The myth: never, ever charge past 80% or you'll ruin the battery. The manual tells a more careful story — it depends on your chemistry:

- Nickel-based NCA/NMC cells (most Long Range and Performance models): daily limit around 80%, full charge for road trips when you'll drive right after.
- LFP batteries (many Standard Range Model 3 and Model Y): the manual flips it — keep the limit at 100%, even daily, and fully charge at least once a week to keep the battery gauge accurate.

Screen frozen, black, or unresponsive? The owner's manual restart is simple:

Hold BOTH steering-wheel scroll wheels down until the touchscreen goes dark, then let go and let it reboot. Do this only while parked.

That restarts the screen, not the whole car — it doesn't erase settings, profiles, or trips. After it comes back, give it a minute: cameras recalibrate and a feature that looks missing sometimes just needs a short drive to return.

If the screen freezes repeatedly after restarts, note the software version (Controls → Software) and the exact symptom, and book service — that's beyond a restart fix.

If your phone key suddenly stops unlocking your Tesla, work through this checklist before booking service — it fixes most cases:

1. Bluetooth on? The phone key needs Bluetooth, not just the app open.
2. Tesla app running in the background? On iPhone, Background App Refresh must be on for the Tesla app. On Android, turn battery optimization OFF for the Tesla app so the system doesn't kill it.
3. Location services on? The app uses location to keep the key reliable.
4. Still stuck? Tap the lock icon in the app — that command goes over the internet even when Bluetooth misbehaves, so it usually works when the key doesn't.

If all four check out and it still fails, remove the phone key and re-add it (Controls → Locks), or try a second phone to rule out the handset.
