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.
I had to come back to the custom rom world as I tire of the boring theme layout on froyo. I'm staying FAR away from Darkys rom because it does my battery wicked. I went with Jim's rom and although it is better with battery life, it still drains.
Can anyone recommend a rom that is simple yet closer to stock battery life? It doesn't have to have a million features, just something that will allow me to change the theme.
I'm on 2.2.1 xxjpy Froyo. Any suggestions??

Try one of the 'slim' ROMs, such as Insanity's. Removes a ton of the nevessary apps.
You won't get too much more out of the battery. Most roms eats the same juice while you're playing browsing, etc. The only difference is on idle battery drain. I use my phone on max. brightness since I bought it, and display uses min. 80% of the battery.
I'm using doc's customer ROM from kitchen with lagfix, and I usually charge battery once a day.
Thanks for your replies guys. I shall try out another rom until i find one that is manageable for my daily use

If you think stock is better on battery why dont you just download a stock Deodexed rom from Here and just install what ever theme you want.
I'm staying FAR away from Darkys rom because it does my battery wicked.
If you been on a deadly rom then it needs a complete wipe from phone battery stats reset and it will take the new rom a couple of weeks to sort itself out battery wise . Multiple problem posts on his rom litter this board .

I have good experience with criskelo's rom, but at the same time use a SuperPower application first of all for quick switching between 2g and 3g, saves a lot of battery.
I am using Samsung Galaxy S i9000. I am planning to change my stock ROM[GB 2.3.3] to either CyanogenMod 7 or SURFACE v8.01..??
Which one should I switch to..?? I need better battery life and performance than the stock ROM.
have you tried SAUROM
Hi
Since 2 yrs i am using different roms on my I9000 now I am using SAUROM rom i saw it's one best rom currently no fc's with many options you can try if you can link...http://forum.xda-developers.com/showthread.php?t=1388342
Hi,
I got my Galaxy S since one year now, and after the first month, I discovered the joy of installing roms ;-)
I tried many many roms (probably 80% of the roms here) and my impressions were :
I was very impressed by Surface (stability, battery, smoothness)
but it has been beaten by Cyanogen 7 because of many features brought by CM and making the rom very comfortable to use.
I stayed quite a long time with CM, then I restart trying mods (because I wanted to have a full GSII look, but no GSII looking roms was stable and smooth)
So before coming back to CM7, I decided to try MIUI as it seemed to be as popular as CM7, and I falled in love with MintBerry 5see thread http://forum.xda-developers.com/showthread.php?t=1350763)
I am completely stuck with it, and does not even want to try ICS roms because I am VERY happy with it for MANY reasons : stability, speed, tons of features, incredible dozen of wonderful themes, and best of all, all updates of the rom/themes/kernels/... are managed with a tool included, so you will not need anymore to play with odin and flash yourself.
Don't rely on the screenshots of the thread, because they don't show the magnificent themes (wood, metal, neon, dark, paper, pencil drawing, ...)
Have fun with the roms anyway, because it is great
And to avoid to loose your apps and have to re-install all of them, I would warmly recommend you to invest in titanium backup pro, because with it, you can backup your data AND the app included, so as soon as you flashed your phone, just "restore all", and after 10 minutes, all your apps are back with all their data and nothing else to re-install ! A pleasure !

Try them both and take your pick. For CM7 I can highly recommend Insanity CM 057 from nitr8 (very light and fast). There is also (CM9) ICS S.U.R.F.A.C.E. v1.1 just released (based on Theamhacksungs Build 11 from Pawitp)
For the better battery life of the two, go with Samsung ROM's like the suggested S.U.R.F.A.C.E. v8.01 (based on Samsung's very latest XXJW1).
happy flashing!

CYANOGENMOD 7 works just fine
---------- Post added at 10:19 PM ---------- Previous post was at 10:16 PM ----------
it is you decision both are working realy good
Well to decide its better if u try both i tried cm7 once it great and very fast and now I'm testing surface which is also great and until now it has a very good battery life you can check my video on surface

For better battery life,dont touch anything related to CM.I think this whole CM thing is hugely overrated.My experience of the CM roms are disappointing to say the least.
I tested so many roms,every time the stock rom with Galaxian kernel beats the custom eye candys.Either way the battery life on SGS is a joke.no matter what rom you are in.I always wondered why people testing the new phones phonedog etc.
are happy if the battery lasts a work day.Thats horrible.Maybe im just used to my 6 year old nokia with original battery can handle a week.With extensive call usage.

This is a question of choice, you cannot compare
If you prefer autonomy, go on with a normal phone, if you prefer features and apps, go on with the smartphones.
Tell to a 4x4 Mercedes user that you prefer your moped for the fuel consumption, same thing, this is not a correct comparison ;-)
Anyway, with normal phone usage, galaxian kernel and surface rom, my battery lasts 3 or 4 days, which I cannot do with stock rom.
only tried cm7 and miui, and i get about 20 hours batt life.
i remember using darky's (10.1 i think) which lasts about 3 days, couldn't say if i used my phone that much back then
Why don't you just flash them and make your own mind up?
I used darky 10.1 for ages and could get most of the week out of it with wifi on with the galaxy live wallpaper. I'm using Surface 1.1se at the moment. I tried Surface 1.2 - the base worked fine but the essentials pack broke my home button and lock screen.
For better battery life, go with Surface v8.03.
darky 10.2 re very good and jetpack v8.2 really good
I recently updated my Galaxy Note N7000 with the latest Indian firmware... DDLSC.. But after the update, I am facing a lot of battery issues. The battery does not even last for a day. It used to be much better with the older firmware(ICS). Please suggest me anything to get maximum battery out of my phone.
I am willing to install any latest firmware from any other country as well. It is not a problem or any other custom ROM that will solve my battery problem! I really need a lot of battery backup for my phone as I am mostly out of my house.
Please help me!!
Battery is always aproblem wif the note... i suggest take a look at ebay they are offering a double battery bank for 2300 inr.. that will really help u to get battery as they are giving out a batterry of 5300 mah. I personally dnt think a custom rom can help...
P.s. - if i ever meet a nokia official... i wud suggest them to stop making phones and concentrate on making battries and start exporing them to samsung or iphones lolz...

Very often after flashing a new a battery problem happen, it's necessary to calibrate the battery using appli like Battety Calibration.
That's a problem for a couple of users, unfortunately.
Specially JB rom ! I've tried several tips, like switch off wifi, sync, Google now, multi windows, battery calibration etc, without success.
Still waiting a decent rom in the future? (dreaming is permitted, right? )
Hi guys,
i recently sold my crappy Xperia Tipo (i goddamn hate it) and bought an S3 Mini, i love it, it's my first day with it, but i'm having serious issues with the battery life, it discharges too fast,
When i bought it i drained all the battery, then charged it (turned off) to 100%.... but still its draining too fast.
The phone is brand new... i don't know why it discharges so fast, it's on android 4.1.2:
Should i update to a custom rom? i would like to taste KitKat, that CM11...
Do you suggest it?

The battery is not our great ally here xD
But custom rom have bugs, no matter what ppl say.. they have and will have for a while...
IF you dont care about warranty and want to take the chance to improve your cell, yes, there are some good roms to upgrade Jelly Bean to KitKat or just update to 4.3
Personal, Maclaw have a great work done in his CM and Carbon (Don Like at all Slim or OAKP ) that work with kit kat, still in process; in the case of 4.3 dont know, i just did the jump from 4.1 to 4.4
I'm actually using Mac CM 11.0 and I have to charge it every night, the same as with a Stock ROM / based custom ROM. I'm actually doing around 5 to 6 hours calling and a little bit of Line/Whatsapp during the day.
It's faster, and I like Open Source ROMs the most, because of the design, but it's up to you.

hey guys,
the road so far:
I started rooting and installing TWRP recovery in my phone, then i updated to Maclaw Kitkat 4.4.2 and flashed gapps...
i noted that the phone improved just a little bit, because without the bloatware it's much better, i don't have any bugs actually...
From 5 am to 11.30 am it went down 3% without 3G, i went to sleep and lost 3 % that's a little bit better...
I suggest to do a full rom backup with TWRP and try a new custom rom, 4.4 or 4.3!!
leave this post open for if someone knows something else about the battery life.

Dont know much how long is battery life with the stock rom, bcause i started using the phone directly with the CM11 of maclaw. I am running the 20140120 version, and i am always reading about the news and comments of the last maclaw's release.. (think i will do an update soon..)
I see that battery life increase changing the governor ( abyssplug ) and the I/O scheduler ( sio ). I dont use wifi so much but often 3g data connection (chat, mail pushing, some internet surfing etc..) , listen music, make some photos... airplane mode during night!
after 1,5 day of use.. i should charge!
had an xperiaE before with a stock 4.1.2 jb and the battery life was greater... ( but is completely another device with another hw and os .. )

I'm kindda pissed of with the Xperia line, my friend had the Xperia U and smashed it across the hallway because after hours and hours of flashing new roms it always came down to poor...extreme poor performance haha.
What's the governor ?
governor takes control of which the CPU is used... there are a lot of threads about...or just google the word and you will find a lot of literature..
