* TOP Performance* TOP Battery Endurance* TOP Gaming* TOP Software* TOP Screen
EDITORIAL: (this is a pre-test listing based on reasonable expectation of battery and imaging performance) Vivo decided to adjust to tough market conditions by sacrificing LTPO tech while adding a massive battery. Despite "big and heavy", this is one of the best gaming phone options out there.
PROs
blazing SD 8 Elite Extreme Gen 6 (2nm) with UFS 4.1 performance, >42hr endurance from a 8400mAh Si-C battery with sub-60min 100W (40W wireless) charging, excellent >1300nits 508ppi 165Hz AMOLED screen with Dolby Vision, IP69 protection, good overall 50MP main + 50MP periscope telephoto (both OIS PDAF) + 50MP AF ultrawide setup, average 32MP 21mm non-AF selfie, average video recording, feature rich OriginOS with 5 years of OS updates, fast USB-C 3.2 with OTG
CONs
big & heavy, no LTPO drains battery faster, non-AF selfie, no memory expansion slot, no desktop replacement functionality provided by Android 17, limited market availability
Vivo X300 Ultra

SUPERIOR* TOP Software* TOP PHOTO/VIDEO
EDITORIAL: Unlike X200 Ultra, the X300 Ultra is sold outside of China. Vivo is delivering it's finest camera-phone by putting a double 200MP sensor camera (industry first) and offering not one but two optional tele lenses (a 200mm and a 400mm). Lens coating is still by Zeiss but like with other current Vivo's phones: all other camera tech (hardware and software) is home grown.
PROs
solid build, top Snapdragon 8 Elite Gen 5 with UFS 4.1 performance, >30hr endurance from a 6600mAh (6400 in EU) Si-C battery with sub-50min 100W (40W wireless) charging, outstanding 144Hz LTPO AMOLED screen with >500ppi, Dolby Vision and >1900nits brightness, IP69 protection, outstanding imaging from 200MP 35mm main + 200MP 85mm periscope telephoto + 50MP 14mm ultrawide (all with OIS PDAF) setup, additional 200mm and 400mm Zeiss zoom lenses, excellent 50MP 24mm AF selfie, great video recording, 5 years of feature and AI tricks rich OriginOS updates, fast USB-C 3.2 with DisplayPort and OTG
CONs
big and >230g hefty, hard to use one hand, battery endurance could be better for a phone this size and with LTPO screen, no expandable memory slot, no desktop replacement functionality, very expensive
