Not true.....on phones like the S2 that have a 'fuel gauge' that may be the case.....but wiping battery stats still works on the W.
The only thing that's been removed from CWM because of its (what they called placebo effect) was 'fix permissions'.

I provide links to 2 versions of CWM. You could re install the older version (via terminal emulator as detailed) it includes the wipe battery stats option. As far as I can tell, there's no REAL advantage to be gained from running the latest version of CWM other than the fact that it occupies a slightly smaller memory footprint (due mainly to the decreased functionality).

The SGW has a full gauge too but this whiping stats and battery calibration nonsense floating around is a myth.
The ROM is collecting battery stats while it´s running and whiping them on each reboot. So going into recovery and whiping them is the same like just rebooting the device. Just by doing so you are whiping them twice before the phone gets booted again.
Wrong stats do have other reasons than not a well calibrated battery. Like for example a bloated battery that is already dieing or some background processes draining the battery.
The stats are just what you get displayed in your ROM when looking at the battery consumption statistics. They have no influence to how long a battery lasts, even if they are incorrect.
Ok I need to correct my statement above a bit. Depending on which ROM you are using the stats are not whiped on each reboot but on each full (or partial) charge. But also when the phone gets turned completely off and on again. However the rest remains the same. So you can whipe them by going into recovery or by simply charging it and then by removing the charger from the plug.
The results will be te same but they will not fix the root of the problem.

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

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

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?
Guys, I don´t know what happened but 2 or 3 days ago I started noticing that every once in a while my battery starts draining super fast. I mean 10% in 20min. I went to bed yesterday with 67% and when I woke up I had zero battery. I notice that when this is happening the phone gets really hot. I didn´t change anything on the phone but I did get some updates these days (1 small system update, facebook, smooth calendar, facebook, whatsapp.....at least I think these were the ones). Any ideas what might be happening? It´s random thing. Yesterday it was good all day long and then at night it happened.
I´ve just tried doing a factory reset but nothing happened.

Sometimes an app prevents your phone from going yo deep sleep. Install betterbatterystats. It shows which apps are causing wakeblocks. Uninstall all apps. Also, which rom and kernel u use?

When I go to power and then usage, the biggest consumers there are "Android System" (54%) and "HTC Sense" (24%). I´ve downloaded Gsam Battery Monitor and it tells me sreen 50% and app usage 46%. When I click in app usage it tells me Android System 20% and Kernel 9,6%.
I have no idea if these numbers are excessive or not.
I did a factory reset and I´m not charging the phone to check out how long it takes to go down from 100%.

You can only do this with an unlocked bootloader and have flashed a custom recovery.

So you think that when you are at 100% of your battery, you suddenly get access to the recovery?... (this is what you literally say)
Or did you mean to say that your battery stats are wiped when the battery is at 100% .
Still I think that the second explanation is one big whoop, since my battery used to drain life too with a dubious combination of kernel, recovery and ROM. A fully charging of the battery (which I do every night) did not make this problem go away.

In fact wiping the batt stats will not make your phone last longer on a full charge, it resolve the problem that the rom will not display wrong batt info
That's what i learned

Factory reset resolved it

Pretty much lol. I mean theres no harm in it but its a waste of time because lithium ion/polymer batteries don't have a memory effect.
So pretty much after you flash a new rom, just use it as per normal. I've tried a lot of different scenarios over the past 3 or so years with battery calibration and roms and never noticed anything significant. Mostly placebo
Edit: with that said, if you feel more comfortable doing a calibration and you feel your battery is better. Just keep calibrating
For example: when I flash a rom, I still wipe dalvik cache out of habit even though devs have already said it gets wiped when you do a full wipe lol

Re: [Q] [HELP] calibrate battery stats
It is definitely normal, no need to wipe stats. When a battery is full (when it is ON) it will reach 100% (but not so sure since my battery health isn't that good) but if you charge it when it is OFF and you turn it on you will get it at 99%, Always.
Also, no need to wipe battery stats. It is useless. Battery Stats will wipe itself after full-charge.
Calibrate? Don't think so..

Check if the battery decreasing or not in other apps / just go to setting > battery. If it's decreasing in there that means something has missing in your system UI.
For the easy fix just install some new theme and you will be good to go

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

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.
