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

Using an extended battery

Hi
Got an extended battery for my G1 a few days ago from ebay.
The problem is, the phone doesn't recognized it after I switched the battery. I had the same charging % as the previuos battery right after I changed it (even though I never charged it) and the max use time in Battery time lite is the same....
Any ideas ?
Thanks,
Nati

bad phone ? my ext batterys work fine from ebay

is there any way I can be sure ?
Maybe it a firmware thing ?

I had similar issues when I first got an extended battery (Seidio 2600mA). After performing the steps below, I had no problems at all. I hope it works for you.
Try a COMPLETE drain and recharge cycle, a couple times.
Run the battery down until the phone shuts itself off, restart the phone and let it run until it shuts itself off again. Repeat until it will NOT boot anymore. This will take a surprisingly longer time than you think. Load up your music player, youtube via 3G, etc... kill that thing.
Once the batter is so dead that it can't even load the splash screen for a boot charge it up, but do not turn it on. Let it charge up to full for a few hours (usually four will do it) and turn it on. If it's not at 100% yet, let it charge for a while longer. When it's at 100% take it off the charger and run it down again like before. Run it until it is totally dead.
After a couple cycles like this, you shouldn't have any problem with your phone and battery giving accurate charge status results and operating as it should.
I've read, from a few sources, that between the internal monitoring on the battery works, and the way the G1 reads the battery state, that this complete drain and recharge cycling helps to establish baselines for "empty" and "full" and keep them synchronized. If your phone has never seen an extended battery and the battery was at partial charge when inserted, it may not have been able to accurately gauge the minimum and maximum extents and give faulty readings based on prior battery data.
That could be wrong, and I don't know for sure. But, a complete drain and recharge never hurts anyway, and in my case it actually seemed to solve the problem for me.
Good luck!

Calibrate my battery

Which is the best style to calibrate my battery? I't only lasts for 10h.

10 hrs is pretty good
i only get 4 hours under heavy use

I forget which thread it was but it said to completely discharge until the phone switches off (ignore please plug in prompts) and completely charge it back up 5 times. It worked wonders on mine
4 hours? pah, i can kill mine in under an hour lol
seriously though, it all depends on usage and how much you have running on the phone (big widgets and social feeds for instance), screen brightness also has a big impact.
On average i get a day out of mine but my mums boyfriend, with the same phone uses it far less and has had 3 days from his on one charge

Ok i'll try your method. Thanks guys!

I have mine going down to 79% within half a day,only standby and frequent switching on of the screen, is it normal? Thanks!

So you mean discharge completely and recharge completely and repeat this 5 times?
What about the following method :
sonci said:
Just wanted to share that I got an improvement
after recalibrating the batery,
Basically just charge full with phone on
then turn off, charge, turn on, turn off, charge.
I advice this for those who have flashed the firmware..
Click to expand...
Click to collapse
So which one of these two methods is the right way to do it?
EDIT: And how good is this guide?
1. Run the device down until it turns itself off.
2. Turn it back on and wait for it to turn itself off again.
3. Remove the battery for 10 seconds.
4. Replace the battery, but leave the device off.
5. Charge the device until full and then for another hour.
6. Boot into recovery and reset battery stats (or, go to console and type “su” enter, followed by “rm /data/system/batterystats.bin”)
7. Run the device’s battery down until it turns itself off.
8. Charge to full while off.
9. Restart and use as normal.

IMHO, the battery stat is just pure witch doctor style..
Id recommend you use the phone till it drops down the 2% then power it off and charge it while its off.. that way it MAY take upto 4-5hrs charging when it says its full remove the battery for 1-2mins then install it again and charge it while unplugged its gonna charge for ~5mins and when its full disconnect the charger and power on the phone.. you just need to do this once ( on my experience ) and charge as often as possible since its not a good idea to keep draining lithium batteries

Do it this way:
Make the phone empty.
Charge it all night (8 hours + ).
While still charging, open applictaion: Terminal Emulator (it is available on the market for free)
Write:
su
rm /data/system/batterystats.bin
it looks like that nothing really happens, but it does.
Reboote the phone. Important!
You will see the difference. I get from 1 day before to 3 days now.
For doing this, your phone, of course, should be rooted.

There's another method^^
I really don't know which one of the 4 battery calibration methods that I've mentioned above I should use?

I've read from many sources to not worry about frequent discharging/charging of your battery. The lithium-ion batteries we have in our phone will degrade based on cycles (when a certain number of charge cycles have been reached). As for overcharging, the phone is smart enough to stop charging once the battery is at 100%. The battery will slowly discharge, and once it hits a certain point between 93-98% it will start charging again.
As for which method works the best...I'm struggling with the same issue. Personally I've tried almost every method other than the reset battery stat (which I plan to do as a last resort).
I have found that the battery gets better after a few weeks of use. The full discharging/charging does help marginally. The turning on and off method of charging also helps marginally. The biggest culprit is usually background apps preventing your phone from properly sleeping or activating your data when your phone is locked. I was using juice defender and my battery still drained crazy. I JUST changed my juice defender to turn on data for 2 mins every 30 mins (as opposed to 1 every 15) and it seems to have made my battery better. Before I did this, my phone drained 40% in 6-7 hours (while i was sleeping). Right now... my phone has been active for 5h48min and is at 72% (a bit of texting, a bit of 3g, and wifi). Here's hoping it'll get better.

This thread helped a lot
My phone drained 70% of battery from 5am till 12pm (while I was asleep). When I saw the battery usage stats it said that Android OS draind 68% of the battery. I flashed the phone on sunday. I should do a calibration then, right?
I'm going to try this method:

Rebooted and battery went from 45% to 10% WTF

Anyone ever heard of this? What the hell is that about?
Thanks

Happened to me all the time.
Sent from my GT-N7000

Has happened to me many times on both phones. I'm guessing battery calibration goes bad and when reboot it tries to adjust. Also note that when this happens, battery will slowly recover as if the phone is charging. Say it dropped to 10%, leave the phone aside after the reboot, battery will increase to somewhere around 20%. I've had this problem on the stock ROMs of both Note and the SGS II. Hope this helps.

Try calibrate your battery by letting it blackout then take out your battery for two minutes then put it back again, dont reboot yet, let it charge to full, then go directly to CWMR and wipe battery stat and reboot.

same here, happened to me a few times.
Does battery calib really work or its all a myth??

I don't know to consider this a bug, or what.
But.. battery calibration won't help. I've tried.
On my device, it happened :
*) when my device got very hot (when use certain kernel), I reboot, then voila.... the battery drop around 20-30%.
At first I said WTF... then I faster charge (because at that time, after drop, my battery left only 1%)
The next time happened, I was on the road, and can't charge my handphone. So I just leave it there, laid in my bag.
Surprisingly, after some times, the battery start to increase again, though it's not coming back to the same percentage as before it drop.
So is it a bug ? Perhaps... but only happened when your device got very hot.
And when your device is very hot (under certain kernel), and you never reboot / switch off first, you will see that the battery flow like water.
But when you switch off, let it cool, then boot up again, the battery will stagnant at the same percentage when you switch off. Go up and go down at the same percentage for minutes to 1 hour+.
So you want to consider this is a bug ? perhaps, but.... not everytime happen. So long as you are on the correct kernel that suit your device.
:victory:

Huge drain may affect the stats.
The percentage is calculated based on the voltage of the battery. On heavy drain the voltage may drop unpredictably (for the ROM). Also, the temperature will affect the voltage (thus percentage).
With my phone if happened only once, the night after update to LRQ so I assume this is connected to battery stats.
But also, certain ROMs can affect this behavior.

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
