When you recalibrate your battery, it takes a few life cycles for the battery to stabilize and for Android to get an accurate reading. First life cycle is alway short. Of course, don't play with ROMs so much it may damage your phones read only memory.
I will post my battery life soon, I'm still waiting for the battery to deplete, I haven't recharged my phone in 4 days now after I calibrated my battery.

Wow 4days is huge,iam getting hardly 1day battery after calibrating yesterday....
Actually i removed my phone before getting the 100% notification....
So should i wait for battery to improve???
By the way,when did you calibrate???
Should i calibrate again????
If this wont work i will try terminal emulator method...
So in this method do we need to charge 100% or discharge completely??
Some precautions or just write those commands at any point of charge???
Iam wondering how to thank from the xda app
Thnx to both of u

Same problem here.
Battery drained from 100% to 60% in 3 hours, then to 15% after 5 hours. phone super hot! Widget showed temp 42°C !
Not even used the phone for more than 15 min! REALLY!
Then calibrated before 3 days, now a max of 1 day battery backup only.
Plz help.
And 1 life cycle means I must let the phone charge 100% then let it discharge till it's switched off.
And I should repeat the cycle.correct me if I am wrong.
And I have the habit of not charging to 100% in a single charge session, 2-3 breaks, should I change it?

clarkkov said:
If your phone is hot without you using it, something is running in the background, that shouldn't. Which ROM are you using and which tweaks/fixes have you applied?
One battery life cycle means battery drain from 100% (fully charged) to 1% (fully discharged). Your phone does not have to turn itself off, but make sure it is at 1% when you begin to charge it again. This is important only for a few cycles after calibration, afterwards you are free to charge it as you wish, but while calibrating it's highly recommended that you don't interrupt the charging process (4Hrs).

I am using rooted jpd from samfirmware, no fixes except sdcard speed fix, previously it used to give a good battery backup.
And apps do run in background.
Should I set autokill level to high in task killer?
And I will take care of charging.
Thanks for support.

on DDJP2.. getting a horrible backup since i have updated thru KIES. generally on jg6 used to get almost 1.5 days which has come down to 12-16 hours now. trying to calibrate my battery with app 'battery calibration'.. calibrated once.. but still no change. read somewhr that we get the same backup for first few times even after calibrating.. but to get sure i am writing down my process.. plz chk if m doing right or not ..
1. plug in phone with charger
2. wait till 100%.
3. press battery calibration or delete batterystat.bin with the help of root explorer.
4. unplug charger and use it till it discharges completely.
5. charge again to 100%.
plzzzz chk and tell.

plzz someone reply.

I have a question about batery drain. Apps on backgroung are drainning lot of batery? May i have to stop them always?

Yes.
You need to be aware that wireless services are draining the battery the most. If you are not using 3G - switch it off, same with BT and WIFI. Widgets that update frequently also drain the battery fast, background data, auto sync services/features are battery killers, too.

Thanx for the reply.. i have calibrated once more.. but already showing 80% after hardly 2 hrs.. no clue whats going on... ppl with JP2 shud come up with thr battery backup to get confirmed.

and last thing am waiting for is that someone said .. battery life is worse for first few cycles after the calibration... thats the last hope... :'(

Thx for the aswer, i thought that all the background data are drain lot of battery. I'll try to calibrate and switch off all the thing i can and see if my battery lives more time

Hey there,
scince I use BatteryLeftWidget, I can see that my battery voltage only reches 4171mVolt.
So, batterystat.bin delete doesnt help, so anyone an idea where to put the 4200mV ?

battery not charging to 100%

new to the atrix.
I installed the latest oat update, and the phone was @ 70% after charging all night. I also noticed it discharge updates only by 10% increments.
I installed the homepage Rom, and it charged overnight to 93%.
I've applied the battery fix, but that only seems to stabilize the display (I noticed it fluctuating before the fix)
is there a fix? I've done calibrations on phones, but I needed to get 100% and the charge while off. Not sure how I can calibrate if I can't get a full charge while on.

Use recovery to wipe battery stats. If it still fails to display 100% when charged shut the phone off. Take the battery out, then plug the phone in. Wait until the "?" on the battery shows up. Then put the battery in while it is still plugged in. Leave it like that for about 30 mins. When you click the volume button the battery will show only 5-10%, but turn the phone on and it should read 100%.

I'll try that. I already wiped battery a couple times in cwn

OK, then the 2nd part should do the trick. It works for me anyways. Once you do see 100%, wipe batt stats again and let the battery die, then charge while the phone is off. Should fix you up.

You might have to wipe battery stats several times. I had an out of the ordinary calibration problem between flashing roms and had to wipe everything several times before it started working properly. Also note, that charging up to 95%-99%, and unplugging and plugging back in and slowly charging past 95% is common and not a problem. The software is estimating battery charge. And if you do charge past 95% and unplug its ok if it quickly goes back down to 95% and then tapers slowly.
I voided my warranty and your mum.

You have to wait for battery to go beyond 95%.
It takes time but it goes their.
My personal experience.

Just drain the battery til it dies. Then plug it in over night while you sleep. Once you wake up wipe battery stats and everything should be good.

I think he has tried both of these methods. I know I did. What I told him to do was the only thing that worked for me.

OK J, it looks like that fixed it.
Although battery showed 4169, and I saw others with 4200
Thanks issued!

try discharging until the phone shuts off and charging it again without turning it off.

Hmm...battery should show 4203 when fully charged. Mine has actually displayed 4205 a couple of times.

PROPER battery calibration... is getting on my nerves :/

So, I am using MIUI 2.1.12 with LorDModUE 8.6 CFS 2WCR kernel.
I have installed 4EXT Recovery Controller and CurrentWidget.
With CurrentWidget, I monitored the battery while charging until it reached 0mA (which means the battery is as full as it can get).
With 4EXT Recovery Controller I removed the batterystats.bin file.
I drained the phone until it shut itself down. Then I charged it (without powering it on) until it was full (LED was green).
I power on the phone... 99% battery.
I plug in the charger... it says 26mA (which means it would reach 0mA as in full charge in another 20-30 minutes).
WHAT THE HELL?!
This never happened while I was using the default CM kernel included in MIUI. Only happened with Tiamat and LordMod.
--
Seriously, guys, what is the best way to calibrate the battery?! Perhaps I should not have let it shut itself down, but plug the charger when the phone was at 1% (which lasted for another 20-30 minutes, by the way)?!

if I don't remember it wrong the LED turns green at 90%.

afair the battery doesn't get charged during booting. which means that you probably lost the 1% during boot.

I also used the same method and got it calibrated correctly
but is their any other way too ?

The LED turns green on AOSP ROMs at 90%, when the phone is ON, as far as I know. When it is OFF, it works fine (goes green at 100%).
I want to hear from the developers / those that know how these codes work and stuff... Cause I don't want to look at my phone how the percentage goes down so fast, then, when it reaches 10%, I can play Pocket Legends for another 20 full minutes -.-

The battery doesn't charge to full capacity first time around. When I used to calibrate the battery I would charge until it was drawing 0mA, then reboot; it would be drawing about 26mA, so I'd charge to 0mA again and reboot; it would now be drawing about 15mA, so I'd carry on charging to 0mA, reboot, repeat, repeat and repeat until it eventually continued to draw 0mA after a reboot. Then I'd delete the batterystats.bin file.
As one of Google's engineers says, deleting your battery stats isn't going to improve your battery life. I haven't done any of that for a long time now and I've noticed precisely no difference (except for the extra time I've gained by not having to wait for it to finally charge up to full capacity).

I know about Google's statement.
The battery would drain fast, then, when it reaches 1% or 5%, you would be able to use your phone like it had 30%. Just that it shows the values wrong. Calibrating the battery should fix that...
Anyway... I'm not going to struggle any further.

I'll tell what I've done;
- I have installed Battery Balibration app and CurrentWidget,
- Waited battery charging till reached 0ma,
- Removed battery stats and restarted,
- Then waited to drain battery and shut-down itself,
- I connected USB charger to PC and TURN ON THE PHONE !!
- Again waited battery to reach 0 ma,
- Then plugged off and monitored that current widget shows the range btw 3-10 !!
I don't know exactly if it helps but, maybe you should turn on your DHD while carging..

Right, with Battery Calibration i have solved my problem with battery, now i can use all day without charging.

Sorry if my question is a silly one...
what's the point in calibrating your battery? I mean... except for the stats (and I guess, the percentage in the bar), do you improve your battery life by calibrating it?

I don't really know. It would be silly for the Android system to display the battery percentage (up there, in the status bar) by reading the batterystats.bin.
My phone's battery level drops somewhat fast, then, when it would reach 30% or so, it doesn't drop as fast. Also, at times, when I reach 10%, 5% or even 1%, I am still able to play an intensive game like Pocket Legends for an extended ammount of time (30 minutes, for example). Pocket Legends is CPU/GPU intensive and it also requires an active Internet connection, so I'd say it's pretty power hungry.
I don't really get the entire purpose of calibration. I have done it and I can't seem to notice any difference.
I'm going to do it again, now, because I switched to a Sense ROM (RunnyDrOiD). I'll monitor the battery with Battery Monitor Pro. When it reaches +0mA, I'll reboot and so forth so forth until it's drawing 0mA, although I doubt I'll resist that much time, so I'll just delete the batterystats.bin after a few reboots, when it reachs 0mA.

If everybody knew the meaning of the word "calibration" then nobody would talk such nonsense.
Calibration improves the accuracy of the percentage shown!
The illusion is that you improve your battery life with it....

As I said... calibrating the battery may fix the "problem" where once you reach 1% / 5% you can use your phone like it still had ~20%.

I'm gone test it too...

Hi there people, I didn't find any battery thread similar to what I'm going to say so I'll spam a little bit
I've just found as I was fooling around this: http://www.ebay.com.au/itm/PowerSki...AU_MobilePhoneAccessories&hash=item20c1a1c8ad
It suppose to be a silicon case with a battery build in(1500mah ..not bad), I don't know the dimensions but I just someone might think it as a solution to our 1230mah small battery(with this you have a total of 1730mah which is plenty)
P.S. To mods.. feel free to delete my post, I just wanted to inform the people about a solution that might be handy

Terrible problem battery

Hi!, im terrible problem for my battery
a long time (1 month) i bought two batteries for nexus 4 Originals, but the two battery only charged to 91% (long time jump direct to 100%) but low charged 9% without reazon
im try all for the solution the problem:
Reinstall kitkat 4.4.4 from adb
Franco kernel
CWM don't option wipe battery
Calibrate battery too, failed.

first of all try a battery calibration program like this: https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en
maybe it is a calibration problem.
as far as i know batter stats are not erased with a factory reset
then try an app like this :https://play.google.com/store/apps/details?id=ccc71.bmw&hl=en
it should tell you the battery capacity and see if everything is working as it should.
good luck! i hope that will solve your problems, or at least find out what your problem is!
P.S. if it is an app related problem, or wakelock related you can find it with betterbattery stats.

That battery calibration app is a placebo. The batterystats.bin file doesn't do anything to change the microcontroller inside the battery pack itself.

Allow the phone to discharge fully until it turns itself off, by normal use and not using a battery draining app (or a benchmark). Then charge slowly and continuously until full, without making the battery hot, eg. by USB port on computer.
If you discharge too quickly you risk getting the red light of doom.

Last few percent takes longer to charge, I think this is by design. Mine behaves the same way.

Battery problem

Hi,
I have problem with in Jiayu S3 2GB. Under 50% battery drop to 0% in few minutes. Also battery doesnt last long , max 3 hours screen time and it is problem to use it whole day withnout charging, but normally screentime should be around 6 hours what i read.
I recived phone with Android 5.1 2015-06-23 tryed flashing newer version 2015-07-14, also tryed battery calibration, fully charging, discharging few times and still same.
When is fully charged voltage is 4,2V (measuded with app battery calibration) at 50% is only around 3,6V (this is almost 0 capacity for lion battery) and is turning off at 3,4V.
Have anybody simmilar problem? It looks battery is bad not just software problem, but dont understand that it is showing 50% for that low voltage.
Thank you

IF you are on lollipop then its software problem as 5.1 seem to have the battery bug, and never calibrate battery on MTK devices, Calibration apps mess up MTK phone,they are not made for mtk devices.

I recieved phone with defective battery, after changing it dont have any battery problem even with Lollipop.

I noticed that battery discharging very fast below 8% (Stock 4.4.4 13.08 and other KK versions)

Well, i had different problem
My phone didnt charge, no matter how much i change cables or chargers.
But when the device was shut down, charged well.
I bought mine from pandawill, so i sent them a mail,and they sent me another battery...
In the meantime, the problem had solved, maybe the battery calibration i did helped.
Anyway,i got now 2 batterys...

I also have the problem and have the following conclusions:
1. Battery level will be displayed correctly after a reboot. Otherwise, the battery level indicator doesn't change as quickly as it should: it doesn't go up as fast while charging and doesn't go down enough when in use.
2. The point where the battery indicator starts going down by about 5%/minute varies and is in connection with the time it has been used. After two days without charging and without using the phone for more than one or two phone calls, it happened at around 5%, while lots of screentime made it happen when the indicator was above 50%. Some experimenting made it clear that it's not the battery's fault (in my case, at least) but rather a software problem.

I have problem with in Jiayu S3 2GB. Under 50% battery drop to 0% in few minutes. Also battery doesnt last long , max 3 hours screen time and it is problem to use it whole day withnout charging, but normally screentime should be around 6 hours what i read.
I recived phone with Android 5.1 2015-06-23 tryed flashing newer version 2015-07-14, also tryed battery calibration, fully charging, discharging few times and still same.
When is fully charged voltage is 4,2V (measuded with app battery calibration) at 50% is only around 3,6V (this is almost 0 capacity for lion battery) and is turning off at 3,4V.
Have anybody simmilar problem? It looks battery is bad not just software problem, but dont understand that it is showing 50% for that low voltage.
Thank you

Try to go battery settings and find out what application is eating your power.

Hi! I have this phone and few weeks ago I had a similar problem, when my phone had about 20%, it spend a lot of battery and in some minutes, it was without battery. I installed the Xtreme Rom and this was fixed. I hope you can fix your problem too with this.
Sorry for my bad english

Battery not charging when on - Solutions ?
Hi all,
My Jiayu will not charge when the fone is on, will only charge when switched off.
Any suggestions ?
Thanx Geoff

Known problem.
Saw it at my phone and in another phone.
How to solve: charge with original charger and cable and then switch to the other charger.
It worked for me twice.
Play it a little if its not working, switch cables,chargers, turn on and off...
Good luck.
