About the Honor 400 Smart

The Honor 400 Smart 5G hits a sweet spot that budget phones rarely manage: 5G connectivity, a large 6,500mAh battery, and a 120Hz display, all starting from around 150 pounds. The Snapdragon 6s Gen 3 chip keeps things running smoothly for daily tasks, and the 6.77-inch screen is pleasant to use despite its HD+ resolution. Battery life is the standout feature here, with the massive cell easily lasting two full days under moderate use and potentially stretching further for lighter users. The 50MP main camera is capable in good light, though it lacks the computational photography tricks of pricier phones. Software support through to 2030 is a genuine differentiator at this price, meaning the phone should remain secure and functional for years. IP65 water resistance and SGS-certified drop resistance add practical durability. The compromises are predictable: the HD+ screen lacks the sharpness of full-HD panels, 35W charging is adequate but not fast by modern standards, and the processor will not handle demanding games well. For anyone who values battery longevity and 5G access over raw performance, the 400 Smart delivers where it counts.

Frequently Asked Questions

Is the Honor 400 Smart worth buying?
Yes, particularly if battery life and 5G connectivity are priorities on a tight budget. Starting from around 150 pounds, it offers a 6,500mAh battery that lasts two days, a 120Hz display, and software support until 2030. It is best suited to everyday use rather than gaming or photography.
Does the Honor 400 Smart support 5G?
Yes. The Honor 400 Smart 5G runs on the Qualcomm Snapdragon 6s Gen 3 processor with full 5G support. This makes it one of the most affordable 5G phones available in the UK, giving you faster data speeds and better future-proofing than 4G-only alternatives at similar prices.
How long does the Honor 400 Smart battery last?
The 6,500mAh battery comfortably lasts two full days under moderate usage. Light users may get even more. Charging is handled by a 35W Honor SuperCharge adapter, which is not the fastest available but brings the large battery from empty to full in a reasonable time.
Is the Honor 400 Smart water resistant?
The Honor 400 Smart 5G has an IP65 rating, meaning it is fully dust-tight and protected against low-pressure water jets from any direction. It can handle rain, splashes, and brief exposure to running water but should not be submerged. It also holds SGS certification for drop and crush resistance.
How long will the Honor 400 Smart receive software updates?
Honor has committed to providing major system updates and security patches through to 2030. That is roughly five years of support from its August 2025 launch, which is impressive for a phone at this price and means it will remain secure well beyond typical budget phone support windows.
How good is the Honor 400 Smart camera?
The 50MP main camera takes clear photos in good lighting and handles everyday photography well. A 2MP portrait sensor assists with depth effects, while the 5MP front camera covers selfies and video calls. It is not a camera-focused phone, but it meets the needs of users who primarily share photos on social media.
Is the Honor 400 Lite worth it over the Honor 400 Smart?
The biggest upgrade is the display: the 400 Lite has a 6.7-inch AMOLED screen with 3,500-nit peak brightness compared to the 400 Smart's TFT LCD at 700 nits, delivering far punchier colours and better outdoor readability. You also get a 108MP main camera versus 50MP and six years of software updates instead of five. The Honor 400 Lite starts at £209 SIM-free versus £119 for the 400 Smart. If screen quality and camera detail matter to you, the step up is worthwhile. Compare Honor 400 Lite deals.

Based on main-sensor size (1-inch / 1/1.3" beats 1/2.0"), telephoto reach (periscope > 5x > 3x optical), image processing tier (Apple Pro, Pixel Pro, Galaxy Ultra, Honor Magic Pro, Xiaomi Ultra), pro video features (ProRes, Apple Log, Dolby Vision), camera-partnership branding (Leica, Hasselblad, Zeiss) and OIS. Older flagships are de-rated since image processing pipelines have advanced significantly each generation. Megapixel count is deliberately downweighted — it correlates poorly with real-world camera quality.

Based on battery capacity (mAh) adjusted for platform efficiency calibrated against NotebookCheck, Tom's Guide, GSMArena and CNET reviewer tests. Apple A-series gets +45% (iOS process freezing + LTPO 1Hz + tuned panels make iPhone Pro Max outlast many 6500+ mAh Android phones in measured tests). Top Snapdragon / Dimensity flagships get +15%, budget chipsets are penalised −15% to −25% to reflect less efficient displays and looser background limits. Charging speed is excluded — see the separate Fast charging tag for that.
