Amazfit Balance vs GTR 4: real differences and which one is worth it

The showdown between Amazfit’s two watches is decided by details that, on the wrist, matter more than they seem: a slightly larger display, newer sensors, contactless payment, and battery life that changes depending on the usage mode. On the outside they share the same design language, but inside one is born with higher ambitions and the other retains the aura of a sensible buy.

The scales are not tipped by the technical sheet alone. The newer model bets on a more complete experience for health and sport, while the older one remains a very solid option for anyone who wants a well-rounded smartwatch with good battery life, reliable GPS, and a friendlier price. In Spain, moreover, the store price often decides the verdict just as much as the hardware itself.

Two nearly identical watches, but with different personalities

At first glance, the resemblance is deceptive. Both feature a 46 mm round case, an aluminum finish, and a clearly sporty-elegant approach—that middle ground that lets you wear them with a technical T-shirt or a button-down shirt without looking out of place. Both aim to be watches for almost everything: training, checking notifications, tracking health, and not depending on the charger every night.

The real difference appears when you look at the whole picture calmly. The Balance raises the bar in display, sensors, and wellness functions; the GTR 4, meanwhile, keeps a very solid recipe and is usually found at a much lower price. In a comparison like this, value is not always about having more numbers, but about what each one adds to everyday use.

That is the key to this pair: they do not compete like a high-end model against a basic one, but as two very close interpretations of the same concept. One refines and fine-tunes. The other offers almost everything important without straining your wallet as much.

Design and display: same silhouette, different feel

The aesthetics are almost identical. The Balance features a 1.5-inch AMOLED display with a resolution of 480 x 480 pixels, while the GTR 4 comes in at 1.43 inches and 466 x 466 pixels. The difference is not obvious in a catalog photo, but it is in use: the Balance’s panel offers a bit more surface area and slightly higher definition.

Both retain 5 ATM water resistance and IP68 certification, a combination sufficient for swimming, training in the rain, or not worrying about sweat. The glass and anti-fingerprint treatment help keep the screen readable outdoors, a useful aspect for anyone who runs at midday or trains in summer, when the light turns almost metallic.

Weight also plays a role. With the strap, the difference is minimal, and without it we are talking about barely a gram. Even so, the Balance gives off a slightly more refined feel thanks to the larger screen and the somewhat more modern construction, while the GTR 4 retains a classic look that still works very well. It is not an old watch; it is a design that ages with dignity.

Sensors and health: where the Balance pulls ahead

The main technical difference is here. The Balance includes the BioTracker 5.0 PPG and adds a temperature sensor, heart rate variability tracking, and body composition measurement via BIA. That allows it to go beyond pulse and sleep: it offers a broader reading of overall physical condition, placing it a step above in preventive health and personal analysis.

The GTR 4 still has a very competent sensor set for heart rate, blood oxygen, stress, altitude, barometer, accelerometer, gyroscope, and compass. In day-to-day use it more than holds its own for training, walking, and sleep tracking. However, it does not include the newer elements that make the Balance a more ambitious watch in wellness metrics.

There is also an important nuance for athletes. The Balance adds readiness or preparedness level readings, a function that combines sleep, previous load, and overall status to suggest whether the body is closer to exertion or recovery. It is not magic, but it is a useful way to translate scattered data into a simple signal. The GTR 4 does not reach that level of synthesis.

Sport and running: both work, one looks further ahead

For running, walking, or cycling, both perform solidly. They have GPS, pace tracking, distance, elevation, routes, and multisport modes. In terms of numbers, the Balance reaches 156 sports modes and the GTR 4 154, a symbolic rather than decisive difference. What matters is not so much the number as the consistency of the recording.

The Balance adds a practical advantage for anyone who trains with some structure: better running alerts, performance estimates, and a more advanced layer of guidance through Zepp Coach. For a recreational runner who alternates easy runs, intervals, and long efforts, that extra layer can be more useful than a simple list of sports modes. The watch aims to provide context, not just count steps.

On routes and outdoor workouts, the Balance also gains nuance. Its compatibility with Galileo and the presence of a circularly polarized GPS antenna point to more refined positioning in certain conditions. The GTR 4, for its part, remains a very serious watch in terms of accuracy and is more than adequate for real-world use, but it is no longer the one setting the technological pace within the lineup.

Connectivity, NFC, and calls: the detail that changes the routine

The Balance includes NFC, and that opens a very specific door: contactless payments. It is not a feature that changes a workout, but it does reduce friction in everyday life. Buying bread, finishing a set of intervals and stopping at a vending machine, or heading out for a run without a wallet becomes more convenient when the watch also works as a payment method.

Both let you answer calls from the wrist, include speaker and microphone, and connect via Bluetooth 5.0 and Wi-Fi 4. Use with Android and iPhone is covered, and synchronization with the Zepp app keeps things fairly clean, with no ads and with activity and sleep reports presented well. The experience is similar, although the Balance adds a touch of sophistication thanks to its newer software.

In voice and smart features, the difference is also noticeable. The Balance arrives with a more modern focus, more geared toward contextual use and data analysis, while the GTR 4 maintains a more classic relationship with the smartwatch: notifications, calls, music, alarms, and sports tracking. That is enough for most people, yes, but it does not aim as high.

Battery: long life, but not identical in every scenario

Both share a 475 mAh battery and promise up to 14 days of typical use, with about two hours for a full charge. On paper, it looks like a clear tie. In practice, the specific usage mode changes the picture: the GTR 4 offers up to 44 hours with GPS compared with 26 hours on the Balance according to the reference compared, a notable advantage for long outings or weekend getaways.

The Balance responds with greater endurance in power-saving mode, where it can stretch to 1,200 hours versus 576 hours for the GTR 4. That figure matters less for someone who trains every day, but it does matter for anyone who uses the watch as a constant companion and forgets to charge it for several days. It is battery life that resembles a well-stocked pantry: you do not notice it until you need it.

The right reading is this: the GTR 4 better protects long GPS sessions, while the Balance pulls ahead if you prioritize power-saving mode and the more modern ecosystem. Neither suffers from battery problems in the classic sense of the term. Both are well above many more expensive watches, and that explains part of their success among users who do not want to live attached to a cable.

Software and user experience: Zepp remains the centerpiece

The Zepp app is the invisible heart of both watches. That is where workouts, sleep, heart rate, stress, recovery, and daily goals are organized. The interface follows a fairly clean logic, with easy-to-read reports and an organization that avoids clutter. For the average user, that is worth more than a long list of scattered features.

The Balance comes with Zepp OS 3.0, while the GTR 4 launched with Zepp OS 2.0, although some updates have brought it closer to the newer version. The difference is no longer as stark as at launch, but the Balance retains an advantage by being born with a more mature platform and by integrating advanced health features better.

In feel, the Balance is more ambitious. The GTR 4, however, still offers an agile, stable experience that is more than enough for those who do not need body composition functions or fitness readiness readings. That is one of its virtues: it does not try to be anything other than what it is. And in consumer electronics, that also counts.

Price and real value: how much each euro matters

Price is the GTR 4’s most straightforward argument. In the comparison referenced, the Balance appears at around 168 euros and the GTR 4 at around 100 euros, although the Spanish market shifts those figures with promotions, stock, and specific stores. The difference can be decisive if what you want is a capable watch without pushing the budget too far.

The Balance costs more because it offers more: NFC, a better display, more current sensors, HRV, temperature, and body composition. The GTR 4, on the other hand, relies on a very good relationship between features and cost. Its proposition is less futuristic, but tremendously rational. For anyone who prioritizes a smart buy over the latest advance, it still makes a lot of sense.

In pure value, there is no absolute winner. There are two types of purchase. One for the user who wants to get more data and more functions, and one for the person who prefers a complete experience without overpaying. If the price difference is small, the Balance takes the lead. If the GTR 4 is found with a serious discount, its value for money becomes very hard to argue against.

What each user profile is buying

The Balance is a better fit for someone who sees health as a system, not as a sum of separate metrics. Its battery is still good, but its real value lies in what it adds: fitness readiness, body composition, temperature, HRV, and NFC payments. It is the more well-rounded watch for anyone who wants more than workout tracking.

The GTR 4 retains a clear advantage for anyone who wants a serious, attractive, and more affordable sports smartwatch. Its screen is a bit smaller, yes, and its sensors are older, but it still offers GPS, full sports tracking, calls, music, and very convincing battery life. For most everyday uses, it does not feel lacking.

The gap between the two is not huge. That is what makes the comparison interesting. There is no clearly obsolete watch or massive generational leap, just a gradual evolution. On the wrist, that nuance turns into a very specific decision: pay less for a tried-and-true formula, or more for a more complete and updated version.

The verdict that the comparison leaves on the table

The Amazfit Balance is the more complete model. It wins on display, sensors, health functions, NFC, and overall refinement. It makes more sense for anyone who wants a daily smartwatch with real ambition in wellness and sport, and for anyone who values the watch being more than an activity monitor with a nice strap.

The GTR 4 remains the smartest buy if price is the priority. It maintains a very solid foundation, delivers the essentials competently, and boasts excellent battery life in GPS use. It has not aged badly because it was born with a good formula, and because its balance of design, function, and cost is still very competitive.

The difference between the two, in reality, is not whether one works and the other does not. Both work. The question is how much you value the improvements that the Balance adds on top of a watch that was already very capable. That is where the decision lies, and also its journalistic interest: two models that look very similar, but are aimed at quite different purchases.
