I want to know that we normally calibrate battery when it is charged to 100%, but what if we remove batterystats when we are on 0%?
it will be the same as we caliberated when it was caliberated at 100%?
It's generally not a good idea to drain a lithium ion battery down to 0. They don't have memory, but draining them all the way can destroy the battery.

What I meant was as in if lithium ion batteries go all the way down to 0% they can never be recharged .
Never ever .

One day my phone got switched off automatically because the battery was very low and then I rebooted again and it got switched off again. Later, I was not able to reboot it. I wasn't able to go into Recovery mode either. And when I plugged in my adapter for charging the battery, nothing happened. I thought my phone got bricked and was all set to go into a Samsung Service Centre. But somehow, after 24 hours, when I plugged it again, the battery icon appeared in my SGA screen and it was charging. I suppose my battery got down to 0%. Isn't it?

So are you saying that if the battery really gets drained to 0%, there is no way you can recharge it?

i know but still just making sure that my battery is now needed to be replaced so doing anything i can with the battery...who know what may work..but i dont get one thing....if my battery is not working properly then it should drain fast rather than getting stuck on 70%...that's why i am doing almost everything with the software so that i am sure that my battery is not working properly and i wont be wasting money in buying a new one

I got my gs3 yesterday, and it came with about 50% battery. I charged it overnight, and am using it now...do I need to run it down to 0% then charge all the way back up to 100? Some say I do, but I thought li-ion batteries didn't require that. Also, should I run a battery calibration?
Thanks.

No, you do not need to do anything to the battery. Charge it and use it normally.
Also, battery callibration does nothing that your phone does not already do on its own.

No you shouldnt let it go all the way down to 0%. Lithium batteries are designed to be permanently charged. if you discharge it completely you can damage your battery and/or the capacity goes down. So the best thing to do is charge it and when it is full just take it of the charger and dont leave it plugged in :good:
Hope this answers your question

No, calibrating is done for you every time your phone charges to 100%. I promise.

Probably your battery is ruined, and I'm saying it being careful. I also had problems with my original one, they started small but with time they grew up and I had to change it. For me didn't matter calibration or removing the battery, it just got worse every week.
Dear friend, who testing battery from china, is very big mAh. Can we use phone on this one. Battery life really will be a bigger or not ?

If you do a calibration and doesn't work, change the battery with one identical (from a friend with SGSII, dont buy it =) ) doesn't work too... maybe is the charge center from the phone and is damaged; if is it, take your phone to technical support...
I hope you have warranty, and take off al modified ROM's and Root's things.
I had this for ages and it was draining my battery really bad and I discovered it started when I had my tablet plugged into an extended usb cable into my charger but it ran out of battery and wasn't the same since and just charging to 100% didn't get rid of it or rebooting or brushing the usb port (some suggestions I found on Google and Xda)
I searched google and xda for answers but didn't get any so what I did was charge my battery to 100% and then callibrate my battery and the wakelock disappeared
This happened with my note 10.1 but thought I'd post this here to help anyone who has this wakelock for the for the galaxy s3
Sent from my GT-N8010 using Tapatalk 2
Try to unplug the charger when phone is unlocked. Then reboot the phone. Now check in BetterBatteryStats for this wakelock.
I had this wakelock issue on my previous S2.

It happens when you use a faulty usb cable or extension cable and the phone or tablet doesn't charge but when you unplug the cable it still thinks it's charging but it's not, the vbus wakelock is a usb charging wakelock, rebooting does nothing I had the wakelock for two weeks until I got rid of it and when I searched on Google and xda nobody knew how to get rid of it

The battery is calibrated by normal use please read the stickied FAQs and guides .
Do I understand correctly, the normal using of the battery performs its calibration? No action need not be applied?
