Is wireless charging good for your battery?

The thing causes my S8 to heat up, even when I turn off the fast option, more so than fast wired charging. Is it really good for my battery health when the phone is heating up for the entire two or three hours on the charger?

The phone will stop charging automatically if it thinks the temperature is not comfortable.
Do not stress over things that are mentioned in the manual, inductive charging will generate more heat than a wire, but the phone is more than capable of managing the process and stopping if things get too hot.

And no, the temperature isn't going to get high enough to damage your battery. (Unless you are using unauthorized wireless chargers / fakes that can cause the actual metal casing to heat up, google this).

I too had this question back when I bought my Wireless Charger for my S7. Interesting to get more feedback from the others. E.g. Does it shorten the battery life quicker considering it heats up the battery more than on cable.

I've wireless charged my s7 since I got it and also wireless charge my s8. I've also added wireless charging to an LG G3 and G4. IMO it does not degrade the battery and fast. The way I look at it, it saves the charging port from 100's maybe 1000's of plugs/unplugs. It's also a point of device failure, so from that perspective, it's better. Again, IMHO.

How about if you introduce the extra variable of putting the thin metal thingies for magnetic car mounts between the phone and the case? Does that change the situation?

Another variable is a case, which can add to heat build-up. Overall, I have seen nothing definitive that suggests that heat won't adversely effect battery life. Notwithstanding the money companies make selling QI chargers.

The fan in the authentic Samsung Desktop charger only activates if fast wireless charging is turned on in the phone.
The fan is to cool the phone.

I use the Samsung desktop stand but usually just normal charge it to which apart from typical heat being discharged I've not experienced any other issue.
I do not use a case.

There is opinion that constantly using Fast Charging can reduce the batteries condition over time. Wether you believe this is personal opinion. I've only Fast charged maybe 2-3 times if I've needed a quick boost of juice.
