I really wanted to know how well does 2.2.1 stock firmware such as JS5/JS3 performs nowadays.I read alot posts saying that lag fix is no longer needed in 2.2.1..how well is the battery life without applying the lagfix and kernels? and the performance? Is that really ok we don't apply lagfix or any other kernels on 2.2.1 anymore? so for those who never apply lagfix or kernels on 2.2.1..would you mind sharing how well does your sgs perform? in terms of battery life and performance? Is the sgs on stock 2.2.1 performs not much difference from a lagfixed sgs?
Completely stock 2.2.1 JPY on XEU. No lag at all I can notice except for the Market which for some reason seems to hang for a few seconds but I presume that is the app as it doesn't happen anywhere else. Battery last 1-1 1/2 days on full charge light to medium use.
Stock JS5, flashed with Odin, lost all settings in this progress, but it works perfect since 4 days. Battery life and overall performance improved over JPY.
Personally I see no need to switch to a mod/non-stock firmware. Also, I only needed root once, when the gSensor calibration data got stuck and I needed to delete a special file.
2.2.1 JPY - JS5
On 2.2 (stock) it was a touch laggy, so I used OCLF.
On 2.2.1 its actually faster with OCLF disabled and uninstalled, particularly so on boot....
This also means no worries when the OTA 2.3 update is available in some 8 weeks, no possibility of losing everything in a crashed filesystem incompatibility problem.
YMMV

OCLF is DATED man. Never even touch it with a barge pole. For those looking for STOCK PDAs to use, check my signature.
PS : I personally feel Modded ROMs are overstuffed & way too bloated. But that's ME.
PS2 : Many people use Modded ROMs for their ability to change the top bar with battery mod & some such things, I use ADWLauncher & with a flick of my finger, the top bar disappears.
Use BattStatt for percent charge remaining & charging mode display, you have hundreds of apps & widgets to help you out.
I feel that you don't need custom rom or kernel's if you are satisfied how it works and looks.
But if you want more speed and less battery drain you need a custom kernel.
Also if you want to change the look you also need to use a custom rom.
People that's say you don't need lagfix has never use them or can't see the different.
With the latest stock firmware the gap between them has shrink, but it still different.

I use stock 2.2.1 JPY and it's fast enough for me, no noticeable lag, basically if the phone was released with the current ROM the term lag-fix wouldn't have existed. I use LauncherPro with other battery apps which provide enough customisations for my needs.
I previously used voodoo on 2.2
My observation, made me believe that there is no need to have any lagfix with 2.2.1, everything loads fine and smooth, a big change. No problem with market even. Only lag, I experienced was because of app but not OS problem.
Battery life: with light use, I get 2 days complete and with medium use, I get 1 & 1/2 day with full (I don't how to define it but I did a lot with phone for example played game for 2 hrs.) use its last at least 12-16 hrs. I did many tests so I am sure. Not bad though.
If you like how it works then there is no reason to change that.
Its big different from 2.1 when I did get the phone. You needed a lagfix then.
But now the phone is good without it.
But you still get alot more out of the phone when you start with custom stuff.
You cant ignore that and when you have crossed that line you never want a stock phone anymore.
But I have full respect if you don't want to custom the phone..

Used lagfix with 2.1. Didn't bother with lagfix under 2.2 and it was horrible. With 2.2.1 though, it's faster than with the old lagfix. Running stock 2.2.1 now.
As has been said, lag fixes wouldn't have been invented for Galaxy S if everything worked as quickly as it does under 2.2.1. They finally got it right.

I've been using 2.2.1 for ages, am on JS5 now. Recently I install Supercurio's Stock + Voodoo kernel that just gives the EXT4 lag fix without everything else. The phone IS quicker with EXT4, though battery use seems a bit heavier, I'll need a few more days to confirm that. Overall I was happy with stock 2.2.1 and only installed the mod kernel out of curiosity to see what EXT4 file system would do to the phone. I'm in two minds whether to keep it or remove the EXT4 and flash back to the stock kernel. I'd say it's up to you, if you are happy with your phone then keep it stock but if you are at all curious, try out a modded kernel to see, you can always go back to stock if you don't like it!
hmmm..so it seems performance did really improved alot since 2.1...do u guys thinks its ok if applying speedmod by enabling all the tweaks but without changing to EXT4 will have a batter battery life as EXT4 is well known for its battery drainage. As I know speedmod has lots of tweak including battery life tweaks.but the thing is it has sharpness fix and 500hz.i believe it sure use much more battery juice than the stock 2.2.1, well maybe a little? lol..so how do u guys think about this? [stock2.2.1+speedmod tweaks,without lagfix vs stock2.2.1(purely stock)]..lets take stock's battery as a margin bcos i think stock will have the best battery life isnt it since no mods at all.
I feel lagfix (ext4) is still noticeably faster than stock rfs. You notice it much more if you disable all windows animations (i.e. without window animations masking the real speed)
My phone is on JPY 2.2.1 with no mods at all, although I had lag on 2.1 there is no appreciable lag on my present standard set-up.
I normally charge my phone overnight, every night, but when I forget, which I do at least once a week, I end up with 42% battery at 08:00 on the second day, after 24 Hrs, which lasts me until the evening, say 18:00 when I recharge.
The only exception to that battery life, is if I am in a poor signal area for 2g, when I sometimes have problems getting 16hrs out of a charge.
mine is stock 2.2.1 jpy with a few system apps removed and a few custom system apps (ie customized framework.. with icon changed i did myself) and a customized version of twlauncher with transparency and landscape enabled.. also modified wifi with adhoc enabled..
i was not using lagfix but my other i9000m phone before it died/flakey again needed lagfix so tried it for awhile.. (this one is i9000t)
now using speedmod kernel and tried the ext4 lagfix and it is very stable and slightly faster.. same benchmarks about 14 linpack and 1340 or so quadrant. but things are slightly smoother and certain things such as bring up the entire app list or gallery is definately faster (bsically io bounded things)
been using it for over a month with no adverse issues.
flash JPY with odin....very smooth with quadrant 1100 no lag fix needed. battery life almost 2 days with moderate usage. No problem at all until now!
does lag fix improve gaming performance? no?
I love to play around with new ROMs and kernels and usually don't mind a few hiccups and occasional poor performance. But soon I will have a one week period where I need my phone to be as solid as possible. What's the best ROM/kernel for this?
I currently use CM7 as my daily and have tested CM9. CM7 is great except battery life is pretty bad, with both the CM7 and Samurai kernels. I lose about 1% of battery for every 90 secs I'm actively doing something - even on Wifi and with a strong 3g signal. A 15minute drive with GPS (and screen off) easily takes 10% off my battery. This is unacceptable for my upcoming event.
I would like a ROM/kernel combo that can go for a minimum of 12 hours with moderate use. No voice, but frequent texting, email, twitter checks, some photos, and calling up pdfs. Battery life and stability are the top concerns, but GPS is important as well. CM7 gives me the best GPS results I've ever had with my Epic, but like I said, the battery performance is awful.
Any ideas? Focusing on all the cutting edge stuff means I've lost touch with the latest improvements on the more basic, but more solid ROMs.
Thanks!
get a larger battery or pick up a spare oe battery as a backup.
this is one of those questions you just dont ask cause it all depends on how you use your phone and all that i know you say what you mostly use it for but it still doesnt help if you are looking for a stable rom as far as mtd goes they are all good and as far as kernels go they are all good but the kicker is just finding what works best for you feel free to play around with them flash one per day and figure out which one works best for you cause honestly we cant tell you cause what would extend our battery life might not work for you because you use your phone differently than we do but trust me all of our devs are gonna throw out something that doesnt work all the warnings are there and all the help and how to's for each rom and kernel are in their respective threads sorry i couldnt give you a better answer bud
happy flashing
Oh and I forgot to mention since you have been running cm7 make sure you don't flash a bml rom not sure if u were aware of that or not so only flash and MTD rom and kernel
CleanGB. No OC/UV, and buy an epic touch 1800mah battery. For me I get best responsiveness vs battery life if I run 100/800mhz with governer set to performance. You'd have to REALLY try to kill that battery in a day with this setup.
Edit: you use gps in the car without plugging it in? No wonder your battery commits suicide lol. If I use gps and stream music through bluetooth it still discharges on the charger.
There is no such thing. Even pure stock has errors on some people's phones. You need to try one or if it is that important than stock is your best bet. EVERY Phone is different. Read through some of the ROMs...95% of the people have no problems and 5% do. It is the nature of the beast. No one can tell which is best for YOUR phone. And if CM7 is giving you terrible battery life, there already is something wrong with your phone setup. You probably need to start from scratch and restore no apps or data and download apps fresh from the market.
I've always had good luck with CleanGB roms & kernals by toadlife.

But not everybody does. There is no best. I can easily say marcusantrom with shadow kernel is best on touchwiz and CM7 with the kernel it comes with is the best in general. I won't say this because different people have different phones and preferences... if you really want the best rom/kernel/theme, make it yourself.
In Soviet Epic forum, clockworkmod root you!
Hey guys,
I think I read somewhere that threads like this are not really wanted here? So I'd like to clarify first, I'm looking for certain aspects and not for "the best" rom or whatever. If there's more than one which would meet my criteria, feel free to just name all without any opinion to it
There are just so many roms and kernels and I'm having trouble finding information what they can and cant do...Sometimes it's just a download link and thats it!
I will be travelling with my Nexus 10 and would like to use an internet dongle via USB OTG to access mobile internet in the various countries and I would like to use OTG for storage (usb sticks i guess).
Also it should be stable/fast and I would like to somehow prolong battery life (UC/UV? Dont know anything about that yet but I guess that would be how?), just in case I won't be near a power outlet for a couple of days.
I don't really care too much about design, so minimalistic is best!
Which kernels can I use? Does the rom even matter? are there certain roms that seem to work best with the kernel I would need?
Thanks for any help!! I will get the tablet the day after tomorrow so it'd be awesome to have some information so that I can root and start trying stuff out immediately=)
If you seek stability then go for CleanRom and aosp+ kernel. As for battery life there isn't anything magic out there, just turn the WiFi off when you can.
UV doesn't help, no matter what you will be told, it's just placebo.
I've used mrRobinsons AOKP PUB ROM + Ktmanta kernel for the last 2 months. Just took it on a long trip, used a 32gb USB OTG just fine. I watched several movies and had great battery life. Performance is awesome too.
No experience with an internet dongle, sorry. I just use the hotspot function from my phone.

It bothers me when someone says that such and such is the only stable combination, it obviously isnt or no one would ever run anything else. I have never had problems when I ran AOKP, or when I used to run CM10, or running on Rasbean which is based on AOSP. Each kernel can have certain releases that have issues, just as Craig's AOSP+ kernel could at some point, but not every release has always or will always be unstable. To my knowledge only Franco's R12 has issues right now and all other kernel releases are fine. Franco's R11 is perfectly fine too.
Also I can both mathematically prove undervolting can save battery and can show you plenty of people with actual experience on it saving battery. So you should really stop going around and spouting off "facts" which are completely untrue. But you are right about there being no magic stuff, it is all science.
I get wonderful battery life daily using KTManta and a tweak of the CPU/GPU. But then, my tweak stops doing so well if I use a CPU intensive app like FL Studio. I can go about 12 hours or more and still have 30-40% of battery left, with off-and-on usage all day including some gaming. Extended gaming (I'm talking Asphalt 7, Shadowgun, not Plague Inc) will murder that, but that's what I set up my CPU/GPU to offset.
Also completely stable with RootBox ROM (or CM10, or AOKP, etc) so long as I don't try "hotplugging"
I have tested many kernels with stock rom KOT49H such as: franco, matr1x, hellcores, helldoctors, bricked but dt2w feature sometimes doesn't work when I put my nexus 4 in pocket for a long time (I must press volume or power button to make it works again). An other case lockscreen becomes unreponsive when receiving an incoming call (or put in pocket for a long time), I can't do anything except turn off my phone!
My battery is not good as I expect. It drain 1.5% per hour in idle mode (turn off all connection).
Can someone tell me about the best kernel for my problems? Thank you!

Dt2w is buggy(as always have been) so you have to wait for the fix.For now I personally recommend stock kernel.If you tried those kernel you should give stock a shot.
Try out touch control. Has dt2w, and is much stabler IMO
I tested the touch control with franco and stock kernel modify but the same problem^^
Then maybe switch to s2w?
I have tried most of the kernels that you mentioned and s2w works great with or without touch control.

I'd suggest that you use the Semaphore kernel. I switched to it for the very same reason, and ever since, I haven't had a single issue with its DT2W feature. And in the unlikely event that you run into one, the developer has added a fail-safe trigger to reset the touchscreen (tap on the screen with more than 3 fingers). In addition to the above, the kernel's pretty much well-rounded with features. And the developer is a well-spoken bloke too.
Try semaphore you won't be sorry.

I'm using matr1x kernel and having the same issue, seems that you saved me a lot of time, I was about to try a lot of kernels to see if I can get a better dt2w implementation. I think I'm gonna skip to Semaphore and see what happens.

Also Hell core kernel has excellent dt2w and now it's the only supported (no more s2w).

No issues at all? The OP said he tried hellscore and was the same as matr1x when it comes to dt2w.

This post is like 7 months old.
Since then there must have been over 15 newer versions for each kernel.
So, no comparison between what was happening then with current situation.

I can say that, at least on matr1x kernel, I have the same issue with the current version.
If I'm not mistaken, both the newer (after b47) HellsCore and Matr1x both use stratosk's dt2w. I've been using on HellsCore, and it works great. Much better than the earlier implementation of dt2w, which would turn the phone on inside my pocket constantly. stratosk's dt2w though is very specific to the center of the screen, and works great.
HellsCore is renowned for great battery life. But it's up to you to test for yourself, and to try different settings to see what works best for you, considering how you use your phone.

This is what I use with Matr1x, problem is not phone waking in my pocket, is that sometimes, it doesn't wake at wall using dt2w, I have to use power button, then it start working again.
But I'm gonna try for some more days, then I decide what to do.
Hellscore b47 or the newest version: b57 :3 don't use this 3rd party apps cuz it will drain ur battery very fast. 3rd party apps use module instead of tweak, so it's so bad
i would sugest this one.

I got my nexus 6p and it was pretty fast with no mods or custom roms, just had a weak battery. I ordered the battery on ebay (aftermarket THQL 3600mah) Now the battery is fine but ive heared theres no thermal contact or something like that. After installing a new kernel, the phone was sluggish... Installed root and Kernel Auditor and saw my for BIG cores were offline... This was NOT a problem earlier! Turning off Thermal VDD fixes this and turns the BIG ores on (Phew)! But am i missing something? I heard somewhere the Big cores were shut off to save battery or something. Any help and info would be awesome!
Kernels probably turning big cores off until there is demand. I've seen it happen many of times nothing to worry about. I have also battery from eBay works great just no temp sensor. Kernels are fine and all but sometimes can sacrifice performance. If you need your fix I found just changing the governor's on the stock kernel with elemantal app is all you need. Google search the article Flar posted about kernels. It really puts things into perspective. I'm no expert on the subject just from my personal experience.
