Amazfit ActiveMax Review and User Experience
Ms. GadgetWhat was it like to actually use? Please share your honest impressions.
Mr. GadgetOverall, the impression is that it “strikes a balance between a wealth of features and ease of use.” Let’s take a closer look at each function.
Design and Build Quality
The Amazfit ActiveMax case is a combination of aluminum alloy and fiber-reinforced polymer. From the front, it has a round form with a diameter of approximately 48.5mm, a calm design that has presence without being too flashy.
It features two physical buttons on the side. Operation is a combination of touch and buttons, allowing for button control even when wearing gloves or in outdoor environments.
The body color is a single black. The band is made of silicone and supports a wide range of wrist sizes from 135 to 210mm. The 22mm quick-release mechanism makes it easy to swap with commercially available 22mm wide bands.
Display (1.5-inch AMOLED・3,000 nit)
Ms. GadgetHonestly, I’m not sure if 1.5 inches is large or small…
Mr. Gadget1.5 inches falls into the “slightly larger” category. It’s a practical size that makes maps and notification text easier to read.
The 480×480 resolution and 323 PPI directly contribute to sharp text. Actual displays render fine text without jagged edges, making it easy to read even during quick checks during sports.
Notably, it boasts a maximum brightness of 3,000 nit (up to 2,000 nit in auto-brightness mode). This ensures sufficient visibility even outdoors on a sunny day. It also features automatic brightness adjustment, switching to a more eye-friendly brightness level indoors.
Operability・Zepp OS・AI Voice Operation “Zepp Flow”
Zepp OS 5.5 has a simple configuration that allows access to widgets, notifications, and quick settings via swipe gestures from the home screen. The app list can be displayed in either list or grid format, and the more than 170 sports modes are organized hierarchically, making it easy to find the desired mode quickly.
Zepp Flow is an AI voice assistant feature integrated with GPT-4o. It allows for hands-free operation via the built-in speaker and microphone, responding to natural language queries such as “What’s the weather today?” or “Show me my running records.” While Japanese recognition accuracy varies depending on the usage environment and speaking style, it generally operates as intended for short commands.
Ms. GadgetHaving GPT-4o in a smartwatch is amazing. In what situations would you actually use it?
Mr. GadgetIt proves powerful in situations where it’s difficult to take out your smartphone, such as while cooking, driving, or at the gym. Its primary use is giving short voice commands like “Set a 3-minute timer” or “Record my heart rate.” I found it more convenient for simple operational instructions than for complex questions.
Health and Fitness Features (BioCharge™・Heart Rate・SpO2)
The core of the health sensors is the BioTracker™ 6.0 PPG sensor, which supports 24-hour continuous monitoring of heart rate, blood oxygen level (SpO2), and stress level. It can also measure sleep score, deep sleep, and REM sleep during bedtime.
Strength training tracking has also been enhanced, automatically recognizing 25 types of exercises and recording sets, reps, and rest times. This is a practical feature for gym users.
Ms. GadgetHow accurate are the blood oxygen level (SpO2) readings?
Mr. GadgetSince it is not a medical device, the purpose is to “understand trends” rather than exact numerical accuracy. By measuring under the same conditions (at rest, same finger) daily, it is suitable for tracking changes from your own baseline values.
GPS Accuracy・5-Satellite Support・Ski Map (10,000 Locations Worldwide)
The GPS system employs five satellites: GPS, GLONASS, Galileo, BDS, and QZSS (Michibiki), along with a circularly polarized GPS antenna. This design makes it easier to acquire satellites even in urban areas with building shadows or among trees.
The actual GPS acquisition speed is fast, with quick initial positioning outdoors. Track recording during running and cycling shows minimal deviation from the actual course, allowing for confident use in terms of accuracy.
Another feature is the offline map function, which utilizes the 4GB of storage. By downloading map data in advance, navigation can be used even in mountains without signal. The ski map supports over 10,000 resorts worldwide, based on data from opensnowmap.org.
Battery Life (Up to 25 days・64 hours continuous GPS)
The official specifications state up to 25 days for standard use, up to 13 days for heavy use (continuous heart rate monitoring + frequent notifications), and up to 64 hours in GPS mode.
In actual use, even with continuous heart rate monitoring, sleep tracking, and smartphone notifications turned on, it could be operated on a charging cycle of once every 1-2 weeks. The infrequent charging is a significant advantage.
Charging is magnetic; simply attach the dedicated cable to the back of the case. Charging time is approximately 2 hours, with the 0% to 100% time being within a realistic range.
Ms. GadgetThere’s an image that GPS tends to drain battery quickly, but does 64 hours last quite a long time?
Mr. GadgetYes, it lasts. Even if you run a full marathon (approx. 4-5 hours) every day, it would equate to 12-16 days of continuous GPS use by simple calculation. This figure is more than sufficient for ultramarathons, multi-day hikes, or skiing.
Speaker・Microphone・Podcast Function
The Amazfit ActiveMax supports voice operation and hands-free calling. When connected to a smartphone via Bluetooth, you can answer incoming calls using only the smartwatch.
The podcast function is provided via a software update, allowing episodes saved on the 4GB storage to be played via Bluetooth-connected earphones without a smartphone. This feature is very useful when you don’t want to carry extra devices during a run.
Lack of Suica Support・About Payment Functions
Ms. GadgetCan’t I use Suica or PASMO? That’s inconvenient…
Mr. GadgetIt does not support FeliCa (NFC Type-F) in Japan. As Amazfit is a global model, supporting Japan-specific standards is challenging. While it supports Zepp Pay (Mastercard tap-to-pay) in Europe, its availability in Japan is yet to be determined. This is an important point for those who frequently use Suica in their daily lives.
For those whose daily life revolves around public transport IC cards, the lack of Suica support is something to be aware of before purchasing. However, if primarily used for sports and outdoor activities, this point has little impact. Keep in mind that it is not suitable for those who want to complete their daily tap-to-pay transactions solely with their smartwatch.
App Integration (Zepp App)
Integration with your smartphone is done via the Zepp App. It supports Android 7.0 or higher and iOS 14.0 or higher, meaning it can be used without issues with most recent smartphones.
The Zepp App allows for detailed health data review, sports record summaries, watch face customization, and app additions. The UI supports Japanese, and operating the settings screen is intuitive.
Summary
The Amazfit ActiveMax is a “cost-effective smartwatch that balances outdoor use with AI”
The Amazfit ActiveMax is a model that boasts “Five MAXes”: a 1.5-inch AMOLED (3,000 nit), 5-satellite GPS, 658mAh battery, 4GB storage, and Zepp Flow AI voice operation, covering a wide range of needs from sports users to daily use.
Its greatest strength is the “combination of 64 hours of continuous GPS and up to 25 days of battery life,” offering peace of mind to continue using it without worrying about charging during outdoor, sports, and travel scenarios. The ski map for over 10,000 locations and offline navigation are practical differentiating points for users with active lifestyles.
On the other hand, three points—lack of Suica/PASMO support, 512MB music storage, and a weight of 56g (including band)—may be concerns depending on the intended use. If your priority is to “pass through ticket gates with an IC card smartwatch” or “minimize wrist burden,” we recommend checking these points before purchase.
