It lasts longer than my iPhone 4S, even though I use it more than I did the iPhone. I turned off LTE and I do not worry about battery one bit - last time I charged to full was last morning - I'm at 35 hours now and down to 15%. So it lasted me "two days" with a typical use:
-> SMS and other messengers (Hangouts, FB messenger, Line)
-> a few calls
-> browsing Facebook now and then
-> reading articles on Flipboard
-> browsing the web a bit in Chrome
-> "a few" YouTube clips of cats :awe:
-> WiFi at home, 3G outside (I spent more time in 3G)
Charging it always at night, so can't really tell how long it takes.
