Few weeks ago when I updated my phone to 7.0 its battery was working fine. But today in afternoon when I charged my phone too 100%, I used it for a while and kept it aside and it was 82%. After 3 hrs of nap I saw that it almost drained to 55%. I suddenly checked the battery it was showing that ANDROID SYSTEM and PHONE IDLE was using a lot more battery. Please suggest me something that what should I do now???
