Do this

  1. Keep charge ~20–80% for daily use.

  2. Avoid heat (cars, pillows, sunny dashboards).

  3. Fast-charge only when needed; otherwise use a lower-watt charger.

  4. Wireless is fine—if it gets warm, switch to cable or remove thick cases.

  5. Overnight is OK with Optimized/Adaptive Charging enabled.

  6. Travel tips: small top-ups (30–70%), USB-C PD power bank, airflow around the phone.

  7. Use certified chargers & quality cables—safer, steadier, longer-lasting.


Myths (skip these)

  • “Always 0–100%.” → Partial charges are healthier.

  • “Fast charging kills batteries.” → Heat is the issue; modern phones manage current.

  • “Wireless ruins batteries.” → Misalignment/heat, not the tech itself.
