[T-Mobile Samsung Galaxy S II SGH-T989] RealPariah:
I am sorry I misread you, and sorry you got lost in the mix there., thank you, but you can only lead a horse to water I guess. I just love how he says research and then says that cache helps save you from bad shutdowns when in fact cache is set aside fast access memory [usually a chip on the device or could be provisioned RAM] and that is what causes the problems on bad shutdowns [since it is in a form of memory dependent on power an you lose power that data is lost and how to try to mitigate that on power loss or bad shutdowns is half the battle. I think he was talking about the journaling found in the EXT file systems I think which is supposed to help re-create corrupted data if it happens, but as with everything computer nothing is ever 100% in practice, and is why you have need for error checking with things like e2fsck.

Also, I hope he realizes Google ASSUMES THE FOLLOWING CASE WITH ALL SUBSCRIBERS When dealing with anything: You buy your Android Device, You turn it on, you use it (maybe with some accessories like headset and bluetooth), and you never change anything the OS, the Battery, anything inside the case. They enjoy modders and developers, BUT they always call anything modified [EVEN EXTENDED BATTERIES] outside the normal and therefore outside of warranty and outside of the scope of any support they offer.

I do my best volunteering my time giving information learned from countless hours of love poured in to a craft that I love, working on a MULTITUDE of devices [I have co-workers, neighbors, and even sometimes strangers approach me and have me help them do any number of things]

FOR INSTANCE THIS METHOD OF CALIBRATION was thought of, sorted out and gathered AFTER my boss had an issue with his phone lasting like 6 hours on a charge and he wondered why when using 3 different batteries the phone would behave differently even though they were all the same make and size. I then went out and researched why that could be and gathered information and learned what was happening, was able to re-create it and then I fixed it. That was back in Android 1.5 LoL. Now when I got the S2 and had the same things happening several years later I researched that it was still an issue and went about fine tuning a method for fixing it best on the T989. Since initially learning how to do this and when and why I have helped COUNTLESS users who always complain their batteries die too quickly and who have never rooted, modified their phones or otherwise knew they could and when I went about getting custom recoveries and running variations of this method they all came back the next day or several days later and profusely thank me that they magically gained anywhere from an extra hour to 6. So I have to laugh when folks who read the first couple paid for results and quote the theory written in text books that I have already found through further research and practical use while not intentionally wrong did not take in to account certain things [be that apps can freeze a phone to the point you pull the battery or that a phone never loses power in such a way to cause data loss is just speaking in absolutes which is always an absurd thing in the technological realm.
