Hello, I bought a base model 2022 13" Macbook Air in August 2023. It’s been 3 months and there has been zero problem till now. But, today my laptop shut down at 20% and wouldn’t start till connected to a power source. I charged it till 25% and unplugged it. I waited until it got to 20%, and it shut down again, and the exact same scenario happened. Can anyone help me with this?
I use AlDente regularly and use my laptop with an external monitor.
It’s because of aldente. You need to re calibrate
thank you!
My guess is that AlDente caused this. Have you been following the “IMPORTANT” directions in the documentation?
IMPORTANT: Keeping your battery at a lower percentage, such as under 80%, over weeks without doing full cycles (100%-0%) can result in a disturbed battery calibration. When this happens, your Macbook might turn off with 40-50% left or your battery capacity will drop significantly. However, this is only due to a disturbed battery calibration and not because of a faulty or degraded battery. To avoid this issue, we recommend doing at least one full cycle (0%-100%) every two weeks. Even if your battery calibration gets disturbed, doing 4+ full cycles will recalibrate your battery and the capacity will go up again.
so i should charge my battery to 100% and let it go to 0%?
According to the directions, doing that a few times is supposed to fix the issue.
(This is why I don’t use AlDente, by the way. I don’t want to be inconvenienced by stuff like this and I haven’t seen any strong evidence that it actually helps with battery health vs. the stuff built into macOS.)
i tend to use my laptop with an external monitor. if i use it unplugged, it drains battery faster than usual, which will end up in me doing more battery cycles. on the other hand, if i keep it plugged, it will stay on 100% for a long time.
do you think this will have any long term battery effects?
Yup, I use my laptop ~90% of the time with an external monitor. The macOS “optimized battery charging” feature does a perfectly fine job of keeping my battery at 80% charge.
I know it doesn’t work for everyone, but it works fine for me and I don’t have to worry about the issues that AlDente can cause if you avoid the “IMPORTANT” maintenance step.
This is a issue. I would contact whoever you purchased it from and talk about a return or repair. Especially if you got it directly from apple.
thank you!
