Correct me if I'm wrong, here are some things I've been contemplating when flashing new kernels via the awesome app Kernel Manager.
I've found it useful to clear Battery Stats along with Cache and Dalvik Cache; I saw that Kernel Manager allows you to clear both Cache and Dalvik.
What are y'alls opinions on Battery Stats? Does it make sense to clear them out along with Cache and Dalvik when flashing a new kernel or is it just overkill?
Before I flash anything, I always wipe the cache & dalvik and yes, if I flash a kernel, I also wipe the battery stats. I want to make sure I get an accurate gauge of how my battery performs with the kernel I'm using.

When flashing a new ROM using ROM Manger, if you choose the wipe data option does this wipe the Dalvik cache too?
I have seen posts saying it doesn't, but when I watch the text that appears on the phone's screen during flashing it does seem to be wiping the Dalcik cache.
Does anyone know?
I was wondering if selecting the wipe data option is the same as doing a total wipe first like you can do if you flash manually from recovery.
No one know?
I have been doing some googling and found similar threads and I think that it does clear the Dalvik cache but I am not 100% sure.
Not as far as I know, but I have been wrong before. Just clear the cache manually before flashing.

flashed SRF 1.1.0 a couple days ago (first time rooting and all -- yeehaw!), so this is a n00b question
i know that for that, i had to data data, cache, and dalvik cache
i've also flashed the Vision kernel, which ... seemed like it didn't require wiping data or cache or dalvik cache
i've also flashed an impaled keyboard tweak and that one seemed to require wiping just cache and dalvik cache, but not data (as i recall)
so... i'm just confused, and wondering... when do i know if i need to wipe data, or just cache/dalvik, or none at all?
i just flashed the AOSP screen lock zip .. didn't see any instructions, so i figure wipe cache and dalvik, but not data (didn't want to lose my texts was my thinking)... and i just made that up. and that seemed to work. but i figure if i knew the rules of thumb, i'd feel better like i knew what i was doing
any clues / insights would be super appreciated!!
The only time u wipe:
1.
Data/Cache/Dalvik
For a rom flash that says on the rom thread wipe wipe wipe
2.
Cache/Dalvik
Is mainly when u flash themes its reccomended
3.
As for kernals and other mods unless it says to wipe then you dont need to...
Nice info so far.
After you have done this a while you can start drawing from your brain through osmosis and you will understand: if it doesn't work the way you want....EXPERIMENT.

the above post is correct, sorta.
anytime u flash something that mods /system its good practice to wipe cache and dalvik cache.
flashing a kernel, u will want to wipe cache/dalvik cache just to be safe. it prevents any sort of incompatibility between kernels.
my 2 cents
Ive since seen both sides of the fence on this one.. but are people still wiping caches ( dalvik etc ) when installing new kernels? Or is that one of those old practices?
Still doing a wipe of cache and dalvik cache when updating kernel. Its the best practice.
I would strongly suggest wiping cache and dalvik before flashing your new kernel, or anything else for that matter. I've been wiping, flashing, wiping again before rebooting, letting the phone sit idle for 10 minutes after first reboot,and then reboot again. Use as you would normally from there. Just how i do it. So far so good.

I agree...I have always wipes the caches when I flashed a new kernel and never had a problem...better safe than sorry

I couldn't post in the development thread but thought this post might be helpful to a lot of people.
Now I could possibly be wrong about this, but if I am correct; all ROMs that are up to date currently are all synced to the stock CM10 Gerrit picks. Now having KTweaker is a very nice function; (With UV and OC), but since it is technically "out of date" there might be some instability. Another case of matter, Undervolting and Overclocking can cause issues depending on the hardware of your phone. Settings that should be able to work with MOST phones are posted in the OP. (First page.) If after those values you are getting reboots, you can try to increase the values to see if that helps in any way. Otherwise, if they are happening too much I would recommend sticking to the stock CM10 kernel. Even though the kernel is flashed by stock when first flashing the ROM, if you would like to re-flash the stock kernel you can download it from Task & Ktoonesz ROM in the OP. Make sure to give thanks to them as they are very helpful and as opposed to dealing with questions on the regular hopefully this post helps answer some. Thanks for the great ROM by the way guys. -
On another note, I am using this kernel with AOKP and have yet to run into any issues thus far. I am not sure if you have tried this, but you can try the settings on the OP for good performance/battery life but not without clearing/wiping the phone properly. I understand some people hate full wiping but I find it to be necessary before reporting anything not functional. If you haven't done this and I quote from everyone who has said this and posts that recommend this process.
(I personally only recommend doing this after charging your phone to 100% to avoid draining issues.)
After download of latest ROMs/Kernels:
Reboot to recovery
-Wipe Data/Factory Reset
-Wipe Cache
-Wipe Dalvik Cache
-Wipe Battery Stats (Optional) (100% battery recommended.)
-Flash ROM
-Flash 7/26 Gapps package (Most stable as opposed to customized packages such as Inverted Gapps)
-Go to advanced settings once again.
-Reboot RECOVERY.
-Flash Kernel
-Wipe Cache & Dalvik ONLY, once more.
-Finally, Fix Permissions.
-Main menu and Reboot System.

Wiping battery stats is unnecessary on these phones because Samsung uses an automatic calibration.

Ah I see. That I was unaware of. Luckily I posted it as optional. I find my battery to last an extremely long time with heavy usage especially when listening to music and such. I have yet to encounter a problem so far. I also recommend to those who use it; to download flash player and use Titanium Backup to keep it easily accessible, since after flashing AOKP you lose the ability to download it from the app market by stock without changing the DPI. A lot easier for those who don't want to tinker with those settings.

Okay, I will install an update to my custom ROM in recovery, so I wiped cache and dalvik and installed the update. I just want to know if it will affect the battery stat/cache by wiping the cache and dalvik?

No it wont affect at all..
Jm!
Not sure, but I think it does affect the battery and wiping the Dalvik cache because when (sorry for my english) I apply it, my battery goes very fast and with time and use the term returns.

it won't affect a thing
The only way to affect battery stats is by doing a battery calibration, using the app or a recovery that supports it, or by flashing an update which replaces the actual "battery file", which I forgot the name...
