I have one Belkin 7.5W wireless charger at my desktop computer and one on my nightstand. Phone goes on the wireless charger on the nightstand at night and is 100% in the morning. If I need a top-up charge during the day, I'll drop it on my desktop charger if I'm at my desk, or plug it into whatever charger is available if I'm out and about.

So I have tested it, with 12W power from the wall was not over 5,8W. Charging times with 5W and 12W are almost the same for iPhone 6S.
iPhone 6S Plus takes advantage of 12W charger.
Interesting. I don't have a 6S but I'm gonna check if behavior's any different on the 4.7" iPhone 7. It was just charged overnight so need to drain it first. It's possible the faster charging is only available on the Plus phones since they have bigger batteries.

I've always just charged with a 12W port for convenience (so it works for both iPhone and iPad).

Edit:
Yep, iPhone 7 (4.7") supports up to 12W charging.

Isn’t the iPhone getting hot when you charge it with 61W?
No the phone can regulate how much wattage it takes. Once it reaches the maximum wattage it can support it won’t take anymore. So it will stop at 18 W even if the charger is capable of outputting note.

Just got a new wireless charging stand and it has taken wireless charging to new heights!!!

I can now watch videos and charge at the same time without worrying about the phone going dead. Yes!!!

I picked the two I use the most. I have a wireless Qi charger on my nightstand that I use when I need to charge overnight, when speed doesn't matter. At my desk I charge with an Anker powerstrip "puck" that has two 2.1A (12W) USB ports. Usually when I charge at my desk I need to charge pretty fast, so I charge wired there.

In my travel bag I keep the 18W charger that came with my 11 Pro Max, since when traveling is when I most might need to really charge the phone fast. I've hardly used this charger since I got the phone, but I did use it once on a trip when I forgot to plug in overnight, woke up with it at 6% and was thankfully able to get it up to 60% or so really quickly with that charger!

I always use the charger built into the phone. It’s the only charger anyone CAN use. But I use various power adapters (transformers/rectifiers). 5 watt, 10 watt, 18 watt, 30 watt plugins and a 7.5 watt wireless.

I use either a dock thingy which has 3 USB ports, a wireless 9w Samsung charger I got for the note 8 or the included 18w usb c charger that came with my iPhone 11 Pro

Because why not.. I charge this way exclusively and I LOVE IT!!!

Seriously, why would one use anything else!? The convenience is unreal. Tbh you're doing it wrong if you aren't wirelessly charging... Like frfr
Yeah I don’t carry a wireless pad with me to work ... haven’t had the need to charge it at work or out since it lasts forever but as much as I like it and do it at home I tend to wireless charge my AirPods pro and not my phone

All iPhones gets hot from the new charger. The slower you charge a battery the cooler it stays and the longer it lasts. I also keep it between 40 -80%.
I am never in need of getting my phone charged fast.
Errr mine doesn’t...

Good old 5W that came with my Xs. Faster charging isn't really something that I need since with my usage, the battery lasts for 2 days and I can charge my phone during the night at the end of the second day. Optimized charging enabled of course.

I have two iPhones I use daily. An iPhone Xʀ and an iPhone 5c. My 5c is my “security” phone. (Third world country, you know the drill).
I use the 5w charger exclusively for both. I generally charge my 5c overnight and the Xʀ is charged a little more haphazardly.

iPhone X here. At night I use an Anker powerwave charger on the night stand. At work i use a 30 watt usb c charger and in the car is an Anker powerdrive PD charger. I know its not healthy to fast charge all the time but i use my phone a lot and am trying to keep it charged when i have the chance. Plus I’ve put 700 cycles on the phone in a little under a year and its still at 96 percent health.

And is there no difference for the battery, wheater it's charging with 5W or 18W?

Lower powered chargers charge the battery with less current. Less current = less heat. Heat created from fast charging (iPad charger & up) becomes significant in the summer when ambient temperature is high. When the air is cool, it doesn't matter, battery won't get too hot.
Using a fast charger on a hot summer day (or warm day) will definitely heat up the battery beyond ideal.

Does the iPhone even throttle charging based on phone temperature? I know my Samsung GS8+ did because one day I had the charging rate app running, and once I got in my hot car, I noticed the rate plummeted. Once I ran the air and held the phone to the vent, it went back to normal. I know the iPhone definitely throttles brightness in heat, which is definitely annoying, since daylight is the one time I need high brightness.

Yes it definitely does, it's easy to see if you've got a Battery app that shows charging current, but the bigger chargers will still heat up the battery a lot more than the little 5 watt charger
