Nexus 7 32GB Battery Run Time
« on: November 05, 2012, 01:16:12 PM »
Just wanted to report for those of you that are interested.

I saw this battery run time on Tom's Hardware that reported a battery run time of 9:40 for a movie with 100% brightness and 50% audio.
http://www.tomshardware.com/reviews/nexus-7-test-jelly-bean,3249-6.html

Tom's test was done with an 8GB model and not with a 32GB model so I decided to run my own test.

Configuration:
-  Nexus 7 32GB running 4.1.2
-  Brand new configuration - no apps other than what was preloaded
-  Downloaded Transformers (as transcoded by the Play store

My unit ran for 9 hours 22 minutes  So Tom's test ran for 3% longer than my test.  Probably within normal variation.  I'm not complaining.

Caveats:
-  I did have to shut the unit down over night, so whatever power the unit drew when the unit was powered off was not calculated into the run time.  Note:  When I shut it down, I was at 62% battery, when I turned it back on the battery read 62%.

Notes:
-  Mine is the 32GB model so theoretically more RAM consumes more power to refresh (albeit I am sure negligible amounts of power extra), but in this case, I don't know how much that impacts.  I really don't know how much more RAM that 16GB (if any) was used to play the movie.  I doubt any.  Maybe this accounts for the 3% variation?

Anyway, for those curious, those are my numbers for what it's worth.
