Just did the first Battery drain on my new Nexus 7 2013( Fill the device up to 100%, take it down to 14-15% where the low battery warning shows up)
720p Video playbck with MX player Pro (100% brightness, 46.7% max volume with stereo speaker, 16:10 mode for full screen), result:
Looks to be almost 7 hr if I use the whole 100% battery( that last 15min stat always been errorneous, during the playback I documented a drain of about 14.5% per hour
), give this is the full brightness (583 nits, N7 2012 only 312 nits, Ipad 4: 407 nits) it is not too bad. Since I most of the time I will be play video while on charger or a 15,000mAh portable battery(on a plane) this battery life don't really concern me.
But if you were counting on Google's "9 hr video playback battery life claim, seems like you have to lower brightness to that of N7 2012's level (54% on N7 2013 = 100% on N7 2012).Edited by sherlock - 8/15/13 at 11:32pm
