I read somewhere in the forums that after installing a new kernel u should do a battery data reset but now I can't find it can someone please post the insructions on how to do this. I know its under clockwork mod but I don't know if u have to wipe it after charge or before. Thanks

It is in Clockwork Mod. You have to boot your phone into recovery with 3 finger salute (camera, volume down, and power buttons simultaneously. Then in advanced there is a wipe battery stats option. Do this with a fully charged battery.
BONSAI 4 and loving it!
K thanks. Do I drain it now then fully charge it? Should it be on or of during recharge?

Fully charge your phone with it off, then wipe battery stats in CWM

Any help on the best/correct way to flash a new kernel ?
Sent from my PC36100 using XDA Premium App
Before I flash ANY kernel, I always go into recovery and wipe cache, dalvik cache and battery stats. Afterwards, I flash the kernel and reboot.

Same as doug. Battery stats is optional. If you look around you'll see that some versions of clockwork don't wipe properly. I'd suggest using Amon-Ra instead and just like flashing a ROM wipe 2 or more times just to be sure you get a clean wipe.
Ty both. I was just flashing and battery life was the worst. I'll try if now.

You'll see that people generally agree the first day or two battery life will not be so good with a new kernel.

I make sure my battery is 100% first too before wiping battery stats, then give it at least a few days of charging and draining to better judge what the actual battery life is like.

Everytime I reboot my phone my battery drops a significant amount. I tried charging it in full, unplugging it, & doing it again & then wipe battery stats but its still the same. Anything else I could do?

There are different theories/methods for this. I charge to full, unplug, wipe battery stats, plug in and charge to full again, wipe stats then let it run down to about 15% and recharge and wipe one last time. People will say my way is crap but it seems to help. Also, just letting the battery run down and charging back up seem to condition the battery to your new setup. There are several little tweaks made by devs in pursuit of better battery life so it may read inaccurately at first. Let your battery settle in. I say in a day or two, you will see improvement

Dunno about the "best way", but this is a convenient way without having to boot into CWM.

You can wipe battery stats from a file, I just don't remember what it is. My question is if I want to switch to a new rom, can I backup and restore it and not have to calibrate my battery?

From my understanding, what youre saying is that you have a current rom now. And if you back that up, flash to a new rom, and then go back to the rom you backed up do you still have to calibrate?
I believe your battery stats are saved when you back up, so I doubt you do, but for best results calibrate it .. especially because your phone dies different every day because you use it differently, so once a month, even with the same rom wouldnt hurt to calibrate.
There is an app called "Battery Calibration" by Ne'Ma that does exactly that. Its free. You have phone plugged in charging and when phone gets to 100%, you press it and it wipes the stats from the file

Wipe battery stats from clockwork then recharge to max then turn on phone
Sent from my SPH-D700 using XDA Premium App
No, lets say I'm already calibrated. If you switch to a new rom, the stats are wiped, right? If that's so, couldn't "/data/system/batterystats.bin" be backup up before flashing a new rom, and restored after flashing it so you don't have to re calibrate the battery?
I am new to the custom rom thing but I am loving it because I was about to throw this phone away "Xperia S" but after playing around with roms and kernels I am back to liking my phone again. My question is related to the battery, I added the PAC rom V18 and I also added the Nova kernel V5 but my only complaint is the battery is drained very fast that it doesn't go through the day, I am an average user so I don't listen to music or watch movies. Is there a solution or a kernel that can improve the battery life.
Thanks

Follow these steps:
1. Use your battery to 0%
2. Charge it to 100%
3. Go to CWM > Advance
4. Wipe Battery Stats.
5. Fix Permissions (This may take sometimes).
6. Again use your battery to 0%
7. Again charge it to 100%
I looked for wipe battery data in the advanced tab in CWM recovery but I didn't find it

Hi, this is a probably already answered. I am new with root and flashing rom. After i rooted my galaxy note 2 N7105 and using jedi x16 rom. Start to drain my battery fast. I already read many post about cpu governor and tweaks. I tried different governor but it has no help. Still my battery drain fast. Any suggestion why i encounter this battery drain? Sorry for my bad english.
Thanks!

My advice, better stay close to ROMS close to stock. Plus, turn off sync, google back up, motion if you don't use/need any of those features. And explore the settings, there are things that you can turn on/off to save your battery.
Thanks!another question. Is it true that i need to wait a couple of days to so that my noye 2 can adjust to the new rom? Because. I rooted and flash jedi x16 last thursday only.

Since it is recommended by the devs, yes.
Also try charging your phone til 100% then wait for a half an hour at least then unplug it, then go to recovery mode(CWM recovery) and under advance, wipe battery stats.
And you can try DisableService app from playstore, it can disable unnecessary services of any app. Less services running, less battery drain. Be careful though with what services you disable. Here's the link for the app https://play.google.com/store/apps/details?id=cn.wq.disableservice
Okay i will try that. Thanks! By the way i have 2 diffent battery. Do i need to charge 100% and go to recovey mode? I think this is a noob question. XD
Thanks for your reply sir.

Yes charge it until 100% and wait for it to charge a little more, at least half an hour. Cause sometimes 100% isn't really 100%, that's why this procedure is needed for the phone to know what's really a 100% charge. It's like a calibration. I think you can do it only on one battery since every battery is not exactly the same.

Are you using a white theme on your rom? Better change it to black or stock theme. White colors makes the pixel on your screen light up and drain battery.

Install battery calibration by nema from the play store. It will do the same job.
Sent from my GT-N7100
No offense but you know, I used to do all this battery stat wipe stuff. Calib...etc. Then I started seeing articles about battery crash and low burn in. On top of that I read increasingly more about how chain fire himself said wiping battery stats is placebo if you think it is healthy or has any positive effect ...I really wanted not to believe it. Lol but hey that was couple years or so ago. I Dont mess with the stats unless I'm testing my work.
