I agree. I don't see why people are so obsessed with battery, back in the day I could see it, before you could charge in your vehicle, before battery packs, before wireless charging, before bluetooth....even then what we had was considered cutting edge, now we wonder how we survived that technological infancy. So what's going to make the battery obsessed happy? An all week version that weights 5 lbs? They'd just find something else to complain about.
I use speakerphone all the time but if it's an issue I can switch to AirPods.
