What reviewers say

Distilled from the video reviewers — the score, what they praise, where they push back.?

iPhone 15
across 5 reviews
3.5/5
divided
Reviewers praise
  • Frosted satin glass back feels premium, resists fingerprints well, and is comfortable to hold with softened rounded edges
  • 48-megapixel main camera delivers image quality that rivals higher-tier models, with strong low-light performance
  • A16 Bionic chip provides top-tier CPU performance with consistent gaming frame rates and negligible CPU throttling
Reviewers push back
  • 60Hz display is a widely noted limitation at this tier — animations feel less smooth and always-on display is absent
  • USB-C runs at USB 2.0 speeds, making large file transfers slow and identical in speed to the old Lightning port
  • No telephoto lens means zoom quality degrades noticeably beyond 2x
The iPhone 15 is a solid, well-built phone with a genuinely improved main camera and comfortable design, but reviewers widely agree it is deliberately held back by a 60Hz display and USB 2.0 speeds.
— best for: Someone upgrading from an older iPhone who wants a comfortable, pocketable device with a great main camera, strong performance, and a premium feel without needing the highest refresh rate or optical zoom.
Zenfone 11 Ultra
across 5 reviews
3.5/5
divided
Reviewers praise
  • Exceptional battery life that outperforms most comparable flagships in screen-on-time tests
  • 6-axis hybrid gimbal stabilizer delivers impressively steady video, especially for users with unsteady hands
  • Headphone jack retained, a rarity among large-screen flagships
Reviewers push back
  • Gimbal stabilizer overcompensates under extreme motion, producing visible jitter compared to top rivals
  • Only two guaranteed major OS updates for a premium device, which reviewers broadly criticise
  • Camera processing applies aggressive sharpening and can oversaturate images; telephoto beyond 3x drops off sharply
A large, well-built flagship that impresses on battery life, stabilized video, and AI features, but disappoints fans of the compact Zenfone form factor and offers only middling camera processing and limited software update guarantees.
— best for: Someone who wants a large-screen Android flagship with outstanding battery endurance, genuine gimbal-stabilised video, a headphone jack, and capable on-device AI, and can accept a modest camera processing tier and short OS update window.

Whether the 60Hz display actually matters to real users divides reviewers — some handed test subjects both refresh rates and they could not tell the difference, while others who use 120Hz daily found the 15 noticeably sluggish from day one

Camera quality divides reviewers: SuperSaf and Android Authority find colours natural and dynamic range solid, while GSMArena and Tech Spurt note overprocessing, excessive sharpening, and saturation issues

I have always loved Asus for the functionality. It does everything I need it to do. This phone is larger than my last but so sturdy and still easy to hold and use with one hand. Finally getting my hands on tech such as eSIM and wireless charging which were not available on my previous Asus phone. Overall very happy with my purchase. Cherrytree · asus.com
