Comment 5 for bug 1540062

Here another graph produced by reproducing the test case on arale which exposes the HW fuel gauge through sysfs.

This graph shows that the capacity returns by the battery driver and the capacity returns by the battery meter are the same. THat would eliminate the case where the battery driver and the fuel gauge are diverging.

The voltage graph shows that voltage decreases linearly for about 14 hours, then decreases faster and faster for 4 hours until it reaches the lower limit of 3.4V and the devices shuts down.

When it reaches 3.5V the percentage starts dropping to reach 0% in half an hour.

3.5V corresponds to the value of low power wakeup (and 3.6V for the normal wakeup)

The battery meter table shows that 3.6V also corresponds to a DOD of 97% at 25°C, although the percentage reported by the fuel gauge is still 20% while it should be around 3%.
