Travel Mode.Full charge for the trip. Back to your cap after.
Sensei normally holds your charge at the cap you set (80% suggested) so the battery ages slower. The night before a flight, tap Travel Mode. Sensei lifts the cap, charges to 100%, switches to stricter low-battery warnings (30% / 15% / 5%), and pauses Apple's Optimized Battery Charging. The next morning at 9 AM your normal limit comes back automatically. No reminder to undo it. No battery sitting at 100% for weeks.
Why it matters
Lithium-ion batteries age faster when held at 100%. A typical "top up before a trip and forget" leaves a MacBook at full charge for weeks, measurably aging the cells. The 9 AM auto-reset is the safety net: even if you forget, the cap returns.
How Travel Mode composes with macOS
Apple’s own charge-protection features — Optimized Battery Charging and Charge Limit (macOS Sequoia 15+) — work well for predictable routines. They fall apart in one place: the day before a trip. The ML in OBC has no way to know you’re flying tomorrow, and a manual Charge Limit set to 80% will stop charging right where you need a full battery most.
Travel Mode is the bridge. One tap and Sensei:
- Lifts your charge cap to 100% for the trip window.
- Pauses macOS Optimized Battery Charging so it doesn’t fight you.
- Switches the low-battery thresholds to the stricter Travel preset — 30 / 15 / 5%, instead of the everyday preset that may not warn until 10 or 5%.
- Schedules an automatic restore for 9 AM the next morning, local time. Your normal cap returns, OBC unpauses, and the everyday alert preset comes back.
Why the 9 AM auto-reset, not "detect arrival"
A common feature request: “restore the cap when I get home.” It sounds simpler, but detecting “home” reliably means watching Wi-Fi networks, location, or charger identifiers — all of which fail in the obvious cases (hotel Wi-Fi the same SSID as home, a coffee-shop layover, a different charger on the trip). The 9 AM reset is dumber, more predictable, and impossible to spoof: even if you forget, the cap restores itself the next morning. If you stay away longer, you re-tap Travel Mode each evening — the friction is exactly the right amount.
What the stricter alerts look like
The Travel preset fires earlier and louder than your everyday config:
- 30% — Info card, 6-second dismiss. The first nudge. Enough runtime to find a power outlet without rushing.
- 15% — Warning, 12-second dismiss. By now your seat neighbor’s charger is the next move.
- 5% — Alert, persistent until acknowledged. The plane will land before this matters, but Sensei makes sure you notice.
The trade-off is one extra notification on a normal day. The reverse trade — silence until 10% on a plane — is a much worse deal. If you want a different cadence (say, 35 / 20 / 8), the custom thresholds feature lets you build it.
A note on heat
Travel Mode lifts the cap; it doesn’t change the cell chemistry. The day you charged to 100% and immediately drove the laptop in a hot car to the airport is the worst-case combination for thermal stress on lithium-ion. If you can charge to 100% the morning of the trip rather than the night before, do — every hour spent at 100% in a hot bag is an hour of accelerated chemical aging.

Frequently asked.
- Will Travel Mode override Apple's Optimized Battery Charging?
- Yes. While Travel Mode is active, Sensei pauses OBC for the trip window so it doesn't second-guess your need for a full charge. The 9 AM auto-reset re-enables OBC alongside restoring your normal cap.
- What if my flight is later in the day?
- Travel Mode keeps the cap lifted until 9 AM local time the morning after you enable it. If your flight is at noon, you can re-enable Travel Mode in the morning to keep the cap raised through the trip — or just leave the 80% cap and rely on stricter alerts plus the partial charge.
- Does Travel Mode work without an internet connection?
- Yes. Sensei is fully on-device — no network is needed to lift the cap, fire the stricter alerts, or auto-reset. The 9 AM reset uses your Mac’s local clock, not a server.
- Can I extend Travel Mode for a multi-day trip?
- Re-tap Travel Mode each evening before sleep — the cap stays at 100% through the next morning. Most travelers prefer this rhythm over a multi-day mode because it forces a daily check-in: “am I still on the trip?”
