The smartwatch has become an elegant accessory full of functions, but it continues to have the same defect as smartphones: battery life. In this guide we introduce you to four models with a long battery life. 4 smartwatches with a great battery life Amazfit Verge Lite The first smartwatch model we want to tell you about is the Amazfit Verge Lite. From the hardware point of view, it has nothing to envy to the more expensive and noble smartwatch models. It is produced by Huami, a Chinese company funded by Xiaomi. This is a cheaper version than the early 2019 model from which it takes up the design. The design is really essential, with the case and strap in plastic. Although, aesthetically, it is not the most accurate, it remains a very resistant model to shocks or falls as well as comfortable to hold on the wrist. It weighs 43.8 grams, one of the lightest in its category. On the right side there is a single physical button that is used to turn the smartwatch on / off, to return to the Home and to start some features of the pre-installed apps. Among its advantages, there is the possibility to change the straps, the IP68 certification that allows you to wet it in water (fresh water only) and the presence of a heartbeat reader. In addition to the battery life of 20 days, another of the most interesting aspects of this smartwatch is the 1.3-inch AMOLED display and resolution of 360 x 360 pixels. It has deep blacks, a good level of contrast and automatic brightness adjustment. Among the features we mention the flashlight, the night mode, the weather, the stopwatch, the countdown, the alarm and the part related to physical activity. The supported sports are 7 (running, walking, treadmill, bicycle, stationary bike, elliptical trainer and gym). The heartbeat count turned out to be quite accurate, the sleep tracking is quite detailed, the GPS is very accurate and there is native support for Strava. Too bad it is not suitable for swimming, both because there is no registration of swimming sessions, and because it is iP68 certified for short contacts with water. You may be wondering what it is missing. Very little, because it has a large AMOLED dial, the GPS sensor, the heart rate sensor, you can control the music you listen to with Bluetooth headphones and also has a system that monitors the heart rate and alerts the user in case of emergency. We can say that, compared to its older brother, the Verge Lite has neither the microphone nor the speaker that allows the connection with Amazon Alexa, nor the Wi-Fi connection. OshenWatch Smartwatch OshenWatch Smartwatch is a multi-functional smartwatch that gives you the ability to monitor your vitals, use multiple applications, and enjoy the features of a fully functioning smartwatch at a relatively low price.

Withings Steel HR In reality, it is a hybrid watch, because it is an analog watch but with functions that look to smartwatches, produced by a company in the Nokia galaxy. In fact, it has a heart rate sensor, the ability to measure sessions related to physical activity, is also certified for swimming and has a frightening battery life. It has a soft plastic strap that never bothers, indeed, and is also suitable for water sports. It boasts a battery life of almost 30 days. Garmin Vivosport Activity This isn't exactly a smartwatch, but an activity tracker. Suitable for athletes, it has all the useful functions for those who play sports, but in addition it also has the measurement of the VO2 value during training sessions. It has preset sport profiles including walking, running and cycling, 24/7 Garmin Elevate wrist heart rate monitor and integrated GPS. Garmin vívosport allows you to automatically download the data collected on Garmin Connect via your smartphone and the Garmin Connect Mobile application via Bluetooth Smart.

By holding your smartphone close, you can receive notifications of messages, emails, SMS, incoming calls and push notifications. Certified with water resistance up to 5ATM (therefore also in the pool or in the shower). As for battery life, this reaches up to 7 days in smartwatch mode and up to 8 hours in GPS mode. Conclusion The world of smartwatches has become full of models, all more or less elegant and fanciful, with many exclusive functions. However, one limit they continue to have is battery life. Above, we have introduced you to four models that have been successful precisely for those group of users who are looking for a battery life of several days.
