Is battery life.better on 1.3.2? I am using gokhan 2.3.7 with unnamed 1.3.2 at the moment. Are there any advantages to new unnamed Tom?
Sent from my SAMSUNG-SGH-I777 using XDA App
UnNamed v1 is KH7 based while v2 is KK6 based. That being said, 1.3.2 won't have the battery drain issues associated with KK6 that v2 will have. Entropy512 details the KK6 firmware bug a little bit in his known identified battery drainers thread.
Nitox, i saw from your signature that you are on 1.3.2. I work in a place that has low signal and usually prefer to stay on wifi all day but I have noticed more drain on wifi than on data. Have you tried 2.2.1?
I'm just debating if I should go to the KH7 version of unnamed.
Any opinion or imput?
I did switch to v2 when gtg released it, but ran into the wifi associated battery drain issue every once in a while (which drained 6-7% per hour overnight). It was stable for the most part but I decided to revert back to 1.3.2 to avoid the issue entirely, especially since I didn't notice any real functional difference between the two.
Solution to your problem maybe?
Interesting thread... so should there still be wifi drain if we install 2.2.1, but then flash the KH7 modem on instead? I personally see quite a bit of wakelock with this setup but i don't know if it is more than is normal.
I guess I dont really understand whether KK6 is somehow built into 2.2.1, or if it is a completely separate entity that just comes with the rom.
Every ROM is based on a certain version of Android (KH7, KK6, etc). What this means is that the developer creates the ROM with that version installed. KH7 is the version of Android that was shipped with the phone, so everyone who bought the phone was running KH7. So at the time that gtg first started developing UnNamed (ie. UnNamed 1.x.x), he was building his ROM off of KH7.
After the KK6 source was leaked, he finalized v1 with UnNamed 1.3.2 and released UnNamed 2.0.0 based on KK6.
I don't think the KK6 bug is modem-related: I'm actually running the KK6 modem on 1.3.2 and haven't come across the wifi bug. I don't know much about the root of the problem, but I'm assuming it has to do with some coding issues within KK6 itself. This thread has some more details about the bug.
[EDIT]
I'm not going to pretend like I'm an expert on the bug. In fact, I know barely anything about it, besides the fact that it exists, is KK6 related, and that I've experienced it before. Reverting back to 1.3.2 was mostly just me heeding Entropy's advice to abandoning KK6 and avoid the problem entirely.
[/EDIT]
Correct me if I am wrong but here is the way I understand the versions. There are three variables at play here: the modem (KK6, KH7, ect.), the Android version (2.3.4, 2.3.5, etc.) , and the kernel version.
I asked about WiFi performance in another thread in Q&A and Entropy responded saying WiFi is controlled by kernel and Android version. The WiFi bug is actually associated with the Android Version 2.3.6. Avoiding rom's based on this version will ensure you do not encounter this bug.
I currently have UnNamed 1.3.2, which is based on Android 2.3.4, running Entropy's latest kernel and I have had better battery life than compared to running 2.3.6 based roms (UnNamed 2.2.1 and SHOstock 1.8.1).
My advice for best battery performance: find a rom based on Android Version 2.3.4, flash Entropy's latest kernel, and choose a modem that works best in your area.

I'm fairly sure it's a bug with only samsung builds, namely KK6

Yeah it's a samsung build problem but what I mean is that it's a bug that is found in the Android 2.3.6 build provide by samsung.
Thanks everyone, it all makes sense now! Especially great explanation by nitox.n2o ... still trying to figure out how to use the "thank" function in these forums
Ill try 1.3.2 and see if that helps with my wakelocks! Its probably also due to the fact that I have poor reception at work and my phone is trying to constantly trying to find the best cell-tower to use
Hi guyz,
I have simple question here..Im using ST15I - unlocked - rooted- with custom kernel and ROM..I want to know that is it possible to flash a custom kernel and the stock rom..?
Is battery life depends on the kernel or the Rom.?
Because every custom ROM which I tested was good...but after few days it gave me problems like getting slow,Force close,freezing touch screen,stuck menu's,..etc.
So I wonder if there any chance to use a stock rom with a custom kernel for better performance..?
tnx
Sure, there is an option to use stock ROM and custom kernel, but they have to be compatible. I'm afraid any of CM kernels will work on stock ROM, but there's plenty of options - Lupus ICS, Extended stock kernel, MESA etc. And yes, battery life depends on kernel. Some of them are battery friendly, some of them not. But in general any custom kernel should work at least the same time as stock one (from my experience).
Bt battery life is also depended on ron, apps,3g, wifi and usage and a bunch of other things and yes depended on kernel too.
Yes stock rom and custom kernel can be done if they are compatible

Thank you gyz.....
Hey,
I installed a lot of roms but the battery was bad in the all roms\:
I installed Nitro script but the battery don't improved
I was did calibrations and then the battery don't get improved..
What I need to do to improve my battery?!?!
I'm very sorry about my English
I have JustArchi rom KitKat 4.4.4 omnirom v2.3.2
Use the search facility for the usual things to try.
You can tell me how to do that? Im not very good in android..
Hi,
previously I was on Sony Xperia devices but now I switched to Samsung S9 +.
The first thing that struck me is the bad battery life.
I've been reading on how to solve this and I will at least do a full reset and clean install to see if this helps.
But if this does not help I want to know what to try next.
CUSTOM ROM
For what I have found the custom roms do not use the second camera and that's something I do not want to lose.
So are there Custom roms that keep the original functionality from the camera?
CUSTOM KERNEL
If installing a custom rom isn't the way to go, what about a customer kernel?
So far I found two of them
ElementalX
Nemesis
And there is one html with an explanation about the speed and battery usage of the Exynos chip.
https://www.anandtech.com/show/12620/improving-the-exynos-9810-galaxy-s9-part-2
There is speculation whether Samsung will do something about battery usage as there seems to be a solution if Samsung does some ROM changes.
For now I think installing a custom kernel is my best option but what about OTA.
Once rooted I will not receive them anymore, can I just download the now ROM from Samsung and install it over the existing one without resetting the phone?
And once the ROM is installed reinstall the custom kernel?
I'm open to other suggestions to improve battery life.
Hello,
My warranty is over and i would like to root / change rom for better battery.
After oreo/marshmallow update i can use my phone only few hours. Got new battery from offical lg service but nothing changed. (Factory reset has been made)
Mostly i use my phone for audiobooks, texting/call, web and sometimes i play hearthstone.
To get better SoT what should i do ?
Stock rom with root and kernel tweaks
Stock rom with custom kernel
Custom rom with custom kernel
Or just simply downgrade ?
