My Macbook Pro 13- inch, 2020's battery health is normal, but when I charge it, the most I can get is 80%, then it's just stop.
MacBook Pro 13″, macOS 15.4
thanks all for helping!
I have updated my system to the newest and the problem is solved.
The macOS version your MBP is running - 15.4 Sequoia - does not have the 'Charge to Full Now' option. Maybe it was introduced in Tahoe?
Regardless, you should consider updating your OS to the latest Sequoia version 15.7.2 at least.
And here is some of Apple's guidance on the subject.

Good computing Helennnn7 ! Appreciate the update on your resolve.
There's no "charge to full now" even when I plugged in the charger. I have taken a few pictures in system settings. I didn't know much about how macbook battery functions since I only use it for research and school work. So is there anything wrong with my macbook? the problem has appeared for three days.
Do I need to take it to repair? (thanks sm for replying)

Battery Health Management...(?)

old issue new issue, what changed?
Do you have the option—>Charge to full now
The rule of thumb—if you are near the mains leave it plugged in, if you need the portability then run on the battery only—this is how you help optimize your battery charging and extend the working life of your battery by reducing the cycle count.
— even BHM does not lock in @ 80% BHM is dynamic it is not absolute..
—BHM learns as it goes, and will make appropriate changes for long term battery health.
—you still have an expected 1000 cycle count
Maybe you can say more about your situation...
Your Mac appears to be working as designed.
Battery Health Management feature tracks your usage history and detects that you do not generally run your battery down to low levels. So when you see less than 100 percent as a full charge, it is charging less than the highest level for longest battery lifetime.
NOTE that charging to 80 percent is a side-effect, NOT the GOAL.
The goal is to have some hurly-burly (percolating activity) around using your battery, either by your actually using it, or by leaving it less than fully charged, so that the cells are not 100 percent charged 100 percent of the time. Battery Health Management will also from time-to-time let the battery decline slightly to 'get some exercise' and run lower (thought to be around twice monthly) if you do not do so by your ordinary use.
The feature tracks you actual usage. If you continue to not require 100 percent charge for a few weeks, it generally will revert to a lower "full" level. but it takes some experience, which takes some time
If your recent usage patterns demand top battery capacity, the battery will charge completely to be sure you are not stuck out in the wild with no power.
Executive summary: “If you keep your Mac plugged in continuously for several days, it will start pausing the charge at 80%. If you run a small amount of the time on battery, it will keep doing that. If you run some of the time on battery, it will charge to 100%.” © 2025 neuroanatomist
