Design & build — how it feels
Visual and tactile impression
The Note 40 follows a contemporary aesthetic: a broad camera island, minimalist lines, and a slim profile that emphasizes screen real estate. While the frame is polymer rather than full metal, the finish is refined and comfortable in the hand.
Strengths
- Lightweight for its size — great for long-form reading or streaming sessions.
- Thin bezels and a large display create an immersive viewing canvas.
- In-display fingerprint is fast and reliable in daily use.
Trade-offs
- Plastic frame (not aluminum) reduces perceived premium but helps keep weight down.
- Finish varies across colorways; Pro models sometimes show a more elaborate camera halo.
- IP rating across markets tends to be splash-resistant (e.g., IP54 in select regions) — don’t assume submersion tolerance.
Display — bright, fast, and smooth
The 120Hz AMOLED display is one of the Note 40’s most persuasive selling points. It delivers smooth motion, saturated color, deep blacks, and credible HDR highlights when source material supports it.
Practical display tests to include
- Peak brightness (nits) by APL (2% highlights and 100% white).
- Color gamut coverage (sRGB / DCI-P3) and Delta-E for color accuracy.
- PWM/flicker check to identify potential eye-strain for sensitive users.
- HDR playback verification for YouTube / Netflix streams (check DRM level if you need HD).
- Side-by-side photographic comparison vs a Redmi Note 13 or Galaxy A-series to show color tuning and white balance.
Performance — daily use and gaming
Performance is contingent on the SoC variant. Many units ship with MediaTek Helio G99 Ultimate — a solid mid-range performer — while Pro/5G trims in some territories may use Dimensity chips, giving better single-core and 5G connectivity.
Everyday experience
- Smooth UI, rapid app launches, and reliable multitasking for typical workloads.
- System animations and biometric unlocking feel snappy on 120Hz.
Gaming & sustained load
- Casual and many competitive titles run fine at medium settings. Expect 30–60 minute sessions at stable fps for titles like PUBG Mobile and Call of Duty Mobile on medium-to-high settings.
- Heavier titles at max settings may encounter thermal throttling; include surface temperature readings and throttling graphs in your review..
Camera deep-dive — samples, crops, and advice
This is the high-impact section. The 108MP headline generates clicks — but meaningful buying decisions hinge on how Infinix processes and delivers those pixels.
Hardware fundamentals
- 108MP sensor (some listings name GalaxyCore GC32E1 for certain SKUs).
- Pixel-binning to produce default 12MP/27MP outputs for better low-light performance and acceptable file sizes.
- Ultrawide / tele / macro configurations differ by market — always verify your unit.
Testing methodology
- Capture in Auto and Pro modes; save RAW where possible.
- Use a tripod for night and Pro exposure frames.
- Maintain identical framing for cross-phone 1:1 crops.
- Export EXIF metadata for each sample (ISO, shutter, aperture, lens crop/zoom).
Daylight (1×) expectations
- Excellent fine detail in good lighting courtesy of the high-resolution sensor.
- Default JPEGs may show contrasty sharpening — attractive on social, but examine 1:1 crops for artifacting.
- Dynamic range is competent but can clip highlights in very high-contrast scenes — HDR helps.
Zoom performance
- 2× digital often yields usable detail; beyond 5×–10× images degrade noticeably.
- Recommended: show 1×, 2×, 5× crops to illustrate the graduated loss in fidelity.
Night & low-light
- Night Auto vs Night Pro (tripod): Night Pro offers longer exposures and can preserve texture better while reducing noise.
- Expect noise reduction to sometimes wipe out delicate textures in favor of cleaner-looking results.
Portrait & selfie
- Selfie processing tends to smooth skin — favorable for social audiences.
- Portrait mode provides decent subject separation but can be aggressive at times.
Video
- Typical recording modes: 1080p@60; some SKUs may support 2K or 4K at 30fps.
- Stabilization (EIS) does a fair job while walking; test on a bike or running for real-world stabilization behavior.
Battery & charging — wired vs MagCharge wireless
Battery life and charging behavior are central to the user experience. The Note 40 ships with a 5,000 mAh cell, 45W wired charging, and 20W MagCharge magnetic wireless.
Wired (45W)
- Real-world expectation: 0→~50% in roughly 20–30 minutes, depending on starting temperature and A/C conditions. Wired is ideal for rapid top-ups.
MagCharge wireless (20W)
- Magnetic wireless charging that requires MagCase and MagPad / MagPower accessories.
- Slower than wired but offers a tidy, cable-free experience for desk or car top-ups. Secondary benefit: convenient alignment via magnets.
Recommended battery tests
- 0→100 wired and 0→100 MagCharge wireless curves with timestamps (every 5–10 minutes).
- YouTube 1080p loop endurance at fixed brightness to compare streaming drain.
- 30-minute gaming drain (FPS logged) to show gaming battery impact.
- 24-hour standby test to compare idle drain patterns.
Software, updates & bloat
The phone runs Android 14 layered with XOS 14. XOS brings features and customization, but ships with a regional preinstalled app that some users will consider bloat.
What to look out for
- Region-specific apps and shortcuts on first boot.
- Update cadence for Infinix is historically less generous than major global brands — verify the local guarantee for Android upgrades and security patches.
Connectivity, ports & accessories
Connectivity
- Band support differs by SKU — confirm the exact bands if you rely on specific carrier frequencies (especially for 5G).
- NFC availability is market-dependent — essential for contactless payments in some regions.
Accessories
- MagCase, MagPad, MagPower: describe each’s function and expected cost (or advise to check the official store).
