The HONOR Watch 4 is a rectangular smartwatch with a 1.75-inch AMOLED display, Bluetooth calling, wellness tracking, and a manufacturer-rated battery life of up to 14 days. That battery figure depends on HONOR’s stated usage scenario, and actual endurance varies. It may suit buyers seeking a large screen and basic smartwatch features, but the available evidence does not establish how it compares with rivals in real-world performance.
This review summarizes verified specifications and the limits of the available evidence. There was no hands-on test for this review, so it does not make independent claims about sensor accuracy, outdoor readability, GPS precision, charging time, or competitor performance.

Screen and design
HONOR lists a 1.75-inch AMOLED screen with 390 × 450 resolution and a refresh rate of up to 60Hz. These are manufacturer specifications; they do not by themselves establish how bright or readable the display is outdoors. The rectangular format is a key part of the product’s appeal, but whether it suits you is a matter of preference.
The official specifications list a silicone-rubber strap and one physical button. The available research does not verify measured comfort, scratch resistance, or the fit and finish in extended use.

Battery life: what HONOR claims
HONOR specifies a 451mAh battery and rates the Watch 4 for up to 14 days of typical use. That estimate is based on a defined scenario, not a guarantee for every owner. HONOR’s example includes continuous heart-rate measurement in Smart mode and Healthy Sleep; 30 minutes of Bluetooth calls and 30 minutes of music per week; 90 minutes of GPS exercise per week; daily notifications consisting of 50 messages, 6 incoming calls, and 3 alarms; and 200 screen activations per day.
HONOR cautions: “The actual battery life varies depending on usage habits of users.” — HONOR, official Watch 4 specifications page.
Independent evidence is limited. Wareable reported that battery performance largely matched the claim in its reviewer’s use and observed roughly a 10% battery drop during an outdoor run lasting just over an hour. That is one reviewer’s observation, not a controlled test or a general estimate of GPS runtime.

Health and fitness features
HONOR lists continuous heart-rate monitoring, blood oxygen, stress, sleep, and workout features. It describes an optical microlens-array design intended to improve heart-rate measurement; this is a manufacturer design claim, not independent proof of accuracy. HONOR also says the watch is not a medical device and that health-management data and results are for reference.
The available research does not establish clinical accuracy or comparative performance for heart rate, blood oxygen, sleep, GPS, or workout tracking. Treat the health features as wellness tools, not as a basis for diagnosis or treatment.
Can you swim with the HONOR Watch 4?
HONOR specifies 5ATM water resistance under ISO 22810:2010 and says the Watch 4 is suitable for pool swimming, seaside swimming, and shallow-water activities. It is not simply “waterproof”: HONOR excludes underwater diving, hot showers, saunas, hot springs, and other deep-water activities involving high-speed water flow. Follow the manufacturer’s guidance for your planned activity.

These stated requirements do not establish that every feature works the same way across all phone models, regions, or software versions. Check compatibility for your specific phone and market before buying.
HONOR’s listed hardware includes GPS and Bluetooth 5.2. The evidence available for this review does not establish route accuracy, notification behavior across apps, or feature-by-feature differences between iPhone and Android. Confirm the functions you need with HONOR’s current information for your region.
