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

2\. Not yet.

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).

~~~
brandon
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.

~~~
Sephr
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.

~~~
brandon
So, again, I don't know anything about the device in question, so this is all
conjecture... _but_ :

Even given that OTA flashing is possible, why bother? The device has no means
of waking the user without a phone in bluetooth range, so what's the upshot? I
don't know that battery life falls into that category because the device would
need some pretty serious upgrades, and cost would obviously increase:

\- More RAM. Lots more. Enough to contain an entire firmware image during OTA
and an entire night of sleep/movement history.

\- More MIPS. Actigraphy isn't going to be as cheap

 That's putting a draw 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 receiver that can nearly endlessly feed 
 the phone / app with movement data so that the app can decide whether or not to 
 rout out you. 

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

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