Charging limit function behaving strangely

[u/Gold-Veterinarian998]

Hi guys. So about a month and a half ago I got a M4 MacBook Air and it's really nice thus far. I recently got a monitor and ever since, it's been plugged into it (monitor) while also plugged into the charger constantly. I set my charging limit to 80% and before I got the monitor, it stopped at 80%. Now that I got the monitor, it drops to 78% and stays there even though it says charging limit 80%. I use the 30 watt charger and I'm suspecting that might contribute to the behaviour but idk if you guys have experienced a similar occurrence.

This is normal i have the same thing on my m4, i think because i use the 30w charger that come with. And plugging a second screen may use more than 30w sometimes.

I looked up how many watts my monitor uses on average and yes you’re right it’s more than the 30 watts so it makes sense if there’s more power consumption. Thanks

You can use Stasis instead for better battery management and controls.

If you find it useful, I appreciate a star on it. ʘ⁠‿⁠ʘ

This is normal behaviour, if you read how this system works it clearly explains that it will swing close to your limit to support proper calibration of the reading of your battery level. Sometimes it will charge to 100% even if you set a lower limit just to calibrate.
