From a software development standpoint I don't think there is much they can do about it. They need the GPS position to be updating pretty frequently to get accurate positions. And that is very energy costly. The reason it works better on the iPhone has more to do with hardware, I would suspect. Good and long lasting batteries are expensive and that is where most smartphones skimp a bit. Same goes for energy preserving GPS units.
I am not sure my phone will last a full 18 holes either, It was down to 50% after 9 holes yesterday (starting with a full charge). But I have a small power bank that I can use (those things are really not expensive and they pretty much give you a full extra charge).
That's my plan, what I have been doing is plugging it in to the golf trolley while walking to the holes. It's a shame the club's don't activate the GPS when they are picked up and it goes in to standby when not
in use.
