Can Overcharging Destroy a PSP? Extremely Unlikely — But It Shortens Battery Life

Extremely unlikely. PSP uses lithium-ion batteries with built-in protection circuits that cut charging at 100%. The charging IC in the PSP also regulates current.

Long-Term Effects of Constant Charging

• Battery degradation: Keeping at 100% 24/7 accelerates capacity loss (typical Li-ion loses 20%/year at full charge vs. 4% at 50%).
• Swelling risk: Rare, but possible if protection circuit fails.

Best Practice

• Charge when battery < 40%; unplug at 80–90% for longevity.
• Use official Sony charger (AC adapter + cradle or USB).
• If storing >1 month, charge to ~50%, remove battery, cool dry place.

Overcharging won't "destroy" the PSP, but it shortens battery lifespan.
