I have a couple questions which don't seem to be answered on the website if anyone knows the answers.

1. Is the battery a rechargeable or normal battery that I have to replace?

2. Can I easily download my sleep data to my computer to mess around with?

1. Rechargeable. Lasts about 2-3 nights depending on how long you sleep.

2. Not yet.

The FAQ on the web site currently says 6 nights. Might want to update that.

Could you elaborate as to why it's only 2-3 nights of battery life? I'd expect much more from something like this.

Wakemate uses bluetooth, doesn't it? Thats bound to eat up power.

[Sephr]

Bluetooth shouldn't ever be on except for when it needs to upload sleep data to your phone though (which I assume is done right when waking up).

That's putting a lot of stock into the device itself.

Conjecture: I think it's more likely that the device is something of an accelerometer paired with a bluetooth radio that can nearly continuously feed the phone/app with movement data so that the app can decide whether or not to rouse you.

Rationale: The algorithm. Assuming they want to tweak their actigraphy parameters, if the algorithm is running on the wristband you're going to need to drop new firmware on the device. Field-flashing embedded devices is to be avoided at all reasonable costs.

Field-flashing isn't that bad as long as it can safely be done over bluetooth, and I'd be willing to take that risk to have reasonable battery life.
