Any advice on conserving battery in Studio?

I’m about to go on a road trip to Sydney and I’m planning to continue development on my game there, any advice on how to conserve laptop battery? I’ve noticed that Studio tends to drain it a lot even with low graphics settings and I’d like to be able to save as much battery life as possible (without just editing scripts in sublime text or something since that’s kinda lame and I can’t playtest it).
