Ive seen 2 ways to recondition battery...which one is the RIGHT way?

So which way is the RIGHT way to recondition the battery?
A. By Sombionix
1. Charge phone completely, leave plugged into power
2. Boot into recovery
3. Wipe battery stats
4. Reboot
5. Remove power cable
6. Drain that sucker all the way
7. Recharge fully
8. Rejoice!"
OR
B. By Someone else (Idk who, sorry if it is you)
1. Let it die completely
2. Charge it completely
3. Wipe battery stats
4. Reboot
5. Your done.
Which way is the right way?

I personally have seen the first one work pretty good on my old MyTouch3G. I have never done this to my Vibrant but like I said, the first option used to work for my other phone pretty good.

Theyre both essentially the same:
Drain to 0
Charge to 100 (while off)
Boot into recovery/wipe battery states (while still plugged in)
Then drain battery again (I don't charge my phone until its 1-3%)

I don't see how they are the same.

Sorry to hijack your thread, but just to clarify.
Does my phone need to be rooted/have a custom rom/modified in any way before I can recondition my battery?
I booted into recovery and couldn't find the option to wipe battery.

Basic drain, recharge, wipe, drain

Only the first way, the second way conditions, kind of, then erases the stats... :/

Yeah, I've been looking all over to figure out how to do this. I found this after some searching. I'm going to try this when I get off work.
Found this:
""HOW TO RECONDITION YOUR BATTERY
If your battery seems to drain fast, or if you are changing roms, you might want to try the following to help your battery. Master posted the following instructions (this assumes you have root and clockwork recovery):
1.) Drain your battery to the point it shuts off on it's own..
2.) Plug it in & let it charge over night (While it is still off)
3.) Launch into ClockWork Recovery by holding the "VOL UP", "VOL DOWN", & "Power" release those buttons after you see the second Vibrant screen.
4.) Press "reinstall packages" (It should take you to the Clockwork Mod Recovery screen, If it didn't then press "reinstall packages' again)
5.) Go to "advanced"
6.) Press "Wipe Battery Stats"
7.) Reboot
** I drain my battery to as low as it will go, but not all the way. I also charge it for only about an extra hour max, once it's fully charged. **""

so the only debate is whether battery stats should be reset when the battery is full, or when it's practically empty.

I've never wiped battery stats and never had issues, even switching between batteries on my G1. Just drain till out dies then recharge. I've had it last on 1-2% for a a few hours before, but it always recalibrates its self after the next full charge.

So are you saying we need to be rooted? To use the clockwork recovery?

Why are you guys insisting on DRAINING before CHARGING and then WIPING stats? The first drain won't do anything and even if it did, you're wiping the stats soon after.
Just charge, wipe, drain, charge. That's it.

where do you guys find the "advanced" and "wipe battery" option? im on a Tmobile vibrant and when i boot into recovery and then reinstall packages, i only get the option to:
reboot system now
reinstall packages
delete all user data
delete cache data
when i click reinstall packages again, it does a scan and says "e: cant open /sdcard/update.zip, Installation aborted"
thnx

You need to download clockwork recovery from market and flash the program within the application.

Just so we're clear "conditioning" the battery is a misnomer. Lithium Ion batteries do not need "conditioning" in the electrochemical sense that say Nickel Cadmium batteries do. What you are doing is calibrating the internal charging systems awareness of battery states.
I've tried either method, and cannot note any significant difference between the two. So long as your starting the calibration with a clean slate and a battery in an effective 0% or 100% state you're effectively establishing a baseline that the software can work with.

This.
And since it's a lithium-ion battery, you really shouldn't be draining it to absolute zero, ever. EVER. So if you're going to "condition" do it at 100%
I see so many people on these forums complaining about bad battery life and how they reconditioned their battery 27 times this week.
STOP.
The best thing you can do for your battery is charge early and often.

once battery is drained, instead of recharging it while its in the phone... will it be the same if i recharge the battery seperately, then when its fully charged... slip it inot the phoen and THEN do this again? i have 3 batteries lol

Thanks for this useful information. I have a desktop charger that charges my two spare batteries, so I don't use the phone to charge the batteries. Given that "conditioning" simply calibrates the phone, would this method help my battery life at all?

[Q] Charge HD2 while its off?

I want to recalibrate my battery, so for that i need to completely charge the phone while its off. as we all know we cant because of mgadlr autobooting. so how can i charge my phone completely and have it off?

why u want to do this with emulator?
it works easily with the recovery.
in my opinion it doesnt make so much difference, it should be important that you dont wipe battery stats when ur on 50% but when its only some % its not so important. we should wait until they fix it in magldr.

if you're gonna wipe the battery stats you should do it right when the battery is at 100% charged, so it can create a new one starting with the 100% value when you delete it, and run the phone down to almost 0% charge so it can set that value as lowest, and that should take care of that.

When I wipe the stats I type everything in the emulator while it is plugged in as soon I pull the plug I hit enter. I still get the no file found mesesage. And in CWM when I go to advance and wipe that stats I don't get the message batter stats wiped. Any ideas.

Battery display inaccuracy

This happens when battery level is below like 30% on my HTC Evo. I am using a customized ROM (Supersense). Whenever the battery reaches 30% remaining, it doesn't drop. However, if I use the phone for a while and restart it, the battery shows only 10%. Clearly, some of the battery management program does not work properly. Is it a bug related to battery itself (hardware) or ROM (software)? Anyway to fix this?

You could try charging your phone up fully then go into recovery and delete the battery stats(Under Advanced in CWM), unplug your phone and use it until it discharges fully and shuts off. Finally, recharge the phone fully again once it has died. I believe this will calibrate the software that monitors your battery or something like that. You can find more specific instructions on the net if you want. Some people like to bump charge and everything else to try to get it perfect but I never found the need to go to that extreme.

Download "battery left" from the market and it will recalibrate your battery. Also yes, I would reset battery stats as well but battery left will actually recalibrate it. Battery stats is how long the phone has been on, what's using the most battery, etc. Correct me if I'm wrong.

Just boot into recovery and wipe battery stats.

I had this problem once.
All I did was download "Battery Left" as VICODAN said and I flashed this zip that I got from somewhere on this site but I forget where. I had to change the updater-script and the binary but either way it works on our Shift. Charge to 100% and flash this, then with Battery Left install use the phone till it dies and after that, you should be golden.

battery calibration
U can try the app battery calibration also in the market. If you're rooted.
*Since we're talking about batteries.
I wish our phones would beep or set off an alarm when charged to 100%.
I was keeping battery calibration just for that, it has that option but only worked maybe 1 out of 20 times the alarm went off.

Love the app, so when i got to sleep or I am going to calibrate, I just open the calibration app throw it on charge, it beeps I hit calibrate unplug and done. That way I don't have to open the app when It's 100% or with early morning fuzzy eyes and fingers that don't work right

[Q] Battery won't charge over 60%

Since few days ago, im using PCFighters rom. And, I have problem with charging, my battery wont charge above 50-60%. I tried deleting battery stats from recovery; i tried bump charging (although i cant charge phone while its turned off - CM7 "feature" ), i tried some method form XDA (charge phone, delete battery stats, reboot phone, remove battery from phone while rebooting, and phone still on cord etc) - but nothing works...
Battery itself lasts like usuall, 24-30hours, but this is really annoying... and, here is pic of battery usage, you can see how it oscilates on far left side, while charging, 50-60%, and thats it...
Any solution?

There are 2 possible solutions:
1. Re Flash the ROM, let it reach all load until phone turn off, charge to 100%, then Calibrate Batt, then reach the load to 0% again, then charge the batt. If the charge stay on 60%, unplug and plug your charger continuously from the outlet energy.
2. Replace your battery with a new one.

this problem have a simple solution you must download "battery calibration" or "battery calibrator" and when the phone is charged (60%) you must click the button .. if this doesn't work you can enter in recovery---> advanced---> wipe battery states

Done this already, not working (both ways)... ill reflash ROM today, and we will see does it works
Edit:
Not working... flashed ROM again, cleared dalvik/cache etc, left battery to drain out - but it wont charge over ~50% :/

Thats How I Do It

I need to flash the latest recovery.img CWM v5.0.2.7 first and then wipe battery stats.

With Battery Callibration app see how high is battery voltage, when is at 60%, then share here with us.

OK, ill check it tommorow morning and type it here... thx, imenjak
("imenjak" - ppl with same name, in our language)

After 10 hours of charging, baterry is at 52% or 3729mV... i tryed unplug/plug in for a few times, but now it wont go over 52%.

Finally the following steps helped me:
- I flashed the latest CWM recovery.img v5.0.2.7
- Boot into Recovery and did:
- "wipe cache partition"
- Inside "Advanced" both did "Wipe Dalvik Cache" and "Wipe Battery Stats"
- Power Off
- removed batterie and waited at least 5 minutes
- inserted batterie and used GT540 until it's fully empty
- charged GT540 again
- Voila: "charged 100%"

If nothing helps, try to backup your current ROM, install a different one (for example Froyo or stock Eclair) and if the same thing happens (also after calibration) then you will know for sure that the problem is hardware nature and your battery is dying. But if on different ROM you have normal battery charging then its a very weird bug.
Good luck, imenjak!

OK, i have CWM V4.0.1.4; and never took battery for 5min or more.... first I will try with battery, than with new CWM; and on the end with another ROM... TY all for advices

Well, problem is solved... funny, but problem was in charger, or data-cable :/ With new charger, I have no more this stupid problem

[HOWTO]wipe Battery Stats

When i must wipe my Battery Stats?
Always when you Flash a new Rom or Reflash the rom you must have to wipe your Battery Stats to have the best Battery life from your Device.
How to wipe Battery Stats?
1. charging the battery FULLY
2. boot device to CWM Recovery
3. advanced/Wipe Battery Stats
4. reboot device
5. don't charge the device until the battery still turns off your device because it empty (do not drain with heavy apps like video streaming ect.)
6. now again FULLY charge without interruption
7. Have fun ^^
Hit the Thanks Button if it help!

Thanks
I have woundered why it didn't work on my phone and that was becuse i charged it while i wiped it and i didn't let it drain all the battery

well...you can also wipe that in the xRecovery if you have it
the reason of wiping it is because the battery status will not be accurate.
also, if you found your battery is draining, try to wipe it, then check the running services if there are too much apps running in the background~

wipe it when battery has 100% and after you flashed new rom

The better and easiest way is with battery calibration.apk
Download this: http://db.tt/Ohb9vGgP
And follow the instructions

actually, it usually takes a longer time for the battery to get from 99% to 100%
the reason is... idk...
but even thought it is 99%, it takes a shorter time to consume the battery than it is charged to 100%
thats my experience

If you read the phone manual, it says that happens because it is expanding battery life... (??)

what does that mean So after fully charge > wipe battery stat > reboot... what do I do now? I'm confused here

after you wipe the battery stats and reboot your device you have to wait untill your device battery is empty and the phone turned off by herself. 0% battery . After device turned off by herself, charge your device again to 100% without any interruption like reboot or unplug power plug.
Understand? Please excuse my english is not as well.

That's what I don't understand. After I Wipe Battery Stat and reboot the device. I'm waiting, and She's not turned off by herself but I skip Step 5. and everything works. still 73% after 2 hours ...

@azyar
1. Charge the phone (100%)
2. Wipe battery stats
3. Reboot the phone
4. Now use the phone until the battery has gone from 100% to 0% (when the battery reaches 0%, it will turn off by itself)
5. Now charge the phone 100% again without interruptions (don't even touch it)
When battery level has reached 100% (not 99%), you may use your phone again.
