Sony has released firmware update v7.1.7 for the PS Portal Remote Play handheld, which introduces a new battery management feature allowing users to restrict charging to 80%. This update is designed to preserve the long-term health of the device's battery, as regularly charging lithium-ion batteries to full capacity and keeping them plugged in increases stress and chemical wear. The firmware also includes minor improvements to system software functionality and message usability.

The new charge limit option can be found in the device's Settings menu under System > Battery. Users selecting a charge limit above 80% are warned that it may impact battery performance and reduce long-term battery health. Capping charges at 80% is a common practice for extending portable device longevity and is considered worth implementing for a well-regarded accessory like the PS Portal.
