Another vote for Insomnia here. I used to use Insomnia primarily until a lot of my work switched over to gRPC and I’ve found that Postman works a lot better for that. I still prefer Insomnia for the simple UX and speed, just wish it had better gRPC support.
Everything I’ve seen gives it a range between 25% and 96% depending on several factors. It seems like we’re still getting this all figured out and it’s early but if we can get closer to that upper limit it will make a huge difference when considering the impact of these batteries.
