Bluetooth 5 will quadruple the range, double the speed

I'd also like it to consume less power. I know the current standard touts itself as "low-energy" but I can see a very noticeable increase in battery drain when I have it enabled on my phone. So I always keep it disabled.

This is really a poor marketing job by the Bluetooth SIG. Bluetooth 4.0 added BLE, the low energy mode, but it didn't change anything about the power usage of existing modes.

BLE is almost and entirely different protocol, albeit implemented on the same chipset, which is running alongside the existing Bluetooth stack on your phone. Nothing in the Bluetooth 4.0 spec reduces the power usage of the Basic Rate and Enhanced Data Rate modes.

Seems similar to the mess that is USB 3.1.

One would be lead to believe that 3.1 and the C plug is one and the same, But they are not.

There are actually 3 different specs that the OEMs can combine in various ways.

First is the C plug spec, that can be used with or without the Power Delivery and 3.1 data spec.

Then there is the 3.1 data spec, that is so minor an update to the 3.0 spec that effectively all 3.0 devices are 3.1 compatible. It can be used with A and C plugs alike.

Then there is the Power Delivery spec. This promises that you can get up to 20V out of a USB port, any USB port. Yep, you can encounter A ports that can go up to 20V if you have the right device and cable at the other end.
