To anyone getting battery drain issues with custom ROM like had. Would like to share a method that helped me get my battery stable. First wipe cache partition followed by wipe dalvic, then factory reset. Now go to mounts and storage and select system format after this step flash ROM and Gapps as usual. After this I wipe cache partition and dalvic one more time and reboot. I knw it seem like a lot to do but it has work for me I now get 10+ hrs of battery life. Just remember to use titanium backup or Go Backup app otherwise be ready to reinstall apps and layout settings all over again. Hope this help and if any questions Pm me an I will do what I can to help. :beer:

Yes I agree with you but sometimes during install battery goes hay wire and installing this way it seems to fix it. A few others and I have had this issue and this had fixed it. Issue with a few AOKP RELEASE. Thought I put it out there for those who have had this issue and don't format before install

but they have been told time and time again, if you dont fully wipe before flashing, then dont report anything....its simple.
you posted instructions on flashing a rom, the same as any ROM OP should.
BTW, wiping cache and dalvik is placebo. when you boot after changing system, the dalvik cache gets rebuilt....doesnt matter if you wipe it or not. what can matter is /data partition if you have rogue app or rogue settings that are incompatible with the version of the rom you are upgrading to.
this thread is just a common sense thread:
if you have problems fully wipe then flash again.....
even says so in the AOKP OP......
Totally agree but still you and I know that reading through AOKP page the question comes up and at least with this they will avoid asking the question on thread page. Please PM for further comments.

Hello,
First and foremost, I'm loving this rom. I'm a noob and getting my hands dirty figuring all this out.
Now with that said:
When I try to connect to my wifi network it keeps saying authentication error occurred. I have tried everything and the only thing that fixes it is restoring my backup to my stock rom.
Please help!!!!

I will say 90% of the people in here will say it is not the rom. just because theres seems to work. and i tend to agree. what have you tried to fix it? besides going back (to Stock). i have not had any issues with WiFi on Serephim yet, so i can not say what a fix would be. maybe wipe your cache's. when i had that issue on GB i had to reinstall the kernel and boom it worked. but seeing as though we do not have one yet for ICS. i would say wipe and worst case reinstall the from after a very Thurough Wiping Process.

Then if your into flashing right now, just try either the superwipe.
Or this is how i wipe.
I factory default/format usb from inside the rom.
I wipe factory/data from cwm
i wipe cache partition from cwm
i wipe delvik from cwm
then i flash "Rom" and reboot.
this leaves nothing from previous roms and or Gingerbreak roms.
try that and see if it works. if not then i am out of ideas until a kernel source is released.
Ok i will try that and see if it works...
Thank you!!!

I fixed it.... USER ERROR.. I Don't want to admit this but I was entering the wrong password and my old Rom had the password saved so I never had to enter it...

Now my head i about to explode
Anyhow, I have an annoying problem.
Before the upgrade to XXALF6 I noticed no problem other than the known drainage of the battery in idle mode.
I rooted and flashed a ROM and it was ok.
But I got sick of the ROM and I hard reset the phone.
No problems.
Then I upgraded to XXALF6 - still unrooted and all.
First thing I notice is that the phone is lagging a bit now and then. Then when I sent and recieved an SMS or two the phone hung and rebooted.
I seems that happend because when vibration was active.
Also there was a new message saying "com.google.process.gapps" stopped working. And that came up again and again.
As far as I could find online that had to do with syncing the calendar and it should help to clear calendar cache in the phone. It did not.
Then I rooted the phone, just "CF-Root-SGS3-v6.4", no other ROM.
Now the problem was even worse and also the sound stops working on and off all the time.
I tried to find the "com.google.process.gapps" with a file explorer with no luck.
I do find it in ROM Toolbox but its not possible to see the where on the phone the file is even there. Also its not possible to uninstall or even kill the process.
I did notice there seem to be doubles of some apps that I didnt notice previously to flashing CF-Root this time.
And I recall the new guide never mentions to wipe any phone data whatsoever during rooting the phone, and now I am thinking that maybe that should have been in the guide?
Anyhow.. appreciate ANY tips at all, Im so sick of this for the moment ^^
Go to cwm recovery, wipe cash, wipe dalvik cash, wipe data/factory reset, then go to mounts&storage, format system. Then put your phone into the download mode and flash ROM again with odin. This should give you a nice and clean install,without any force closes..

I did wipe all things, cache, Dalvik, battery and user data with CWM.
At the moment it seems the phone is quite okay actually! The only thing left is SU.
U think I have to format system as well? What else would really be "cleaned" out that wasn't allready with the wipes?
Trust me,some of the devs insisted on formating system before flashing their custom roms,and I did have a bunch of force closes,until I decided to go their way and fully format the phone. It then installs everything from the scratch,so there's no way anything to go wrong.. give it a try,and report back... btw. make sure that you DO NOT restore any of the system data,if you use TB

Yeah I pretty much learnt same way as predja it is always better to do full system wipe, it is not always necessary with some roms but if you do it you won't come across the problems you have as often.

Hi there first thread for me
I was just wondering, I am on stock Samsung ROM but am thinking of installing either Foxhound or Paranoid Android (possibly CM10 when stable supported version is out)
do I need to do a full wipe or can I just wipe cache partition, dalvik cache and fix permissions?
Also out of Foxhound and Paranoid, which would you guys recommend and why? or would you recommend I wait for CM10?
Thanks for all the help guys, this is a great community!
To each his own. Try both and decide yourself. Always recommended to do a full wipe.
Sent from my GT-I9300 using xda app-developers app
thanks very much for your help, I might just try both as you said and then I can make a decision from there
What actually happens if I didnt do a full wipe and just wiped the caches and fixed the permissions?
Full wipe is recommended but always not necessary. Try installing the Rom without a wipe and if you didn't get any fc then leave it as it is, else wipe it. Also fix permission is not required every time.

If you lucky (occasionally), nothing happens.
If you unlucky (most probably) , unpredictable bugs will annoy you to death

thanks guys for all the help I think I have just got to go for it and flash a new rom, just hope it works these things always seem to go wrong for me lol
I keep reading people suggesting wiping multiple times before flashing a different ROM. Could I get a few people to sound off on the subject? I don't see why you would need to but I am in no way an expert and am hoping to learn something from these responses. Thanks!
Better safe than sorry. Only takes a few seconds.

I've heard both sides of the issue. Some state that you should do it just to make sure to get everything cleaned out in case something was missed the first time. I've also heard that you shouldn't do it, as it puts unnecessary formats on your memory and isn't really needed. I don't wipe multiple times and I don't run into issues.

I don't multiple wipe. But I do wipe multiple areas - system, cache and dalvik every time. Works fine for me.
I was wondering how it could possibly help but I don't know everything for sure

"Full" wipes help with FC and random reboot issues between ROMs. They're not always required, but they do help to ensure "clean" installs and minimal issues when switching ROMs.

multiple wipes was only necessary for older cwm recovery. *it had a bug and wouldnt wipe properly*
newer cwm and twrp2 you have no need to wipe more then once but if it makes you feel better then go ahead

It probably also comes from people having little idea to what is going on.

I found this to make a big difference. When flashing a new rom, make sure you wipe the system before flashing (never used to do this, now I'm finding my fresh installs less buggy). If doing a dirty flash, wipe cache, Dalvik and fix Permissions after.

OK, that's about what I was thinking. I always wipe system, cache, dalvic, and usually do a factory reset. Thanks for the help everyone
Sent from my SAMSUNG-SGH-I717 using xda app-developers app
If you do a factory reset... That wipes the dalvik cache, as that resides on the data partition. That also wipes the cache partition as well.
And any dev worth flashing a Rom from should have it format /system in the script.
All i have done for ages is factory reset and flash.
Hi,
My s2 has recently started to have very poor battery life. I am on stock JB firmware. I've never rooted this phone, and don't plan to until the phone is out of warranty, which is still about 6 months away.
The phone was pretty full of apps, so I decided to do a factory reset: settings> backup and reset> factory data reset> format USB storage ticked.
This fixed a problem that I was also having with my WiFi connection being slow, but it doesn't seem to have fixed the battery life problem. The phone does not last the day, even with very little use whereas before it could go at least 2 days before the battery went flat.
Is it possible that something has not been wiped during the process and is still causing a problem? Does the 'format USB storage' option wipe the internal SD card?
In the battery menu the biggest drain in 'android OS' with around 50%. This suggests to me there is still something wrong.
Any help would be greatly appreciated.
Thanks.
Maybe you need new battery..
Check the apps which gives regular wakelocks..
Download wakelock detector and see who is the culprit

maybe you need to wipe dalvik cache and recalibrate battery maybe some times it's a bit a galaxy s2 bug
http://forum.xda-developers.com/showthread.php?p=18600161
Thanks for the replies,
I don't think its the battery that is the problem, as I would expect a more gradual failure than what I have experienced.
I'll try the wakelock detector, that sounds like a useful tool.
Battery cal and dalvik cache wipe may also help. Is there a way of wiping the dalvik cache without CWM recovery? As I said in the first post, I dont want to root the phone
I think stock android recovery has a option to wipe cache...
Stock android recovery does have a cache wipe option. Does this wipe the dalvik cache too?

So u have good battery life on ics??
Thanks for all your replies on this matter guys. I finally sorted the problem. It was the USB charging port. It was dirty. I cleaned it out with some contact cleaner and battery life is all back to normal. Unfortunately my Wi-Fi problem is back, so I'm starting a new thread about that if any of you knowledgeable guys fancy helping me out!
