I didn't notice a discrepancy with my S9+ but it takes a lot longer to charge on the Samsung and Anker wireless stand. I noticed it one night when after being on the Anker charger for over 3 hours it had not fully charged. It was probably ~15% when I put it on. I swapped out to the Samsung OEM fast charging stand the next night and still the same issue. When I plug it in the estimated charging time appears to be cut by ~50%.
Also, I'm only getting a day out of a full battery. Granted I use the hotspot a lot. Should it be better? Snapdragon processor.
"Fast wireless charging" was removed from settings. Possibly for safety reasons. Hotspot generally uses a lot of juice. My Moto E can last long periods in hotspot mode, not sure how the s10 measures up.

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

:good:
They replaced my battery, now its much better.
For now, I'll try using only the provided charger and cable.
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
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.
Sometimes I notice when I charge, it will start off in "Turbopower Connected" mode, but if I pick it up later, it will be in boring old slow charging mode. Typically, I can fix this by unplugging and plugging in again, and then it finishes up in Turbopower / Quick Charge mode.
This happens on both the real charger I have, and also on these ones I bought from Aliexpress. (They're super great, by the way. Replacement chargers for $2.98? Awesome). My cables are a mix of real Moto ones and standard cables from Monoprice.
Just curious. Not a huge dealbraker, but once you get addicted to quick charging, you get disappointed when it says "1 hour remaining".
Snapdragon devices have intelligent charging which allows them to charge faster when the battery level is lower. Up to about 76% they charge very rapidly, then gradually back off the higher percent it is charged. This is designed to save the life of the battery.
No issues since june 2017, and I've been using both Motorola Turbo charger and an Asus Quickcharger. There's no significant charging time difference between the two.
There are so many options.
Superfast charging I find amazing. Quick plugin and the phone is back up to about 80% battery in no time at all.
Fast is ok. Just a little slower.
Standard is slow, it just ticks over.
I also notice that it appears to stop charging when the battery is full. Although I've stopped leaving my phone plugged in overnight.
But, I read that superfast might damage the battery and that's why it defaults to off. It's not a quick switch to enable/disable, so it's a decision to have fast or superfast on.
Or is life too short to worry?

Even if super charging would make the battery loose efficiency over time, I don't think it will be a noticeable problem during first owners time with the phone. I will upgrade in less than 18 months and I think most ppl upgrade within 2 years.

Fast wireless charger most of the time, but I did buy a couple super fast wired chargers to scatter around when I'm in a time crunch

Super Fast wireless charging all day everyday. I haven't plugged a cable into a phone since 2018. Battery life is solid so I'm never in a rush to charge a phone. Wireless is quick enough. I love the convenience of just throwing it in the stand without having to find the cable and stick it into the port. Especially in a dark room.
I've not really used wireless charging. So you have 15w wireless pads around the house?
Super fast charge too.
With PPS and the PD standard, it changes its power according to of the actual battery level and temp (and certainly more parameters) to avoid harming it.
I plug in every night, overnight next to my bed. Not fast charging, just regular charge, because it's not needed.
If you don't need to fast charge every day, turn it off. Doing it regularly will degrade long term battery life by a small amount. Both by the method of charging, and by the heat created by fast charging, as heat is bad for the life of a battery.
But all in all, it's not terrible. Just charge it howver you want. It's not going to cause any terminal issues. Just charge it when and however you want to.
I have switched off both Superfast as well as fast charging. Not sure if that will have any impact positive or negative as my opinion is that Samsung didnt go with 40W, 60W so on and so forth charging not because it cant do it (If Oppo,Vivo, Xiaomi can then Samsung definitely can) but as a bigger company they probably wanted to act more responsibly so they must have ensured that their 25W charging has negligible effect on battery and thats why they went with it. Just my 2 cents.
