The figures were also reported by Gizmochina<\/a>, which noted that both devices are expected to support 100W charging. Neither Poco phone has been officially announced, so the battery capacities should still be treated as leaked specifications rather than final retail details.<\/p>\n The comparison with the Redmi models is where the story becomes significant.<\/p>\n How the Batteries Compare to Redmi K100<\/p>\n The Poco F9 Pro is reportedly based on the Redmi K100 Pro, while the F9 Ultra is expected to share its hardware with the Redmi K100 Pro Max. That would give Xiaomi a familiar playbook for taking China-first hardware to international markets, but the battery reductions are unusually large for the Pro model.<\/p>\n ModelReported Poco batteryRedmi counterpartDifferenceCapacity cutPoco F9 Pro6,330mAhRedmi K100 Pro at 8,580mAh2,250mAh26.2%Poco F9 Ultra8,050mAhRedmi K100 Pro Max at 9,070mAh1,020mAh11.2%<\/p>\n The F9 Pro would therefore lose more than one in every four milliamp-hours available in the Redmi version. The F9 Ultra\u2019s reduction is easier to absorb because an 8,050mAh battery would remain unusually large for a global flagship phone.<\/p>\n The 100W charging support helps reduce the inconvenience of a smaller battery because users can top up quickly. It does not remove the underlying trade-off, though. Faster charging shortens the time needed to refill a phone, while a smaller battery still means fewer hours between charges under the same workload.<\/p>\n Xiaomi Has Repeated This Battery Pattern<\/p>\n The Poco F9 leak is not an isolated example. Xiaomi has repeatedly shipped global Poco versions with smaller batteries than their Redmi equivalents in China. The gap has generally widened across recent generations.<\/p>\n Poco modelPoco batteryRedmi equivalentRedmi batteryCapacity cutPoco F5 Pro5,160mAhRedmi K605,500mAh6.2%Poco F6 Pro5,000mAhRedmi K705,500mAh9.1%Poco F7 Ultra5,300mAhRedmi K80 Pro6,000mAh11.7%Poco F8 Pro6,210mAhRedmi K907,100mAh12.5%Poco F8 Ultra6,500mAhRedmi K90 Pro Max7,560mAh14.0%Poco F9 Pro*6,330mAhRedmi K100 Pro8,580mAh26.2%Poco F9 Ultra*8,050mAhRedmi K100 Pro Max9,070mAh11.2%<\/p>\n *Leaked capacities that remain unconfirmed.<\/p>\n Across this comparison, the average gap is roughly 13%. The F9 Pro would represent the largest reduction yet if the leak is accurate. That makes this more than a routine regional adjustment. It suggests that the global version may be designed around different component availability, regulatory requirements, thermal targets or product positioning than the Chinese model.<\/p>\n Xiaomi has not explained why the batteries differ. The existence of the gap across multiple generations does show that the change is part of the global product strategy rather than a one-off specification mistake. It also means buyers should not assume that a Poco phone will match every major hardware feature of its Redmi counterpart.<\/p>\n Poco F9 Pro and F9 Ultra Expected Specs<\/p>\n Current reports point to the F9 series carrying over much of the Redmi K100 hardware. Gizmochina\u2019s report<\/a> lists a 6.59-inch display for the Pro and a 6.9-inch panel for the Ultra. Both are expected to use 1.5K AMOLED screens with a 185Hz refresh rate.<\/p>\n SpecificationPoco F9 ProPoco F9 UltraDisplay6.59-inch 1.5K AMOLED at 185Hz6.9-inch 1.5K AMOLED at 185HzChipsetSnapdragon 8 Elite Gen 5 V-series, unconfirmedSnapdragon 8 Elite Gen 5 V-series, unconfirmedRAM and storageUp to 16GB LPDDR5X and 1TB UFS 4.1Up to 16GB LPDDR5X and 1TB UFS 4.1Main camera200MP Samsung HP5200MP Samsung HP5Telephoto50MP periscope with 2.5x zoom50MP periscope with 5x zoomUltrawide camera8MP50MPBattery6,330mAh, leaked8,050mAh, leakedWired charging100W100WWireless chargingUnconfirmed50W, reported by certification coverage<\/p>\n The chipset information needs extra caution. Earlier certification reports suggested that the F9 Ultra could use a newer Snapdragon 8 Elite Gen 6 Pro chip, while newer battery coverage points to the Snapdragon 8 Elite Gen 5 V-series for both devices. Until Poco publishes an official specification sheet, the processor should not be treated as settled.<\/p>\n Readers can compare the current F9 expectations with Memeburn\u2019s earlier coverage of the Redmi K100 Pro\u2019s leaked specifications<\/a> and the more recent Redmi K100 Pro report<\/a>. Those reports also show why the Redmi-to-Poco relationship matters. The global phones are expected to preserve the performance-focused hardware while making changes that could affect endurance and pricing.<\/p>\n Poco F9 Pro Release Date and Price<\/p>\n Poco has not announced a release date or price for either model. However, both phones have appeared in international certification databases, including Singapore\u2019s IMDA and Indonesia\u2019s SDPPI. Notebookcheck<\/a> also reported listings in Taiwan\u2019s NCC database, including 100W wired charging for both models and 50W wireless charging for the Ultra.<\/p>\n The certification activity points to a global launch window in late 2026. Earlier reporting based on the timing of the Poco F8 series suggested that October could be possible, but there is still no official event date. The current evidence supports a launch before the end of 2026 more strongly than a specific month.<\/p>\n![\"Poco](\"https:\/\/www.newsbeep.com\/ie\/wp-content\/uploads\/2026\/08\/Poco-F9-Pro-and-F9-Ultra-battery-comparison-with-Redmi-K100.jpg\")
