Battery Test 1

A project log for Flora BLE Smartwatch

Using the Adafruit Flora with a BLE 4.0 module and a neopixel ring, I created a compact smartwatch with a flexible 3D printed enclosure.

I am currently using a 3.7V 100mAh lithium ion battery. So far I have run two tests: 100% brightness (too bright to view) and 5% brightness (my optimal viewing preference).

100% brightness - 2hr 22mins
5% brightness - 5hr 45mins

This is without any bluetooth or further battery optimizations. I am also looking into upgrading to a 500mAh battery as there is still plenty of room left to add a bigger battery.

You do have to disconnect to recharge, however the batteries are very cheap ($2-7) and can be swapped while the other is charging.
