Hello everyone for the last 3 days this battery calibration has been eating me up with milions of questions so i got perfect idea of what it is and why its important and why my battery needs to be calibrated . till today that i installed an app calls widget battery pro that can monitor your battery behavior and all and as i was watching my battery charging to full i notcied something in my opinions not right , which was the max mv cap my battery got as it hits 100% , my device is a galaxy tab s T705 with a 4900ma battery and here in this screenshot " http://cubeupload.com/im/1HP4in.png " you can see the max mv it got to was around 4324mv is that the battery mv ? or the mv thats going into the battery while charing it , i mean if thats from battery then my battery did not hit it max cap before hitting 100% charge which is when the charger adaptor stoped charging the battery . yes im using the oroginal charger and cable and everything and my battery doesnt show any funny behavior at all during usage i just wana know if thats what i think it is and i need to calibrate it or not to hit it max mv thanks everyone
let's please post only ONE thread or post per issue. Closing this up and we'll let people answer here:

i ask this because my battery stats have gone dumb dumb on me. first i had a 40% instant drop when rebooting and since 62% charge on my phone Battery Life how been showing 4150mV. it may fructuate 50mV (i think it keeps topping battery off and then when it goes down a tad i tops off again ).
So my question is then is my battery already fully charged and my battery % is off and if so why would it keep slowly going up when the mV's are no longer going up?
fyi i trust this battery widget. used it in 3 phones for 2 1/2 years. hasent update recently either

When your battery is fully charged it is generally around 4200mV. It seems like your battery is not calibrated. I recommend the battery calibration app. Search it in the market. Very easy to calibrate. Just charge till its at 100% and close to 4200mV and then hit calibrate.
Also, to monitor your battery stats (voltage, %, mW usage) I recommend the battery monitor widget. It shows graphs of your mV as well as your battery percentage over time.
Thanks bro, I apreciate the indepth answer. I thought it was 4200 but I gotta be sure u know
Hi, sry for my english=(
When i charge my battery its normally charge to 80% and then becomes 100%.
Try calibrate battery but this doesnt help. Also try another roms and kernels.
Is it a battery issue?
U can buy new battery from DEALEXTREME.com
so its the only way?
Try this.
Charge battery to full. Leave plugged in, Turn off fastboot in power settings and shut phone off. Light will turn orange again and let it charge til green. Boot into recovery and wipe battery stats. After this let the battery drain as low as 10% before recharging to full without unplugging. Do this a few times over a few days. If you don't get more accurate percentages after this then the battery could be messed up.

thx i will try.
i have the exact same issue. i have done battery stat wipe..flashed multiple roms over and over with full wipe and all that. battery charges up to 80% then the LED turns green..and stays that way till it reaches 100%. it jumps from 80% to 100% in just a few minutes.
battery jump
I wouldn't worry Lendlord mine does the same (see attached pic) you can see the green line jumps up from 80 to 100 but doesn't jump down from 100 to 80 under use. The picture is taken from Battery monitor widget, it's a great app which shows mv, ma, % and temp and even keeps a text log of what ma drain there has been allowing you to monitor battery drain while you're using your phone or while it is sleeping.
Here's a great guide aswell of how to ensure best battery life by memnoc:

so thats mean that some battaries have the same issue=( And there is no solution for it...
HTC failed again...
first GPS and now the battery. Bad, very bad!
And one more request.
Can someone post your current widget log?

I have the same thing happen to mine, i think its because you've let your DHD die due to low battery levels and that damages the battery which i think causes this problem
..letting the phone shut off because of a completely discharged battery is NOT good for the lifetime of Li-ION batteries.
The battery could be hurt and the amount of mAh the battery is able to store might be lower after.
Also trying to 'pump' the battery to fully charge by connecting / disconnecting while the phone is down is not a good advice because li-ion batteries also don't like overcharging.
To be sure that the battery is fully charged due to its ability it is sufficient to let the phone be conectet to charger or usb overnight.
Android uses the voltage of the battery to estimate (!) the % charge value.
Android supposes the battery is fully charged when it enters the voltage of about 4.2 Volt which is the charging cut-off voltage for li-ion cells.
Now when charging again the conceded voltage is reached more quickly than estimated by android, so the system is 'surprised' of this rapid charge and changes the % value to 100% because the conceded voltage is reached more quicklyy as supposed.
(Try to fill a 0.5ltr beer bottle into a 0.33 glass)
This is the normal of aging for li-ion batteries.
Consider for yourself if it's acceptable for you or if you should by a new battery.
by the way... be careful with cheap china batteries for 10$.
Offers with exaggerated values (up to 1600mAh) will mostly keep their promises
only for the first two or three charges only and will than fall back to 800 mAh or even less !

Pudel
Yeah...
My battery started to do the same thing for a week or two. It will charge to 86% then it jumps to 100%, saying it's charged.
This is normal afaik, nothing to worry about.

actually，it's the problem of your rom , in the framwork.apk . unzip it you will get a lot of battery icon form 1%to 100% in the res file ，if it made mistake，that 'your problem. you can go to uot kitchen to coustom it again.
Nope!
I've solved my problem. I've bought a new (original) htc battery, and the new one works great. I haven't reflashed the rom, or made any new modification. Just added the new battery.
So, yes, it's a faulty battery.

Have a good day .. Tech at XDA
My Samsung Galaxy Gio Battary Charge quickly and drain in a similar style. I buy new battery but situation remain same. Battery Stat from 8% to 15% to 30%...55% and some how stop on 80% in just 15 to 20 minutes.
Please help.. Is it battery problem or charger (I buy new charger also) or some kind of IC circuit problem.
Thanks in ADVANCE

Drain your battery to 0 percent then do a complete charge from 0% to 100%
Worked for me.
I have the same problem.I tried two different batterys and from both i get the same result.I think it's a problem with the sensors,when it reach 100% stops charging but in reality isn't charged at all.

Did you recalibrate the battery?
Here is a link to an app in the google play store
http://goo.gl/xRHjp7
I discharged it yesterday and then it charged completly in 15 minutes.I see in the app's screenshot that at 66% he has 3882 mv.On my phone at 100% it shows 4mv.

Mv is milivolts and mah is milliamphere. they're different. Youalready hit your max mv at 4324. Anything higher will make your battery bloat or worst. Explode.
Try using battery monitor widget, you'll see the exact mv and mah values while charging. It will show you that once the mah reach 4900, your charger will cut off and your phone will notify you to disconnect it
hey mate ty for your respond I however got that all sorted out >< it was all my bad I can now easily hit 8hrs screen time with a full charge and that tells me my battery is more than okay and yes now i understand the difference between mv and ma thanks a lot years I do use a battery monitoring widget and when my device is fully charged it stops at 4900 thanks for everything it was all a misunderstanding cheers

Hi.
I recommend the free version of GSam Battery Monitor, enable the alarms in the settings, this is the best monitor i have see, and i have tried them all.
It save my 10.5" from damage or worse as the battery temp alarm went off during the night when i was sleeping, some misbehaving app, when it was in it`s case supposedly sleeping.

John.
I reported already on the official asus forum regarding this issue, but I want to read people's suggestions here.
There is a missing capacity around 200+ or 200mAh + where it says battery is fully charge @ 100%.
The uploaded images as you can view, is from zenfone 5 and zenfone 2 screen shots, where in 100% fully charge of zenfone 5 capacity is accurate, while on zenfone 2 there is missing capacity.
See attached images.
you may check yours, no need root.
Using ASUS File manager, navigate to root of internal storage, (must uncheck "Hide system files" first on the 3 dot menu) then navigate to sys/class/power_supply/battery/uevent, you may view the file by opening it with HTML viewer.
Many or majority had this bug.
Any explanations here or comments?
This could be the very reason why battery drops fast from 100% to 90%.
This might also be linked to my problem- my phone dies when it gets to 25-39% battery.
Is this file editable?
Yes it is, do a full charge and view your battery capacity.
Now my phone goes from 100 to 0% in 40 minutes. At least it reaches 0%... battery behaviour is erratic
Hello
My firmware version is 2.19.40.22 WW, which I updated from asus website.
Earlier phone was working fine, but after update battery charges from 80% to 100% in just 2-3 minutes & discharges till 70% very quickly. I didnt note the earlier version of the device.
Please anyone guide me which is the best firmware version for ZE551ML, 4gb/32gb version.
Thanks.
Latest firmware version 2.20.40.59 also has the same issue .
How to fix this issue???
Anyone???
$umit
Not only 200...but im losing 300 ...
Mine seems to operate normally but shuts down at 40%
Try to check your capacity.. Still this is not fixed but was reported earlier.
Can battery calibration have anything to do with this? I just checked mine and its at 3000. (That's the correct value, right?)
I do remember "calibrating" the battery when I first bought it. The battery was flaky when I was using it for the first time (phone died on me at 32%), but after some calibration using apps and some specific steps, my battery is better than ever.
EDIT: Okay I take that back. I checked again and it's 2700 mah at 100%, shame. If there's a way to fix this, it would be awesome. This seems to be a miscalibration as the capacity shows 3000 mah. Or is that 200 mah a reserve or a buffer so you would not totally drain the battery?
EDIT 2: Tested this out some. Seems to be a hit or miss. Check my answer below.
Oh I just checked it and more than 1000 is missing :|

You're battery is not at 100%, you're at 44%, so of course it's going to be low. Charge to 100% then repost your results.
Any solution yet?
I am loosing 301mAh. I already calibrated it, but problem still exist. Is there any solution yet?
After reading about jump charging, battery calibration etc. I decided to do some "test". I plugged my phone after consuming only 2% of battery and charged back to 100%.
And it seems that the POWER_SUPPLY_CHARGE_NOW value changes everytime you charge your battery to 100%. I don't know why this happens or what this means. I do know that you can "increase" that value by doing what I just did (charging to 100%, let it sit idle until it's at 95% or so, then charge back to 100%).
EDIT: POWER_SUPPLY_CHARGE_NOW value seems to change each time you charge your battery, regardless if you charge it to 100% or not. Check my comment below.
Will the battery charge till 3000 by this method?
Every time it needs to be done or this can be done once and than calibrate the battery?
It seems that the value of POWER_SUPPLY_CHARGE_NOW changes, not only when you charge to 100%, but each time you plug your phone. Mine just got off from charging at 91%, and I computed what would be the 100% value of POWER_SUPPLY_CHARGE_NOW and it's 2819. I've had different values each time: 2700, 2701, 2644, 2688 and now 2819.
I'm skimming through articles and posts about this and there seems to be a bug about x86 processors reporting battery status? I'm not sure about the whole technical stuff, so hopefully someone who understands this would chime in.

Haha wow, so your ZF2 somehow managed to go super saiyan!
Maybe that's it? Maybe all this does not mean anything at all?
I've never had any battery problems with the ZF2 so far. I charge by 15%, take it off charging at around 96%. I make it a practice to leave a charge higher than 30% when I will let it sit idle overnight (luckily, quickcharge makes this easy). And with that I've always been satisfied with the battery life.
Hi All,
I had the same issue with my phone where I'm losing around 1200+.
I charged my phone using my Nexus 7's charger and it somehow resolved the issue. I charge it from 40% to full and it now shows 2900+.
It might be with the excessive used of quick charging.
