Hello,
I'm planning going on a trip soon, and I would like to use my i9300 as my main navigation device (both on roads and out in the field). Because of that I'm looking for a rom (or rom-kernal combination) that we'll have good battery life, functioning GPS and good internet reception. So far I've tried several roms from the website (all CM based), but suffered from severe battery drain.
Can you please reccomand on a simple, battery saving rom for my purposes?
Thank you very much!!

We can't discuss ROMs here, but with any kernel that comes with an configuration app you can change the voltage, CPU governors and I/O schedulers, enable or disable zram (obviously depending on the kernel)
On xda there's a topic that shows the differences between CPU governors. Also you can try changing it yourself. They will determinate how much battery your device will eat while active. Obs: zram can give you better memory management, compensating the lack of physical RAM but will DRAIN your battery (like seriously, without zram I have +5h on my battery - low/normal usage)
@mk010: I recommend NCS-ROM: all sensors work optimally, no surprises in unknown environment. For long battery live try (in BoefflaConfigApp) governor zzmoove /profile battery plus.

Don't worry, this is not a what is the best kernel question. However it is similar. I have tired all the kernels, speed mod neak redpill syihah phenomannal. With certain kernels such as neak, speedmod, phenomanal, high get a really high Android OS usage. I have read this is just a reporting error however it seems the battery drains alot when in standby. This is not a waklock problem because i dont have any in the battery usage graph and in better battery stats. Does anyone know how to eliminate this in speedmod as it is my favourite kernel.
My last question is what is the best kernel for standby battery drain, i only use my phone around one hour of display time per day. With speedmod i drain around 3 percent a hour without doing anything and again their are no wakelocks.
If you could provide any insite that would be great.
Thanks
It depends too many variables can affect stand by, type of data your on, your signal strength, and such. Only true way of finding it out is to experiment with different kernels and governors. Try use a governor which sleeps well like lulzactive or similar. They have suspend profiles when screen is off, or can achieve something similar with setcpu and setting a screen off profile with conservative.
Allows a good few charge cycles to judge its performance as battery settles.

Yeah i use the KL1 modem with redpill then one im using right now their is only conservative ondemand hyper and sleepy which is the best for standby
I can't answer that as not used that kernel I myself use only ondemand and works out fine for me. Try out conservative and see how that fares.

Ok but can anyone speak to the high android os usage?
Anyone?
After testing several kernels i found that SIYAH 2.6.9 for Gingerbread and Siyah v3.0beta6 for ICS are tremendous on standby and you can see the low Android os consumption (varies between 3% to 10%)
for me siyah workd well with very less andriod os drain but the newer versions ,i am not satisfied cause its heating up more...iam experimenting all kernels ,i was on redpill latest and it workd well,wivout any setcpu,gov,tweaks etc...since 3 days on saiyah 2.6.14+ an its giving good results like the os drain is less than 10.....an iam not on any gov ,tweaks but ill b trying uv,gov twek .....
and yes for reminder iam heavy duty wiv 385+ apps

Its simple different people different phone usage different kernels for different peoples usage .
its usually user apps that are background drain .

Do not have much experience with the galaxy ace roms, so I would ask those who already know the other roms for the existing model because I'm using the Cooper CyanogenMod 7.2.0 RC1, but I'm not satisfied with the battery consumption of it, for to enable wifi or mobile data network consumption is absurd. What is the best rom to have an adequate intake? Since we do not use the phone for games except ninja fruit and angry birds.
If you have any tips to improve consumption, without the basic features off when not using, I thank you.
For best battery, switch to stock DDKQ8
are you often with no signal ? i also had several battery drain in CM7.2 FAT till i found it was due to low signal. now whenever i'm in a place with no signal i just turn on the airplane mod. the phone has been unplugged 4 hours and just consumed 5% battery witch otherwise would be 60% or something around
The biggest battery drainers in order:
-screen. So lower brightness.
-3g/2g switching and downloading. If bad reception, try sticking with 2g (more than enough for messaging, not enough for browsing). Also a firewall to keep apps you don't want from sending/receiving data.
-WiFi. Music (even on headphones) and other interactive apps (games and such)
Also, stock roms yield better battery at the cost of performance (cm based roms are more powerful usually). Ddkq8 has given me the best battery out of all stocks for my everyday use (3g all day, some browsing, lots of whatsapp and music, no games)

look here, dude: http://forum.xda-developers.com/showthread.php?t=1447938
Hi all!
I premise that I'm quite good in modifying PCs: for example I successfully undervolted my HD5870 Mobility by flashing VBios.
You are not talking with a complete noob, I know what is undervolting, flashing operations (in PCs) and so on; I simply need someone who can teach me what to do, because I entered smartphones (and Android) world 2 weeks ago.
My goals are:
- Reducing temperatures
- Increasing battery life
- Rock Solidity in every condition
- Increasing my "skill" and create my own voltages pattern, I don't want a "pappa pronta", as we Italians say.
I don't now if it's possible to modify the original kernel. If yes, is root access needed?
Which applications are necessary?
Thanks ahead.
Luca
not possible with stock kernel
- Increasing battery life

Undervolting too far will actually result in less performance and higher battery usage. Even if the phone's stability seems unaffected it may have calculation errors or unfinished calculations at the end of a cycle so it will have to repeat them.

My S3 randomly reboots with only 25mV undervolting. It seems to happen when the 3. CPU-Core is powered up. (But as soon as it's online it won't cause crashes)
There is a reason for Samsung setting a CPU voltage. That reason is physical limitations of electrical patterns and power loss and manufacturing instabilities.
If you're unlucky you cannot undervolt at all, if you're lucky you can go below -100mV
Thanks to both. I'd like to try... Battery life is secondary, my primary goal is to decrease temperatures...
Eden only a -25 mV would be appreciated!
Can you help me ?
Just flash Siyahkernel ( http://gokhanmoral.com/ ) and install the ExTweaks apps (free) from the Play Store. It brings everything you want/need and some more.
It also includes Root so your warranty is void when flashing. (At least in most countries...)
(Th wrranty would be gone anyway as soon as you tinker with the kernel)
And what about:
http://forum.xda-developers.com/showthread.php?t=1728758
?
(I know this kernel can't be modified)
You can flash any kernel you want thats for the i9300 and supports undervolting.
Which one to choose depends on your preference and feature requirements.
I know alot of people ask which is the best combi, but i dont care about that.
im wondering which one really affects the battery more, the rom or the kernel?
im looking for more battery life and i constantly try many roms and kernels to find the best, but its all very erratic so im wondering which one i should change and look for increase in battery life more
tks
It's a combination of both. The core power management drivers lie in the kernel, along with CPU frequencies, governors, and other battery life affecting things. But the ROM is what ultimately makes use of the kernel. If the ROM has certain battery draining features, then it will affect battery life negatively and vice versa. So it's really a combination of both.

Hello folks!
This thread is intended for sharing, please be kind. Any suggestions would be appreciated
A few days ago I was tired of having my Mi3 running on stock global dev MIUI 8, it was inefficient system with really bad memory management. On my experience, the MIUI tend to run out of memory. In some case, after a few hours of usage the system cannot reclaim the occupied RAM, thus making the system lags a lot and generate excessive heat!
Yes, MIUI is a feature-rich ROM, and the Mi ecosystem is a pretty mature ecosystem. However, those all greatness needs a lot of power to run on our 3 year old device. After a few research I decided to switch to CM13 ROM.
With efficiency in mind, I do my research and tinkering with my device to get the best setup possible without losing performance. The results are AMAZING! I can use my phone for a whole day without recharge in the mid day. All of this with huge improvement on performance, Real Racing 3 highest graphic setting without any noticeable lag! CPU and battery temperature are now significantly lower (43-47C idle / light tasks, 55-57C heavy gaming). Now that I've found the best setup, I want to share it with you folks! Here we go:
Mi3W 64GB
CM13 ROM snapshot build
CM kernel (automatically flashed while flashing CM13 zip through TWRP)
Screen resolution changed to 720x1280 use this guide
Modded interactive CPU governor (see screenshot below)
Undervolt (see screenshot below, this one really helps reduce CPU working temperature)
Noop I/O scheduler
Reduce aggresiveness of LMK (see screenshot below)
Thats all folks, hope this guide will get our Mi3 having another year of flagship-grade experience! Cheers! :highfive:

It depends on the kernel used. Cm kernel that he used supports undervolt. Careful when undervolting though as too much of it can cause cpu instability and reboots.

Yes, it depends on the kernel used. Some kernel support undervolting while others don't. You need to flash kernel that support undervolt.

While testing CPU voltage value, don't tick "apply on boot" option until you find the most stable voltage without causing system reboot or crashes. Every CPU has different limit on how far you can undervolt, but you can use the values on my screenshot as guidance (Snapdragon 801 / MSM8974-AB only)
Wow!! Thanks a lot bro. I'll fiddle now with my phone.

Undervolting (and clock adjustment, in general) pretty much is a case-per-case basis, so different handsets (even if it's the same type of device) may have different setup. Try lowering it first incrementally and test it, until you have it stable enough.
