Hi can anybody help on calibirating battery on miracle v4 rom
no....nothing can be done

Do bump charging instead of battery calibration. Search it on google.
-Charge your phone to 100%
-Use this battery Calibration app:
https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=de
This app needs root
-Then let your phone discharge until it turns off itself
Notice: in this time you're not allowed to plug the phone to the pc or to the charger again until it turns off
-after it turns off plug the phone to the charger and let it charge without breaks to 100%
-Done
I recall that battery calibration was bogus, there was a post which explained why it was bogus in detail. In other words, don't bother, but charge your battery around 50% if you want a healthy battery.

http://bit.ly/KZdfJJ - Why cant you just google it like he said?
also you can go to recovery and select wipe batterystats.bin
Calibrating your battery does not give you extra battery life, just improves the battery level indicator. Android calibrates battery itself anyway (when battery info change to a few seconds)
batter calibration is of no use i have tested it many times on many roms. our ace has not a good battery. so follow common steps like brightness to 0, application background off etc etc.

thnx will do as u suggested
There is a way to get good battery life in miracle v4 but it took me about 5 days now I get 16 hours off battery with heavy use and about 22 hours for normal use
How I did this
1.let your battery totally die
2.leave your phone off and give full charge
3.still with your charger pluged in boot to cwm recovery
4.now select advanced then wipe battery status
5.now still with with charger pluged in reboot you phone
6.when your phone is fully booted remove charger(you will notice the battery will drop to about 86% in about 10 mins the first time but will get better each time you repeat all these step)
NOTE:I have done this on my wife's s.g.ace with rom miracle v4
And on my Sony Ericsson x8 with many different Rom's
And on my friends Sony Ericsson x10i with many different rom's
YOU MUST USE MAINS CHARGER NOT USB FROM P.C OR LAPTOP AS USB WILL ONLY TRICKLE CHARGE.
If this helped hit the thanks button

And samsung say no update to ics but there are working ics Rom for ace so are Samsung thick or are the devs here from menca ie. People with a IQ of 200+ also was it not google that said android would be lag free from 2.2+ and if that's the case what is the point in developing faster rom's of which all rom's here
Are faster then stock thanks to all the developers that work hard to make the android experience much better
From me to you via a sonyericsson x8, xda premium, the internet, and now its on your screen
according to the miracle v4 developers the battery indicator doesn't indicate about the battery properly ...will charge now to the max even after 100 % and will let you know what happens
I know battery calibration is useless, but how can ace have better accurate reading. And my problem is that whenever my phone deep sleep for a while and i start to use, the battery decrease rapidly after screen in for a while. Its like the battery is leaking even in deep sleep. Is this a common problem for ace user?

Calibration does not improve or increase battery life. It would just help in getting a more accurate battery level reading. Or so i read somewhere.

I have a question. My battery gets to 4200mV around 80% which means its fully charged.it continues to slowly climb to 100% after that even though it hit a full charge long before it says 100%. I tried battery calibrator but it doesn't seem to help. what should I do?
Use wifiwhen possible. Turn off all unused radios (GPS,wimax,data,wifi)
Also don't run Max brightness when screens on.

If you want a phone to last you six days, u better get a flip phone.
Unless you airplane mode the phone and never use it you will not get more than two days max, which is pointless since its not really a phone in that situation.

I think full charge is based off the mAh not mV.

I dont know how the circuit in the phone works, but when I charge up my lithium batteries for my RC car, while its charging the circuit shows a higher voltage than the battery will actually be at when its pulled from the charger. I also dont know what tells the charger it is full(or getting full) but the charger starts charging at a lower amperage the closer to full the battery becomes.

Grab battery monitor widget and better batter stats. BMW updates every min, but can be set lower. BBS is on of the best apps to show what's using battery.

Thank you so much. I will try them both!
Edit-I installed better battery widget.only problem I'm having is it shows me running an 1500mAh battery. I sent the dev a email which they say to do if its showing an incorrect value. So this should be fixed to. It works great thanks again so much. I now know one more thing about my phone that I didn't before
IIRC The SAMOLED+ pixels are off when displaying black. Google pure black and set it as you wallpaper. That should help.

Also depending on how aggressive your overclock is since it will raise voltages depending on frequencies. Also syncing data is a huge battery drainer. If you kill auto sync and only do manual syncs, it will feel like night and day.

Hello all,
Am i the only one that is having problems with the battery life on the galaxy gio?
I charged the phone today at 5 in the afternoon, by 8(3 hours after) 70% of battery, charged it with the wall charger and i rebooted it when the battery was full to close all tasks.
In 3 hours without any wifi, only 1 sms received, no calls and no other tasks was executed i lost 30%.
What can i do to improve the battery?
Are you experiencing any similar problems?

You can wipe battery stats, and turn things like gps wifi data autosync unused apps etc off, for some things you need root acces

What rom you have ?
I have problems with battery life too...but because i play games. Is weird because you didn't do nothing like browsing or play games and your battery was eaten.
Try a full wipe.
Also search the market for PowerTutor, it might be able to help finding what eats your battery, as what you describe this is not normal.
If you've rooted your phone you can calibrate your battery. There's an app for this in the market. It just wipes the battery stats file and creates a new one. I've head that it is good with every rom change to calibrate the battery Hope this helps! GL!
Actually it's good to flash every new ROM when you have fully charged battery. If you fail to do this you'll have to calibrate the battery and it might not be easy to do right the first time.
SO much easier to flash having full power
Battery stats wiping
IIRC google denied that battery stats wiping would actually increase the battery life: http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
I assume, you have things like WiFi, BT or GPS turned off... Then you maybe might try another launcher. Samsung's TouchWiz is quite a power eater.

It won't increase battery life, true, but think - when you unplug the charger? When your phone says "100% charged", right? And if your battery starts are wrong the phone may say "I'm charged" when it's actually, say, 40% charged or whatever.
Wiping stats should also provide more accurate battery indicator when it gathers new stats after some usage.

In my experience the battery indicator may work a bit odd (e.g. it goes fast to 40% then stays there for ages). But it didn't keep the battery from charging to full, even when it indicated 100% it still kept charging. But to stay in the topic, clearing the stats might help the "dropping by 30% really fast" issue
Yup, that's what I was talking about - wiping stats won't improve battery life, but might fix indicator accuracy
It could be your background applications eat too much mobile data. Check out your background applications and disable them. Stick with 2G also it improves battery life a lot
if the phone and battery are ok, and you don't have Wifi/BT/3G/EDGE/max_screen_brightness/ or high CPU usage background apps, you should get something like in the attached picture:
AT least for me CM7.2 really improved battery life up to 2 (TWO) days!
Unfortunately CM9 ruined this again and brought it back for ~8h...

You can use CM 7.2 http://forum.xda-developers.com/showthread.php?t=1381355
It is stable and saves battery better than stock rom.
Another thing to check is that Wifi is set to disable when the screen turns off or when plugged in... If not, you can loose 50% battery life in 6 hours. (Which i did once. NOT FUN.)
As well, apps that sync in the background. Ie, mail checking your inbox every hour for new mail; facebook, twitter, myspace checking for new notifications every hour; leaving apps using GPS running in the background like Navigation, My Tracks, etc. Those sorts of things can drain a battery really quickly, beacuse it has to wake up the phone, get the phone to get the required data over the cellular network then go back to sleep again, instead of just letting the phone sleep.
Another thing you can do is to make sure you kill apps. IE, don't use the home button to exit the app, use the back button. That will kill the app instead of leaving it running in the background.
Its kinda funny, this is all stuff people have mentioned already, but it seriously can be the difference between a half a day and a whole day on a battery...
Hello guys...I am new to this community as i recently registered to XDA...but i know maybe a bit about our phone Galaxy W GT-i8150....That could prove useful to Starters......
Now...mostly Users have problems with battery when they flash new ROMS....the reason is....their battery stats...for example if a person flashed a new ROM with 60% of battery....the phone will detect 60% as 100% and battery will drain quickly.....but You guys don't need to worry as i have found some ways to rectify this problem....Battery Callibration...yes u need to callibrate your battery in order to get long lasting batteries....there are some ways of doing it...most easy is through an app found in play store....Battery Callibration by NéMa...you just need to charge ur phone at 100%....and go to app and click 'Callibrate' (with charger plugged on!) ...and this will reset ur battery stats....it is recommended (not necessary) to drain out all the battery after callibration and Charge ur phone from 0% to 100% without a gap....
As i am a newbie...so i cannot post outside links...however if anyone needs to get more of it...he/she can PM me at any time and i ll try my best to help...!
I hope this post would prove useful to all of you.....! :good:
I have that app. Never really used it lol what happens if I calibrated it like a 50 wouldn't that mess it up?? So technically it is necessary.. idk lol I'm def no noob but I don't quite understand this app. Batt life seems the same after I calibrate battery (last time I tried)
Anymore info!!?!?!?!

You shouldn't uncharge your battery to 0%.
For calibrate your battery just charge it to 100%, shut down your phone, let it charge to 100% again, go to CWM, advanced, wipe battery stats, before wipe unplug USB cable.
I realize that..I'm just confused about this battery calibration. Doesn't make a difference for me..and yes I agree I never fully discharge me phone. Bad idea
Sent from my SAMSUNG-SGH-I717 using xda premium
I don't know about the ROMs the op flashes, but if my battery is at 50% when I flash a new ROM it doesn't go to 100% more like between 47-50%.
Besides the fact that battery calibration has been explained away as a myth, I can also state "calibrating" battery has never increased my battery life.

That has nothing to do with the battery and everything to do with being careless when plugging or unplugging.
OP, you may want to google or wiki the latest battery technology. Those 'tips' (b) and (c) you mentioned were good for NiMH batteries. Nowadays, we use Li ion or Li polymer batteries which do not need to be fully charged and discharged to maintain longevity.
Sent from my GT-N7100
Two things are important for prolonging your battery (lithium based) life: charging level and depth of discharge. avoid charging to 100% as much as you can, and also avoid wide discharging range.
A good strategy is to charge what you use, that is, if you use only 50% of the capacity every day, then only charge to 80% and use it down to 30%, then recharge.

It isn't. It's just more FUD about batteries... *sigh*
Listen people. It's -really- very simple. There are no tricks involved. Just drain your battery how you like and charge it how you like. These phones are designed for average people in mind. People who don't have a CLUE about having special discharge/recharge routines. They're designed to be charged whenever the user wants to charge, to 100% or not, as the user likes. The hardware within the charging circuit and battery itself will protect it from harm.

Re: Please help with my battery problem..>.<
Your problem is NOT ROM related. The poor battery is a common issue with the W. I had my W for just over a year, and when it was claimed by my Son, it was on it's third battery....and I can confirm that I was experiencing similar performance issues to you.....the first battery failed while I was still running stock GB, so again I say your ROM has NOTHING to do with it....
Even if your battery isn't bloated, the fact that it's giving such poor performance is a clear indicator that it's time to replace it......

I had exactly the same sort of problem recently, especially the inconsistent battery level, although for me it showed up most often when taking photos using the flash.
The bottom line is that the battery is totally stuffed and needs replacing. I spent weeks trying to sort the issue out and no matter how many re-flashes of the ROM and full calibrations of the battery I did, the only cure was a new battery.
As soon as I had a new battery fitted and fully charged all the problems ceased straight away, I now get 1 - 2 days of use from a full charge and no random shut downs.
The old battery had started to swell, but was barely noticeable unless the battery was laid on a hard, flat surface which highlighted the bulge that had started to form near the bottom of the battery.
that's why unless you need to travel or are expecting a full day without access to a power plug, charge your battery to around 60-70%. This will reduce stress on your battery and it will bloat in a much later time xD!
on a side note, current rating of chargers will only affect the charging rate of your battery and will not cause any problem to its battery life. so high current charging is good ! (by high i mean 1A or 1.5A instead of the current 0.7A ones that Samsung gives us)
