* TOP Battery Endurance* TOP Screen* TOP Software* TOP Gaming
EDITORIAL: This year Vivo meaningfully improved the battery (from 6000mAh to 7000) and upgraded last year's 2x zoom camera to a proper 3x periscope telephoto. Vivo is adding other improvments too making it's IQOO line a true flagship killer. The screen is now as good as any phone's screen with proper Dolby and HDR10+ certification and off-the-chart brightness, added SuperComputing Q3 chip assists the top-of-the-line Qualcomm processor in intensive tasks, OS update promise is now 5 years, a LED ring around the camera island signals notification and battery status, gaming is made even better... This phone is a great option if great imaging is not on your must-have list
PROs
flagship hardware, top SD 8 Elite Gen 5 with UFS 4.1 and Q3-chip-to-assist performance, excellent 2day endurance from a 7000mAh Si-C battery with sub-60min 100W charging (40W wireless). >130nits (going up to 3000nits) bright 510ppi 144Hz LTPO OLED with high frequency dimming and Dolby Vision, IP69 protection, great 50MP 24mm OIS PDAF main + very good (up to 6x zooml 50MP 85mm PDAF periscope tele + average-at-best 50MP 15mm AF ultrawide, 5 years of OS updates, fast USB-C 3.2 port with OTG functionality and great gaming chops
CONs
color changing back panel may not be everyone's cup of tea, unimpressive 32MP non-AF selfie, average (or worse) video recording, no expandable memory, no desktop replacement functionality or even Video Out, limited market availability

* BEST Phone Spring Summer 2024* TOP Screen* TOP Selfie* TOP Video Recording* TOP Software* TOP Desktop Replacement
EDITORIAL: This 2024 phone is that good. Samsung fit everything in there, a stylus, 6 cameras (!), the best screen in the industry and (almost) 24 hours of battery life. In 2024, this was the best phone ever made by the world's biggest phone making corporation. It had the most features too, by far. Samsung also included seven years (!) of OS updates as well as amazing desktop replacement (DeX) software. Consider that at 79 mm wide, this is a "two hands and a bag" phone.
PROs
SnapDragon 8 Gen 3 processor fast performance, 1400+nits 500+ppi LTPO AMOLED with HDR10+, 200MP OIS main + 10MP OIS tele + 50MP OIS tele and a 12MP ultrawide (all with PDAF), 12MP PDAF Selfie, top AI features trickling down with software updates, 7 years of OS updates, stylus with Bluetooth and of course: the DeX feature that may save you from buying a new computer
CONs
size, barely a day of battery endurance with slow charging, lack of expandable SDmemory storage
