Design and Comfort
The Amazfit Bip 6 and GTS 4 Mini have notably different looks. The Bip 6 has a slightly larger, round-ish body with a lightweight aluminum frame and a smooth plastic back.
You’ll find it in a variety of colors (e.g., bold copper-orange “Lava” or classic black), all fitted with a comfortable silicone strap.
The strap is flexible and comes with a simple clasp, very comfortable to wear, though a bit tricky to buckle every time. It only weighs 27.9 g (without the strap), making it feel unobtrusive even during exercise.
The GTS 4 Mini, on the other hand, prides itself on being ultra-thin and light. It has a sleek rectangular body with a metallic middle frame, and Amazfit stresses its “ultra-slim and light design”.
GTS 4 Mini is only 9.1 mm thick and about 19 g without the strap. It truly feels feather-light.
The GTS 4 Mini’s strap is also silicone, but it’s designed with a more refined metal clasp and extra loops for a snug fit.
You can find this strap a bit more premium and secure than the Bip 6’s. Overall, the Mini’s slim profile makes it very low-profile on the wrist – ideal if you want something that slides easily under sleeves.
Both watches have 5 ATM water resistance (up to 50 m) and a similar aluminum/silicone build.
The Bip 6 offers a larger case and display, which some may find more modern and easier to read, while the GTS 4 Mini is thinner and lighter, edging out comfort by a small margin.
If you prefer a bigger screen and don’t mind a slightly chunkier watch, the Bip 6 shines. If subtlety and sleekness matter more, the GTS 4 Mini is likely more your style.
Screen and Display
The Bip 6 and GTS 4 Mini both have bright AMOLED screens, but the Bip 6’s is bigger.
The Bip 6 sports a 1.97-inch AMOLED display with a high 380×450 pixel resolution with vibrant colors and excellent contrast, and it can reach a peak brightness of about 2000 nits.
In practice, this means the Bip 6 remains very readable even in direct sunlight – a nice bonus if you often check your watch outdoors.
The GTS 4 Mini has a 1.65-inch AMOLED screen at 336×384 pixels (about 309 PPI). That resolution is slightly lower, but still sharp for normal wristwatch distances.
With 500 cd/m² peak brightness, it handles sunny conditions without much trouble. The Mini’s screen is flat (no curve) to save thickness, whereas the Bip 6’s screen is gently curved.
Both have an always-on display mode so you can glance at the time without waking the screen.
Overall, the Bip 6 has the advantage in sheer size and maximum brightness, giving it about 5–7% better screen real estate.
Both screens look excellent in day-to-day use – crisp text and colorful watch faces – but if you value a big, bold display, the Bip 6 takes the advantage.
The GTS 4 Mini’s display is slightly smaller, yet still ample and perfectly adequate for notifications and fitness stats.
Storage and Apps
Under the hood, these watches take very different approaches to storage. The Amazfit Bip 6 has 512 MB dedicated internal memory for apps, music, and maps. So you can use it to load music files or offline map data.
In short, the Bip 6 can function fairly independently. It even has an on-watch app store (through Zepp OS) supporting popular apps like Spotify and others.
The GTS 4 Mini does not have this flexibility. Amazfit’s GTS 4 Mini has no user-accessible file storage – it’s designed mainly as a lightweight fitness tracker, not a standalone media device. That means no onboard music or offline maps.
If you want a watch you can use without a phone (listen to music or navigate), the Bip 6 is a better option.
The GTS 4 Mini, by contrast, is suited for someone okay with keeping their phone nearby and who values simplicity.
It lets you install some apps from the Zepp mini-app ecosystem, but key apps like Spotify or Google Maps aren’t natively supported on the watch.
Audio and Communication
One stark difference is audio: the Bip 6 has both a speaker and a microphone, whereas the GTS 4 Mini has only a microphone.
On the Bip 6, you can make and receive Bluetooth calls directly on the watch. With its speaker and mic, Amazfit even built in a voice assistant (called Zepp Flow) for hands-free commands.
The Bip 6 “can make and answer calls like a pro” thanks to its mic and speaker, and you can even reply to texts using on-watch voice input.
In short, it behaves very much like a small, phone-like device on your wrist.
By contrast, the GTS 4 Mini includes a mic for Amazon Alexa, but no speaker.
In practice, this means you can ask Alexa questions or control smart devices, but you cannot have two-way voice conversations or hear Alexa’s voice responses.
In summary, the Mini’s Alexa integration is handy for quick queries or timers, but if calling or replying to messages from your wrist is important, the Bip 6 is far more capable.
Health Sensors and Tracking
Both watches use Amazfit’s BioTracker 3.0 optical sensor suite for health monitoring.
On the Bip 6, this means 24/7 heart rate tracking, blood oxygen (SpO₂) monitoring, stress level estimates, and sleep analysis.
The GTS 4 Mini offers much of the same health data. It provides continuous heart rate, SpO₂, and stress monitoring as well, and also tracks sleep and menstrual cycles.
Along with over 120 fitness programs and sleep tracking. So on paper, the two watches cover the same basic health metrics.
In terms of accuracy, the Bip 6’s newer sensor hardware is as good or slightly better, largely because it’s a newer model (2025 vs 2022).
Testing of the GTS Mini found it “more a rough guide than super-accurate”, whereas early testing of the Bip 6 implied solid reliability.
For everyday use – heart rate zones, step counts, SpO₂ checks – both will do fine. Athletes needing lab-grade precision might prefer a higher-end device.
But for general users, both watches will reliably keep tabs on your basic health stats.
Fitness and Workout Features
If you’re into exercise, both watches have plenty to offer. Amazfit advertises over 140 workout modes on the Bip 6, and I especially liked the inclusion of a special HYROX race mode.
The Bip 6 can connect to Bluetooth HR straps or headphones, track VO₂ max, running cadence, and offers strength/interval training modes (with AI coaching).
In practice, this means the Bip 6 is well-suited for someone who wants detailed exercise data and the ability to expand with external sensors.
The GTS 4 Mini doesn’t quite match that level. It still offers over 120 sports modes – from running and cycling to yoga and swimming – which cover most activities.
However, it lacks the Bip 6’s external accessory support; you cannot pair the Mini with a chest strap or external sensors, and it doesn’t record VO₂ max or pace as precisely.
The GTS Mini simply provides basic stats (distance, calories, heart zones) that are “practical, but standard”.
In summary: If you want a wristwatch that feels like a serious fitness tracker – with sensor support, advanced analytics, and tons of modes – the Bip 6 has the edge.
If you just want basic run/walk tracking and the convenience of an app catalog (plus Alexa), the GTS 4 Mini still covers the essentials and has a user-friendly fitness interface.
GPS and Water Resistance
Both watches have GPS and are swim-friendly. Each one uses five satellite systems (GPS + GLONASS + Galileo + QZSS + Beidou) for location, so their basic tracking accuracy is comparable.
The Bip 6 can also display offline maps and navigate a preloaded route without a phone, which is a nice advantage for hiking or biking.
The GTS 4 Mini must rely on your phone for map data – the watch itself can track GPS routes, but won’t show a navigable map on-screen.
For water resistance, both are rated 5 ATM (up to 50 meters). That means swimming is fine.
Indeed, Amazfit’s product page even highlights dedicated pool and open-water swim modes on the GTS 4 Mini.
In practice, you can wear either in the pool or shower without worry.
User Interface and Performance
Both watches run Amazfit’s Zepp OS, but the Bip 6 comes with the newer Zepp OS 5.0 and upgraded hardware—and it shows. The interface feels buttery smooth, swipes are instant, and apps open without hesitation.
You can even customize the side button to launch your favorite features, and if you’re on Android, you can reply to texts and notifications straight from your wrist. It’s a smartwatch that feels more interactive and capable for daily life.
The GTS 4 Mini runs Zepp OS 4, which is still clean and easy to use, but a bit more basic. You’ll get quick access to Alexa, simple navigation, and all the essentials like notifications, weather, and fitness stats.
What you won’t get are message replies or as many third-party apps. It’s built for simplicity—lightweight, straightforward, and focused on the basics.
Both connect seamlessly to Android and iOS via the Zepp app, but Android users will notice the Bip 6 makes better use of advanced features, while the GTS 4 Mini sticks to a no-fuss approach.
Battery Life
Amazfit is known for long battery life, and both of these watches deliver. The Bip 6 packs a 340 mAh cell that Amazfit claims lasts up to 14 days in normal use.
In real-world use, you can easily get two weeks before charging (with typical features enabled). It also supports fast charging, so a quick 30-minute charge can give you many days of use.
The GTS 4 Mini goes a bit further on a charge. It has a 270 mAh battery but is very power-efficient.
Amazfit claims up to 15 days of typical use, and confirms it too can hit the two-week mark with light usage (even with the always-on display off).
Heavy GPS use will drop this dramatically to around 21 hours, but in normal daily tracking, the battery life is excellent.
Both watches offer roughly a fortnight of life, so neither will need nightly charging in normal use.
Conclusion: Which One Should You Get?
At the end of the day, the choice comes down to priorities:
Amazfit Bip 6: Better for those who want a big screen and standalone features.
It has a larger, brighter display, more internal memory (for offline music/maps), and full call support with speaker and mic. Its fitness tracking is more advanced (140+ modes, accessory support), and its health sensors are newer.
. In our view, if you want a powerhouse budget watch that can work independently of your phone, the Bip 6 is hard to beat.
Amazfit GTS 4 Mini: Suited for those who value sleek design and simplicity. It’s incredibly slim and light – great if you hate bulky watches – and still offers robust basics: 120+ workout modes, Alexa voice assistant, and excellent battery life.
The trade-offs are no calls (mic only), no offline music or maps, and a smaller screen. If you mainly need notifications, Alexa, and fitness tracking from a very wearable package, the Mini is a compelling pick.
Both watches are affordable and well-built for their class. The Bip 6 slightly edges ahead in features and performance, but the GTS 4 Mini looks and feels a bit more refined on the wrist.
Decide whether your priority is “feature-rich functionality” or “sleek compact design.”
In short: if you want to play music and navigate without your phone – or take calls on your wrist – go Bip 6.
If you prefer a minimalist look with just the essentials and an ultra-light build, the GTS 4 Mini is a great choice.
