I completed my first power cycle for my Kindle Fire HDX 2013. It lasted one day and, as measured by GSam, at 15% it had 8:03 Active Time of which 7:16 was Screen Time. I was indexing a Bible Encyclopedia and using Amazon Music Importer to add in my favorite songs while playing the songs most of that time.

The HDX MP3 player was active 23.4% of the time and the Screen was active 43.9% of the time.

My Kindle Fire HD 2012 has run for 8 days and is down to 15%. Its Active Time is 7:20 and its Screen Time is 4:38. The MP3 Player is at 2.4% and the Screen was active 30.4%.

It appears the big battery advantage of the HDX is in Screen Time but it is only slightly better than the HD in Active Time which may have been influenced by the long eBook indexing and the MP3 usage of the HDX.

The HDX took 2.5 hours to charge from 15% to 100%. The HD took 3.5 hours to charge from 15% to 100%.
