* 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
Samsung Galaxy S25

FLY* TOP Selfie* TOP Software* TOP Desktop Replacement
EDITORIAL: S25 is taking on other flagship phones with excellent (very pocketable) build, great screen, good cameras, excellent selfie and of course: DeX -the best desktop replacement software there is. This year, Samsung is focusing on the software side, adding tons of features meant to set it apart. The battery tests confirmed our expectations: S25 offers no improvement over S24's mediocre battery life and charging performance. S25 is not bad but what a shame to have to worry about topping up your phone before going out in the evening.
PROs
just 70mm wide, fast SnapDragon 8 Elite performance, 1400+nits bright >410ppi 120Hz LTPO AMOLED screen with HDR10+, very good 50MP 24mm OIS AF main + 10MP 67mm OIS AF tele + 12MP 13mm ultrawide setup, excellent 12MP 26mm PDAF Selfie, leading AI features, 7 years of OS updates and DeX software that can save you so much money, fast USB-C 3.2 with Display Port and OTG, global availability and service
CONs
less-than-a-day battery endurance, fixed focus ultrawide is it's imaging weakness, no expandable storage
