My Galaxy Note battery is slightly fatter after charging

Hi everyone,
I just charged my phone and the battery seems to be fatter after it was charged. I'm a little worried if this might explode or something. I opened it up and looked and the battery is cool and nothing is leaking from it but the battery looks slightly fat. This has never happened before since I got my Note. Is this normal?
I charged it using my laptops USB port when this happened. Also most of the time I charge it from the wall.
I get worried because batteries can be the main cause of device failure so I don't want to damage my phone.
Any help will be greatly appreciated.
Thanks.

I dont think its due to charging.. Do you take it with you in bathroom when you take a shower? Or maybe you sweated while it was in your pocket and it was hot outside?..
I had a LG flip phone years ago and the battery got so fat too.. The reason I believe was that it was in my pocket when I was outside and the temperature was like 45-50 celsius..

maybe, but at the time this happened the phone had been idle and out of my pocket for hours. i'll keep close eye on this one.
thanks.

Not heard of or seen this with Mobile batteries before TBH, however, this is "common" with overcharging of standard batteries in warping the cells etc..
I'm not tech enough to explain - but good call to keep a close eye, On the plus side, they batteries can be picked up dirt cheap on eBay or similar. Fortunately I have 2 as I returned my first Note after a couple of days and had it replaced, I just didn't send em the battery back

If you have warranty then why not go to samsung service center ? Bulging of battery is not a simple issue or sth which can be ignored . As a normal battery it should not bulge , I suggest you to go to SSC and get it checked , if there is some problem they will replace it ( I guess )

You should buy new battery, battery is cheap compared to phone.

there was a guy who owned a HTC Sensation and his phone caught fire whilst he was using it! it burnt his face.

Better buy an original Samsung battery from an official Samsung shop as there are many fake batteries online.....you never know if your battery is faulty or might explode. Better spend around 30-50usd on an original battery instead of being sorry afterwards.

That is simply because it got over-charged in the first case. Else might be a defect. A new battery can solve the issues. :good:

couple of questions regarding the note 5

hey, I'm here spamming with questions again.
1. is the back panel a gorilla glass 4? or just glass/sodalime glass/whatever else?
2. I think the battery in my note 5 is in bad condition. I have installed an app called Battery Doctor and when I charge it to 100% it says that the charge is 1750mAh. Clearly it is not even close to the 3000 the battery is rated at. The previous owner kept it under the charger for full 2 months, I guess that could be the reason its dying. I wanna know if the back is protected somehow because I dont wanna break it when I open it up, the edges are curved and I think theyre the weakest point of the cover.
3. is there a way to "heal" a battery that is in bad condition like mine? I tried to discharge the phone till it shuts down, boot it back up again and let it die again then charge it while its off to 100% but the rating in the app hasnt changed at all. still 1750mah.
thanks again guys

Cross check with another app. But even then, I don't trust them 100% for information like battery health etc.
The back is glass (not sure which type) and has a layer of shatter-proof coating underneath. If carefully done, it is possible to remove the back cover using a suction pull on the glass. There's a video where a guy mods his back cover to make it transparent and has removed the back successfully, you can watch that for reference.
Ever sine Note 7 thing, I'm not too happy with pulling batteries out of the devices due to accidental punctures :silly: :crying:
I am not sure there is any method of healing batteries. You need to buy a new one to replace the older one.

thanks for the answer. I tried formatting the battery but the capacity didnt change and the phone dies quickly. I found a replacement back here in poland for about 40$ +shipping so in case I break the original one I'll have a replacement and slap a dbrand skin on it so it doesnt look like crap. as for the note 7 thing, as far as I'm concerned note 5 wasnt as big of a bomb (pun intended) so if done carefully I think it might be relatively safe.

Battery reuse with screen + frame replacement?

So, my girlfriend dropped her S7 edge a couple times, and the screen is pretty ****ed up, although perfectly usable. the first drop has broken only the glass, but the last one broke a small part of the display as well, so I thought I could look up replacement procedures. It turns out that they seem to be pretty hard, of course. then i've noticed that they sell the screen with and without the frame, so I can gather that the main advantages of buying a framed one are: it could make the repair process a little simpler because i don't need to take the extra steps of removing the old screen and replacing it, and I wouldn't have to worry about a bent chassi screwing the new display - all that for like 15 bucks more or something.
but according to the ifixit site there's no way to reuse the original battery on the new chassi because the heat applied to the battery to remove it also ****s it up - except that in their own battery replacement walkthrough they also talk about a heat-less method of removing the battery by applying isopropilic alcohol to the edges of the battery to unglue it from place.
so I guess my question is: could I reuse a battery removed by the heatless method on a new chassi?

check your battery recharge cycle with samsung info app if it's more than 300 it is better for you to change it to have a better battery life. If it is healty one you can use it. Every service point they use the old one and all remove it with heat.

Has anyone replaced the v40 battery or had it replaced?

I remember when first run there was a system message that said don't attempt to remove battery. I think it's because battery is glued on and removal may cause damage to phone or injury to person.
Has anyone replaced the battery or had it replaced? What was your experience?
Thanks

Yes. Just did it on a v40 that I bought used on ebay. Battery had over 600 cycles and Accubatt was showing around 80% capacity.
Bought a new battery off of ebay for $12. Looked OEM except didnt have LG logo. Accubatt now shows 101% capacity.
Its really not that hard to replace. There are a few videos online that show how to disassemble the back. I was carefull and even reused the adhesive on the back cover, although i dont think id put it underwater anymore.

Battery replacement. Anyone has done it?

I'm unhappy with my battery life. While it did work 2-3 days with 4-5h SoT at best before I now get around 25-35% in the evening. Not suitable for another day.
So either the battery is done for or the software has become way way worse.

Battery Replacement does seem possible. So has anyone done it? Did it help?

Yes. I have done a complete screen replacement as well as the battery. I didn't need to watch out for a screen as it were completely destroyed. Yup, you're right about the battery, probably it needs to be replaced. I have a neat trick to help you with screen removal. Take a plastic bottle, cut a small rectangle from it (around 4x6cm should be enough) and then round those sharp corners with some scissors so there won't be any sharp edges left. Once you've that done, take your freshly cut plastic card and insert it into bottom gap (where speaker is). You could use a suction cup to raise the glass a little bit. And slice the adhesive around the screen. Ofc be careful not to push it too far to not damage screen ribbon. Watching teardown videos is crucial as you don't wanna pierce or rip apart the screen ribbon. if you want more information about this, feel free to ask As putting everything together - I recommend buying original lcd adhesive for xz2, it's simple and the screen stays on as well as original.

*#*#7378423#*#* go into this service menu then the battery health test, it tells you current max. capacity and health status whether if you need to replace or not.
battery replacement should be relatively easy since it is held down by screws not adhesive, be careful when opening up the phone you may damage the LCD also make sure you clean all the left adhesive residue before applying the new sticker or B7000 glue to the frame

I don't trust those numbers. That's the Problem here...
@Verity.
Did you realize any difference in Battery life before and after the change?

Certainly. I bought used battery as it was cheap and as the old one was quite worrying on the outside. I immediately noticed the difference (especially in sot) so with the new battery you should feel the difference even more.

Not sure if the degradation of the battery is good or bad...
After fully charging now:
And one of the earliest from 2018
https://forum.xda-developers.com/showpost.php?p=83337497&postcount=6

That's pretty normal. Every battery has a lifespan. It's depended on temperature, usage but the most important factor is the charging cycles. After x cycles battery loses it's capacity. It's due to chemical reactions inside of it and there's nothing you could do about it. Until solid state batteries will come out, you will have to change the battery once 2-3 years.

So yeah....
I've done it and i'm not happy
