Hi, I have searched and read the related threads in the forum about SGS2 charging issue. It is true that the phone charges really slowly compared to other phones. I just tried playing a game and charging at the same time and the result is the phone was barely charging, which I think is a ridiculous. It means the power consumption when playing a game is almost equal to power being charged.
How about everyone else's charging time? I read before it seems Samsung capped the charging rate at 700mA. Not sure if it's true.

Being a high powered phone, it consumes a lot of battery power when being used and very little when in standby. So if you want to charge it at full rate, don't use the phone at the same time.

Without using the phone, my average charging time has been 3 hours and 43 minutes to get from totally flat 0% to 100%. Normal daily charge from about 20% to 100% takes 3 hours.
The charging rate is capped so that the battery and phone does not over heat during charging. An overheating battery will expand and possibly explode, thus potentially causing phone damage and user injury. That is why the charging rate is limited.
Same as posted before zero to full about 3 hours .
jje
Same here...more than 3 hours for 0-100%...even this reduced charging heats up the phone..
KE series of firmware charged really slowly, but it was fixed after KE7 I think. With the latest KG3, charging from 0 to 100 is done in 2.5 hours with wall charger.
Also don't forget that this phone has a 1650 mah battery. Don't expect it to fill it up at the same time as a 1300 mah one found in most other phones.
i usually charge at 20%. i also get about 3 hours to full charge
I still think someone should increase the charge current and see how it fares. It's all about tweaking and testing.
Charge the phone turned off, that's the fastest way to charge it.
Well personally I think it's kind of counter productive if the phone can't charge properly when you use it at the same time.

So why don't you do it yourself and tell us how it goes?
Bump
Would be nice to see in Cog or Vill
So how much truth is in statement that you can't use navigation, listen to MP3s and charge via car charger because your phone will be discharging anyway?
I have the feeling my s8 doesnt really fast recharge even if it's enabled (i'm on 2nd charge now)... how long does it usually take you guys to charge it full when its very low, around 5%? And how long does it say it takes on the notification? Thanks!
About 1h50 or something with normal charge, not fast charge.

Mine definately took longer to charge than that the 2nd time (the first one i was asleep so i dont know) and with fast charge. Does it matter which side you plug in the cable or it's the same? I'm getting worried.
The side of the cable does not matter. I normally charge my phone when it's about 15% and with normal charge it takes around 1h40. Next time I charge it around 5% I will check but I think it's about 1h50 to 2h. My S7 was definitely faster in charging.
Takes about 90 minutes with fast charge
Around an hour and 20-30 minutes, a bit slower when I'm using wireless fast charging.
Did you notice a substantial difference between normal charge and fast charge? Lat time I checked it was about 10 minutes difference until full charge. I expected more, it was much better on the S7.
I think that fast charging got capped by samsung after all the note 7 exploding battery horror stories. And it got capped at 2.45amp fast wired charging and around 1.35 with fast wireless charging since the nougat update on the galaxy s7. when it was around 2.8 fast wired and 1.8 fast wireless charging on MM
Beside the charging rate cap, the fone is much cooler while fast charging now as it used to get crazy hot reaching temps above 42c while now it never gets over 36.smthing.
So while its slower i guess its a much better bet for the battery health and your safety.
Normal wired charging didnt change between MM and nougat and its around 1.7~1.8amp
These are my findings using the s7 and s8 exynos international versions and the statments above are purely my own opinion and experience which could be different for everyone.
I noticed that mine never goes over 1060ma while charging using Ampere. It takes about 1 hour 40 minutes to "fast charge" but it is cooler than any other phone I've ever had while charging.
The sad thing is that it REALLY takes longer if you are using the phone, like barely increasing its %. I even tried changing cables, chargers and places but now I know I'm not alone and this is how it works.
I have an Exynos.

IMO ampere is crap and slow to report, you need an app that can report as fast as cpufloat. As once you turn on the screen the charging rate will default to ~1amp regardless of the charging mode your using and thats when ampere starts to measure.
Use cpu float for info at glance
Or
Use accubattery to even help you distnguish which charging cables your using gives you the best charging rate.
Hope this helps

Back when I had my Galaxy S4 I used "CurrentWidget: Battery" which was really nice but is not working anymore so I installed Ampere.
I just tried both apps you mentioned and both gave me the 1050am right away. I'll try later on since I was at 90% and if I remember thats the point where it starts to throttle down the current.
I like the AccuBattery 80% cycle though, not sure I can really use it since I prefer to go with a full battery for the entire day.
Thank you!
Mine takes around 1hr 30 mins , The other night i turned fast charge off as i was going to leave it charge throughout the night but i actually forgot i had turned it off and had been charging for a few days with fast charge off..... surprisingly i noticed no difference! It still took around the same time to charge haha

You hit it on the nose. They slowed it to avoid the whole exploding battery problems just to play it safe. Also why they didn't cram a bigger battery inside it to keep heat down.
They lost a lot of money because of that. The only thing that really saved them was that some iPhones were blowing up too

Hi all!
Takes around 1 h 40 mins for a full charge. This is using the Fast Charger that comes in the box.

Bear in mind that the charging rate will default to 1050ma whenever the screen is turned on no matter what charging mode your using.
To use my method in cpufloat app, open the app n keep it floating on your screen. Turn of the screen for awhile ( lets say 5 seconds) and n turn the screen back on. You will have a split second to read the current before it updates to the 1050ma. ( you can slow the update rate in the app settings btw.
Accubattery will have 2 readings, charging rate when screen on, charging rate with screen off.

Yup, I noticed that, thanks!
Accbattery showed me a maximum of 1156ma obviously it was charging with the screen off. From there my test starts since this charge was done using a multi-usb charger and had something else charging and wasn't using the original cable. We will see
Thanks once again!

What other difference you want?
The charging issues on the Galaxy S8 seem to be widespread. I was hoping the most recent software update would help resolve these issues but it hasn't. Extremely slow charging (71% charged, 3 hrs 17 mins to 100%) and random connectivity (wireless charging paused) with Samsung's OEM wireless charger. What I've found with respect to the wireless issue, if I leave the phone on the charging pad after a few minutes it will eventually engage to a slow charge mode. Direct charging with the Samsung 2.0 Adaptive makes no difference, still a very slow charge. The normal Fast Charge Notification which should appear at the bottom of the display has never appeared and the tab remains grey in the Advanced Battery Settings even when enabled. Prior to purchasing the phone I had read and was advised by a Samsung tech the phone was suited to accept Qualcomm's 4+ Quick Charge. That seems unlikely at this point. Just got off a live chat with Samsung Support, not surprising the tech offered no solutions which I hadn't already experimented with. Booting up in Safe Mode to see if the app(s) were the problem, clearing system cache, app cache, using a variety of adaptives and cables, updating software, checking the C jack for connectivity. The S7 Edge I had previous to the S8+ was a great phone, no problems whatsoever. I honestly feel that Samsung is dragging their feet and haven't yet gotten their hands around these issues. Seriously, do they really want to experience another wide ranging battery concern? I think not. I can get a refund or replace the S8+ (SM-G955FD) but I'm wondering if the problems may be so widespread it could easily be an issue with the replacement phone. From the research I've done these issues are popping up on all models, regardless of the manufactures location.
My new 3 day old S8(exynos) stops charging randomly after 80%
Sometimes it's struck at 83% and sometimes even at 57%
Using stock charger with cable..If I remove the plug and restart charging it comes to full 100 percent..
And I feel it happens while charging with location turned on..
Kindly help..
Anyone else facing this ?
Has it been doing this from the beginning? After a soft reset the first thing I would do is boot it into safe mode to see if something I installed was causing the problem.

Thanks for posting the info you were able to get from Samsung on your end. I've experienced this exact same fast wireless charging problem stopping at around 79% to 80% and when I contacted Samsung via their online help chat support, the rep I got said that they've never heard of the problem being reported to them! I told him that the problem is being reported all over the various internet sites and forums. He still denied it. Anyway, I've put a link to this forum thread in the other forum thread reporting the same problem. The overheating safety check that stops the charging makes sense to explain what we are all experiencing however I think it is a flaw and defect since it fails to allow fast wireless charging to charge our phone up to 100%. We will wake up in the morning late for work and the phone will not be 100% charged? No time to wait and recharge it to 100% when we have to rush out the door to go to work! I can see all the upset users!
Tested mine on Samsung original Fast Wireless Charging pad. When temperature more than 40°C then it will stop charging, you can monitor your phone temperature using 3C battery monitor widget. However, the issue is its temperature won't go down when it's sitting on the charging pad & make your charging halt until you take out the phone & let it cool down.
My solution is simple, use a USB fan blowing it when it charging wirelessly & its temperature didn't shoot up more than 38°C.

What gets me is that Samsung advertises that these charger docks have a built in fan that is supposed to keep the phone cooled. But the fans in these docks don't even blow on the phones at all. The placement of the fan vent holes are on the back of the base which serves no purpose cooling the phone itself. Dumb.
Here in India temperature reaches 44°C during a normal day...
Hence my phone stops charging all the time !
Pretty irritating..hence I am forced to use the mobile in an air conditioned room always..
Don't know if my particular unit is overheating..coz very few are complaining here in india..and Samsung is not accepting this as a fault and not providing replacement !
Can someone post their battery temperature during
1.Normal usage ( social apps with some Spotify)
2.Youtube in FHD with 100% screen brightness with video enhancer turned on for 8 to 10 mins
3.Fast charging
Mine is
1.38 to 40°C
2.43°C
3.More than 45°C

Same issue with my Indian s8 plus on charging pause at 83%
Hi I Am also having the same issue with s8 plus .It stops charging at 83 % and if disconnect the charger for a min and reconnect it goes to 100 otherwise it sits at 83 % for whole day if I didn't replug. Hope it is a feature for safety. I Am getting 14 to 17 hours of battery life for 100% .so great battery management and safety by samsung great.
Good for Sammy was wondering why this happened

The question really is why is it getting so warm when the phone is idle and charging? It normally stays cool.. so why on one random night did it get too warm..
There are clearly 2 problems here
Why is it getting too hot in the first place (assuming a country that does not have a very high ambient temp)
Why is it not doing what it is clearly supposed to be doing and continuing to charge once the temp goes down (as Samsung themselves have apparently said, it should continue to charge once normal temps are achieved but it is clearly not doing that)

That would seem to be a serious problem. If it is stopping the charging due to the heat, and stopping it does NOT stop the heat then this "safety" feature is completely failing to work. It will sit there being too hot for endless hours, which is surely a big safety issue (else they wouldnt stop it charging in the first place!).
As if that wasn't bad enough, heat is bad for batteries, if its sitting there for hours not charging and just generating heat, it will be sitting there too hot for hours on end and degrading the battery.
Ironically if it just kept the charging going then I assume once at 100% it would actually stop charging and reduce the heat (although perhaps this doesn't work either and it also still stays hot??? this probably needs to be checked too, we don't want it sitting there staying hot even after it gets to 100%!). So in the current situation it would actually be better if it DIDNT stop charging so it could get to 100% and cool down instead of sitting there at ~80% and staying hot!
I have the new samsung convertible wireless charger and have not had it do that so far but I am also in the UK where it is not exactly hot anyway (we will see what happens in summer!).
The final question is has anyone had this happen when charging with wire?

i've had mine just over a month, and most nights i wireless charge, all but one night it has charged without issue, to 100%, and it was cool when i woke up in the morning
the only weird thing i noticed at the time when this happened, was that after I had picked the phone up, and put it back on charge, it said 'Fast wireless charging' - yet in settings>advanced>accessories, fast wireless charging was disabled.
I re enabled this, and it hasn't happened for the two nights since. but i don't know if it was related or not really.

have this problem with a fast car charger from Samsung...stops at 85% and dropping with the charger connected... yeahh the phone was hot because of the navigation maps......(( dam they need to fix this crap
on my s7 did not had thia problem
---------- Post added at 11:36 AM ---------- Previous post was at 11:34 AM ----------
did not find nothing on the internet about
Swelling Prevention Mode
From India, I had the same problem while charging off the official charger but I thought that's normal since my M8 "Using QC2.0" also charged very fast til 70-80% and then slowed down quite a lot but the S8 almost stops around a similar mark and then sort of trickle charges the rest of the way.
Had I to guess I would say that between the S8 and the M8 the S8 would take much more time to reach 100% from 80% than the M8
they don't test the phones they crap

From INDIA..Here summer is at its worst temperature reaching 42 celcius..It happens all the time with the stock wired charger.My phone never charges beyond 84% except if I am in an air conditioned room..
And also fast charging never works..Takes 2.45 hours from 3 to 100%
Worst samsung !!
Hi, I've been using Huawei p10 lite for more than 6 months, the phone used to charge in about 1 hour and 30 mins but it's been a month my phone now charges from 20 - 90 percent in about 3 hours.
Phone charges fast when i shut it down and charge.
I've tried Factory Data Reset and I'm using Huawei Original charger.
The temperature of my city is 46 degrees Celsius.
I'll be glad if someone assists me.

Well, if the ambient temperature is 46 degrees then there's your problem.
If you've got air conditioning, then it's not.
The charging speed should start to drop in the mid to late 30s (that's temperature and of course battery temp specifically).
Both extreme heat and extreme cold are bad for your phone and the battery in particular. 5-25 degrees is probably the ideal operating environment but that's obviously very hard to control and the phone is rated to go beyond that but as I said: not ideal.
Better for it to charge slower than risk explosions if you ask me
Same issue, but lower ambient temps and not always with the original charger but a charger that supports quick charge either way
Device is up to date and not rooted, but heavily used

If you mean Quick Charge, then that's a Qualcomm technology and would not work. I think Huawei uses a proprietary protocol on their phones but from what I can tell it isn't their Supercharger tech either.
You're only really guaranteed those speeds with the original charger or a charger certified to work with your phone or its charging tech. You may be able to get it to work with a charger rated for the same ampere/volt spec but I won't guarantee it as there's usually more to it than that.
That's why proprietary technology with competing standards suck. It's hard to find something that works.
Anyone facing heating issue while charging with stock charger? Is it only me or anyone else facing the same ?
Temperature goes upto 45°c ..is it normal ?

i'm using the default charger (out of box, 5V 2A) on RN7 (chinese rom), battery doesnt heat up as the app (AccuBattery) saying temperature upto 36 or 37 C, once i seen shooted at 39 C (max)
but in any case phone was slightly heated on top from behind (adjacent to back camera), i think it may be due to processor but the battery temperature was fine

Battery temp depends on ambient temp too. It's about 36°c ambient here. So may be that's the reason for heating.

i think it is not normal if ambient is 36 and on charging battery temp goes upto 45, you can also check different phones with different chargers
or you can try charging your phone via laptop/PC, it will slow charge the device but you will see the temperature rise of battery be negligible
keep in mind that charger as well as charging cable both may contribute in heating up of phone
by the way which charger are you using?
just for information (not related to thread) you can visit the website regarding temperature and battery life

Thanks for Ur reply.
Yeah, for high ambient it's ok to have high temp. I thought the same.
I am using charger that came with the box.
Saw many people complaining about the same. So thought of creating this thread.

keep in mind that im using chinese rom (comes with the mobile), lucky me my mobile dont get heat up, same is the case with my friend we purchased the same RN7 chinese and both got lucky because mobile isnt heating while charging, although im thinking to purchase QC4 charger but don't know will it improves battery life (cycle) or degrade it at the cost of fast cahrging

A custom kernel could be a solution for heating, or just charge at lower amps.
Reg. Qc4 make sure u charge in an AC room ?lol

I dont think QC 4 require AC room, as my friend owns vivo v15pro with fast charging (5V, 4A). no heating issues, im concerned because RN7 is a budget phone and normally budget phones dont offer QC3 or QC4/+

Redmi note 7 is QC 4 certified by qualcomm.
See image attached.
thanks for the reply, i am still confuse because of the budget phone, i will try QC4 charger sometime later, let see what happens
