Hello, I have an ipod touch, 5th gen, 64gb (17gb free). I updated to ios8 on day one. Yesterday, I noticed the battery usage is now only showing two apps (facebook 71% and stocks 29%) for 24 hrs and 5 days, before it was showing all apps I have used. Is there any way to reset the battery usage? I let the battery run out completely hoping that would reset something but no luck, its still stuck, Thanks!
