Samsung Galaxy S27 Series RAM and Storage Leaks: LPDDR6 RAM for Pro and Ultra

The Tech TL;DR:

• Tiered Memory Architecture: Premium models such as the Galaxy S27 Pro and Galaxy S27 Ultra are slated to adopt faster LPDDR6X RAM and UFS 5.1 storage, while the base Galaxy S27 and S27+ will use LPDDR5X memory to mitigate rising component expenses.
• Configuration Layout: The base Galaxy S27 and S27+ start at a baseline of 12GB RAM paired with 256GB of storage, while the top-tier Ultra introduces a maximum configuration of 16GB RAM and 1TB ROM.
• Power and Charging Milestones: Recent regulatory filings in China indicate battery capacities of 5,200 mAh for the Pro and 5,700 mAh for the Ultra, with both supporting 60W wired charging.

Hardware Breakdown and Cost Mitigation Strategies

Samsung originally evaluated equipping every device in the upcoming Galaxy S27 series with advanced LPDDR6X RAM. However, due to the elevated cost of manufacturing these next-generation memory chips, the vendor adjusted its deployment strategy. According to reports from The Bell, the base Galaxy S27 and Galaxy S27+ will retain LPDDR5X RAM to prevent prohibitive price increases on entry-level flagship tiers.

Conversely, the high-performance variants—the Galaxy S27 Pro and the Galaxy S27 Ultra—are planned to incorporate LPDDR6X RAM and UFS 5.1 storage standards.

Complete Lineup Configurations

The leaked documentation outlines specific memory and storage pairings across all four models:

• Galaxy S27: 12GB RAM with 256GB ROM; 12GB RAM with 512GB ROM.
• Galaxy S27+: 12GB RAM with 256GB ROM; 12GB RAM with 512GB ROM.
• Galaxy S27 Pro: 12GB RAM with 256GB ROM; 12GB RAM with 512GB ROM; 12GB RAM with 1TB ROM.
• Galaxy S27 Ultra: 12GB RAM with 256GB ROM; 12GB RAM with 512GB ROM; 16GB RAM with 1TB ROM.

As noted in coverage from AndroidHeadlines, the vanilla Galaxy S27 finally abandons the 128GB baseline by starting at 256GB storage. Meanwhile, the newly introduced Pro model inherits the 1TB storage ceiling from the Ultra tier but pairs it exclusively with 12GB of RAM.

Power Delivery and Regulatory Filings

Complementing the memory leaks, recent Chinese regulatory filings highlight physical hardware improvements for the upper-tier devices. As detailed by GSMArena, the Galaxy S27 Pro will house a 5,200 mAh battery cell, whereas the Galaxy S27 Ultra steps up to a 5,700 mAh capacity. Both devices are certified for 60W wired charging speeds.

Because these hardware details originate from supply chain leaks and regulatory databases rather than official Samsung announcements, enterprise buyers and consumers should treat the configurations as unconfirmed preliminary specifications subject to change ahead of the formal production release.

Forward-Looking Architecture

Enterprise procurement teams planning large-scale device refreshes should monitor upcoming official announcements from Samsung to verify final regional availability, pricing structures, and long-term security support lifecycles.
