    Just received my Note 8 on Tuesday!

    I've read that heat is one of the biggest enemies of your phone's battery.

    One thing I've noticed when using Samsung wireless charging is that the phone stays warm even after being fully charged. When charging with a wire / cable, I notice that the phone immediately starts to cool off after the charge reaches 100%.

    What is the general consensus on this issue? I like the general concept of wireless charging... it's easy to set phone on the stand while sitting at your desk, but I find that even Samsung's Fast Wireless Charging is much slower than using a wire.

    I'm not sure that it's even worth using this feature.

    Are you using the new wireless charger or the older one? I don't know if that would make a difference

    I could have sworn I replied to this thread. must have forgotten to click on post reply again...

    I never really had a problem with my wireless charging. never noticed any head difference between wire and wireless charging. I guess there could be issues depending on the quality of the wire/wireless equipment. I never read of any issues in any of the tech sites I regularly visit.

    I have been using wireless for years without any issues, well, with the exception of that one time right after the nougat update. there are times the phone is warmer than normal but it has happened with both wire and wireless charging. as far as the phone cooling down faster after a wire charge - never noticed a difference.

    if you do a forum search, there was a thread a couple weeks ago about the same thing.

    Thanks! Yeah, trying leaving your phone on the wireless charger for a bit after it reaches 100% charge... it's still generating quite a bit of heat. Then try the same with a wired charger... the phone will be much cooler only a few minutes after reaching 100%.

    I figured this out because I charge overnight on my bedside table. When I wake up in the morning, my phone is hot if it's been sitting on the wireless stand, but it's room temperature if I'm using the wire.

    It's almost like the charging doesn't shut off when using wireless.

    I've noticed this on my S7 and now on the Note 8.

    You did. There are two posts asking the same question, the first one (and you did reply there) is located here:

    I use wireless on my S7. If it's not reached 100% & then I pick it up to use it, it feels warm, but not dangerously hot. First thing in the morning with 100% charge, mine is normal room temperature. When my N8 comes in, I'll keep an eye on it. And, I don't use Samsung wireless chargers either.
