High Sierra Topix

I've sort of taken the plunge, in that I've rented an RX100m3 to use on a 3 day trip this weekend. I'm looking forward to seeing how it performs and what sort of battery life it has. Sadly, I was not able to rent extra batteries, so I may bring a little solar USB charger to top it off...

JWReno, vitaminC, by now the two of you must have a lot of experience with this camera. I'm considering a purchase. Any advice now that you have had half a year with the camera? How has the battery life worked out?
