This does not seem like the right file for these. If they need to be exposed outside of the .mm file, please move them to a more appropriate place or create a new file for them.

Good point! I have moved this to a new file in the new patch.

Thanks for reviewing, Sam!

File naming: A file named "XXXUtils" is against WebKit coding style. Not sure if we wrote it down or not.

I suggest the name SystemBattery.h/mm. But there are probably other good names to consider.

The vague programmer word "utilities" should be avoided, even though this rule has not been followed consistently. Lets not make another header with a name like this. Even just "Power.h" might be OK.

The abbreviation "utils" goes against our stance against unnecessary abbreviation.

Thanks for reviewing! I will update the patch according to the comments :) I think I will go with SystemBattery.h/mm as you suggested.
