I’m looking into other software as well, the battery resume is just one of the many downfalls with pix4d capture. You can readabout my and other peoples experiences here: https://community.pix4d.com/t/3519-PIX4D-Capture-experiences-with-DJI#gsc.tab=0
Others have mentioned some apps that you should look into. Maps Made Easy mobile app says it allows for any processing software to be used: https://www.dronesmadeeasy.com/map_pilot_app
Someone has mentioned DJI Ground Station Pro to me recently but I have not messed with it. They use it in conjunction with http://www.airgon.com/loki.html and said no problems at all.
Best,
Dan
