Comparison Huawei Band 10 vs Huawei Band 9

Bezel-less are displays in which the case or bezel does not occupy the usable area of the front panel, or it is minimized. In terms of design, bezels have both pros and cons. One of the most important reasons for adding substantial bezels to your screen is physical protection. The bezel-less display is very easy to scratch or damage when dropped. On the other hand, the frame takes up space on the screen, and this is one of the reasons why the frames in modern smartwatches are minimized, making the gadget more compact and stylish.

The type of battery that is installed in the watch/bracelet.

— Li-Ion (lithium-ion). Battery of the original format, made using Li-Ion technology. Such batteries combine compact dimensions with good capacity, they are unpretentious in use, durable and reliable, and among the significant drawbacks, one can only note some sensitivity to low temperatures. As a result, this technology is one of the most popular in modern portable electronics, including wearable accessories.

— Li-Pol (lithium polymer). An updated and improved version of Li-Ion technology (see above). With the same basic advantages, lithium-polymer cells have even greater capacity with the same small dimensions and weight, they hold voltage more stable as they are discharged and are more resistant to low temperatures. At the same time, these batteries are somewhat more expensive.

— Battery. Powered by a replaceable battery — usually a compact "tablet" of one type or another. Such batteries have a relatively low capacity and are usually made disposable, that is, they cannot be recharged. Therefore, such power is found mainly among two categories of devices: in fitness trackers without a display, as well as watches of a classic design with a minimum of smart features that do not require a lot of energy.

The time that the gadget can work on one battery charge (or the supplied battery) in normal use.

Normal mode, as a rule, means working with a relatively low load. At this time, the display can display some data, and basic functions can also work (counting steps, periodically checking heart rate, etc.), but in any case, power consumption is low. Therefore, the operating time in normal mode can be quite impressive, up to several weeks, or even months. However, when choosing, it doesn’t hurt to also pay attention to the stated time in active mode (see below) — especially if a long operating time is critical, or you plan to use the gadget intensively. The actual autonomy of the device will most likely be somewhere in between these two values, depending on the actual load. If only the time in normal mode is indicated for the gadget, you should choose with a certain reserve.

The time that the gadget is able to work on one charge of the battery in the active mode of use.

For watch-phones (see “Type”), this usually means a talk mode, for other gadgets, an intensive work mode when numerous features and sensors are used and there is a constant exchange of data with a smartphone/tablet. However, the specific understanding of the "active mode" for different manufacturers may vary: some indicate the time at maximum performance (that is, in fact, guaranteed battery life), others — in some kind of "average mode". However, anyway, this is a fairly clear parameter that describes the battery life of a particular model quite well (and is much closer to real indicators than the time in normal mode mentioned above).

Note that for models with a GPS sensor (see "Navigation"), the specifications may additionally specify the time of active operation using such a sensor. See "Operating time (GPS)" for details.

The time it takes to fully charge the battery of a wearable gadget is from 0 to 100%. In practice, this parameter depends on several factors: battery capacity (the larger it is, the longer the charging process will take), the power of the charger and charging technology (support for accelerated charging with increased power speeds up the process of restoring energy reserves in the battery cells). For most modern smart watches and fitness bracelets, full charging time varies from half an hour to a couple of hours. However, the specific time directly depends on the model of the gadget and the characteristics of the charger - it is advisable to clarify these points separately.

The material from which the body of the gadget is made. Some models are available in several versions, made of different materials — for example, aluminium or steel; for such cases, all available options are indicated in the specs at once.

— Plastic. Plastic is often considered a low-cost option, but this is not true in the case of wearable gadgets: such devices can use different types of plastic, including very advanced, durable and reliable ones. So the overall quality of such a case, usually, directly depends on the price category of the device. The common advantages of all types of plastic are relatively low weight, resistance to moisture, the ability to give the body any colour and shape, as well as low thermal conductivity.

— Metal. Cases made of metal, for which the manufacturer, for some reason, did not specify the specific composition. However, most often in such cases we are talking about aluminium or steel, see below for more details on both. But high-end materials such as gold or titanium are rarely hidden under the modest term "metal" — they are usually indicated directly in the specifications. Anyway, in general, metal cases are somewhat stronger and more reliable than plastic ones, they also look more solid, but they are also more expens...ive.

— Steel. Usually, stainless steel is used for wearable gadgets. It is highly durable and reliable, does not corrode, looks stylish and neat, and is relatively inexpensive — cheaper than many aluminium alloys, not to mention titanium. One of the peculiarities of steel cases is rather heavy weight, but it can be both a disadvantage and an advantage: a massive case creates an additional feeling of reliability and solidity. It should be noted that most gadgets with steel cases have round dials and a traditional design, which is well suited even to a business style, but occasionally there are exceptions.

— Aluminium. Aluminium alloys combine high strength and low weight — much less than steel. But this material is somewhat more expensive. It is also considered well suited for bright youth gadgets, although it is occasionally used in more traditional devices.

— Rubber. A material found in some models of children's beacons and fitness trackers (see "Type"), but almost never used in other types of wearable gadgets. One of the key advantages of rubber is softness, which gives a certain degree of impact protection and makes the case as safe as possible; both are especially important for children's devices. In addition, such a case can be easily made waterproof and even completely sealed, as well as made in any colour. On the other hand, plastic has practically the same advantages (except for softness), and rubber costs a little more (although it is noticeably cheaper than metals).

— Titanium. Titanium alloys are premium materials and are rarely used, mainly in top-tier models of “extreme” gadgets. This material is light and at the same time extremely durable, besides it perfectly holds its shape when struck; however, titanium costs much more than the same aluminium, despite the fact that high reliability is not so often decisive.

— Gold. Gold or gold-plated case turns the gadget into a stylish fashion accessory. Such a case is very expensive, but this cannot be called a disadvantage: the price of the device emphasizes the status of the owner.

— Ceramics. Special high-strength ceramics is another premium material that not only performs a practical function, but also demonstrates the high level of the gadget and the solidity of its owner. On the practical side, in addition to strength and reliability, this material has extremely high scratch resistance, which allows it to retain its looks for a very long time even in not very favorable conditions. At the same time, ceramics do not tolerate strong point impacts.

Wrist coverage suitable for the included watch strap. Usually, the length of the strap can be adjusted, so this paragraph usually indicates not one number, but a range — for example, "130 – 200" (millimetres). If there are several straps in the kit, then several ranges are indicated in the specs, if necessary, with a clarification like “fabric: 115 – 185, metal: 130 – 220” (if the straps are made of different materials).

We emphasize that in this case we are talking not just about the length of the strap, but about the girth of the wrist, for which it is designed. Thus, by measuring your hand in an appropriate way, you can accurately determine whether a particular strap is suitable for a particular person or not. This possibility is especially important if the watch is bought for a user with a non-standard hand size — miniature or, conversely, very large.

In most cases, the weight of the watch body itself is indicated as the weight of the model, since the strap is removable and can be replaced with another one. However, there are also models when the weight is presented with an included strap. Anyway, if the manufacturer indicates a specific method of measuring weight (with or without a strap), we add this information.
