Recently I've installed the BatteryCalibration 'cause my phone doesn't turn on for a long time after installed CyanogenMod. After the installation of this app, I saw the mV level on this app, and my maximum always appears 3 or 4 mV.
Looking at the Google, various cellphones with Android, be they Android 2.2 or Android 2.3, have the 1000+ mV, and my aparell doesn't have this, have 3 mV.
It's normal? My battery lasts only four or five hours totaly, it's not use, it's use more sleep time.
PS: If I change the battery, my mV grows?
This is an bug in Ace, it doesn't shows right mV for the battery, you can find the right value in /sys/bus/platform/devices/msm-battery/power_supply/battery/voltage_now and it isn't an effect of battery calibration.

Real battery voltages should appear as 4200mv charged. Ace is screwed up at that by showing 4.
Also the Ace can't display accurate battery percentage, hence the big percentage jumps.

Are you on the stock vibrant firmware? If you are, there is nothing you can do, the battery icon just sucks.

2. There are battery mods to correct this

Canadian Telus Fascinate (Vibrant, with Normal North American 3G instead of AWS. )
Basically, Captibrant.
But I call it the Fascibrant, since telus calls it the fascinate but it's really a modified Vibrant.

"Battery recalibration" can cause the problem that you describe. I have written a technical description of this at:
http://dl.dropbox.com/u/12962476/Battery_Conditioniing/Battery_Conditioning.pdf
It is likely that clearing your battery stats and then rapidly discharging has biased your battery stat tables away from the reality of a normal discharge cycle. If so, that condition will correct itself over time (days or weeks). To correct it more quickly, I suggest that you discharge your phone completely and then clear battery stats as soon as you plug it in to charge. (That is, discharge completely, plug into charger, boot immediately, then clear battery stats immediately.) Then just use your phone normally and the battery stat tables will rebuild themselves over a few days according to your particular usage patterns. The battery meter should become increasingly accurate as the tables rebuild.
My stock battery is showing maximum of 1200mAh.
I would like to know how do I calibrate battery to go back to 1650mAh?
What's the correct procedure for doing this?
Thanks!
If u r using battery monitor widget for this u need to set the battery capacity yourself . 1200 is just the default value. U need to change it to 1650 in the settings

when fully charged the voltage shud be just a lil bit over 4200mV
i guess a picture is worth a 1000 words... have a look...
more pix for ur eyes ^_^
If your rooted, try battery calibration. Plenty of threads about, and varying methods.
If not, another battery, and if new, ensure charge fully, phone off, overnight, before first boot.

forgot to mention i'm running [Rom]Wanam v3.2 at that time, currently on v3.4, the dark extended areas is me at work where i turn airplane mode on due to serious bad reception at work... sync is on rest of the time for gmail/whatsapp/kakao other than that manual updates on twit and some news apps...
u can see the first jump in the first pic, that was due to me exchanging with 1st spare battery( got 4 + original batt= total of 5)
i dont know if its the phone and exchanging batteries thats causing such high battery losses at the end of the battery life...
plus yesterday and the day before battery goes crazy when it reaches 30-20% and when i go for a restart to freshen things up... the phone wont switch on thinking the battery is totally dead... i put in the new battery and its @ 100% ... switch back to the old battery to see where the 30-20% went... it wont start...
now im thinking... keeping 1 battery in the phone with a charge from 0-100% actually takes the phone all the way to 0% but exchanging the battery wont...
how am i supposed to use the full potential of the batteries...

been using this app since my old sgs, it sure works and have been using it ever since...
tho in the [Rom]Wanam ... install procedure says that its backing up the battery stats and this lead me to think that a batt calibration is not needed... or am i wrong to think so?
If you change batteries, all previous data will be irrelevant, and you need to calibrate each time. You can do things manually by installing battery monitor widget, charge to 100% AND until the mA reaches zero (Voltage spills be approx 4200mV). At this point, quickly delete battery stats (menu / stats /) and immediately unplug.
https://market.android.com/details?id=ccc71.bmw
Top help with monitoring, You can config the update rate and widget content so it shows mA, %, mV. Also have alarm when stops charging (if configured).
There is also an option for calibration, but I only use this method when done above first. Never discharge to zero, 1% min.

Thing is, what's the use of having spare batteries if this will happen on each battery swap and having to go thru calibration means having a charger nearby...
and by 0% i didnt actually mean 0 but till that 1% turned the phone off
if what u said is true, then i guess i need some kind of script to help and keep the batt data even after swapping.. based on 1 good calibrated file swapping batteries should start from a certain point even if the batteries do lose some of their charge but continue to moniter things as they were... i dunno if what i said makes sense... correct me if i'm wrong
Not really 100% sure, but sure I have not always calibrated after a battery swap in the dhd..The previous battery was calibrated and performing well, and the replacement would have been very close to 100% charge. I didn't notice any irregularities in the battery data, or battery drain.
So I suppose a good bat stats file should help the phone showing relatively "accurate" data after a battery swap, if they're both "conditioned" (gone through a number of charging cycles, not straight out of thre box)
Maybe I could be wrong, but based on past experience.

Have you tried different radios/modems for better reception? if your phone is struggling to get decent reception its going to use your battery.
You could try changing to 2G only in wireless settings. used to help me alot.

Hi there,
I know the maximum voltage is 4205mV but what is the minimum? When my battery level was at 6, the voltage was ~3,600mv which concerns me because I have a gut instinct that my phone actually has more juice but is miscalibrated towards higher voltages.
I saw the Ultimate Battery Guide and it mentions that before calibration, OP charged to 100% and had ~3,400mV. This means that despite his terrible battery life, he was still able to run his phone at a voltage lower than my lowest - and his was at 100%!
So what voltages are you lot getting when battery life is almost dead?
Any help is highly appreciated.
Thanks!
Wow, it's been 5 months and I forgot about this thread.
So...
BUMP!!!!
Glad u bumped this up I am at 32 percent and have 3792mv still I keep running g it down see what I get
Sent from my MB860 using xda premium
Ok at 4 percent I am at 3490
Sent from my MB860 using xda premium
I've seen voltage readings logged in Battery Monitor Widget as low as 3200 - 3300 mV before the phone shutdown automatically. The low 3400's are probably more common with a percent or two remaining.
DisableCriticalBatteryShutdown
(for Xposed Framework)
What?
Disables the Auto-Shutdown when Android detects a critical battery level
Why?
This is to prevent the auto-shutdown when you have 1% left of battery. It is useful for calibrating your battery by draining it completely, using Chinese Branded Batteries with terrible battery percentage detection or even lengthen the life of a phone with non-removable battery with terrible calibration.
Compatiblility
Not working on 4.3+
Tested only on AOSP 2.3, 4.0, 4.1
This project is abandoned, I will not add support for any other ROMs.
The App has no interface. It only shows a notification for the attempted shutdown (shown in the attachments)
Disclaimer 1
I am not responsible for any damage to CPUs, SD cards, Internal Storages, or other failures that happened after your battery became flat and your phone abruptly dies.
By choosing to use this module, you are fully aware that this can cause damage to your phone especially when writing data to the SD Card or Internal Storage.
Disclaimer 2
Lithium-Ion batteries should not be drained everyday over a long period of time. Doing so WILL decrease the lifespan of your battery. Calibration may or may not be a placebo, however, it really depends on how you use and what type of battery you use. If it has no effect for you on the first "calibration", please do not continue to drain your battery everyday.

1) No. Until your battery is completely dead
2) Yes, I haven't tested but it is compatible.
If it works, your phone will abruptly shutdown after receiving the "Blocked Shutdown X times"
If it doesn't work, you will see the shutdown dialog with the spinning wheel before your phone shuts down.

The side effect is allowing the battery to drain completely. Ususally used for calibration but if you use it everyday over a long period of time, it WILL decrease your battery life.

Lithium-Ion batteries are NOT meant to be drained. You WILL decrease the life of your battery (since it weakens the anode bars physically). Draining works for Ni-Mh batteries. Android calibrates your battery between 80 and 90% so if you have Lithium ion batteries, calibration is a placebo. Correct me if I'm wrong. :good:

Actually, if the battery metering chip (also known as the 'fuel gauge') is giving inaccurate results, calibration will make a world of difference. Here's an example - on my (generic Chinese) tablet, the meter often goes down quite slowly during usage, while voltage goes down normally (according to BMW). When the meter hits ~35%, the battery starts going down abruptly (~1%/second), until it gets to 0 and the tablet shuts down.
This doesn't mean at all that I have a flawed battery, since I am getting the same usage time as when I bought it (battery was flawed from the start? :silly: ) - the battery meter chip is simply inaccurate.
Thank you, OP, for this mod, it's gonna come in handy.

Removing battery stats is different. On a battery with a terrible calibration, it will not prevent Android from shutting down when it (wrongly) detects a low battery. This module disables the shutdown when you reach 1% and below. Long term usage of draining to 0% WILL lower your battery life. So use only for calibration

Thanks. I recently purchased an extended battery with twice the mAh as the stock battery but I am still getting roughly the same amount of time out of a full charge. I am hoping this will fix that. :good:
YES!!!
Looking for 1 of this for sometime...
Good job...
My phone seems to have wonky battery life, it will jump from 14 to 12 to 10 to 3 percent then shut down.
This should help immensely for calibration if it does work.
Will report back. Happy holidays ☺
