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.
Hi.
I recently purchased a new battery since the old one is kind of broken.
However it didn't really increase battery life at all. In fact it now shuts down at 35%.
How do I make sure it actually makes use of the whole new battery?

Yes it is.
You must calibrate the battery.
To do it you must be rooted.
Advanced method;
Use a root explorer and go to /data/system. Delete "batterystats.bin" file . Then drain all the battery and charge it while phone is off and unplug the cable whem it says full.. Thats all.
Also there is much easier way to do it if you want. Download battery calibrater app from google play and use it! BUT in any of these methods,you must be rooted.
After doing this it must be normal.Also flashing stock rom and non rooted musn't be problem

adytum is right. The phone doesn't need to be rooted. Rooted you can destroy the phones battery statistic file at once but you don't need to. Android permanently learns about your battery (high / low voltage) when charging and discharging.
Have some patience, give your new battery some full charges / discharges and everything should be OK.
I'm going to start working on this then.
Thanks alot !
I was already afraid my whole SGS was broken.

Difficult question - doing big researches will lead to different answers.
The only thing for sure is that completely drained or somehow even completely full batteries will age faster because of electrochemical reactions. Completely drained is worst case, of course.
A common recommendation of the industrie is to store an unused battery charged at about 60-70% and then put it away in some cold storage. That is because even LiIo-batteries suffer self-discharge of about 5-10% per month so it could avoid both stressfull states (0% / 100%) for a long time.
Your phone will never physically drain the battery completely, but will shut down itself before damage is done (don't know if this limit/border could be tweaked, but with StockROMs you should be save). Although it might say 0% there is still some energy left. So it wouldn't hurt to "drain your battery completely" down to 0% a few time if you don't forget to charge it afterwards.
As Android stores the min and max voltage of your battery your really should do complete cycles if you want Android to get your battery statistics right. You even have to do this if you killed Androids battery file on a rooted phone.
Much more damage will be done by keeping the battery at high temperatures, e.g. playing heavy games
I've been doing what has been suggested, however my phone keeps turning off between 30-40%.
Is there any way to solve this?

If you already have a rooted phone and no patience (no experience myself on this matter with ICS or JB), then you could use app "BatteryCalibration" to remove batterystats.bin file as was said in one of the initial postings.
if u use cm10 you can also enter cwm and whipe battery stats, i think under advanced

For the first charge I let it run down to 5%, then after that I just do whatevers needed.
Its personal pref tho, some people will say you need to, others say it's not necessary.

Just don't let it run out. The first few times you use the phone, you should do a full cycle charge.
Let it run down to 5% or less and then charge it to 100%

when they say "fully run down", don't they mean run down till literally zero? on advanced phones like ours, you'll never get a chance to fully run down the phone because it'll shut down way before that happens, unless you keep it turned off and sitting there for a couple of weeks, which should almost never happen to anyone.
so i think you can run down the phone, at least till it turns off by itself, and then charge again till full.
The battery life is beyond words,I never get to drain it more than 30% ,I just charge by bed time,dnt bother about battery calibration unless u change ur rom

Hi, I've bought a nexus 4 about a month ago. I works great and the battery life is good enought but i notice that sometimes I connect the charger (when the battery is 40% full for example) and a few minutes later it says it is 100%.
Ofcourse it's not and some minutes later it drops. If I reboot the phone it shows the correct percentaje, but I happens very often.
Somebody has the same issue?
I didn't try to wipe the battery stats because I didnt install a custom recovery. Is there any way to fix it without flashing it?

Most N4's have some quirky battery stat behaviour. You'll have to learn to live with it, wiping battery stats, or reflashing the stock images, or an alternative ROM, won't do anything to address this.

It's the first thing I noticed about the phone. I've only charged from 0 to 100 in a second once though when I first got the phone, aside from that just the occasional lazy updating of the actual percentage. Stressing the phone a bit tends to help it "catch up" to where it should be.
Edit: you know, it's good OCD therapy, it may help you get past your OCD if you have it.
If you don't have OCD, you certainly will now...

Yes, the same happened to me, the issue is that sometimes I lost track of when it plug it to the charger and after use it the battery drains. It is very annoying.
I will try to charge from 0 to 100 a few times to si if the stats sync with the real battery state...
Thank
I'm getting pretty consistent reading far as 0% - 100% goes (course I drained the battery down to zero twice and charged back up).
What I'm finding that seems rather weird is glitchy mV reading with battery monitor widget pro. It does decrease as the battery decreases as expected, what's unexpected is all the lil spikes upward in it's value over time, like every few mins it'll jump up like from 3995mv to 4040mv or similar jumps as if the widget can't get an accurate reading of the battery's mV level. So it look weird because the only time you would see the mV rising, is if you're charging it.
And I know someone else on this forums with a Nexus 4 that's actually showing positive mA values when he's not even plugged into a charger.
But as far as % reading goes, seems pretty accurate now, just the readings I'm getting from battery monitor widget had me concerned that the battery was bad on my less than a week old Nexus 4. My Nexus 7's history/stats look rock-stable by comparison, kind of wondering if it's an LG thing.

Well Google support definitely knows this is a big problem. After I explained the exact same issues I was having with the battery indicator being wrong they offered a in warranty replacement right away with no trouble shooting what so ever. Problem was they wanted to authorize my debit card for the full price of a phone plus shipping until they received mine back. Unfortunately I didn't have 230 bucks that I could just have tied up in authorization limbo for 2 weeks. So they transferred me to LG support because they have a return policy where they let you ship the phone back first. LG at first tried to say they only do paid repairs on Nexus 4's and that google is responsible for warranty's, but a little arguing about manufacturer warranty laws in the US and threatening to file a complaint with the FCC they agreed to replace the phone under LG warranty. Again they didn't do any troubleshooting at all. Upon explaining the problem they went right into replacement phone. This leads me to believe there is no easy fix or software problem they can update, but rather a hardware problem.

I have exactly this behavior all of a sudden the last 2 weeks.
I have worse issues....
We had the screen/digitizer replaced after my wife dropped the phone.
The phone now has some issues. It will charge, and operate ok until the battery reaches about 80%.
Then the touch will go crazy, and the phone will turn off.
Upon rebooting, the battery is suddenly at 0%.
I purchased a new battery and installed it. It charged to 100% the first time and the phone lasted for a while.
Then after that it refused to charge at all. Didn't matter how many times I did the power + volume up trick.
I put the original battery back in, and it charges, but of course dies after it reaches 80%.
Same here. Problems after screen replacement month or two ago, not sure that related. Battery went bad. After replacement with a new one (original not chinies) not stable: shows 100% charge then turn off on in 10 min, after powered on again shows 65 % and after 10 minutes plugged in 100% charged.
Driving me crazy... Fully wiped, factory reset all the same. Rooted and wiped battery stats not helped. Very frustrating if some one can suggest one else can be done...
The phone is just fine, powerfull . no reasons to replace
I also developed my battery issue about a month after replacing the screen and digitizer. I'm going to take it apart and clean the connectors and see if that helps, because I'm so annoyed I'm about to buy a new phone.
My guess is that the battery was damaged during the screen/digitizer replacing process. It happened to me recently. No biggie 24 € for a new LG original battery seems pretty cheap and the problem was solved. But why are nowdays batteries somewhat soft??

I need some suggestions on how to calibrate the battery on my n4. It got miscalibrated when I did the update 4.2 to 4.3 and I haven't been able to calibrate it since then, a week ago.
I tried using battery calibration from the store but it didn't work, I tried charging the phone from 0 to 100 and it didn't work.
I remember I had the same problem 2 years ago with my Atrix and I solved it by wiping the battery stats from recovery, but now twrp and Cwm removed this feature and I don't know how to solve my problem.
Maybe it would help flashing all back to stock with the toolkit?
If you have any suggestions I'd really appreciate it.

Just the answer I didn't expected, and frankly a pretty useless answer, everybody knows that battery calibration doesn't improve battery life.
But I have other problems, like I turn off my device at 80% and when I turn it on it's at 77%. Do you think that's normal?

Just the answer I didn't expected, and frankly a pretty useless answer, everybody knows that battery calibration doesn't improve battery life.

Either faulty battery or do the following:
1.Completley discharge N4
2.Charge fully(+2 hours after hitting 100&) WITHOUT disconnecting from the charger.
3.Repeat for better results.

To be honest, I don't know.
But if I would be you I would just let it charge while it's off(So the big ass white battery icon).
Let me know if you got your battery sorted after the method I posted!

You mean off as in all the way off? If so, then that ~3% is being used when the phone boots.

I've had many phones, and none of them lost charge during the boot, at least not that many. I think that's the clear sign of battery miscalibration, I've had this problem before with another phone. Besides that, I've had a strange behaviour of the battery, for example I saw it lose 4% in 1 second, from 66 to 62 in a blink of an eye.

It's not that it's losing charge quickly, it's just the OS (or the hardware itself) doesn't always do the best job of reading it. There's not much you can do about that, and it's really not an issue unless you make it so by staring at your battery level all day.

Hi,
I'm having a similar issue. Phone rebooting to weird battery levels (not the %age it shutdown at).
Phone shutting down at 31% battery and rebooting to 0%.
I tried charging only to 100% yesterday with the phone ON.
Do I have to charge it even after it's charged to 100%?

I tried charging through the night and then discharging it completely and charging it completely again. I also tried deleting the batterystats file (even though I know it doesn't do anything)
So what do you suggest I should do? Get the phone replaced or get the battery changed?
I live in India and the phone is from Canada, so replacing the phone will take some time but I can get the battery replaced for around $20
Also my nexus is also showing +ve mA values while it's not charging, and the values are absolutely crazy, +268, +168, +1171 (in batter monitor widget)
Please tell me what I should do.

Before you replace the battery try to disconnect the battery's flex cable and reconnect it [after you charge to device to 100% and turn it off of course] check if its 'reset' the battery.
