I just had my 5's battery replaced a week ago and had been enjoying a full days usage again. Installed iOS 8 yesterday, today my battery was like it was never replaced. Light usage and I was already at 32% at 2pm. Checked my usage and both the standby and usage were the same. Right now I'm at: 17% battery usage and standby are 10 hours 39 minutes. Messages 27% Phone 24% Home and lock screen 23% ! huh? Safari 12% rest seem normal under 10% Anyone experience this today with iOS 8? My 6 plus will be here tomorrow so I'm not that concerned, however I'm giving this phone to my father and would like to know what the problem is, so it can be corrected before I give him it.
