FOLDSUPERIOR* TOP Battery Endurance* TOP Camera* TOP Selfie* TOP Software

EDITORIAL: (this is a pre-test listing based on reasonable expectation of battery and imaging performance) After China only release, Vivo made an international release of its top foldable on Oct 1st. Featuring the biggest battery and (inner) screen on a foldable, the Fold 6 lands somewhere at the top of 2026 lineup - a serious consideration if available in your market.

PROs
excellent build, fast (top of last gen) Dimensity 9500 Super (3nm) with UFS 4.1 performance, 36hr endurance from a 6900mAh Si-C battery with sub-60min 80W 40W wireless charging, 2 >1300nits >400ppi 120Hz LTPO screens with Dolby Vision, (immersible) IP69 protection, great pics from a 200MP OIS main + 50MP OIS periscope telephoto + 50MP ultrawide (all PDAF) setup, 2 20MP 31mm selfies, good video recording, feature rich and stabile OriginOS with 5 years of OS updates, desktop replacement functionality bundled with Android 17, fast USB-C 3.2 Gen 2 with Display Port
CONs
no AF on selfies but on foldable you can use the main camera for selfies, no expandable memory slot, limited market availability

EDITORIAL: After years of refusing Samsung finally adopted a Silicone Carbon anode tech and the new Z Fold Ultra gets a competitive 5000mAh size battery at last. Along with processor, faster charging, pixel denser screen and a better ultrawide that is where the upgrades end. Still, this phone that re-invented foldables 8 years ago is a flagship affair with excellent software implementation, features and very long OS support.

PROs
slightly smaller despite bigger battery, fast SD 8 Elite Gen 5 with UFS 4.0 performance, >30hr endurance from a 5000mAh Si-C battery with 60min 45W (20W wireless) charging, 2 >1400nits >420ppi 120Hz LTPO AMOLED screens with HDR10+, (submersible) IP48 protection, reliable images from the 200MP 23mm OIS PDAF main + 50MP 13mm PDAF ultrawide, good video recording, feature rich OneUI with 7 years of OS updates, market leading desktop replacement feature, fast USB-C 3.2 port with OTG, global sales and support network
CONs
still lags behind competition in battery autonomy, average 10MP 69mm OIS PDAF telephoto performance, 2 average 10MP selfies with no AF, no expandable memory, Samsung's persistent (Apple-like) effort to lock it's customers into an restrictive ecosystem, poor sounding stereo setup
