Factors Behind Limited Charging Speed

Samsung hasn't officially addressed this limitation, but contributing factors likely include:

1. Thermal management: The thin foldable design limits heat dissipation
2. Display protection: Excessive heat could affect flexible AMOLED longevity
3. Battery health: Slower charging typically preserves long-term battery capacity

25W charging works well for:

• Overnight charging routines
• Top-ups during work or meals

Situations where faster charging would help:

• Quick power-ups before leaving home
• Heavy usage days requiring multiple charges
• Travel with limited charging time
