So I have been having problems with my S4 suddenly shutting down when the battery drops to 70-80 percent. I wiped /data, reflashed stock (MH8) and even flashed the .pit file but nothing has helped. Rebooting after the phone has shut itself down, I'm lucky to get to the PIN-screen before it turns off again (sudden black screen, no regular shut down sequence). The only remedy is recharging.
I noticed that my battery appears swollen, but i figured it might be NFC-circuitry or something. Would be very grateful is someone could take a look at their battery and compare with the attached image (sorry for the iphone ruler). Would be a lot nicer to try with a new battery instead of sending it away for a motherboard replacement or something. Thanks.
That definitively doesn't look normal. :s
My battery is swollen as well. Shutting down frequently especially when using 3g and browsing.
It's not normal. My old Galaxy S 4G's battery started draining really fast and shutting down whenever I had around 50-60%. The battery was swollen. You should buy another S4 battery.

I wouldn't be charging that or using it either. There's a good chance it may explode if charged or used...
Unfortunately for you batteries aren't normally covered under warranty. You might need to bite the bullet and either buy another Samsung branded battery or an OEM one off ebay.
I had the same issue, changed battery and its working again.
There's also a thread in the general section. Seems to happen sometimes...

Thanks for the help. Got a new battery today and everything seems to be back in order
Weird though, I don't usually overcharge och trickle charge my battery. My faulty one had a serial number beginning with BD, perhaps it was a bad batch.

The exact same problem has started for me too literally a few days ago. I reflashed and formatted everything because I presumed the reboots were a software issue. I only noticed today that my battery is a little swollen but not as much as on some of the pictures I've seen.
Has anyone taken the battery back to a shop? How was it handled? My phone is only 3 months old but I have it rooted so I need to know whether they will want the whole phone or just replace the battery in case I need to revert to full stock firmware.
Battery serial number also starts with BD

I tried to get a new battery from store, but they wanted whole phone, because how they said it could be the phone problem.
I ended up buying a new battery.
If it is swollen just get a new one, means that it is pretty much gone
Lol been there.. my htc battery was so swollen that the back cover would wobble. It gave me a tick to play with

Hi! I am from Pakistan and have this same battery code B600BE. It reads "Cell Made in Japan, Assembled in China". I am only posting this with an intention to help someone:
I bought my S4 (i9500) almost 4.5 months back. I am a hardcore smartphone user and do cpu intensive tasks on my phone like crazy. My battery isn't swollen at all, exactly like I got it. Sometimes, my phone heats up a lot (eg playing CoC) and I charge and play at the same time without caring about battery and cpu temp. And so far my battery life is decent. Almost exactly like when I got it new. Don't experience any reboots or shutdowns etc
So this means that not all B600BE are faulty batteries. I guess ? Will update my post if I find more information about the "faulty battery batch" manafactured (as some xda members claim).

On my battery i cannot see where the cell is made,
It just says
MADE IN CHINA / FABRIQUE EN CHINA
ENSAMBLADO EN CHINA / MONTADO NA CHINA.
Like this http://www.technobuffalo.com/wp-content/uploads/2013/04/Samsung-Galaxy-S4-Battery.jpg
But then China ipv Korea
Mine is made in China, product code B600BE, S/N: BD1D512BS/2-B. It got swollen after only 2 months. Luckily they replace swollen S4 batteries here in the Philippines and in severe cases where the battery got so swollen it broke the motherboard or screen they replace those parts too. It happens quite a lot here and the folks at Samsung Care admit it's a factory defect on a batch of batteries.
My battery is also swollen. The serial number starts with BD. It is not as much as the OP but still is. I will try to replace it using warranty.
When the battery is swollen lije that, you'd better stop using it.

Today I noticed that my battery was swollen enough to make the back cover look bulged. I got a new battery and it is now working fine. If you're curious enough about why it got swollen, maybe that was overcharging OR I was unlucky enough to get a bad quality battery.
any ways the new battery what I got is different model, It is "B600BC" and says "Cell made in korea, assembled in china" whereas the one that come in box is "B600BE" and only says "Made in china".
I'm not sure which model is latest.
Please post what model is of your battery, just remove the battery, it is written on the side that faces the phone.
My is made in Korea, asssembled in Vietnam O.O . Model is B600BE and I got it as stock with my i9505 - Poland.

I have the same problem here. Got a swollen battery but now, my back plate can hardly close perfect. I have the B600BC and my back plate was closing fine but my battery was dead so i replaced it. I didn't know about the difference un till i bought a new one which is the B600BE. You guys have an idea that maybe i have to replace my back plate?
BE version, made in Korea and assembled in Vietnam.
Haven't had that issue (yet?)
However I did have a couple of Nokia batteries do that to me in the past, I also remember reading about Apple and HP laptop batteries having the same issue a few years back.
I'm (70%) certain that this is usually caused by heat... Or storing it with too much/little power... Try to never let it get over 30°C for too long and always store battery packs with 40% charge, no more, no less, when not using for long periods of time... Swelling is the first warning of a battery that's about to explode.

I also have a B600BE came with my I9500.
It is supposed to have 2600mAh capacity and Samsung mentioned the same on it. But when I checked its capacity with some applications on playstore it shows only 2100mAh. Has any one checked it? Please reply with your battery capacities.
Application which I used to check capacity is Battery monitor widget.
Thought I should add some info...
My previous S4 was stolen a few months ago... And (a week before the release of the S5) I went and purchased another S4 at full price...
Lamenting aside.... The battery on this one is also a B600BE however it does seem to run a lot colder and last a slight bit longer...
Not sure if this is due to firmware / software changes, though I'm pretty certain I'm running more battery intensive apps than before, maybe there are differences in quality within the same versions...

It isn't uncommon for the same batch of batteries to have different performance.
Samsung acknowledged the problem of swelling with the batch of batteries with serial number starting BD. They will replace any defective battery free of charge
I don't think new S4s purchased now have any issues though

Hi,
I have a Galaxy S4 I9500 octa core version, latest official firmware available installed (MD5) and everything was fine until a week ago. The issue is like this: only when utilizing it even for few minutes only (browsing the internet, watching Youtube, sending messages, etc.) the phone dies completely and reboots. After reboot battery shows 0% (although it was almost full) and reboots again and again until it eventually dies completely. If I wait 20-30 minutes and restart the phone, everything is fine. Or if I put the charger and charge it for few minutes it comes back to life. This is a very random behavior but it happens now every day. The phone is not hot or heavily used and it happens when either connected to wifi or 3G. Sometimes, wifi settings are lost!
Before trying to master reset the phone, is any of you having similar issues (I read that there is a similar behavior for some of the users when using the camera)? Is this related to the battery?
Thanks,

You can see this strange battery graph
And this is even more obvious
usually when phone exceeds the limit SOC highest temperature, it turns off or reboot. but you say that it is not geeting hot.
so you should think about battery, try with another one.

Swollen battery
I am now few hours on the new battery and everything is fine. I am wondering why my battery swollen. Is it because I am charging the phone the whole night? A guy from the store told me that I should remove the charger when is 100% charged. Is this true??? isn't there any protection for the battery? very strange anyway. Samsung, are you aware? I am attaching a photo with both batteries, you can observe the swollen battery.

(By the way, i received many I9505 to be fixed, faulty PBA when phone is dying very quick, sometime from 100% to 0% for 5 sec, even with new battery)
Hello everybody,
I have searched a lot on this forum, but I could not find this exact problem and I am getting very frustrated. I had this phone since mid September. The phone is not rooted.
Battery life was great for the first 3 months, than something weird started to happen. I also upgraded to 4.3, because I have the gear, but I do not think this is the main issue.
When the battery is fully charged, it drains more quickly than before and from my understandin looking around Internet, this could be because of 4.3. Ok, but it is not all.
When the battery reaches 40%, it starts draining super fast, like 15% per hour without doing anything. When it reaches 20% the phone becomes really hot and if I reboot it goes into a boot loop and battery goes instantly to 0%. If i plug in the chargher, it doesn't aknowledge it and does not charge. In order to fix it, I have to remove the battery and start charging. Now I can do it with phone on or off but the phone starts to charge super fast, definitively not normal. it goes from 0 to 10% in two minutes and keeps charghing super fast till it reaches about 50%, then it starts to cool off and charges more or less at a normal speed.
Today I unplug it when it reached 50% because I wanted to look at the battery SN, as I read there are faulty batteries starting with BD and mine does too. I tried to see if it is swalled, but it is hard to say without a good one to compare. Well, when I put the battery back in and turn the phone on, the indicator showed 80%!
I am very confused, as there are many factors involved. I read that 4.3 has some issues, I read there are faulty batteries, I read that many people tried to solve with calibration, but other people say it is useless on S4...
Would you mind sharing some thoughts?
Thank you very much!
I wanted to add my batter SN is BD1D606XX. According to this post http://forum.xda-developers.com/showthread.php?t=2504093
it shuldn't be faulty...
Change the battery. Batteries are cheap. Only tc dont buy again one with serial starting for BD :highfive:

I was having the exact same issues and replacing battery solved everything. If you live near a Samsung service centre they should be able to do a swap for you with no bother. Samsung are aware of this issue and should not give you a battery with the same serial at the service centre. Obviously if you order a battery through a third-party supplier you will have to be a little more careful, but if you mention the issue at time of ordering you should be ok!
Best of luck :good::good:
Thank you. Yes, I live close to a Smsung service Center. I had already brought it in because it had stopped charghing, maybe USB ribbon. They fixed it in 1 day under warranty, so I will try to have the battery replaced under warranty. Worst case scenario, I will buy a new one, it is not expensive, but I want to find a different batch!!!

Buy batteries no from China for be safe. I was buying this one and im very happy: HERE
Hi,
My GT-I9500 is pretty new (bought around 4 months ago). For a few days I am facing problem with my battery. When battery is around 60% my phone reboots and then show 0% batter. Charging it a minute restores batter life to 60%. Here is the sequence of incidents after which I am facing my problem (don't know whether any of them is relevant).
1. I accidentally (playing games) discharged my battery to 0% for couple of times recently.
2. My problem started after I installed batter doctor to improve battery life ( don't know whether its the cause.). Not, that I had any complaint with previous battery life
3. Uninstalled battery doctor and did a full charge... problem persists
4. Reinstalling battery doctor and did a full charge... problem persists
5. Did a h/w reset.... problem persists
6. updated stock firmware through odin... problem persists
Any ideas why this is happening?
Note, that before step 6 my device was rooted so warranty is void.
Thanks in advance.

Replace ur battery for one new :highfive:
*EDIT: Your battery dont need "improve" nothing and less if was new (~4 months). The unique u did is **** it
Ok, I fu....d my battery. What I fail to understand is how?
The only control user have over a battery is charge/discharge cycle and whatever he/she does can't modify chemical composition of the battery that much to cause the symptom I am having.
This is a common and well known fault with a batch of batteries.
Mainly the batteries where the serial number starts BD. Is your battery swollen?
Take it back to where you bought it and ask for replacement.
P.S You didn't break your battery at all, it's a manufacturing defect.

No worries mate.
Just Google search "Galaxy S4 faulty battery" and you'll find lots of pages about it.
Samsung are aware and have acknowledged the issue so you shouldn't have a problem.

Hey all...
I recently had to replace my Note 4 battery and have found that the battery is not available... It's been replaced with a different part number. The old one is EB-BN910BBU while the new one has been marked EB-BN910BBE...
What's the real difference? I have been struggling with charging it fully as well... Stops right around 89%. I have factory reset to see how it goes but with the new battery it seems to drain awfully quick.
Has anyone else had any issues with finding batteries? OR does anyone know what the difference in the batteries is?
Thanks!

i have 2 original samsung note 4 battery, both are EB-BN910BBE and they have no problems giving me expected battery lifes. you can try reset the fuel gauge by entering *#0228# in dialer and then press quick start, after the phone lids up you charge the phone until 100% and leave it for sometime.. hope it works.

Yes both the new batteries I got are OEM. I have tried to charge the two new batteries to 100% but they don't want to fully charge. I've factory reset my phone and wiped the cache... still no dice. But then the question about the differences between the batteries comes up... IS there a difference between the U battery (which is the old stock battery from when I got the phone) and the E battery (which is the new replacement OEM one...)
I was personally told by Samsung that the U and E are region codes for the batteries designed for different models of the phone. They went further to tell me that getting a battery for a different region phone would have unpredictable and possibly bad results if used in a U.S. branded (U) phone.
The true differences I have no clue and have just started looking this true difference due to my battery is now failing and it is a U battery. Some things I have uncovered is the E variant is suppose to be superior to the U variant however, I keep seeing a pattern for those with 'older' U.S. Note 4s, particularly the AT&T models with poor performance from the E batteries. If it is simply bad luck or actual truth I have no clue. Still looking.
I had the issue buying 3 of the E version on ebay not knowing any difference from china. They worked fine for 6 months then completely died. noticing the original battery was U version and still working I found this link. I can confirm the phone occasionally reboot for no reason about 3 months into using them but since the phone is a couple years old I did not really suspect the batteries at the time.
1. Batteries wear out (slowly) sitting on the shelf. Buying demonstrably NEWly manufactured batteries would be in my opinion the trick to successful battery replacement. Maybe this is a problem for the obsolete Note 4. Bought a "new" battery today... Ad says OEM but is it going to be? And will it have been on a shelf for the past 4 years? Maybe. I will see.
2. Charger issue on an old phone? I do not know about this if it is an issue or not.
