[Q] Flashing unity kernel + battery life

Hi all
I've unlocked the bootloader on mine through the htcdev site and am currently running Niks latest rom.
However after flashing Nik's latest rom, I'm finding that my battery life has been horrible (i very much doubt its the rom, lots of people have commented on great battery life with his). Can just scrape through a full day's use of texting, some web browsing and music playing. After some browsing on the phone, it goes down from 100% to 90% in about 10mins I've tried increasing my battery life by following the method found in this thread http://forum.xda-developers.com/showthread.php?t=701567 but it still hasn't worked for me.
After reading the forums, I've heard that unity's kernel supposedly brings better battery life and am considering flashing it. However I'm not sure if i can flash it given that I haven't rooted my phone or done an s-off?? Can someone please give me an answer on that?
Also, is there anything else I can do to increase my battery life?? It's so annoying having to impose restrictions on myself to increase battery life when my friend's S2 drops to 98% after some browsing and 3 hours of standby...
Thanks so much guys

sometimes, a custom roms make your baterai drain fast.
why? so many tweaks and overclock at cpu.
so, you have other options to change your custom rom.
example, ARHD 2.1.3 make your baterai not drain fast.

If you don't have full s-off, then you are restricted to whatever kernel comes with your ROM. I'd recommend you look into SetCPU if you haven't already, which will improve battery life by regulating how your processor is used. Juice defender is an app worth looking into as well. Have you tried flashing an earlier version of the ROM? Sometimes you can get a build where the kernel just doesn't work well. You might find your battery life improve with an older version, with a different version of the kernel. You have nothing to lose by trying I guess.

As man, not the answer I was hoping for. Thanks for the info, ill give that a try and see if battery life improves. If not might go the whole stretch and get an s-off

[Q]Best SetUp for my daily use ?

Hello !
I use my M7 for chatting, navigating, phone calls, some apps like "amazon", bus connections etc. No heavy gaming or other projects.
I have even underclocked it to 1100MHz for better battery lifetime.
For me it's important to have a fast, Stable Rom with a great Battery Lifetime. I don't care about its design etc. but it should be Sense.
Maybe the battery lifetime isn't related to the Rom (read a big discussion about that, but didn't finish..). In this case, what Kernel can you recommend ? Any mods or settings ? Any apps or possibilities to get the most stable Rom setup, with good battery life time ?
I don't need fancy designs etc. Just want the phone to be fast, and stable. And of course a good battery lifetime.
Any recommendations or tips ?

well my recommendation will be to try some differents roms and kernel yourself and see whats work the best for your needs.
no ''what is the best roms/kernels" threads are allowed here.
see below forum rules:
What does not go here (by far an uncomplete list, just some examples for topics that are not tolerated)
(...)
"Whis is the best rom for this device", "Is this rom better than that" (always subjective, prone to fanboy wars)
(...)

apart from the rom/kernel, I personally use Tasker to set custom power saver profile, you might want to give it a try (this is a paid app)

sorry guys , recommendation threads aren't allowed.
thread closed.

Kernel for Battery Life HTC ONE M7

Can anyone suggest me the best kernel for battery life in your opinion?
Im not looking for feature, just performance and battery life..
Thanks before..

Had you followed the rules you would have found that it all depends on your personal setup. The apps you have installed, settings you have set up, Area you live in and even how you use your device all effect your battery.
A search would have told you to try them all out and make up your own mind.

Got a new N6, Which ROM/Kernel do you recommend ?

Hey XDA,
my Z3 broke and my insurance gave me 500€ to get a new phone so i got the Nexus 6 32GB Blue for 490 € at my workplace.
Before my Z3 i had many different Phones like the S5, LG G3, NEXUS 5, HTC ONE m7 and more
Well what mostly use me device for is communication, A LOT (LOT LOT³) OF Fn READING (Manga and Reddit Sync) and hearing my music on the way to school/work/whatever .
I am a experienced user with roms and flashing but with this new device i just want to flash something daily driver friendly but feature heavy rom and a good battery conserving kernel
So far ive looked around for some roms available here and already choosen the
CHROMA Rom because it seems to be popular here (Not sure why ?!) (What is "Layers" ?)
and the Vindicator Kernel because it looks very promising (Not sure if its the case tho) and it has a lot of features (for a kernel..)
So what do you guys use and show me some screens of your themes becuase i like the possibilty to use the cm theme engine
Thanks

For stability.. Chroma/hellscore kernel
Or use the JDX based on latest android M which is pretty stable too but you may encounter few bugs

"Best" ROM.
There is no such thing as a best ROM. The question itself is ambiguous. "Best" is obviously a subjective term.
What I want from a ROM may well differ from what you want from a ROM, ergo - what is best for me could be worst for you.
If you are asking what the most popular ROMs are, or which ROMs people are using, you can see which threads stay around on the first few pages (and have the most posts) in the Android Development or Original Android Development forums. You can also see what other people are running by reading the What are YOU running on your Nexus 6??? thread.
If you are asking which is the most stable, being a Nexus device - they're all pretty stable.
If you are asking which is best on Battery, ROMs only affect battery if they have a feature that is badly coded. You will likely be able to read about this in the ROM threads. ROMs do not impact battery life. The only impact to battery life are your apps, your settings, how you use the phone and mostly, environmental issues such as Phone Signal.

"Best" Kernel
There is no such thing as the "Best" kernel. What we all want from a kernel is different. Again, many people have the misconception that Kernels affect battery life. Let's get this cleared up. Although Kernel devs will build in optimisations and efficiencies that will improve battery life, these are very, VERY tiny...and if 1 kernel has these optimisations, they likely all have.
People will often say "Kernel x is better than kernel y for battery life". This is actually wrong. Kernels respond to user settings. Setting up the governor to favour either battery life or performance is simple enough to do, you just have to do some learning. The reason people think Kernel x is better than y is because developers set their kernels up with their preferred governor settings. This is what we refer to as out-of-the-box settings. The out-of-the-box settings for kernel x may well produce better battery results than the out-of-the-box settings for kernel y, which favour performance. The fact is, you as the user have the ability to tune kernel x or y to perform the same, be that battery or performance - so start learning how to do this yourselves - that way, you can choose the kernel based on the FEATURES you want, and not the fictional performance benefits of one kernel over another.
Hope this helps

I never asked for a best rom/kernel.. just your recommendation and im sorry that i didnt see the other thread you showed me
Do you have a tutorial for kernel settings ? because i didnt have a nexus for a long time now i never messed with kernel settings that much
And what is your opinion on my choosen rom/kernel ? what are you using and why ?

No worries, but recommendations kind of fall under "best" in a way anyway and it is all subjective.
FWIW, I like to use Slim Alpha and ElementalX kernel.
As for tweaks, it all depends what you want. Performance Versus Battery. Easiest thing to tweak is the governor settings. Some governors will allow you to change the Up Threshold. The % of CPU load before it steps up to a higher frequency. Set the up threshold high, it will stay at a lower frequency for longer, of course that impacts performance.

Well i am thinking to go battery but not 100%. but more like 80%
Problem is i dont know what the apps need to work fluid (or not?)
With recommendation i meant something like this
"AWESOME DUDE, I HAVE A NEXUS 6 WITH ROM X AND KERNEL X AND USE IT FOR DD AND LOTS READING
ITS WORKING LIKE A CHARM NEVER hv HAPPIER BEFORE BECAUSE THIS DOES THAT AND THAT DOES THIS"
sounds stupid, i know but maybe someone else using the N6 is in the same scenario as i am.
Got some good news 3 hrs from now i will hold a fresh Nexus 6 in my handy and now someone is offering me a GS6 32GBlack for exchange xD
GOT IT GOT IT GOT IT earlier but happy about this new awesome toy to play with

Battery life OOS 4.5.1

Hi guys im looking for kernel with the best battery life, which one would you recommend for me? Also how's your battery life on oos 4.5.1?

There we go, another "what's best" thread.
The most accurate answer is you have to test it for yourself. Everyone has different usage patterns.
I won't send my usage screen since I never drain my battery to 0%.
Boeffla, ElementalX, franco, Flash... there are few of them. Just look them up, download, flash and test.

That's what I want to do but maybe someone has tested already ?

In my view,
1) Franco kernel is the best if you use your phone not for the full day because practically I do not see any drain of battery in sleep mode.
2) Blu spark kernel is the best if you want to customize the clock frequency as it is compatible with Kernel adioter app which is free. In Franco as well as in Elemental you have pay for their compatible app.
3) ElementalX kernel is the best, if you use your phone daily, then you can customize the clock frequency and other stuff in aroma installation while flashing.
Now, it is up to you to choose.

There are already so many threads like this. We don't need another. That was why he said "another" best kernel thread.
Expected others to do the testing for you is pointless. There are too many variables regarding how you as an individual use the device. So testing under your particular usage conditions is the only reliable indicator.
