[T-Mobile Samsung Galaxy S II SGH-T989] RealPariah:
Hmmmm, is it possible for the phone / custom software to accidentally have an error of some sort that might cause it to miss a wipe and then begin to work from incorrect and/or stale data (or say possibly it lost power when trying to perform that function before it fully completed you think that might cause an issue)? Oh, yes computer devices are programmed by humans and are prone to errors we have to go back and fix. If software and/or hardware ran perfectly all the time then why do we have computer technicians or the need for multiple pieces of different software that do the same things in different ways?

Or I guess the multiple thanks people bother to write out in this thread after bothering to try something that takes a good bit of time to fully do are all lying to you too LoL.

(sarcasm)

Oh and I like to waste my time posting nothing but lies when it takes me days weeks and months of research, testing, and verification just to mess with people (/sarcasm).

I never said it was the secret Google way, I stated it is the best way I have found through experimentation and learning for this device in particular and is a shame Google seems to hide it as you only get wipe battery stats file (and if it were NEVER needed why would developers bother to spend time programming the function in when they could spend that time on other things? That among other things told me otherwise when I use deductive reasoning) file in custom recoveries or through scripts and can only be fully done after you root the device. I don't like that Google says it's not an issue when you can read the many replies people leave thanking me for creating the guide and it was only one that breaks it out and not only that attempts to fully explain it in such a way you understand, but also what you are doing and why in every attempt to be as thorough and transparent as possible (kinda like how I am trying to be thorough with this reply trying to give you as much information and be as transparent as I can to the best of my abilities (for instance can't account for your personal expertise, reading proficiency level, how much you are willing to read, etc. but am trying to be very thorough and transparent and hope this helps)).

I don't just say wipe battery starts because you get extra battery magically I have tried to best explain why you may want to do this if you are experiencing certain conditions, why, and how best to do it in certain instances, of you choose to try it.

I provide as much information specifically to not mislead people.

If you look I have explained there is a chip and yes in certain situations the file can get auto wiped (or restarted) for you, but sometimes it seems this does not always happen when it should so until you do it manually the effects seem to be cumulative.

I don't claim to know EVERYTHING about it, but have worked with batteries and computer systems for a long time. This sort of thing even happens to Windows (or other OS based laptops) as well and have had to do things like pull the battery if the device can remain powered and in Windows while doing it then re plugging battery in after a couple minutes. Which can help fix statistics issues with laptop batteries by the way. So some of it is just also personal experience.

It is not easy to find reliable (truly good reliable extensive) information on android system and battery interactions, so I did find some, used that my own experience, my device as a lab rat. Then tried many different tips, tricks, and some personal deductive common sense based on device and battery usage to recreate scenarios people were having and then had others test the findings. Then took all that and distilled it in to a guide that have the best repair solution that covers as many (in this case all so far) scenarios and fixes them as I could.

Now, I continually get replies thanking me, defending my guide to some trolls that pop up when I am absent, and a forum moderator who also verified it works as stated for scenarios people find themselves in and stickied it. I don't claim this is magic and can fix EVERYTHING (like if you drop it in water or fry it with wrong charger/voltage this won't help), but it truly can fix issues where Android has in some way miscalculated the voltage of the battery and thus is affecting the discharge time in a negative fashion.
