Old Flagship with a Twist, or Underrated Classic?
When ASUS launched the Zenfone 6Z, it wasn’t just aiming to compete on specs — it wanted to redefine how a flagship should look and feel. And while the market was flooded with notches and punch holes, ASUS made a bold move — a motorized flip camera. But beyond the wow factor, does the Zenfone 6Z still hold value in 2025, or is it now just a relic of an experimental time?
Let’s dive into our full real-world review, covering everything from design, performance, software, camera, and long-term usability.
1. Design & Build: Unique and Functional
If there’s one phone that still turns heads years after launch — it’s this one.
- Motorized Flip Camera: It’s not a gimmick. The rear camera flips forward to become your selfie camera, ensuring you get the same quality both sides.
- Metal Frame + Glass Back – Premium and solid feel
- No Notch or Punch-Hole – Full-screen, uninterrupted experience
- Weight: 190g — feels light for its size
2. Display: No Compromise Experience
No AMOLED, but that didn’t stop ASUS from delivering one of the most immersive displays of its time.
- 6.4” IPS LCD, Full HD+ (2340 x 1080)
- HDR10 Certified
- Gorilla Glass 6
- No notch = Pure viewing experience
Color accuracy is sharp, contrast is rich, and outdoor brightness is acceptable, though not at OLED levels.
3. Performance: Snapdragon Muscle with Clean Software
Powered by the Snapdragon 855, the Zenfone 6Z still holds up surprisingly well in 2025.
- Chipset: Snapdragon 855
- RAM: 6GB / 8GB LPDDR4X
- Storage: UFS 2.1, up to 256GB + microSD slot
Real-Life Performance:
- No lag in daily usage — Instagram, Chrome, Gmail, YouTube = fast and fluid
- App loading is fast, and multitasking smooth
- Light gaming like CoD Mobile or PUBG still runs well on Medium–High settings
Geekbench Score (2025 Re-Test):
- Single Core: ~760
- Multi Core: ~2700
4. Camera: Flip to Win?
The flip camera is the biggest talking point of the Zenfone 6Z — and rightly so.
- 48MP Sony IMX586 (f/1.8) + 13MP Ultra-Wide
- Laser autofocus, 4K 60fps video
- Same cameras used for selfies via flip
Daylight Shots:
- Great detail and sharpness
- Color is natural, close to real-life tones
- HDR works well, especially with wide-angle
Low Light:
- Decent with Night Mode, but lacks modern AI processing
- Some noise and softness
Video:
- 4K 60fps video is stable and detailed
- Flip module enables creative angles, time-lapse, and motion tracking
5. Gaming: Capable, But Not a Powerhouse
Though Snapdragon 855 still handles most casual games well:
Real-World Gaming Test:
- Call of Duty Mobile: High graphics, 60fps — smooth
- PUBG / BGMI: HDR + Ultra FPS — playable
- Genshin Impact: Struggles on medium — frame dips in busy areas
- Asphalt 9: Runs fine, slight stutter after long session
Thermals: After 45 minutes gaming — gets warm but not hot
Battery Drain: ~15% in 30 min (moderate)
6. Battery Life: True Endurance Champion
One of the most underrated features of the Zenfone 6Z is its massive 5000mAh battery.
- Screen On Time (SOT): 8–9 hours (mixed use)
- Standby time: Excellent — loses only ~3% overnight
- Charging: 18W Quick Charge 4.0
Charging Speed:
- 0–50%: ~40 minutes
- 0–100%: ~1hr 40min
7. Software: ZenUI at its Best
ASUS surprised everyone by moving from a bloated UI to a stock-like, clean ZenUI.
- Android 12 is the final official update
- No ads, no bloat
- Smooth animations, useful customizations (one-hand mode, smart key)
8. Audio, Connectivity & Extras
- Stereo Speakers: Loud and clean, one of the best in its time
- 3.5mm Headphone Jack: Rare today, but present here
- Expandable Storage: Dedicated microSD slot
- Rear Fingerprint Scanner: Reliable and fast
9. Who should buy it
Perfect for you if:
- You love taking selfies or vlogging
- You want a phone with big battery and clean software
- You prefer a notch-free full screen
- You want to save money and get solid performance
Not for you if:
- You need 5G or newer Android updates
- You’re a heavy gamer
- You want AMOLED or 120Hz display
Final Verdict:
The ASUS Zenfone 6Z is not just a phone — it’s a piece of smart design thinking.
Even in 2025, it holds its own because of:
- Innovative camera design
- Clean and fast UI
- Reliable battery performance
