FLY* TOP Software

EDITORIAL: Oppo's 2025 top phone is limited to Chinese market but it is a worth purchase wherever you live. It has all the best phone hardware features and the only letdown are minor software inconsistencies. Performance is top of the charts but the phone will throttle under prolonged, heavy load. Following Apple, there are now 2 new hardware buttons: a Shortcut button and a iPhone-like camera control button with capacitive touch support.

PROs
great build with a Shortcut and a Quick button, top performance scores of the SD 8 Elite combined with UFS 4.1 storage, a 36hr endurance from 6100mAh Silicone anode battery with sub-40min 100W charging (50W wireless), a flat >500ppi sharp HDR10+ screen with high-frequency PWM dimming, IP69 ingress protection, a 50MP 23mm main + 2 50MP (70mm and 135mm) tele lenses (all 3 OIS PDAF) + 50MP 13mm PDAF ultrawide, excellent 32MP PDAF selfie, great video recording, 5 years of updates for stabile and feature rich OS
CONs
being one of the biggest/ heaviest (226gr) phones on the market, relatively low (1100nits) maximum brightness may frustrate you in bright outdoors light, lack of expandable storage & desktop replacement feature, stereo speakers could have been louder

EDITORIAL: Like other Cheese phone makers, Vivo is going small. This years X vanilla model is 2mm narrower and almost 10mm shorter to put X300 well into the new "compact size" of 72mm or less. The battery is bigger than before and the Zeiss branded camera system Vivos are known for is also upgraded. It now features a new 200MP main and a new 50MP AF selfie. The built is improved as well with silky finish both on the back glass panel and on a (squarish, iPhone-like) aluminium frame.

PROs
compact and flagship built, very fast Dimensity 9500 with UFS 4.1 performance, >30hr endurance from a 6040mAh Si battery with sub-60min 90W charging (40W wireless). >1600nits bright 450ppi LTPO AMOLED screen with >2000Hz PWM and HDR10+ certification, IP69 protection, excellent pics from Zeiss optics 200MP 23mm OIS PDAF main + 50MP 70mm OIS PDAF 3x periscope telephoto + 50MP 15mm AF ultrawide, new 50MP 20mm AF selfie and up to 4 years of mature and stable OS updates
CONs
limited market availability, no SDmemory slot, no desktop replacement feature or video-out, Vivo trails Samsung, Pixel and Honor in AI implementation
