Features of a smartwatch: what to analyze before buying one? — Part 1

Do you know what a smartwatch is and how it works?

If someone asked you to tell what a smartwatch is and how it works, could you describe it clearly? Well, the answer may seem obvious, however, it does not seem so easy to explain. Here it goes with simpler terms:

Smart watches: the most popular wearables

When talking about wearable devices, reference is made to wearable technology, that is, those devices that can be incorporated into clothing and accessories for daily use.

Characteristics of a smartwatch What to analyze before buying it?

The important thing when choosing this class of wearables is that they fit your needs, budget and style, but without neglecting useful tools and properties necessary for their proper functioning. Let’s look at each aspect:


Taking into account that it is a device that you will use to be your digital assistant, it is important that it last more than a day and follow your movements without any pause. So let’s look at the characteristics that matter in this property:

The higher the mAh, the longer does a smartwatch last on?

Well no, the amount of mAh does not determine the time of use, because in addition to this value, the amount of resources and energy that a device consumes to carry out its functions must be taken into account.

How are they loaded?

Its way of charging is simple, the most current ones no longer have a USB input that damaged their design. Now it has a pair of pins to the back, these must fit with the base of the charger that is magnetic.

Operating system

This, together with the processors, are the pair that determines the compatibility of the watch with your cell phone. For this wearable, there are three different operating systems that are the best known. We explain them to you:

Wear OS

Initially called Android Wear, now known as Wear OS by Google, it is the operating system for wearables based on Android. It was presented by Google in 2014 and since then it has had adjustments in its versions to make them more complete.


Operating system developed by Apple Inc and designed solely for the Apple Watch, so you will not find any wearable device with this software that is based on iOS.

Tizen OS

It is the operating system that is based on Linux and is used mainly by Samsung, this is because Tizen OS is open source, allowing adjustments to improve the user experience.

RAM and internal memory

Since these devices store information such as notifications and of course the installed apps, it will be necessary for them to have a memory that is clearly not as large as that of other computers. We tell you everything:

  • Internal Memory : from it it is possible to store data such as received SMS, call log, contacts, app notifications, etc. In addition to the records of functions such as the step counter and blood oxygen measurement, data that you can access and that, to save them, a memory space is necessary.


We could not leave out the appearance of these devices, much less when companies strive to make them increasingly slim and aesthetic, always keeping details of traditional analog wristwatches.

Wearables straps by material

This determines the quality, if you choose the ideal you will reduce the risks of it bursting, getting dirty quickly, or being damaged by rain or dust. In addition, the perfect material will also depend on your daily activities, let’s see why:

  • Titanium: this material is found in the form of silver gray powder and shiny metal, they are usually softer to the touch, so the feeling when using them is more pleasant on the skin. Belts made of this material are too light, but extremely resistant to shock, pollution, water, etc., which increases their commercial value.
  • Silicone


We now come to an important factor. The screen of watches has two main factors that must be analyzed, first, its touch and then the panel. These properties allow the quality of the device to be identified. Let’s look at each feature:

Screen types according to touch

This is basically due to the fact that there are three types of touch screens that are commonly used for wearables, these are: resistive, capacitive and surface acoustic wave.

Screen types according to the panel

In addition, of the categories that we mentioned about the tactile ones, there are also different kinds of screens according to the panel with which they are manufactured, so that you understand a little better, we are going to see each one of them.

Resistance and protection

Let us now turn to a relevant property for those who use their smartwatch as a digital assistant: resistance and protection.

How to know the levels of resistance to water and dust of the watch?

It is classified under a degree called IP, from the English ‘Ingress Protection’ which translates to Ingress Protection. The way to name it is by accompanying the initials with two digits that indicate the quality levels, let’s see how:

  1. It can resist particles with diameter up to 50mm.
  2. It can resist particles with a diameter of up to 12.5 mm.
  3. It can resist particles with a diameter of up to 2.5 mm.
  4. It can resist particles with a diameter of up to 1 mm.
  5. It can resist particles with diameter less than 1mm.
  6. Complete protection and absolute insulation against dust.
  • Protection from drips and very light rain, withstands a slight exposure to water.
  • Protects against moderate rains. Water fall with a maximum inclination of 15 degrees.
  • Provides protection against sprayed water.
  • Provides protection against light jets of water of 10 liters per minute.
  • Provides protection against moderate jets of water of 12.5 liters per minute.
  • Provides protection against strong jets of water, approximately 100 liters per minute.
  • Provides device protection in temporary immersion situations of maximum 30 minutes.
  • Provides device protection in submerged situations. That is, deep immersion in longer periods of time.
  • Provides protection against high pressure jets, between 14 and 16 liters per minute and up to 80 ° C

Functions included

Now let’s talk about one of the most important factors. Once you have reviewed the materials of your watch, design and its operating system, it is time to go on to analyze the functions that it allows you to execute.


Here we are going to find all the tools that work through the sensors, whether they are motion, location, etc., such as:

  • The gyroscope: allows you to measure the orientation and rotation.
  • The compass: for you to go to this tool if you need to orient yourself.
  • The heart rate monitor: commonly used to analyze heart rate, it is quite useful for athletes.
  • The barometer: measures the atmospheric pressure, in this way it calculates the altitude and its changes.
  • Thermometer: with this tool you can know your body temperature.
  • Altimeter: to identify the height above sea level, taken from your point.
  • The geolocator: known as GPS, it provides help in locating within an area.

Dialing and notifications

The functions of the smart watches that you find in this category are: calls, records, contacts, messages and notifications.

  • Registry: it is the access to all the calls received, made and missed.
  • Contacts: so you can see your agenda and dial who you need.
  • Messages: Given the capacity of many of these devices, it is likely that most only store the last 5 messages received on your phone so that you can read them from your watch.
  • Notifications: so you can keep up to date with the interactions you have on your networks and with the messages you receive in your chats. Synchronization with some applications will depend on the phone and your ability to access them.

Additional services

Here you will find other tools that are quite useful and that you can also find in these wearables, such as: alarms, stopwatch, calculator, sleep monitor and music control.

  • Stopwatch: to take time, quite useful for those who want to pass their records in some physical activities.
  • Calculator: not common on all devices, but many allow the use of this tool with basic functions.
  • Sleep monitor: to count the time you sleep and the quality of your sleep.
  • Music control: from this function you can pause, rewind or change the song that you are playing on your cell phone thanks to the Bluetooth link that wearables allow.

Bitwings aims to offer smartphones with futuristic technology to all its customers at competitive telephone rates and transmission of encrypted data.
