I bought the lg nexus 5 around 1.5 years back for 30k(32 gb variant).One of the best phones I have ever used.It runs most of the the games and the screen size is perfect.Video output is pretty good.Its a very tough phone, fell many times from a good height but survived all the falls.The camera is pretty good and the best part of the phone is it gets updated to the latest os within no time.other than that there are many app updates that go on. I am still planning to use the for around 1 year and I think it will survive.Truly one of the best phones in the price range.The same phone will be available for even lesser now.
Coming to battery life it stands by for a whole day for normal usage.If you are using it to play games it will depend on which game you are playing.But average battery life for gaming would be 3 hours. the only issue I found with this phone was the audio output from speakers is a little low.
ALL IN ALL ITS A VERY GOOD PACKAGE.
