Faulty battery or faulty phone hardware?

So, a couple of weeks ago I went to bed with the Note connected to the AC charger while listening to music when sleeping. I woke up the next morning, only to find an EXTREMELY overheated phone that wouldnt boot or charge. Went to a local electronincs store and it turned out that the battery was dead so I ordered a new one. (Original battery, identical to the previous)
The first day of using the new battery I ran in to some strange behavior, the screen started to flicker as if the phone was running out of battery, the only problem was that there was atleast 30% of battery left. I have been experiencing the same kind of behavior ever since. The phone suddenly drains the battery, precentages increases or decreases when not charging, or the battery is suddenly empty at 15-40%. When I left for school today my phone was 100% charged, when I came home it was probably 50%, I listened to some music, after a while it read 15%, and before the song I was listening was done the phone started to flicker (as usual) and then turned off. I connected it to my PC and charged it for about 30 minutes, and when I turned the phone on the battery read 50%?? So basically I've experienced pretty wierd battery behavior all over.
The screen flickering has occured before when using low quality charger with battery stats at ca 1%, thats quite normal i guess?
I haven't been using low quality chargers on the new battery, nor did I under the incident that killed the previous battery, however, I've been using an original Galaxy SII charger with a 0,7A output, should be totally fine right?
I'm out of ideas what to try, I've tried to delete battery stats after a 100% charge numerous times, no change. Havent seen any battery drains from the battery monitorer. Currently using MIUI Vengeance CM9, havent experience battery drain earlier with this rom.
So what do you think? Battery, phone hardware or software?

try to clean the battery contacts at the back of your phone also clean out some dusts or lints on your usb charging port. Charge it back after to 100% and see if your still getting the same problem.

The same problem still occurs, thanks tip though.

It's unlikely its hardware related, but get a replacement battery from somewhere preferably stock, they're not expensive. It's not hardware, most likely duff battery.

Finally bothered to buy a new battery (again), and so far the battery life seems to be all good!
I guess I was just a bit unlucky by having the orginal battery break, and then receiving a faulty battery after ordering a replacement A series of unfortunate and confusing coincidents

Note flickering when battery is almost dead

Hi everyone, I've experienced a problem in these last days.
Using google I found a guy who had my same problem, as it appears in this video: http://www.youtube.com/watch?v=fZQ-hbAClvE&feature=player_embedded
Never happened before I changed battery (I had the one given with the note, but last week I put another one of the two I bought, always by Samsung). One should be actually damaged because it gave me not only this problem, but several messages on screen like "battery disconnected". With the other one I started using today everything was fine until it arrived to 11% - it's not reliable though because I didn't make in time to calibrate the battery - and then it start flickering and shutted down.
Anybody know anything about this?!

I also have the same problem, I've read that should be normal, and it does not occur with some batteries. It should be due to the power supply

so there's nothing to worry about? because it happened to me 3 times and twice the Note asked me to change the time, since it was resetted to 1/1/2000... and it didn't sound normal to me :/

I saw this, too, just before my Note had major filesystem corruption. I can't think of any other reason for it. I wrote it all up over in the Q&A section.

Not adding a solution, just more info for diagnosis: My phone gets this when I'm down to 2% and using a cheapo gold battery off eBay. So maybe battery-quality is something to do with it.
As far as I know, it doesn't happen when I use the official battery.
Scared me the first few times, but it's happened five times and not damaged my Note in any way (although naturally I turn it off, give it a minute, and then start charging it back up).

well, I really hope this has nothing to do with battery quality because I bought them as ORIGINAL batteries! but they could be fake though, that's why it would be interesting to check some kind of serial to let us know if they're official or just fakes. In this case I would ask for the refund and use the old battery...
about the file system corruption, could be the battery the cause of that? because until the day I've used my original battery I haven't experienced any of these issues, so that's why I relate the battery to the problem of flickering... and that's why I don't absolutely want this junk to power my Note!

I didn't had that problem until I switched to Hydracore kernel. Now it flickers violently even under 20 % battery.

Same here.i bought my galaxy about 2 weeks ago.so its fresh. Most of the time when battry drops to 2 or 1% the screen colors going weird and finally a flashing of screen then boom going off.
Its abviously from battry voltage.
Dont forget the screen is amoled.this behavior might be from this kind of technology.
Anyway nothing wrong here so far....

Same here. I have two Hyperion batteries and the screen flickers when the battery is about to die. I've noticed it also does this on the OEM battery as well.
Didn't do this on Gingerbread just on ICS.

Its a question, so belongs in the Q&A section.​

Your Note would flicker because it's trying to get more juice out on a a battery that is almost about to ran out...
Moreover, a cheapo replacement battery or an original one that has been wrongly calibrated before would also have this kind of a symptom.

I'm sorry, you're right... thanks for moving the post, I'll be more careful!

I don't get it:
Yesterday night the phone was in airplane mode with a 60-70% charge.
This morning the phone is dead, and I needed to charge it again; after 10 minutes I switched on the device and... voilà, the battery level is 50%. WTF?!
I think I'll stay a couple of days more with this battery and then go back with my old one, asking the seller for a refund for both batteries.

Flickers on mine too.
I assumed it was normal.

Ye isnt it normal?

dead
My N7000 battery just died with the same symptoms. Damn, I hate samsung! :crying:
I can barely hear the sound of PWM charger for 5 seconds, and then just popping sound for about a minute-three! It's a dead cycle

i also experience that problem when i bought a new battery..but after few days it was gone..

suggest getting your note to service center better.

Flickering Problem Below 50% (ICS,JB)

I have contatced some Developers too but just wanted more opinions..
Here`s the problem.
Once my phone hits 50% and if i try using it after that,The screen starts to flicker..
Strange waves start appearing on the screen {Top to Bottom}
If i continue using... the waves increases and after few seconds the phone Switches Off
After around 10Minutes If i try to switch it back on...It switches on with 1% Battery...
If i put to charge it satrts from 1% if i restart once while charging it starts from 50%
So what is happening here and what is wrong with my phone..
I went back to Rooted KL3 Ginger Bread (I did not have this problem in Ginger Bread)
I flashed a safe ICS (Alliance)
It started again...
Flashed Alliance JB and it still remains,I have tried Rocket,Chrack,Crash and all Roms out there..
I did some research and got to know that sammy`s ics update had this problem,
I am open for all kinds of suggestions here :fingers-crossed::crying::angel:

Maybe your battery is dying..Try using a different one..

Battery Fault
This is a battery fault.
I had this and it went away when I changed my battery.
The only solution is to change the battery.

i had exactly the same problem!
your battery is dead. you should replace it immediately
i bought two of those:

since i replaced the the battery everything works fine.
and those anker batterys are awesome

Thanks guys and YES, I checked the battery and the shape seems to be odd...
I guess it's time to change the battery...
Thanks a lot for the responses guys..

Had the same issue 2 weeks ago. Took the battery out and tried to spin it on a flat surface. It spinned with ease and had bulged. Bought a new one from Samsung and now have no issues and battery life is great

this is an ongoing issue. seems like the battery is dead after a year with signs of bloating. this never happened to my HD2 or Xperia X10. whats going on?

Its not uncommon for batteries to drastically lose their effectiveness after a year or so -- which is why I hate phones that don't have user-replaceble batteries.

As requested by OP. Have this problem? Looks like you need a new battery.​

How often do you charge your nexus per day?

Like the title said. How often do you charge your Nexus 4 each day. Pleas take into consideration that you let your N4 run at least under 30% before charging. If you can go on without recharging your battery for more than one day please post the numbers of days.

I charge once a day. I get 12-16 hours of battery life from what I consider an average day attached are screenshots from yesterdays battery life

Once, when I go to bed - the same as I did my SGS2.

3 times, but I just got it 2 days ago. It might be that new phone usage spike. Still, I have serious doubts that it will go to less than 2 charges per day

Yep, same. I've even had 40 hours out of it once, but only because I was in meetings for 2 days and the screen was off for 8 hours at a time. that was fully charged to completely dead.

Really happy with the battery life so far, I was being conservative on my last phone with battery however now I've got this I don't really think about it so much.
Charge when I go to bed.

I got my Nexus on Tuesday night and I'm only just charging it for the first time now.
I'm only a light user though.

Once - Over night
Last's all day wifi on 8hrs - BT 1hr - texting & a few calls

Depends. When I'm at home I charge once per day, but when in at work it just sits on my desk charging. I normally use the phone more at work then I do at home, so it's hard for me to tell if I could really get through a whole day work my normal usage. I have done about 12-14 hours or so with a couple hours of screen time and still had 15% left. To me, the battery has been about 25 percent better than the gnex.

I still love my Nexus 4 and it performs well still but the battery life is now beyond dire, charging it 3 times a day.
Is it worth paying a firm to replace the battery? My thoughts are that I can just put that money towards an inevitable replacement in the near future.

I just replaced the battery in my N4. It was simple, requiring only a small torx driver and a small Phillips, plus a pry tool. The battery was cheap on Amazon and says it is an LG battery.
The old battery would no longer charge at all.

I still get 4h of SoT, and 10-12 hours battery time - so I am still quite happy with my N4. Unfortunately the camera really sucks (even more now) so I will replace the beloved N4 soon.

Yeah, I am having intermittent camera issues, a lot of photos come out black even in good light.
It's another excuse to upgrade I guess, has been a great phone though.

I think I should try the battery swap thing, mine just cannot get more than an hour and a half of SOT no matter what combination of ROM, Kernel and Android version I try, and using it during my daily commute means I arrive at my workplace at already 60% even if I'm on extremely low screen brightness. Greenify doesn't help either because it's the actual screen on what kills it, as long as the screen is off the battery drain is negligible.
Worst part is that every single battery out there is a fake, just with a very high-quality copied sticker on it. AFAIK the only way to get a new original battery is through LG and for a price you'd be better just getting a new Moto E 3rd gen for a little bit more and call it a day.

Screen flickerig on low battery despite battery replacement

Hi,
Hey i am using my note for a year now, and my phones battery got swelled, with some discussion on xda i was adviced to replace my battery which i did with another original samsungs battery. Now this new battery is charging and discharging fine, and is giving me an on screen time of 5 hours with constant messaging and music and some browsing, the issue that i am having is of battery indication and screen flickering.
First the screen flickering issue, whenever i am below 20 % my screen starts to flicker and it keeps on flickering till the phone dies, sometimes even at 15%. Then when i tried to charge it, it charges from 0.
At times when i partially charge my phone, say i am on 50% and then when i unplug my phone at 60%, it then shows 75% indication but then the flickering starts at 30% and phone dies at 26%.
The battery is giving average time so i think its not a battery issue or maybe it is.
But then i mostly found it a battery indication issue, i read multiple threads and even wiped my battery status. but the issue is the same.

may be give it a few charging cycles.. charge it from 0 to 100 with phone off.. till it says completely charged.. then check the performance..

Well yes its from samsungs outlet, dated and stamped.. otherwise the battery indicators and every other stat is good. On full charge it has 4.320 V. Discharging equally to 2.8 V. But indications is not going according to the drain and flickering at low %.

I am having a similar issue where my screen will flicker for a minute and then immediately turn off and charge from 0%. I was wondering if it could be a kernel issue as my battery is the stock battery and has never had problems before (I am on XXLSC). To me it looks like the battery is not getting enough power (hence the flickering) and then turns off. Sometimes if I turn off my phone as soon as it starts to flicker and I wait 10-15 minutes I can turn it back on no problem, other times it will just die. I have tried clearing battery stats, and was going to try my spare battery but apparently that swelled in storage.
Good luck in figuring it out! I will report back if I find anything new.

4320volt, interesting, I think its faulty, its off about 120 volts. If it depletes at a higher voltage, it looks like something is astray with the meter/level indication or battery

Sorry for the confusion it actually was 4320 mV or 4.320 v when full charged.
Let me post some screen shots. The overall on screen time is around 5 hours. So the battery is giving a good timming.
