Your notebook’s battery has a hard job. It has to supply the whole system with precious energy while you are on the go and sit still and retain all that power juice when you are plugged in at your desk. Even more, it also must help out the power supply when your system demands more than it can deliver. With all these important tasks, it is not surprising that batteries can sometimes forget how high (or how low) they can actually go. This phenomenon is called “Battery Miscalibration” and occurs when the battery management system is out of sync with the battery. For most people, this manifests in their notebooks turning off at 60% or even higher percentages and other unusual charging behavior. If you keep your battery at lower percentages for a longer time with no or little charging/discharging, this is very likely to happen at some point.
If you experience such symptoms, attempting to recalibrate your battery is usually a good idea. This procedure involves letting you battery drain to 0% (or as close as you can get), charging it back up to 100% and waiting an hour or two before you start to discharge your device again. If the battery management system is significantly disturbed, it can also help to do this procedure more than one time.
Even if you are not currently suffering from battery miscalibration, but you keep your device plugged in at lower percentages over an extended amount of time to avoid battery degradation, recalibrating your battery twice a month can prevent battery miscalibration from happening.
AlDente Pro allows you to recalibrate your battery with the press of a button. You can activate this feature in Settings → Charge Settings → Calibration mode. Once activated, AlDente Pro will discharge your battery to 15% (even when you have your MacBook plugged in), charge back up to 100% and stay there for an hour bevor it starts discharging again to your desired charging percentage.
