Been using the Vibrant for 2 whole days now on the Macnut R1 ROM. While looking through the Dev forum I noticed a lot of terms when talking about kernals (JPA,JPO, etc) Can someone shed some light on what these terms mean? When I look at the kernal in my phone info it says
The reason I'm wondering about this (aside from gaining knowledge) is because I like many am on a quest for better battery life. I see a lot of people in ROM threads saying they get better battery life with this kernal or that kernal and I'm not going to start flashing until I understand it all. Thanks in advance for the help!
Is XDA acting up or something? Your thread title is Duplicate Pictures but nothing is to do with pictures in this thread?
Also you said in your phone info it says.............
...........says what?
For battery saving and maximising up time, it seems to have a lot to do with the first 100% charge, although i heard and did 5 full charge/discharge cycles when mine was new and also to do with how you run your phone, i.e Live Wallpapers(they eat power) task killers(a waste of time as the system just fires them back up again anyway, so you end up killing, starting, killing, starting processes).

That's a thread on battery usage and there are some tips in there too
As for specific ROM battery usage, you'd be better reading in Android Development, go through the threads concerning any ROMs you like the sound of and look for people reporting their experiences. A good tip though is to avoid the ROMs that aim to increase processor speed as that's going to cost more battery and generate more heat
The title error was my fault. I was typing about one thing and thinking about another. -_- To complete that sentence my kernel says 2.6.32.9 [email protected] #45 which is apparently a JPA kernel.
I've been hanging on the dev forum and I did gain some understanding there but never found a clear explanation about the whole kernel thing.

Hello,
I'd have posted this to the dev section but the posting rules here require non-talkative people to fabricate 10 useless posts before they can post there.
I've noticed that "Cell Standby" is far and away my greatest battery user on my Nookie Custom 0.6.8 eMMC flashed device. Now, I'm sure this is just a mislabeled "Display" usage meter, but I wanted to make sure. I'd post a screenshot, but apparently I might be a terrorist since I haven't made ten posts yet so I'm not allowed to link images yet.
Thanks In Advance
As far as I know, the cell phone battery usage problem has been debunked. I could be completely wrong, but since the Nook lacks the necessary components, there's no actual way for the power to be lost in the process.
I'm about as new as it gets, though, so take that with a grain of salt.

Yep, it is debunked, ignore it if battery life is the concern. If you want different info in Spare Parts for partial wake, this changes it to Android System..

I believe this, however -- how hard would it be to find an app that claimed to track what was using the battery with any accuracy. Pretty sad that the built in battery monitor gives "credit" to "cell standby" for 50%+ of battery usage on a device that does not even have a cell. Anybody could build an app that hard coded battery usage stats in pre-defined chunks
I don't know why this bugs me so much...it just does.
Hello everyone,
I'm running some tests to see the battery consumption on my Galaxy S i9000. I'm using the gingerbread version of darkys ROM.
Firstly, what do you think of the battery life? In this specific test I used the phone in a very light way, made some messages/calls and read few mails.
Secondly, is it normal to have depressions in the battery chart that display less battery than it shows later? How is it computed? Isn't just some logic level of the voltage battery?
Lastly, in the case of buying another battery, is it worthless to be genuine?
Thanks a lot
I have same qestion like you, in the another thread....

Sorry! Obviously I didn't searched properly. Hope someone can clarify us
Is it a gingerbread issue?
Even big batteries will "recover" after heavy use so ur graph is quite normal.
Also be aware that if the battery calibration isnt xorrect then that will lead to weird graphs too. E.g. Losing 1% over 8hrs after flashing a new rom is most likely due to inaccurate battery calibration.
Sent from my GT-I9000 using XDA App
When I install a new rom the battery stats are always deleted? Or it depends?
I also having the same prob...batt consumptions are always the main concern when come to flashing a new rom...Darky's can only last me for 1day with heavy usage and recently flashed to MIUI which can only last for <8hours with the same usage...im not sure why this happen but I am trying with different kernels and see which is the best combination...
I just installed a new gingerbread ROM and guess what.. Using push, wi-fi all the time, gps, 1h youtube video, sms, video call... The battery never ends!! As I'm writing the battery is still 15%. It's amazing the gingerbread in terms of battery consumption. Obviously, something in the other ROM was not right! Guess I'll stick to this battery a little more time.
Btw, the battery stats are pretty normal, no depressions..
I found a thread with the battery life for different captivate roms, but they are all old versions of the roms . Can we update that thread with the latest gingerbread roms? Or maybe people can write a comment on this thread saying what rom they got the best battery life with? I am not in my house for around 13 hours a day on weekdays, and I use my phone extensively, so i rely heavily on my battery life getting me through my day and that is why I would like to know what rom, gingerbread preferably, has the greatest battery life. Thanks!
Its completely irrelevant as your battery life will differ from anyone elses...
Threads like this are generally discouraged as they nearly always result in petty squabbling.
Hey guys, just picked up the nexus six and am writing this all out on it right now so excuse any errors. I just have a few questions about what to expect from rooting this device/Roms in general. Roms for the device anyways...
So I've heard encryption slows the phone down by about a 50% mark and am curious as to peoples experiences before and after decryption. Does it truly feel to you that your device is 100% faster? If so, what makes you say that? The phone feels plenty fast to me at the moment, but I'm always interested in a little more...
I've also heard about the horrible battery life of the phone being caused by a sensor_Ind wake lock, among other things like the large screen and resolution. Has anyone experienced long enough to prove its not placebo, a noticeable, or even dramatic increase in battery life because of a ROM/kernel/theme. If so, what ROM/kernel/theme helped you the most?
And lastly, has anyone tried any of the more experimental mods out there on this device? Such as adding multiwindow, or blinkfeed? If so, how did it work out for you?
I'll be trying a lot of stuff while here so I'm just curious to ask the others out there how things have gone so far for them.
I am stock rooted and still encrypted, and phone is plenty fast for me. I have never unencrypted, so I can't compare the two. Currently I'm running Franco's r10 and the battery drain in deep sleep is incredibly small, and it is smooth as can be. He has done a good job on this kernel. I don't really have an issue with the sensor_ind causing excessive battery drain, but I don't monitor that kind of stuff constantly. I have uninstalled my battery monitor apps, as I find I don't need them because my phone will last me a couple days on 1 full charge.. If my battery life takes a dump, then I'll re-install them and take a look.
Is encryption worth it? A couple days is a sweet statistic though. I'll have to root soon and throw some stuff at my phone, hopefully grab one of the odexed Roms that are available as I tend to lean towards em
So far battery life to me is about 4 hours sot which isn't horrid. And I like the speed but the jitters on occaision bug me. I love the touch response on this display though feels like butter
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

Wow thats an awesome and big post with a lot of tought from you, thanks
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
