Why buy a smartwatch with a good battery?
Battery life of a smartwatch is one of the key factors when a smartwatch is chosen. It's really important since it makes no sense to have a smartwatch that has a good screen, camera or processor... if the battery lasts so little that we can't enjoy the device. Therefore, we should choose the right size of the battery. This is usually measured in mAh and the battery life is greater the higher this number is. For example, a battery of 300 mAh in a standard smartwatch of 1.3 inches can last, with heavy use of the device, about 24 hours. However, if you have a smartwatch with larger screen size should look at the device with a higher capacity battery because otherwise it would not last 24 hours on.
Obviously, a normal user who only uses the smartwatch occasionally to make phone calls, and search on the internet or make exercise... without making use of it heavily, does not need the smartwatch with best battery on the market, since it can last more than a day without problems. However, a person who spends long time taking photographs or using whatsapp... needs a battery with more capacity in the device, especially if the screen will stay on continuously.
