Lumia 620 issues after black update

[aniket03]

Has any one experienced battery drain issue on lumia 620? Cause i think battery of my device drains very quickly. Hardly 4-5 hours. I use whatsapp, play games i guess for half n hour not more than that. Second issue is wifi its too weird. When i connect to a wifi after sometime it gets disconnected automatically. So i have to everytime go to settings and connect it again. Tried hard reset but that also didn't help me. Help please

And one more issue is my songs. This one is pathetic. All my songs in my phone are doubled i mean duplicates are being created automatically don't know how i tried formatting my sd card. Copied all songs again next again i see duplicates of all those songs when i check my songs list.

Your wifi was probably reset after update to switch off when the screen turns off, go to advanced wifi settings and turn that off.

Double music files is known problem. Search the forum!
WiFi, no idea.
