Hello,
for a past few weeks I have a battery problem At first my phone was shutting down at 30-35%, today at 50% :O :O
I know everything about battery calibration, I did it at changing the ROM and did it last week when my phone was fully charged, in recovery. Battery monitor widget says that capacity is 790mAh after two cycles of charging.
I also create new battery in Battery monitor widget and it says that capacity is 1480mAh :/
You can see that now my battery is at 14% with 4123mV, that is not normal
Can it be that my battery is dead?
Does somebody has other method how to calibrate my battery?
Thank you very much

I can see that you use Sense rom so jump at Droidzone site and download some of the kernels with full battery calibration (I think it's #22 and up), flash it and that would solve the problem.

Or flash an AOSP rom and go to the nexus one development thread to find the battery calibration thread and follow those instructions.

Hi!
I have a little question about calibration:
- After wipping battery stats, I have to do a discharge/charge cycle?
- When I made discharge/charge cycles, I have to wait 0% before charging?
I've to do this always? Or never charging at 0%? I've read it's bad for the battery...
Thanks!
I usually charge till 100% and drain it till 10-20% and charge it back up ive got decent battery life after 4 or 5 times doing this
charge your phone till current widget shows 0amp(dont rely on green LED)->switch off charge till green led is on->wipe battery stats & reboot->discharge till its 1% ->charge it till current widget shows 0amps,you are done.
this was what i had read somewhere and had worked for many
When it is necessary to calibrate, after flashing new rom? What about after new kernel?
Tia,

download current widget and battery calibration by damo software... put a current widget on the home screen.. when then the widget shows 0mA (dont discharge even if the battery shows 100%) once the widget shows 0mA(do not discharge) open battery calibration by damo software and delete battery thing.. i dont remember exactly.. once u delete... close the app and restart ur phone..
yes thats the way i do it too
why do i have to calibrate the battery?
I always calibrate my batterie after flashing

I always wanted to but never did
i always calibrate my battery after rom flash but i am not sure whether it really helps to improve the battery life..i do it just out of force of habit...
I really have to do it soon,to compare whether is it even worth doing it at all...
Hey,
My desire shutsdown itself at 13%. The Desire HD of my brother shutdown at 0-2%.
Ive tried to reset batterystats but it doesnt help.
What can i do?
Gee, I can't tell.
How about googling about it first?
It was Same on stock rom as i bought it newly (before 1year), it cant be because its old, and Ive calibrated it too, more Tipps i cant find there,
It is a problem with the battery stats. HOWEVER. I've read somewhere (cant remember where ) that even though its an annoying problem. Re-setting the battery stats will not improve battery life. It will give you a more accurate representation but the battery life will stay the same.
Instead of messing around ressetting stats just remember that 13% = dead battery.
just my 2c
Some batteries shut down with 13%, some with 20%, some with 1% and others with something between. As long as you did not notice a strange battery drain, I would just stick with 13% = dead battery (as already mentioned).
Ok, i asked because i thought it isnt normal. Thank its ok.
Thank you
I guess it depends on the battery. I have one that goes almost until 0% and I have another one that holds only until about 11% or so... 13 is not that bad!
My desire did this, except it shut down at around 20%. I just bought a new battery, not even an official HTC one at this fixed it. Now it shuts down at 0-1%.
So basically, its just the battery imo. My battery was about 1 1/2 years old and had seen better days.
Used to have this problem
When I used CM7.0.3 I had this problem, now running LeeDrOiD HD 3.3.3 with Sense 3 and it only shuts down at 2% or less.
i have same problem too
same here
Mine used to do this aswell. Reboot to recovery and clear battery stats? Then full charge and full discharge.
Worked for me at least.
Mythbusters to the rescue.
Like every desire user am having this problem too. I often switch between roms. Even after resetting battery stats my desire dies at 15% battery.

calibrate the battery ****s down at 0% then
I think, you have to reset the Battery Stats. For me it helps!
Lol.
It is not a problem any longer since theGanymedes published his great guide.
Notice how he never mentioned wiping battery stats?

... buit how can i fully discharge the battery if it shuts down at 13 or 20%? even if i restart the phone, it shuts down again
Mine just shut down between 45% - 48%.
Ordered a new one
Same here @ 18%, going to test some methods and inform you
You need to recalibrate the registers in the battery. There is a special program that does that.
Use this howto and it will be fixed.

BTW, you need to have Cyanogenmod or Oxygen installed for this to work or a distro with a kernel that supports it.
I hv flash a .sense Rom on my WFS and i used battery calibration, everything seem to work fine, but i notice the battery percentage indicator is incorrect.
Case 1:
I charge the device till full and run battery calibration, after few hours without using the device, the battery shown is still 100%. after that i run some apps n games, the battery immediately shown 96%, after few minutes the battery drop to 88%.
Case 2:
Battery shows diff reading after a reboot, let say I now have 50%, after 1st reboot it show 45%, I feel that is getting weird, then I reboot again, the battery show 48%..
Anyone know what is going on n any solution for that?
Thanks..
You have a miscalibrated battery...Try wiping battery stats via CWM...if it doesn't work try removing the battery for 2-5 minutes...with 4 minutes for me being the sweet spot...the latter solution works for me...try and test...
Battery stats doesn't actually do anything people.

Yeh all I've read about battery calibration in the past few months since I got my WFS unlocked and started playing around is that Battery Calibration is a pointless task that does nothing.
Anyone else find it amusing that some ROMs still include it as part of the initial setup?
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
