Yet another thread update incoming, sorry for disappearing for a bit got me a Nexus 7 and was playing with and learning it and JB some without distraction...

Next update will be posted hopefully today and I will be doing some great info about Beats usage! I also found a certain installer of Beats with an actual control panel!:

Of course I will upload to my domain so it's always around and link it when I do the update as well.

Just got to get to a computer and type it all up nicely in to the I believe second post at beginning of this thread [will be first question under the FAQ heading I have along with all the other non calibration info I already posted as well as a standalone post as a new reply to thread so you can direct link just the post]!

Beats has made the fidelity ( sound quality not just louder volume) of even my phone speaker, man is my equalizer if choose and is system wide (replaces things like DSP Manager) and is now what I swear by.

Actually, Android accounts for this when it says 0 and shuts down the physical battery itself is not truly fully discharged (if it were it would not work period unless you have a very special trickle charger to recover it or buy a new one). Now if the phone hangs on shutdown or restart the device can given enough time absolutely drain the battery past the safe limit and make it a paper weight. Also lithium ion batteries will lose life and performance over time (and number of charge cycles) no matter what you do (lithium ion batteries shelf life from production on is roughly 3-5 years even if just left on a shelf (though the loss of full charge over time from not being charged will prolly get you if you don't charge them from time to time and just leave in a shelf before their actual usable life does (and is partially why when you get a new device or battery it has a usable charge of some sort when you turn it on before first charge).

This information (expected life and expected maximum number of charge cycles can almost always be found in the instruction manual or warning labels you get with devices and batteries (if you bother to read that sort of thing)).

Again:

I never, never post information formally without fully using with myself and others as testers and know what is all entailed I do days, weeks, and months worth of research I don't just post info on a whim and doubt a moderator would stickie a thread that have info that would more often than not cause your device damage.

Along with that, I am known to over explain things and post warnings and all where appropriate (and sometimes even moreso than I prolly need to). All in an attempt to help you avoid any damage as I know I can't easily afford to replace my devices. I could not live with myself if I caused others to have no phone or other device, along with, the associated pain and expense of replacement that causes (can't account for silliness; I won't take responsibility if you miss a step, misunderstood something, or otherwise caused the problem yourself through some form of negligence). I am ALWAYS around to PM and/or reply to my posts (PMs ensure you get my attention faster usually) for you to get further help and clarification BEFORE you attempt things. I will still try to help anyone to the best of my abilities (and even refer you to other people and places if I feel they can better assist you) with problem, it is easier to ensure no problems by fully understanding something before you attempt it.

Lastly, obviously no one can guarantee something wrong won't happen. This is due to no one can 100% account for your personal usage, your personal devices exact hardware condition, software setup, experience level, etc. Anyone who does guarantee something will work without the possibility of problems should not.

I do appreciate your concern as it is good to be wary, but hopefully this helps you feel better that I exhaustively research and test EVERYTHING (OR POST WARNINGS IF I AM IN "BETA" STAGES OF ANY RESEARCH ON WHAT I POST)

Update is on its way, It is just taking longer to get some of the information and formatting the way I like it.

I am currently debating on changing the formatting of the presentation of the information. I am thinking of using spoilers (this would collapse each answer under the associated question and expand to give you the text when you click a button).

I definitely will do it to the Q&A, it's just when I do that I will read the text and have lots of changes (grammar, structure, screenshots, etc.), so it will alone end up taking a good amount of time.

I am interested in what others think about something like that for the instructions themselves? Should I restructure it more in to sections and leave basic steps with full info collapsed kinda below each? Should I leave them as they are? No matter what, I still will end up going through and enhancing those, eventually.

Thanks for any replies, and patience. I am trying to not only bring new information, but working to continually enhance everything in the OP and related posts.

I would appreciate it if the trolls would stop. This same question/statement has been made a dispelled many times at nauseam by myself as well as others (just search the thread it isn't long to even view all posts).

If you aren't a troll you will have to excuse me, but your name and whole 6 post count lead me to believe otherwise. Why is it every user who posts this same post has the minimum 5 posts and name obviously meant to inflame on its own.

Really it gets old after the first time and gets in the way of real questions, why don't you study up on topics that affect you and as you solve them make worthwhile contributions that could help others rather than try to spark childish arguments?

How much did you learn about battery callibration yourself?

I usually don't care if someones are wiping batterystat file all day long but when one is saying that's the "secret google way" dispite multiple references to the one of the Google engineer's blog and such post become sticky ... wow, so much for worthwhile contribution... perhaps only to conspiracy theory :) .

I had a nice discussion with author of BatteryCalibration app way before that famous blog addressed the batterystat wiping thingy... After looking at android source code I asked why author is wiping that file - I am not kidding - the answer was "because someone said it somewhere in a forum"...

He has no idea about fuel gauge chip which provide SOC of battery to OS and it's hardware solution does not know/care about no batterystats file at all.

I think you need to learn a bit more and revisit your OP.
[T-Mobile Samsung Galaxy S II SGH-T989] RealPariah:
By reading the guide FULLY and following the steps (look at very first post of thread). Please remember this is not magic, and can only help if your battery levels are being miscalculated to begin with. If your battery is working 100% this guide will not add anymore life to your battery then it is already capable of.

[T-Mobile Samsung Galaxy S II SGH-T989] Vlad_z:
I'm not saying you are posting lies. I can see you genuinely believe in your tips and like to test it yourself. I respect people who want to learn something new so let me be more constructive.

First, Android usually (as far as I saw in many kernels) does not write back to FG chip - only read state of charge (SOC) about once in couple min. And that the percentage of battery charge you see everywhere in UI. No voltage or any other merits involved.

Once chip reports SOC=0 (even if battery voltage is way above 3.5V) - Android would shutdown itself. That's the sign of FG chip miscalibration.

Question how internal data inside that chip got corrupted - I have no reliable explanation. I've got this situation only couple times and not during flash of new ROM... just out of blue...

But I have 100% explanation of why your calibration is working...

Only two easy things which will recalibrate fuel gauge chip (according to chip documentation).

1) Chip will recalibrate itself with time. No need for deep cycles - just reasonable charge/discharge with pauses in between.

2) Chip will be forced to use it's "average" SOC curves when it sees new battery installed. Means, physically disconnect battery and let capacitors get completely discharged.

So, that's it. This is how fuel gauge chip got calibrated. It's that simple.

Yay, I have finally found a day where I have a good amount of time to work on this thread! I have already begun cleaning up the first 2 posts. I am first going through and using the hide tag to reduce the overall size of the loaded thread [not sure how mobile clients will read the tags yet so if using a mobile client you may still see the entire text and not the show content sections.

I am also going through and cleaning up the language and updating to include information for JB and also finally add NEW information I have collected as well.

As I said soo far first 2 posts are in generally much better shape and are an example of how I will be cleaning up each of the Question and Answer pieces and other parts of the other posts.

Can't wipe battery stats

I am trying to calibrate my battery, and can't find an Advanced Option under the Recovery Mode menu.

Is there any other way to wipe battery stats?

Thank you.
[T-Mobile Samsung Galaxy S II SGH-T989] kpavl01:
I did this:

> Charge phone to 100%

-> Restart phone [to be sure it isn't off by some amount (if phone off just unplug AC adapter for 30 secs and plug back in)]

-> Wait 20 min after you are sure it is 100% (phone should stay plugged in)

-> Boot in to recovery

-> wipe battery stats (advanced)

-> Get ready to pull battery and unplug phone and do so after the screen goes black after tapping restart device (pull AC adaptor first)

-> Wait 30 seconds and replace battery

-> Allow phone to boot

-> run through ENTIRE CHARGE (COMPLETELY DISCHARGE) the battery (whether normal usage or looped media files whatever you have time for)

-> restart phone to be sure it is totally dead

-> Charge fully one more time

But idk if my battery completely discharged, it was 0 % and when i turned my phone off it would boot and then die, but it will always boot first. So I turned it off and put it to charger and than turn it on and now it says 25% full.

What's up with that?

Right, didn't say this magically gives you extended battery life, only that our helps correct when the battery is not being handled correctly by android and doing this only corrects the problem giving you back the most battery life the battery you calibrate is using.

Also bad idea to do to many batteries with android it expects only one and generates statistics based on that. You may not notice right away but over time this can mess with android and is a perfect example of when your would use this (in that after swapping batteries numerous times you notice that the battery is not lasting as long as it used to before swap and then you calibrate to address that :) )

Did you know batteries are organized in to cells? These were different than a cellular radio modem (similar in a broad sense as the area the radio tower covers is a cell in the overall makeup of the body of radio coverage your phone company provides and also provides safety in that if one goes down it doesn't take the whole network with it and why it's called cellular it's not other devices it refers to your providers network which works in independent cells that connect together to create the network your phone connects to). Batteries are also segregated in to cells so if part of it is damaged it is limited to that cell of the battery and doesn't affect the the rest of the battery that is good?

To connect a variety of devices together with no central server or control point is actually refered to as a mesh network.

Depends, maybe you have an app like a live wallpaper that could be stopping your phone from entering sleep mode. Apps that constantly sync and are poorly coded to handle it correctly (I am looking at you Facebook) that are causing your battery to drain faster than you expect, but there is no issues with how your phone is currently handling the battery.

You can buy better battery stats on the market and it gives awesome and detailed info on how your phone is using the battery, what apps are requesting wakelocks (keeping your battery awake when you aren't using it), and is an awesome help.

[T-Mobile Samsung Galaxy S II SGH-T989] RealPariah:
Android is incorrectly stating your battery is at 0% and trying to shutdown to prevent it from discharging too far (which could kill the battery potentially for good so it is not usable).

These cases usually you just keep turning it on until it only vibrated. If it goes in to Android and then Android says shutting down, keep turning it on until it can't do that anymore. You will reach a point it can only vibrate then die without showing anything on the screen.

I've got a weird battery situation going on. I bought an extra battery and external charger. Now my phone will no longer charge my battery for more than a few seconds. The external charger will charge them to 100%. I'm guessing the charger burned out a safety feature in the battery. The POS said it had overcharge protection. Any other ideas? Thanks.
[T-Mobile Samsung Galaxy S II SGH-T989] jurassic512:
Charge the battery to 100% in your external charger, then put the battery in your phone and boot to recovery. If its still at 100%, wipe battery stats, and reboot. If no, connect your charger to your phone and see if it will continue to charge to 100%, then wipe battery stats.

Been having a battery issue for a while now and I am wondering if this guide would help me or if anything else I could do.

Basically my phone was left with a game running (forgot it on while i was at an appointment) the phone drained down and shutdown automatically. It was fairly hot too. Since then I can't charge the battery more than 89-90%. I thought my battery was damaged so I bought a new one, same thing. So I figured it is the phone. But I am not sure what should be done.

I might try this guide to "re calibrate" my battery.

If anyone has a better idea, let me know.
