Will Gran Turismo Mobile suck out the battery life of the PSP?

Mine probably gets 4-5 hours, including being asleep for a few hours in between. It does suck battery life though, it'll always drain it faster than MHFU.
Though...This could be because it requires using a brighter screen more of the time on busses/trains, while MHFU doesn't as much.
