hey there..
got my S2 yesterday and had a wave before..
the accu is charging very slow..(from 19% - 100% about 3 hours)
and while it´s charging and i do something with the phone, or without doing sth, too. i become very hot..
is it normal?
newest firmware is on the phone..

well without telling us what temperature you are reaching we cannot really say, but the phone will get hot if you use it while charging, especially if you make a call while charging.
don´t have opportunity to know what it is exactly..
when i touch if feels like a cup of tee at the time you can drink it first..
what about the charging time?

This is pretty normal, Li-Ion-batteries can´t be charged fully under 3h. Devices that claim to charge the battery in just 1 or 2 hours will charge it only to about 80% and then tell it is fully charged.
You can charge a Li-Ion-battery very fast from 0 to about 75-85%, if the power-adapter delivers enough energy this can be done in about 1h.
But to fill the rest up to 100% you need another 2-3h.
Li-Ion-cells are charged in 2 stages.
In the first stage charging is done with a current between 0,5C and 1C. C in this case means capacity, so our 1,6Ah-battery will be charged with 0,8-1,6A.
The voltage of the cell rises from about 3V when completely flat (you shouldn´t discharge a Li-Ion-cell below 3V or it will be damaged permanently, when discharging below 2,7V the cell becomes unstable and could explode when being charged, therefore a safety-circuit should prevent any further charging when the cell-voltage was too low) to about 4,2V.
When the cell reaches 4,2V it is charged to about 75-85%.
If you would charge further at this rate, the cell-voltage would rise even more and significantly reduce the life span of the battery.
The supplied power-adapter delivers 0,7A at 5V, so with some quick calculations it will not be able to charge the battery up to this stage below 1h.
If all the power from the adapter can be used for charging (which means no other phone-activities which will consume power) it can reach the saturation-stage in approximately 1,5h.
To completely charge the battery stage 2 follows, this is also called the saturation-stage.
During this stage the charging-circuit will hold the cell-voltage constant and reduce the charging-current accordingly.
If you want to charge the battery completely the rather weak power-supply doesn´t matter that much (at least as long as you don´t use the phone otherwise and take a significant amount of power away from charging). The faster you charge in stage 1, the longer the saturation-stage will last. The whole charging-time is not influenced a lot.
To fully charge the battery you will always need about 3-4h. Also the difference would not be great whether you begin charging at 0%, 20% or 30%.
Charging the first few % will always be very fast and gets slower the fuller the battery already is. The saturation-stage will take about 50-75% of the overall charging-time, so there is no significant difference whether the battery is completely flat or still has some charge left.
and while it´s charging and i do something with the phone, or without doing sth, too. i become very hot..

Are you just charging the phone or using it the same time? If you are just charging it, it definitely shouldn´t get hot, charging Li-Ion-cells has a very high efficiency-factor (about 95-99%), so there shouldn´t be much heat generated from the charging.
If you are using it the same time, it is pretty normal that the phone is getting warmer.
It is also important what is getting hot. Is it really the battery (the lower half of the phone) or rather the SoC (which seems to be placed just below the camera)
If it isn´t the battery, it can´t be in direct relationship with the charging. If the whole phone is getting warm, it is an indication, that the SoC is doing some work and generating the heat.
If only the battery gets hot (and not just slightly warm) this can be a problem. Either the charging-current is too high (quite unlikely, with the weak power-adapter) or something else is wrong, which will at least cause a shorter life-time of the battery.
It is normal that the battery gets a bit warmer than the surroundings, especially if the battery is in the early phase of stage 1, where it is charged pretty fast.
While the charging will not produce much heat, the battery is in a plastic-shell, so it can´t be transported away that fast.
But if it gets really hot you have a serious problem. But I doubt this, the phone actually has a protection, that will not charge the battery above a certain temperature-level.

If battery gets a little bit hot, it's normal, if you get hot then i don't know
I charge my phone overnight, from around 10PM to 8AM, then I leave my phone charging in its dock from about 9AM to 5PM during the work day...
any harm in doing this? I'd like my phone to last quite a while, as we are currently in a serious relationship, and I don't plan on letting her go....
What hurts your phone battery is not charging it but keeping it on high temperatures for a long time. And guess what keeps it on high temperatures: yep, you guessed it, charging for a long time.

While it always depends on the charging circuit, keeping your battery topped up by constant charging (even trickle maintenance) will reduce the voltage level that it can be charged to. This will take quite some time to notice, and several deeper charging cycles will "repair" this to a certain extent. But with any battery, keeping it any constant level will reduce its charging capacity, and continual charging (trickle or otherwise) will "cook" the batteries chemical make up sooner.
To do what you're doing everyday will absolutely have an impact on your battery's health over the long term. But to exactly what extent is based on several factors I don't have specific data on.
Absolutely, our phone battery is designed for mobile usage, not to be tethered to a charger constantly. Constant charging is unnecessary, wasteful and leads to early battery demise.

And aren't our high end modern phones also designed to trickle charge when it gets to %100, so no harm can come to it?

I suppose it depends on how you define "harm". Read my post above again. Any level of current that is continually supplied to a charged battery will accelerate the aging of it.
Even if the charger were to shut off completely, and then resume charging at a certain level (which I believe is the behavior of the LG wireless charger at 95%), continually discharging and recharging from 95% to 100% is probably not ideal.
But all of this is probably not all that great of an affect in the grand scheme of things. You're not gonna kill your battery in a matter of months by leaving on the charger all of the time. Yes you will accelerate the degradation of the battery's health over time, but if your phone is in use enough so the battery is being discharged regularly between charges, I doubt that you will notice it for a long time, if at all.
I can say that if you simply leave it charging 24/7 without any other kind of use you will be able to measure degradation surprisingly soon. As to how noticeable it will be is very hard to say.
I use and suggest Battery Monitor Widget from 3c. It takes the guess work out of what you see when you're charging and what happens to the phone when it reaches 100%.
As the phone gradually reaches 90%, charging is noticeably slowed. From about 92-100% it trickle charges from around 300 to 200 to 100mA until it reaches 100%. Charger stops charging when full and lets the battery level drop slightly before charging it back to 100%. You're constantly topping it off at full and batteries of this chemistry don't like that.
As far as I can recall, these types of batteries actually thrive on being run down and cycled back up. The only catch is, don't run them down until it's completely dead. You've significantly cut the life of your battery if you do it quite often.
To answer your question, it probably doesn't hurt that much. If you do it for months, maybe years. Yeah, you'll see some degradation.

I would correct this and say the battery loves being near the median. Store at 40% battery! 100%-0% is bad... 100%-10% is better, 90/10 is better etc...
80/40 is really good for preserving charge cycles. Basically, charging at 30% back up to 70% is better than letting it go down to 0%
Note: this is a REALLY good battery in this phone. Just USE it until you feel it's dying too soon and buy a new one. Batteries are cheap and will be cheaper in 2-3 years.
But we can't buy battery for this phone.. I always let it run down to 14% that's when the warning message pops up.. Then back up, charges in 2 1/2 hrs then I leave it on an hour more until I leave from work so I could have a full phone.. Note, I work over nights, so its dead at around 2 or 3 am sometimes, then I leave at 6 am..

Most of us in here don't keep our phones long enough to notice any battery degradation..
Just charge it as often as you can but unplug it when it's full.
To be safe I would let the phone idle off of the work charger and only plug in at home.

Agreed, I only charge once a day and it's usually sufficient, if your a heavy user and are concerned about the phone dying at night, let the phone decharge normally throughout the day and plug it in an hour or an hour and a half before you leave, however long it takes to charge the device after a workday's worth of usage (Whatever that is for you)
I do this myself if I'm using my phone heavily during the day and know I'll be out all night. Like some said you'll probably never even notice the degradation, but when you know it's not good for the battery in the strictest sense why risk it, the phones aren't designed to be charging 2/3rd of the time, they are designed to be charged and then taken off the charger and used.
Do you let your battery drop down to 5% before connecting the charger? Or do you charge every moment you get the chance to keep battery at max?

Battery łasts a long time as it usually goes off the charger at 7 a.m. I charge it while sleeping. Occasionally out of habit I will charge it while I'm driving in the car but for about 15 minutes. Otherwise, I am very happy with the battery.

I'm not an expert, but all I've heard is charging over night or after it hits 100% is bad. Why I don't know, but I try to charge my phone when it reaches everywhere from 15-30 to 95-100 then remove the charger.

I'm not constantly on my phone, so usually charge it up to 80% and recharge when it drops to 40%. I only charge it to 100% when I am out and about for the whole day. See the following link for charging advice:

Nah, that's old news. Modern chargers and devices know when they've hit 100%, so they stop charging at that point and lets the battery dip down to 98-99% before trickle charging up to 100 again, and so on until you unplug. It's completely safe, and you shouldn't trust all those garbage click-bait articles out there. Do not, however, go down to 0% before you recharge it. That can actually damage the cells in your battery, so plug it into the charger before that. If you notice some funky behavior from the battery, like if it's jumping from 30% to 20% in five minutes, or is stuck at 10% for an hour, then it's a good idea to completely drain it to 0% to calibrate the battery since the OS has no idea how much battery is left (so it knows where 0 is again). This will usually happen after flashing a different ROM. Charge it up to 100 again and it should be back to normal.
I personally charge it normally at night, without quick charge, since there's no point in having it quick charge while I'm a sleep for around 8 hours. I'll only quick charge it in the middle of the day, which is almost never, since the battery is freakin' awesome.
Don't worry about the battery too much, but don't reach 0% too often, and you'll be good. By too often, I mean every 3-4 months or so is OK. I base these things from my Sony device which I've had for almost 3 years. The (sealed in) battery was very good out-of-the-box, and it's still very good after nearly three years, so I won't mess with a proven success.
To be safe on the longevity of the battery I use one of these with my wireless charger :
http://www.amazon.com/gp/aw/d/B003P...mer+outlet&dpPl=1&dpID=31OAEbif0lL&ref=plSrch
My battery is usually around 30-40% at the end of the day. I use the regular speed Samsung Charging Pad and set the timer on this outlet for 3 hours when I go to bed. So after 3 hours it stops charging and I don't have to worry about the possibility of damaging the battery (I know about trickle charging, but I think this is better)
Ive read somewhere that the new s7 edge charger doesnt have a power inverter so it keeps charging and wasting power which could damage the charger or possibly device. So know if thats correct.

I just purchased one of those...thanks for the advice. I charge my device when get around 20%-30% of battery and left charging over night ( when sleeping) on my standard Samsung wireless charging. My battery is just ok.. I'm not so heavy user and sometimes I have to charge around 8pm or so. I take off from the charger at 100% all morning around 8am.

At home. I do wireless when ever i can. If im not using the phone then i sit it on a wireless charger.
Battery hasnt drop pass 30% in the week i had the phone.
My note edge would drop pretty low because i didnt use wireless charging. So my phone would just sit in my pocket slowly draining.

Whatever you read, either you misunderstood, or the person that typed it was a bumbling idiot. A power inverter converts DC power to AC. Your source/utility power is already AC. A USB charger is merely an AC adapter made for USB. The phone has integrated circuitry that controls when and when not to charge the battery and at what amperage.
I usually let mine get to around 5% everytime. Then charge it back fully to 100%.

Not at all, but just try to not discharge the battery completely to the point where it turns itself off. It won't ruin the battery to the point where you actually notice it there, but it's better if you just turn the phone off if you're able to (unless it's an emergency, of course).

Does it hurt the battery to charge the phone with a different charger ?
Sent from my SM-G935F using Tapatalk
I never used the fast charging, I think that slowly charging a battery is better for the lifetime. Most of the time it is below 10 % before I plug it in and I also want it to be at 100% and ready (green LED) when I unplug it.
my note 3 battery is still superb and I got the phone since 2013
Best way to keep a battery in good health is to charge it to full before you start using it. Also, try and never charge it until it's less than 50%. Charging it overnight is perfectly fine it won't hurt anything but once ina while, at least say once a month let the battery drain all the way, try to turn it back on if it goes off sometimes there is still some juice left and it might start up, once it won't start anymore try and charge it without turning it on to full. I wouldn't do it more than say a couple times a month any more than that is overkill and may do more harm than good. These are the guidelines I use and I have never had battery issues. I currently am waiting for my S7 Edge and on my Nexus 6 I usually get 48+ hours with 4+ hours SoT. I'm just an average user currently.
Is anybody having slow charging problems when the screen is still on?
A couple of days ago it took over an hour to charge from 5% to 25%, all I was doing was social media browsing. As soon as I put the phone down with the screen off the % jumped to 85% in around 30 minutes. I took my V20 back to the LG shop and in the end they replaced the unit as they could see the problem but was unsure what it was. They then tested the new one just before I was leaving and it was again taking nearly 90 seconds or more to charge 1% on the new device straight out the box. They went and give me a new battery and said to test it out for a few days before going back to them. It was there first complaint about the charging speed.
Again, while not using the device the charging is quick on the new device, but slow when the screen is on and in use. I will give it a couple of days and take some screenshots of the battery stats if it continue. It did say on my old device while connected that it was 5hr 45min until fully charged which is obviously wrong.
No weird apps on there that could be causing it as far as I'm aware, unless it's an LG pre-loaded one.
Strange that the new phone is doing the same.
Sounds like that's how the V20 manages battery charging. It charges faster with the screen off. And a lot faster with the whole thing off.
Same thing happens to me. When using Waze app. Even if it says fast charging, its noticeably slower than when i had my note 5 or 7.
Maybe its "heat management"? Im just guessing. Maybe to prevent it from heating fast with the screen on + quick charge
I think it's QC 3.0 - it does it so as to not overheat the battery. I have it happen on mine too when using a QC 3.0 charger.
When using a QC 2.0 charger(Samsung charger) it chargers a bit faster while screen on but the phone starts to get noticeably warm.
It is probably a thermal management thing. My N6 Shamu got very warm on QC2 with screen on.
The v10 does the same thing it's probably because the screen is the biggest battery drain on the phone so using it obviously would cause a significant charge delay.

Normal.
Hmm. I notice charging is slower when it's the temperature is higher.
I just bought a Spigen Rugged Armour case and I think it's trapping heat during usage. And when I start charging, it's not as quick as I had hoped.
I'm going to observe a little more.
Alright. I've done a few days of observations. It definitely charges a lot slower when the screen is on. I used the Ampere app and it charges around 900mAh max, screen on.
When it's off, it averages around 2800mAh, depending on temperature too. Once it hits close to 40 Celsius, it drops to 2000mAh or lower.
With the phone powered down, it charges faster than just screen off. How much faster, I am unable to measure without using some special hardware.
Overall, I'm quite pleased with the charging performance.
Turn your screen brightness down. Also I noticed restarting the phone helps with it to charge faster. Could just be a glitch in charging software

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

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.

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.

About 1h50 or something with normal charge, not fast charge.

I don't see a big difference between fast and normal charging. I only fast charge when I'm in a hurry.

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!

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.
