Does the battery fail when the m4 macbook air + 30W charger is connected to the power supply?

Have you encountered the same problem: when fully charged, the battery often drops to 99 98 or even less when using the magnetic charging cable, and then the purpose of protecting the battery will not charge the battery immediately, resulting in frequent orange light. The guess may be as follows: -30W power is too small, and the battery will be consumed under overload -Charging cable contact problem -macos new [battery health] strategy? Supplement: The same 30W charging head, I haven't noticed this problem for the time being when using the c2c cable. Maybe it's because the light is not on, so I didn't notice the battery that quietly powered down

m3 air will lose power when connected to an external monitor

@ Anonymous8415 Which monitor do you connect externally? Generally speaking, the minimum is 65W, right? Can this lose power?

I remember that the charging head provided with MacBook Air should be 30W... I feel like this shouldn't look like this

@ Poster Some monitors even only have 9V @ Anonymous5606 18W ones. It can only be used to connect to a Mac, and it can't be charged when connected to some Windows notebooks that only support 20V.

@ Anonymous8464 Yes, I doubted it briefly, but I felt that it really shouldn't be. At present, further investigation shows that there is no such problem when charging with the typec port, but the magnetic suction port obviously has this problem. I don't know if it is a wire or interface problem.

@ Poster The charger should be included in the "limited warranty". You can take time to go to the store to see if it can be replaced

Generally, it is a battery strategy. You can try to turn off the optimized battery power supply in the battery strategy, and it should not lose power

@ Poster # 2 35w double-headed. There is usually an opening for charging the iPhone Monitor 32-inch Titan

@ Anonymous8415 The dual-headed 35W dual charging seems to shunt part of the power, and the single port is estimated to be less than 35

@ Anonymous3124 It's true that as you said, I'm more messy. What kind of apple is this singing?
