Could you move the remaining time check you do earlier in the loop after |charging| so there, you will check what has to be checked instead of checking for the discharging part and then re-checking if we are actually charging.

So, if we are charging but we were not able to get the remaining time value, we might have remainingTime = kDefaultRemaningTime. We should actually have remainingTime = kUnknownRemainingTime unless we are fully charged. Maybe you could add this:
if (level != 1.0) {
  // Default value that will be changed if we happen to find the actual remaining time.
  remainingTime = kUnknownRemainingTime;
}
after |if (charging) {|.

The patch looks good otherwise but I would prefer to see this change before r+'ing.

nit:
Could you actually change this to:
remainingTime = level == 1.0 ? kDefaultRemainingTime : kUnknownRemainingTime;

Better to be explicit that when level == 1.0, we actually want the default value to be kDefaultRemainingTime.

Reuben, do you have commit access level 1? If yes, did that patch went to try?

Comment 9

[Reuben Morais [:reuben]]

Yes, no. I ran mochitest-2 locally and things were fine, though. I was under the impression that I should avoid sending low risk patches to try since it's already under heavy load.

[Mounir Lamouri (:mounir)]

You could use trychooser syntax and just run mac builds (both debug and opt) and mochitest-2.
