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
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!

I don't know if I am the only one seeing this, but when I had Eclair, I had crap battery life, to the tune of 10 hours or so. (Granted this may not be crap for Nexus One but it is crap based off past phones I have had.) I installed FRF85B last night and discovered some weird glitches.
First off, when it was in my car dock, it wasn't charging yet the battery life kept dropping, I powered off the device, and powered it back on 10 minutes later (still in the dock) and no change stayed at 91%, still wouldn't charge. I then powered it off, took it out of the dock, plugged in the car charger cable directly and powered on my N1, when it turned on, it said I had 100% battery life. I then plugged it back into the car dock, and voila it started charging.
Secondly, originally when I had unplugged my N1 this morning I used it for about an hour at 5AM and it dropped 2% I plugged it back in to top it off expecting the same crap battery life from Eclair, yet so far, my phone has been fully topped off (from the car dock) for the past 40 minutes and I've made about 20 minutes of phone calls on it, yet it still is reporting 100%. So either Froyo can't properly report battery life, or it has the potential to have absurd battery life. Anyone else experiencing anything like this?
First off - you still didn't search this forum, so you're still thinking that an overcharging protection that doesn't allow you to charge unless you drop below 91%, is a quirk. It's not.
Second, wiping battery stats and making battery calibration procedure ONCE will give you a good starting point to measure something.

The quirk isn't that it wouldn't let me charge that way, the issue was, my battery reported 91% yet when I rebooted the device with the charger directly plugged into it, it immediately showed 100%. So pretty much over the course of 30 seconds I gained 9% battery life.
I wiped my device to factory settings before upgrading to Froyo, and after as well, since my device is not rooted, my understanding is I cannot wipe my battery calibration log.
I did drain my battery fully after upgrading to froyo last night and did a full charge as well.
What you're describing looks like the statistics of the battery is "lying" a bit. I believe it can be thrown a bit off by trying to charge it when it's in 91-100% range, but I don't know the exact way it works, so I can't say much about it.
Indeed, if you're not rooted, wiping battery stats is not an option. Several times of full charge and long discharge (you don't need to go below 20%, to prevent harming the battery) are helpful in correcting the statistics.
If you get a chance to try, please repeat this again (having the phone at >90%, turning it off, plugging it into the charger and turning it back on). If it shows "Charged" again - it might be a bug worth reporting.

I'll have to try it again tomorrow morning, first see if it happens under the same circumstances and go from there. One thing I do remember is the widget I was using "Battery Left" reported that at 91% I had 4100 mAh left in it, which was interesting, and when it went back to 100% it had 4120 mAh which makes me think the OS wasn't actually reading the voltage and thought it was just draining the battery instead.
EDIT: Just realised I had my wall charger with me, battery was at 90% figured I would try, real quick to attempt to replicate the problem, I was unable to, with a direct battery connection, but it could be due to a voltage issue or be related to why plugging it in directly to the car charger resolved the issue. My gut feeling is, it has to do with the dock itself and the pins it uses.
my battery often is charging and it hits 93% and immediately jumps right to 100%. it skips the last 7% or so. i think what is happening is you just finally experienced this issue, which many of us have already posted about in battery threads, but it just happens to coincide with froyo so you are thinking its new and related. the nexus ever once in a while battery meter just gets thrown off and will jump up to 100% because it really was full, just had to catch up the meter. you really should pay attention to the voltage more than percentage, using battery life widget. i know my battery is fully charged at 4.172 volts. and sometimes it hits that but still only shows 94%, so it adjusts itself in one fell swoop.
The issue is I did an extra full charge about an hour ago so I can make it till midnight and it went through all the numbers from 89-100 with no issue

Addendum: Also it seems to be voltage is not that good of a decider of how much my charge is. Before Froyo, until I dropped below 94% I was always above 4 Volts, now I drop below 4 Volts at 96%.
So this morning I was able to replicate the problem, only it was outside of the car dock, I was able to get this problem to reoccur with the wall charger. I unplugged it from power, used it a little bit and then topped it off for the day, it was at 96%. I saw the green light go on, and thought nothing of it, 20 minutes later I went back to it and it was still at 96% and showed that the battery was fully charged.
I checked the Battery Left widget and it was saying the battery was fully charged even though it said 96% left also. I did make a crappy video uploaded to youtube from my backflip to show as well what I am talking about.
AFAIK, The green LED will light when you're anywhere above 90%. It's not a function of charge being complete. Check it.
Also, if you plugged it in with 96% - this is the behavior to be expected, since the phone won't start charging unless it has below 90% to begin with, and it'll show "Charged" - because it's not charging (to prevent overcharge).
Again, fail to see any problem in what you're describing.

Yet my phone has always been able to charge when above 90% before froyo. This behavior is new to froyo for me at least.

It means that you've never paid attention to that until now. It's working this way since the phone was out (with stock Eclair) and if I'm not mistaken - it's not controlled by OS at all.
I did pay attention to such actually because of the fact that I had been getting piss poor battery life. This has never happened before. In the morning I would use the device a little then top it off because I noticed that works give better battery life.

Well, you had a buggy phone that has now corrected itself. Welcome to the way it was supposed to work from the beginning.
Topping off the battery at 90%+ contributes to battery degradation - heating from overcharging. So you were actually damaging your battery.
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.

Hi guys
My Redmi has experiencing a bit odd behaviour every time I charge his battery
I always do full charging cycles, from 0 to 100%, and than use it till it full drains.
I usually charge it with the phone off
The last couple of times a strange thing happened: I fully charge it from 0, with the phone off, but when I turn the phone on the battery level shows something in the 70% level, the last time it was 77% only., This time I connected it back to the charger, and it went to 100%
I already installed a battery calibrator, but this keeps happening now
I use the original Xiaomi charger, or a Sony charger.
My Redmi is running the stock Marshmallow ROM - that's another funny thing, my phone simply has no updates to Noughat or ahead, I'm in Portugal those updates should have already arrived
So, any suggestion from you?
Regards
Antonio
Most probably your device has fake MIUI vendor ROM. I am guessing this because there's no update you got on your phone.
Redmi 4X has been updated already to MIUI 10 based on nougat 7.1.2.
I would recommend you to backup your all data on phone and clean flash latest stable update and restore back everything.

I'm not very worried about using latest ROM's on my phone, the charging issue is the the thing that annoys me the most, I'll think about updating my phone if and when the other problem gets a solution.
Does anybody has a say on this matter?
You should try to keep your battery level above 50%. Lithium batteries need charge to keep their effectiveness.
Only do 0-100% maybe once a month. When you do, charge the phone when off to 100%. Boot phone, if it is below 100% at startup charge more until it reaches 100%, then restart. Continue this until you get stable 100% or consistently close to it.
Battery calibration apps are trash, don't even bother with it.

Okay here is my thought on your situation.
I charge my phone upto or around 90% to 95% and recharge it when it falls down to around 20% to 25%, due to my daily routine and usage i do get around 20% battery remaining almost everyday and in very rae case it goes below 10% till now for me it never went shutdown due to battery gone full zero.
I have Redmi 1S and i charge like this and i still do get around 2.5 hours of screen on time on it which is great considering it is 4 years old device. and i am still using same original battery came in the box which now shows some ageing signs since it has little bulge on it and sometimes phone shuts downs it self and after turning on it looses 10% to 15% of its charge.
it is recommended to keep some battery % left in phone for good battery health.
over time battery does loose its capacity.
you should consider changing how you charge your phone dont let it charge fully or let it drain fully. when battery drained out completely it does takes some time to hold some charge and when you charge you phone fully the battery does goes back to 99% and goes again to 100% since it is already on charge, this keep happening until stop charging which affects battery capacity and the charge it can hold.
i think in you case this issue happening due to the how you charge your phone.

Thanks for your input
That doesn't make much sense to me since I charge it almost every time with the phone off, so once its 100% the charging process stops, and there's no way the battery should start draining because the phone is off - and even if it was on, it shouldn't loose 25% at once . If it was hardware problem, with the battery getting worn, I would never have the chance to drain it to zero slowly (it would shut down at 10% or so) or get an 100% charge level - and once I turn the phone on, he does go to 100% without any problem, so the battery seems to be ok
I do the same process with my 5 years old Sony Z1, once I charge it 100% I turn it off, and once I turn the phone on again, the battery charging level shows 100%, even If I do it a month after last charging. This old guy's battery is showing first signs of age, nowadays I get half the time I used to, but not that dramatic thing of not be able to do a phone call with 10% battery level.
So, same charger, same process, why my Xiaomi is behaving differently than he used to?
Why the charge level indicates 100% and once I turn the phone on, it shows 70 something %, and than charges without any hesitation to 100% ?

The I am not sure why is that happening suddenly using same process.
I know you've said not interested in flashing ROM just yet but maybe consider changing ROM to official Global/china stable MIUI 8 or latest MIUI 10.
Possible reason for this hardware/battery or software issue.
Maybe get device checked at official xiaomi service center or contact them on customer care support. They should help you the best.
I'm trying to do the update route, but I'm not very confident on my tech skills - and the downloads are failing all the time.
What's the best/easiest way to update my 4x?

Hi
Thanks for your reply, I ended up finding there's a MIUI tool available on playstore with ready updates for most phones, so I just downloaded the updated ROM directly to my phone and installed it.
It even kept all my apps and files, I did some backups in the process but never had to use them
Thank you all guys
have you tried
1) power off the phone and then after few seconds power on
2) charge using a different charger + different cable when your battery level drops below 50%, just to check if the phone still charges to 76-77% or if it charges to 100%.
3) if the above fails you need try factory reset or flash latest MIUI rom
