A few weeks ago I noticed my phone wasn't charging at night. At first I assumed it was either my charger or charging cable as their both cheap ones from Amazon. But using my Anker battery pack or the stock charger setup didn't help. Then I noticed on nights it wasn't too cold, it would charge just fine. At night I like to sleep with my room being as cold as possible and here in north Texas it's been getting into the low teens. The phone not charging at night isn't a huge deal as I can just charge in the morning after the phone has been in my pocket for a while. I'm just wondering if anybody else has experienced something like this. I can't find any info on the S7 or S7 Edge, only the S6. And I'm not getting any notifications that say the battery temp is too low or anything like that, it just doesn't charge.
I'm pretty sure there isnt a battery temp too low warning lol. I only know these batteries likes to be charged when its warm cause it allows it to charge faster. Anyone want to put their phone in the freezer and try it?
galaxy S8 too cold won't charge
I am a 3rd party phone repair technician, I had two Galaxy S8+'s come in today with the same issue you described.
They won't turn on with the charger plugged in and if they are on they display a message about the battery being too cold and won't charge.
We have had the same issue on s6 and s7's that have been water damaged however cleaning the board with distilled water and ultrasound to blast minerals off fixes it.
The part that stumps me with the s8+ is both phones are not water damaged and have never been exposed to moisture...
A new battery does not fix the issue and the charge port and other components are immaculately clean.
If anyone has a solution for this issue that seems to effect the S6,7, and 8's I would be very interested.

So I was charging my phone last night and it was under my pillow on airplane mode as usual, because I use it to track my sleep patterns. But this morning I woke up phone was off, with the charging battery icon showing only, and was so hot to the touch I literally couldn't even pick up the phone. I was really surprised it didn't melt or start a fire, that's how hot it was.
Now today after letting the phone cool down, it doesn't seem to be taking charge well at all, I'm having a very hard time getting past 25%, if I use the device while charging it will actually drop charge while in use (and this is with the wall charger).
I'm thinking the battery cells have been damaged by extreme heat. but just wondering if anybody else had the phone get this hot?
Sounds like damage to me! Sorry to hear that man.
Also seems like an irreversible damage to me :/
Some day I accidentaly left my LG GT540 letting it charge under my pillow. It got EXTREMELY hot and I unplugged it swiftly; I was so frightened that the battery (Li-Ion!) might have literally blown up.
To be honest, you should be grateful that your pillow didn't catch on fire together with your head, really... NEVER EVER LEAVE YOUR PHONE CHARGING UNDER ANY PILLOWS!
Well guys funny thing is, seems to be charging ok now.
I believe I'm having a similar problem that a lot of other people are having with the phone getting stuck on USB charging mode even with the wall adapter, so not accepting ACpower. But once I reconnected it a few times now its charing on AC and got back up towards 70%, so I think luckily I might be ok.
But damn this phone gets so much hotter than the galaxy nexus.
My phone never gets hot when charging...ever. I think you might have an issue with your phone
Hi
Recently (no matter what charger I use) it gets incredible hot. The phone is just "normal" when charging. The thing that gets hot is the end that you put into the phone. When it reaches 100% it stops charging and cools down., so it doesn't overcharge.
It do not get hot when I use my wireless charger either, so the problem is only there when I try to charge my phone directly. If I fast charge it goes fast, but get incredible hot and if I turn fast charging off i'm lucky if the phone is fully charged the next morning.
Any idea what this could be? For now wireless charging is my only option.. Fast charging is too hot and turning it off result in over 10 hours to fully charge.
I have tried changing rom, clear everything, changing kernel, stock, modified and so on..
I had the same issue as well. I've seen some people reported that they fried their charging port because of that. I called Samsung and they gave me a replacement charger. Haven't noticed any issues with the new charger yet. So, my advice is get a replacement charger.
Samsung replaces faulty chargers with no major obstacles from the buyer's side - if you have Samsung's warranty service nearby, they will replace the charger right away.
I have the Samsung official wireless charger that I got with my S7 Edge. Was using it on the S8 fine for a couple days when all of a sudden it won't charge to 100%. Day one it stopped at 84% and this morning it wouldn't go past 76%. The phone is pretty hot when I pick it up and the LED is lit yellow the whole time indicating it's being charged. Did a search on here and it seems like some people are having some problems with wireless charging but not exactly the same as me. Anyone else have this issue?
are you using the original samsung charger plug that came with the phone?

No, it's the original micro USB fast charge plug and wire that came with the S7 wireless charger.
This one
http://www.samsung.com/us/mobile/mo...charging-stand-black-sapphire-ep-ng930tbugus/
Im using a QI dock myself. Works fine here. 100%
Now I do remember some of the Samsung ones from the S7 were able to support the "Quick Charging" function. Which was designed to get it super fast to "x" % then switch to normal charging. So its possible your issue is something related to this.
It's weird because it would just stop at a random number. Even taking it off and rebooting then recharging doesn't help.
I remember reading on the Chip Binning thread about some people talking about bad chip bins causing battery problems and you may wish to consider getting that exchanged.

Well last night it stopped at 87% so in half sleep rage I took off my case and had the bare phone on the charger. Later on it was at 100%. I also have my work keycard in the back of the case which I'm not sure if that makes a difference because I had it in the case of my V10 and S7 Edge and they were able to charge to 100% with the card and case between the phone no problem. The case is just a regular thin case from eBay. Also pretty strange that it would stop at a random number. Gonna do some more testing tonight.
I use a thin gell tpu case on mine, I have a Mikobox QI dock as well.
Now stuff behind the case, that "could" maybe mess with wireless charging. Never tried with stuff inside my case.
I have had this problem too. Wireless charging stopping at a certain percentage.
Worst this morning as I woke up to 8 hours on charge and it was only at 56% still saying it was wireless charging!
Thinking about trying the official Galaxy S8 wireless charger
I'm using the samsung fast wireless charger that i bought from when i had my s6 edge+
I'm using a tpu case on the phone, works perfectly fine
fast charge doesn't work without the genuine samsung charger plug however
Had my regular rubber thin case on with the card inside last night and it charged to 100%. Really don't know what's going on here anymore. ¯\_(ツ)_/¯
Try an old lower amp wall wart with the non Samsung wireless charging platform. You will not have fast charge, but it will go to 100 percent.
Same issue here. It used to work absolutely fine and got to 100% every evening. Now it stops around the same amount every night. 80% ish
I have only noticed this since the last OTA update and its a nightmare. The phone is super hot and showing as charging wirelessly but it isnt. One thing I did try was to let the phone cool down and turned off "fast" charging wireless. Only when the phone had cooled down did it start to tot up again.
I have also had the odd warning saying that it wont charge any further until the battery cools down, which makes me think this is a "safety feature" that was implemented with the latest OTA rather than a fault, but not all of the time. It seems the message will pop up and then go away quite quickly (probably as to read the message I am knocking the phone off the "sweet spot" that charges it, so it doesn't feel the need to show me the message anymore)
Try letting the phone cool and then put it back on and see if the numbers rise everyone and maybe we can workout together what the problem is. That's my thoughts so far s that the phone is charging fine, heats up too much, stops charging, cools down, starts charging again, heats up etc etc.
Guess the end result of the story is. The S8 doesnt like to be "Quick Charged" via QI pads with the higher volts.

but it isn't, because a lot of people have fast wireless charging working just fine?
Update on my last post. I have fast charging off and last night I popped it on the charger when going to bed. Woke up about 4am to use the little bits room and there it was stuck on 81% as usual and very warm. Took it off the charger and went back to sleep. Woke up again about 7:30 and the phone had cooled down so put it back on the charger. By 9:45 the phone was at 100%. Looks to me like it is a heating up issue on mine anyway.
I get the problem too, the wireless charge of the original s8 package and use the skin case, when the first charge only up to 84%, after being released and cooled for a while then in charge again can finally be 100%, the possibility of problems in excess heat due to wearing a skin case or indeed a problem from Wireless charger, I do not know yet
Got the same problem here!
until now (about 2 months) im using allmost only Wireless charging (original samsung charger and cable)
untill today the Phone stop at 80% and its says that it still charging.. i took the phone of from the charger for about 30 second and put it back on charge and it charging ok...
Same problem. S8+ Exynos.
I'm using the wireless charger from the starter kit. Wired charging is fine and takes about 1.5+ hours from 5% to 100%. With wireless charging, the estimate is usually 2.5 hours but it stops at 80+% after about that time. Charging continues if I remove the phone and place it back on the charging dock after a few seconds. Having a case doesn't seem to matter.
Just now, it finished charging wirelessly with the phone off. It went to 100% but took 3 hours. I did check after 2.5 hours and it was at 83%. I didn't remove the phone from the dock.
ok so i've had this phone since 20/04/17
it's been perfect charging, until this morning
was quite warm, and stuck at 83% - had been at that level for a couple of hours....
weird
i had fast wireless charging disabled in settings>advanced>accessories - yet when i put the phone back onto the charger it said 'fast wireless charging'
i enabled it, put it back on charger. fast wireless charging again..
disabled it again, put it back on charger.. still said fast wireless charging !!!
so i enabled it again, put it back on the charger, went back to sleep for an hour and then it was at 100%
will keep an eye on how it goes the next few days

did you disable fast wirelss charging in your settings menu?
my theory being that if that were disabled, but still somehow fast wireless charging, maybe the fan wasn't on but it was still fast charging = excess heat?
Could my work on my XT1575 cause the phone to charge very slowly? As long as I was using a good QC3 charger and a QC3-certified micro USB cable my MXPE phone charged fast. I have TWO working XT1575s. When plugged into the same charger with the same USB cable they both showed "Turbocharging" and both charged quickly.
Last week I replaced the back of one of the phones. -- exchanging the original back with an ebony wooden back. I had problems getting the ebony back to stay completely adhered so I installed it, removed it, installed it again with better adhesive. looks fine now.
Now, the back is securely in place BUT THE PHONE WON'T CHARGE FAST ANYMORE. Could I have damaged something in the phone while doing all that heating during the back replacement? I use a heat gun, always on the low setting, but I for the last installation I moved the heat pretty slowly around the back to increase the heat and hopefully improve the adhesion.
Everything about the phone works perfectly, both hardware and software. When I plug in a charging cable is shows "Turbocharging" but the charge time estimated by the phone is 7 or 8 or even 9 hours. That's about how long it takes too. And the phone won't charge past about 90%.
I've already replaced the battery. I have no idea how to further diagnose the problem. Have I effectively destroyed my phone while putting on a prettier back (to summarize how stupid I'd feel)?

Either you have a cheap low quality battery or you probably burnt it up with the heat gun. The NFC pad is on top of the battery if that still works then I highly doubt anything else was damaged but I could be wrong. Worse case scenario you desoldered something on the motherboard but I doubt it. First check the wattage on your wall charger if it says 5 volts and 1 Amp then that's your issue. Most wall chargers or USB ports I use have to be at least 5 volts and 2 amps or it will not charge and it'll actually get stuck at 90% like in your case because the charge rate slows down after 80% I believe and a crap wall charger won't have enough power to charge the phone like a high quality OEM wall charger would.
Hello all,
this is a rather strange thing that recently happened: my dad's galaxy S7 edge which has been working completely flawless the last few years recently decided to just turn it self off. He handed it to me saying it was working fine last night and trying to use it next day absolutely nothing happens anymore.
I tried to charge via USB with Samsung charger, wireless charger from Anker in case the USB port is defective, and different key combos to restart etc. On PC nothing is detected either..
Could a faulty USB charger have killed the device? When plugging it in, there is absolutely no sign of life - you can hear a faint "buzzing" but no indicator lights etc..
Does anyone have any tips? It would be really appreciated!
Battery or port pcb failure. Maybe both.
Replace battery as it's long overdue.
Once an Li reaches 80% of its original capacity it's reached the end of its usable lifespan.
It's degraded at that point. Degraded Li's are more likely to fail. Any swelling is a failure; replace immediately if observed.
Replace battery and go from there...
Thanks @blackhawk for the tips and insight - I will try to replace the battery!

On a heavily used device the battery lifespan is typically 1-3 years.
I plan to replace my N10+ device's battery about every year, routine maintenance.
A failed Li can do a lot of damage. It rests on the display... which is somewhat fragile.
Get a new rear cover seal when replacing the battery so it retains its water resistance. On AMOLED (NOT LCD displays!!!) displays anhydrous isopropyl alcohol can be used to help loosen the double sides tape on the rear cover and battery if you do it yourself.
Controlled heat is used to help loosen the rear cover on most of these phones. Many shops will replace the battery for a low price as well.
Pretty amazing stuff right here. My S7 Edge did the exact same thing last night.
Think Samsung hit the kill switch.
I'm writing this message from my dad's s7 edge which has kinda the same problem but it's still usable. It shuts down suddenly (even with battery full 100%) and the only way to turn it on is plugging it to the charger, otherwise no sign of life.

I believe, most of this case was caused by power IC, my s7 edge was suddenly died last night too. You can see on this thread and tutorial.

Yeah, i want to try this too, but i think it cost too much money, not worth for me. And also i dont trust to much for 3rd party repair on here except samsung service center.
But u can give it a try. Hope it works.
