Can I keep my MBP (2019 13") on charge the majority of the time? Is it safe to keep the MBP in a large cupboard?

I have just purchased a USB-C monitor that charges a device whilst transferring video, and I am going to have my MacBook Pro connected to it 24/7 now that working form home has become the norm. I have two questions. I keep my MacBook Pro connected to the monitor all the time, however in the evenings before I go to sleep I turn the monitor off and switch of the mains in which it is connected to. So it is on charge at 100% throughout the day, but in the evenings it is not (and usually drops to around ~70% when I wake up). Is this safe? Also, to save space, I am keeping my MBP connected to an SSD on the top row of my cabinet connected to my desk. The cabinet is open towards the back however is against the wall, and the door is a little bit lower (so someone can open it) so there is air flow. I was just wondering if this could heat up the MacBook by a considerable amount?


Many thanks

The battery and charging system are "smart." They have internal hardware that will not let you overcharge the battery.


I have some concerns about a cabinet, although fewer if it can be vented--one vent low and one high to create circulation. Notebooks tend to run hot anyway due to limited space for fans and air channels. They run eveno hotter when the have to supply data to an external monitor.


The primary action is to make sure the back of the MacBook Pro is not shoved up against a vertical surface, either parts of the cabinet or other items within the cabinet. All the hot air has to exhaust out of the hinge area on the back of the computer. I try to let nothing get within 4 inches (10cm) of the back of my MBP.

Hey, thanks for the response! The MacBook Pro is played horizontally on the first sector of the cabinet, not vertically, although there is nothing surrounding it and the sector which it is placed in is quite wide. I could perhaps purchase a stand or mini fan to allow convection to occur? I would attach an image however it is not allowing me to, but would this still be ok?


Thanks once again!
