WOW

When I was a child I thought and ate like one. My parents chose my meals out of concern for my welfare and health. Now that I'm grown the choices are mine to make, and responsibility is on my shoulders alone. Things done in moderation are usually not much of a issue, be it comments or opinions, But forcing an adult to believe or consider anothers belief does no one good.When we believe things we know it doesn't mean all the relevant facts are known.If I feel alcohol is bad I won't drink it .What another does is his choice and not mine to critisize. Let's treat others the way we want to be treated,as ADULTS:):good: Think I'll try this app.
[Android Apps and Games] Kameirus:
how about just goto the link in my sig about it

and you will read from a google dev that it does nothing at all
[Android Apps and Games] jayRokk:
How about you take the above guys advice and read actual facts.

Or maybe Google how these kind of batteries work and need no calibration.

Or maybe Google why devs, not only here but from the actual AOSP developers advice not to use these apps.......

Facts!! Not opinions..

I have a problem with my Nexus 7 battery, It stays at 100% for two days, then it drains until 80% quickly, and then it changes to 0% and shutdown. When I connect the tablet to AC it begins charging at 80%, so I deduce it is a calibration problem.

If this kind of APPs don't work, what should I do?
[Android Apps and Games] najaboy:
The Nexus 7 suffers from poor quality control and your issue is not uncommon. It is typically caused by the battery's connector not being properly seated. The back of the tablet is easily removed and you can then unplug the battery and replug it.
[Android Apps and Games] jmga:
I have just done it and it didn't work.
[Android Apps and Games] deom2i:
Guys,

Im using this app and my battery is draining constantly while charging is this the way the app operates? :eek:
[Android Apps and Games] toxicpaulution:
Can we get a close on this app please? Just taking up space and time.
[Android Apps and Games] najaboy:
Check out the Nexus 7 Q&A forum. Battery issues are unfortunately relatively common with the N7 and there are various other potential fixes posted there.
[Android Apps and Games] tiflao:
When my baterry is 100 % , I press the calibration button , but the pone must conected to the charger? Or not?

Thx
[Android Apps and Games] najaboy:
When your phone charges to 100%, simply unplug it from the charger- no app needed. Android automatically does the exact same thing this app does each time you unplug your phone after a full or near-full charge.
[Android Apps and Games] ehsan453:
How do I do this?

1. Use your phone till it shuts off

2. Before charging it turn it back on and do it again.

3. With the phone off plug it in and recharge it overnight or atleast 6-8 hours.

4. Turn it on and and use Battery Calibration - by NéMa.

5. Use the phone till it dies again and then recharge and use phone as you normally would.
[Android Apps and Games] najaboy:
6. Be secure in the knowledge that the one and only thing you did was damage your battery and shorten its serviceable life.
[Android Apps and Games] ehsan453:
You mean this procedure is harmful for battery? Therefore, what's your issue for battery calibration?
[Android Apps and Games] najaboy:
Lithium based batteries have a finite number of charge discharge cycles and unduly stressing the cells of the battery, such as in the second step, will have a detrimental effect.

There really is no such thing as the calibration that this app purports to do. The rationale and methodology that it is based on was officially debunked last January by Google's Android Framework Engineer.

The singular method of “calibration" available to an end user would be a single full cycle on the battery every now and again to set the charged and discharged flags from the battery itself. Even then, the benefit of that it's questionable since
[Android Apps and Games] ehsan453:
Plz let me know what should I do exactly for battery stats after flashing a new ROM?

Tnx
[Android Apps and Games] jayRokk:
Nothing
[Android Apps and Games] najaboy:
This. Wiping battery stats in conjunction with a rom flash is completely pointless and unnecessary. To reiterate, nothing that's being wiped has any bearing on battery life or battery indication. Ignoring that fact for a moment, if you wipe data prior to flashing a new rom, the partition upon which the file in question resides has already been formatted. Furthermore, the file is automatically wiped upon the simple act of unplugging your device after a full or near full charge.

Hi all.

I have a problem with my Galaxy ACE (even flashing a custom rom or a stock rom) that doesn't seem to be listed here.

In the main screen of the Battery calibration, it's say that the battery is fully charged (100%) but i only have 4Mv ??

When i plug the phone, it goes from 0% to 100% in only 2 minutes...

In fact the battery doesn't seems to be fully discharged, because when i plug the phone without android launched, the green progress bar of the battery is at 75%

Does't it mean my battery is really out of order :crying::crying::crying: , or it is also a poblem of calibration ??

Best regards from France
[Android Apps and Games] jayRokk:
Have you not read anything we've posted??? Please please PLEASE! Read before posting... This app DOES NOTHING for you! Whatever it says or does is false!
[Android Apps and Games] sstassin:
Hi eyronic.

I am having the same issu than you with my Galaxy Ace. I'v read onnly the "first" 32 pages of post and i didn't get the answer at this time.

Did you find your answer ? I'll read the others pages this afternnon.

[Android Apps and Games] lampardlb:
Hi Marosige,

Thanks for your effort, it's really brilliant. But it seems that I've made a stupid mistake: my battery was not shown before, when there was 3500 mV it shows 1%, but I calibrated it anyway, so I think now the machine regards 3500 mV as 1%. The thing is, after I turn it off, I'll never be able to turn it on again because I think it will only turn on when the battery is 5% or higher, which will never happen. Do you know how I could change it back again please, thank you very much!

i followed the instructions.. i charged my batt till 100% then use ur app.. drained the batt till my sgy turned off.. then charged to 100% while still its off.. the app shows my batt voltage to 4mV only.. now my question is should i wait my batt attain the 4200mV w/c ur app description says to get full charge?
[Android Apps and Games] Pfeffernuss:
The app does nothing, so no worries. Just charge the device and be done with it. Deleting battery stats file is useless.

unable to calibrate battery

Hey guys,

I am having problems calibrating the battery of my Samsung I9300. My battery is empty within 3h from taking the phone from charging. I have calibrated the battery according to the instructions here, but that doesn't help. No apps are particularly draining according to the analysis by for instance Battery Doctor), also since the same problem already existed with the stock rom and directly after factory reset. When I place my battery (which then says 30% left for instance) in another I9300, here it gives still 88%. So I suppose the battery is fine, there is just wrong communication between the phone and battery? Or maybe it can be a hardware instead of software problem?

Hope somebody has an idea and can help..

Thanks in advance!
[Android Apps and Games] aumshethia:
Some thing really strange is happening. After installing Shpongle rom, my battery is draining really fast.

I followed the procedure mentioned ie. I waited untill my phone was drained completely and shutdown, then i charged continuously (phone still off) till the led turned green (indicating 100%). After this, i switched on my phone (which was now at 100% charge) and i ran "battery calibration app" (that i had downloaded from play store) and then used it all day normally whole day.

The charge lasted about 12 hrs before getting completely drained.

Now as per recommendations, i switched on and plugged in the charger, but when i saw the home screen, it showed 42 % charge :confused:

How is that possible ? the battery couldn't have charged from 0 to 42 % in 10 secs of booting up.

Can someone please help me out to get my battery correctly calibrated.

is it healthier to have more than 4200mV showing up in batterystats app??
[Android Apps and Games] cvele.p:
This app is garbage!

I broke mine lenovo K900 with it! Dont even try to install, damage is guaranteed!

App change register file and it is only way to fix it is to format entire memory and flash factory ROM.
[Android Apps and Games] boko_to:
are you sure?

Are you sure the app caused the damage ? because i have used it on several occasions with no problem.
[Android Apps and Games] cvele.p:
No, I am not sure, but after did unistalling everything go nice.
[Android Apps and Games] Ivan Zakharyaschev:
could be checked if it were open-source (highly desirable for an app which uses root)

Hi,

the best way to check that the app is not harmful would be to inspect its source code. It's a pity that this popular and small app doesn't seem to be open-source.

Firstly, it's highly desirable that an app whcih uses root access is open-source and can be audited by the community. (I'd like to use it, but I won't install it because it's not open-source.)

Secondly, being free software (open source) would be beneficial for the maintenance of the app, and it further development -- with the help of the community. What if we need to adapt it to a new device or OS version? What if we need to fix a bug? What if we need to add feature? ..and the author is busy with other things. The community could improve a free software, but not a closed-sourced app. Free software would have better and more guaranteed future.

---------- Post added at 08:26 AM ---------- Previous post was at 08:15 AM ----------

Perhaps I'm wrong. I simply couldn't find a link to the source code here.

Is the app open-source? Why not make it open-source (if no)?

i9100 battery calibration

i "calibrated" my battery yesterday on my i9100. pressed calibrate when it said 100% @4188mV. now i was using my phone normally and noticed that the battery is draining at much higher rate as it was before. opened up battery calibration app and it says 40% [MENTION=722057]380[/MENTION]0~mV. this doesn't make much sense to me because the maximum mV was at 4188. something broken here?

Galaxy Note 10.1 2014 new batt capacity

I've installed new battery with much higher capacity.

But system ignores battery voltage and shows remaining capacity guessing it from current drained from the battery.

So I get 0% while voltage is 4.1.

The program successfully deleted the file, but system behaves the same.

What should I do to fix system battery capacity value?

what if my phone is with an original rom, would it work?

hi

i've read some comments where it's mentioned that the phone should be run with a rom

but my one is with the original one

would the application work? and i've do what is saying in the instructions after installing the app and i didn't see any changement or amelioration

why?

sould i let the battery go to 0 and charge it to 100 without a pose??

please answer
[Android Apps and Games] jayRokk:

[Android Apps and Games] SideSkroll:
Question regarding maximum mV.

Hi, I know this whole "battery calibration" thingamajig is supposed to be a myth but I tried it anyways just to see if there's anything different with my phone...

Anyways, my question isn't related to the procedure or app itself.

It's more related to the mV a fully charged 3000 mah should in theory have.

Mine can go as far as 3360 mV fully charged.

Is this normal? Should I be concerned? Is there anything wrong with either my chargerand/or battery? I confess that even though I know MUCH about a lot of things this is NOT one of my fortes... :D so any info would be very much appreciated.

Tanks to anyone willing to give me a hand.
[Android Apps and Games] cliffordd:
These are two totally different measures.

3000mAh is milli-amp hours while 3360mV is milli-volts.

mAh is a measure of capacity, how much charge your battery can hold. As a battery ages the capacity drops. To charge a battery you must provide a voltage across the terminals. When the voltage is greater than the nominal battery voltage, the battery should start to charge. Although the voltage is useful for predicting the state of charge (empty, full) it really gives no indication of capacity.

I have a problem, please help me

Hi, I am using your battery calibration for year in my phones.

but I have a problem now, in new update xperia z1 lilipop 5.0.2, there is a bug for my phone that when completly discharged and turned off, when I connect charger, in charger very slow for example 1 percent in half time, so I have to disconect and re conect charger or turn on the phone and start charging it to fix this issue.

so, i cant do the step "it is recomended to fully charge from empty battery WITHOUT BREAK"

is it cause to not completly calibration? what can I do?
[Android Apps and Games] Geoffxx:
I have read the google devs opinion on this and I also have an understanding of what they are talking about, the battery in your phone is a bit of a weird one, andoid does it's best to estimate the condition of the battery charge and display it on a meter, the OS also reacts to this when it decides that your battery is flat and shuts the device down, is the battery really flat - is it really fully charged at 100% - that is the question, the OS does its best to estimate the charge state by building a profile of the battery from when it gets charged for the first time and then goes through a learning of charging cycles and discharges all the time building a profile. There is a theory that this profile gets messed up through time and starting the leaning cycle again may have benefits for some people and some devices, it could also go the other way.

so here is what happened to me

My xperia Z1 had a full battery drain and was charged when off, when I restated the phone it was at 100% but once it reached 50-55% it suddenly went down to 2% and gave me a warning that the battery was low, this went on for a while until I eventually fully charged it and deleted the batterystats.bin file then rebooted the phone, from that time I had no more issues..........until now

I updated to LP a couple of days ago and all was well until I rebooted the phone at about 80% battery, when it restarted I got an immediate warning that the battery was low and it was showing 2%, so it went from 83% to 2% over the time it takes for a reboot, now I am going to delete the stats.bin file again once fully charged but I have a feeling this is related to LP more than anything else but is hard to tell

The google people say that the process will not improve battery life which I would agree but it may just add some linearity to how the charge cycle is displayed and giving you a better more accurate idea of the true battery status. hardware changes as it gets older, a re-profile of the battery status may not be a bad thing
[Android Apps and Games] dnabyte:
Is it possible to run on unrooted devices?
[Android Apps and Games] undercover:
You didn't read all info, and missed the most important bit. That file gets wiped every time phone reaches 100%.
[Android Apps and Games] Geoffxx:
wiped or modified ?

It could well be that this file is not going to alter the profile if the battery function, what I do know is that something changed in LP and has been reported on many forums and is experienced on many different devices including Nexus

My latest experience the other day was to have my phone shut down again going from about 80% charge to zero after a reboot, the phone was charged for 10mins and when rebooted was back at 80%, something is not right with this operation on LP, I also have 2x Z1 phones and both behave the same way since LP update

Interesting there are two Batterystats files with lightly different file names

What I believe to be the real problem here is how LP interprets the battery current and load and is being interpreted incorrectly Sony may have some code that sits between the LP layer and the Battery that is not calibrated correctly - just a guess

but there is definitely a problem and it is not the battery

Hello guys,

Yesterday I installed a custom rom on my phone. After this my phone charge very slow ( when it not used). When I use the phone while it charge the batery drains. I just installed the app. Pressed the Calibration button and now I am waiting to a empty batery. Will it help or is there a other way ?

Just downloaded this app. It asked for root permission which I didn't grant. I pressed the button to calibrate my battery and it seems to have solved the problem I had where my LG G5 would not charge beyond 98% on one of my batteries. After 10 mins on charge after running the app, my phone reported 100%. Somehow doubt that this is a coincidence. Really not sure why the app is so large or what else it does while running tho!
[Android Apps and Games] EEngineer:
I also have an LG G5. Thanks for your post.My G5 used to take a long time to charge from 98% to 100%.

I installed the Battery Calibration app. After charging to 100% I clicked Battery Calibration, then rebooted my phone, let it discharge to 5%, then charged to 100%. It seems to have solved that problem and improved my battery life.
[Android Apps and Games] EEngineer:
Oh I forgot to add, after the reboot and you charge to 100%, you need to reboot your phone again.

[Android Apps and Games] zeppelinrox:
And how does it determine what 100% is? If you aren't going with a mV reading, this app isn't doing anything. If the battery isn't calibrated, and it's only at 3900mV and android says 100%, you're really deleting the batterystats.bin at 70%.

I don't see any. If you rooted, you can just put this in a gscript (with superuser permissions):

mount -o remount,rw /dev/block/mtdblock6 /system
rm /data/system/batterystats.bin

Unless you're using mV and doing a bump charge, or variations thereof, then I doubt "correctly" is the right word.

Go with a mV reading.

Battery Monitor Widget is the one to get.

If this app is using an uncalibrated reading of 100%, then I don't see the point.

Sorry to be bursing bubbles, but this app has room for improvement.
