Because the older Intel MacBooks consumed way more power, they had to fall back onto the battery reserve more often when the power brick could not supply enough. Instead, the computer is completely powered by the power supply and the battery is left alone. When the charge limit is at 80%, your MacBook does not trickle charge. Regarding the second reason: Even when your laptop is powered by the power adapter and the battery is not being charged, sometimes the hardware needs more juice than provided by the adapter, in which case it taps into the battery and discharges it a little bit.įor any reason, this can take a long time (mostly dependent on the size of your power brick) and you should not expect to see a quick battery drop beneath your limit while in sailing mode, as this would hurt the battery more than it helps. This can happen because of two reasons: Batteries do discharge themselves slowly over time because of the cell chemistry, even if there is nothing they are powering. Instead, it waits until your battery drops a few percentage points by itself. Sailing mode does not actively discharge (eg unplug) your MacBook. Maybe as the battery gets older, I'll start to see the battery percentage drop from 80% - as the older battery won't hold its charge as well any more (which was one of his two reasons for the 80% level dropping, cell chemistry). His two reasons don't apply - the newer battery in an M1 Mac isn't discharging much because of cell chemistry, and there are few if any times that the M1 Mac has to draw power from both the power adapter and the battery. On an M1 Mac, the battery (at least when it's newer) will hold that 80% charge most/all of the time (as the two reasons he gives for why the percentage would drop won't happen much on a newer M1 Mac), which is why I don't see the percentage drop from 80% to 70%. I think what he is saying is the MagSafe charger powers the Mac even when the battery is at 80%, and AlDente keeps the battery charge from going above 80%. I should have known that was wrong as the LED is "orange" which means "charging" (and connected of course). I think my misunderstanding was that I thought the battery powers the Mac once the battery is at 80% and that the power adapter does not supply power until the battery drops to 70%, at which time AlDente lets the power adapter charge until the battery is back up to 80%. Your Macbook will start charging until it reaches 90%.I heard back, I pasted what he said below. You switch to User B on which the Charge Limit is set at 70% with AlDente. You are using User A and your MacBook’s current battery percentage is 70% and it is charging to the set charge limit of 80%. Your Macbook will start charging until it reaches 90%. You switch to User B on which the Charge Limit is set at 90% with AlDente. You are using User A and charging is paused at 80% with the Charge Limiter feature of AlDente. AlDente will continue to pause charging and your MacBook will stay at 80%. You switch to User B on which the Charge Limit is set at 80% too with AlDente. What happens if AlDente is not installed on the other user account?Īs soon as you switch from the user account which has AlDente installed and charging is paused, your MacBook will start charging to 100%. However, you can always only use the feature of the current version activated on the current user account. This means, that you do not need to have only AlDente Pro or only AlDente Free on all user accounts in order for Fast User Switching to be supported. What about AlDente Pro and AlDente Free?įast User Switching support is included in AlDente Pro and AlDente Free and it is even interchangeable. Furthermore, after switching users, it might take a minute or two for everything to work as intended. Pause charging with the Charge Limiter and bring the battery down with Discharge and so on. Here is how it works: Just install AlDente on every user account you want to use it on and use it as you normally would. However, you need to follow a couple of steps to get it to work properly. It is activated by default and you do not need to change any setting in AlDente. Since version 1.15 AlDente supports Apple’s Fast User Switching.
