    Last week I posted about my [new] phone abruptly shutting down; I noted that it was charging at the time, and the back was hot.

    I'm charging right now and for a few minutes it felt unusually hot again, so I checked its temp:

    Is 98.6°F something to be concerned about? I mean, I know it's ideal for humans, but what about phones? :D

    But, what about those phones whose batteries were starting fires not too long ago? I think that's why I'm a bit concerned. I know those weren't Motorolas, but who's to say it can't happen?

    Were you using a quick charger or a regular one? Charging the battery quickly can make a phone get much warmer.

    batteryuniversity.com has a lot of current (pun intended) info on battery technology that you might find worth reading through:
    https://batteryuniversity.com/learn/article/charging_at_high_and_low_temperatures
    https://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
    https://batteryuniversity.com/learn/article/all_about_chargers

    Regarding all the media hype on smartphones catching on fire, it is important to keep in mind that something like the Samsung Note 7 incident that became its own meme was due to a manufacturing error, and affected a relatively tiny number of phones.

    "TurboPower" as Motorola calls its quick charging.
    But is mine too hot? :thinking:

    If we accept @svim's article as correct (no reason not to) and the upper threshold for Li-Ion batteries is 40°C, then technically you aren't too hot, but you are very close and depending on the ambient temperature, you certainly could exceed 40°.

    You know, I'm starting to wonder if--after all these Motorola years--I might have gotten a lemon.

    First the random lockup/reboot thing, now a temperature issue. It was around 70° in my room today when the battery's temp hit 98.6--and it gets way hotter than that [outside] here in SoCal.

    I'm tired. I don't know what to think. So I'm going to put the phone down and be like Scarlet O'Hara: think about it tomorrow! :)

    Something to always keep in mind is that our phones do heat up a lot, and most people want faster, more capable phones that in turn require better CPUs and GPUs that result in generating more heat. There's no ventilation fans, like in a desktop or even laptop, and typically little to no openings for any heat to escape out of, even less so for waterproofed models. Plus there's very, very little open spaces inside with tolerances between everything being very tight so it's basically just conduction for all that heat to slowly leak away. Add a phone case, most not being made of some kind of metal that will transfer heat better but rather plastic or rubberized synthetic that insulates rather than conducts, and that adds to the problem.

    A lot of this pertains more to our phones in actual use though, it is puzzling that your phone is heating up like that when it's idle. Assuming this wasn't always happening and just recently became an issue, if you go into your Settings >> Battery menu is there anything showing that looks odd?

    Honestly it could just be a lemon, if any matter of the phone, it could be just need to cool down first and relax for a bit too. I know I had the same phone she has for around three years, it never got to the point of where it got too hot..


    Also check em running bg apps too.

    Very good points. Thank you.

    Two important differences between my old [which I'm still using] and new phones: old is in an Otterbox Defender Case--so if it ever got hot, I didn't feel it; new has 'turbo' (quick) charging.
    No--it's been in use both times. If you look at my 'phone abruptly shut down' thread, you'll see that I was using its camera for the first time when it happened.
    "Always" and "recently" are the same! It's brand new. :) I've gone through its battery settings and haven't seen anything peculiar.

    Thanks a lot for your informative and thoughtful comments. They're appreciated!

    Hmmm...
    Put it in a cooled down room for a while,
    Settings > Display > Sleep > 15 seconds.

    Disable it and check if it get hot
    2. check the IC if is getting hot
