Would u tell when to unplug charger after which step
And should to remove battery stats from recoveryas well as through that app????
Charge your phone to 100%, reboot into recovery remove your charger than wipe battery-stat. Reboot. Use your phone as regular use and let it die (completely to 0%) of battery with no charging in between. After that charge your phone to 100% at a stretch without any break like at night from 0% to 100% without break.

Calibration of Li-Ion batteries is nonsense. You can do any ritual and accompany it by a pole dance when the moon is full and it will have about the same effect like these "calibrations" and snake oil utilities that claim to perform such things.
These batteries degrade by heat. If you still insist, simply let it discharge until the phone turns off, charge to 100%, wipe the stats, repeat once more. Done. No utilities needed.

Battery Drain
I've been thinking about this the other day that the battery calibration app & wiping battery stats in recovery were just the same.
I just had the weirdest battery drain after I uninstalled the battery calibration app last night. I had around 80% battery before I slept & had almost 9 hours of sleep. When I woke up, I only had 35% battery??!! I'm using Devoid Franco plus his kernel & the phone was just idle as far as I know.
My fully charged battery lasted for a day & a half prior to this shocking battery drain.
Has anyone had a similar experience?

You've probably heard about this before, its simple:
1. Charge your phone to 100%!!
2. Boot into recovery
3. Scroll to Advanced > wipe battery stats
And there you go!! I'm running xboarders quicksense 1.5.1 and now it has tremendous battery life.
I originally saw this method in mikes android revolution Rom post so thanks to him!

I've read alot and tried many methods in the past, and one thing I am conviced is that you don't really have to drain your battery completely before cycling. The dev of 'Battery Doctor' app says you need to go below 20%. I can acheive pretty much the same effect if I start from just below 50%.
The key is to keep the charger plugged in after you get the green light. 20min is probablly right, although I tend to keep it longer because I usually go to sleep when I cycle batteries.
over charging lithium ions is not a good idea...also you do not need to cycle lithium ion batteries as they contain no memory as the old ni-metal hydrdie and ni-cd. batteries..
.infact is is advised to charge you batter often and keep electrons moving in your lith ion battery as oposed to ni-cd which is better to let it fully charge and fully discharge.
Do not over charge or fully discharge a lithium ion battery...infact the high voltage stresses the battery further and shortens its life. also do not discharge you battery fully as this is also not good for it...with lithium ions it is good to charge as often as possible, to prevent erosion inside the battery...while doing this you must not use the device...so even if you charge it for 10 minutes its a good thing for the battery. do not use the phone while charging as this confuses the battery.
here's a good article, that explains everything completely http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
From what I have read so far, wiping battery stats simply erases the information in the battery usage screen. I don't see it having any benefits to how long the battery lasts even in my previous attempts to increase battery life.

While I believe the information you posted is true, I think it may mislead some people here.
1. when you wipe the battery stats, you still need to do the cycling. Otherwise, your new stats will be off.
2. 'plugged in' doesn't mean 'constantly charging'. The IC chip on our phone is supposed to do what you are recommending we should do; charge to close to full, drain some, then charge to close to full. I say 'supposed to' because I only read about it somewhere.

You're righ that wiping battery stats won't improve your battery hardware-wise. But if done properly, wiping stats and cycling should re-align your phone's knowledge of the real battery capacity. If you have 100% at one time and 50% just an hour later, you know either your battery is bad, or your stats is off.

Two days!? That's awsome. My Amaze only lasts 15+ hours with all the battery saving tricks applied. Well, I play games and music so I thought it's normal. Which rom did you have running on your Desire? Oh, never mind. I thought Desire was G2, which my daughter uses.

A properly designed battery charger (like the one in the phone) will not overcharge the battery. These chargers have circuitry to prevent overheat, and as the phone gets close to maximum charge, they slow down and then stop the current flow. They don't want exploding batteries!
EDIT: I do worry, however, that the phone is designed for the stock battery at 1.8v, and might overcharge a replacement battery (mine are all 3.7v). I have read of some people that had overheated aftermarket batteries when charged in the phone. I use my external charger for the spare batteries.

You don't need CWM recovery. You don't really have to be rooted, either. If you know how to temp-root, you can wipe the battery stats using adb shell or terminal emulator.
The file is located at /data/system/batterystats.bin. You can remove it by:
Code:
adb shell
rm /data/system/batterystats.bin
Don't forget to 'su' if you're using terminal emulator.
In my experience, the best time to wipe the file is right before starting to charge the phone all the way to full.
So, has anyone tried this lately with success? I'm a complete noob and have no idea about rooting, but might look into it if this really works for the Li batteries.
,this is how i calibrate my battery,before i have 45min of standby it will decrease from 100% to 99% but now it is 2hours & 34min before it go from 100% to 99%,i felt the drain after 2 weeks of overusing my phone (1week playing paladog and 1 week flashing different roms,kernels and theming my phone with different launchers),
- Charge your phone to 100% while it’s on.
- Unplug it from the charger, power off, then charge for 15 minutes with it in a powered off state.
- Unplug charger from phone. Power it on, and then charge 15 minutes while the phone is on.
- Calibrate battery using battery calibration by NéMa then unplug charger reboot.
- Power on, charge for 15 minutes then unplug.
- Finished.
note: deleting battery stats(calibrating) don't increase your batterylife said by others and it is just a placeboo and i believe in them,but it fix my battery drain so why don't we give it a try,there is nothing to lose,battery drain is so annoying.
,thanks to NéMa for the awesome apps,

That was from LEWA OS, one of the best rom at that time...:good:
First and foremost, a Google engineer debunked the idea that batterystats.bin has anything to do with how the phone charges. By deleting it, you're actually inconveniencing yourself, as there will be a short period in which you won't have accurate stats.
Secondly, the O1 has a lithium ion battery. Lithium ion and lithium polymer batteries don't need to be calibrated, as they have no "memory" effect (you can read more on that here).
Moreover, these batteries have built in charge circuits that protect and regulate the battery. Ever wonder how the phone knows the battery temperature? It's pulling it off the charge circuit. That same circuit also prevents the battery from ever being overcharged or discharged fully, which is why that convoluted guide about calibrating your battery by draining it to "empty" and then recharging it to full doesn't work. Worse yet, intentionally draining your battery is actually counter-intuitive, as lithium-based cells wear more as their percentage of discharge increases (you'd be hurting the battery in your effort to calibrate it).
Your instructions aren't detrimental, so if it works for you, go for it. However, based on my understanding of these batteries, it seems to me that this procedure is inconsequential.
Besides, a new battery for the O1 is only $6 USD on Amazon or Ebay.
Not sure why, but I restarted my phone and it went from 50% down to 5 % power? Had it on the charger all night and it was still at 5%?? Took it off the charger for a few hours and im still at 5%. Tried wiping stats and had no luck? Any Help??

Drain all battery and charge it from zero. Let it be fully charged before starting it. If you run CWM you can wipe battery state.
Your question is in wrong section in the forum. Try starting the thread in General.
Cheers
+1 this -- and some additional detail...
Wiping battery stats does NOT improve actual battery life. If done properly, and coupled with a calibration cycle, it can increase the accuracy with which your battery reports its current charge. Ideal process is as follows..
Charge to 100%
Reboot into CWM
wipe battery stats under" advanced"
Reboot
Charge back to 100%
Let it DIE (go to 0%) from normal use, DO NOT charge it during the cycle
Re-charge to 100% and you're all recalibrated.
From the sound of it, don't be surprised if your phone sits at 5% for hours. After the calibration, your battery history should be a relatively smooth, downward sloping curve.

Check Settings>Battery Information>Battery Usage and see if a process named RILD is using a high percentage of your battery usage. That process - a very necessary Motorola radio daemon - is wreaking some havoc by causing very rapid battery discharge and also preventing normal charging.
No solution for you but thought I would let you know before you try too many different "solutions" needlessly.
Thanks!

most people here are changing ROMs...and most of the time people say that some ROMS are a big battery drainer..
some move to other ROMs because they noticed that the battery performance of the ROM they are using is changing..
this happens because all the records on the way we charge are saved on the battery stats..sometimes our battery meter says the wrong information. that is why we have to calibrate our battery...we usually do this by going to CWM and wipe battery stats..
but are we really doing it the right way?
here is my guide to do this in the proper way:
i know some of you are using battery calibration from them the market, but all it does is just delete battery_stats.bin from system..But the truth is, the system is still writing the old battery stats if it's erased online...So the only solution is to delete it through recovery...
this is what you need to do:
1.Install Battery Monitor Widget from Market for Monitoring
2.Charge your phone to 100%
3.When done, restart your phone, but go to CWM recovery
4.Go to advanced -> Delete Battery Stats
5.Reboot, you should get battery about 90-100% (depending how much margin has been wrongly calculated)
6.Open Battery Monitor Widget to monitor the voltages. the maximum voltage is 4200mV for Li-Poly battery. Try to reach that value before disconnecting the charger.
7.Before the voltage graph getting dropped, Disconnect the charger immediately. for me it is stopped at max 4190. your mileage may vary.
8.You're done, your battery is calibrated..
kind regards,
baiclark

Never let the battery drain to zero, it's bad for you battery. These aren't the old Ni-Cad batteries from the 80's but Lithium ion batteries If you want to reset the battery stats just download Battery Calibration from the play store. Charge phone to full and then hit Calibrate and it will reset your stats. Unless something is different with the GS4 or their TW OS any newly installed rom should have this done after installation

The statement about li-ion not being akin to ni-cad is correct. The rest is not.
No app is capable of battery calibration. The myth of wiping battery stats to calibrate the battery was clearly and concisely debunked a year and a half ago. Apps such as Battery Calibration ate pure snake oil, as they do not affect battery indication in any way, shape, or form. Additionally, there is absolutely no benefit to wiping battery stats after flashing a rom.
The fact of the matter, as verified by Battery University, is that a complete discharge/charge cycle is the only method of "calibration" available to an end user. By performing a single cycle, the charge and discharge flags are reset. Only a single cycle is needed and this is something that need be performed more than a few times a year, as it wail shorten the battery's serviceable lifespan.

Well a friend of mine had the same issue with "stuck battery %" and that did the trick soooo just helping out with what worked for another is all. whatever
That actually didn't do the trick, as nothing relevant to reported charge is contained in the file that is wiped. While it may seem logical to ascribe the fix to a proximal act, it is actually a case of post hoc ergo propter hoc.

Neither did this. The battery calibrator app did nothing either. My phone is still showing a percent up top that is not what shows in settings/more/battery. More news, my phone showed this morning, after I unplugged it from all night charge, that it had been running on battery for 8 hours 2 minutes. The whole battery status is fubar somehow.

That's the only thing I haven't tried. Will do that today. Will report.
Didn't work. Gonna have to dirty flash the ROM.
My S4 (2 months old) dies with the battery at 20%. After reboot (plugged in) it still says 20%. Why does that happen? It should say 0%!
Update
It seems that the battery gives an incorrect fake voltage sometimes. To correct that I turned the camer flash on, using a flashlight utility, and after a few seconds I clicked the quick start button in the battery calibration utility you can access dialing *#0228#.
Now it show 11% that should almost be correct, and it's now charging. I am charging it in slow mode at 500mA just to give it a proper charge.
I'll update you as soon as I have results.
Second Update
Nothing. I think the battery is broken.
It dies at about 20%-30% and when the phone restarts, plugged in, it says it's 20%.
