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

Froyo battery % incorrect?

I let my phone run down to 16% and I was planning to let it go to 10% before plugging it in to charge.
At 16% I was on wifi and browsing websites when it just turned the screen off, made a warning sound and flashed the red battery light. After about 3 sec it started vibrating non stop which made me think of the 'discharge' feature on some phones, (which quickly uses/discharges the battery..), I didn't want it to go to 0% so I pressed (tapped not held) the power button which seemed to turn it off. I turned it back on, plugged in, and it booted up showing 0% batt.
My question is, has anyone come across this before? Should the batt % be this incorrect? and why did it vibrate..

My phone has been frequently below 15% without problems (yes, it's not very good for the battery, I know). It should vibrate once when it hits 15% and display the charge message, but that's it.
Happened once though that my battery discharged from 50% to 0 in literally 1 second, don't know what happened then, but it hasn't happened again.
Sounds like either your battery shorted or the calibration on battery % was way off on your phone. Try charging it to full and see what happens the next time you reach 16%, it might've fixed itself.

The other day my Nexus turned off at 11% :/

wipe battery stats after a full charge.. guess that will solve the problem

this isnt just a froyo issue, i am still on 2.1 and my battery dies at 8% EVERY time. it turns off, and when i turn it back on, it shows 0% but it died at 8%. its been this way the entire time i've owned the nexus. i'm not rooted so i never wiped the battery log files yet....but i will soon enough.

Ya my phone dies at 20% everytime. I just ordered a new one though

do that.
On 2.1 my N1, first my N1 had its multitouch laggy starting at 15%, then after some day of uses it shuts down at 1%.
Your battery just need to be calibrate.

[Q] drastic battery drain galaxy s

After a difficult update with Kies I was able to upgrade to Gingerbread.
Everything seemed to go well the first time then I found drain battery and slowing down on the system.
So I decided to make a simple wipe which reported the phone as fast as at first, but the battery still has problems.
In one night from 90% it was completely drained so today I decided to use 'Battery Calibration' made from user 'marosige'. This time in 5 hours I lost 30% of battery life using some sms, internet for 15 minutes, and playing cut the rope for 10 minutes. More or less.
However I have to see if the battery loses all of a sudden like last night which is the biggest problem.
All of this is not normal have you any advice?
Thanks in advance

Hi Fattox,
Dont worry your socks off I flash Roms quite often and this requires me to calibrate the battery. Sometimes with certain Roms I find the battery may drain quickly the first time and then things get better.
You say you have calibrated so that means the app you used should have deleted the old battery stats from your systems file. In saying that if you follow these next few step you should be ok (unless there are other issues causing the drain)
1. Make your you drain the battery fully until phone dies and can't be turned on by pressing the power button then....
2. Plug in phone and keep it off until battery is fully charged. Don't take it off charge as soon as it says full. Just let it go for about an hour more or so to ensure it's at capacity.
3. Turn phone on and use as normal until dead...
Providing there are no other issues causing the battery drain you should find your battery usage to be satisfactory. Remember to turn off wifi and gps when your not using them as well as maybe turning your screen brightness down. Anything that uses less power the better....
Hope this helps.

between the recalibration with the app and your point 1, I had the same problem: during the night the battery loose all the energy.. so strange.
All this after I upgraded to Gingerbread.
I'm going to test all this week then I'll spend my warranty.

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

[Q] My 1 year old Nook's battery (stats) is doing weird stuff

So I've never had a problem with my battery at all. I easily got 6h of screen on time and everything was great.
Recently my Nook started to randomly shut off at around 20-30 %. It "popped" and it was off. Didn't reboot either. Like the battery was dead.
I would have to charge it again to be able to power it on.
Also the stats seemed to be off. The lockscreen sometimes told me it's fully charged and whenever I unplugged my Nook it wasn't fully charged. The battery LED also sometimes flashes green/red during charging.
I only get around 2-3 h of SOT at the moment.
I tried reflashing a couple of times (with full wipes) but the problem occured again.
So my question is: Are my battery stats messed up? Does it just stop charging at a certain point because it thinks it's fully charged but it isn't in reality?
Any ideas (on how to fix this)?

It's almost sure that you battery is degrading very fast. But its my advice to re-calibrate your battery. Set your screen brightness to max setting and leave it on until it shuts down. Now don't power it on. Leave it charging for around 2 and half hour.
Now install geekbench benchmark app and test your battery.

If you heard a pop noise, the battery probably delaminated/micro-exploded. (Li-Ion's tend to swell and fail from the heat of (over)charging.)
There's a company, newpower99.com, who has a YouTube video on replacing the battery in the HD+. The battery sold for $25 US last year, but now that our batteries are beginning to degrade, they're out of stock.
I found another site selling replacement batteries for $80. (portatronics.com)
I've noticed that my screen-on time has dropped from 6 hous to 5.5. Maybe the Nokia N1 will be available and rooted by the time I hit 3 hours.

I'm having the same issues, and reading this reminded me of trying BatteryCalibration to reset the battery since my nook HD+ stock OS is rooted.

I had this problem several times before I installed CM. Usually, it happened when there was an update available, and when the Nook started to update, it factory reset itself.
