Battery Instability - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Nowadays I have a weird problem. Even though I fully charge my phone, it behaves like battery is empty. It happens in two way:
1. After some usage, it can occur at 15%.
2. While showing battery is charged enough, you restart the phone. It starts as ciritical battery level.
3. For case 1, it can happen at higher levels as well. Screen starts flickering then phone shutsdown suddenly.
I tried calibration apk. I suspect it caused some problem also.
My system was stock 4.1.2 leak. I thought it may be reason, so I downgraded to ICS. But, I still have same problem...
Any1 has an idea? Battery or phone has problem or not?
Edit:
I opened back cover now. I am very surprised. Battery got deformed. Middle part became thicker. It cannot fit to battery slot.
I think god saved me. It could explode.

Yeah same post in general too. And answer us battery issue

[SOLVED] Incorrect Battery Values

This seems to be quite a common and somewhat obscure at the same time.
Many people have reported installing a new rom or even just powering up their phone and seeing a battery % much different from what they expect. Most often much lower than it should be. Evidently this corrects itself after some time but it's a real problem if your display reads <15% because you really have to plug it in then, even with you know you have 90% battery!
So, here's the solution after testing it under different circumstances over a few days:
Simply boot your phone when it is not plugged in to a power source and battery % will be accurate.​
That simple. Silly LG!
So, if you flash a new rom, unplug the USB cable before you reboot...
Hit 'Thanks' below for the 50 reboots I did to prove this...
hehehe jups allready figured that out on myself tho haha. But indeed that's kinda silly of LG

What about every time I use a custom rom the battery % indicator jumps right down to 90-95% when unplugging from charger ? Do you have a solution for that ?

Try rebooting after you disconnect power.

Sorry to say the same..
Even while charging with the phone shut down, pulling it off the charger and then booting this happens. On my phone I have experienced it on all MCR's.
It's really not a big deal as long as the battery performs as Stock 10b, that build has been stable batterywise on my phone. But staying stock isn't too much fun
Well, every time I charge, whether I reboot/shut down before unplugging or not, my charge always maxes out at 96%.
Annoying and I'd like it sorted if at all possible.
Anyone?..........lol

ye i got that exact same issue i was wondering why that was happening and hoped that a simple reboot would fix it but its a bit more complicated than that i suppose...
also the battery reset in cwm didnt fix the loading till 97% w/e percentage.
when i install the stock rom it allows me to load it till 100% though pretty weird stuff -.-

I had a replacement netbook battery that could only max to 90%. So, over the weekend, I practically drained it to 0% (not a healthy practice for Li-ion batteries but I was desperate). Took out the battery for a while, and then recharged for several hours. Well, it seems to get up to 100% now.
Perhaps you could try using the the phone until it very low on battery before recharging. Maybe the charging process in the phone needs some sort of recalibration. But should not be doing this all the time as it will reduce Li-ion battery longevity.
Let mine totally die last night so it wouldn't even turn on at all. Took out and replaced battery and then charged it overnight and hey-presto, when I unplugged it this morning, it stayed at 100%.
Solved indeed....for me anyway. Feel free to try the same and post your results.

I'll be sure to try your tip man. But not easy drain it completely when I always need the phone :=)
I guys! I've got the same problem.
I think that it could depend on the "full battery popup FIX" that Paul introduced in his roms by the FR8.
So I would like to ask Paul if you can create a patch to remove that fix. Just to try it!
According to me, incorrect battery amount depend on a wrong voltage read error (offset introduced?) by the rom. :blink:
In my case, I have followed many times battery wype procedure without positive issue. The matter leaves only by flashing original roms.
I think that if Paul have written a wrong battery values range (to delete the battery full popup) that can be traduced in an incorrect battery status displays.

It was occurring before Paul introduced that change unfortunately...
After I wrote here, I registered a premium account to Paul's from modaco site and toke a custom fr12 rom without "battery full popup remove patch". Now I'm going to sleep and plugin the 2x to charge. Tomorrow I'll write here if is that the solution...

I'm sure it's occured from fr8 in my case. With stock rom I haven't any battery problem so there is something wrong in fr raleases of course... I hope somebody discovers what is...

Perhaps, but you can not conclude it was introduced by MCR. You logic is wrong there.
Even without "battery full popup fix" it doesn't work good...
Battery level, when unpluged, stay at 100% for 2 minutes afterwards drop down fast until 85% then drain normally...
I'm getting huge battery display problems no matter what I do.
When I took it off the charger this morning, it said I had 100%... thats fair enough. However it stayed at 100% all day, so to "refresh" it this evening I restarted the phone, and low and behold it now says I have 27% left. But again, it's just sticking at that value, even with me now plugging the phone into the wall to charge. It simply says "Charging (27%)" and won't budge, likely until I restart the phone again.
Sometimes it works fine, it seemed to be doing ok last night before I put it on the charger. Any tips/suggestions? Is this something likely to be fixed when the Gingerbread update rolls around?
This is my first real smartphone, and am fairly annoyed as its giving me a fair few problems that I've not had from other electronic devices.
As I stated in another thread, I had the same issue while on MoDaCo Fr12. However, after reverting back to stock, the battery percentage is spot-on and I'm getting up to 48 hours use out of it.
Draw your own conclusions.

That sounds super, but I'm still on stock too. About the only things of note I've done are root and switching to Launcher Pro. Oh, and Clockwork Mod of course. Perhaps a complete reboot is needed, we'll see how it goes.
Saying that - since charging, my phone has been at 90% all evening, until right this moment when it changed to 89%. It's less than I'd expect on this type of phone for 3-4 hours use (or lack thereof, I've barely touched it), but it's a start eh?
Welcome to the world of smartphones my friend. I've had various handsets over the last 4 years from iphone to android and a day and a half out of the battery is about average......at best. ;-)

Just to clarify, what I meant in my previous post was that I was expecting to battery to drop a lot more than it did. The fact that it only went down 1% in several hours of use prompted me to think that the battery value was messed up.
As it is, I've not charged my phone in the 36 hours since, and it tells me I have 73% battery left. Perhaps it is performing extremely well after all? If that's the case then I'm more than happy with it, but being the pessimist I'm still expecting the phone to turn off sometime with the battery reporting incorrect values.

[Q] Galaxy S Plus battery swelling?

Dear fellow enthusiasts,
since a couple of days, I'm experiencing sudden device crashes when I'm using it for network related activities, mostly over the 3G network (for example, I'm typing out a message on the Facebook app, and the phone goes into boot loop or simply "shuts down"). I had only recently upgraded to the 4th beta build for the Cyanogenmod 9, hosted here on XDA , so I suspected it would be related to this. However, upon reinstalling both the previous version and the new mod from absolute scratch, the issues remained the same.
I had noticed that after each crash, the battery charge displayed as very low (2-6%), whereas I'm certain the charge should be much higher. So I thought it might be some sort of corrupt battery-cache issue or something.
However, and here's my actual question, I just now noticed that my I9001 battery is slightly bulged, on both ends. This bulge starts just above the white printed SAMSUNG lettering, and it ends just bellow the QR code. I can't for the life of me remember if or not this is normal, so could someone please confirm this for me?
And while we're at it, could a faulty battery affect my performance as such (making my phone crash etc)?
Thank you very much in advance for any help or information anyone could give me.
I confirm, battery is slightly bulged in those places but it looks like a production "thing" to me (I hope I understood what you mean), no need to worry, I guess. Looks like corrupted battery stats, try to wipe it via recovery (phone fully charged, plugged in - then wipe battery stats). After that, i recommend one or two full battery discharge - charge cycles. I've noticed hovever, that after each full factory reset I have for about 20% better battery drain, than after flashing many ROMs, kernels and updates (cache and dalvik cache wipe only), my battery drain is getting pretty annoying. Try a full factory reset, if wiping battery stats didn't work.

Hey people,
I received my new battery last night, I went for an Akku Powercell of 1800mAh. Charged overnight, been using it all day, no problems whatsoever to be found.
Thanks again for the assistance!
Swollen battery = defective!
I'm sorry but I've encountered this as well in the past. Normally working phone with sudden shut downs and huge drops in battery charge. It took me a long time to convince me that the battery was defective. So maybe this would save you guys some time in finding this out!

In general healthy batteries DO NOT swell. Buy a new one before it explodes or starts leaking...
Hey all, just because people keep on posting, the battery was indeed defective, the roms were absolutely fine and the new battery is performing marvellously!
Thanks again for all the input !

I have the exact same problem with my sgs i9000-gt.
My phone turn off itself ( no restarts, its a complete shutdown ).
First, I thought i might be a problem of GB 2.3.6 rom i was using, so i updated to latest cm10 but the problem persists.
If you restart the phone after the shutdown than i shuts down within a minute again.
Also the battery drain is pretty fast. I notice the same bulges on the battery as reported in this post.
I did the battery calibration thing as some people suggested, but that does not solves the problem. However, it got rid of the fast changes in battery status which was happening before. Like when you restart after shutdown at 80% battery status, it will show like 2% battery left and after few minutes of charging it would boost back to 80-90%.
But still the battery drain is pretty fast. It discharges from 98% (i cannot get to 100% charge, 98% is highest) to 50 % within an hour, just idling.
And when i am around 40% or so and if i recieve some message and try to open a app it shuts down again.
I have ordered a new battery just in case. Will update here if that improves things for me. But i will still like advice on which is a more economical kernel and rom for i9000-gt? Some people suggested slim bean + semaphore on some forums but i would like to have some more concrete advice before i change more things without knowing the source of the problem. I would be grateful if someone can suggest what is best to use with some details( version, etc). Thanks for that in advance.
I thank you all (users + developers) for all the useful information provided on this forum, i learnt a lot although i still am not able to fix my problem . And I hope someone might come up with a concrete solution for this problem. If there is a solution which I might have missed, I thank you in advance again and hope you will be kind enough to point me in the right direction.
cheers
update: the phone stays alright if u dont do anything on it, but the moment you being doing something on it other than playing with system settings, like run some app, especially something that uses network / wifi, it shuts down. none of this happens though while its plugged in. it happens only when its on battery.
problems fixed so far after replacing the battery

I flashed back to stock samsung rom ( from the value pack) and the problem persisted.
today my new battery arrived and all the forementioned problem seems to be gone with the new battery, my phone seems to be working fine for last 5 hrs without any restarts or crazy battery drain. will test the same with custom roms again. As of now it only seems that problem was the battery.

[Solution] Flickering screen, poor battery backup, sudden discharge [n7000, Note]

A month or so back I started facing weird problems with my year old Galaxy Note, n7000:
1. After reboot, the battery would go down by 15-20% and then without charging the battery %age would gradually increase by 5-10%
2. lots of flickering on screen followed by auto shutdown whenever the battery %age went below 15-20% after normal usage
3. Very poor battery backup (I blamed most of this to the Rom Mods I had been installing at that time- only partially correct!)
I am sure that many of you might have been facing such problems and running from forum to forum to get a solution- I did.
Solution:
Get your battery replaced- most of us have had our Note for a year and some months now...life of the battery is approx 1 year for regular use, thus, the stock battery that we got with our Note is well past....
I never faced the above problems after battery replacement!
Hope this helps others like me!!
I started having this problem after getting a new battery, my old battery which was weak never showed flickering. But this new one which is original samsungs battery at below 15% show flickering and sudden discharge despite a good battery time.

I got rid of the damn problem after getting new ones...Is it possible that the batteries you bought are not genuine/fake?
Which ROM are you on- the Stock one or some mod-rom?
When I was searching for a solution to my battery issues some members suggested battery-calibration and full charge-full discharge cycle to get rid of the problem. Both the solutions suggested at that time did not work for me.
There was also a solution about cleaning the mini-USB connector which gets seriously dirty collecting grime from our pant pockets! That did work for me initially when the battery was good.
Please let me know if any of the above helps you.

Guys - Me too have the same issue, but this started immediate after updating the Jelly Bean 4.1.2. It never happened while on official ICS.
I could observe the battery is very much thick now, which is a symptom of over charging. The screen flickers and brings phone down abnormally.
After connecting the charger for a 5 seconds, suddenly the battery level shoots to original state from where it went down. Most frustrating, it happens very frequently.
I am not sure if the same will persist even after replacing with a new battery. Or I would need to go back to ICS again.
Any suggestions?
Cheers!
If the battery is bloated then it's better to get a new one.
Erm... is this thread still up?
I just wanted to know if the bloated battery would cause boot issues, stuck on the model screen?
I would guess the problem is with the bloated battery's voltage is insufficient to power up the systems... i guess
I need confirmations... thank you in advance

4.1.2 xxlsz deodexed by eybee
The problem is, after I restored most of my data, apps and system data separately, the screen flickers a little bit and then the restore process completed without any problem. After that I restart the phone, stuck at the model screen only for unknown reason. The data is also from previous xxlsz which I had trouble with some system app crashed but fixed by returning to another backup though.
So, currently I'm leaving the phone without any data restored, only stock fresh out of the box xxlsz with titanium backup only installed. So far the phone is quite stable, I've turned off the adaptive power adjustment in display as well as lowest brightness just in cast it might occur again.
I've been reflashing xxlsz a lot this morning, over 3-5 times due to stuck in boot logo and model screen. Even though flashed the latest philz 4.90.8, it would just revert back to the old philz 4.8x with cwm 6.0.2.8
One last thing, my batter bloated pretty bad about half of it has been expanded. I mean from the bottom part (no copper connections), half of it has reached out of the body.
Well,
hppend to me b4, flickering issue below 10%. It was bloated. Bought new one. Bloated again after 6months. Again, bought a new one and it can last only 7 hrs without switch on data.
This is what we get from massive production company.

I seem to have the same issue
1. Battery drains rather bad
2. Screen flickering
3. Auto shutdowm
Used the battery in my wifes n7000 , however no issues at all
Only seem to happen on my phone.
I flashed it to stock std 4.1.2 , however problem still persist. auto shutdown few times a day
Gets worse when i use an external SD
@amogh you can check your battery voltages and battery temperature and compare that to optimum values. you can also use apps like AnTuTu battery tester.

Flashing another rom again wont solve much of the problem, if you happens to have the phone stuck in around bootloop and able to go into cwm, brace yourself, this process can get very repetitive to solve because a mere battery able to do such a problem. I had these experience before about 2 months ago before buying a new battery. Hope this link helps you understand a bit more of the battery

Why does this happen?! Battery annoyance.

Just when I think I've got it all setup nicely...
Latest AOSIP rom with Hellscore kernel, stock settings greenify, full discharge and recharge, all seemed so good....
And then boom. Go to reboot to recovery and I get the little empty battery icon upon reboot - but I was at around 40%?!
I use the battery calibration app, for what it's worth knowing the debate about the battery stats file. I've done the bootloader logs 'trick' and still I get a random occurrence like this?!
Anyone else been plagued with this randomly happening to them?
There are so many reasons it can happen. on thing id recommend is install ampere form play. Using this you should be able to monitor the voltage of the battery and at least know that it is operating within the correct range. if your 0% voltage is too high, it could rule some stuff out.

Cool. Just periodically check the app and jot down the percentage and voltage. keep doing that until its ready to shut down. preferably a reading every 10-15% if you can but really important is to try and capture readings just before and after any drop off you may see.

Perfect thanks for the advice, I've got it installed and now juts doing a full charge.
Following that drop out, the device then reported 7% battery so I let that go flat and now fully recharging.
If it's the case that there is something going on here, how can the issue be corrected? Does Ampere help configure reported VS actual readings, or does it purely show what's being drained?

Its worth getting a voltage reading now too then, to see if it is as low as expected. As for solution, we need a root cause first.

Ok here is my first screen. I'd browsed Facebook (web version) and watched a video or 2, battery dropped to 97% soon after.
Yep. Just keep going. Every 10% is fine. No more than that. Actual battery charge is voltage so we just want to see if there are any conflicting data sets later on

It just did it again!!?
I had even doing the Ampere monitoring but didn't go all the way down. But today I just experienced the random drop out again. Strangely when I booted back up, it was as if the cache had been wiped as the Android Optimising app screen came on.
This was from the other day though, if this helps?
The other day did it seem to deplete normally? I'm around 20%/right now and see similar voltage to you.
Sometimes my phone used to crash and when it booted up I had this graph / drainage issue. It's as if it goes into some manic sleep that kills everything. What you've got here seems similar. I don't think there's an issue with the battery cycle itself.
I'd be tempted to do a factory reset and start clean to be honest.
Is the back of your N6 lifting away from the frame? I had this issue too and ended up doing a RMA because the battery was bulging.

Weird and annoying isn't it!
I've recently flashed this new rom and so has been a fresh start so I'm kind of at a loss as to what to try next.

Just took off my case and checked and all seems normal, back doesn't appear to be coming away and seems to be ok.
It's times like this I miss my good old Note 3, never had a battery life like it for its flat lining ability!! (see attached)
If it were the battery capacity due to bloating, I would expect to see the Voltage value to be wrong
Go back to stock and run it with no restored apps / data. If it still happens RMA

Just when I think I've got it all setup nicely...
Latest AOSIP rom with Hellscore kernel, stock settings greenify, full discharge and recharge, all seemed so good....
And then boom. Go to reboot to recovery and I get the little empty battery icon upon reboot - but I was at around 40%?!

Your battery calibration is messed up. It happens.
DO NOT waste your time with "battery calibration app" -- there is NO software you can install and run from Android that will have ANY impact AT ALL on the battery calibration. All those "battery calibration" programs do, is delete the battery stats file, and all the battery stats file does, is store a log of what programs are responsible for how much resource utilization -- nothing at all to do with calibration.
Battery calibration reset is done through the BOOTLOADER.
Reboot your phone to bootloader. Scroll to "bootloader logs". Press and hold power button until the phone shuts down.
And that is all there is to it.

Thanks for the reply.
Unfortunately, I have tried this many times and so there must be more to it than this. On my latest rom, I had wiped phone and clean flashed whilst phone was connected and at 100%. Therefore a new clean install whilst phone was at 100%. I cleaned that stats (for what it was worth) and also did the bootloader logs trick. I would have thought that would have solved the issue, but as reported it still happened.

Your calibration is fine because the % matches up to the voltage, which is all calibration matches.

Thanks yeah, I thought as much.
The question remains then..... What in earth causes these drop outs!

It's hard to say. It seems like the system may be crashing or something at that time and causing an inordinate drain. Thats what mine used to do sometimes.

Battery issue and restoring completely to stock

Hello everyone,
I have been using a Xperia Z1 for around last 6 months and updated to Lollipop 5.1.1 two months ago. Everything was fine until last week when my phone started to get affected by the battery bug.
The phone works fine and the battery gets discharged in leaps. For example, when I use the phone from 100%, it goes down in the usual way, let's say for 1 hour usage it drops up to 90% which is quite normal. But, when lock the screen and keep it idle for sometime and when I take it back, the battery has dropped a leap, usually by 10-15%.
Yesterday, I was using the phone normally and kept it idle for the entire night and battery has been dropped only from 85% to 79% without stamina mode. That's good. However, when I restarted the phone in the morning, the battery suddenly dropped to 18%. :crying:
I tried calibrating the battery, charging/discharging cycles and removing batterystats.bin. But, the issue is still here.
I think my phone has been affected by the famous Xperia battery bug in Lollipop which means that my battery is damaged. But, before replacing the battery is there anything else that I could do to overcome the issue. Any suggestions are greatly appreciated.
+ My phone is rooted on stock 5.1.1 (14.6.A.0.368) with XZDualRecovery and locked bootloader. If I repair the phone with PCC will it cause any harm or bricking since because of the customer recovery?
Claiming warranty is out of option since the phone has been rooted and flashed with custom recovery.
I don't know why people call it a lollipop bug. There will be a time a battery reaches its end of live. That's what has hit you right now. Your descripte symptoms are from a dying battery. I have seen some dying battery's from me or friends. The battery was holding the charge normally and suddenly no more.
Replace it and all should be fine again.

But, can this happen on a phone that is just 7 months old? Thats what makes me to think that this could be a bug.
I have the same issue, but mine drops to 0% and after waiting some time and booting it the percentage is back up. I have my phone for 2 years now, and the problem appeared in Lollipop also.

It's okay for a 2 year old phone as Lithium batteries wear out with time. In my case, it's kinda disappointing...
So, after searching the entire Internet, I can understand that this is a common issue with Xperia Z1 and Z1 compact and replacing the battery seems to be the only possible solution. I searched EBay for a battery but couldn't choose a good quality one. Can someone guide me on this please?

Your battery is definitely dying and it has nothing to do with roms. Get a battery that the seller claims to be OEM. That's your best bet...

Thanks for the tip. So, I searched for an OEM battery and ordered it along with some tools required for the disassembling. I will keep posted once I replace the battery.

Don't think that it will resolve your problem.
I changed my internal battery about one month ago and when two weeks passed I started to experiment the same bug ? again
It's not only hardware problem, it also software problem, I believe.

You are correct becouse I experience som drops in the range of 5-20% in less than a minute and once 30%. All the time while the phone was in standby mode except once where it did it right in my face (10%). My battery status is reported being fine. I also forced shutdown the phone as per the calibration method for non-rooted phones. Though I did notice dalvik cache wasn't rebuilt and so there is no way to have it refreshed manually except system updates which does this.
Anyway I did remove some apps and did some changes and after this I have not had any sudden drop for weeks. Two of the apps where Truecaller and Facebook official app. Will check though if it was a third one to. I believe one of these or both where playing havok. Especially the Facebook app as it takes liberties I find suspicious, is buggy, can crash the kernel (any app that can do that is doing shady work IMO) and had the addition of a "Video Player" service that was running permanently after you launch the FB app once. I instead use Metal for Facebook now. Pretty much same experience, only 10MB RAM used instead of 90MB and no batter y drain either or any other problem. So in short I believe one of these where the culprits and since many use the FB app that might be the one playing badly with Sony Z1 system.
And If you use Adguard also check if there are apps getting high ratio of ads blocked (or analytics data blocked). Might be some dont get proccessed right in the battery system due to it calculating it wrong. Google Frameworks, Google Contacts, Play Services, Mobilestorage Checker and a few more I disabled the ad filtering for. Though this did not change the battery drop problem previously. It only went away when I uninstalled named apps above.
