MacBook Pro charging issue

[macman4789]

Hi,

I recently got a 15inch 2018 MBP and I’ve noticed that whenever I plug it in to charge overnight, that when I wake in the morning the bottom of the MBP is warm and so is the charger. It’s not really really hot, but I’m aware that once the laptops reach 100% charge that they are meant to ‘trickle charge’ instead of pumping the full current all night.

When comparing to my 2015 MBP which has MagSafe 2, the bottom of the laptop and the charger is completely cool after charging overnight and wondered whether this was normal for 2018 USB C charging?

Apple have ran a load of ‘diagnostic tests’ and said that it passed all of them... if it’s normal then fine but with it being electricity related wanted to know if it was unsafe.

Thanks

That appears to be normal behavior for those models. No worries.

I see, thanks for your reply. It seems strange that my 2015 MBP is cool upon unplugging in the morning and the 2018 one isn’t. I just started thinking there was something wrong with the power management and it was over powering it all night.
