Battery drain of 20% at night without any use on nexus 5 I have recently replaced my battery on the nexus 5 . I thought I would be looking forward to a huge battery life difference but I was surprised that even with the new battery the drain is 20% at night . The phone is in wifi mode , no google now , no high brightness , greenify kills facebook app and still the battery life sucks.
I recommend you try wakelock detector to find what is waking up the cpu and preventing your phone from deep sleeping. You might find that is it is something annoying like media scanner getting stuck and killing your battery life.
