They should just make 50% the new 100% and then let you "supercharge" to 150% when you need to. I'm kind of surprised Apple hasn't done this already.

Nitpick: if 50% was the new 100% then the supercharge option would be to 200%, which sounds even better :)

I've noticed that on newer (past few years) MacBook Pros, if their battery runs down too far they refuse to start up, even when plugged into the charger. The battery has to charge for 10-15 minutes with the "dead battery" icon on the screen. It's exactly the same behavior as iPhone/iPad. In past MacBook models, the battery could be dead--or even completely removed--and the charger would power the laptop fine.

Anyone know why this extremely irritating change had to be made?

Hey Apple, this is the perfect opportunity to take advantage of the clean USB-C ports arrangement on new MacBooks! Charging Mode 1) By plugging the charger into the rearmost port, full 100% fast charge please. Charging Mode 2) By plugging the charger into the other, nearer port, I’m indicating that we’ll be here for a while... please trickle my battery up to 50-75% to prolong the battery’s lifespan. Indicate which mo…

This is a terrible idea. Even if you're going to do this it's far better to be a toggle on software rather than tying it to the port you're using.

But you can see what state the laptop’s in from across the room.

I didn't think the USB-C / Thunderbolt port situation could get any more complicated and confusing [1], but congratulations, this would certainly do it.

My guess is they want to be able to perform clean shutdown if charger is removed.

Just let me set a max charging percentage like on my Thinkpad please.... After 2 years the battery on my MacBook Pro is pretty much dead.

You should probably check your battery cycle count: https://support.apple.com/en-us/HT201585

I can't even glance at a MacBook on my desk and tell if I plugged into the closer or further USB-C port

Another nit: Maybe we never let the user get to 200% by refusing to charge beyond 150% (internally known as 75%?) ever.

Better yet, all devices, phones, tablets, notebook computers, headphones, speakers, ... should automatically stop charging at about 75% and then continue to run directly off of the wall. I used to think that's what all devices do because that just seems like common sense to me.
