The issue lies in the internal charge regulator inside the phone (usually limited to .5 - 1 amp), this is nowhere near enough to reverse the oxidation in a lithium battery. You WILL have to take the battery out and charge it with a high current charger (1c rate = capacity). So for your 4.8Ah battery get a charger that can charge at 4.8A let it run all night. I have a 12Ah battery and charge it with a modified 10 amp 5 volt power supply from jameco. You might need to do the same with yours to get it fully charged as I had the same problems. The issue in the software is that it sees the battery is at 4.2 volts and STOPS charging the battery, in reality the battery must be able to rest at around 4 volts under no load to be considered charged. Look at it this way, if your charger (inside the phone, not the wall wart) is 500 ma and your battery is 4.8Ah divide 4800 / 500. This is the time it takes to charge the battery, however this is a lie, it takes much longer than that due in part to the ESR of the battery. Mind you, you will have to discharge the battery fully once or twice and the charge it fully. However like I said earlier 500ma is nowhere near enough current to fully charge a lithium battery of that size. Makes we wonder why all these high cap batteries don't come with a high current charger. If you're seeing all these stories about how the battery lasts longer than the stock one, well it will, but it's still no where near where it could be with a high current charger. I know grammar here sucks, just trying to get this out here before my ADHD drags me off to search for bunnies on google.
[Android Apps and Games] Dmw017:
One quick question about how this calibration works.

After you click calibrate, are you not supposed to plug it into any charger at all until it runs down to 0%, then back to 100% fully without turning the device on or disconnecting the charger at any point ?

Like right now I just calibrated the battery, but kind of need/want to connect my usb (to organize the storage, etc) which can't be done without it charging the device.. and i dont want to mess up this whole ideal calibration process.

I know there is some way to disable usb charging from your comp but either way, is the process I wrote in the first paragraph the only way you should do this?

Samsung Galaxy S II

hi there...

i have downloaded your app to my samsung galaxy S II and no matter wat i do i keep getting a Root Your Device Message and it wont calibrate my device although it is charged 100% etc.

do i have to back up my phone and blow away the operating system and start again or what... i am pretty new to the Android world. any help you can offer me would be helpful.

i am running Android 2.3.3 (GINGERBREAD DUKH1) on a GT-19100T on the Vodafone Network in Australia.

Cheers for the help... i am getting about 3 hours of battery life out of it at the moment so any help will go far...

[Android Apps and Games] Stajlerboy:
Does the phone have to be rooted? I have a SGS vith stock firmware and since I updated to 2.2.1 the phone charges to 100% but when I unplug the charger it goes down to 98%.

Can I use this app to fix that on my stock SGS without root?
[Android Apps and Games] Khoops66:
If for some reason your .bin file got screwed up. . This is mainly for people who have flashed a rom and it inadvertently messed up the .bin batter file. I use GingerBlur on my Atrix and this was very helpful since we don't have full recovery mode etc. . .

What's your opinion about above?

Is it possible create thread about your app at other forums? Sure with link to this thread.
[Android Apps and Games] marosige:
I'm working on it.

Sure! :) But only to this thread, not the app please.
[Android Apps and Games] lvnatic:
I used your tool in the morning, unplugged at 100% and 4182 mV and pressed the calibration button. I can't notice any difference, the battery is about the same...

Does this tool do exactly this type of calibration (1st post of the page)? Or it just resets battery stats?
[Android Apps and Games] imakul8:
Thanks, this is just what I needed when I needed it. I like to flash the stock recovery back in between roms. Everytime I want to to remove battery stats I would have to flash to clockwork mod to remove battery stats and then flash the stock recovery again. This will save me that ordeal.:D
[Android Apps and Games] marosige:
Maybe your batterystats.bin file wasn't messed up thats why you can't notice any difference. After you run my app you get a clean bin file. Maybe 2 or 3 days after calibration you will notice that your battery life got better.

This app only resets the battery stats. (step 8 @ the tutorial you linked.)
[Android Apps and Games] marosige:
Root should be enough.
[Android Apps and Games] marosige:
I think it's just the same. maybe it's a little better to delete the file first then unplug, but there's not a big difference.

In version 1.1 I will change the two steps.
[Android Apps and Games] marosige:
I think it's work cause a NAND HD2 is like a Desire HD. Try to run the app. If there isn't any file like that the phone can't delete anything. There is nothing to loose.

Maybe first you can check if the file is existing with Root Explorer or some app like that. You can find it in: /data/system/batterystats.bin

If there is a file called batterystats.bin you can use this. If there is no file like that there unfortunately you can't use it.

Please tell me if it worked! :)

[Android Apps and Games] spookamiester:
I always thought it was a bad thing to run the battery down to 0%, the most I've ever calibrated down to was 5%. Is this step really safe or necessary?

Also, I was under the impression that recalibration if you flashed a ROM whilst connected to a computer or whilst charging in general.

Can anyone clarify these things for me?

Looks like a great app anyway and will make things much more simple in the future

[Android Apps and Games] adl:
2 questions, as i am about to try your app:

1: Will there be any further fixes/ improvements with version 1.1 and when are you gone release it?

2: Before when i cleared battery stats for example in recovery mode i let the phone shut off by itself, and THEN plugged in the charger, which isn´t possible if i want to run the app, right? So should i just start the app with 1% battery left, then plug in charger, wait untill it´s 100%, click "Battery calibration" and remove the charger?

Thanx for a quick response (my battery is now @ 3% so please hurry :D )

Thanks for the info.....i keep the streak on charge regardless of the meyer showing 100% and it completely charges till 4200mV but on removal of charger it shows a dip of almost 70 to 100 mV.. here the issue is not about charging but the issue is tht dell streak is not detecting and reporting this beefy battery...its doing stubborness of detecting only the stock 1530 due to some bloody code that dell put in but noone knows where....if someone can figure that out i wud be glad..
[Android Apps and Games] Digidice:
I charged my battery to 100% and one extra hour, then run this app.

Am i supose to reboot the phone after or do anything other ?

I read the extra info to discharge it after so now i turned on wifi and screen light to 80% then let it never turn off light to discharge it to agein recharge it to 100%.

Are these steps right ?

Thank you

Hi

I have a rooted sgs2 t989. I charged my phone to 100%, unplugged it and charged it some more. But whenever I tried to calibrate my battery using this app it keeps telling me that it needs root access. My phone is rooted and I check SU and it already has root access. Anyone have an idea why the app isn't working for me?

Hi! Sorry that I wasn't in the forum for a while but I had my finals.

I use FTP file transfering if I don't want to charge the battery. There all several FTP servers for android and a lot of FTP clients to your PC.

You can drain it to 2-4% after calibration then charge it.

This app uses Terminal commands so I don't know why is it telling you to root. When the app starts it simply write into the terminal "su" so if it's working with terminal emulator it should work with my app too.

Calibrate, discharge how you want, and charge it. It doesn't matter if the phone is turned on or off during charging.

Yes! Don't calibrate it too often or you will not see any improovements. I calibrated my phone 2 months ago. I will only calibrate it again if I change ROM.

seems like the SGS2 needs to be used different :S Don't know why.

Yes.

It's working on ICS. The app will tell you if your phone is not supported, so you can allways try.

hi..

i install this app on my desire..

but after 100% of charging it was showing 4187mV....

i have read somewhere that it should be 4200..

so that i kept my phone on charging even after it showed 100% in an order to achieve 4200mV..

but it didn't..it always show 4187mV at 100%

any solution or suggestion
[Android Apps and Games] marosige:
+- 20mV can be OK.
[Android Apps and Games] BenEadir:
Hi Marosige,

I hope the finals went well for you?

I have a Samsung Galaxy SGS II and I use your app after flashing new ROMS - thanks for making it.

The one small but VERY annoying problem I have is that after installing your app the phone beeps (or vibrates depending on whether I have it on silent mode or not) when it reaches 100% fully charged. This is really annoying at night and wakes me up.

I know there is a toggle button in the app for turning on or off the "Beep if charged to 100%" option but no matter what way I set it the phone always beeps when it reaches 100% charged.

If I go into the app and the toggle is set to "Beep if charged to 100%" I will de-select it so it changes to "Don't Beep" but if I exit the app and re-open the app straight afterwards the toggle switch has reverted back to "Beep if charged to 100%" :eek:

It's like the toggle isn't working and it's stuck permanently on "Beep if charged to 100%". Is there any way to fix this or alter it so it's permanently set to "Don't Beep"?

Cheers,

Ben
[Android Apps and Games] Locoman_:
Does the application need to stay actively running after you charge to 100% then press calibrate?

I tried on a new ROM last night and after everything was settled I installed this calibration app. Charged to 100%, pressed calibrate and unplugged the phone from the charger.

The app was listed as actively running some hours later but then it either closed or I closed it - I don't remember. Does it matter? I couldn't find any details on this. Thanks.

[Android Apps and Games] MarsWalker:
I have a problem.

My Chinese Android Tablet 2.3.3 show Current charge: 100%, 0 mV (yes the 0mV is very strange but this is a cheap chinese Tablet). It did go from 100% to 15% before asking to be charged.

I used your great app (it is great and worked on all my other Androids) to clean the battery stats and now it goes from 100% to 60% and then it just shuts down.

Of course I don't have a backup of the log :S

Is there a way to make it "work" again ?

The market reports as a "China Telecom Infotmic M009F".

Thank you all.

Okay something is definitely up with my battery or something..... I have a Nexus S 9020T and I'm currently using an MIUI ICS rom with speedy kernel 7 (Which is buttery smooth and has deep idle). But something's weird with my stats. My battery drains like a mad man an the MV is not displaying properly. Right now the current charge is 31% and 3756MV....

I always clean wipe when I install a rom and also clear the battery stats.

My battery life was decent, 16 hours with some light to moderate use (1 hour of wifi streaming videos) but a few days ago the phone became super hot and it drained the battery so quickly. I'm talking 20% per hour but then it slows down to like 10% and lasts about 8-10 hours in total.

For everyone to read:

Well Dianne Hackborn, the Google employee responsible for debunking myths about HW accel in Android has done it again. She has provided us with what the batterystats.bin file is for, and why you DO NOT WANT TO DELETE IT EVER!

Today's myth debunking:

"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/ directory."

No, it does not.

This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.

That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."

It has no impact on the current battery level shown to you.

It has no impact on your battery life.

Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away.

Getting problem with galaxy ace

i have read how to calibrate battery but my problem is, my handset show battery status 55% when i plug in charger after 10 to 15 min battery indicator show 100% as to do, i calibrate battery but after calibration when i remove charger and do nothing with handset (making call, internet, playing game) just keep it on table, after 5 or 10 min later, battery indicator show 80%, so doing nothing 20% battery loss in 10 min,

when i flash new rom and wipe battery status i got about 1 day and 18 hr of battery backup but after first recharge i am getting above problem, i have done calibration 5 times but problem still same,

[Android Apps and Games] Dude_Virus:
You do not need an app to calibrate the battery. This app helps to delete the battery status file. You can even delete the file manually by going into you root folders. Calibrating a battery depends upon how you charge it.

This is what i follow........>

I charge the battery completely until it shows on the screen that it is 100% charged after which I turn off the phone with the charger still plugged in. If it shows 100% there too i then unplug the charger and then reseat the battery and with the phone still off I connect the charger. If the battery is charged completely it will show 100 % on connecting the charger if not then let it be on the charger for another 30 - 40 min to ensure full charging. Once that is done then switch on the phone with the charger connected and let it charge for another 10 min and then unplug your charger. let the battery discharge completly and do not charge the battery unless the phone completely dies as this way your max and min voltage levels are recorded in the stats file. Follow the same process for atleast 6 to 7 charge cycles. Also note the time taken for the phone to completely charge. Once those are completed then when u start charging leave it on charge until your mV shows 4204 mV and let it be on charge for atleast 30 to 40 min longer than what it usually takes to charge. For eg if your phone shows 100% ( 4204 mV ) in 3 hours then let it be on the charger for 45 min to an hour more as this will prevent you from reseating the battery.

I recently bought a 'better' battery for my X8, one that is said to be more powerful.

It is described as a:

"2200mAh High capacity Battery"

I am using FroyoBread V023b on my X8, and quite recently the phone has been turning itself off quite constantly. It isn't just a simple 'turn-off', the phone brings up the little box that comes up to tell me it is powering off.

Will this calibration program help? Or if anyone has more information regarding this whole procedure does anyone have any advice?

Why does anyone still bother with this app? It's worthless. All it does is delete your batterystats.bin file, which does nothing, ZERO, for battery life or battery calibration. I has no affect on it whatsoever. This has been thoroughly debunked long ago.

If you use this app AND enter all those commands in a terminal window your battery life will double again. Do note though... this only works when typing the commands with only your left hand. Make the mistake of entering it all in the usual way and you will have no benefit at all, maybe even on the contrary... If you do, just take out the battery and shake the phone for at least 25 minutes. Put back the battery and spin around three times. This is a hard-reset for the battery stats, only necessary in case of an emegency.

With these tips my battery lasts 9 days with a screen-on time of 18 hours at least. It... is... genius..!
