"please read any comments as some are useful"
Before you start doing this make sure you have time on your hands.
Follow it step by step...
Read the entire set of steps and comments first.
Do not deviate.
If you are having issue's with it not charging fully. "70% to 90% and no further." then begin at step 7
If you have Xrecovery installed wipe battery stats first to reset the battery cache to the defaults.
This post will not talk about apps or any odd mods.
It's here to clear up on how to properly optimize the battery in your phone.
The battery has a cache file used to set the top and bottom battery level.
Today i am gona teach you how to set it correctly using nothing more than your phone and charger.
While doing this it will also properly "cycle" the cells.
This leads to the final part of my guide.
Damaged batteries.
If your life on the battery when using only airplane mode.
Is very bad.
Then you should be careful.
1. Check for any swelling or deformation on the battery.
2. Battery gets very warm while charging on standby in airplane mode.
If found Discontinue guide and replace with new battery.
And calibrate again from step 1.
-Enjoy
1. Charge your phone fully to 100%
2. Plug out your charger & switch off your phone.
3. Remove the battery and plug in the charger.
4. Re-insert your battery
This is sets the top end battery parameter to a higher state allowing for further charging.
Should read 88% now.
5. Keep a eye on your phone as it charges!!!
Remove the back plate and feel if it's getting hot "it should not be a issue"
6. Repeat steps 1 to 5
Repeat this no more than 2 to 5 times till the battery will not charge further
A few extra may be required...
The battery may get stuck at 70% to 99% "most of the time 88%"
The cells have now reached full potential
IF in the case that it keeps charging after the 4th time your battery is fully optimized Enjoy, Continue with step 7
7. Let your phone run down it's battery
Don't use the phone aggressively
Leave it till it switches itself off
Now it has marked the very lowest point of the cell in the cache
8. Don't leave the battery empty, begin charging as soon as possible.
If your phone does not switch on right away.. relax.
Just leave it on charge for about a hour "will switch itself on"
9. Repeat steps 7 and 8 a few times.
You will notice each time that the battery may charge just slightly bellow 100%
Getting closer to 100% each time
10.Soon it will read 100%
It has now marked the top charged point for the cells
If step 7&8 does not bring the battery to 100% use the battery calibration app from the market.
Don't rush.. take it calm and easy.
Enjoy your properly set, fully optimized battery.
If you are planning on flashing a new rom you can copy "data/system/batterystats.bin"
And copy it back once you are done flashing.
This way you don't lose the optimization.
The battery does have over current protection it should be just fine.
Still be careful.
This knowledge is based on direct experience building electronic projects for over 23years that require rechargeable cells and the nightmares i had with a bad x10 chipset..
REMEMBER THAT I'M NOT RESPONSIBLE IF YOUR PHONE BLOWS UP ETC.
:- final edit 2011/9/12 -:- 3:09PM
Added extra on damaged cells.
Found a few more mistakes and required details... edited.
Added a line for Xrecovery users. <<< removed this.. it's crap.
Thank you xcxa23 for showing me where the battery stats file is.
LET me MAKE this 100% CLEAR... wiping stats = nothing
This guide cycle's your battery, by correctly setting the upper and lower parameters of the cell.
[GUIDE] X10 Battery Calibration arent this the same? if you wanted to do it manually, u can go to data/sytem and delete the batterystats.bin file. but of cos u had to wait till 100% before u delete the file

Nope.. it does not matter.
This is not a hack or a trick.
It's simple li-ion battery science.
If it still has problems then your battery is already optimized and your problem is completely different.
This 7% in heavy usage or light usage or standby?

it's because u wiped battery stats on the low battery charge and didn't make a battery calibration. I had the same problem until the calibrating using another method (for me is easier, but this topic shows another way, which can probable be very effective )
Thx OP, although it was stated in another thread like noticed
Someone on XDA also done an Android app, Battery Calibration, easying the process of battery calibration/wiping.
I don't use it for calibration, just to get battery health in mV (even if you can grab it from Android System Info, Android Assistant, etc).
Still using the good ol' method of xrecovery
Yup, I said it. Nothing. Nada. Zip. Well, deleting the .bin file does do something...it resets the battery stats. Wanna know what else resets the stats?? Charging your phone to 100%. So, whatever benefit you saw from deleting the .bin was a placebo effect. Don't get me wrong, deleting it won't hurt anything. But it doesn't help anything either, and it certainly doesn't calibrate your battery. The only thing that file contains are stats, such as:
1. info about wakelocks
2. info about partial wakelocks
3. info about screen on time
4. info about screen brightness
I'm tempted to get into how lithium ion cells work, but that is a boring subject. I will say that li-ion cells don't have a memory to them, so there really isn't a "calibration" process. I will say that if you have piss poor battery life, you should consider the following:
1. An application/process that isn't allowing the phone to sleep correctly (keeping this general)
2. Any SamSprint firmware or derivative thereof
3. Knock it off with the overclocking. If you wanna screw with frequency tables and voltages, or let someone else do it and flash their kernel, be my guest. But don't ***** about your battery life if you do
4. YOUR BATTERY!!!!
Wanna know how I fixed the ****ty battery life on my girlfriend's Epic? I bought her a new battery I nice new shiny Epic Touch 4g battery with 20% more capacity and BAM, 2 days of battery life easily instead of 4-5 hours.
Seriously though, so many things affect not only battery life, but battery lifespan e.g. age (many users have had this phone for 1.5 years), # of charge/discharge cycles, excessive heat or cold (I bet a lot of people keep their phone in their pocket or a purse, huh?), etc. And while there may be quality control standards in the battery manufacturing process, not all batteries are equal and it's very possible that a battery was well below its stated capacity even when it was brand new.
Anyway, I'm tired and I need a coffee. I'm interested to hear others chime in and add to the discussion. Flame on! jk

Crap! This was supposed to go in general... Mods, please move
This is what I've been saying all along. You put a battery in. You charge it. End of story.
All these people wasting literally hours upon hours on "calibrating" their battery are tools who should not be members of a development forum.

Many people will argue that wiping battery stats is actually WORSE for battery life while using the same battery. After cycling perhaps. I think switching batteries requires a stat wipe though.

Wiping battery stats has NOTHING to do with battery 'life'. It does however effect time from a full charge if charged from the epic itself.
What the file that is removed does it tell android what the battery level is for logging and status info. When something changes like the battery strength (age) or life change from the rom/kernel/tweaks then you need to delete that file or else it will assume the older setup is used as a norm. Android uses the data to tell the battery to stop charging at a level of 95ish% and also to power down at 5ish%. If these values are incorrect the phone won't keep a charge as log or power off earlier.

But this is right... sometimes if you don't clear your battery stats your phone still thinks you have, for example, say 75%, when you really have something less, like 50%. Thus when you charge it, it will think its charging to 100 from 75 rather than from 50. Leaving you 25% less battery or whatever and your phone will seem like its dying faster. Only because you haven't "fully" charged the battery. So in some cases, calibrating the battery by removing the file is neccessary.

Battery stats do nothing... I never charge my battery. I swap out with charged batteries. You can NOT make your power on time longer with battery stats!!! I've proved that with swapper batteries versus charging and wiping stats... It's a myth only because there is a file which tracks status. That file is rewritten to and reset everytime I swap batteries.

This. The battery stats contain nothing about your battery percentage. Those who think that are misinformed.
I thought the percentage is directly related to the voltage left on the battery. So how could any stats affect that?

Look out! Here comes the Peanut Gallery! But seriously, my point was that most people don't stop and think for even a second that their battery might be the problem. If you have a 2 year old battery that you've put through the ringer and it you are getting ****ty battery life, you should quit being a cheap ass and buy a new battery. The Epic Touch battery is $18 on Amazon and a 20% increase in capacity. Kind of a no brainer. Unless you're a cheap ass. Or slow. Or you think that wiping a binary file will magically fix it. Or you're a cheap ass.
I am kind of amazed with what I am seeing, and am wondering if someone on XDA can help me understand this. So I was running CM7.x on my MT4G for over an year, and this past weekend I switched to CoreDroid because I wanted to try out Sense.
I had a bad feeling about the battery usage because the ROM was "heavier" than CM7.x in terms of UI, Graphics (of course because of Sense 3.5). I went ahead and installed the ROM anyways.
Within a couple of hours, I went from being fully charged to 5% battery....it was draining faster than anything I have seen before. I read CoreDroid release notes and they had mentioned about this severely fast battery drain.
Based on their recommendation, I fully charged the phone once battery level reached 5%. This time, my battery lasted about 17-18 hours, and again I fully charged it when it reached 5%.
Now after the second recharge, its been about 24 hours and I am at 97% battery. I didn't believe CoreDroid release notes that battery life will become better after couple of recharges; I thought it was a bunch of bull to get people to install their ROM.
I am glad to say I was wrong Can someone please explain this battery calibration deal to me?
Oh boy... This is a highly controversial topic. Here we go.
Basically there are people who swear by it and people who say it does nothing. That its all in your head.

Best link ever; most informative.
- I think everyone loves Dianne now.
- Someone has a flying car already ...
- In the middle of the most intellectual and technical discussion of battery usage that I have seen, someone asks what is the best facebook app - brilliant!
So...
1. Battery stats are calculated differently per phone and OS version.
2. Battery stats reporting is definitely not %100 accurate.
3. Battery percentage is calculated differently per phone and OS version.
4. Battery percentage reporting is definitely not %100 accurate.
5. On some phones, you can override battery charging limitations by 'bumping'.
6. 'Bumping' is not recommended as can shorten your battery life.
They actually did not cover the OP situation where you let that battery go below 5%, although I am always guilty of skim reading. Still, extremely informative and explains a lot of previously posted battery phenomena.

The drain-charge cycles is just a way to calibrate the battery- takes more time to "forget" the old stats, so people either use an app or manually delete the battery statistics so one can start accumulating fresh statistics.
After a few days you get your statistics right, from then on the battery indicator will be more or less accurate.
Battery drainage has nothing to do, really, with how many times you'll calibrate or drain/ charge or whatever. It has to do with how much you use screen on, Wifi, BT, gps, partial wakelocks, apps syncing etc. In other words- use your phone and be assured battery is going to drain. Leave it alone, let it sleep- battery will last a couple of days...

just to clarify, and sorry for butting in, but there is no such thing as "calibrating your battery"... this has been debunked by many people who understand android's Linux kernel and even an android engineer at Google.
the batterystats.bin file is simply that, a bin. it does nothing more than collect dumped statistics of what exactly has been using your battery, how long, how much power those processes used, etc. it has absolutely nothing to do with your phone's ability to display correct information about how much juice you have left - that function is within the Linux kernel which monitors, and controls power throughout the device.
ask yourself this... ever flashed a ROM with say 50% power left on a charge? what happens after your first boot? does your phone suddenly have no idea how much charge is left? no. it doesn't. because the new kernel you just flashed with your ROM is picking up right where you left off.
wiping battery stats is useless. period. it.does absolutely nothing to better battery life. that is fact. that is your phone. that is your Linux platform and straight truth in how it works.
and since it is stored in the data directory, every time you flash a ROM and wipe data, you are wiping the battery stats... so why do you boot up and do it again... I know... good question.

Yep, agree with your comments 100%. After reading the link posted by estallings15 earlier in this thread, the myth of battery calibration was busted
I agree with most that Battery Calibration is a joke, and doesn't mean anything. However, batteries in many devices (not just our Cell Phones) seem to benefit from proper discharge/full charge cycles. In fact, it's usually recommended in things like electric RC cars that you completely run down the battery as far as you can go (realistically of course!) prior to charging; also to prolong battery life. I always notice at least slightly longer use times if I don't always pop the thing on a charger at 75%. But go with what works for ya, and of course some roms DO drain faster than others. And less screen haha
I found a guide somewhere on the internet on the best way to calibrate battery stats on a rooted device when I had my old hero and I use it a lot to this day so I decided to share the best way to do it here. If there is in fact a thread about this already in our forums I apologize but I could not find one. So here it is.
Step 1.
First and foremost charge the phone to 100%(Even if it says 100% wait about 5 minutes or so just be sure.)
Step 2.
Once it is at 100% go into data/system (using root explorer) and delete the batterystats.bin file there.
Step 3.
Unplug the charger and reboot to recovery, wipe cache and dalvik cache and wipe battery stats once more while you're there just to make sure they're gone.
Step 4.
Power the phone down and plug it back in. Charge it to 100% while it's off (the battery bar can be deceiving so even once it shows it's full give it five more minutes or so to be sure) and then power up.
*As a side note, if you are using stock kernel, or a kernel without the 100% battery mod then your only going to be at 96%. Thanks to Glennkaonang for reminding me of this.
Once it is booted to the OS you should now see that the battery bar is at 100%. (please note that when it's going through the "Android is upgrading" thing it can take 1 or 2% off the battery if you have lots of apps)
Final step.
Wait for the phone to die completely (to where it shuts off on its own) and let it charge to 100% while the phone is off and power it back up. Do this step at least two or three times.
After that you should have a fully calibrated battery and have no more messed up battery reporting.
Photo of my average battery life just for fun.
Everybody enjoy! If this helped you please hit thanks!
*Thanks to whoever it was that wrote this up in the first place. If I knew who it was I would give proper thanks.

Unless my batt % reporting goes wonky between reboots, I don't ever wipe stats. It doesn't necessarily increase your battery life, but it does appear to fix incorrect reporting.

I didn't think it would improve battery life either but it does. Maybe not a HUGE amount but it definitely does help a little. Plus it will give you the correct percentage rather than showing 100% when it's really only 95%. Lol. Anyways, to each their own.

It's just cosmetic, actually it's still the same 96% as all other Android devices do.

That's pretty much what I was going to say. Lol. I need to add that to the OP.

This doesn't do anything other than fix incorrect battery logging, it DOES NOT increase battery life in any way.
Not even a tiny bit. Nada. Zip. Zero.
Dianne hackborne covered this on Google+ and said repeatedly that it doesn't extend battery life in the slightest. She would know as she wrote the code I believe.
Placebo effect in operation here. Plain and simple.
Thanks a bunch.

Why do you insist on bumping this? No new information has been uncovered, nothing has changed.
The only reason I can think of is that you are looking to stock up on thanks.
I did this before I even found this thread, save for I use a Battery Calibration app from the market instead of deleting the .bin file. (App does it for me.)
This was the result.
Word.
Great guide! I haven't saw a calibrating guide either. I think it should be sticky!

I wasn't trying to troll your stuff. I appreciate that somebody created this guide (albeit now proved to be ineffective/useless) as an informative resource for others. That being said, this information is easily found everywhere, especially with search.
Please understand, if everybody bumped a thread they created every few days because they thought it was useful, nothing new would ever show up on the first page of the forum. It would be the same threads appearing over and over.
I wasn't trying to offend you, I just think that bumping dying/dead threads is counter intuitive to growing this forum community.
Thank you.
It is in a sense misinformation though. It doesn't calibrate the battery, merely wipes androids battery usage statistics, which are only for reference to the user not the system.
Although included, the only pseudo calibration is charge fully, discharge fully then charge fully. This process wipes battery stats anyway.

I have never calibrated my battery and get almost exactly the same battery life as what you are getting. All this does is wipe the stats.

Just Flash It !!!
Wherever I charge my Note 3 fully, even if I leave it on for extra 30 mins, unplug charger and reboot the phone, phone comes on to 98%. Even when I charge full and just unplug, it drains to 98% on idle in 20 to 30 mins. Whenever it gets to 98% then it stops draining. I believe I need to recalibrate?
I have tried everything I can but to no avail! Every good re calibration app with super reviews! Still nothing! Even Manual recalibration and FULL WIPE (Including Internal SD), tried total drain to 0% and switched off itself too.
Need suggestions. Cheers!
the battery will charge to 100% then turn off and allow the device to go down to about 95% before recharging back up. It stops you from overcharging your battery and destroying it, there is no drama with your battery from what you describe mine does exactly the same thing on both devices I have had

I understand u very well, but it just seems off! Because going down to 98% without even 'touching' the phone, NO WAKELOCKS, nothing serious enough at least... And it wasn't always this way. Just started about a month ago or so. My S2, S3, and S4 never did like so... But thanks for your time bro!
Nothing to worry. It's all ok man.

Even mine does the same, not sure though why.

Thank you bhai! But, do you think it's MJ7 firmware? Battery is not as good as MI2, and earlier. And can you we flash MJ6 over MJ7? Since both have the new bootloader, it should work fine yes?
Mine does the same! 98% limit.
I get 10hrs usage before recharging again. :good:
Stop being so anal - . Battery will drop slightly, mine does it, as do many others in this thread. 100% to 98% is nothing. It's usually after 90% that you start to see the real battery life anyway.

Do you understand words have more than one meaning? - In this instance you "seem" to think that the term anal is used in a sexual context. Whether it's a miscomunication in language/Lost in translation or you are just too stupid/naive to realise.. I do not know. - So think before you start crying in a thread next time. A word you may say in your country may offend many here also -
-- As for the battery percentage question, I gave an answer for that, so stop being anal about it.
What you said is same as saying dont be an a**hole!! And second dont refer other people as being stupid/native just because you know 1 or 2 things!
About the battery % it isnt a problem. Its normal system fuction it happens to everyone including me. And I get 10hrs of use with single charge.
What didnt u understand, mr.Smart?!!

Calling someone anal does not constitute the same as saying someone as you put it "an a**hole!!" - I never called you stupid or "native" (Naive is what I said) I merely stated I didn't know if you were either of these you implied otherwise... I never claimed to know anything, So your point is moot. (Google it if you're stuck)
for the record ---
Noun
1.
anal personality - (psychoanalysis) a personality characterized by meticulous neatness and suspicion and reserve; said to be formed in early childhood by fixation during the anal stage of development (usually as a consequence of toilet training)

Now do me a favour and give up, Cause you're boring me.
-- Again with the battery situation, it's perfectly normal, It seems this subject has been hijacked by someone who has obviously got lost in translation and has disctracted the thread.
Stay away from Battery calibration Apps, they can play havoc with your phone also, at first they work but they always have a tendancy to mess up at some point.
Unless your battery is draining at a crazy speed I wouldn't worry too much. - You should be getting about 15-20 hours with an average of 3-4hrs screen time out of the devce with moderate use.
Sorry i mean stupid/naive not native.
Mate, there is no need for all these...
If im boring dont reply.
Next time try to explain without putting anyword to show or trying to make people feel stupid. This is my point.
We arent in english gLass and the thread is worldwide, just get to the point and move on.
Just that.
My battery is okay...I get 10hr of heavy use. 3g and bluetooth always on. My s3 had only 6hrs of heavy usage.
I dont complain of battery draining is normal for my usage.
Im also checking the wakelocks and batt consumption at night. Still in progress.
Sent from my SM-N900 using Tapatalk
So moving on, you get a solid 10 hours with heavy use currently? - how is your consumption at night? - mine drops about 5% over a period of about 7-8 hrs roughly.
I average around 25 hrs currently with moderate use and WiFi on all the time

My Note 3 also drops from 100% to 98% very quickly even with no use of the phone.It also seems to drop to the low 90% range very quickly but then it settles down and battery life is excellent.Surfing the web seems to use more power than watching videos.I lose about 3 to 4% overnight.
I noticed my battery discharge faster after upgrading to latest MJ7 firmware. Before the update, my battery lasted very long. Hopefully samsung release a small update fix on this battery bug.
