Lithium-ion cells degrade fastest at high states of charge. Keeping your MacBook between 20–80% can nearly double its useful lifespan. The fix? A simple alert when you hit 80%.
Alerts for every battery moment
Get notified the moment your MacBook crosses 80%. Unplug, let your battery cycle lower, and extend its lifespan by hundreds of charge cycles.
A subtle notification when your charger is plugged in — confirmation that your Mac is actually charging. Perfect for flaky USB-C cables.
Instant alert when your charger disconnects. No more finding out three hours later that your kitten yanked the cable.
Assign a different macOS sound to each lifecycle event — one for plug-in, another for unplug, another for hitting 80%. Silent mode also supported.
Combines with Juicy's custom alerts to give you the full lifecycle picture: charging up, hitting 80%, unplugging, draining, and reaching critical levels.
Backed by lithium-ion chemistry research — keeping your battery between 20–80% significantly extends its rated cycle count and overall lifespan.

Everything about protecting your MacBook battery with lifecycle alerts.
Lithium-ion batteries degrade fastest at high states of charge. Keeping your MacBook between 20–80% can dramatically extend its lifespan. An 80% alert lets you unplug at the sweet spot before damage accrues — without needing to remember manually.
macOS has 'Optimized Battery Charging' which delays charging past 80% based on your schedule, but it only works predictably if your usage patterns are very consistent. Juicy's explicit 80% alert works every single time, regardless of your schedule.
Yes. Juicy sends an instant notification the moment your charger disconnects — so you'll never discover hours later that your cable was loose or knocked out.
Absolutely. You can assign a different sound to plug-in, unplug, charged-above-80%, and low battery alerts. Or go silent and use only the on-screen notification.
Yes, indirectly. The alerts remind you to unplug near 80% so lithium-ion cells don't sit at high voltage for extended periods — which is one of the main causes of battery degradation. It's a simple habit that pays off over years of use.
Yes — they're designed to work together. Lifecycle alerts cover charging events and state changes, while custom battery alerts cover specific percentage thresholds. Most users enable both.
