    I doubt that the phone's manufacturer would say that rooting is the way to properly calibrate. In my experience, the method I mentioned works well and is the proper and only way for stock phones. The battery stats are correct as soon as the battery is charged fully. Can you explain how your method's "instant calibration" works and why it takes 2 days?

    It's true, the phone should prevent the battery from behind discharged (or charged) to the point where damage occurs. I should have said that people shouldn't try to somehow overly discharge nor should they try to run the battery down quickly. And on the other side of things, leaving the phone charging for extended periods ends up cycling the battery thus shortening the battery's overall lifespan so that's not a good idea either.

    Yes, I think Verizon recommends doing it every month. It stands for Preferred Roaming List or something--the phone's knowledge of the cell network or some such science.

    It's really not instant calibration at all. What it does is it wipes the battery stats off the phone as if the phone were fresh. Then you really need to do something similar to your procedure anyway - let it discharge well (it doesn't necessarily need to be until loss of power) and then charge full.

    So, it's instantly wiping bad battery calibration stats off the phone - a better description.

    I'm not trying to improve it I'm trying make my phone accurately read my extended battery. I don't want my phone saying 5% when I still have 5 hours left on it.

    Hard to believe this after owning multiple android devices different extended batteries and flashing roms for the past 3 years. Considering the length of time that I've been doing this, I can say that if you do not calibrate you battery after flashing a new rom or puting in an extended battery, it will not correctly read the battery and in turn cause your phone to die eiher before the battery is actually dead or before the % reaches 0 or like the post above said have it read 5% when it actually means 20%. I've encountered this many time BTW.. Would of been nice to have an explanation of WHY this happens. I also wipe battd not just batterystats.bin. Diane Hackborn is a reputable source of information but she doesn't give reason for current situations.

    I don't know about deleting battery stats, but the discharge/charge procedure I've outlined sure does seem to work for me. See here:

    Source: How to Prime Batteries - Battery University

    In other words, the phone figures out the battery's capacity and current state if you cycle it.

    I would suggest you take your questions to the google engineer who posted that.

    I think I would rather trust someone who has first-hand knowledge on the matter (the person who works at google on Android) than random people on the internet who offer little more than anecdotal evidence...

    lol....I like the comment about manufacturers caring about your calibration and whether you have to root or not. Let's be honest....Manufacturers would PREFER your battery to NOT be calibrated....that way they can entice you to buy a new phone, more chargers, or simply another battery.

    It's all about profit. Not quality of product, functionality, or ease of use.
