I think Google play music is utilizing its wolfson DAC pretty well now than it came first out of the box. I may say it is comparable to the latest model boasting of HIFI DAC. I have Vivo V3 Max I can say it can stack up against it.i send the feedback problem about camera bt till now I got no respond. its of LG NEXUS 5.What do you expect from a 2300 mAh to power a "5/1080p display? A Moto E 2nd gen has a 2390 mAh only needing to power a modest Snapdragon 410 and 4.5/540p display and it last maybe 2.5x longer. Both Nexus 4 and 5 have awful battery life as seen with the endurance rating here of 32hr and 38hr. Expect to kill 20-25% every hour when the screen is on. And it came from 2013, so degraded battery is already there. A "5 720p should be powered by a 2500 mAh minimum. For 1080p, should be 3000-3200 mAh minimum.
