User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/536.26.14 (KHTML, like Gecko) Version/6.0.1 Safari/536.26.14 Steps to reproduce: Some time ago, I built Firefox from mozilla-central and noticed some battery-related mochitests failing. I got distracted and never gave it much thought, though. So today I built revision aa5e3b445810 and noticed that navigator.battery indeed doesn't work properly for me. Building on OS X 10.8.2 (via make -f client.mk), no build options except for --enable-debug. Actual results: When on AC power, navigator.battery.charging returns false. Also, navigator.battery.chargingTime returns Infinite. Expected results: Expecting navigator.battery.charging to return true, and navigator.battery.chargingTime to return 0 (battery was fully charged). This does happen with a built-by-mozilla (i.e. downloaded) version of Nightly, so it seems that something gets lost during my build.
If you need more insight, I'm absolutely comfortable doing some debugging, but not yet that familiar with the codebase. I tried to set a breakpoint at mozilla::dom::battery::BatteryManager::GetCharging(bool*) to get any insight, but it doesn't get triggered on navigator.battery.charging.
