qqp question1: My Nexus 6 phone has been heating a lot lately anyone have any suggestions to make it cooler? question2: I have been using my Nexus 5 for the past 6 months. For the last 15 days (maybe after updating to Lollipop 5.1) it has been taking around 2 and half hours to charge from 0-100%. Earlier it was 1 and half hours. Is that a Lollipop 5.1 problem or a battery issue?
