Battery meter stuck at 100%

In addition to my other issues, refer to thread http://forum.xda-developers.com/viewtopic.php?t=43272 (ERROR: ITWriteDisk - An internal error occurred), I have noticed that battery meter on my 8125 flashed to the the imate aku2 rom, is always at 100%. I'm unsure whether this will effect charging since when I plug in the charger, the led turns green immediately and stops charging, and I have had the device turned on for 4 or 5 hours disabling all the power saving features, leaving the backlight on, turned on BT and wifi, and its still at 100%... either its a great battery, or somethings screwy.

small update.
after about 5 hours the battery meter started to drop quickly. Although this is good, the problem that comes up for the first 5 hours, you cannot charge the device as it thinks the battery is full.
Am I the only one experiencing this?

same here.... after 24 hours battery meter droped from 100 to 94
bafore it was 90 after 24 hours
maybe they improved something.. thats why it does not go so fast as before

I think it is the fact that the new rom seems to be much better with power consumption. I am getting almost a 50% gain between charges due to my pattern of usage!!! Very happy!

I'm more then happy at the battery improvement, what I am not happy about is that if this is a bug (granted there is improvement), the problem becomes when charging the phone, so I have it for 12 hours, its still showing 100%, I have an offsite meeting the next day, and would not be able to charge the phone for the entire day, the battery will start to drop very fast since the phone thought it was fully charged, when it really was not... I'm confusing myself here, but I think you understand what I am saying.
Also, while my battery was at 84%, I did a soft reset, when the phone came back up, it showed 100% battery and refused to charge... this is a problem.

You might want to inquire about a replacement device or battery - in case it's not the sotware.
My laptop has this issue. It's always been on external power and somehow that's weirded out the control circuit telling the machine how full the battery is. It will read 100%, but it's actually at 75%. Then if I disconnect it, it will go down to 5% in 8 minutes. However, it will happily run for 3 hours+ on that last 5%. Similarly, if I hook it back up to the charger, it goes to 99% (leaving the battery indicator light amber) in another 8 minutes. Takes many hours more for it to get back to 100% (making the battery indicator light blue).
With any luck the control circuit will be in the battery (I believe it is), and the easiest way to check is to exchange your battery for a temporary new one and see if the problem goes away.

Agreed.
If you think your battery is stuck - just do this little test.
Turn on Bluetooth, WiFi, make a GPRS connection, and set back light at 100% and don't let them turn off or let the unit power off. The battery should drain pretty quickly in this senario.
I thought mine was stuck, but it dropped 5% in less than 10 min in this mode.

I'm not so sure its the battery.. another issue that I just noticed, is taht even though the backlight is turning off, the screen itself is not turning off after the designated time I set...... this is rather bothersome as if I forgot to manually turn off the screen.. it remains on constantly.

Even with my original Qtek 9100 EN ROM, the screen doesn't turn off - only backlight. If you want the screen to be off, you'd need to go to Standby, or use a third party utility to turn the screen entirely off.

Although lithium batteries are best kept at a full charge, they should be periodically drained to recalibrate the fuel gauge.

I was also having this problem but after about 2 days use it began to go down. My G3 device seemed to hang at 100% and drop quickly after it hits 25%. I believe this must be a hardware issue as I now have a G4 (setup identically to the G3) and it does not have this issue.

i am having the same issue but i believe it the battery because my phone 8 months old and if you read the battery thread it has all the same issues your having

Battery Accuracy Problem

Hi everyone, well when i charge my battery all the way to 100% its fine, i use the device as an mp3 player as well which in my case brings down the battery 10%, but most of the time my battery meter is not accurate, for example it will say 54 percent but when i restart the phone it will shoot up to 75 or something, it always does that, is there any hardware problems or anything?

Battery Trouble
Hello MimoG3
This may or may not be related, but I remember after restoring from a backup a few months ago and removing the battery prior to this the device battery meter was very inaccurate. After the restore, the battery extremely low warning came up because it thought I had 0% battery. Long story short, after a while I noticed the battery was not seated properly. So I took out the battery, cleaned the contacts, and put it back in, and it worked fine again. Try cleaning all the battery contacts. Google "Clean battery contacts" or something similar if you do not know how to safely clean battery contacts.
Also, although I have not had this problem that your are describing, try posting your rom and rom version, radio, device information, battery s/n if possible, and other device info should it turn out there is a bad batch of batteries or devices.

i have noticed when i restart the phone once in a while and when the battery is fully charged it will think its empty and shut off the phone, to fix that i take out the battery and it starts up again. also sometimes it freezes at startup until i take out the battery but that happens when i restart as well.

Leave your phone on playing music until it turns itself off because of low battery. Remove battery 10 seconds, put it back in and turn on again. Repeat until the battery is really empty and the phone turns off less than 5 mins after you turned it on. Plug charger, turn on, leave until fully charged. This should improve accuracy. Avoid removing the battery if not needed.

ive done something similar to that, i turned on the wifi, bluetooth and gps on so that it would drain the battery fast, then when it turned off i turned it on again with all those things off except the GSM Radio, then eventually it shut off once it stopped turning on i charged it all the way. it still didnt help

battery measuring is not really that much of an exact science
only way to tell the % is
when a batt being pulled current from the volts drop
the less juice left in the batt the more it drops
so the device measure the volts
and makes an educated guess how much juice is left
just after a reset the batt could very well perform a bit better
for a few mins voltWise

Did you remove the battery? The phone doesn't usually reset the meter if you leave it in.
@rudegar: No, most recent devices including HTC phones don't only use the battery voltage but count how much energy they use / charge to the battery. That usually allows more precise measurement, but can also sceww up if uncalibrated, and is really annoying as it doesn't want to use higher capacity batteries correctly.

[Battery] Strange anomalies

Hello guys,
I've messed around with OC etc. and I had to take out battery couple of times. After that some of my apps had reseted settings (probably sqlite db corruptions - it happens). Strange thing: after that my battery lasted for 2 days. Before that I was lucky if I got one day on one charge.
Latetly everything went back to normal and no more 2 days without charing.
I didnt installed anything new etc. Maybe market installed some updates - thats all.
Conclusion: something is f*cked up with our phone .;-)

I think it has to do with lg's battery drivers not working well. If you pull the battery (while the phone is running), on next boot the battery level is usually lower. I think that this causes the levels of the battery to be determined again. Normal shutdown looks like it's saving the battery level somewhere instead of determining each boot.
I've noticed one time after a nandroid restore the battery level was the same as when I did the backup. In this instance, I flashed a new rom to try for a couple of hours, then did a nandroid restore. If I remember correctly, it was about 55% when I did the backup, and about 25% just before the restore, afterwards it was back to 55%.
A while again I tried using this method (battery pull) to calibrate the battery. Using the pre #40 cm nightlies, you could boot without the battery in, using the usb charge. The method I used was to charge 100%, shutdown, remove battery, plug in to wall charge which booted the phone and inserted the battery during the bootup animation. After bootup, the battery level dropped to anywhere from about 95% to about 75%.
It certainly looks like to me that the battery isnt getting fully charged each time.
So maybe with your battery pulls you were actually recalibration you battery and getting a full charge, but after a couple of charges, it was back to normal ie not fully charged.

Huge problems with my galaxy s3 in the past few days.

Hello everyone!
This is my second post here...but I really felt like I had to take attitude this time and actually do something.
So my samsung galaxy s3 is acting so weird that I can't use it without something bad happening for one day.
So...first of all...my battery doesn't last more than four hours straight if, for example, I am listening to music.
It literally goes down about 1% every few minutes.
Also..there is something really weird happening with my battery even after it completely shuts down. Lets's say I am on 1% and the phone shuts off. After the screen goes black and I plug it in...the charging screen appears and the battery seems to be half charged. I open the phone again and it is already at 45%. All this operation takes a matter of seconds...but still it goes from 1% to 45%. After the phone is up...this percentage starts to go down even faster than before...in the end my phone shuts down again...and this time it starts to charge from 0%.
Today it shut off...and when I got home and plugged in the charger it didn't do anything...i just left it like that for about 10 minutes then tried to power it on without the charger being plugged in...and it worked. After that it started to charge. I have no ideea what is happening.
Also...my charging time is really big. I do not know why but when I use another charger from a samsung galaxy mini 2 it seems to charge way faster.
That's pretty much all so far. If you need more details, please let me know.
I hope you can help me sort this out!
Best regards!

1.Might be the battery is dead or broken, or its not calibrated. How old is the phone and battery?
2. It seems to take ages to charge my s3 lte too, give us a number in hours how much time you need?
3. The problem where phone wont turn on or show charging when battery is as low as 1%, i had this too, i think its normal, its protecting the battery
4. Do you have overcloacked anything? It happend to me when i had ovecloaced and did benchamark test, the phone froze and battery eas 5% when i restarted the phone, but before it was 45.
Not realy helpful but i am trying XD. Also might wanna buy new battery, its not that expesive

if you are running stock rom with no rooting no anything....100% it's the battery.
if not install stock and see how it goes...if it's acting normal then the mods are the problem...if it's the same it's the battery.

Do a factory data reset on stock recovery. See how that works out first

Starting from factory reset is bad idea - it should be the last step IMHO.
First what in such case we need to check is battery health.
Percentage we see on our phone is weak indicator, because it is calculated
Better to see the voltage in different situations. How to check this (terminal app or adb in console):
cat /sys/class/power_supply/battery/voltage_now
The lowest voltage that device can handle without heavy usage is less than 3500mV (I saw even 3240mV, but with low brightness, no data connection and after trying to make a call phone turned off).
The maximum voltage is obout 4300mV.
When You see 1% of battery and voltage is realy close to 3500mV or battery is charged and voltage after removing charge is dropping realy fast to then your battery very likely need to be replaced.
I bought Samsung Extended Battery (3000mAh) and this tripled the time usage than my 2 years old normal battery 2100mAh. You can see that difference in their capacity is much smaller - about 43% biger, but give me 300% much time on battery so old one was realy worn out.
BUT if your battery wasnt used for longer than half year, you can do as follows:
1. Discharge battery
2. When phone turns off - turn it on again, but into download mode (Home-VolumeDown-Power)
3. Leave phone for as long as it turns off again and repeat step 2 till time that Download Mode wont even boot.
4. Take off battery and place it back, and again try point 2 (start Download Mode) - do it until phone will show Download Mode for only 2-3 secconds
5. Again and last time replace battery and charge phone, but turned off
6. When phone will be charged, turn it on and leave it on charger for about one hour
After those steps use your phone lightly and try to repeat whole process one more time but only when the battery will normaly discharge and phone will turn off.
I tried those steps and battery for sure can work longer FOR ONE RUN, but unfortunately it can lead to loss of capacity much faster, but it will be noticable after one year - IMHO its always good time to buy new battery.

Nothing good will come from that procedure. Those steps were useful in the epoch of nickel-cadmium batteries, where the battery had no internal circuits to monitor itself and had a tendecy to uncalibrate. Those stops would force the device and the battery to re-adapt to one another.
But now we're using Li-Ion batteries, and those DO NOT like to be fully discharged. Hell, the device might not even recognize the battery, if it has really been fully discharged.

Okay...so I went to the shop from where I bought my s3 (Orange shop) And they told me to send it to their service and I did so...as I still had it under warranty. It was there for exactly a week and today I got it back. They told me they replaced the battery (which they actually did...I checked that) and the power connector from my phone. The battery it's still not good enaugh in my opinion. Immediately after I got it back...I turned it on and it had 79% battery. In about an hour it went down about 25% (so to 54%) but I didn't used it havely (note: the mobile data option was on). I really do not know what to do. I asked someone and they told me to send it again because this is not normal.
My s3 is running stock 4.3 and used to last waay longer back in the day.
What should I do? I literally got about max 5 hours of use before I sent it and I am afraid this will happen again. I do not even want to think what is going to happen if I listen to music for example.
I turned the phone off a few hours ago...then let it charge up to 59% and then stopped because I had to leave. I used it moderately for about 4 hours and 51 minutes (as my phone says) and i have about 2h and 15minutes of screen on time. My screen is using 50% of the battery and also Android system is using about 17%...chrome 12% Android OS 7% and I think everything else is less important as they use 7%<. After those almost 5 hours...while the mobile data option was on all the time I am at 14% battery.
What do you think? Is it good enaugh? Should I send it back? I really need help!
I am waiting for suggestions.
Best regards!

I think so, the fact that you have the screen on top of Android OS (and not the other way around) pleases me. You had your screen on for 2h15m, of course your battery went down fast
Test it, charge it full, and use it. Normally.
Do this for 2 or 3 days, and check how the battery lasts

Question Battery software or hardware issues?

I havent installed a custom ROM in a while so I was feeling bored and downloaded a new ROM, copied the files overs and booted to TWRP recovery and wiped everything. I cant remember what all but i think whatever was available to wipe, I wiped
I then installed ADB to my new PC and my phone was not showing up in fastboot or adb (possible driver issues) and eventually the battery died while in the recovery.
I plugged the phone into the charger and it kept showing the battery empty icon and was not charging at all. I left it on charge for hours but nothing happened.
I eventually got a new battery and while the battery still had life in it I charged it full and then went on to install a ROM from my old PC that already had adb and I used to use it previously for installing custom ROMS.
No the phone works but dies randomly at different battery percentages. Sometimes at 60% othertimes at 40% etc..
Battery drain doesnt seem too bad. When I disable wifi, bluetooth and NFC the battery only drains 50% after 24 hours but if I leave wifi on it drains faster.
When I try to play games at 100% battery after 30 minutes the battery would be at 75% and then just shutdown saying 0%.
Then I plug it into the charger and while the phone is off it'll start charging from 0% and when it reaches 25%, if I turn it on it shows 70%
Could I have deleted / wiped files that I was not suppose to that could cause this kind of a problem?

Try to make a clean ROM installation with prior the fw and formating data with yes.....
Follow installation instructions of the chosen ROM step by step and don't delete everything again except with format data yes

Did you say you installed a new battery? Was it from official service center? You can use some battery monitoring apps like Better Battery stats /GSAM etc and see what's really causing it. Otherwise fresh install, check for few days.

So you got a new battery as a replacement. If you just got this online then there's a high chance the battery is a scam and is not exactly 5020 mAh. I know this because I'm a victim of this too on my older phone, I literally have the same issue. I suggest to get a new replacement, making sure to get it from official Mi Store or service center. In the meantime, calibrate your battery by emptying to 0% (till the phone dies) then charge to 100% while off. Repeat a couple of times and the battery percentage should display correctly. There's also a suggestion of clearing batterybin stats or similar to Poco x3 Pro where you calibrate PMIC, no harm in trying because I tried it before too and it didn't seem to cause any issues.
Here's a link to the guide if you're interested:
Calibration of the PMIC (Vayu/Bhima/Surya) via fastboot.
⚠️HONESTLY READ THIS WARNING ONCE! - CALIBRATION OF THE IC, WOULD NEITHER RESULT IN A HARD BRICK/PREVENT BRICK. AS TO BE CLEAR WITH THIS *HOW TO THREAD*, IS ONLY MENT FOR PEOPLE HAVING PARTIALLY BUGGY PMIC, FACING AFOREMENTIONED ISSUES, HAVING...
forum.xda-developers.com

But the same issue happened on the original battery also

"I cant remember what all but i think whatever was available to wipe, I wiped"
So you wiped internal storage? That's probably causing issues.

Yep I think I did or at least some of it idk.. Can that be fixed?

Re-flash Stock ROM.
BTW: Always use Android USB drivers provided by phone's OEM, not those found in Android platform SDK. Then phone should get detected via USB.
