High Pebble Battery Usage

[jones139]

Pebble battery usage very high - can flatten battery in <24 h.
Consider reducing data transfer rate to reduce bluetooth comms.

I just wanted to add my experiences here. I have a Pebble 2 HR watch, and from 100% to just overnight (~8-9 hours), it goes down to about 50%. Just wondering, would #3 help with this?

Background: I have been diagnosed with epilepsy myself, so I'm happy to contribute as much as I can to this project, in order to further enhance my computer program for helping with my seizures as well :-)

Really good work you're doing here though, its amazing stuff.

Hi. Thank you for getting in touch.
Issue 3 is about running as a background process. I am confident that it would not alter battery consumption, as I am pretty sure that the battery consumption is dominated by the bluetooth communication. I forgot this issue was open, because I added some notes to the web site a few weeks ago (http://www.openseizuredetector.org.uk/?p=1040), and should have added it here - increasing the data transfer period up to 30 seconds makes quite a big difference to battery life - I'd be interested to know if it does the same on Pebble 2 because I don't have one of those to test on.

It would be great to receive whatever contributions you would like to make - if you would like me to explain how the seizure detector code or alarm system works a bit better let me know, and I will write a little developers guide - I have never quite got around to that!
Cheers

Ah, I see. I wonder if it would make a difference if at all though. Still something to work on..

I tested your suggestion, it made a slight difference, but its still picking up my movements as tonic-clonic seizures, which may be because of my consistent tremor in my legs and hands. More testing is required.

I'd be very grateful if you could that! I've not quite got the full understanding of the detector's internals. Perhaps we could setup a realtime chat for discussion? Happy to do it over anything that's not Slack.. for reasons :-)
