Key Highlights

• Poco F9 Pro may feature a 6,330mAh battery, smaller than the Redmi K100 Pro's 8,580mAh cell.
• Poco F9 Ultra could include an 8,050mAh battery, less than the Redmi K100 Pro Max's 9,070mAh.
• Both Poco models are expected to retain 100W wired fast charging despite reduced battery sizes.
• Redmi K100 Pro and Pro Max offer high-end displays, Snapdragon 8 Elite Gen 5 chips, and 200MP cameras.

Battery Specifications Revealed

A tipster on X has shared details about the batteries in the upcoming Poco F9 Pro and F9 Ultra. The Poco F9 Pro is expected to include a 6,330mAh battery. This capacity is a notable decrease from the 8,580mAh battery found in the Redmi K100 Pro, which the F9 Pro is reportedly based on. The Poco F9 Ultra may feature an 8,050mAh battery, which is also smaller than the 9,070mAh battery in the Redmi K100 Pro Max, its likely counterpart.

Despite the reduction in battery size, both Poco models are expected to support 100W wired fast charging. This feature could help offset the smaller battery capacities by reducing charging times.

Comparison with Redmi Models

The Redmi K100 Pro, which serves as the basis for the Poco F9 Pro, features a 6.59-inch AMOLED display. It is powered by Qualcomm's Snapdragon 8 Elite Gen 5 V chipset and includes a 200MP primary rear camera. The Redmi K100 Pro Max, likely the foundation for the Poco F9 Ultra, offers a 6.9-inch AMOLED display. It runs on the standard Snapdragon 8 Elite Gen 5 processor and is equipped with a 200MP main camera and a 50MP periscope telephoto unit.

Both Redmi models also include a Bose-powered rear woofer, enhancing audio performance. These hardware features may carry over to the Poco-branded versions, though the main difference appears to be in battery capacity.

Expected Launch and Market Position

The Poco F9 Pro and F9 Ultra have appeared on several certification websites, suggesting an imminent launch. While the battery capacities are smaller than those of their Redmi counterparts, the inclusion of 100W fast charging may appeal to users seeking quick recharging capabilities. Further details about display size, processor, and camera specifications are expected to be confirmed at launch.
