Usually if you use this, and you don't see an increase, it's because you phone is already working at max capacity. As you say you are pretty skilled, so that makes sense that you keep your phone working correctly. :D

Last time i did this my phone became hot as hell... Dunno why but it did. So now when i flash a new rom i just fully charge until 0mah in the current widget and then use this app to erase batt stats. That's it

On another note when the voltage in this app reads 4199, the maH in the current widget is still 30 or something...

Why is that marosige?

Leave ur phone off completely during charge and I won't get hot. =) the hea is due to background apps running. Which means either; 1) ur chargng and usin phone. Or 2) your phone is NOT going in idle when screens off. (Use spareparts too check)

I have a quick question. I have been using this app since I started flashing and I love it. This may have been answered before but I thumbed through 80% of this thread and didnt see it. But, I just bought a extended life battery for my samsung galaxy s T959 vibrant, will I be able to calibrate it with the same accuracy as my original battery? Or are the phones programmed to only read the battery that is furnished with them when you buy it? If so is there anyway I can change it?

Thanks for any clarifications.
[Android Apps and Games] CrazyTurk42:
I can't get 4200:(
[Android Apps and Games] bobbyphoenix:
That's more than enough to use it.

I only get to 4160. 4200 is industry standard. The phone cuts it off before so you don't overcharge. Staying below 4200 will actually prolong battery life.
[Android Apps and Games] Software Guru:
Will give this a go
[Android Apps and Games] jawz101:
I guess I'm confused but this seems like it would just create the same battery stats that it initially had. If it thinks your battery is at 47% on the old ROM, you flash a new ROM and it says it's at 47%, wouldn't 100% mean the same either way?

I've never looks at the battery stats file but I'd think you'd use this tool except once it reaches 100% leave it on the charger for 15 minutes to an hour more, then wipe and unplug.

Since, as you say, Android/the battery will never let the battery fully drain wouldn't the goal be to extend the maximum of what a file on the phone considers a full charge?

Skimmed through this thread and some people cannot get their battery to 4200mV. Is that normal then?

I've fully charged my phone until CurrentWidget showed 0mA and then pressed Battery Calibration. Done it twice already and mine just stays at 4187mV. Normal?

There are many factors involved, but long story short, yes it's normal. Anything in the range of 4156 to 4200 is good to go.

Hi battery calibration gurus -

I'm running an Optimus 2x (O2x) and have been through two calibration cycles, with 3 or 4 days between each cycle. I made a full post on the O2x forum HERE

Basically, I reach full discharge (0%) and shutdown at ~3450 mV, and this has been consistant each time I've done a full discharge. From what I'm reading in this thread (have read through end to end), full discharge should be ~3200 mV? Does the shut off mV level vary between phone models/manufacturers, or is my phone shutting off prematurely?

I don't really want to do another full discharge as it's bad for the battery; At 30% charge level, I get a reading of ~3700 mV, which seems to be consistant with the phone shutting down at ~3400 mV again.

I'm running stock firmware - is it possible that the O2x has a custom batterystats.bin file, and that removing it and allowing froyo to recreate the file is less accurate than the original batterstats.bin? I'm finding that battery life has been worse than before my first calibration (with the original batterystats.bin file).

Thank you :)
[Android Apps and Games] mochamoo:
In the last week I noticed something interesting. I flashed back to froyo to get the gingerbread update into my droid x (was running a gb leak). During that time Battery monitor widget showed 4230 when it was fully charged. Now that I am back to gb the max is also back to 4171. Can't get it to go higher. Battery life is great either way. The numbers don't seen to be telling the whole truth here. :)

[Android Apps and Games] bobbyphoenix:
Quick question. I know you say to let the phone fully discharge after calibration, and then charge it to 100%, but does it matter if I shut the phone off, or reboot it during initial calibration, or does the phone need to be on at all times until it fully discharges?
[Android Apps and Games] DanteGR:
No i don't think it matters mate. It is also not necessary to let it fully discharge after calibration. I have done it both ways with no noticeable difference.

[Android Apps and Games] marosige:
As the app says it's not necessary. I usually drain it to 0% then I plug it in, turn it on and charge it to 100%.

Question: I have fully charged my phone, calibrated while plugged in and let the phone drain to 0%. I am now charging with phone off and waiting for it to be fully charged to 100%. Should i leave it plugged in when i boot it when its full or should i boot without being plugged in?

i have three batteries (two 1400 mAh and one 2400 mAh), how do i calibrate them?
[Android Apps and Games] marosige:
How often do you change them?

I've got one 1400mAh original and a 1800mAh extended one. I use the extended but when I travel to somewhere and I can't charge my phone I switch them. It happens usually once in a month so not too often.

I calibrate my phone every time I put in my extended batt.

If you change it every day I think calibrating can't help you. But otherwise I suggest to calibrate when you put in your main batt.

**RESOLVED**

took battery out for an hour and put it back and it's working again.
[Android Apps and Games] marosige:
It doesn't really matters. You can do it both ways. In version 1.0 I suggested to plug it off before but someone told me that it's better to calibrate, then plug off.
[Android Apps and Games] bongo1:
Thank you for your app, i know it doesnt do anything special that can not be done via other methods but this thread has helped me to understand the way the calibration works.

I have a few questions.

1)can anyone explain this behavior please?

- charge at 100% 4207mv plugged in, unplug nothing changed.

- immediatly plug charger back in and its 99% mv 4137

- within few minutes its back to 100% 4207

- unplug its at 100% 4207..

- plug it back in its now 99% 4155..few minutes pass its back to 100% 4207

- unplug plug back in its now 99% 4170mv.. etc etc up to 4196 with this process at the moment?

2) How does calibration work with an extended battery? im using a 1800mah instead of stock 1450mah. Calibrate the same way? and let the android system work out when the battery is actually dead? should the % meter be accurate after a few days based on the new accumulated stats?

Thanks

[Android Apps and Games] RaymondPJR:
Battery Calibration

I'm using a Gingerbread Rom and Android has changed the way that charging works in Gingy. When you reach 100%, the battery will automatically start to drain. So you can no longer leave you phone unattended while charging as it will discharge if you don't pull the plug at 100%. Some have gone to sleep only to find they have little to no charge (dead phone) in the morning. It also makes it difficult to bump charge to a full 100%. I can now only reach 99% and 4191mV, no matter how many times I try. So, I'm not calibrating at a true 100% anymore. Does calibrating at 99 or 98% mean the app/phone thinks that is the new value for a 100% charge? I'm also wondering if physically deleting the batt stats then charging as high as I can will give me better results. Am I worrying over nothing?:)
[Android Apps and Games] DanteGR:
I'm on a GB rom my friend and I cannot reproduce what you are saying.

I leave the phone to charge overnight and when I wake up I always see the charge on 100% and the mA to 0 (4199mV maybe 1 or 2 times it was 4194mV).

[Android Apps and Games] marosige:
Calibrate your phone, use it normally. When the phone turns off(reaches 0%), plug it in the charger, turn it on and wait till it charge to 100%

You don't have to uninstall my app after that.
[Android Apps and Games] marosige:
I will write it to ny suggestion list and try to put in to the app :)
[Android Apps and Games] marosige:
You got that because the sensors are lieing.

When it reaches 100% it turns off the charging and wait (because of safety). When it's about 90-95% it turns back the charging.

It says 100% even it's on 97% because it would look strange if you would leave the phone in the charger for 24hours and it would be on 97% only. Thats why a lot of people report me that when they unplug the phone, it drains to 95% really fast. It was on 95% when they unpluged it. But the android system said 100%
[Android Apps and Games] DanteGR:
Yes but mine NEVER gone from 100% to 95 or 97% quickly mate. It decreases gradually as it should

How to Caliberate Two 1230mah batteries

Dear OP and Others,

I have two 1230mah original batteries and switch between 2-3 days. How should i caliberate these two batteries?

And when i charging my DHD with it turn on, the numbers always stop at 1199mA (for both batteries) then it will stop there no matter how long i keep it plugged in. Is this normal?

(So if it's 4,124 I will multiply and get 4124 and not 4)

In the next version there will be a profiler option, so you can change profiles and have 2 or 3 batterystat.bin files and the app uses the correct one.

I know that I allways promise things and there is no updates since the 10th of April, but now I have to work on a different project. But I have great ideas, so when I have time I will make them!

I don't know why. Both methods do the same thing. My app should be better because it's working on phones with the original recovery IMG, you don't have to reboot to recovery or buy the app: Root explorer and it shows you the voltmeter too.

If you want to calibrate the phone in the best way:

Install currentwidget, place the widget to the homescreen, plug in the phone, wait till the charging current become 0mA, then calibrate the phone with my app.

Run out of battery and then the phone is dead. I don't think this is related to the calibration app. I would try to do two more things before going to a service centre:

- Try charging the battery with a battery charger, without the phone, or alternatively try another battery which has charge. This because It is possible that either your phone is not charging your battery for some reason, or your battery has died, not your phone.

- Try to put the phone in download mode with a USB jig. If it works, it means your phone is not dead.

Hey

Do I have to reboot the phone after running calibration? Also there are a lot complicated guides on how to calibrate (e.g. http://xdaforums.com/showpost.php?p=15450518&postcount=3 // http://theultralinx.com/2011/07/calibrate-androids-battery.html). Are they really neccessary or is it enough to follow the instructions in your app?

Also when draining the battery until the phone shuts down (after deleting stats), should it be used normal or can I just run some applications to use up battery fast?

Thanks!
[Android Apps and Games] XuserJM:
No, it shouldn't be necessary with a reboot since only the stat.file is erased and os creates a fresh within a short time.

Regarding the method of draining the battery... I have no evidence to back this up but I believe that I see a overall better battery performance if I choose to drain with normal use instead of pushing it.

Regarding the other guides I am blank...
