become stable, I will release the Q version of the ROM.

I used to disable the big cores as well on a per-app basis. For light usage like listening to music or reading ebooks, downloading stuff in the background etc it used to yield tangible improvements in battery life. Also while charging to keep battery temp. in check. Now I have Tasker automate it all.
Funnily enough in Redmi Note 3 with only the little cores active device didn't feel much slower but in my Poco F1 whose little cores are much faster (higher IPC, 25% higher clock speeds) it would feel a little laggy with big cores disabled.
Its better to undervolt only the higher frequencies and leave alone/reduce only a little the lower ones as they are much closer to the threshold voltage and more likely to cause a forced reboot if undervolted too much.

@amn1987 Thanks for bumping this thread dude, i really needed to improve my SOT. Hopefully this will help.

Bear in mind the performance degradation can be quite noticeable. Instead of completely disabling the big cores maybe experiment with clocking them lower at 1-1.2GHz where they are most efficient in terms of perf./W IIRC. At these low clocks they will still completely outperform the little cores due to nearly 80% higher performance per clock.

SHADOW Kernel by @energyspear17
Already have QUAD core and battery mode.
You can also UV while flashing
Which would result in better battery backup.
Anyways different peoples different choices.
Good works?
