My understanding is that the options for tuning battery life on Linux are pretty much the same across Linux distros. You either have TLP, Laptop Mode Tools, Powertop, or Gnome Power Manager, all of which tunes kernel settings in a similar fashion. Thermald might possibly help too, but I'm not sure if it has positive effects on battery life. The only factor that I could think of that might make a difference across distros is the availability of hardware video acceleration in browsers. But that gap is likely to close soon, if there are any right now.
