Comment 3 for bug 1410495

Same issue here, once the battery drops below 30% it's shown as red, but there's still plenty of time left (1:32 when I took the attached screenshot)
If the color really has to change at 29%, I'd be OK if the indicator was yellow, but I'm just fine with the normal white one. Rred is just not reasonable.

The Android phones I've had start warning about low battery at 15%, that seems fine to me.
