Comparison Xiaomi MiJia Electric Shaver S700 vs Xiaomi MiJia Electric Shaver S500

The speed of rotation of the electric motor of the shaver. A higher rotational speed (ceteris paribus) usually means a higher speed of movement of the blades, which has a positive effect on the closeness of the shave.

— Turbo mode. The function of a short-term increase in the speed of rotation of the motor. This increases the performance of the shaver, which can be especially important when working with thick hair or in hard-to-reach areas. Note that the turbo mode, usually, is not intended for long-term operation.

— Auto-detection of bristles. The electric shaver's head contains a sensor to detect bristle density or stiffness. Through the automatic stubble feature, the shaver's motor adjusts power according to the skin area's requirements. This capability facilitates effective one-pass shaving, even with thick stubble. As the shaving head transitions from dense to moderate bristles, the motor power decreases automatically. This not only conserves battery life but also provides a gentler experience for the skin.

— Floating head/foil. The floating or movable shaving head(s) are capable of moving relative to the shaving unit and shaver body. Such a system follows the contours of the face during shaving, which ensures a tighter fit of the shaving heads to the skin, as a result — a cleaner and better shave, especially in difficult areas.

— Possibility of washing with water. Possibility of washing the shaving unit with water. This method is often much more convenient and effective than dry cleaning with a brush or other method.... Note that being washable with water does not necessarily mean wet shaving (see above).

— Cleaning indicator. A special indicator that notifies the user of the need to clean the shaver.

— Self-sharpening blades. Blades made using a special technology, thanks to which they sharpen themselves, due to friction against each other in the process. Thus, the blades remain sharp at all times, and their maintenance is limited to the replacement of worn blades.

— Child lock. Shavers featuring a safety switch are designed to activate only when held in the user's hand and intentionally turned on. This design prevents unintended activations, such as during travel when the device might shake inside luggage, avoiding unnecessary battery drain during idle moments.

— Case. Cases include all kinds of rigid structures for storing a shaver. Cases in the form of handbags made of thick fabric also fall into this category. In addition to reliable storage of the device, they also elevate the model to the highest class. In more low-cost electric shavers, a much more primitive fabric case is included in the package.

— Charging stand. A special stand on which the shaver can be installed to charge the batteries. There are no fundamental technical differences between such charging and charging from a power cord, the main difference is that the stand can also be used to store a shaver. Therefore, shavers with a charging stand are well suited for home use.

— Wireless charging. A special stand that charges the shaver without a precise connection through the plug — just put the electric shaver on it and the battery pack will automatically start recharging. This saves the user the hassle of connecting wires and reduces wear on the connectors. On the other hand, such a function has a significant impact on the cost of the battle and increases the duration of the charging process itself, since the charging platforms themselves are made low-power for safety reasons.

— Self-cleaning station. It is a special stand where the shaver is installed for automatic maintenance. This maintenance, as the...name suggests, primarily includes cleaning — the shaving unit is cleaned of hairs and dust - as well as charging the battery. In addition, self-cleaning systems can provide lubrication and disinfection of the shaving unit, but this function is less common and requires the use of consumables (oil and disinfectant).

— Facial brush. It is convenient to clean the face from the cut bristles with a brush. The brush that comes with an electric shaver usually has a medium bristle length. Some electric shavers are equipped with a universal brush, which is designed for both cleaning the face and combing the beard and mustache.

While higher battery capacity theoretically extends a device's operation on a single charge, practical considerations are more complex. Ampere-hours are a specific unit, comparable only among batteries with the same voltage. For differing voltages, capacity must be converted to watt-hours for accurate comparison. Furthermore, actual tool battery life depends on consumption and performance, not just battery properties. Comparing battery capacity is meaningful only when models share the same voltage and capabilities. Operating time is a more informative parameter for comparison.

Charging time for the electric shaver battery from a fully discharged state to 100% charge. If freedom of movement when shaving is most important to you in a cordless shaver, and you always have access to the power supply (for example, you rarely travel), this parameter does not matter much. However, if you often travel on trips in which you have to constantly move from place to place, you should pay attention to models with a short charging time.

The ability to switch the voltage for which the shaver is designed, adjusting it to the characteristics of various electrical networks. This feature is useful for those who often travel abroad: in different countries, the voltage in the outlet can also be different. For example, in Europe and most Asian countries, 230 V networks are used, but in North America the voltage is 110 V.

In the simplest models with this function, the voltage is switched manually, more advanced shavers have an automatic network adjustment system.

The presence on the body of the shaver own display, which can display various service information. The display can be equipped with its own backlight. Its presence makes the use of the shaver more convenient, but significantly affects the price of the device.
