Battery calibration is not needed because when you flash a rom (stock or custom) it will always wipe your cache and this will give you the correct battery indication ( % )

If we ODIN to stock before flashing to a new ROM, is it still necessary to wipe battery stats?
i bought my new lg optimus one today i dont want try any custom rom right now just want to try any custom kernel for overclocking so can i flash kenel like franco kernel on my stock rom v2.2.2 v10d???
is it safe??
Yes man Go ahead, franco's kernal is the best.. no issues, as always do a nand backup in case anything goes wrong
one of the best kernel ,have u installed custom recovery ..
then flash the franco kernel v17-cfs version meant for froyo roms.

i am using rom manager there is option of wipe dalvic cache how to wipe battery status
Yes there would be an option once you start to install the kernel
After flashing recovery with rommanger,You have to boot into recovery, There are options in the list for wiping cache and battery status.

thanks guys flashed successfully first kernel on my phone now where can i find oveclock settings???
Wipe cache & dalvik cache from custom recovery and then flash kernel. That's all.
For battery stats:
- charge your phone
- when it's fully charged keep the charger plugged and boot into recovery
- with the charger still plugged wipe battery stats and reboot
- pull out your charger only after the system boots completly
To overclock install SetCPU (find it on the forum)

Charge your cell to 100% then clear battery stats ,that will give you more power i think ,or try battery calibrator ,it also does the same thing.

I tried wiping battery status before and after ROM install..never had any issues with that.
Battery stats have no influence whatsoever on phone crashes

Just wipe the battery when 100%
its just a standard thing.. If you don't believe us.
Don't blame the dev and us for making your battery died faster.

no frils crashes my phone if i go above 800 so i have set to 729mhz with set cpu & its stable now
I "upgraded" to the Italian version of ICS, as I couldn't wait for the real thing. Mistake - terrible battery drain has made it unusable.
So now I want to go back to Honeycomb. After half a day's effort, I managed to root my Tab, and have installed CWM. I have a copy of the UK firmware v3.2, but how to install it? Where do I put the copy of the ROM - on root of the folder structure I suppose? What do I have to wipe first before flashing with CWM? I say this because trying to install HC from Odin did not work and led to a reboot loop.
Of course, some kind soul here may be able to recommend a functioning ICS ROM instead ...
Otherwise, how do I get back to stock Honeycomb?
TIA

Go download the latest ics 4.0.4 rom from South Africa on sammobile.com.The latest ROM has better battery
Sent from my GT-P7500 using xda app-developers app
thanks - but how should I load? Do I need to wipe the tab first? If so, what needs to be wiped - cached and dalvik? I want to make sure there is no trace left of the Italian ICS.
thanks again,

Having tried that, the battery drain is no better at all.
Anyone with other ideas would be heard with appreciation,

All stock roms from sumsung, based on Android 4.0.4 suffer from battery drain ! So flash stock Android 3.2 rom via odin OR install this custom Rom: http://forum.xda-developers.com/showthread.php?t=1813651
- Android 4.0.4 (modified in the best way ! )
- battery drains 3% per 18 hours - the best battery drain since last year
- completely everything works as in stock samsung rom
- pretty fast (faster than stock Samsung rom based on android 4.0.4)
- flash A1 kernel v1.7 via CWM 5.5.0.5 mode ! (or battery will drain up to 10%) from here http://forum.xda-developers.com/showthread.php?t=1833136
Install:
1. Boot the tab and copy downloaded archives to internal memory:
* A1-p4-1.7-3G and JellyBeanRomICS v7 XWLP5 GT-P7500
2. Reboot in CWM
3. Wipe data / Wipe cash
4. Advanced - Wipe Dalvic Cash
5. Go back - Mounts and storages - format System, Preloads, Data, Cash (ALL data will be lost !)
6. Go back - install zip - choose zip one by one, flash rom first then A1 kernel
and only after then reboot.
Enjoy

thanks for the recommendation of ROM - I'm going to try it now!
One question: does it have to be CWM 5.5.0.5 - mine loaded is 5.8.3.1?
Update: I used my CWM and everything seems to be on OK: thanks for the suggestion and the instructions - really appreciated from someone who doesn't know an awful lot about these things. I'm going to have fun testing this ROM over the next few days and, if it has stopped the battery drain, that means one fewer gadget for the cellar!

I flashed Xgamer rom V1.8 and patch and flash doomlordV22 kernel with wifi modules and flash Baseband 64 I see my battery drops 1percent per 10 to 20 sec is that normal? even i no apps is on background before I flash this rom my battery can last 2- 2.5days but now my battery can last 1 day I reflash the rom with full format and clear davik and I underclock my phone but the same status ~_~ what should I do I like this rom so bad it is fast and my temple run has no lag on stock my temple run lag like hell!!
Check if the ROM supports the kernel. If it does, then flash the kernel first with Flashtool. Then boot into recovery, wipe data, cache, dalvik cache and then reinstall the ROM. Let me know if it works!

Hello,
I was update my i9100 to CM 13.0. Everything works fine, mobile is fast and in idle is battery good. It should be better, but no problem... But. If I am working on phone, battery is draining very fast. Some about 10% per hour. I try reinstall, wipe ally etc. Still bad battery life.
My kernel version is: Linux version 3.0.101-CM-g3419d27.
How I was installing CM13 from CM12
- flash cwm via odin
- install kitkat compatible cwm from zip
- wipe data / factory reset, wipe cache and dalvik cache
- flash dorimanX kernel + 3GB pit file
- install CM13.0 + Gapps Pico 6.0
What can I do? Battery life is really bad.
Thanks and sorry for my english.

Hi,
If you find that screen on time is bad on CM13, you might want to consider downgrading. You could try running greenify to hibernate unused apps, but it may not help much. Other than that, nothing else can be done to give a noticeable increase in battery life.

Also if you have just installed CM13 give it a week or two as I found the first week the battery life seem a little crap but balanced out the following week
