[Q] weird charging reading !!

Recently a friend gave me his i9000 to check why his device always shut off suddenly. It runs stock GB . The problem is, the battery is charged but without showing any warning or low battery message , the device just turns off . So i exchange battery from another i9000 and saw, the phone works fine !! And the battery i got from the faulty i9000 and put into another one, bingo....that phone too wont turn on. So the problem is , that although, the phone works just fine, and battery will actually charge, it always shows the battery is charged 100 % !!! Always !!! I have installed CWM, tried at least three different kernels, and roms. Same result.
Does anybody can tell me , why this bizarre reading and why the phone and also every other battery widget show the it is charged 100 % while actually the battery is less than 10 % charged !!!

The battery is 90% at fault.
You should buy a new one

sorry mate, i might have confused you with the question. The battery is good, i tested on other galaxy S and that other phone, read battery charge level accurately . But the problematic phone, always shows 100% charge for every battery !!! So after a day or two, the phone should show low battery , but instead it just turns off, even than it would show battery is full !!!

To OP then mate the phone hardware may be at fault. I'm not sure though as i've never heard of this before
Good luck

Sudden battery drain when at 10% and below

Recently I noticed sudden battery drain when 10% and below. It takes a couple of minutes while browsing or watching youtube battery goes down to 4% and then in a bout minutes goes down 1% and off. I am not sure when it started but my guess after JB 4.2 update. I am on three UK network.
Thanks

Don't know if it would help but you can try to calibrate the battery (actually the displaying of the percentage).
Charge your battery until it's full when the phone is on.
Disconnect it from charger.
Turn phone off.
Plug in charger and charge it until the LED turns green.
Disconnect charger, turn phone on and use it as usual (my desire needed a full discharging and charging cycle after that)

That's what I was thinking battery display might be off the rails a bit.
I will do it on the next charge then. Other than that battery does great job. 24h+

I get this aswell, on android revolution 12. It goes from 8% down to 1% and bam my phone is off. Really annoying

This exact same thing happened to me earlier today (ARHD 12.1). Very annoying. Is it a rom thing, or a battery calibration deal..?

i cant be sure, but it happened to me one time, so i use and app from playstore to calibrate the battery, and now it is ok,

Mine does the same thing, but it quickly goes from 5% to 1%. I assumed this was a normal feature to prevent the battery from draining completely, which is something you usually don't want to let happen. If that's the case though, HTC should have taken that last 5% into consideration when calibrating the battery.

I suggest you all should try that calibrating method and if that won't work, it's probably a defect of your phones

Has anyone else had any success at all with this
I'm running 4.3 GPE rom and I get excactly the same thing here, I don't think I had this before .... I've tried recalibrating the battery, doesn't make any difference, so frustrating.....

In your case I think it's just a calibration issue. I personally had the same issue with ARHD but it settled with 5-6 charging cycles.

S3 Mini Battery

Hello . This is my first post here. I am having a problem with my battery. i recently bought a new one with 1700mAh,is a compatible one. now the thing is i left my phone to fully charge but is charging only to 89% and stops. my guess is that the phone only see the 1500mAh and the rest of 200 cannot. is there any way to make the phone charge to 100%? Thanks in advance!

i too have a 1700mah battery from the Ace 2 and it works like a normal 1500mah battery would. the first time when i put it in i shut down my phone completely and left it charging for 16 hours (although it did have 50% out of the box). Another thing i learned is that it's better to charge Li-ion batteries when they are below 20%, because they have a limited charge cycle (about 300 charges i think) so when you charge it from 70% to 100% it counts as 1 charge. i used to charge my original battery like that and only lasted 7 months (then my phone restarted randomly, couldn't turn on when actually having more than 70% battery left (the indicator said the battery's dead, but when i pluged it into a charger and turned the phone on it had more than 70% left) !!

so is there any way to make the phone see the 1700mAh?

Does your new battery 3 or 4 contacts? The original batteries have 4 contacts. I think that by the fourth contact phone receives information about the charge, and if the new battery does not have that contact phone does not receive charge Information so it approximates.

what's your 1700mah battery brand and model ?

the battery have 3 contacts same as the original. also the brand of the battery is Andida for samsung I8160 but is also compatible with my s3 mini.

ok i've got the same battery and the only advise i can give you is to charge the phone 16 hours non-stop and see what happens (better be turned off). that's what i did when i charged my battery for the 1st time.

Try to calibrate it manually. Charge the battery to 100% then with a root explorer go to data/system & delete batterystats.bin file & then unplug the charger.

I think that clearing the batterystats.bin file won't do anything, cause it just stores the info which is shown in the battery usage window in settings. And every time you charge your phone it generates a new batterystats.bin file. Not sure though

I did that and still from 100 to 90 in a few mins. I read somewhere that this is because all of the background apps but it still lasts a day with normal use (a little games, little browsing, a lot of listening to music and a few calls ) so it's no problem for me.

Battery problem

My phone got weird battery problem
My phone is 2 yr old & battery replaced last yr
S Off using custom rom insertcoin senseven artmod
I think physically battery is ok
Problem is phone shows battery discharging very quickly
after that what I do
reset battery stats by power off or auto shut down by low battery then holding vol up & power button screen on till phone off again then start phone again it will shows increased battery %
For eg using phone for 10 hrs with 1 hr screen on time it discharge 100 to 0% then I reset battery stats & start phone again it will shows 65% battery
2 nd thing if I'm charging phone it wether phone on or off (let's assume 35% ) it's % not increased but it shows phone using more power after some time it will shows less battery (15%)but in reality phone is charging after resetting battery stats with above method it will shows correct %(55%)
I tried these methods to correct it
Flash stock firmware again unsuccessful
Flash stock ruu again unsuccessful
Also tried vol up + vol down + power button holding for 2 minutes to battery stats reset
What I should do ?
I count manually battery life it's above 24 hr with screen on time of 2.5 hr

Did you re-downloaded your apps after flashing the ruu or you have tested the battery directly after flashing the ruu? (to make sure none of your apps or settings is draining the battery).

Battery is not drained

My problem is I have to restart & reset battery stats again and again to use 100% battery life I have to do it 4-5 times

What about your apps? Like @alray asked. Have you tested with just the barebone stock rom with no apps installed?
I had a similar issue a while ago it turned out to be "Gsam Root companion" after removing the app my battery percentage returned to normal.

Err! Strange could be battery problem but it's weird how clearing stats cures it temporarily.
Have you tried resetting USB host mode with Vol up+down + power for 2 mins?
Maybe charge to 100% in all modes (on, off and in recovery) wipe stats reset USB host mode and reboot and monitor.

Whatever I do it always shows decreasing battery % but after battery stats reset it jumps to higher value
Even phone is off & put on charging battery shows decreasing trend but after reset shows correct %
Totally pissed off

This is latest drawing uhhh !!

I think your battery is going to die soon. Most likely some of its blocks are complitely dead, that's why it shows that kind of stats

That will be good at least I won't have suspicion to change battery or not
But how it possible to have 24+ hr battery life + 2-3 hrs SOT ?

Did you try to run your phone without rebooting to see how much it will last? Also, did you try another charger? Judging from your screenshots my guess is your battery is dying, but that would mean you couldn't get that much off charge and SOT to save your life. My battery is still pretty good, and I get just over 3 hours SOT and 36-48 hours off charge

ok let me explain screen shot
Anyhow I charged phone to 100% start it use it for 14-15 hr with 1-1.5 hr sot it goes to 0%
switched off or auto off
not charged
Battery stats reset with vol up + power button for 20 sec (it shows green HTC then goes off again)
Start phone again it shows 60% battery again (not charged )
Use 7-8 hrs with sot 1 hr approx
Goes to 0% again
Repeat process again shows battery 30-35% again
So this is screen shot history

I understood your screenshot. So, every time your phone shuts down, you do the reset thing, right? I would like to know what happens if you just try to turn on your phone after it shuts down. No reseting, no nothing. Simply try to turn it on

That's a lot like my old Xperia X1. Turned out it was charge regulator issue. You might want to look that up. If I remember correctly, Xperia had that regulator on its motherboard. I changed it and everything was fine after that. I think M7's charge regulator is in the battery, so we're back to faulty battery. But that's just my opinion, you might want to monitor charging current to see if your phone is getting correct charge current

I have 3 HTC phones in my family I use their charger randomly
My sister's HTC One m7 battery is fine no issues
I think my phones motherboard can have some issues as in warranty period it's battery changed 2 times so it could be !!
I got confused as after 1st battery replaced I hard brick phone & HTC changed motherboard after 2 months of that battery replaced again
Now I don't know what it is ?
I wish if battery is faulty it should dead asap so I can replace battery

Well, it could very well be motherboard issue too, but that was my last resort as it means you're pretty much screwed if your warranty expired

If yes where motherboard or any other chip like charging usb ?

Rooted/Flashed: Battery issues

I've tried to fix this on my own, to no avail. Whenever my phone gets down to 50% battery life or so, it shuts off. Then, when I charge, it says 0% and will charge up to 100%, then shut down at 50%. It'll shut off around 30% occasionally. I've tried different ROMs- currently on Rapture 3.1. I've tried various battery reset programs- nothing has helped. What now?

Definitely a bad battery. I use Anker batteries and they works great. You can buy Anker battery set for around $20 on amazon.

I purchased a new battery (Samsung oem)- received it today, and put it in. Charged it to full, used it a bit, and at around 50%, my phone shut off. Any other ideas?

Though it's highly unlikely, but did you make sure that you didn't put old battery in your phone instead of new one ?

Battery Cal seems to have solved it, and is also obvious when I think about it.
