[Q] Wipe the battery stats am I interpreting this right?

I have allready read:
Battery recalibration (Thanks to Cyanogen for this and to fachadick for bringing it to my attention).
If you're experiencing higher than normal battery drain, try the following:
1. Charge the phone to full battery; let it keep charging until the battery says it is fully charged. Do not just wait until the light is green, it isn't always fully charged, causing a lot of inaccuracies. (You can check by going to: Settings -> About Phone -> Status -> Battery Level = Full.)
2. Boot to recovery and wipe battery stats.
(To have the most accurate of battery stats, reboot the phone immediately after wiping the battery stats and wait for your ROM to boot completely to the desktop. Once your entire boot is done and you have full access to the phone, go ahead and pull the charger and continue.)
3. Do not charge the phone until after draining the battery completely, resulting in it automatically shutting off. Take out the battery, and keep trying to turn on your phone until it will not turn back on at all.
4. Recharge the phone completely and then use as you normally would.
This is a method that has been proven to work, I am sure there are other ways. My battery lasts longer after doing this and the reading is much more accurate. It might be advisable to do this after every ROM install if you want the most battery life and most accurate battery reading by the phone's software.

My question is dose the phone need to be off or on for stage 4 the recharging of the battery?
If it can be off for stage 4. Dose it need to be charged in one sitting or can I charge it partially then take it to work and then charge it the rest of the way before I turn the phone back on?
This my second attempt at doing a battery stats wipe. The first time I tried I left the phone on wile charging and the battery only charged to 3800mV calming it was at 100%. I had to bump charge it 3 times over 3 hours before the battery was up to 4100mV-4200mV and clmaing 100% charge capacity.
Evo 4g Ur3 Stock root Seidio 3500mAh extended life battery.

1) You can have it on
2) NO! charge it from 0-100% in one sitting
I did it according to the above with my 1&2 and im getting accurate readings now as well as the battery life i should have.

I wonder if this means that I will not be able to have proper battery stats as my phone likes to stop charging and claim that it's at 100% when its actually at 50-80%/ (It dose this 95% of the time... It even did it with the stock battery stock battery a couple of times)

[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?

this is what you need to do for recalibrating the battery with the phone on

If you want to charge your battery while it is off, reinstall winmo.

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.

[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

Like I told.
Sent using Tt.

Y u no sleep? help me, thanks.

Hello, i'm currently with quarx CM10 last build (2 nov). First time i installed it i noticed it help A LOT with battery consumption.. from 12 midnight till 10 am from the other day it went from 99 to 97... that is.. like a miracle. then i did something stupid.. i used "battery calibrator" and it ruined it. Today it wen from 12 to 10 am in the morning with 99 to 60 then 49 (typical battery jump)...
I repeat, it's in the night, were wifi is off, refresh is off and nothing (that's what i'm planning to discover) is running or updating.
I attach some screens.
1) first install of the new rom. you can see it sleeps like a baby.... plain.
2).. goes down.. and down... even though i'm not using it.
any comments, help or suggestions? thanks in advanced!

Make your phone recalibrate the battery. Follow the following steps:
1 Use the phone till you have 10% or less battery left.
2 Wipe battery stats from 2ndinit recovery.
3 Boot into CM10.
4 Charge your battery to 100%.
Doing this will make the phone generate a new battery stats file and should solve your problems.

i'll try that. but already done it when installed the last build for the second time. i do wipe cache / dalvik / batt stats then flash ROM and all over again with the wipes.

If you've uninstalled your battery calibrator app or if you've not used it after the wipe, then you shouldn't have any abnormal battery drain...
If wiping battery stats doesn't work, then most people recommend reflashing the ROM, but you've already done that, so you shouldn't have the battery drain now.
Just put your phone to sleep for a few hours, and let's see what happens after doing that.

This is what i did after seeing the sudden drop the other night:
- let it drain normal till the day finishes (at midnight, that's when i did the following)
- charged the battery to 100% and turn off phone.
- pull battery., connect charger to wall and recovery.
- install ROM without battery on. Wipe cache, dalvik, stats batt, install rom, wipe cache, dalvik and statts (again)
- boot into cm10, turn off screen and went to sleep.
- THIS morning, i saw it drained me up to 60 all night.
...
so as you can see.. i've already seen that after reflashing nothing has happened.
no, i didn't use again the calibrator.

I'm not 100% sure, but as far as I remember, the battery stats gets generated while CHARGING a drained battery.
That's why you should drain the battery, wipe stats and THEN charge it to 100%. As it charges, the battery sensor detects levels (15, 30, 60 and such I think) and generates the battery stats based on these readings.
Afterwards, based on these stats, it generates a reading of battery drain, as the battery sensor itself senses only certain levels.
So, drain, wipe and THEN charge. Do this and let me know if the problem still persists.

hmmm! never tried that!.. i was just charging it and it's in 90.. so i'll let it drain and tell you later thanks for that suggestion.
Still open to other comments though thanks to everyone who reads this.

Just read and engrave to your memory folks! Battery calibration never ever had a positive effect on the battery life and the battery usage shown in the android in-built "Battery Use"-app... and by the way, the stats are reset every time you unplug your nearly fully charged phone from the cable.

Hey, rather than blaming your battery stats I'd search for a process running all the time. Looks like something is keeping the phone awake.
The battery calibration IS A MYTH, as explained here, so don't waste your time wiping the values in Recovery. If you don't find any hyper-active processes with the following procedure, the drops might be related to a worn battery (I don't know how old your phone/battery is).
Open a terminal console and type:
$ top -n 1|head
(if you don't have Hacker's Keyboard installed and selected as Input Method you might need to copy and paste the line above, off course without the dollar sign).
Look at the processes listed as output and paste them here.

Hola slim , thanks for answering. here's the screen

You had it coming since you are using Swipe... It's chewing up your CPU, and consequently your battery. Search the site. Off the top of my head I think it was a common issue.

Swype? really?? shoot.. i love it.. even though i don't use it that much. Searched a bit but couldn't find much. Gonna try freezing it and see what happens. thanks.

Finally i managed with your help to accomplish some good sleep! here's the screen. i think it's awesome, never ever seen this.
thank you!!
we'll see if it gets better.

There's an interesting lesson to be learned here: if no deep sleep can be achieved, don't blame the ROM, and look for a stubborn process which refuses to stop when the kernel tell is to.

no, i guess that it can not be the cause
battery calibration apps are useless... wipe cache, let your phone discharge to minimum percentage and then charge it to full continuously, then unplug when it reaches 100%.
if not, try another battery, it may have bad cells

its problem to ur battery only ...to fix problem permanently try change battery and bye new (gold power) with big mah ...
on restart of phone they powered off by default and not powered on before u put in charge or replace battery ,it work better try power saving option and install old bootloader via odin (if u dont like to change with new one) ...or you can start ur phone on safe mode than calibrate battery whait to charge 100 % and restart on normal mode with power saving enabled
