Build the ability to airdrop or “Apple pay” type of technology but to share battery life.
Use case: I was recently at a sporting event with my daughter and needed to leave her there and I didn’t have a charger to give her. Her phone was at 11% and mine at 76% I wish I couldn’t texted her some of my battery power or tapped my phone to hers and approve a battery life transfer. Sending this thought to others who would know better how to make that a reality.
