Gently pull up on the suction cup while inserting an opening pick into the seam between the display and the frame. Carefully work the pick around the edges to separate the adhesive.

After successful battery replacement, follow these steps for optimal performance:
- Carica iniziale: Fully charge your iPhone to 100% without interruption.

- Prestazioni del monitor: Observe the battery life and charging behavior over the next few days to ensure everything is functioning as expected.
Manutenzione

- Optimal Charging Habits: While full discharge/charge cycles are good for calibration, for daily use, try to keep the battery charge between 20% and 80%. Avoid leaving it at 0% or 100% for extended periods.
- Use Quality Chargers: Always use MFi-certified or original Apple charging accessories.
- Aggiornamenti software: Keep your iOS software updated, as updates often include battery optimization improvements.
