How to calculate from those values? Total capacity 350mA or 0.350A
At idle, 0.15mA or 0.000 150A are consumed when there is no movement. When GPS is
enabled, 30mA or 0.030 000A are consumed. Using simple division, Total Capacity / Draw will provide the time in milliampere-hours. Dividing that by the number of hours in a day, yields the expected number of days.
// * Idle *
Total capacity 0.350 000A / 0.000 150A = 2333 hrs
2333 / 24 = 97 days
Note that individual mileage may vary
// * GPS When full on *
Total capacity 0.350A / 0.030A = 11.67 hrs
Through your specific coding technique, GPS could be turned on and off to extend that value
'Both with and without GPS (if that can be turned off)'

YES @user126405 the Bangle and all the Espruino original boards are fun to tinker with!
Simple explanation for battery ampacity
I found the specific answer for Bangle by taking a peek at the Bangle presentation page:
Below the Power Consumption heading:
From there I searched to the bottom of the page at the tutorial icons and selected 'Technical Information'
