Hey, thinking about buying the new fast wireless charger. Can someone who has a fast wireless charging pad tell me how long it takes to wirelessly fast charge the phone? Thanks
Mine takes around 3hrs to fully charge S8 from 10%
But I find out that wireless charging is much hotter than wired charging even though wire charging is nearly 2 times faster

Hello, after sending my s7 edge to warranty for terrible battery (2h Sot at the top after a clean install), i´m questioning if could be the use of wireless charging every night the cause of so fast battery degradation.
In battery health concerned, there is a difference using the wireless charger instead of normal cable charger?
And btw, a good Samsung wireless charger is better than a ordinary one?
I would also like information on this. I have used only wireless charging non samsung charger fast charging disabled in settings. My phone is almost a year old and it out still working well. Just curious about best practice for battery health longevity.

Yes, I'm also have quick charge disabled.
So, what kind of wireless charging? Regular QI, or the newer Fast Wireless chargers? The answer depends on that.
Batteries don't like heat. Batteries heat up when they are charged and discharged because of internal resistance. All those electrons flowing through the battery generate heat. The question is how much is too much.
Rapid charging (like QC 2.0 or 3.0) puts more power into the battery than normal slow charging. More power means more heat. And the closer to full charge the battery is, the more heat is generated. That's why all the rapid charge systems reduce the charging voltage and current as the battery "fills up."
Does wireless charging heat up the battery? For regular "slow" wireless charging, the answer is maybe, maybe not, but probably not enough to notice in any case. There are two things going on with wireless charging. The first is the wireless coils in the charger and phone, the second is the amount of power flowing into the battery. When charging, the coils generate heat. With a well designed phone and charger not a lot, but some. IF the coil gets hot enough, and is close enough to the battery, to heat up the battery, then it could have an effect on battery life. But the output of the wireless coil to the battery is not that great, so the battery won't heat up from the charging itself. Using a standard wireless charger on my Edge, the phone barely gets warm, so I'm not worried about damaging the battery.
With a rapid wireless charger, though, the answer may be different. Samsung's rapid wireless charger puts out enough heat that Samsung put a fan in it. How much of that heat reaches the battery I don't know. But since it's a rapid charger, it's pushing more power into the battery, which WILL make it hotter than a slow charger. So just like a wired rapid charger, it probably does have some impact on battery life
tl;dr version: If you're using a standard (not rapid) wireless charger, don't worry about it. If you're using any kind of rapid charger, only use the rapid charge mode when you really need to.

That's my opinion too.
The fact is that I'm using a regular/slow wireless charger and my S7 Edge barely gets warm at charging. But even so, my battery must have a problem ( I'm waiting for Samsung report). If it proves that wireless charging it's worse for battery (and it's just one year old), I'll switch to the good old usb cable.
You could test it out for yourself with my app

I recommend to read this
:good:
They replaced my battery, now its much better.
For now, I'll try using only the provided charger and cable.
is it safe to leave the device on the wireless charger after 100% charge level? i have the same question for wired fast charging.
wired charging is no problem, since it stops to charge when it's full. even if it shows 100% it's not, because it loses a bit when it's fully charged for a while.
when i use wireless charging over night, my phone is warm or even hot every morning. batteries don't like heat, so i asume it will be damaged after some time.
Do you guys have the same experience with wireless charging? (I'm only using original samsung chargers with my exynos s8)
On my note5 (S8 arrives today). Over night wireless charging did not result in warm phone in morning. Could be because I purposely bought the slow or regular charge cheotech charger

even i have the non-fast charge wireless charger.
I only charge my phone once a day which is when I go to bed, but I turned fast charging off since I don't need it to fast charge overnight. With the previous Samsung wireless charging pad, I'd wake up to a warm phone in the morning (I've just been having problems with the older versions in general). Finally bought the new convertible charger since it was on sale, and I no longer wake up to a warm phone.
I have a none fast charge pad and use it overnight. No warm phone in the morning and battery capacity isn't decreasing very much at all according the Accubattery.
So when I bought my s8+ they bundled in the official Samsung wireless charger, I've only just started to use it, I don't know if it's just me but at times it seems to charge the phone quicker if not as fast as the adaptive fast charger plug. I never thought that would be the case so I'm surprised but happy.
Probably it's just the placebo effect but still, it's nice you think of it that highly.
Can you try to time both methods and share your results? I'm wondering what the actual charging times are.
Charging with cable takes about 1.5h, with wireless charger 2x times more.
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the LG V60 ThinQ can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
Not the absolute fastest around, but damn sure not the slowest... especially when you consider how much further every 1% of battery will take you on this phone compared to other phones in its class. Fast charging kills batteries anyways, so I charge slowly most of the time since I'm always around a plug these days. I really wish I had this phone back in 2011 when I lived on a bicycle and was always on the road away from home and/or power. My only other gripe is that I wish there was a software switch to turn off fast charging like Samsung offered. Sometimes I only have a fast-charge enabled charger around, but would prefer a slow charge.

I don't slow charge in the traditional sense, but I use a QC 3.0 charger for the same reason. It maxes out at 3A to the battery, or 0.6C charge rate. It's still plenty fast, but slow enough relative to battery capacity that it doesn't stress the battery much and no need to worry about turning a setting off in the phone.
Im using 25w adapter PD to charge V60, charging speed is too slow, need above 3hours from 10-100.
Checking battery in hidden menu, saw charong current max is 1,7A, usually lower.
Normal adapter give me same speed (like a cheap samsung fast charge adapter).

I am having the exact same issue. Have you found any solutions yet? I am about to either return the device or change the battery and charge port. Although, I am not sure if it will help because it has 10 watt wireless charging and still maxes out at 6 watts on wireless.

iam using Xiaomi 33w adapter with a Baseus cable, dont use Xiaomi cable (with red color inside usb port, this cable hold 5V only) .
This combo charing my V60 fast (about 1h30 -2h). Its acceptable for me.
Now i dont mind about charing speed anymore.
Hey bro i hqve a 36 watt fast charger. I noticed that my phone charges in 1 hour 40 min before. Now it still ahows me 1 hour 40 min but it takes hours to charge..... It is still showing fast charging. It never happened before
Heres what i have noticed now with 3 phones.
Using my cable charger i notice that charging to 100% then when disconnected and used as an example when it gets to 95% with the phone in screen on it is about 35 to 40 minutes of use.
Using my EFM Qi wireless charger the same as above i achieve about 20 to 25 minutes of use.
I noticed this on the Mate 20Pro, S10+ and now S20U-Exynos
Somehow it seems that cable charging provides longer battery life than wireless charging.
Weird.
