1. Root your device and install Root Explorer.
2. Use your phone until the phone switches itself off (battery empty)
3. Switch on once more to make sure battery really is 0% (it will then immediately switch off once more)
4. Now, keep switched off (!), plug in charger & leave in charging until 100%
5. When battery is full, switch the phone on, unplug & check if the batter immediately drops 1 or 2 %
6. If battery immediately drops, plug in charger once more (while running phone) & let it charge completely
7. Once charging to 100% is done, don't plug off your charger, open your root explorer, at the top just click mount R/O, then it will set as mounted as R/O.
8.Ok, now open the 'Data' folder.
9.In the 'Data' folder, keep scrolling at the bottom and you will find 'System' Folder.
10.Open the 'System' folder and find 'batterystats.bin'.
11.Now you have to delete the 'batterystats.bin'. How to delete it?
12.Tap the 'batterystats.bin' and it will show the file option, select 'delete'.
13.Once it done, quick the root explorer and use the phone as usual until it switches itself off (battery empty).
14.Please don't charge your phone if the battery are not completely empty.
15.Charge your phone while running phone as usual until it shows 100% battery.
16.make sure that during discharging,don't reboot your phone or the system will create a new batterystats.bin file or if already made, it will get corrupted and you will have to start again from first step
17.Done this in 4 or 5 cycle, i mean the step 15 until step 18.
18.Now enjoy the 'long life' Samsung Battery Life!!

Note: these methods are not permanent and your battery stats may again get messed up any day, then you should repeat the method from first step.

You may try this a few battery tips here.

Clearing battery stats is pointless. Its just the placebo effect hard at work. Your phone doesn't stay charged any longer if you do this

To reset battery stats just use battery calibration app once calibrated dischrge cmpltly n then chrge until 100% without any break dats enough;-)

Sorry about recall an old thread, but I think is important to say that 4-6 deep discharge/charge cycles are recomend for new batteries by all manufacters. Normally people tend to bypass this procedure leading to use of batteries not completly "formed", thus lack of battery duration.

This process is not that recomended on old batteries as lion batteries don't like deep discharges.

Pretty sure this is a myth.

Batteries are pure chemistry... This process is valid for every battery known to man. It's not a myth.

Its more for the battery meter to not be off. Also; Motorolas dont like to turn on when they think the battery is dead and needs to charge... so.. bad battery stats can be a big deal.

Wiping battery stats in no, way, shape, or form affects battery indication. Please do some fact-checking regarding the subject matter at hand rather than perpetuating gross misinformation. The notion that wiping battery stats does anything even remotely useful was clearly and concisely debunked long ago.

The only actual valid posts in this thread have been from mr_clean5953, WastedJoker, and zelendel.The OP itself is riddled with misinformation and following the piss-poor advice given therein will shorten your battry's life.

The same holds true for the advice for 4-6 deep discharge cycles prior to first use. It is totally unnecessary and contrary to what was stated, is not recommended by manufacturers of lithium-based batteries. The individual posting that may have been confused by the fact that it is a recommended practice for nickel-based batteries. Li-ion and lithium polymer batteries see no benefit from "priming" prior to first use. The singular effect of following that misguided advice is a shortened serviceable life of the battery.

I would not recommend to do this extensive charge and deep discharge you will destroy your Li-Ion battery.
This is translated by google from the german wikipedia (de.wikipedia.org/wiki/Lithium-Ionen-Akkumulator)
Discharge
The voltage of the Li-ion battery during discharge decreases initially rather quickly reached by the charge voltage to the rated voltage (about 3.6 to 3.7 V) from, but then decreases during a long period of little further. Only shortly before the complete discharge, the cell voltage begins to fall sharply [26] The discharge voltage, depending on the cell type to 2.5V,. These must not be exceeded, otherwise the cell is destroyed by irreversible chemical processes. But many electronic devices switch at much higher voltages, such as 3.0V from.

It is recommended that Li-Ion batteries charge "flat" to (un-), since their lifespan extended way. When a Li-ion rechargeable battery is always discharged from 100% charge to 0% before charging it again, he reached only the minimum number of cycles. Better yet, depending on type, applicable for example, 70% DOD is. This means that the battery pack is at 30% capacity when it is reloaded. Some manufacturers give the cycle life as a function of discharge (engl. depth of discharge DOD) at [27].

In general, high discharge both reduce the rated capacity of a battery, because thanks to the higher voltage drop across the internal resistance of the discharge voltage is reached earlier, as well as reduce the number of cycles due to the higher mechanical and thermal stress. In previous releases is still at an optimum discharge current of 0.2 C (ie a discharge amounting to one-fifth of the nominal value of the rated capacity in Ah) pointed out. With a battery with a capacity of 5 Ah, this would be 1 A. [28]

so the best is just fully charge your phone leave it connected to the charger and delete the battery.bin and reboot

battery still at 0%

how am i gonna do this if my battery % is only 0?even though i chrge long period of time.this happens after i calibrate my battery..im using xperia sola.pls help me.

hi. did you find any solution to your problem? after I rooted my xperia neo with gingerbreak, my battery went to 0% and cannot be charged more in my phone. I was able to charge it outside of phone using some universal charger, but anyway in the phone it shows 0% and phone cannot be used without charger connected. thanks for any hint!!

I know this is an older thread, but I still believe that wiping the batt stat ALWAYS made my phone last longer! I would EASILY get 24 hours battery life after wiping and putting new rom on. After a few weeks or better, my batt life would go down to just a couple of hours!! I would use the Wipe Batt Stats in CWM and, VOILA! Back to 24 hours!! I don't understand why anyone could say that it doesn't do anything! Now that CWM took it out, I have to do it manually! I do it about every 3 to 4 weeks and I'm back to 24 hours batt life! Would someone that knows more than I please explain to me why it is a so called myth when it works perfectly for me? Am I just in another world or what? I just don't understand!

Placebo and logical fallacy. Those are the only reasons why you perceive it to have any effect.

Google's senior Android framework engineer, the individual who is repainted for much of the coding of the operating system and knows more about this than any other, had clearly and concisely debunked the myth of wiping battery stats. The statement that wiping battery stats will affect battery life has the exact same truth value as the statement that our moon is made of green cheese.

There is absolutely nothing contained in the file that you are wiping that is pertinent to battery life or indication. The one and only thing you are wiping is information pertaining to which apps held wakelocks and for how long.

If you want to read up on the subject, you can check out www.batteryuniversity.com and the Google Plus page of Dianne Hackborn.

nice info. Well now that's solved my question is, what the heck is the batterystats.bin for then?
 
No battery_stat from day one

This is a good question as I have an issue with my phone that maybe the result of bad deving on the side of the vendor. My phone does not have a battery_stat.bin file ANYWHERE. And since day one the OS or any other app can keep a good status or stat of the battery. Now does anyone know how I can force the OS 4.2.2 to create a battery_stat.bin file? Thanks

    This method is EXTREMELY dangerous, especially if you keep repeating it. This method will damage your battery and you will make it even worse than at the beggining.

    Use this method instead:

    1. Root your device;
    2. Download "Battery Calibration" app from Google Play;
    3. Download "ES File Explorer File Manager" app too from Google Play;
    4. Charge your device to full;
    5. Open "Battery Calibration" app and use premium option to calibrate ( You will have to watch an ad );
    6. Wait for it to calibrate and then open ES File Explorer File Manager;
    7. Press a button at the top left corner of the app;
    8. Find "Root Explorer" and "Show Hidden Files" features and enable them ( At Root Explorer, if it asks you to Allow or Deny the permission, allow it );
    9. Press a button next to the Home button in the program. Some folders should show up;
    10. Press Slash above the folders and search for "batterystats.bin".
    11. Delete the file and restart your device.

    This is a method that can't damage your battery.
