well, you should at least read a lot to get knowledge about how stuff works... and you obviously did not or you wouldn't call dudette a dude...

unless you have your own custom OS you just fogot step 8 - dance with rain stick around phone when it's charging...

I flashed Unnamed with Aroma, full wipe(s) no back ups and i'm having an issue sometimes when I reboot with between 60% - 90% I only have 10% - 20% once rebooted. So I would have to say that does not completely hold true even though it does make perfect sense.

So the "calibration" ritual may not actually calibrate the battery but it definitely is useful when having these issues.

Heres the deal doing this DOESNT improve battery life. All it does is get rid of "gremlins" in the file.

Better battery stats (that you can get here on xda) will do this for you each time you plug the phone in.

Yes it is. I was unaware of this before but hechoen brought it to my attention and now the op states that you should not fully discharge.
