Just wondering if anyone else has noticed this. It appears that windows 10 (release preview builds) mobile has been pretty solid on my Icon. The battery drainage seems to be same as before when I am using the phone. The big difference I've seen is on standby. I can have my phone fully charged and unplugged, go to bed and wake up to my phone already down in the upper 70% on the battery. I've trimmed the fat on what is being used in the background but still haven't gotten much improvement on this issue. Has anyone seen this and fixed this issue on their Icon?
