Suggest smartphone under 25k

Hi. Currently, there are many smartphones brands in India. It’s becoming impossible for anyone to zero down for a phone that provides decent features at a good value. Personally, I have used iphone 4S, Samsung Galaxy S3 and currently have Micromax Canvas Knight A350. Now, I want to try out something that defines the latest technology. Don’t want to compromise with 2 important requirements i.e good camera and battery life. Please suggest.

The Nexus devices are the best smartphone that comes with the latest operating system first when ever google releases one. You can also do a lot of thing like customization, rooting and so on with this devices. Currently the best one is Nexus 6 but that is very costly, in 25K you would probably get the Nexus 5 device which is not bad at all.
