I am getting odd battery stats. I am pretty sure it is a calibration issue but wiping the data or running calibration tools seems to make no difference. Am I flashing something wrong? I make sure to wipe the data each time. It's not a huge problem but I would love to have a more accurate record.
charge to 100% and wipe your battery stats in recovery

I will give that a try. I thanks for the reply. I am learning above my curve but it's fun.
hahahah no problem! But just remember to let it fully discharge then charge it back to 100% without break and after a few battery cycles it should be good

Could someone explain to me the HOW, WHY, and WHEN you would use this in bootloader?
My battery is sucking hard ever since the latest update of MIUI and i'm hoping this might help if it's used how i think it might be used.
If your battery is losing charge quicker than normal, check if it's the kernel you're using with MIUI and try an alternative. Otherwise, wiping battery stats is like a recalibration to more accurately reflect battery charge. Charge battery to capacity, boot into recovery, wipe batt stats, then reboot, take off charger and run down battery until empty. That should reset your stats.

Should i run it down as quick as possible (ie. Full brightness, playing movie, LED flashlight on, ect...) or run it down with normal use?

Doubt it matters.
Another thing you can do for your battery is a full charge and run down till it dies 3 times. These are "smart" batteries and will reset that and might help you get more from it.
Also remember when flashing a new rom/kernel combo give your phone some time to adjust before judging battery life (maybe 2-3 days).

lithium ion batteries have no memory....

The batteries in these phones have a memory in the form of a charge monitor circuit. Those circuits remember the charge state of the battery and report it to the phone. This is why it is called a "smart" battery because of the chip that holds this data.
Li-Ion batteries do not suffer from traditional "battery memory" by way of crystal growth and the like (such as with NiCd batteries), but the circuit WILL remember the charge state over time due to the fact that it compensates for the voltage output droop which naturally occurs over time.
The procedure I posted previously was recommended to me by the battery manufacturer to extend battery charge over time.
I charged my battery for three house after i the light was green at 100% took it off the charger at 12am went to sleep woke up 311am it on 76% what went wrong? I just got the battery yesterday
wipe cache, dalvik, and battery stats then reboot, let your phone charge all the way and dont charge it again till you hit like 20% left on the battery, then charge it full again. this will make your phone start learning the way the new battery drains, usually if you change batteries you need to wipe battery stats.
also get the bmw ...battery monitor widget it shows voltage and how much draw at what time...and set batt capacity to 2600

yeah i just did that like 15 mins i was thinking that was the problem
WHERE CAN I find recovery at because I don't see it?
recovery
sorry bro i assumed you knew a bit more, first of all to enter recovery you must be rooted.
know if you are in fact rooted to enter recovery you need to turn of your phone and press volume down while pressing power until your phone shows a white screen give it a second to load, now on that screen you should see recovery, the option to wipe battery stats should be there
im not rooted is there any other way i can do it or how long does it take for me to get rooted
man getting rooted isn't that hard, but its not for everyone, so what i would recommend is you use your phone normally and try to run the battery down to like20% left before you charge it for at least 3 charges. so your battery gets used to the charging cycle, also dont let your battery go below 10% ION batteries dont like it. also make sure you don't have any apps running in the background eating up your battery, juice defender works great on battery life, but if you think you are savvy enough to root click on my user name and send me a pm and ill help you
I'm charging my battery and it always stops at 99% and can't go pass 100%. It use to be able to but then I flashed a rom when charging and then clear the battery stats.
I know there is this thread: http://forum.xda-developers.com/showthread.php?t=755903 to fix battery problems however I can't reach the first step of having it full charged 100%.

I think this has to do with some kernel mods some devs made. There's a trick in the dev section where you can make your battery charge till 100%. Not sure though that it's caused by this.

Hi, i wanna know whats the best way to wipe my nitro and whats the order
i usually do it like this:
1. wipe factory reset
2. wipe cache
3 wipe datvilk
and thats it
i saw many option like wipe battery statts and fix permission so when i have to do that?
thanks in advance!

That is the right way to wipe your phone... Battery stats wiping is done when you want to re calibrate the battery (mostly done with battery life isnt that good as experienced by other users)

From what I understand, calibrating the battery does little to no good; and wiping battery stats should just reset the battery consumption stats. Same thing as a full charge does I believe.

i believe that is a myth created because people wipe battery stats but don't perform the rest of the steps for calibration.
You are supposed to wipe battery stats when the battery has a full charge.
then you let it completely die.
then you charge it back to 100%
when im doing mine to make the process fast, i just wait till a night where my phone is fully charged, then i go into CWM and wipe the battery stats. then i boot up the phone and open a long movie file (2-3) hours preferably. this will drain your battery fast. I run the movie file and restart it when it ends until the phone dies (dont turn it off at 1% let it die).
this is where the calibration comes in. when your phone is not calibrated right you will notice it sits at 1% for 15-20 minutes even while playing a movie. once the phone dies.
i plug it into the charger and let it charge with the phone OFF, overnight. this will allow it to trickle charge to maximum charge. when you wake up in the morning your phone is fully calibrated. you will notice that it will actually stay at 100% for a few minutes after boot. this means its calibrated properly. (if you have an old battery it might not sit at 100% long, but it should atleast read 100% when the phone is booted. a poorly calibrated battery will read somewhere between 95%-98% after booting up from a full charge.
at least this is my experience with it.
i have done this alot because i used to have to use 3 batteries and calibrate them all. I ended up throwing out one because it was never holding a proper charge and i use my 2nd best battery for backup now and i stick with the one that holds the best charge.
*edit* a side note the one that doesn't hold a charge is because i had the phone in the sun one day and it overheated. overheating is the worst thing for a li-on battery (or most batteries at that).
side note: if battery calibration was a myth then every phone manufacturer wouldn't have warnings about how to perform 1st charge. remember they always tell you, let the phone fully die, then fully charge it while off. They tell you that becuase it is part of properly setting the battery stats.
I am not an expert on all this but i have read a bunch of threads by experts, and the proof is in the pudding... my battery life has steadily increased since i started following that advice.

i believe people say calibration doesn't work becuase they wipe their battery stats then they dont let it die properly. This is actually counter productive and tricking your phone into thinking your battery is dead before it is. then people actually get worse batterly life and conclude that wiping stats doesn't do anything. also if you didn't fully charge it would trick your phone into stopping a charge early (because overcharge causes battery damage).
improperly done you would end up with a battery that does not fully charge and tells you its dead before it actually is.
^ not an ideal situation.

I was just putting that out there. I personally have attempted calibrating my battery like you say to do; calibrate on full charge, drain all the way, then fully charge while powered off... I haven't noticed any benefits whatsoever. I've always been able to charge to 100% and I assume that with my chronic ROM flashing and bad charging habits that if it were required, I would have noticed some kind of negative issues by now. CM9/ICS is still better on battery than CM10 or any of its variants could ever dream to be. I got my Nitro in December of '11 and I've been abusing my battery with reckless abandon ever since...

Lay off the Kronic, man and follow the story. But seriously; you were saying that the thought that battery calibration doesn't do anything is only because most people don't follow the proper procedure. I was just pointing out that I abuse my battery to no ends and have only ever calibrated it once or twice using that procedure and have yet to see any ill effects from my rampant disregard for the battery without semi-regular calibrations; and that I never noticed any effect whatsoever from the calibrations. Just carrying on a discussion; or are forums not meant for that?
I would add wipe /system to that list, since we re talking about FULL wipe.
Oh and yea ... wipe battery stats is the least of your concern, i keep reading it doesnt do anything ... also tried doing it manually by removing the battery (its a whole procedure in a post i read) and i didnt see any difference, well obviously it will never affect the way your ROM reacts or works, even for the battery %.

Depending on what recovery you use:
CWM: Mount and storage > format system (or wipe system, same thing)
TWRP: WIPE > System
*****
So in order, FULL WIPE: Factory reset (wipe data), wipe cache, wipe dalvik cache, wipe system

Thank you! I gonna start doing it like this nos on
Even google engineer said that wipe battery stats did nothing at all, however, I do have some luck with battery calibration on other devices, and the difference is noticeable.
P930 seems to be fairly accurate on battery indicator and I haven't done a calibration yet.
the real question is are google engineer's experts on ni-mh batteries or software developement, that is the question the guide i read about it was written by a battery expert, while its possible they were just blowing smoke i have a hard time believing it does nothing. What would be more believable is that most batteries don't need calibration if they were properly calibrated on first use. All i know is i had 3 batteries going in and out of my phone for a few months and when i started doing calibration i got 4+ hours of extra battery life. It may have just been because i was swapping batteries that the calibration was messed, my only point was that if a battery does need calibration that is the method i've found that works. if it doesn't need calibration then calibration will do nothing, that is most likely why everyone says it does nothing because MOST batteries don't need calibration as that google engineer probably knows these phones and batteries do a decent job of staying calibrated. but you also can't say calibration is a myth because the facts are every battery manufacturer has a huge warning on how to properly first charge a batter (same thing as calibrate) upon first use of the phone. I would imagine they have these warnings so that people don't need to worry about calibration later. I don't know im not a battery expert, but i do know logic when i see it.
This is the G+ post by the Google engineer
