Hi guys. I've rooted couple of months ago and I am still looking for a good rom. ILWT 419 right now but it doesnt have gpu video playback support like some sense romes and have terrible wifi speeds for downloading...
But I wanted to ask something else. clockwork boot menu. There is "reset battery stats" or something among these words in advanced menu.
Is it wise do use that? Always when I am installing new rom I am using "Clear cache, wipe, clear dalvik" options. Don't know anything else about other options.
Right now I am getting 1 dat with moderate use.
Edit: Also one more question. I don't want to create new topic just for this.
What is a difference between superwipeg2+ext4.zp and clearing/wipe as I explained above?
The reset of battery stats is useful if you notify that your battery drains faster than usual...you have to fully charge it and then reset its stats from recovery.
The superwipe is a script that does all the wipe operations at once plus, in that case, formatting as ext4, that otherwise would be ext2. It gets better performance with some roms...anyway it's recommended in the rom's topic if it's the case.

Hey,
I have problem. I wiped the battery stats in Recovery mode like this one thread said to do, if experiencing battery problems. And since then, when I reboot my phone, it won't boot...only that white HTC screen displays. Nothing else happens. I always need to reflash my rom for my phone to boot into android. Any ideas???

Simply wiping Battery stats shouldn't do that. My concern is the fact that you say you have to always reflash your rom, are you saying that even now if you reboot it will not boot up your ROM? if so I would recomend doing a wipe of /cache and /dalvick-cache and seeing if that helps if not do a full wipe /system /data /cache and /dalvik-cache and reflash your rom but be warned doing that will lose all your data
This might sound obvious, but I am curious how wiping battery stats actually help recalibrating the battery? I do it once and the battery percentage drops to 0% immediate on boot, while there are still plenty of juice left.
What the correct way to properly recalibrate the battery?
Download current widget, charge your phone till current widget shows 0mA, then wipe battery stats.
What changes when you wipe your battery ststs? I've came across a thread for HD2, which said that wiping battery stats in recovery is equivalent to deleting /data/system/batterystats.bin (or something like that) and rebooting. Obviously being WM device the HD2 lacks a recovery. The thread also said that this should increase the maximum voltage the battery reaches while charging (to ~4220mV). With my DHD I reach 4199mV with or without wiping the stats. Also that thread suggested that the minimum voltage (equivalent to 0% battery) depends on the kernel used and could be as low as ~3200mV but all the ROMs and kernels I used can't reach those low voltages (usualy around 3500mV). Can anyone please share his experience with the battery voltages because I think this is the most objective way to measure the effect of wiping the battery statistics.
I wiped my batterystats with CWM in recovery mode and had no problems

Hi,
Try to download from market "Battery Calibration".
Install it and plug in your phone to charge it.
Wait untill battery is 100% charged.
Press calibrate battery on the screen.
A popup will show you the result and the App. automatically deletes the file "batterystat.bin".
Than plug off your phone.
Now you are joining a new battery life, more stable and performance than before.
If you also want to have your battery always under control, download currentwidgets and place it on home screen. It will show you how many ampere your battery is consuming.
I hope this post is usefully for you.
Bye
Is it possible to backup and restore your battery stats? I saw it was a feature on the galaxy s2's hyperdroid rom. It would make things a little easier (yeah i know its not that hard to just charge to 100% and let it drain) but it normally takes a day for that to happen and I can leave in the morning with 20% charge to get me through the day.
havent seen anything on backing this up yet but i much rather prefer to do a calibration after every rom or kernal flash as opposed to having a backup of the stats

I agree with Paul it's best to wipe the battery stats everytime you install a new Rom however if you did want to back them up then use something like Root Explorer and browse to /data/system and make a copy of batterystats.bin
Hey,
i'm using the MildWild CM-Roms for quite a long time now. At the end of the first post (http://forum.xda-developers.com/showthread.php?t=1453287) it says "wipe the battery stats".
I already heard about it, but everytime it sounds different. Is it just wiping battery stats in recovery and that's it? Or do I have to pay attention to something special, like having my battery fully charged when doing this, etc.?
Is it really important to do that? Somewhere I read that it's just important if you flashed a rom while the phone is charging - well, I flash roms via zip on sd and recovery, so the phone was never connected to the charger or to USB.

No. It is to be wiped only if you can't stand the sight of anything in your battery usage statistics. It gets wiped every time you charge it above 90% either way.
The wiping of it is the greatest android myth ever, even bigger than task killers. Furthermore it was disproved by Google's Dianne Hackborn.

Hi every one I've got a problem.
Am guessing I've bricked my phone but as the handset won't boot I don't see how I can restore using an RUU stock ROM (Not that I really want to do that.)
Okay so have a unlocked Wildfire with a nice 8GB SD card only with Clockwork mod 3.0.6 though - dam phone refuses to upgrade.
Well have been sampling different SENSE ROMS, Wildpuzzle fine! KoolSense fine!
(Well thats to say fine as in the ROMS installed and loaded correctly.)
Come to try REMPuzzle it says to partion the SD so I do this.
I install the zip.
I reboot.
Now the dame phone switches on, displays bright white with the green htc in the centre, and then just sits there.
No 'quietly perfect', no little jingle, no nothing.
I beseech the xda community, please help a noob. I need my phone back for Monday.
Doesnt sound like youve bricked it to me so thats the good news.
Are you using custom mtd sizes? Are you sure you partitioned?
Did you do system, data, caches wipes?
Are you giving it time to boot?
By the way if you can get into recovery then you are not bricked.

easiest way to fix is :
format your sd card from pc....use fat32
them copy cm7 or cm6 on to your sd card...get the latest radio image....
boot in recovery.....clear cache,dal cache,user data,battery stats....
install cyanogenmod or kwbr....reboot from recovery....your phone will be fixed...it should boot now properly....if your gps doesn't work...flash the latest radio image from recovery...
a small advice as you are a new user try not to use ex partions...it tends to screw up the boot if not done properly.....
try lite roms like cm7 for gb or cm6 for froyo
and for sense try kwbr rom....its the best sense rom with froyo...
good luck

Are you not going to advise of backing up sdcard to pc 1st before format?
Imho and ive read up on this many times..... Battery stats wipe is pointless as they are reset automatically on charge.

oops yeah forgot....
ok did some ....research...came up with dis:
"
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/ directory."
No, it does not.
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away."

Hmmmm......... haven't I or sly mentioned that in just about every single thread related to battery. People will just ignore it though and suggest wiping it as that is the only thing they can see with there eyes relating to the battery.

Hi , I'm using a custom rom (Revolution 9.3) and have a strange issue.
I normally turn my phone off on a night to put it on charge. When the phone is fully charged it now turns itself back on. Is this normal and is there a way to stop it doing it. I have not had this problem either with the official rom or with other phones i have had with custom roms installed.
The other issue is when i wake the phone in the morning it has the "people" app open.To get rid of this i have to press the home button which crashes Sence .Once Sence reloads all is fine all day .Apart from this im very impressed with the Rom so dont really want to change it.
These are minor issues and not the end of the world but i would like to know if there is a cure. I'm fairly experienced in flashing roms but have been unable to locate any reference to this on this site. I have had to post on here as i havent the 10 posts to allow me to put in the developers section for this ROM. Thanks
I think it's clockworkmod recovery that turns the phone on when nearly charged.

did u perform full wipe, erased cache and dalvik cache before flashing ROM

Yes did full wipe with super wipe as per instructions .Also did a cache wipe and dalvik cache wipe before and after install.
Thanks for the info about clockwork - it hasn't had this effect on previous phones plus when i flashed back to stock rom but still with clockwork recovery it doesn't turn on when it reaches full charge. Presuming it is clockwork is there a way to stop it ?
Open to any more suggestions though.
It's one of those things that is bugging the hell out of me but i can live with it for the extra functionality the rom gives me and the better battery life.
Little worried that the extra on time it is giving me will have a long term effect on battery life and also dont want the phone going off with text at two in the morning.
