Samsung is reportedly developing high-capacity batteries that could significantly extend smartphone battery life. Leaked reports suggest the company is testing advanced silicon-carbon battery technology with capacities of up to 12,000 mAh and 18,000 mAh. These batteries use new dual-cell and triple-cell designs that aim to store more power without making phones thicker.
The testing is being conducted by Samsung SDI, the battery manufacturing division of Samsung Electronics. The company is also improving battery management software and thermal control systems to ensure better safety, efficiency, and durability.
Samsung has been cautious with battery innovation since the issues related to the Samsung Galaxy Note 7 in 2016. Because of that incident, the company is taking extra steps to test new battery technologies before launching them in commercial smartphones.
Samsung High-Capacity Batteries May Use Silicon Carbon Technology
The new Samsung high-capacity batteries are based on silicon carbon (Si C) technology. Unlike traditional lithium ion batteries that use graphite anodes, silicon carbon batteries use a silicon based anode. This allows the battery to store more energy in a smaller space.

Several smartphone brands have already started using this technology to increase battery capacity while maintaining slim phone designs.
Reports suggest Samsung even tested a 20,000mAh prototype battery, but it failed durability testing after about 960 charge cycles. Because of this, the company is currently focusing on slightly smaller capacities such as 12,000mAh and 18,000mAh.
Details Of These Battery Prototypes
Leaked information reveals several prototype battery configurations currently under evaluation.
12,000mAh Prototype (Dual Cell Design)
- 6,800mAh primary cell with around 4.7mm thickness
- 5,200mAh secondary cell with about 3.2mm thickness
- Combined target thickness: under 9.3mm
18,000mAh Prototype (Triple Cell Design)
- 6,699mAh cell with 4.2mm thickness
- 6,000mAh cell with 3.9mm thickness
- 5,257mAh cell with 3.28mm thickness
- Target stacked thickness: around 12.3mm
The company reportedly aims to achieve a battery lifespan of about 1,500 charge cycles for these prototypes. If development succeeds, the 12,000mAh version could deliver around 20 to 25 hours of screen on time on a smartphone connected to mobile data and Wi Fi.
These Samsung high-capacity batteries could eventually power future flagship phones and foldable devices without increasing device thickness, though the technology is still in the testing stage.
