I use a Garmin 735XT watch as a fitness tracker. It was at the right price at the right time, and Amazon’s search algorithm did a good job to point it out. I am happy with the device; it works like a charm, and 5-day battery life is class leading.
There is one annoying little thing though.
We interact with our gadgets all the time. We expect our action is met with feedback to show positive or negative outcome. This is crucial, or else the whole user experience takes a beating, and you can get confused.
On the top, you can see the watch has 50% battery left. Should last me a couple of days. I know this. But to be on the safer side, as I am out of the country for three days, I would like to charge it a little more to have a peace of mind that the watch will not run out of juice.
Below you can see, after attaching the charger to the watch, the battery sign does not show the lightning rod which tells me that the watch is charging. This is a simple design feature. The developer seems to have missed it. Not a major issue one but the omission is enough to confuse and degrade the overall UX (user experience). And as you need to charge the watch regularly, you perform this action often. Thus, the user will experience this annoyance every single time!
