Overview
- Wccftech reports Samsung SDI has de‑prioritized a 20,000mAh dual‑cell silicon‑carbon design and is focusing on 6,000–8,000mAh cells that are showing steadier early yields.
- Testing allegedly flagged stability issues, with the 12,000mAh cell swelling from about 6.3mm to 8.2mm and increasing overall pack thickness to roughly 14mm, with charging reportedly at 100W.
- The trial configuration was said to pair a 12,000mAh primary cell with an 8,000mAh secondary cell measuring about 4mm in thickness.
- GSMArena characterizes the battery claims as rumor from less reliable sources, noting conflicting tips about which cell swelled and suggesting the test unit might not target phones.
- Wccftech also notes continued solid‑state battery research at Samsung SDI and frames Chinese OEM progress in large silicon‑carbon packs as competitive pressure; Samsung has not confirmed these reports.
