    I noticed this morning that my watch was warm from recharging. It had been connected to the charging cable all night. My iPhone is always cool in the morning as it seems to stop putting power in after it reaches 100%. Is anybody else noticing this?

    Inductive charging is generally warmer than what you'll see from your lightning cable

    Thank you for responding. I'm not sure how the charging works when the watch is full, but I suppose if its trickle charging or letting it drop and topping up, this could explain it.

    You don't say? I suspect everyone should notice this. Moving electricity generates heat.

    I realize this. The point being it probably reached 100% charge 6 hours earlier while I slept, so I was somewhat surprised that the watch was still warm in the morning.

    Hopefully the watch is smart enough to know its at max charge and limit the current going to the battery after that... the fact thats its so warm hours after it reached max charge tells me it might not be doing that.

    My watch was hot and had turned off or froze. I had to hard reboot it and let it sit for 15 minutes to cool down to touch it consistently. 1st night if it does it again im calling apple.

    My SG did this and was actually not charging anymore so the battery got discharged as it sat there with the charger on.
    But I haven't seen this on my silver or my wife's.

    I'm interested to see how mine goes tonight. I'm sure it's designed to limit the charge after its close to full. My concern was that it might not have been doing so.

    Mine is 42mm SS by the way.

    Lit-ion batteries MUST be smart enough since they will gorge themselves until they explode and catch fire.:D

    Inductive charging (wireless) is less efficient than wired and waste more energy emitted as heat.

    My wife's 38mm modern buckle watch is warm, however my 42mm Milanese is not. Also, hers does not charge to 100%. I'm concerned there is something wrong with her watch.

    I've noticed that mine is usually warm when I take it off the charger in the mornings .

    Everything that Apple makes with a battery is known to run / charge warm to hot. Cool temps are not one of Apples priorities.

    I understand that, but it shouldn't still be charging after all night. My watch is cold when I pick it off the stand, however, my wife's watch is at 98% and warm. Something tells me something is either messed up in software, or the charging circuit is messed up on her watch. I'm sure what to do honestly.

    If evidence leads you believe there's a problem, contact Apple.

    You're still within your 90 days of complimentary phone support, so perhaps start there.

    I did a hard reset. Was at 92%. We are going to go out today. I'll probably call on Tuesday since its Memorial Day weekend. See what they say.

    Drain her watch to zero then recharge. The software battery meter is just an approximation; draining and re hanging will reset/recalibrate.

    There's otherwise nothing wrong with a warm watch after charging.

    There surely is if it won't charge to 100%? - especially being brand new and all.

    My watch is warm too sometimes. But not every morning.
    If the Watch is warm i do a restart.

    Did you drain to zero and recalibrate? This isn't specific to the watch. Happens with phones, laptops, iPads.... Anything with a battery and a software charge meter.

    Unnecessary.

    Check that alignment of charger puck and watch is perfect, too.

    Misalignment of inductive charging components results in inefficiency, which = heat.

    How can you drain to 0? By that time I'll be in power reserve for two days LOL! I did a hard reset. And that seems like it may have fixed it. I'll keep an eye on it. Her battery seems to be lasting. She's at 88% right now.
