screen flickering - a common problem?

Hey guys!
Recently I read a lot about people who are facing the screen flickering issues on their Note. (YouTubv-Video, thanks to Parth)
For those who don't know about the problem:
When your phone is discharging it'll randomly begins flickering and shut down, then restart with 1 % battery left. The performance of the battery is dropping from around 4000 mV to 2500 mV... A new battery should fix this.
The strange thing I've noticed is that those people bought their Note around 12 months ago.
I bought it in November 2011 and got the issues around 3 weeks ago.
Could this be a common problem? Let me hear your opinion / experiences.

I've had this flickering for the first time about 1 week ago, after I replaced the original battery with a fresh one (from Anker): The flickering began when the new battery had 0% left. But instead of shutting down, the phone was flickering for about 1-2 minutes before the battery ran out of power and the phone was instantly switched off - without a "clean" shutdown. So it seems that the new battery does not "tell" the phone to shutdown before it is empty, and the flickering might be a symptom of a very weak battery. Just a guess...

Yes .. it happens on low battery. have noticed this on 3 notes already

Think you're missing the point of this post...
To op, bought mine same time as you and flickering began 2 weeks ago, plus now needing 2 charges a day on original battery. Have just ordered a replacement. But yes, the timing is uncanny.

geez ..i thought it was just me ... I also notice this just about 2 - 3 weeks ago ... Strange thing is when i recharge it and check the battery starts ...
there will be a drop from 30% --> 0 % and charging starts from 20% upwards ...
I still have the original battery from Samsung ....
Also noticed that the battery is getting hot every time I have the screen on for more than 4 mins ...
I purchased my Note in October 2011

My battery became worse more and more... Recently I got a drop from 98 % to 1 % Already ordered a new one, hope it'll arrive within 7 days

You should see for media scanner issues and wake locks using betterbatterystats

my note is 15 months old. i started having this flickering issue 2 weeks back and got a new samsung oem battery 5 days back. the new battery has manufacturing date of 2012.12.27 on it. the flickering issue was 98% cured after getting a new battery as the only time i got flickering issue with the new battery was when my battery level was 8%.
now the strange thing happened yesterday. i was online on facebook for quite a long time on my note, upto the point when my battery reached 1%. then i decided to give it a rest and turned it off manually via proper power off. my note was turned off for about 2 hrs, then i came home and connected my charger while my note was turned off, but the charging indicator never showed up. i thought maybe it will take few moments for it to show up. i checked my note again after half an hour but it still wasn't showing charging indicator. i tried turning it on but it didn't turn on. i tried putting my old original battery and it worked perfectly as before along with the flickering issue. it was charging as usual so the charger is not the problem. i tried putting the new battery again and still it is neither turning on or showing charging. what am i supposed to do now?
EDIT: i think my new battery has gone into deep discharge. is there any way to revive it?

same issue
Guys i dont think this is a simple battery issue.... I think this may be a media bug on rom Jelly Bean ...
I have the same problem and the batery was full charged with 98% ... I just unplugued for the charger and it just flickered screen and bummm phone off and battery drain... and it allways heats up the phone.... I play a game a lot called rage of bahamut and it started all by playng that game lot of time...
Now the problem is gueting worse... just by watching a simple site it goes down .... this is NOT a battery issue...it must be from the rom or kernel ...
its like something its not controling the battery usage correctly ... it only hapens when its not plugued to the charger....
can some op say something about this issue?? Please

First thing first....battery calibration THROUGH wiping battery Stats is one of the BIGGEST LIE on Android.
I remember someone Expert on android posted that on Google+.

Ive tried many things to solve it..
+Screen flickers afrer reboot right?
+(Maybe) phone shuts off after capturing picture with flash right?
+Battery spins right?
+Playing intensive games makes phone shut down(sometimes) right?
+battery percentage not accurate right?
Im not arguing brother.. :thumbup:

All im saying is that I experienced all you said and solved my problem by changing battery..

I have had this problem on some ROMs only. When I switch back to a known safe ROM this problem goes away. I'm currently on Asylum 23rd and do not have this problem.

Problem solved...
It was battery...
New battery runs smooth... No more flickering or shut downs...

Battery Instability

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?

May be time to get a new battery

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.
This turned from question to possible Samsung defect. So, I am agree originally I made wrong choice. But, this topic is suitable for here in the light of my new finding.

I have the exact same problem! Been wanting to change the battery but haven't found it. If you buy a new battery and everything comes back to normal, please let us know!

I have same issue as OP. My screen starts to flicker at 15% as if it's about to lose power any second.
Happens with OEM battery as well as two aftermarket hyperion batteries.

Same here.. my batterry was a little bulged at the middle and i thought it is still ok.. then it started acting up..
-It says fully charged on the battery indicator while turned off and charging
- when I turn it on, it says 50%..
- when I get to recovery (philZ stock kernel recovery) it says 1%
Then it got worse and wont turn on when unplugged... Bought a battery at our local samsung store and all the problems went away!

Awesome!! That's what I wanted to know! Now I'll look for the battery.
Does anybody know why this happens?

I had this issue last month. Changed to Mugen battery. Everything's good now.
All the symptoms described here are dying battery issues. Have them replaced before your note dies.

I was unaware of this situation and I downgraded by JellBean to first GB, then ICS. I am lucky it did not shutdown during firmware install.
I went to some official Samsung technical service. They will give me a new battery soon. I am using my Sony Ericsson Walkman series phone Luckily I have iPad with cellular. Now, I will just wait and I will hope everything will be ok.

I bought a 7000 mAh battery on ebay. It's awesome! No problem now. My battery last all day :good:

[Q] Extra battery

Hello everyone!
So I bought this battery about 3 weeks ago http://www.ebay.com/itm/221203252844?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 , and expected it to be better than stock, but it unfortunatelly isn't, so here's the tip if anyone is thinking about buying an extra battery, this one is about 20% less than stock.
Has anyone else bought extra batteries for our 4x hd? What's your experiencie?

I bought 2 onite batteries at 2350mah apiece. They seem to last a lot longer than stock.

Anyone else ?

Hello , I bought new ones from ebay couple of weeks ago , a pack of 3 batteries. so far I tried one of them , first day I turned off my phone and put the new battery in and plugged the charger in without turning it on , it showed that the battery is 3/4 full. Then i kept it for 8 hours, but i kept checking it every now and then , the battery was decreasing ! I thought that theres a problem with the charging animation ... After 8 hours i turned the phone on , it was 3%. So i left it charging while it was on , surprisingly it started charging , up to 83% , then while plugged, it started discharging ... The day after it was charging till 90% and it stayed 90%. I dont know whats the problem , it may be from the charger , i tried different cords but I didnt tried different adapters because that was the only lg original charger, i dont want to try chinese ones ..

Well that sure is weird, but why don't you try another battery? Didn't you buy 3?

I did , but I am waiting for the current one to see if it might work well , you know like give it 1 week , maybe in full charge/discharge circulation it might work. But I'll be testing the second one soon , I think ill come back to post my results.

I have very good experience with Polar Cell batteries. They are a bit pricey, but they are built in Germany and have a real capacity. I haven't bought one for my 4x yet, but if I buy a spare battery, it's going to be one of these.

Does a damaged battery affect performance?

Hello
I wanna ask if a damaged battery can affect performance of my S3 Mini and what's the average time the phone is able to stay charged with a completely new battery. My battery time sucks (i get max 9 hours if I don't do almost anything on my SMARTphone ). So will replacing my battery solve some of the lag on my device and how many hours should I expect from the newly purchased battery with average usage (max 2 hours music, a few phone calls, max 1 hour gaming-small games mainly and sometimes web surfing). Thanks to anyone that replies. Cheers
EDIT : My battery also heats up to 36-39 degrees celsius while just playing Soccer Stars while listening to music from PowerAmp. I think this isn't even close to normal. If a new battery solves all these issues, I'm willing to buy the best one (presumably original by Samsung)!
EDIT 2 : My phone charges from 1% to 50% for about 30 mins

Maybe you have a super charger joke make sure that your battery isn't swollen. And yes a battery can affect to performance and hardware. If you use very long a damaged battery then it also cause hardware problem. One time this happen to me on my old LG phone. The battery always got more swollen, so i bought a new battery but only 1 month later was the new battery also swollen like the original battery. It was a hardware problem and i still have this phone with a swollen battery

you should use pure stock rom beacuse most of the custom roms have some battery and voltage tweaks which can cause hardware problem if problem persists then replace your battery

Thanks for your help guys. Recently I tried pure stock ROM, but it was the same, plus I kinda love custom ROMs, which have more battery time What would you suggest I buy as a new battery - an original one specifically for my GT-I8190 or the Ace II battery (which is cheaper) is of the same quality as an original S3 Mini battery ? My current one is for the Ace II (it's the second battery I've changed on this phone)!

if the s3 mini battery is not much more then go with that & see if there is much difference

Dead battery!!!

Hey, got a weird issue with my device.
Just 4 years old piece and already this has a dead battery!!! Cannot use it anymore basically... drains overnight on airplane mode from 75-80% to 0 in 7 hours!!! Last night I left it fully charged and shut down just to not starting anymore this morning because there is no power left, battery is EMPTY!!! Just barely started to charge!!! Something is wrong with this phone, really wrong!!!
I tried custom roms but the phone has the same behavior... so I came back to MIUI 12.5 just to be in the same position and to have the same conclusion: I HAVE A DEAD BATTERY!!!
I went back to my old Redmi Note 5 Pro with a custom rom... just like knew. How is this even possible??? An older device, with same amount of use have a better battery life than a newer device??? Different battery manufacturer, some production flaw in the battery production? Either way, conclusion is clear: NEW BATTERY... so, so disappointed by this situation...

Batteries get old and die , you have to change it , or maybe there is a short circuit on the motherboard , best option is to take it to a repair shop

I know.
But I found out that in fact my phone is only 2 years and 3 months old??? So, is this battery old enough to die? I guess there is something else here.
In the meantime, I already change the battery, sadly not with an original one... and so far so good, but only a few days passed. This battery however is acting strange! Does not charge more than 86%. Aida64 reports battery full at this precent... but I guess time will tell if I made a bad/ good choice.

encounter the same problem after 4 years of using redmi note 8 battery drains so fast unlike before and changing the battery to a new one it either does not fully charges it to 100 percent and it shutdown when my battery percent is around 20 or so percent but when I try to connect a charge and remove it, it will open up to that 20% or so percentage and continue to be used, I'm guessing the it need a battery calibration but I know really know what to follow on the internet.
