It's surprising that despite the single core performance advantage of the A15 bionic on the iPhone 13 Pro Max, the Dimensity 8400 on the Poco X7 Pro performs overall better than the former despite being a midrange chipset. Talk about an iPhone 13 Pro Max priced at $600 refurbished compared to a Poco X7 Pro that would be priced at $400 yet the latter offers better gaming performance. Kudos to Android chipsets slowly overtaking Apple chipsets

OioiHello, Poco X7 pro: 12 gb LPDDR5X ram, 512 gb UFS 4.0 storage alongside with Silicon carbon 6000mah battery. Also liquid cool technology 4.0 (flagship level cooling system) for 350โ‚ฌ...Meanwhile Iphone 15 pro max 1.500โ‚ฌ for 8gb ram and 256 storage...also common li-ion battery...Before saying what components cheap android phones use, firstly think what iphone offers for 3x and 4x the price. And don't u dare say anything about Poco problems with motherboard. This problem has been fixed since Poco x4. Take care apple fanboy!
