do you have to recalibrate battery stats with the extended battery or does battery stats take a back seat to the fuel gauge chip in the battery? i haven't received mine yet but am very curious.
Just received my extended battery today and wondering this as well. Anyone?
I'm thinking of getting the VZW extended battery and I was wondering about how the phone will handle different sized batteries especially if I'm switching back and forth.
I'm under the impression that the battery indicator shown on the phone is an estimation based off time to charge/discharge the current battery.
So if i get an extended battery, and the battery indicator is estimated off the extended battery discharge rate, would putting the original battery make the phone think it has more power left than it really does?
that is what we are trying to find out. if it automatically picks up the battery through the chip and does it automatically adjust battery stats or do they have to be redone.
Doesn't hurt to just wipe battery stats.. takes a few seconds..

How do you do that?
Boot into Clockwork Mod Recovery -> Advanced -> Wipe Battery Stats.
But be sure that your phone isnt plugged in into the charger, and it should be charged to almost max.

So do we need to wipe anytime we switch batteries once fully charged?

I wouldn't go that far, but install something like Battery Left which lets you keep profiles for more than one battery in case the stock battery meter is a little wonky.

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
hi all! ive recently upgraded my battery to a 2300mah one, and the os recognizes it as 500mah (according to /sys/class/power_supply/battery/uevent). have tried calibration, battery stats wipe, and letting it fully discharge, and then charging fully while switched off. have read about a method: letting the phone fully charge, switch it off, disconnect charger, pull out battery, connect charger, put in battery, and let it charge again fully. this didnt work either. the real problem is that whenever i charge the phone, it drops to 1% in about 5 hours, than it gets stuck, and i can use the phone for 1 day after that (with wifi/3g/bluetooth/gps on). this means i get false battery percentage readings. has anybody any idea on how to solve this?
In CWM, there is a menu you can erase the battery history. Erase it when your battery is at below 10% and recharge it to 100% plus another 1 hour at full charged.
There is a selling of 1700mAh gold battery for Defy and this one is pretty good and almost rated working like the genuine OEM battery.

do you mean wiping battery stats in cwm advanced? already done that a thousand times in thousand ways, but that only deletes the batterystats.bin. thats just battery history. i have an upgraded battery, i wanna clear ALL info about the old one. wiping stats just wont do it. but thanks anyways
please help, 5 friends of mine have the same issue with the same battery, and we have no idea how to solve it (even reflashing the kernel didnt work). according to battery monitor widget, the battery dies when its around 3100mv, and does charge till 4200-4300mv. and afaik the percentage reading are calculated from the voltage. so is there a way to reset the default voltage/percentage values?

hey everyone! I bought an extended battery from sedio a few weeks ago and I noticed that the battery percentage doesn't display correctly. It shows normally from 100% to 0% but then it stays on 0% for at least 6 more hours before dying. I've tried different roms as well as clearing battery stats and nothing seems to work. does anyone else have an extended battery with this problem or a solution?

nobody has any advice?
There's a battery calibration app somewhere on here. That should do it.
there are a couple of guides you should try out as well on here that will help you out. basically with phone off charge it to 100% the while it is still pulgged in pull the battery and and put it back in leaveing it plugged into wall charger the whole time. it should show back up with a low percentage let it charge until it stops (takes a while) and then clear you bat stats and calibrate with battery calibrating app. that what i have done with my regular battery from time to time when i have batteyr issues and it always seem to work like a champ. do some searching on the forums though and you will find step by step on how to do it

Thanks I will try this soon!
I've tried the above steps after reflashing a new ROM to no avail. I'm starting to think the phone won't physically recognise the bigger battery size. Any other help?

I would try charging the battery to full, than while plugged in pull the battery. The phone will reboot and eventually show a battery symbol with a question mark. Charge the battery for 2-4 more hours, than boot into recovery (if you have) and clear the battery stats. If you do not have recovery than use one of the many battery calibration apps that are on the market. Hope that helps!
Again tried what you said and still no success...

Have you tried widgets/apps such as Circle Battery Widget or ChargeBar? They might be able to read the actual battery life as the default one will not be setup to know your extended battery.

Yes nothing will work i am having a similar issue with my phone OEM battery 1880mah and the phone is only recognizing it 500mah.you can also check that if you have a rooted phone by viewing charge-full-design in sys/class/power-supply/battery and it can only be changed with the correct mah of the battery if we can some how modify the kernel or battery driver.
This has been covered in the Mugen battery thread. Its nothing to do with calibration, it is a hardware limitation of the Atrix. The battery status indicator covers the first 2000mah of the battery, from 100% to 2%, all the further capacitance of the extended battery (1200mah for the Seidio and 2800mah for the Mugen) the phone usually shows 1% battery charge.
You can use Light Flow to turn off the annoying flashing red led.
I bought a new battery today, a Chinese knock-off battery which claims to have a capacity over 2000. I live in Mongolia, so that's basically my only option if I want a replacement battery, since there's basically no postal system here.
When I first put in the battery, it showed a 59% charge. After a few minutes and maybe a reboot, it showed a 20% charge. It consistently drained down to zero, and I'm charging it now.
I've experienced really strange battery drain with the former battery (also a Chinese knock-off) where it loses maybe 10 percent an hour on idle, so I figured the battery needs to be replaced. Is there anything I can do to calibrate it? I have a feeling that the charge is actually more than is being shown, but no way to confirm my suspicions. Am I right just to try to charge it to 100% and discharge it to 0% until the battery life gets better, or is there something else to do? I should mention I've tried resetting the battery stats in CWM with no real effect.
Thanks from Mongolia.
Go into recovery when battery is at 100% and go to advanced then clear battery stats or download battery config for rooted devices and clear battery stats that way.

Clearing battery stats achieves nothing other than deleting the stats on the what has been using battery power. Battery calibration isn't required on our phones.

if you want to increase battery life for your new battery, charge it fully to 100% whenever you charge it will increase charge storing capacity of the battery

Never, ever I repeat never let your battery drop below around 5%, and always charge it before it reaches zero. I use the Guage Battery widget v3 pro as it is very accurate, but you can also get the free version. You can & should use the free battery calibration tool from the Google play store, simply install it & charge the battery to 100% then run the calibration App. simples
