Its a very very very bad mobile with respect to battery back up. customer care says its normal and suggested to avoid downloading more apps. I am using iphone also and blackberry also those are very good and takes lot of app load. one should never take this nexus mobile. I did the mistake 3 years back and still suffering even unable to sale off in market. people deny to buy it second hand. I had good hope from this handset but LG nexus 5 has disappointed me well.
