It would lighten your load on the ice for sure.no ice pack batteries etc.it charges usb so a little solar or mobile charger but i think you can get 6 hrs or so on a full charge.your,e phone who knows.it has a ice fishing mode as well.found fish caught fish...works for me.non stop rain now.when i get back out ,i was told screen shots no issues.has gps ,you can make and store maps you make through the app after creating a account,cloud storage my guess so it wont ham up your storage on your phone.
