[Q] phone showing wrong battery charge

hey guys,
i got a little problem with my sgs: it shows me that the battery charges itselfs if i don't use my phone for a little bit (for example: i play half an our lane splitter and battery goes to 23% then i leave it for an our in standby and when i come back it shows 28!)
I hope the screenshot might can help you.
P.S.: Sorry for my bad english

...

Did you also try battery calibration app from market?I don't know if it does anything else than clearing battery stats, but I think it's worth trying...root is needed though.

I have tried it with the app and with cwm. Both didnt help.
I think both do the same thing.

You can try to do a wipe battery stats in recovery after you have done a full charage.

..

Maybe just your battery is already death, try another battery if you have a possibility.

..

I have this issue too. I think it estimates battery and when it is left to idle it gets more accurate. I notice if I continue using it it still dies but idling saved battery..... could show battery percentage according to usage ? ( although I'm guessing here)

[Q] battery gauge problem

hello
after flashing a few roms, my battery gauge is messed up.
the things i noticed, when my ace turns off deu to low power. the gauge shows 0%.
but when my ace shuts it self down and i plug in the wall charger. the battery gauge shows me a percentage around 75%.
the things i have done to solve this problem is deleting battery stats by cwm and a calibration app nothing did solve the problem.
also i have let the battery drain to zero and then charge it up to 100 and let it drain to zero again. also that didnt solve my problem.
so i flashed back the stock rom by odin. also not solving the problem.
is ther another way to solve the problem

Get a new battery.:thumbup:

The problem is not with your battery. It's with the battery notifier in the ace. It works well for a time and then goes absolutely crazy. Whenever your battery gets low, about 10% for example, connect the charger and charge blindly for 3 hours. Don't worry about the 100% notification. Try your battery now. It should be fine now. But if you're using battery extender kernel, there's a bug in it that brings down the battery for 50% in a short time after using.

i`am on stock gingerbread, the phone is about two years old. i also noticed that when i turn of my phone and pull the battery out for about three minutes en then put it back in the percentage is higher. so i do think that the battery gauge is messed p but when i use a calibration app to solve it, it gets worse or doesnt change. when i use code *#*#4636#*#* the status of my battery is good. im thinking to buy a new battery but i doubt that it would solve my problem.

Calibration is all fake. Do as I said and you'll definitely witness the results.

Hi, I have the same problem with the ace of my wife. When I charge it, it says 100% after 10 min charging !
And when I use it not charging, it drops down ...
I try to let it charge longer, but is that sure that the battery continue charging even if the notifier indicates 100% ?
I'm on [ROM] CM7.2-DEMOCRACY FINAL EDITION .. is there also a kernel to change to help ?
Thanks for your answers, by default I will let it charge for 3h.
PS : is there an app to check the battery life ?

in dialer u must enter the code *#*#4636#*#* there will appear 4 tabs there is one for battery tap it and you wil see the health of youre battery.

Guys, forget about battery level notification, etc. Any app doing so would collect the info from the android itself. Just do as I said. Everything will be fine.

I've the same issue. I charged it for 3 hours, it's not fine, it goes to 50% in about 15 minutes, and when I reboot my Ace, it drop to 15% !
I noticed that when I turn it off and charge it, the green battery indicator is at 80%...
Any idea ?
I tried differents ROM such as CM10.1 CM10 CM9,PAC, same issue.

I bought my wife a new battery @2000mA and she lasts 2 days now, so the answer seems to be the battery-life ...

CM 9, 10.1,PAC consume battery like hell, but not that much also.
If there r such huge drops that too after charging the fone for 3 hrs then i guess there is a problem with the battery.

Yes I thing the battery is dead, it's slightly inflated...

I too have the crazy battery problem, but funny thing is if i were to ignore the indicator and just use it from a 3hr-full charge till it dies off, i could achieve 2.5hours of internet surfing (wifi not 3g). To me this is good enough, all calibration fixes do not work for me. Any suggestions?
PS: I have the system time problem too with S'perience Rom, Eg. when i shut down the phone at 1pm to remove the simcard, after booting up the phone the time shows 11am. This happened to me more than 5 times this week. I dono if it's the rom or the battery that gives this problem. I dono about how it was when running stock rom because this phone does not belong to me. Any help is much appreciated.

Try a full discharge and then plug your phone until it is fully charged, finally without unplug it boot into CWM and wipe battery stats, finally reboot and charge it until 100%

[Q] Is this normal?

.. 1) That the battery level quickly drains from 100 to 96 after reboot after full, completed charge? And if I reboot it once more, it boots up at 96 with no additional battery drop..?
2) I got some kind of battery bug, because sometimes when I unplug the charger after full charge, my battery is draining to fast, and to fix this, rebooting is required. Here comes the problem.. It is like the phone got problem with proper % reading so, let's say that my phone is at 97-98 when rebooting, it starts up numbers as low as 91 procentage..
Is it something wrong at kernel level perhaps? I am on latest Doomkernel (V18) atm and rooted stock ROM..

I am using xperia z, observed similiar battery bug, although not exactly the same, in the previous 244 rom. When updated to the latest 2.67, seems that the battery bug is gone. You can give 2.67 a try to see what will happen.

I am already on .67 FW - rooted, de-bloated and tweaked for battery life. Problem for me is that battery drains a lot once it's on 100% and un-plugged, and to fix this, I have to reboot phone and then my battery sinks down up to 9% after an simple reboot.. This can't be normal, right?

I noticed that ages ago... and all i did was drain it and full recharge THEN drain to 50% recharge to 100 and repeated twice over and i aint had a quick drain since then...
People Say dont coompletly kill it but me being a "rebel" i did it anyway because i have insurance on the phone so i would just simply replace it same day =]

Are you using the original usb cable for charging? I once encountered similar issue like you but I found out the problem is because of third party cable/charger.

Not to 100%.. Battery level falls down to 97% after reboot, after complete full charge. Additional reboots doesn't drain the battery by 3% though. Strange as hell..

This must be something at kernel level that controls the battery reading, or so is the battery procentage non-calculated. Whatever, I hope this will be fixed.

Happens sometimes to me too!

No. Just wait some time, I think that battery needs to calibrate itself with charging. I tried CM11, in first it was awfull, after 2-3 charges it is becoming usable. But still CM10.2 and CM11 based ROMs are battery eaters. Try CM10.1.

Thanks very much for y quick answers ...i hope that it can to remedy the battery okey but i try too cm 10.1 ...thanks again :good:

Next time when you flash rom or even update to official firmware make sure your battery is always 100%, not 80, not 90 but 100%... I had problem with discalibrated battery cause i update from Ginger Bread to official Samsung Jelly Bean firmware and my battery gone crazy... Try charge-discharge couple of times as shut-down says... This problem could be a swollen battery too cause you say that your phone turns off when you are at 25-28%... To be sure that your battery isn't swollen, turn your phone off and make this steps:
step 1: Take the battery out of the phone.
step 2: Put it on a level (flat) surface.
step 3: Try spining the battery, if it spins freely than it's swollen, if it doesn't spin it's good and try this on the bouth sides of the battery.

Battery caliberation problem. caliberate using battery caliberation app or delete batterystats file

Discharge to 0%, full charge to 100%. And leave it some time (don't plug off your charger), maybe hour and more.
Type this in Terminal editor: cat /sys/kernel/abb-chargalg/eoc_status
And wait untill it says the real EOC reached.
{sent from my mind}
if I help you, simpe just hit the thanks button.

i was having the same issue with Carbon 4.4.2 build 3, i did this:
*Uncharged the phone until 12-15%
*Rebooted phone 7% battery (every time i rebooted i losted 5% no matter what)
*Charged phone good 4 hours and then ran Battery Calibration APK (battery Calibration was showing 4120mha)
*Rebooted left phone alone 15 minutes ran Battery Calibration APK again (battery now was showing 4245mha)
*Ran greenify, hibernated almost all apps except whatsapp (bug with that was launching Player pro instead)
*Disconnected phone went to settings/performance changed:
Cpu Governor to :Abyssplug
Minimum CPU freq: 200mhz, Max: 800, set on boot.
I/O Scheduler: Deadline,set on boot.
Memory Managment: Zram to 10%, Allow purging of assets and KSM, also 16bit transparency.
i had 100% battery from 1am to 5am (whatsapp, fast for facebook,player pro, traffic racer, heavy wifi, screen never went off) at 4:35-40 i had 57% battery, to 5am i was having 55%, slept til 11am from that on i haven't used my cellphone too much but i have 35% current battery...for me its okay since i alway have a backup battery.
Pdt: i owe you the picture im in my office and don't have an usb cable with me.

[Q] Reboot causing a huge battery drop...

I'm not gonna ask any questions about why batteries drop so fast because i figured that out. Now my battery's draining 1.5%/hour on idle. That's good. The problem is whenever I use my phone continuously for an hour or so, there would be a major significant battery drop when I reboot it. I tried waiting for the battery to recalibrate but it doesn't. Not to mention an average use would eat my battery by 10%/hour or more. Other than that, whenever I let my phone on idle until it's at 40-30%, the battery level suddenly goes to 1% when I use it and my phone would shut down.
I am using Greenify donation version, and Amplify.
