Sony has refined the PS5 Slim without any public announcement. The updates focus on cooling, repairability, and internal efficiency. Newer units, including the Marvel’s Wolverine Limited Edition, use a revised EDM-051 motherboard. A teardown by console technician Modyfikator89 first showed these changes.
For owners, the practical upside is simpler long-term upkeep. Battery swaps become far less invasive, and the cooling setup reduces certain risks that earlier Slim models carried.
The Replaceable CMOS Battery
The most noticeable repairability shift involves the CR2032 CMOS battery. This small battery keeps the console’s internal clock running. If it dies while the system is offline, the PS5 loses its system time. That can prevent digital licenses from verifying and leave saved games unusable.
On earlier PS5 Slim models, swapping the battery required a full motherboard disassembly. The process risked the warranty and forced technicians to handle the liquid metal cooling compound. Newer units change that. Sony adopted a layout similar to the one on the PS5 Pro, placing the battery where it’s accessible without tearing the board apart. When the battery eventually fails, owners can replace it themselves for a couple of dollars instead of shipping the console in for service.
Motherboard Layout and Cooling Updates
Sony also reworked the full motherboard arrangement. Components sit in a simpler layout than before. The cooling system received parallel attention. Liquid metal around the APU is now contained the same way it is on the PS5 Pro. Less surface area contacts the compound directly. That design should lower the chance of leaks during normal use or from vibration.
The heatsink itself uses different construction and materials than earlier Slim versions. Sony also switched to a cheaper, more efficient HDMI retimer chip.
Identifying the Revised Model
The updated hardware reportedly began shipping in September 2026. Units still arrive with the original manual, which says nothing about the new layout or battery access. The only reliable way to confirm what’s inside is to open the console and check.
