Since September 1, he has been testing batteries in Garmin Instinct and Garmin instinct Solar watches
The battery lasted in both watches until September 16.
The specifications show that the first generation garmin instinct should last 14 days and tested it with a 24/7 heart rate measurement it lasted 16 days! so it is better to buy this watch than the Garmin Instinct Solar, which in the specification has 24 to 54 days in charging mode solar energy - In my opinion it does not work, because it keeps the same amount of time as the first generation !! Soon I will start recording videos on the YouTube channel comparing both watches, what are the differences between them. At the moment, I am very disappointed with the Garmin Instinct Solar model.
